"It's not cheating if we don't have sex, right?" Even though my girlfriend is nearby, she tries not to get caught by french kissing, sucking my dick, sucking my balls, licking my asshole... This slutty older sister who loves to lick and seduces me with her overly bold dirty mouth play is too dangerous! Before I even consider whether she's cheating or not, if she sees me doing this, I'll be in big trouble! Sadly, it's a man's nature to get a sloppy erection even in such a dangerous situation... I'm teased until I lose my reason, and in the end I want to have sex, and that's it! Thrill is the best aphrodisiac!
