[Akireru Shoujo (Akire)] Boku ga Saki ni Suki datta Gibo ga Yarichin no Charao-tachi ni Tanetsuke Sareru Natsu

Yuna, a newlywed stepmother with a body that stops traffic, thought a summer beach trip with her stepson would be innocent fun—until a pack of sun-bronzed gyaru-oh corner her on the sand, peeling her bikini strings loose and cooing that a married pussy this good deserves to be taken raw. Her protests of "no, stop" melt into trembling moans as they pound her deeper than her husband Shigeru ever could, sweat-slicked and gasping apologies to the boy watching from just out of reach. A sweaty, sun-soaked netorare descent where the woman he loved first is claimed by the very charao who never lose.
