A true story, my first sexual experience…with my sister.
I was asleep one night and my eighteen year old sister was in our living room watching television, I don’t know what woke me but I lay awake listening to her move about the apartment. My parents where on vacation and I couldn’t tell what she was doing. With my eyes closed but just open enough to see, I watched her look in my room several times.
Then she came in obviously trying to be quiet and knelt by my bed. I thought she was going to try and scare me or pull some stupid joke but instead she slowly pulled down my blanket and just looked at me. Then she carefully began to rub my cock through my jockey underwear.
I almost jumped but stayed still. She rubbed it lightly tracing my cock with her fingers. In seconds I had a raging hard-on. She lightly rubbed my balls and pinched the head of my cock, I thought I was going to cum. I was fifteen and had discovered my sexual desires a long time ago but never thought my sister would do this.
I always wondered why my friends would ask if I had ever seen my sister naked. As she rubbed my dick I began to think about how she looked. I had never seen her nude but she had big tits and a big round ass. I had once looked at her bra’s and she wore a thirty-six D brassier.
She pinched the top waistband of my underwear and pulled it down. My cock popped out and I heard her gasp softly. At fifteen I was hung and almost laughed at the thought that my sister was looking at my cock.
She wrapped her fingers around my dick and rubbed it. Feeling my cock and balls was the best thing I can remember. She continued to rub my dick until I let out a moan which I just couldn’t stop.
Hearing me, she put my underwear back and left.
For the next several weeks I couldn’t help but stare at my sisters tits and ass every time I got the chance. One morning she awoke wearing a sheer nightgown she had bought. My mother had told her it was almost see thru and told her not to wear it.
But my sister did and as I ate my breakfast she came in the kitchen and I almost jumped seeing her form through the material. With my parents at work she walked around the kitchen and I could clearly see the outline of her big tits and a dark triangle between her legs.
Mind you this was the seventies and women didn’t trim or shave. I could see her nipples and when she turned, the crack of her ass. I finished my food and went in my room and jerked off.
A month went by and my parents went to a retreat for the night. My sister knowing this went out with her friends and got drunk. I was up when she came home at two AM and watched her go in her room. I waited about an hour and quietly moved down the hall to her bedroom.
My parents didn’t allow us to lock our doors and quietly I opened her door and looked in. She was on her back under her blankets asleep.
I figured if she could feel me up I could feel her up as well. Carefully I pulled down her blankets and could see she was wearing a bra and panties. I couldn’t get her bra off so I rubbed her tits through the lacy material. I almost came in my shorts feeling her firm tits. This was the first time I had ever felt a tit and was amazed how rock hard her breasts where.
After a few seconds I could feel her nipple, hard, poking against the bra. I rolled it between my fingers and couldn’t help myself. I peeled the bra down as best I could and gazed at a half dollar size dark brown nipple.
I knew if she awoke I would be in serious trouble so I moved down to her panties. I was in luck because her panties had ruffles on them so I grasped one and pulled the front down. Her room was dark but I licked my lips seeing a thick brown bush.
I ran my fingers through the hair and slowly pushed my finger inside her. It didn’t take long before my fingers where soaked. She lightly moaned and like she had done to me, I replaced her underwear and left the room.
I licked and smelled my fingers in my room and jerked off like there was no tomorrow.
For the next several months I continued to go in her room when she would come home drunk. I would feel up my sister going as far as licking her cunt, sucking her nipples, and jerking off in front of her and smearing some cum in her mouth.
My girlfriend and I already when to Haulover Beach together and loved it. When her two girl friends came to Miami she insisted that we all go together. Of course I said I was down but I played it cool and said only if you're okay with them seeing me naked and me seeing them naked. She said, "Of course I'm okay with it! You're all my best friends!" Her friends said, "Okay but we need to pregame and get a little drunk first" 
All 3 of them were shaved or waxed smooth. They said they always look "presentable". The shorter one had her clit hood pierced and I told my girlfriend she should get one of those too! She actually did eventually get it pierced. The shorter one complimented me back and said, "We can see why (my girlfriend) talks about your cock" as they got to see it go from small to fully hard. I apologized but my girl said, "Don't apologize!" and gave it a squeeze in front of them.
