After getting caught cheating, I was ordered to abstain from masturbation and had to stay at my girlfriend's house under her watchful eye. But while she was away, I couldn't help but sneak in some solo action... That's when her sister, Akari, walked in and, seeing me, started teasing my nipples and cock, saying, "You're so unsatisfied, seeing this just makes it worse!" She took my cock in her mouth, then rode me doggy-style without a condom! Oh man, that feels so good! Her hips are grinding against mine, I'm about to cum! But then she pulls out and gives me a blowjob instead! For five days straight, I was trapped in an endless cycle of blowjobs and raw sex, all while Akari kept me from coming.
