鉄壁虎穴ノックアウト

A Japanese Brazilian top X shy Japanese bottom Leo and Kuro grew up together. After deciding to follow the same path as adults, they ended up becoming M.M.A. rivals in the ring. Kuro, who just can't get a win against Leo inside or outside the ring, has to do whatever Leo asks as punishment... which usually leads to the bedroom. Nevertheless, Kuro is still too stubborn to accept Leo's love. His body, however, has no problem taking it! It's Mikumo's latest hot and steamy story: a battle between two M.M.A. fighters that always leads to one being K.O.ed in bed! (Source: Renta!)
