How that business trip ended

The proverbial situation got a new twist here with our guy, his stepbrother, and his sex-crazed girlfriend. The bitch wasn't getting enough fun, so here's what she did. While the guy was on a business trip, she brought his stepbrother around. Does not take rocket science to guess that they spent the entire time getting it on like there's no tomorrow! Here's the boyfriend, exhausted, and what does he see? The two bastards seem to be just in the middle of it! What a fantastic welcome home present, bitch!
