[MF] My slut of a girlfriend likes to send me my sister’s nudes

Growing up relatively close in age, my sister and I have always been attached at the hip. As one of us made friends, the other one would, and a few times we’ve had relationships pop up amongst the friend group.

For about 3 months now, I’ve been in a relationship with one of our mutual friends, being my sister’s closest friend. We practically grew up together, but that never stopped us from flirting or finding one another attractive, so I finally ended up making the move.

One thing I wasn’t anticipating, however, is how much of a freak this girl is. She taught me so many things about sex, and opened my mind to some crazy kinks. But, the craziest thing of all happened when we were sexting one night while she was on vacation, and she asked me a question that I’ll never forget.

“Be 100% honest withe me. Do you think [my sister’s name] is hot?”

I was flustered at first, but eventually answered yes. My sister was attractive. Relatively tall, slim, tan, and athletic with dirty blonde hair and big blue eyes. After she got the confirmation she was looking for out of me, she asked me an equally shocking question.
