Boku ni Harem Sefure ga Dekita Riyuu - Episode 1

Anon, an introvert with a hidden panty fetish, encounters several female classmates who visit his apartment. After discovering pornographic media, he is pressed into becoming a sex educator for them, leading to a foursome that begins with kissing. The girls then proceed to orally pleasure him, stimulating his penis and breasts while Anon reciprocates by touching their nipples. The scene progresses to involving Mio, the aloof girl, whom he begins to orally stimulate. As she becomes increasingly aroused, Anon gropes her breasts and touches her down there. Anon then penetrates Mio's virgin vagina, allowing her to have her first sexual experience as he ejaculates inside her.
