Her Big-breasted Younger Sister, Who Is Innocent And Would Definitely Let Her Have H, Missed The Last Train And Came To Stay. Yuu Tano

A sudden call on Saturday night, and a late one at that. 'I missed the last train, let me crash at your place~' It was from my girlfriend's little sister, 'Ui.' I tried to refuse, but a few minutes later, the doorbell rang. And she just let herself in. She seemed to have been drinking, and was even closer than usual, with lots of physical contact. Plus, her top was loose... She pressed her chest against me like she was deliberately tempting me. What if my girlfriend finds out... 'Hey, you're touching me.' 'Hmm? I'm pressing it on purpose.' Oh, I might be in trouble.
