SONE-832 | My girlfriend's big-breasted sister, who clearly wanted to have sex with me, missed the last train and came to stay the night. Kohinata Miyu

A sudden phone call in the middle of the night. <br>"I missed the last train, can I come over now?" <br>Although I knew it was a bit strange to accept my girlfriend's younger sister, Miyu's, request, <br>I reluctantly let her stay. <br><br>She came to my house, took a bath, and relaxed on the sofa. <br>My eyes were drawn to her voluptuous cleavage peeking out from under her loungewear, <br>"Are you looking at my breasts? Are you... getting turned on?" <br>What, was she showing them on purpose? She didn't seem to be inviting me, <br>but it was clear that she was open to having sex. <br>She then mischievously brought her soft-looking lips closer to me as if inviting me to a kiss, and my reason collapsed!! <br>"I won't tell your sister?" <br>Today I'm going to make a mess of my girlfriend's cunning, devilish, and fun-loving sister!!
