Takeshi and Daisuke, lifelong friends, faced fading sex lives and stalled marriages. To fix this, Daisuke suggested they swap wives. During a gathering, Takeshi told Sakura about Daisuke’s idea. Hesitant but persuaded, she agreed. Takeshi and Yuna went first, with Sakura and Daisuke watching. Sakura saw her naked husband fuck another woman right before her own husband, no condom, cumming straight into Yuna’s womb! Daisuke even whipped out his cock and jerked off in front of her. Seeing another man’s dick made Sakura so horny her panties were soaked. After they showered, she and Daisuke fucked in the couple’s bedroom. From then, Sakura shed her shyness. All four roamed naked at home, played cards and 'guess the cock' games, fucking whenever they wanted. Their marriages grew stronger...
