My girlfriend never lets me fuck her raw! Even after dating for so long, condoms are a must! I'm starting to lose interest. But her sister, with her huge tits and no bra, came onto me! I still like my girlfriend, but her soft-looking sister's tits make me waver! And when she says it's okay to go raw... I can't hold back anymore! I seize the moment and fuck her sister senseless! The thrill of betrayal is intoxicating! I can't stop creampieing her when my girlfriend isn't around!
