[Yajirushi Key (Meito)] Inma-tachi no Yuugi Ittara Owari no Isshuukan [hardcase8translates] [Full Color]

Matsuri, a demon girl used to doing the hunting, gets the tables turned on her in a week-long game where a single climax means it's all over. Bound hand and foot, teased with taped toys and a pressed, swelling bladder while the sigil glowing above her hips burns hotter, she spits threats through tears and drool even as her body betrays her. When penetration finally comes with strict orders not to pass out or break, the line between torment and bliss dissolves into a denial-drenched spiral she might not walk away from with her pride intact.
