Social networking has been blamed for plenty of marriage break ups, but it's also been the source of plenty of sex! My story is about something I've found out today and I'm still hard thinking about it! My wife, Sarah went out on Saturday night to an Abba tribute concert, not my scene and she was going with a group of her friends. It was fancy dress, her 43 year old figure looked amazing, tight shiny top, her nipples are always erect but looked so hot poking through, white hot pants, tights showing off her shapely legs, topped off with knee high white boots, her hair styled like something from Charlies Angels! When she arrived home she was pretty pissed, she passed out before I'd even had chance to fuck her so I was a bit disappointed to say the least but after looking at some pics on Facebook today it looks like only 1 of us went without sex! I saw some pics of 'Abba Nite' posted by a friend of one of my friends on Facebook, but as she'd been tagged I was able to see the pics, curiosity getting the better of me I had a crafty look! Sure enough, I spotted Sarah in the background in a few, looking more and more pissed but having fun dancing with a group of guys. I thought nothing of it until, obviously towards the end of the night, some slow records must've come on, and there was Sarah dancing with a bloke! They were blatantly chewing each others faces off, my cock sprang to life! I didn't feel betrayal, just immensely excited! We've never swapped, I'd love to but she's not into it. I'd love to watch her fucked by a man with a big cock, my 6 inches put to shame but a big hard thick piece of meat! Looking at the pics she might've had just that! The guy she was dancing with was tagged, I was able to check his profile, he's 31, single, lives locally, tall, muscular and hands like shovels! My heart raced when I saw more pics and then some comments! 'Steve fucked that MILF in the car park', 'she couldn't get enough of him' and various other comments, some which have now been removed but I've got them! She kept her boots on apparently! I'm tempted to e mail him and ask him what happened, or ask Sarah. Or should I leave it and hope they meet? I want to watch him fuck her but Im also bursting to know what happened! I hope he came inside her, it'd drive me wild! She's now friends with him and 2 of his friends on FB now so I'm guessing and hoping it won't be their last meet! Just need to plan my next move......!
