My girlfriend only allows sex with condoms and absolutely refuses creampie. However, her older sister is surprisingly different—she's erotic, gentle, and totally okay with creampie. Not only that, she has big tits and an amazing body. Even though my girlfriend is right there, I get seduced by her sister, repeatedly doing blowjob, titty fuck, and sex with her. When she tells me creampie is allowed, I can't resist—the thrill of possibly getting caught by my girlfriend, combined with the pleasure of creampie I can never have otherwise, slowly draws me in. In the end, I experience a massive creampie right in front of my girlfriend, creating an intensely thrilling climax.
