[Fuuga] Boshi Soukan ~Kaa-san wa Saikou no Onapet~ [Full Color] [DarklordMTLs]

After his mother walks in on him masturbating, a teenage boy finds the household power balance quietly flipped—and pushes his luck until flustered Reiko is squeezed into a schoolgirl uniform, cheeks blazing as he orders her to touch herself right in front of him. Her protests collapse fast once her son's hands are on her, the curvy housewife's huge breasts swallowed around him as she services him by hand and mouth, scandalized that her own boy is calling her by her first name and comparing her to a perverted AV actress. The closing narration admits his fantasies have grown all the way into reality, and with a teasing 'to be continued,' mother and son are left teetering on the edge of something even hungrier.
