It had been quite a while since my "performance" over at Mary and Dave's house (see the previous story). I was quite surprised when Mary called me for coffee one day to share an idea with me. "You see, Kari, it's Dave's birthday coming up, and I want to do something very special for him," she informed me. "What's on your mind, Mary? What do you think he would like?" I responded.
"Well, ever since that first time he saw you naked at our place, then when you went down on me -" Mary started. "And?" I urged her on. "He really wants to see you and me together again. Actually, I think deep down he wants to fuck you too, but he hasn't said that," Mary giggled. "What do you want me to do, Mary?" I asked (innocently, of course).
"I thought you might come over and we could give him a surprise treat that he will never forget!" she exclaimed. We started planning things then and there. I had never ever considered being a birthday present for someone, but that changed quickly. It was quite exciting to plan the night, and I was anxious for the day to arrive. I won't tell you the details in the planning, and some of the crazy ideas we thought of, but I will fill you in with the actual events.
Mary and Dave went out for dinner, and while they were out, I used the key Mary had given me to get into their home. Mary had ordered me what she wanted me to wear from Victoria's Secret - a short lace up black slip and lace up 4" ankle strap open toed sandals (a very naughty looking combination). I was going to wear the matching thong panties, but it was just one more line showing through the laced up sides, so I thought I wouldn't bother. It was very sexy looking, because from either side you knew there was nothing underneath. You could see skin all the way up from the hem which was just below my ass. The slip was rather low cut at the front, and showed off a good amount of cleavage.
Mary called me on her cell phone to let me know they were on their way home. I got a bottle of wine ready, lit some candles, turned on the gas fireplace and put on some soft music. The setting was perfect! All was ready. I went into the bedroom to wait.
I was getting a little anxious waiting, so I thought I should do something to keep me busy. It didn't take too long to think of something, because in Mary's bedside table was her vibrator. "Well, why not get started?" I decided. I certainly was dressed and ready for it. I sat on the side chair in the bedroom, licked my fingers and went to work! I positioned myself so that I could see myself in their full length mirror. I don't think I had dressed so provocatively before - I had never worn lace up sandals before and they looked so sexy! In combination with the mini lace up slip well, you get the picture.
I was really enjoying myself when I heard Dave and Mary come in through the front door. Dave was rather surprised to see the fire and all, and I could hear him asking Mary what was going on. Mary kissed Dave and told him that it was a birthday surprise and to sit and pour some wine. "Who is the third glass for, hon?" he asked. "Ha, you will find out soon enough," laughed Mary. "Sit and be patient!"
Now Dave had no idea what Mary had planned, which made it even more exciting. Mary opened the bedroom door, and wasn't prepared either for what she would see - me with one leg up on her bed and the other over the chair arm using her vibrator on my clitoris. I didn't stop as she walked over to me, bent over and kissed me deeply on the lips. Our tongues clashed while I started to use the vibrator as a dildo. "I guess I don't have to ask you if you are ready," Mary whispered after the kiss. "I want to cum now," I managed to stutter, pumping faster and faster. "Hold on, Kari, remember our plans," she said firmly. I sighed and stopped pumping. "Okay, okay, but we have to hurry!" I whimpered.
Mary got out of her evening dress and put on an identical strap up slip and shoes as me (except her slip was a couple of sizes smaller). I told her I decided not to wear the panties, and she agreed that she wouldn't either. "Ok, let's do it!" she ordered. Mary walked over to the door and went out to Dave. I heard him whistle when she walked out. "That is so hot, hon," I heard Dave say. I peeked through the door and watched Mary go over and pull Dave up from his seat. They embraced and kissed passionately. I watched while his hands went up and down her sides, then he placed them just below the hem of her slip and ran his hands up under the slip, over her ass. It was very sexy and romantic watching them. I think for a minute Mary forgot about me. Mary's hand dropped down to rest upon Dave's crotch, and I could see her gently rubbing and caressing what was becoming a very hard cock. "This is just a warm up, sweetie," Mary whispered in his ear. "Now for the real surprise!" That was my cue. I put the vibrator down (with a sigh - I had some unfinished business to attend to) and slowly swung the door open. I stood provocatively in the doorway, and said as sultry as I could, "Happy Birthday, Dave." I thought for sure he was going to fall over when he saw me! "Sit down, now sweetie," Mary ordered her husband.
