A new series that is particular about stopping and patience. The stage is the "Ejaculation Management Institute", which thoroughly researches how to manage male ejaculation. Shiho Egami is the director. A middle-aged man whose erection is freely managed by a low frequency current, and an M man who is stimulated by assjob and intercrural sex until just before Iku and is stopped to the limit many times and finally goes mad. The highlight is to stop the cowgirl position with a big butt as a weapon. It forces a man who is about to come out immediately to endure desperately. It's full of real blame that makes you feel like you're watching.
