[Zonda] Fellatio Kenkyuubu Ch. 4 (COMIC Mugen Tensei 2022-06) [Cuddlebuns]

Seishiro-kun's extracurricular duties come knocking at his own front door when his glasses-wearing teacher arrives to collect what the Fellatio Research Department is owed, and she wastes no time kneeling to deepthroat him right under his mother's roof. Once Madoka joins in, the boy's big dick never gets a moment's rest—messy blowjobs, cum-swapping kisses, and a sweat-drenched cowgirl ride in sheer pantyhose leave him completely drained by his insatiable seniors. Spent and unconscious, he still can't escape their affection, as the women coo over his sleeping face and promise they'll be back at it tomorrow.
