Mahiro's Forced Impregnation & Vaginal Birth - Onii-chan wa Oshimai 18+ Doujinshi Fuckfest

Nagumo Ryuichi’s masterpiece violates Mahiro Oyama in every hole as scientists document her transformation from virgin to cumdump. Her pink pussy stretches around monstrous shafts, screaming through forced orgasms while cameras capture every drip of semen flooding her womb. The 24-page climax shows Mahiro’s pregnant belly rippling with contractions, her cunt spreading wide to push out a glistening infant as perverts jack off to her agony. This isn’t just hentai – it’s a breeding manifesto where Mahiro’s gender-swapped body exists solely for impregnation. Her lab coat hangs open, nipples hardened between violent gropes as she cums uncontrollably from vaginal birth trauma. Fans of Asahi’s first-time deflowering will cream over this relentless seedfest. And when Mahiro’s ruined pussy gapes post-delivery, begging for another load? Pure fucking poetry. Explore more depravity like this sibling corruption tale where innocence dies screaming.
