SCPX-428 - ウチの息子性欲モンスターで困ってます…

It's a somewhat cliché story where a mother asks an acquaintance to persuade her shut-in son who only watches adult videos, but the acquaintance ends up taking his virginity for reasons that are hard to grasp, and his unexpected stamina makes him cum repeatedly. What bothered me was that the buildup to the sex scenes was almost identical in all three parts, and the mosaic was so huge that her face was completely hidden during fellatio. However, the variety in the scenarios—1) being used repeatedly while covered in semen hours later, 2) a 3P involving the mother, and 3) being continuously used until the fade-out while still penetrated—was a nice touch.
