[Aoi Hitori] My Son's Problem (COMIC Magnum Vol. 139) [Amoskandy]

When a devoted mother decides her shy son Takuma needs hands-on practice before pleasing his girlfriend, a flustered bathroom inspection of his big penis melts into her practiced mouth and a sweat-drenched session where her huge breasts heave through trembling climax after climax. She strokes him, sucks him, rides his tongue, then coaxes him inside her aching pussy and begs him to move slowly as she coaches her virgin through every thrust. The sweetest twist comes afterward, when a photo of the smiling girlfriend appears and mom purrs that finishing inside is something he can only ever do with his mother.
