My girlfriend never lets me fuck her bareback. Every time I try to enter her, she hands me a condom, killing my mood. I want to have more intense, pleasurable sex, but it never happens. But her sister is different! She has bigger tits than my girlfriend and a body that feels even better in my arms. She tempts me by saying creampie is okay, and I find her way more erotic. I love my girlfriend, but I lost all self-control when faced with my long-desired bare pussy. I got carried away having sex with her sister—until my girlfriend caught us. But it felt too good to stop, so I couldn't pull out. In the end, I creampie'd her sister right in front of my girlfriend.
