stall sneakage

When at lunch your friend escorts you to the bathroom and as you go in the stall she stealhily sneaks in with you. Resulting in hot passionate bathroom sex. Of course this only works with lesbians...unless it's a unisex bathroom?

Jennifur had been checkin me out alll day so I wasn't surprised when she used the stall sneakage attack to get inside my pants. It was all good til we fell into the toilet...
