START-416 Escape Condition: Face 5 Delayed-Ejaculation M-Men, Master Ejaculation-Edging Techniques, and Make Them Cum Consecutively! 】The Ejaculation Dungeon You Can’t Leave Until Everyone Has Climaxed — Ichimiya Rui

A palace maid named Rui is trapped in an ejaculation dungeon and must use her exceptional oral skills to make five premature-ejaculating masochistic men climax consecutively in order to escape. Kneeling before them, she skillfully wraps her tongue around their massive shafts, deep-throating until her throat spasms, forcing each of them to erupt thick loads of semen until all five have been completely drained.
