I finally have my first girlfriend and dream of romantic condomless sex, but she absolutely refuses. Even though I see us getting married, all I can do is fantasize about how raw sex might feel. Then her busty older sister flaunts her tits and tells me I can creampie her. I love my girlfriend, but I cannot resist an invitation like that. I become obsessed with her sister’s heavy breasts and bare pussy until my girlfriend catches us. Even then, it feels too good to stop, and I keep pumping load after load into her older sister.
