She had always said she'd never let me fuck her bareback. We were getting married soon, but she insisted no creampie until after we officially registered the marriage. However, her older sister started seducing me, flaunting her big tits. And her temptation was even stronger—she was completely okay with bareback sex. I love my girlfriend, but how could I possibly resist such a gorgeous, horny woman? The thrill of possibly getting caught, combined with the intense pleasure of creampie sex I could never have with my girlfriend, drove my excitement to the absolute limit. In the end, we were discovered—but right in front of my beloved girlfriend, I kept thrusting hard and deep. It was the most intense, unforgettable experience ever.