She reached out for me and I took her hand. We drew each other close. Now, it was Mary and I in a passionate embrace just like I had watched them a moment earlier, and we were continuing our kiss from the bedroom. Now it was my hands roaming up her sides, then under her slip. Soon she was doing the same, reaching to squeeze my ass. I was so involved with kissing her it totally surprised me when I felt her finger press against my anus. I could feel the pressure, then she withdrew. Before I had a chance to react, her finger was pressing again, this time harder, and deeper. I have such a sensitive anus, I thought I would cum rightthen and there. My legs started getting weak, and I felt like I would crumple to the floor.
"Dave, Kari needs you! Get over here," ordered Mary. She told him to stand beside me so I could hold on to him. I put one hand up on his shoulder and he put an arm around my waist, while Mary dragged over a small foot stool. I raised one foot up on it, giving Mary total access to my pussy and my ass. She kneeled in front of me, right in front of me. With my one leg up, there was nothing hidden, nothing that she couldn't see or touch. She gently stroked my wetness. What in fact she was doing, was lubricating her fingers with my own juices! With her now wet finger, she reached through my legs and up to my anus again, this time, steadily working her finger into my hole. With her other hand, she started to manipulate my clitoris, soon replacing her fingers with her tongue.
While this was going on, I managed to look into Dave's eyes. It was like they were on fire! With his free hand he cupped my face and kissed me. His tongue was exploring every part of my mouth. I didn't know what to concentrate on - the finger pumping up my ass, the tongue devouring my clit, or the tongue in my mouth! To make it more difficult, Dave's hand dropped to my shoulders, and pulled down the straps of my slip. He held on to my hand so I could free myself of the slip, and it dropped down to my waist. Now his hand was exciting my breasts, one then the other. The intensity was unbelievable!
My nipples were as hard as diamonds. Dave's tongue was still working over my tongue, and now his hand was manipulating my breasts. Mary was still at full speed with both her tongue and fingers. I was hanging on to Dave as I exploded. The whole room started to spin as my body shook violently. I think my hips were rocking so hard that Mary was having a really hard time keeping her tongue and fingers where I needed them to be, but somehow she stayed glued to me. I cried out in ecstasy - not only did my body come unglued, it was like all my emotions poured out too. I actually started crying and buried my head into Dave's shoulder. He and Mary were changed quickly from getting me off to caring for me but I was okay. In a minute I was laughing. They were both concerned for me, but I was fine and ready for more. I took a big sigh and reached for a glass of wine. "I need to sit for a while," I managed to whisper. By this time my slip had fallen off totally, and I walked over to a chair and sat down, still in my 4" heels.
"That was great, guys. But, now I think it's my turn to watch," I suggested. Dave and Mary looked at each other, and quickly obliged. They walked hand in hand over to the couch, and Mary pushed Dave down. She straddled him and sat in his lap. I watched while Dave lifted off her slip, and then while she took off Dave's shirt. It wasn't long before Dave was totally naked as well, and Mary was riding him. Every time she bounced up, Dave licked one of her nipples. I could tell it was driving Mary crazy with desire. Her hands were on his shoulders and his were on her waist, guiding her up and down on his cock.
Dave was doing a great job of holding back, because Mary was in no rush to climax. I was really enjoying being an observer, but you can only watch for so long - I had regained my composure and was ready to join in. I walked over to Mary and stood behind her. I reached around to hold both of her breasts while she was bobbing up and down on Dave. She turned her head so I could catch a kiss, and I whispered in her ear, "Cum, baby, cum!" Mary mumbled out an "uh huh" and closed her eyes to concentrate. Since I was giving Mary's breasts attention, Dave's hands were free. He reached for her clitoris and started to play with it while she was still riding him. That did it for Mary! She started bucking wildly as it was her turn to explode.
Dave couldn't hold back any longer, and as Mary was coming down from her high, Dave grunted and pounded hard into his wife. Both Mary and I watched with excitement as he let loose. Mary gasped as she felt his eruption inside of her. They both slowly came down from their joy ride, and Mary collapsed into his arms. I reached over and touched Dave's face and said, "Happy Birthday, Dave!" He grinned and said, "Thanks for the present, Kari - but now I want my present from Mary." Mary and I looked at each other, and giggled. "Let's all go into the bedroom. I have a friend in their I want to show you!" Dave looked at me a little funny, but when we walked in, there on the bed was the vibrator I had been using before. "Ok, it's my turn now! Dave, sit down," I said slyly, as I lay on the bed with vibrator in hand. "Now Mary, let's show Dave how we use this!"
