[TSF no F (Betty)] Okatai Anata o Yawarakaku (turn the hardness of ♂ in you into the softness of ♀) [Kuraudo]

Rui's life is turned upside down when the playful demon Lily transforms him into a soft, busty girl, then pins her down to prove that fingers buried knuckle-deep in a brand-new pussy feel far too good to resist. Between Lily's eager tongue lapping at her slick folds and fanged grins promising more, Rui demands to be changed back—until Lily reveals the truth: the scent of men is now what sets her body ablaze, and a locker room crowded with oblivious guys is exactly where she belongs. A gender-bending corruption fantasy where denial melts into mind-melting pleasure and one transformed girl takes on a whole group of hungry men.
