Even before the age of fifty, the youthful and beautiful mother-in-law entered the son's futon in underwear to warm his son who complained of coldness with his own body. The mother-in-law, who had a strong sexual desire for her son who erected in response to such a bold act of her mother-in-law, shines her eyes. The mother-in-law who gets excited by stroking the erection Chi-ko greedily devours it and leads to ejaculation. The mother-in-law who straddles her son's face and licks the ripe mako without being able to suppress her lustful lust, seeks even stronger pleasure and extorts Ji-ko.
