Ex-Wife's Surprise

Met an old friend last night. She was my ex-wife for five years. Drank a few beers, talked about the past. We ended up back at her place. Her new boyfriend left town, she said. I entered her bed after some heated kissing, my dick hard as fuck. She took me in her mouth, bobbing fast. Then we fucked until dawn. Anybody else ever get it on with their ex?
