Yesterday I finished work early and got home at 4pm so I texted my wife Sarah to tell her I was home and do you fancy a bit of time together before we pick the kids up from their grandparents. 9 times out of 10 it would be a no but the text a got back said yes I will be there in 10 xx. Just after 4:30 somebody knocked on the door and it was my mate mark who wanted to borrow a tie for an interview he had tomorrow. Two minutes later the door went and it was Sarah who shouted to please come and fuck me! unaware mark had just turned up before her. As she walked in to the living room Mark was laughing as she went bright red. Mark told Her don’t be embarrassed I wish Amy was like she’s never in the mood. This calmed her down as she asked “oh really, what do you get up to then”. She had now got interested in his life whilst I was trying to get him out the door. They walked into the kitchen talking as I followed and said I will need to pick the kids up in an hour and winked at her, which in turn she gave me a smile. As I walked over to her I grabbed her arse and started stroking her waste and with every motion I got further and further up to her tits. Mark was facing Sarah watching my hands getting closer and closer to her tits , he stopped talking to her and just watched. As my hands finally cupped her tits I stood behind her kissing her neck, she reached round and rubbed my cock through my jeans. Probably her only fantasy was to be watched by someone as we fucked so I thought this may be a good time to do it, but she pulled away from me and said I think we should go upstairs, this is when I thought she would want Mark to go but she looked at him and said you can come up to if you want and see what your missing. As we got in to the bedroom Mark went and sat on the chair in the corner of our room while me and Sarah got on the bed. We were kissing and undressing each other. I was fingering her whilst sucking her nipples then she sat up and started to suck my cock, as I glanced over to the corner Mark had his trousers around his ankles and was wanking his cock, it was massive it had to be at least 10 inches long, Sarah stopped to see what I was looking at and as soon as she saw his cock she took my cock out of her mouth and said to him to join us on the bed. She then bent her arse towards him and carried on sucking my cock, Mark got up from the chair took the rest of his clothes off walked over to her, grabbed her waste and shoved his cock straight in her. Over the next 30 minutes we took turns in fucking her, then I asked if I could fuck her arse. So as she was riding Mark I got behind her and eventually forced my cock up her arse and over the next couple of minutes we fucked her at the same time with all three of us moaning. Sarah then came first, which then made me cum up her arse so I got off and watched mark fuck her until her came in her pussy. Sarah got off the bed with cum running down her legs and went to the bathroom, Mark got dressed and left and I went to collect the kids. Hopefully we can do this more often if she’s in the mood
