[TSF no F (Betty)] Okatai Anata o Sukkari Yawarakaku [Guestoid]

Rui doesn't do subtle — the horned blonde with a heart crotch tattoo drags Daiki out behind the school, announces she dumped Yuki, and presses her big breasts against him until he's gasping for her to stop even as his body gives him away. What follows is a sweat-slick ride that leaves the flustered boy completely undone, all while the threat of Shinomiya-san finding out hangs over every stolen moment. By the time Rui purrs her offer of no-strings casual sex from his bed, Daiki never stood a chance — and with a gender-bending twist woven into her devilish charm, staying 'just like this' might change far more than his relationship status.
