Father, Mother… Tokyo's adult women are truly amazing in every way. Summer vacation… I came down from my hometown to visit my brother in Tokyo… Unfortunately, my brother was away on a business trip for four days… During this time, my live-in girlfriend took care of me… I unexpectedly started living with my brother's girlfriend! ? Was it because of her sexy clothes that I was being tempted? Was it the composure of an adult? Or was it because my brother and I are two people, so I was careless? Unconsciously, she was being overly bold in front of me. Ah… I'm embarrassed to my brother… but… my sister and I want to do some very erotic things… Hmm~ You can give me a little, just close your eyes… You absolutely can't open them… Overly excited and out of control, I thrust violently several times while sweating… Huh? I can't ejaculate inside!
