Riho Fujimori's sensual charm completely shatters my self-control. She suddenly shows up at my new home, recently married to my wife, and carelessly exposes her voluptuous thighs and cleavage. During a drinking session, the atmosphere between my sister-in-law and me naturally heats up. With our flushed bodies pressed together, she whispers in my ear, "Hey, let's do it?"—and I lose all restraint. Right next to my sleeping wife, I passionately thrust into her like a wild animal, fucking her bareback in the cowgirl position. When my drunken wife wakes up and starts searching for me, we hide in the closet, desperately muffling our moans as I keep pounding her tight, wet pussy, unloading an endless stream of creampie after creampie. This twisted tale of forbidden lust, filled with guilt and thrill, captures every depraved moment.
