[TSF no F (NOMU)] Welcome to the Succubus Sorority 2 ~Turned into my younger sister's little sister and got a girlfriend~

Newly transformed into a girl, Niita drags herself through the school day utterly exhausted, until classmate Kokoa corners her with the one question she dreads—and rather than exposing her secret, pushes her down to lick and finger her until she's twitching, panting, and begging him—her—to stop. A steamy flashback to the horned, tailed succubus stroking her former male body to a messy finish reveals exactly how the transformation happened and why her new body aches so easily. Between gasped confessions and breathless kisses tangled together on a bed, blackmail melts into something far sweeter, leaving the former boy happily admitting that living as a girl might not be that bad.
