My girlfriend's big-breasted sister, who obviously wanted to have sex with me, missed the last train and came to stay the night.

A sudden phone call rang in the middle of the night. ``I missed the last train, so is it okay if I go now?'' Although I thought it was a bad idea to ask my girlfriend's younger sister, Miyu, I reluctantly decided to stay the night. She comes to my house, takes a bath, and relaxes on the sofa. I couldn't help but notice the voluptuous cleavage peeking out of my loungewear, and I said, ``Are you looking at my boobs? Maybe... you're getting excited?'' Huh, were you showing them on purpose? It doesn't seem like he's inviting her, but it's clearly an atmosphere where it's okay to have sex with him. Even more, my rationality collapsed as I naughtily brought my soft-looking lips closer to him and invited him to kiss me! ! ``Why don't you tell your sister?'' Today, I'm going to mess up my girlfriend's little sister, who is cunning, devilish, and has a good mood! !
