On a business trip to Tokyo, I stayed at my older brother's place. It was the third time I'd been alone with my sister-in-law, Kanna, since their wedding. While eating a simple home-cooked lunch, my brother called to say he'd be home late. Right then, Kanna brought out some whiskey—laced with sleeping and erection drugs. Unaware, I drank it and quickly lost consciousness. When I woke up, my hands were bound, and Kanna was riding me in a cowgirl position, thrusting her body wildly. Feeling neglected in her sexless marriage, she began teasing my rock-hard cock, unable to stop herself, grinding her hips fiercely until she drained every drop of my creampie.
