My name is Greg, and i'm 15. I'm about 6 foot and have blond hair, but not particulaly buff. I had come in for my Allion's Graduation with my grand parents, since my parents both work. Allison is 18 and very good looking. She has shortish brown hair and a simply unbealivable ass. Her breasts are about a C, but more likly a B.
The cerimony was kinda long so all of us were ready to get out of the Gym. We had to pack up against each other to say together in the crowd, so just to my luck i was right infront of Allison. I was joking around and said, "Well not all of us are going to look as good in a cap and gown as you do when we graduate." This got a nod from her younger sister Jennifer, or Jenn as i called her. This remark also envoked a pinch of my butt from Allison and she said, " Get moving Greg before i have to give you the whole package." This got my pants stirring but i had to keep my cool because Nicole, Allison's older, married sister was infront of me. With that I shut my mouth and kept walking. I got to thinking, what did she mean by "the whole package", but I lost my train of thought i we rode off in the car.
As I was getting ready for bed I faced a large decision. I normaly sleep in my boxers, but since I was in a room with Allison and Jenn only feet away from Nicole and her husband's room, I felt it better to sleep in my clothes should one of them walk in and find it inappropriate. I was talking with Jenn when Allison came in. She had on her school gym uniform, shorts and a loose t-shirt to my disappointment. She climbed between myself and Jenn in the two twin beds we had pushed together , and we started talking about trivial info on out lives, love interests, school, the normal run around. Suddenly, with out me seeing it comming, she snuggled right up against me. Now this was nothing unusual, but the way she was positioned it would make things difficult if I found myself with and erection. But I followed suit anyway and wraped my arm around her (we were laying on our sides facing each other. Her natural scent is very intoxicating and I was finding myself aroused. I tried to think against it but I found this useless, so I'd see if I could roll with it. I got close to her and said jokingly, for cover in case it didn't go to well, "Hey you think Jenn is asleep?" she aswered, "yeah, I think so". With that I said, "Is she a real heavy sleeper?" as I said this i moved my head closer to her's and kissed my way across her neck, which produced what I think was a very soft moan. She answered, "I hope so" while looking my square in the eye. I took the hint and moved my hand down to her sweet ass and gave it a good firm grab, which got us both more excited.
She rushed in and started a long french kiss, which allowed my hands to roam across her trim belly and up to her breasts. When I reached them I found my bigest surprise so far, she wasn't wearing a bra. She was so perky she didn't need one but allways wore one, which made me realize, she planned this! This sent my member straight up, 7 inchs jaming at her. She finally broke the kiss and told me, " My boobs haven't been sucked in awhile". So after giving her nipple a light squeze, when under the blanket and took her right nipple in my mouth, sending a shutter and a moan through her. I worked it with my tounge, giving attenion to the left breast with my hand, causing her to rub between her legs at her clit. I took notice and reached down to slide a finger in her vagina. She was a vigin so she was very tight, even to one finger. After I felt she was bored with the sucking, I kissed my way down to her pussy. I moved her hand out of the way, pulled out my finger, and proceded to eat her like a starving man.
After about a minute or two she had her first orgasm ever. She was moaning like nothing I had heard before, flooded the sheets, my face, and my tired tounge in the process. She restrained herself from screeming, which seemed a very hard task. She finally descided to give my straining cock its freedom and attenion. I had to lift myself up so she could get my shorts and boxers off, so being so close to her face when she pulled down my boxers, my dick sprung out and struck her in the lips. She seemed quite stunned, but recovered quickly as she took it in her mouth. She was able to get most of it down, so I emidiatly began bobing her head up and down my shaft. Wanting not to cum in her mouth, to spend more time down south, I told her to stop and she let my penis go. I rolled her over ontop of me, pulled her shorts off completly, and guided my dick into her virgin pussy.
She let out a squeel, which awakened my fears of being caught. I continued to push in, with her moaning in extacy, untill I hit her cherry. She looked at me lustfully as I pushed through, her only giving a slight hint of pain. I had soon streched her, and was in all the way up my 7 inchs. I pulled out and began pumping slowly. After five minutes of steady pumping, she wispered, "Greg, aaahh, fuck me hard, oooohhh, and fast". I took no time to reply and started humping her harder and very fast, I had to grab onto her ass to keep her from flying off. Her tight walls felt so good as I thrust in and out her. I felt her soon coming to her second orgasm. It hit her like a 18 wheel tractor trailer, she screamed out loud, so loud I had to put a hand over her mouth to muffle her through her orgasm. Her pussy walls convelsing on my cock sent me over the edge as I was seconds from cumming. Then it hit me, I wasn't wereing a condom. I pulled out quickly to her displeasure, and exploded all over her boobs and belly. We both relaxed and I settled her down off of me when I felt Jenn stir in the bed next to us..
