[MNGS-064] A super lewd sex friend older sister who drives me crazy now that I have a girlfriend. I was so sweaty and drenched in sweat from a senior in the club (sex friend) that I was so devastated I forgot about her.

Higashi arrives at a regional hotel for an event camp with all the club members. Having just found a new girlfriend, he was spending his days in high spirits preparing for their first date. At that moment, Misono-senpai, the Madonna-like figure from the same club, suddenly calls her into her room to deliver her luggage. I entered Misono-san's room, finished my errands, and was about to leave, but was whispered, "I'm targeting Higashi-kun~," and was forcefully cuckolded as she was. Any man would want to her, with massive squirting, athlete-level cowgirl position... After experiencing sex on a different level from his girlfriend and becoming a casual sex partner, Higashi finds it impossible to get out of sex with Misono-san...
