[SINK] Smiling Mother (Bisyou no Inbo)

Takashi's devoted mother is a voluptuous milf with soft big breasts and a delicate beauty mark who scolds his failing 56-point exam only because she cares desperately about his future, kneeling to hold his hands and promise her strictness is for his own good. That selfless devotion makes her the perfect target when a pair of smirking classmates in schoolboy uniforms corner her in scanty lingerie, praising her sexy, hairy body and warning they will show her son what she has become if she disobeys. Torn between remaining the smiling mother who urges her son to be honest like his father and surrendering to a coercive mmf threesome that leaves her flushed in ahegao and filled with nakadashi, she discovers a helpless, cheating pleasure in the punishment she insists she does not want.
