Her best friend, Riho Shishido, spends the whole day whispering and tempting him with a close-contact date where her boobs press against him. With the words, "If it's just a handjob, it's not cheating," she presses her soft, squishy boobs against him and starts a tongue-kissing handjob. One after another, variations of handjobs unfold: a nipple-licking handjob with slurping sounds, a soapy boob-pressing body-washing handjob, and a face-full-of-boobs nursing handjob. The viewer panics, thinking, "Hey...! Shishido-san...! Even this is too much, sex is definitely bad!" But then, tipsy, she unleashes a explosive pounding piston thrust. Even when morning comes, the close-contact spider cowgirl position continues, and she makes excuses like, "Even if we have sex, as long as it ends with a handjob, it's not cheating," while her handjob, with its varied rhythm that his girlfriend can't match, feels way too good.
