Sleepover Fun

Hello, ok heres the lowdown:

I had my best friend and his sister sleeping over at my place becose of it was too hot.

Anyway I was dieing for a wank so when everyone when to bed becose me and the other 2 were in the same room and she had her own room.

So when everyone was asleep I sneak into the room she was in and looked thoght her bag and found a pair of undies.

BINGO!!

Then I found out that she was no complutly under the sheets so i used my Nintendo DS as a light and lefted the covers and put my hand on her ass.

I was soon really horny so I put out my dick (i dont know how big it is) and starting jacking off with her undies on my now really big dick.

In a matter of secs I cumed! i helt it in and put the undies back in her bag, and redid the covers and when and cleaned up.

I soon when back and put my hand on one of her really nice breasts and then when to bed

Enjoy!
