Even though he's already old enough, Ayumu's son still can't stop sucking on his mother Nana's gigantic I-cup breasts. When he throws a tantrum after missing school, she gives him a gentle handjob for his morning erection, and if that doesn't work, she makes him feel better with some sex. Even when he can't hold himself back before dinner, she prioritizes her son and jerks him off with her mouth. She gives her son a titjob to help him sleep soundly after he's having nightmares. With all this dedication, will he ever be able to stop sucking on her breasts?!
