Trans Twins
Chapter Two
By the time the third week started and we were learning about cross species transitioning the idea of who would be assigned as our partner was confirmed. Pierre would be with me for at least the first two missions. Reynod came to the corner where Pierre and I were studying the anatomy of the Canods, the instructors had brought a corpse for us to study. Reynod was hoping that I would go with him to try getting the Admiral to change our partners so he and I could work together.
The last three days with Mr. Downing had been disgusting if not gross. For three weeks we had been working on our ability to shift into different people. The last three days we were preparing for cross species shifting. The preparation had involved moving our internal organs, to see what we were doing we had been taught to shift the skin on our torso to a transparent covering. If anyone screwed up there was a lot of blood flowing through our bodies, blood that was visible to our partners and teachers.
We had been told that we would be permitted to have sex with any of the group in any manner they or we wanted. If the rest of the group was like me there hadn't been time or energy to become involved sexually with anyone. I had hoped that once Mr. Downing had given the go ahead that Pierre or I would be able to move our friendship to the sexual relationship we had promised the other. Having only orgasmed the one time in three weeks I was almost desperate for an ass to fuck but every night when I left whatever class I had attended I returned to my room and fell asleep reading the laws and regulations the Intergalipol had determined we would be enforcing.
It wasn't that there were that many new laws to my mind, it was that each Arm of the Galaxy had only been willing to have an outside force enforce a mixed web of them. We were not going to be a standing police force, for now we were only going to the different planets when requested. The two missions that the Admiral had agreed that Pierre and I would have during the first three weeks were basic Interplanetary smuggling operations, one of Phrotines from their home planet to Cano. The other was one I was more familiar with, the movement of Titanium and drugs between planets in the Perseus Arm of the Milky Way.
Neither of the missions was that complicated, we had been requested to complete an investigation run by the planetary authorities. We were to use the special powers built into the spheres to intercept the smugglers on a route that the authorities had predetermined. It was the first time that we were able to use all the power the spheres had. We didn't even land on Anki once we had captured the smugglers, we towed their super shuttle to Titan where there had been built a prison for criminals that would not be given an opportunity to prove their innocence. The smugglers were from Xibab, I was glad we hadn't needed to face them in a hand to hand to battle they were truly frightening.
The other smuggling operation was more difficult for us to shut down. Sitting in space a few kilometers from the surface of Aphrotitus the sphere was difficult to hold in orbit while we kept it transparent. We were recording the traffic leading to two Xibab Interplanetary yachts. From where we sat the yachts were the most beautiful space ships I had ever seen, Pierre brought up their images on the ship's computer. The close image was truly one that was created for beauty if not any thing else, there were supposed to be able to hold five hundred Phrotines. I had never seen a Phrotine until the second day, if the ship could hold five hundred of them it surely was spacious enough for the Pakabans to wander from one end of the ship to the other without ever seeing one of their fellow smugglers.
Our Flovian trainer had been dispatched with us to make sure that we didn't create chaos due to being too tired to operate the Sphere. For the first five days the Flovian had presented as male and acted the part, we were headed home after dropping one of the Xibab yachts at the Martian space port when he began talking to us about the night he had spent with my Brother. I hadn't expected him to ever talk about getting a blow job from my Brother so when he told us that it was the first time he had ever had a human sexually I was astounded that he offered up his mouth to try sucking our cocks. Pierre quickly removed his space suit and told him that he was willing to let him try.
I hadn't been attracted to the little man but seeing Pierre with an erection did what it had done to me every time I had seen him without clothing. I wanted to fuck my friend but watching him get sucked off by the Flovian changed my mind, I undressed and stood over the pair waiting for the blue man to finish with Pierre and start sucking my cock. It had always been one of my fantasies to have sex in space so when the Flovian put his lips to my cock I was ready to give him a load of cum. For a few minutes I stood with him between Pierre and I, I loved it when Pierre pulled my head to his and kissed me with as much passion as I had ever imagined there would be between us. I reached down to put my hand on Pierre's butt, he guided my fingers until I was pushing two of them into him.
