Waited for so long

We had known each other for years. We had both been married and divorced and supportive of each other through our crisises but never hooked although obvious connection as we worked together and she is 10 years younger. She fell pregnant and remarried but over time we became close due to working together and i suspected she shouldn't have married him and was sorry she did.
On one of our many after work chats we joked around I asked why we hadn't hooked up - she said we should have and I agreed. During our next chat I bravely told her that I had often thought of us having sex (code for wanked!) and always imgined her in black underwear as she wears lots of black. She giggled and told me she does wear black underwear and did I want a peek at her bra and black thong panties? I tried to stay calm and replied that I would.
She checked that no one else was around, bent over the desk and asked if I'd like to lift her dress up. I slowly did and raised her black dress over her bottom and on to her back. Her alabaster bottom smiled at me in her thong panties. I immediately bent down and kissed her buttocks - she didnt protest - I ran my hands over her bum and kissed her. I pulled the string to the side and french kissed her rosebud before thrusting my tongue deep into her arse. She moaned and said she'd never done that before ... but don't stop!
I rolled her over on the desk and slowly pulled her panties down and took them off. I wrapped them around my wrist and sucked and licked her deliciously smooth shaved pussy. She pushed my head deeper and made me eat her pussy until I tasted the familiar taste of her cumming in my mouth.
I left her to euphoria for a while while I shut the doors and stripped naked. She sat up on the desk, smiled and said in a husky sexy way .. stroke your lovely hard cock for me. I slowly wanked as she get off the desk, knelt in front of me and took over the stroking with both hands before expertly sucking my cock. As my cock swelled to cum she stopped, stood up, removed her dress and then her bra and fed her pert B cup tits to me. I sucked like a man who has waited 8 years to suck her tits(!!)
She then moved away, bent over the desk and demanded that I fuck her hard and fast and unload in her very wet pussy. I obliged and knowing how she enjoyed the arse sucking and tonguing, inserted my index finger in her arse as I fucked her. She moaned "Oh yes please .." so I continued until we both came together.
I withdrew my cock and was about to get dressed when she told me stop and proceeded to suck my cock clean and squeeze my balls. She sucked and stroked until my cock got hard again and then proceeded to take photos of my cock with her phone - she wanted them to share with her friends although she said she wouldn't tell them whose cock - I don';t care - it could be a good ad for me!!!
