Futei no karada - the Unfaithful body [MTL] {sandlot}

A voluptuous, bespectacled office worker in a fitted business suit is drawn into a compromising three-way affair with two men, her large breasts, rounded belly, and full hips emphasized against awkward negotiations and increasingly explicit group sex. The encounters shift between a cramped living room, a rough wooden room, and a stark apartment as the men debate pregnancy, condoms, and whether to withdraw while she remains frustratingly composed. Linked chapters—including “Impregnation Game” and “Pregnancy Game”—frame infidelity as a recurring, transactional obsession fueled by oral sex, anal intercourse, double penetration, and riskier claims on her body.
