[Rena's first dick experience] The perverted father-in-law has been observing the growth of his wife's stepchild's breasts for 10 years and loves immature nipples. Before he had an adult body, he played tricks on me and made me develop a predisposition to ejaculate prematurely. At first she hates it and resists it, but she drowns in the unpleasant pleasure that she cannot resist. Then, when I wipe her nipples at high speed, she cums in agony and has an ahegao face! The man with abnormal sexual desire cannot stop being excited by the sight and the mischief escalates. Gradually, she gets addicted to the exciting SEX where she plays with her nipples and is pistoned with a cock.
