seduced by a hot, curvy girl (m/f) (cheating)

My wife and I went out to celebrate her sister’s birthday a few nights ago. We went to a nice restaurant and then bar hopped at nearby bars. Her sister has a lot of friends who are pretty cool. About 20 people dwindled down to 6-7 and my wife had to get up early and wanted to go. I was talking to another guy named Rob and a girl named Lindsey about music festivals and stuff and didn’t want to leave. My wife took an uber home and I stayed and had a few more drinks. Soon my wife’s sister left, and the party was about over and people were settling up at the bar.

Lindsey came up to me and asked if I wanted to share an uber with her. We lived pretty close so I said sure. I had been to Lindsey’s house once before for a party and I noticed that she lost quite a bit of weight. She used to be on the BBW side and now she was really thick and curvy. She didn’t do much for me before but I was admiring how sexy she looked in a tight top and a black skirt.
