So the ex wife came over yesterday I thought to bitch me out about messing around with one of her friends. At first she seemed upset but then I got the distinct impression that she wasn't mad but jealous. She was coaxing me for more and more details and to be more and more graphic. She went so far as to have me point out exactly where the encounter had happened. She asked if she had crossed my mind while it was happening.

It was at that point she just blurted out "show me what you did to her!". I had to explain that it was more what she did to me at first. Her mouth dropped in shock and turned to walk out. I caught her by her hand and spun her around and gave her a big passionate kiss. At first she seemed to resist but quickly began reciprocating the kiss.
I wasted no time in undoing her blouse and removing her bra to see the beautiful breasts we had given her months before we broke things off. I slid my hand up her skirt and began to tease her through her panties. While she gently sighed "We shouldn't" I could see her knees beginning to buckle and could feel her pussy getting wet.
I spun her around and leaned her over the edge of the couch. This ironically the exact same spot where I had fucked her friend.

I let my pants and shorts fall to the floor and spit on my hand before giving a quick rub to my cock to slicken it.
I think she assumed I was going to go down on her because when she felt the tip of my bare cock she moaned "I'm engaged!" I just kept sliding in deeper. She just started moaning "oh fuck...oh fuck...over and over" and that's exactly what I did. After just a minute or two I could feel her pussy fluttering on my cock and I knew she was cumming. That made me go all the harder and I pulled her by her hair to make her back arch. Her beautiful breasts were bouncing wildly in the reflection of the living room windows. I started to cum hard and after several pulses she realized I was too. She turned to look back at me. It was a mixture of look; both wishing she had the willpower to pull away and at the same time a pleading look not to stop. I pulled back slowly, then walked forward to have her suck every last drop from me and taste her own pussy.

A wave of embarrassment or shame seemed to well up and she quickly put herself back together and left.
