[Etori] The Autumn Sea Is Full of Dangers

A father takes on a beachside "men's swimsuit challenge" that leaves him bare-chested in drawstring trunks—until two predatory beachgoers corner him behind the rocks. While his young child waits for Naoto to come back and play, the pair force him into relentless double anal and feminization, teasing that a female look suits him better and that he'll really become a woman if he keeps enjoying it. Spent and humiliated by taunts of being a terrible father, he can only blush as the two promise plenty more "fun" to come.