That was as long as I could hold back from shooting a load in the warm mouth. The Flovian left us standing there kissing with both of us fingering the other. The longer we kissed the more I understood that I didn't want to just fuck Pierre, I wanted to make love to him like I had never made love before. I mentally thanked the Flovian for breaking down the resistance we had to doing more than kiss and touch. Pierre pulled me to the bed we had alternated using and lay down raising his legs until my cock was touching his asshole.
"Tristan, please use some lotion." That he was actually ready for me to split him open was wonderful, I found a tube of lotion that had been stored over the bed and squirted some of it on his asshole. He asked me to squirt some of the lotion on his hand and moments later was spreading it up and down my cock. I had expected him to be too tight to push into easily but he had been waiting for this for so long that as soon as the head of my cock pressed into him he widened his asshole enough that I slid in the whole way.
We must have made the Flovian come back to the bed with the noises we were making, Pierre was moaning in pleasure and begging me to fuck him harder. While I fucked him I licked and sucked at every part of his body I could reach paying the most attention to his beautiful brown nipples that hardened as I sucked on them. I loved the taste of his body so much that I wished that the Flovian hadn't made him cum, I wanted to get my mouth on his cock and enjoy the taste of his cum.
I really had never enjoyed a threesome unless one of the other two had been my Brother sucking on my cock to get me hard enough to fuck the third. I was glad that I had given the Flovian my first load of the week, I was able to hold back as I fucked Pierre until the Flovian shocked me by sliding his blue tongue in my asshole. Soon after I spent a load in Pierre's asshole he flipped us over and put the head of his cock to my wet asshole, I had never been with anyone that wasn't cut before that and had no idea that a man could use his foreskin to ease his way into an asshole. It was completely different than anything I had ever had allowed to happen to me, a seven inch cock is so much different than a man's tongue even when the man was trying to be as careful as he could.
The nights I had thought about having Pierre in my ass I had expected him to take me doggy style but there I was with my feet on his shoulders having him use all of his length to give himself and I true joy. Pierre had his cock in me for at least ten minutes when the Flovian announced that he was turning off the artificial gravity. I was afraid that Pierre and I might drift apart but he was holding on to me so tightly that we drifted as a pair, flying united. I was pushing against the wall separating the sleeping area from storage when Pierre took a sock from my foot and sucked my toes into his mouth.
There had been boys in college that would suck toes, however I didn't expect Pierre to want to do more than lick my pits and nipples. If we were long enough I think he would have been happy to suck my cock while fucking me. He had a suction motion that was as good as any I had ever felt on my cock. When I told him that he let me know that before we arrived on Earth that he planned on sucking my cock until I wasn't able to get hard again. I didn't tell him but that was almost impossible, I had never had a mouth on my cock that hadn't made me erect although I had gotten to the point where I couldn't shoot any more cum.
Fucking while floating around the sphere was an experience unlike any other. He had gotten the idea that he would need to maneuver my body with his hands and arm muscles more than pushing his cock in and out of me. It was unbelievable that I didn't want him to stop, I had often fucked guys that had begged me to stop; that was my first time enjoying a dock in my ass. I hadn't known that I would love having his cock in me that much, I tried whispering my feelings to him only to have him say that he was so happy to be in me that he didn't ever want to stop.
I really don't know how long Pierre was in my ass before he finally was able to shoot another load in me. Shortly after he yelled that he was cumming the Flovian turned the gravity on again and we fell to the bed causing Pierre to slide out. I asked the Flovian if he wanted one of us to take over, he let us know that we would be on auto-pilot other than for the few minutes while we entered Earth orbit and he would be willing to stay in the pilot's seat until we were docked.
I thought we should get dressed but Pierre wanted to lay on the bed skin against skin, I couldn't refuse him anything at that point. Unexpectedly he began talking about more than sex, he admitted the feelings he had been having for me were stronger than any he had ever had for any of his previous female partners. We both spoke of how we felt when in the other and having the other on us. I had never had what would be called a boyfriend, most of my past partners had been one night stands although there had been a few that had lasted a week or so. We both thought that getting to know each other for a few weeks before we finally moved onto sex would be a good basis for our relationship as partners in space and in bed thinking that we were starting something that would be great for the rest of our lives.
