English Otonari no Kokujin Otto ni Dakarete Nakimodaeru Saiai no Tsuma Sono Hikikae ni Ajiwau Kokujin Tsuma no Hada -Rebirth | お隣の黒人夫に抱かれて啼き悶える最愛の妻。その引き換えに味わう黒人妻の肌。 ～Rebirth～

Want to have sex with each other's wives.

It started with a casual remark at a drinking party. A joke between husbands that they couldn't tell their beloved wives... yes, it should have been a bad joke. But they were both too sober to dismiss it as a joke. Yet an uncontrollable heat had spread throughout their bodies. They had imagined that impious and immoral fantasy to be incredibly rich and sweet, with too much clarity.

--Are you serious? --I'm serious.

They wanted to make the nights when they felt unsatisfied more fulfilling. The husbands knew that jealousy would be the ultimate spice, and guilt would be the primer for pleasure. And surely their wives, in their bodies, in their instincts, must know it too.

A one-time mistake, a one-night spouse swap. While feeling a definite premonition that the excuse of "just once, only once" would soon become unusable. The black husband embraced the Japanese wife, the Japanese husband embraced the black wife—they powerfully embraced the beloved spouses of the neighboring couple they shouldn't have.

--That was the beginning of a secret spouse swap that continued, hidden from each other's beloved wives.
