Fair-skinned Eri Saeki plays a shameless mother who flashes her pussy and seduces her adult son's virgin friend. She asks him to rub insect-bite cream around her cleavage and pussy, shows him a woman up close, lets him lick her, then rewards him with a blowjob. She guides him through his first penetration and drains his cum with her mouth after warning him not to finish inside. Their forbidden affair continues, and once her eager pupil becomes skilled at sex, he makes her climax and gives her a thick creampie.
