(27m) My little sis took it too far

My sis (20f) and I are very close. She is a fiery, wild party girl of a person; whereas I am very chill.

I always knew she could be a bit of an exhibitionist; she had no problem changing in front of me, and I’ve seen her topless several times in my life.

But one time we were in a hotel room to together when traveling for a friends wedding. After the reception, she was very drunk (me too, but less so).

We got back to the room and she starts to change in front of the bed. This was nbd for a minute; but I had never seen her butt or pussy before. She stripped COMPLETELY NAKED. While just casually talking to me.

Then as she is still naked, I turn on some music thinking it will distract her. Nope. She literally bend over the desk in the room and starts twerking her ass.

I’m staring at her butt as her (I will admit) fat ass cheeks are flopping around like water. I can see her bare pussy lips shake too.

She tried to get me out of bed to dance with her….but I was embarrassed about the boner I had 🙈🫠
