My girlfriend never lets me fuck her without a condom. We have been together for a while and had sex plenty of times, but every hope of finally going raw is killed the moment that thin condom appears. While I fantasize about bareback sex, her busty older sister flashes her tits and offers to let me creampie her. I love my girlfriend, but I cannot resist a stacked woman promising raw sex. Soon I am consumed by the affair and filling her sister again and again. Even when my girlfriend catches us, it feels too good for my hips to stop.
