My girlfriend never lets me fuck her bareback... I was hoping that, after so long apart and with both of us turned on, she might finally allow it. But she shut me down—her resistance felt like a knife in my chest. I was already fantasizing about the incredible feeling of bareback sex, my cock throbbing with desire, when her older sister appeared, flashing her big tits and openly inviting me to creampie her. I love my girlfriend, but I couldn't resist the temptation of her big-titted sister offering creampie sex. I got caught up in the affair, fucking her bareback, and before I knew it, I was cumming inside her repeatedly. Eventually my girlfriend found out, but I was feeling so good I couldn't stop thrusting.
