I'm living in my brother's house while I'm a ronin... Every day I spend with my kind brother and cute sister-in-law Riko has changed since that rainy day. From the first time I couldn't resist the temptation of my sister-in-law's wet transparent body and was made to have cum-squirting vaginal sex, my sister-in-law seduced me like a little devil in the bathroom, right away. next to my brother. . "I've been waiting for you for so long...! Come inside... Let me inside...!"
