My girlfriend always insists on using condoms and never allows bareback sex. Even though we've been together a long time, she still won't let me go raw... I'm desperate for unprotected sex. While I truly love her, her older sister started getting close, flaunting her big tits, and tempting me with creampie access. I care about my girlfriend, but her sister is aggressive, sexy, and I couldn't resist the temptation. Filled with thrill and guilt, my excitement peaked. Seizing the chance, I fucked her hard and got caught by my girlfriend—but it felt so good I couldn't stop and ended up filling her sister's pussy with my creampie.
