Mahiro's Female Transformation: Lewd Breeding & Vaginal Birth Doujin - Onii-chan Parody

Nagumo Ryuichi unleashes pure erotic madness as Mahiro's petite body is transformed into a breeding factory, her glasses fogging up while scientists pump her cervix full of seed. The 26-page climax shows her spread-eagle on the delivery table, screaming through orgasmic contractions as a thick infant crown stretches her ruined pussy. Every panel drips with perversion - from the DILF's monstrous cock bulging her pregnant belly to the gush of afterbirth soaking her thighs. This doujin perfectly blends lolicon innocence with raw, obstetric filth. Fans of Neko Lingerie Mahirochan will adore seeing her tits swollen with milk, begging for more cock. Don't miss the 103 English Version for equally depraved lactation scenes. Mahiro's transformation from shy boy to cum-dumpster mother is the ultimate gender-bend fantasy!
