My wife's sister was staying with us over the holidays. She's recently divorced and made it no secret that she's sleeping around and enjoying being single again. She's thicker than my wife with a bigger ass and breast. She's also knows we've been experimenting with hot wifing and I've watched my wife get fucked by another man twice now.

One night I needed some wrapping paper from the guest room she was staying in. I knocked on the door, didn't get an answer, so I went on in. I could hear her inside the room and knew she'd just gotten out of the shower. As I walk in I see movement towards the bathroom.

She's bent over with her bare ass facing me drying her hair, doing that thing women do when they are tying their hair up in a towel. I froze. Her big, smooth naked ass in full view. I didn't think she saw me and I planned on taking it all in.

While still bent over she says "What's up?". Like it wasn't a big deal that her fat naked ass was facing me. I told her that I was looking for the wrapping paper and I was sorry. She stood up and shrugged, indicating she didn't care. She turned to face me and put both hands on her hips. Ozzing sex appeal.

She was so confident and sexy. Something I'm not used to at all with her sister. Full naked, and one eye brow raised she didn't seem to mind that I just stared at her. It took a minute for me to snap out of it. I walked over by the bed and grabbed the wrapping paper, but my eyes never left her naked body.

From what I could tell she was enjoying it as much as me. I walked out the room in silence. She still had one eye brow raised and a sexy smirk on her face.
