My girlfriend never lets me have bareback sex and insists on condoms every time. While I fantasize about how good raw penetration would feel, her busty older sister shows off her breasts and offers to let me cum inside. I surrender to the temptation, bury myself in her tits, and lose control during my first bareback creampie. We keep sneaking around until my girlfriend catches us, but even then my hips will not stop—I fuck her sister in front of her and fill her with another huge load.
