Seduce your sister's lover

Maron Natsuki is an older sister who has just lost her love. Knowing that her sister brought her boyfriend home to stay for two days while her parents were on a business trip, she planned to seduce her sister's boyfriend to get his cock. The guy really wanted to have sex, but Maron Natsuki's sister forced him to wear a condom, but Maron Natsuki didn't need a condom or load at all. She even allowed him to cum inside (creampie) so he became more and more infatuated with Maron Natsuki's girlfriend's older sister even though he felt sorry for his girlfriend.
