[SONE-398 English Subbed] – My girlfriend’s innocent sister, who I’m sure will have sex with, missed the last train and came to stay with me.

SONE-398 English Sub – The boyfriend gets a surprise call from his girlfriend’s sister, Hana, asking if she can come over. At first, he’s a bit unsure, but he eventually lets her in. When she arrives, he’s taken aback to see her tipsy and dressed in a way that’s pretty revealing. Hana starts flirting and acting suggestively, clearly hinting that she’s interested in something more than just a friendly visit, even though it could lead to trouble with her sister.
