The photography club struggles to attract visitors to the school festival every year. Their advisor, who has a penchant for the sex industry, says, "When it comes to photography, it has to be photos of girls being chosen for a soapland. Listen, a soapland isn't a place where you do naughty things. It's just a 'private bathhouse,' like a public bath! It's a place where the female staff who wash your body and provide services happen to fall in love with the male customers!" This statement gets everyone excited. The super-serious vice-president, Ruka, practices giving a blowjob with a giant dildo the day before the school festival. She practices grinding, rolling, and pounding in the cowgirl position, while also practicing her moans, fully prepared. On the first day of the school festival, their advisor, Kita, comes to check things out and can't resist Ruka's sexy body, so he chooses her. Starting with a blowjob in a sailor uniform, then in the seated position, intense pounding, and a cumshot inside for the first round! She changes into a sexy sailor uniform, and after some slippery lotion play, she gets another cumshot inside in the intense cowgirl position! On the final day, Ruka and Yuno subjected the club president, Goto, to a soap play session. They started with a blowjob in their school uniforms, then switched to cowgirl position and immediately gave him a cumshot. After changing into erotic sailor uniforms, they subjected Goto to a slippery lotion ******* session, driving him into agony, and then finished off the school festival soap play with a deep cumshot in the missionary position… Ruka, the vice president, was as serious and naughty as ever… The erotic girls in school uniforms immediately gave blowjobs, handjobs, titjobs, and cumshots, getting their vaginas thoroughly stirred up and experiencing nonstop orgasms at the school festival!
