[MF] I came inside my Wifes Sister

If you want backstory my previous post outline the situation. Yes i know what im doing is wrong but i feel like its too late now.

I’m going to try to keep it short.

My wife was out for the night. She went to her parents then it started to storm so she texted to say she’s gonna stay the night.

I read the text, replied then went back to focusing on my sister-in-law sucking my dick. She had just got home from class 30 mins ago and after she showered we wasted no time. She is so good at sucking deep. Its the best head i ever received from a woman.

I tell her the situation and this is the first time we get the night alone together since we started “this”.

She told me thats good news and that she didnt wanna waste the night so she takes off her underwear and straddles me. She teases my dick for a little then just puts it in and starts riding me with passion.
