I got to Dave's apartment about 7, he was in the shower washing off the sweat and grease from this afternoon. We had been working on his sister's car, well we were not just working thats how we got caught. His little sister peeked on us and now she wanted in. While Dave showered I put a porn in the VCR and rolled up a couple joints for latter. Tammy came in and when she and saw what I was doing she went in the kitchen and got some 3 cold beers. As Dave came out of the bathroom Tammy held out a can he grab a beer then said.
" I can't get my 10 year old sister high."
Tammy kicked him right in the ass. " I am not 10 you asshole. I'm 15, I've smoked pot before, and I have bigger tits than Mom."
I said " Prove it."
When Tammy pulled off her sweatshirt my jaw on the way down hit my dick on the way up. They were perfect. How could I not have noticed how much she had changed in last year or two. Dave must have been thinking the same thing because his dick was as hard as mine.
"I'm sorry. I see you have grown up more than I thought; but are you positive you want to do this we could just play cards or something."
" I want to try allot of things but I don't want to get a rep as a slut. This way I can see what sex is like and nobody will tell. I've had a crush on Mike since I was 7 and I love my brother, how could it be wrong?"
"If you're sure you know what you're doing, who am I to complain." I chimed in.
Tammy took off her skirt and shoes leaving only her little pink panties. My hard on sprang in my shorts pitching a tent the circus could use. I may be a pervert and a cocksucker but I'm not gay. Dave dropped his towel and sat down on the couch. Tammy gave a whistle and winked at her brother in a fashion that no mother would approve of.
" Sis, If you like mine wait till you see his."
She turned to me. "I'll show you mine if you show me your's."
I pulled down my shorts and underwear at one time so the strain would not kill me.
" You weren't kidding were you. I was afraid you didn't like girls when I saw you two in the garage today. I hoped I could change your mind."
I could not wait any longer, I took her in my arms and kissed her. We melted, the passion growing as our tongue locked all of the sudden Dave whispers in my ear.
"That's my sister you know."
She looked up at him and said " Does that mean you want play with your little sister?"
"Your not little anymore."
Tammy took his dick in her hand and said.
"Your getting pretty big yourself."
I kissed her ear and said.
"It tastes better than it feels."
"When I saw you two in the garage today I was worried that you gay. I'd still love my brother anyway but if the guy I've loved since first grade was gay I'd die. That's why I pushed you into this, so I'd know for sure."
"I'm not gay I just like sex. I could never love a man but I do enjoy sex with Dave. " I said.
Tammy turned to Dave and said. "I want Mike to take my cherry I've thought about that since I learned to play with myself then he can teach me to suck your dick like he does; it looked like you both enjoyed it."
"I'll sit here smoke this joint; but if my balls explode I'll never forgive you two."
We laid on the couch and explored the others body with our hands. I moved down her body till I could wait no longer . I had to taste her. Her body shivered when my tongue touched her clit and a gaps left her lips. Honey , her pussy tasted like honey and I licked like a bear storing fat for winter. I knew if I didn't fuck her now I would cum on the floor. When my dick began to enter her she opened her eyes and looked deep into mine.
" I love you." She said her voice thick and husky.
I froze not knowing what to say.
" I love you, you don't have say it back I just had to tell you. I've felt this way for years and I wanted to do this with you. Please make love to me."
I did. I really did. We had always kidded around and cut up but I never really thought of her as a women; now I felt something more than lust. Her pussy began to spasm and I lost control. You know how when you cum really hard and things go dim. I went blind. My soul poured out the end of my dick and into her and she held me as if she might fall off a cliff.
Dave said " That was beautiful. I could see sparks between you."
We had forgotten Dave was even there. He was sitting back in the chair with his cock pointing at the moon.
"Show me how to give my brother some relief that thing looks painful."
I told her to hold it in her hand and lick the head like an ice cream cone thats melting in the sun. She smiled at me and started to her task. Dave whimpered like a puppy. For a second I was jealous then I realized how stupid that was now I had both. She took the whole thing down her throat.
"You said you never did this before how could you swallow it all the first time?" I asked a bit surprised'
She blushed when she told us.
" Becky and me practiced on carrots at camp this summer. We were playing truth or dare and talking about boys and stuff. She told me she had seen her folks doing things late one night and it made her feel funny between her legs. She said her mom sucked her daddy's dick and we decided to see what it was like. When she told me about her dad fucking her mom I put the carrot in my pussy. Becky did hers too and we masturbated while she told me what she saw them do."
"Becky with the cute freckles? I wish I could have watched that." Dave said'
"I'll suck Dave and you tell us all about it." I said.
"Only if I can swallow his cum like you did."
When I nodded my agreement she began her story.
"We started to get into it and I offered to pump her carrot if she would do me next. She promised so I started to play with her pussy while she described her parents sex in great detail. I pumped faster as she told me about her daddy fucking faster and faster. She came. My turn I told her so tell me more while you do me. She turned bright red then said she would show me what her dad did after he fucked her mom. She told me he licked the cum back out and her mother cried it was so good. That was all I needed to hear I let her eat me and I liked it."
"Did you return the favor?" Dave asked.
"No not then but after I tossed and turned all night dreaming about it I did. So I guess I'm bi too"
She swallowed his dick again and the talking stopped. I got on the floor and licked his balls. When Dave came in Tammy's mouth she kissed me and we shared it. I knew my life just got much better.
