[Pecan (Makunouchi)] Sparta no Mama

A ruthlessly affectionate, busty spartan mama takes complete ownership of her son's discipline, punishing his balls for ever smaller mistakes both at home and outdoors where humiliation leaves him clutching himself in public. From that day on she watches his every attempt to masturbate, stopping him with a calm smile, teasing that too much will turn him into a monkey and ordering him to accumulate his seed until she allows release. Twitching, spurting and denied at the edge of an aching cum, he remains helplessly under the control of the voluptuous woman who decides when — and if — he is permitted to finish.
