Natsu no Owari no Kokuhaku ~Osananajimi, Onjou Shizuku no Baai~ The Motion Anime

Her older classmates call her "the quiet girl next door with big breasts”: a short girl, but already curvy like a woman. Shchyu and I are "just friends,” even though everyone around us knows I’m in love with my childhood friend. In the summer, she signed up for the pool where I go to train, hoping that I would finally become more than just a neighbor to her—that I would become her actual boyfriend. I kept my distance, and one evening, after I was rude to her, she ran off to the park, where she cried on a bench. Our temporary coach, Savamura—a handsome, confident older man whom the girls in the stands whisper about—happened to stop by. He comforted her, took her to his place, poured her some sweet tea with a pill, and that night my girlfriend was brutally raped, and she didn’t resist: moaning, her virginity taken on camera. Since then, after every swimming lesson, Shzhu stays for "extra practice” in the coach’s room: secret sex lessons that turn her former feelings for me into a habit of orgasms and semen on her tongue.
