My wife used to go visit our daughters at college a couple of times a month. It took me a while to discover what they got up to together. I didn't like them doing it on my dime, so I gave them the freedom to do what they liked in the future. A flash BTB story, no sex.
When his roommate and fuck-buddy Cassie sends him a picture of a hot blonde with big tits and asks if he's ever seen her, he recognizes her as the girl who was trying a little too hard to pick him up the night before. Turns out Cassie pissed the girl off, and she's a well-known serial homewrecker. Cassie has a deliciously evil plan to teach little miss Mercedes a lesson, and Jeff is all in.
