In the summer, the maximum temperature in my hometown approaches 40 degrees... My brother who lives in Tokyo keeps coming back to visit even after getting married. I always thought my sister-in-law Yuu was beautiful whenever I met her... But then she suddenly started showing me her panties under the table while we were eating! I couldn't resist her temptation with her steamy panties and her body shining with obscene sweat, and we had a scorching hot sex session with Yuu, whose body was so erotic that I had always admired her, and our bodily Yuu were sticky and intertwined! Her body was so hot that it was hard to get enough of it, no matter how many times I came inside her...