Pierre had developed a love for my cock, I didn't know whether it was while I was in him or seeing and touching each other at the clinic. Laying beside me he threw a leg over mine and slowly moved until my cock was sliding into his asshole without me having to push into him. Soon he was fucking my cock like a whore would a dildo, when we entered Earth's atmosphere the sphere bobbed around making me fuck him harder than earlier. That was all I needed, I wasn't going to give up fucking him.
"Mr. Downing, why were we allowed to miss the first week of cross-species shape shifting? I would have thought it was the most important week of training we could get."
"Tristan, you and Pierre are both quick learners. I didn't think you would fall more than a few days behind that you could make up by the time you are heading into the second week. Plus, the Admiral wanted two of the class out in space getting knowledge about traveling in your sphere and to see if we have partnered the right people. Both of the planets you orbited have extensive experience with humans so if there had been a reason you had to land you would not have needed to know how to shift cross species."
"The smugglers hadn't seemed to have that much experience with humans although half the crew that was trying to take the Phrotines off of Aphrotitus spoke English as well as the Flovian with us.
"Has Intergalipol reached a decision on whether we will be given possession of the Space Yacht we seized? Pierre and I think the yacht should be available to anyone in our class, I'm aware that we will never have the resources necessary to fuel the ship or the manpower to operate it unless the whole class is involved in its future."
"Admiral Broughton was on the committee that wrote the regulation not permitting the force to seize anything being smuggled for personal use. That you turned one of the two yachts over to the force on Mars has made her listen to the arguments being made for the second yacht being based here.
"The pair of you need to work at transitioning your torsos to the transparent skin I had you develop the last few days of your classes with me. You will be back in class first thing in the morning." He had invited us to have dinner with him in the executive suites of the clinic, it was the first time we had seen his wife. I suppose it is for the best that there is no way to determine if a good transition has occurred, Mrs. Downing was about the same size as her husband and much better looking than I would have expected him to have for a wife.
Dinner was much better than the food we were served in the dining room. I had never been well educated in casual conversation so I let Pierre take the lead when we were expected to speak. We were eating desert when the topic of what Lyla did for a living was first broached. She was glad that we were finally talking about something that she was better speaking about, it turned out that she teaches art classes, primarily anatomy.
"Tristan and Pierre, my husband has told me that the two of you are the best in your class at shifting into other humans forms. I have asked him to allow you to pose for my classes but he has repeatedly told me that it would be up to you. Two of my classes are working on painting men from the rear for the next few weeks. Could I interest you in posing for them, you would have to be naked for the entire time you would be posing."
"Dear, don't you think you should have a look at their butts and backs before asking them to pose, you may not think their bodies would be what you want your students to try painting. You may only want one or the other, after all they are not identical like Tristan and his Brother."
"You are right. Boys, would you mind showing off your bodies? Although I have heard from some of the assistants in your classes that you natural bodies are nearly perfect I should judge for myself."
Pierre laughed at the woman's forwardness. He had not ever been hesitant about undressing unlike me but as soon as she told us that she was sure she wanted to judge our bodies before having us in front of her classes he grabbed me by the hand and dragged me away from the dining room table. I had never been naked in front of a female before the classes had started and still wasn't comfortable facing a woman with my cock showing. Just Pierre's touch had my cock standing, I was happy when she asked us to turn around so she could see our butts and backs.
"Tristan is it true that you are able to shift into a younger version of your male body?"
I was still holding Pierre's hand when she asked me that. I quickly shifted into the version of myself that I remembered being when I was no older than thirteen. I could have gone younger but I didn't think she would be having her students painting children. I must have been wrong because after praising the shift she asked how much younger I could change my body. I felt insecure standing by Pierre's powerful body but when he nodded at me I shifted to a boy about eight or nine. That brought me almost with my face at the level of his cock, he gave me a smile. I wondered if that was because he would be interested in having sex with the younger me? Especially fucking my mouth?
