[Funabori Nariaki] SeiTenKan ~Hatsutaiken Wa Onna No Karada~ (COMIC Megastore DEEP Vol. 32) [ChoriScans]

Nao's quiet morning is hijacked when two college buddies—Nadyuki and the bespectacled Tonkatsu—crash her apartment with booze, insisting on a pre-drinking session. She finds herself pinned and teased, her newly soft, sensitive breasts and stiff nipples squeezed and suckled as her friends reminisce about her old "orgasm collection" habits. Overwhelmed by the sensations of her transformed body, Nao confesses she's never felt anything this good, while Nadyuki offers to "give her a hand."
