Mrs Ks girls night out last night... Wasn't!!

Mrs K said a few days ago that she was going out on a girls night out Saturday night.. I never gave it a thought even though she had on a short skirt, a very low top with a push up bra. Just before she left she pulled her skirt up to her waist and showed me her smooth shaven pussy.. no knickers.. The whole night I couldn't stop thinking about her being out in town dressed so sexily and knickerless...Men were bound to be ogling her and ******* her on the dance floor maybe fingering her pussy..
This does turn me on of course...
However all was not as I'd thought... She came home around 4:30 in the morning, quite drunk and very disheveled.. She took her clothes off and just tried to slip into bed but I wanted some fun first.. It was then that I realised that her pussy was all red, puffy and swollen.. When I put my finger in her I could feel she was all sticky and her pussy was full of cum.. She'd been very recently fucked, even her tits were all red and blotchy from being groped and squeezed. Her nipples too tender for me to pinch..
After some quizzing she admitted that she'd gone out to meet a guy she'd been chatting with and exchanging sexy pics on-line for a few weeks.. She'd booked a hotel room after meeting in a club in town.. She said she couldn't wait to have his big cock in her pussy after seeing the pics he'd sent her.. She admitted that he didn't disappoint, fucking her hard three times in different positions, filling her pussy with his cum each time before they left and she got a taxi home.. Listening to her admission really turned me on so I gave her a really hard fucking from behind while spanking her ass as hard as I could, adding my cum to her well fucked pussy..
This guy is also married but they've already agreed to repeat the experience again sometime!