"Tristan, how young have you ever been able to shift your body?"
"I prefer not to do it in front of anyone but I can shift all the way back to when I was in diapers." I didn't show her that transition, if I went that young Pierre would have needed to pick me off the floor and carry me; I wondered how that would feel.
"Pierre, are you able to shift into a younger you?"
"I haven't been able to do it, yet. I suppose after shifting for a while I might be able to make that shift as easily as Tristan." He had let go of my hand and was squeezing the nipple closest to him.
"I think you would be perfect models. I will be glad to pay you the going rate for models, you would have to stand in front of the class for two hours twice a week for the next three weeks."
"There will not be any classes that you have to attend during the art class time. Lyla is there a problem with them listening to their language lessons while posing?"
"No. Both classes have a few beings from the outer planets so they may even be able to get actual practice while posing."
I hadn't known that painting was still an art form that was being practiced. Most of the images I had seen over the past few years had been digitized so that the FBI or police had a perfect likeness.
"Lyla, I am willing to pose for most of that time but at the end of next week we have a break of three days during which I have been arranging a visit with my family in Morocco. I hadn't asked him yet but I hope that Tristan is willing to go with me and meet them."
Mr. Downing spoke up, "So that is why you have been spending time with the Flovian on the luxury yacht. Has permission been granted for you to take the ship across the ocean?" I wasn't aware that you had put in a request to use it.
"I didn't, the Flovian put in a request to take the yacht out on a training voyage. We will skim the ocean on the way there and return by taking it out of the atmosphere for at least two orbits of the Earth."
"Do you feel like you have been trained well enough to do that?"
"Not yet, but I believe the Flovian will have me trained that well by the time we are supposed to leave."
"Lyla, you have wanted to visit Marrakesh. We should give the boys the days off and travel with them. Pierre, is that where you will be going in Morocco?"
"No, but the Flovian will be able to continue the voyage from where I plan on visiting with my family, it is only thirty or forty kilometers."
I stood there still a young boy holding Pierre's leg. One thing about shifting is that you don't lose any of the memories you have in your natural state. Ever since one of my Mothers had forced Reynod and I to watch Casablanca I had wanted to go to Morocco. As soon as we left the couple's home I intended to let Pierre know I would be happy to go with him to meet his family and visit Morocco. I really would have liked our trip to be set to be longer but at least I would get an idea of what the place was like and get a dip in the Mediterranean.
We hadn't needed money which we were at the clinic or on our two missions. I had thought we were to be paid while at the clinic but I hadn't seen the evidence. Having Lyla pay us for modeling would at the very least give us spending money, I had learned that the yacht was already fueled for a few light years of travel so that would not be a problem. There was also food on the yacht for the thousand slaves that had only eaten twice instead of the planned hundred times. I hadn't spent any time learning much about the yacht so I hoped that the Flovian and Pierre would be able to find enough knowledgeable people to man it on our maiden voyage.
"If you want, I wouldn't mind you shifting back to the last age you were before that." He had whispered it in my ear so that neither of our hosts heard him. I knew we were about to leave so I wondered what he had in mind. I turned away from Pierre to shift up the few years I didn't want him to see that plus the few years I was going to add a few inches to my cock and some thickness just in case he wanted me to fuck him as a teenager. Reluctantly I didn't dress after shifting. What the Hell? Everyone had seen everything I have, why cover up?
"Pierre, I will be happy to meet your parents but not like this. I will be shifted back to my natural state." We were walking back to the room, Pierre had convinced me to stay in the body of my thirteen year old self. I felt insignificant walking beside the man that now towered over me. I hadn't shifted my clothing since the purpose of the shift was for Lyla to decide who she wanted as a model so I was carrying the clothes I had worn to our dinner. We didn't pass many people on our way home but there were enough that I was feeling totally exposed as a person since Pierre was walking alongside me with a hand on my shoulder, then my back and if we stopped to talk down to my butt. He had changed since the first few days at the clinic when he didn't allow anyone know anything about him to this loving man that was willing to allow others see him involved in PDA.
