[CAWD-739] My plain otaku friend is a slutty guy with a premature ejaculation problem, and is extremely virile. She sucks my dick like crazy and shakes her hips in a really lewd way to train me... Shitara Yuuhi (Censored)

At university, she is a quiet girl at the edge of the class. However, Shitara is a geek friend who shares the same hobby of liking erotic novels and can talk to me about anything. As we were casually talking after class, a condom fell out of Shitara's bag. She was embarrassed but made excuses, but an awkward atmosphere flowed... "If you don't mind, I'll use it?" Before I knew it, two geeks with no sexual experience were alone in a love hotel. She seems to be the type who looks thinner when she takes off her clothes, and her ideal body type with plump breasts and a slim waist made me fully erect! The two of them mixed together while exploring each other like in an erotic novel. The blowjob was insanely erotic and felt insanely good! Sex feels so good it's making me go crazy! Shitara, if you shake your hips like that, I'll cum...!! The imagination I've been saving up until now explodes! My plain geek friend was a sex freak who loved dicks. A gloomy, sullen, and plain girl is hundreds of times more lewd and perverted than a flashy, sexy gal with a lot of pheromones. The two girls, unable to suppress their lust, not only at the hotel, but also at their university and home, and they let out their sexual desires that have been building up every day, ejaculating over and over again until they went crazy...
