GVH-628 My girlfriend's sister Ayaka, a technical instructor for ejaculation courses, makes me a male model and plays with my blindfolded dick until I fail to cum many times.

Ayaka Tomoda, secretly a technical instructor for AV actresses and sex workers, asks her sister's boyfriend to fill in as a male model when the original doesn't show. Covered by a sheet with only his dick exposed, he is subjected to Ayaka's amazing techniques and cums repeatedly, then the students continue playing with him until he faints in agony. The 174-minute release features an orgy and oral sex.
