[Arimura Daikon] Cuckoldry Mediator Gyaru [Coffedrug]

A trusting boyfriend sends his girlfriend off with a cheerful gyaru kouhai and her towering, scarred companion, telling himself a condom rule and one night of swinging will keep things safe. Curled together in sweat-soaked sheets, the shy girlfriend discovers a cock that reaches places her senpai never could, while the grinning gyaru films every squelching thrust and teases that her man might just ruin him for her forever. When the video arrives later, he'll finally see how willingly her hips learned to match another man's rhythm—and how little she wanted it to stop.
