One day, I happened to glance back on the stairs and accidentally caught sight of Hongo Ai having sex—the girl I'd always admired. Since then, she's been flashing me panty shots, teasing me with her breasts, and showing me her sex scenes every single day. She seems delighted whenever she notices I'm aroused, but for some reason, she never lets me go all the way. Even though it should be infuriating watching the girl I like getting fucked by other men right in front of me, once again today, I can't stop leaking pre-cum.
