PPPD-905 I was seduced by your girlfriend's sister Ranka and the outcome.

I was seduced by Ranka, my girlfriend's older sister, and the outcome is that Yuki is having a good time with his girlfriend, but every time they make love, his girlfriend doesn't allow him to go bare and insists on using a condom. Then one day, he met his girlfriend's sister named Ranka, and a miracle happened. A wild girl, who couldn't care less about condoms or that he is her sister's boyfriend, took the initiative and the two secretly hooked up during the days he was there. What will happen next?
