"I'm going to cum soon!" "You're so good at cumming, Yuzu!" Senpai's long, bony fingers stimulate her in the most pleasurable parts of her body, making her cum even though she wants to break up with him...! --Yuzuka Sometani is dating Alan, a handsome, high-achieving and popular guy. Everyone wonders why Yuzuka, who is rumored to be playing around with guys, is dating a senior. But he has a dark side...!? On a three-day weekend, Yuzuka's senpai came over to her house and say that he is going to "record" these three days spent with Yuzuka. For the next three days and three nights, Yuzuka, who didn't like it, was kept on her haunches and made to feel his hard pistons, and she wouldn't stop coming, no matter how hard she came! When Yuzuka finally asks to break up, senpai's behavior escalates...!
