Boku ni Harem Sefure ga Dekita Riyuu - Episode 3

The episode introduces Nishi-kun, a perverted student obsessed with his English teacher, the yoga club adviser Tanijiri-sensei, whose large, soft breasts he dubs "slime titties." When his friends Megu-kun, Mio-kun, and Rina discuss their mutual interest in the teacher, the group skips gym class and sneaks into the secluded women's locker room to engage in group fondling and groping of their breasts and buttocks through gym clothes. This sexual frenzy leads to a four-way kiss where the girls surround Anon, who has hard cock, and Mio smoochs his dick, imitating pornography. While peeping at Tanijiri-sensei change in a locker, Anon is caught and trapped in the locker with his friends. The group's sexual acts escalate dramatically as Tanijiri-sensei begins sucking Anon's cock, and the friends sandwich him with their butts. The episode culminates in a grotesque sequence where Tanijiri-sensei masturbates Anon with her breasts, giving him a titjob, and subsequently receiving his cock in her pussy. The other girls then take turns inserting and stroking his cock into the teacher's cunt.
