MIAB-545 "If it just accidentally comes out, that doesn't count as cheating, right?" Discussing sex with my girlfriend's super hot little sister, my dick gets toyed with until I'm on the verge of cumming but she won't let me, completely trained in the collapsing pleasure. Amiri Saito

While discussing sex with his girlfriend's stunningly hot little sister, the male protagonist gets teased and toyed with by her in a seductive manner. She deliberately edges him to the brink of ejaculation only to stop repeatedly, keeping him teetering on the edge of shattering pleasure, ultimately training him completely into her sex toy. Using the excuse, "If it just accidentally comes out, that doesn't count as cheating, right?", the sister lures him into sinking irretrievably into forbidden ecstasy.
