Enveloped in the steam after his shower, he became fully aroused upon seeing his mother's unguarded towel-covered figure—attracted by her alluring nakedness. (Tsubaki Sae, VENX-386)

It was dusk, as usual, in the living room. The mother, having just showered, appeared wearing only a towel. The scent of shampoo wafted from her slightly damp hair. Unsuspecting, the mother paid no heed to her son's gaze, bending down to search for her underwear. Her white buttocks peeked out from under the towel. Reason crumbled instantly before the tantalizing glimpse of her private parts. Her son, embracing her from behind and caressing her body, made her cry out in surprise, but it was too late to turn back.
