Fucking My Ex Wife and Best Friend

My girlfriend's best friend has started coming on to me. I resisted her temptations until last weekend.

She has been going to the same gym as me and has a lovely body and very generous 34DD assets. I have often fantasised about shafting her and finally got my chance.
After a sweaty session at the gym I made a joke about her melons. She gave me a sly wink and whispered, "How about getting a better view?".

I followed her to the ladies' changing room, my love length throbbing. She whipped off my shorts to reveal my erect cock and began to wank me off. Eager not to spaff too quickly, I pulled away and led her to the showers. I lasted about 10 minutes before exploding all over her arse. I now have regular shower sessions with her. My girlfriend is unaware what's going on.

I've also recently been picking up my ex-wife in my car on the way home from work. She is always at the same bus stop and we still get along well.

She married the fella she left me for, but she has feelings for me. She told me she regretted dumping me and the other day started to squeeze my cock as I drove her home.
She unzipped my pants and pulled out my eight-incher and started sucking on it. The following day I picked her up and pulled in to a layby.

I got my cock up her and fucked her like the good old days. Now we're at it every day, and she says she will leave her hubby for me. Great really because she is a bit of milf and I would love to have other opportunities to fuck her in public. If we were together we could go dogging and all sorts.
