Mom and Dad... Tokyo adults are really something else. During summer vacation, I came to my dream city, Tokyo, to visit my brother... Unfortunately, he's out of town for four days on a business trip... In the meantime, his girlfriend, who lives with us, will be taking care of me... Starting an unexpected cohabitation life with my brother's girlfriend!? Is she seducing me in her sexy clothes? Is it her adult confidence? Or did she let her guard down because I look just like my brother? She's making bold, unconscious temptations right in front of me. Ah... I want to do something really intimate with my sister-in-law, even though it's wrong... It's okay if you let me cum, but please keep your eyes closed... You absolutely can't open them... I got so excited that I went wild, sweating profusely as I pounded her repeatedly... What!? I can't cum inside her!!!
