Popular actress Mari Natsuki x Princess River Yuna's debut collaboration work! A school for private fellatio where only the best at fellatio who love cocks gather, showcasing techniques in a fellatio battle! One sucks on the balls while another deepthroats the glans, deepthroat from the front while licking the anus from behind... Anyway, using tongue and mouth techniques to make men feel good, ejaculating large amounts of semen directly into the mouth! If you're sandwiched between schoolgirls doing a double fellatio, you won't be able to hold back and will explode!