"That is fine for when you meet my Mother and sisters. If we go to the beach to see my Uncle I hope you will be willing to go as the younger you. I don't want you to allow him to take you off on your own but I do want him to be jealous, he is a prolific pedophile that has been run out of the city. When I was growing up my Mother would never allow me to be with him unless she or my Father was with me, even with their protection I remember him getting images of me on the beach naked for his computer. You have commented on how easy I am to convince to shed my clothing, I have been that way ever since we first moved by the water and I was able to go swimming naked."
"Pierre, you should know that even if I shift my age I don't change my brain. My body may be thirteen or seven but my mind is the same as it is before shifting."
"Why are you telling me that."
"I've seen the way you looked at me in both of the younger versions, I could feel the lust exuding from your body before I ever saw your erection. I may be able to give you a young body but my reactions are going to be the same as they have been every time we have been together. What is it that you want to do to my eight year old self?"
"I wouldn't think you would need to ask that. Tristan, I want to pin you down on the bed and force my tongue in your tiny butt and asshole. Once neither of us can stand it any longer I want to fuck that little hole and fill you with the biggest load of cum ever."
"And this body?"
"I think I want to start the same way but the I hope you will flip around and fuck me doggy style. Teenagers can fuck so hard I hope I am able to stand having your cock pound me until you shoot a teen load of cum in me."
"When I was this age I didn't know when to stop fucking. I had just started learning how much I loved an asshole around my cock, I would fuck whoever it was two or three times before stopping. Sure my cock was smaller then but if I fuck you as a teen I'm going to use my adult cock and wear out your asshole." Pierre had loved what I said, he pulled my hand through the waist band of his pants and forced my hand down on his wet cock. I didn't need to ask which scene had made him leak pre-cum, the only times he had seeped before was when I fucked him.
"When was the first time you were fucked, Tristan?" He hadn't let my hand free as we continued walking. I was happy that the only one we met was the Flovian. He and I were almost the same height, I wondered if he felt as small when standing beside us as I did with Pierre towering over me. He promised Pierre that he would be glad to suck either of our cocks on the trip to Morocco if they didn't have any females on board to help run the yacht, he was more forward than he had been on our missions, he stepped up in front of me and took my cock in hand. With me sandwiched between the two Pierre moved his hand and slid it down the crack of my butt and pressed a finger to my asshole. My young body was tight and it hurt when he pushed his finger into me.
"We were headed to bed. I think we will both be glad to have you use your mouth on our cocks on our way across the ocean. If we don't have time to both give you a load we can take an extra orbit of Earth on the way home and will let you suck our cocks again." Pierre moved us away from the Flovian and pushed me down the hall using the hand on my butt to steer me.
"Pierre, you are going to need to use a lot of the lotion to put your cock in my asshole, I am too tight to take you without it." I had gotten used to his finger and although enjoying it knew that his cock would hurt even more. He was trying to get a second finger in me but without any lotion it wasn't going to be possible. When we arrived at the door to the room he pulled out his finger and moved my hand out of his pants.
"Time to shift into the younger you." s The promise of having him sticking his tongue into me was enough to make me follow his order. When we walked in my brother was laying on a bed waiting for us to return.
"Tristan, ts been a long time since I saw you looking like that. What are you doing?" He really didn't need to ask, Pierre had already found the lotion and was getting his fingers greased to open my asshole.
"Pierre, you promised to lick my ass first." I winked at my brother, Reynod had seen Pierre and I having sex but that was going to be the first time he saw Pierre tongue deep in my asshole. He must have wondered what had come over us. As Pierre moved me onto the other bed I had some fear that his cock was going to rip the child me open. I thought about the practice exercise when we were forced to enlarge our assholes but decided that what he wanted was the child's asshole not a sloppy gash where he could stick his whole hand.
