[Hotaryuso] The Bodysuit (COMIC Unreal 2020-02 Vol. 83)

A curious student answers a too-good-to-be-true part-time listing offering 200,000 yen a day to test a mysterious bodysuit, only to fall into the hands of a bespectacled researcher with far darker intentions. Sealed inside the glossy second skin, her body rapidly transforms against her will—her breasts swell heavy with milk, her erogenous zones burn with multiplied sensitivity until pain and pleasure blur, her clitoris grows into a cock-like nub, and her nipples are forced open into penetrable holes. With the fusion complete and escape forever impossible, she's broken into his first bodysuit sexdoll, drooling and dazed, ready to assist in whatever experiments he dreams up next.
