Mother-son rape, Mamiya Yui, GVH-874

Recently, for some unknown reason, Wei's nipples became swollen, and their sensitivity increased as well. Although the hospital diagnosis showed nothing abnormal, just to be on the safe side, she decided to tell her son and show him her enlarged nipples. "Don't keep staring, it's embarrassing..." When those swollen and full nipples were displayed before his eyes, a lewd thought instantly welled up in the son's mind. "Mom's nipples are so sexy..." So, to help the troubled Wei, the son offered to massage her nipples. But as expected, the stimulation of her nipples alone brought Wei to a complete orgasm! Seeing Wei's wanton appearance in ecstasy before him, the son's excitement was completely uncontrollable, and the two thus opened the forbidden door to mother-son incest.
