When I called a delivery health service, my wife's younger sister came! ! I tried it out, "Only once..." and it was a perfect match for sex and ended up having sex all the time at home.

I've been having a lot of trouble with my wife lately, and it's been a while since I last did not get into it. So I secretly called a delivery health service... Then came my step-sister Natsu! When I tried to change, thinking that this was bad, I told her, "Please keep it a secret from your sister," and she said, until the actual show...! However, Natsu-chan was so excited by the sex that she was so compatible that she greedily sought after her wife's eyes! If that's the case, I'll just have to just eat the poison and even have a secret bite!
