I should probably start with some background information. The story that I'm about to tell you takes place at my grandmother's house. My name is Joe, I'm exactly six foot tall, I'm quite slim and I'm a decent athlete. I've been a rower for about five years now. By the way, I'm twenty years old.
This story also involves my 65 year old 'Nan', Jill, who is a little over five foot, but unfortunately after a car accident two years ago (in which her husband was tragically killed) she broke her hips and gained a lot of weight; and my 18 year old cousins, Jessie and Lizzie, who are twins. They are identical with long, deep red hair, pale white skin and terrificly slender figures. They also have decent and perky 36B breasts.
The story begins one day when I went over to my Nan's house to check up on her. I let myself into the bungalow with the key she had given me and I proceeded to the living room. I walked in to find nobody was there. I was just about to turn around when somebody jumped onto me.
"I've got him Liz, jump on him while he's down!"
I realised that it was my cousin, Jessie, just as her twin sister pounced on me.
"Hello mister," she said in a playful mock anger, "what do you think you're doing coming in unannounced? We could have been doing anything in here!" With that she winked and I could have sworn I felt her rub her crotch against mine.
"I'm very sorry miss," I said, smiling and playing along nevertheless, "I thought it would only be Nan that was in."
She kept rubbing against me and I could feel myself getting hard. I decided I had to get out from under her before Jessie noticed how aroused her sister was making me.
"If you'll excuse me," I said while making a move to get up, " I'm getting a bit uncomfortable..."
As I got up, so did Lizzie, and she looked straight at my crotch and laughed,