I almost bucked him off the bed when I first felt his tongue touch the center of my asshole, I had thought it would feel like it did when I was in my twenty-one year old body but I had forgotten how ticklish I had been as a child. Between giggling and bouncing up and down I loved what Pierre was doing to me. He had started by licking around the tiny hole and soon enough was probing me with his tongue. I tried to last, it didn't take too long before I started to beg him to open my asshole for his cock. I wanted his fingers, during the last few weeks I had grown to love the way he used them inside of me.
Reynod was shocked at how much I seemed to be enjoying what Pierre was doing, he knew that at that age I had never allowed anyone touch me on my asshole or my cock. It wouldn't be until my body aged a few years before I allowed him to give me my first blow job, he had introduced me to the pleasures my cock could give me, also those his mouth and ass would give my cock. If Pierre didn't have me flat on the bed I would have called Reynod over to the bed to suck me.
I had been right, even with a lot of lotion his cock hurt opening up my asshole although having him on top of me felt good. I didn't understand half of what he was saying as he pounded away at my ass, I got the impression that my asshole was the tightest hole he had ever stuck his cock into. As small as I was his cock felt like he had his arm in me, it took at least five minutes before I was able to adjust well enough to spare me any further pain and begin to enjoy him running his cock through my anal ring and opening the other sphincter for the first time.
I hadn't thought about my asshole being virgin when we lay down but as soon as I felt him throbbing and the cum running up the shaft I knew that I would never go without being fucked again. It was a shame that we hadn't actually gone back in time so I would be able to enjoy being fucked for all the years up until I was twenty-one. It was odd to have an orgasm without cumming but at least that meant we wouldn't be sleeping in a wet bed.
"Pierre, I hoped you enjoyed that. I will be willing to shift into this body for you again, I loved it almost as much as I enjoy fucking you."
"Sh. Its time to go to sleep." I thought he meant that it was time for us to be separated but no, he rolled over on his side and held me against him. As we lay there he gently caressed my body from my tiny nipples to my acorn sized balls. I didn't think I could sleep the way he was touching me but it couldn't have been more than five minutes later that I fell into the best sleep I had since arriving at the clinic.
Usually it would take deep concentration for me to shift. I don't remember dreaming or attempting to shift but I woke as a twenty-one year old using the cock in my ass like a dildo and stroking my cock. My movement woke Pierre, it didn't take him long to match my movements, gladly he had moved my hand and was stroking my cock with the same rhythm he was using in my asshole. Soon I was shooting cum on my stomach and his hand and almost as soon as I did he shot in my ass. I hoped that we could wake like that many times in the future, a better thought than any I had ever had with a different man.
Reynod didn't say a word, he came to our bed and licked my stomach dry and sucked Pierre's fingers. I lay there with Pierre still erect in my ass wondering how many times my twins had licked up my cum since he had introduced me to sex. While he was sucking Pierre's finger I felt a hot splash inside of me.
"Oops! Sorry! I need to go to the bathroom." Pierre pulled his cock out of me fairly roughly and rushed across the room to the bathroom not taking time to close the door. Had he pissed in me? Surprisingly I wasn't grossed out at the thought. Hell, would I like him to do that again, the heat was fantastic? I would soon get to know just how hot and fantastic it felt leaving my asshole.
I listened to his piss hitting the metal urinal, it was the first time that I remembered being interested in another man's urine. As I listened I wondered how interested I might actually be. I knew of men that drank piss, of others that pissed their own pants, one that liked having men piss on his head and another that enjoyed having men piss on his balls and asshole. Where would I be in that group? Or was feeling Pierre's piss in my ass as far as I would ever go? I would have to talk to him about it.
I went into the bathroom and joined him at the urinal. Even thinking the way I had been I didn't think he would take my cock in his hand and aim it into the urinal for me. We would definitely need to have a discussion about this. Silently I wished he would aim the piss at his body, his balls or his feet.
We didn't have a class in shifting that day. For the longest part of the day we examined images of the different sentient species elsewhere in the Milky Way Galaxy. Some didn't look too difficult to shift into but there were a few that I wasn't sure I would be able to mimic even after a week of trying. As the class was coming to an end I had to ask, because they hadn't been mentioned, if we would be expected to learn how to shift into a Sphinx.
