Cousin’s Night

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.
THAT NIGHT
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.
