Rio, a beautiful, busty, and well-built college student, is my childhood friend and has always called me "big brother". Rio is always flirting with me, and she always bothers me. One day, when I was feeling down after being dumped by my girlfriend, she pushed me down and said, "Rio knows you better than me," and gave me a blowjob. I was confused, but her sexy lips and deep blowjob made me cum in her mouth. Because of that, Rio became obsessed with my big cock and boldly seduced me in a transparent bunny costume, saying, "I want you to cum inside me..." I was completely captivated by her erotic appearance, and I lost my reason and ended up having creampie sex as Rio had planned... Slutty cowgirl, lovey-dovey face-to-face cowgirl, deep titty fuck blowjob, continuous squirting creampie... a total of 7 ejaculations of libido-releasing sex. 110 minutes of being completely blown away by Riona Ryukawa's transparent bunny costume.