"Class, there has been a good reason why we have not shown you an image of the Sphinx. The brilliant planet where they live has not signed on to be part of Intergalipol you will not be permitted to function as a member of the organization on that planet so you will not be expected to shift into the terrible beings."
"Isn't their planet close to Cano Zeert? How is it that we won't run into them and need to be able to transition into one of them?"
"Both Cano Zeert and Anubi have established a no fly zone between their planets and patrol it seriously. Your Sphere would be disabled before you entered the no fly zone a kilometer. I doubt you want to be subject to the Canods' punishment, we have not been told exactly what that is but we do know that Canods are the only species that had successfully survived their own punishment. From the reports the Canods gave at the conference establishing which planets will be included in those who may call on the Intergalipol the punishment is one that we would call a War Crime on Earth.
"This is probably a good time to give you a second warning. Unless we have been officially requested you do not want to land on the surface of Cano Zeert. The Canods not only apeear much like the dogs on Earth they have the unfortunate similarity in that the males will try to fuck anything. That may be due to the fact at only males live on the surface of the planet or they could just not care where they stick their dicks and knots. Yes! Just like the dogs on Earth the Canod's cock had a knot that will lock them to whatever they are fucking for more than an hour. As you'll see later this week there are more than one class of Canod, none of them are as small as a Chihuahua, for the most part they are as large as humans and weigh about the same. Their appearance and desire to fuck anything is all they have in common with the dogs on Earth, they are one of the most intelligent species you will encounter in the Perseus arm of the Galaxy.
"For our natural females. Can our species interbreed?"
"That hasn't been determined, the microbiologists are running the tests while you are being trained. The answer will be given you during the last week you are here, you will learn about not just the Canods but every other species we have encountered that we think you may be willing to mate with. They were one of the last species added to the list being studied, that is why there isn't an answer. The scientists didn't think any Earth females would want to mate with a Canod until they were shown some videos of what interspecies mating is like from back when humans generally only had dogs or horses to choose from.
"One more thing about that. We do know they can't breed with the dogs from Earth."
"We didn't miss the class on Intragalactic sex while we were working did we?" I would have been upset if I hadn't had the opportunity to experience sex with some of the beings from other planets, especially the men from Phrotines which we had seen while intercepting the smugglers. Pierre and I had agreed that we shouldn't approach any of them for sex since they had to be traumatized at being kidnapped and being transported to live as sex slaves. Still, neither of us could keep our eyes off of them when they were leaving the yacht on Mars or the couple that had remained with the yacht to join the beings at the clinic.
"Don't worry, Tristan. The three days you will be with the other species is coming at the end of the week. By then I hope that you will be able to shit to most of the species, there are snobs among them just as there are on Earth, some will only have sex with their own kind beings transitioned into their kind are usually accepted as submissive. I had heard that rumor the first time we were told that we would have a few days with other species to explore their willingness and capabilities in a bed.
Even though Pierre had me willingly being submissive that didn't mean I was going to allow another species to mount me. Reynod and I had discussed the possibility of having sex with a Canod or a Phrotine, none of the other species whose images lined the walls heading into the dining room held any interest for me. I told him that but as well as the Flovian had learned to suck cock I had to include him in the species I would attempt to fuck. The first time we discussed the issue Reynod had admitted that he had a odd desire to take a Sphinx to bed and learn how the three different classes of the species joined together when with a man, would they want to fuck, to be sucked or suck? I doubted it would be that simple just because humans were able to join another with only one desire.
"Pierre, you and I haven't ever talked about what we think about having sex with a different species. Or what you think about me having sex with one of them. Do you want to fuck any of them?"
"Tristan, I'm like you. For some reason I have a desire see what sex will be like with a Canod. We should have taken the opportunity to have a Phrotine come to the sphere on our way home from Titan. I saws one of them shift between the beautiful female to a man that I would have let take my virginity before you." All the way through dinner he and I talked about how beautiful the Phrotines had been and how angry the people that were supposed to buy them were not to have the delivery.
