The Hirayama and Ootsuki families are enjoying a joint summer vacation by the sea. By chance, the two mothers separate from their families, and a pair of lecherous eyes fixate on them… This is Yarimoku Beach, a holy ground for hookup-minded men looking for one-night stands. These men, driven solely by their basest instincts, swarm the beach in search of easy targets. The two mothers, swayed by the smooth talk of young, tanned men much younger than their own sons, are quickly led astray. Their voluptuous, mature bodies soon betray their hidden desires, and they forget about their husbands, their sons, and everything else as they dive headfirst into a summer of fleeting, carnal pleasure… A non-stop ADV about milfs being picked up and taken!
