Jess' sister

[RandomName]

This is a story from when I was a teenager, my best friend Jess used to have our friends round her house all the time, and her younger sister used to be there most times.

Jess used to pick on her sister in front of us, especially if there were boys round.

She wedgied her a few times, lifting her up in front of us, which sometimes exposed her sister's buttcrack.

Once when it was me, Jess, and our 2 guy friends, Jess' sister came into the living room. When she was talking to me and the guys, Jess pranked her by grabbing her jeans and pulling down. She looked pretty embarrassed having her legs exposed like that, and her panties even shifted a bit too.

Luckily for her they only came down an inch or two, which showed a bit of her pubes off in front of us.

I was secretly glad for her, 'cos it would have been totally humiliating for her if her naked crotch revealed to us.

The worst time though was when we were all in Jess' pool.

It was me, Jess, our friend Katie, 3 of our guy friends, Jess' sister, and two of her friends.

Jess played a really mean prank on her sister, and basically came up behind her while she was facing us, and held her arms.

Her sister looked worried as Jess held her arms, and then looked totally red-faced when Jess decided to pull her bikini top down.

We could all see her little boobs, even the guys. I felt bad for her 'cos Jess still held her arms, giving the guys an unobstructed view of her small a-cup tits.

I'm glad I'm not Jess' sister to be honest.
