I wanted to try mfm so much but no chance with my wife and the ads I'd responded to hadn't led to anything. One day whilst reading the massage services section in the Birmingham mail I saw an ad saying Solihull couple £80 all inclusive. Nervously I phoned the number and spoke to a man named Chris who sounded like a decent bloke so I made an appointment for that afternoon. My heart was pounding when I rang their doorbell later but Chris turned out to be so friendly I soon felt at ease. He shook hands and invited me into the kitchen to wait as Sandra was showering. She wanted to be squeaky clean for me. Chris chatted saying this was just a part time thing for them to pay for weekends away and they both enjoyed it anyway. After a while he left me to check if Sandra was ready and then came halfway down the open staircase to invite me to the marital bed. He showed me which door and said I'll leave you to get acquainted and come back in a few minutes. I walked nervously in. Sandra lay seductively on the bed with a welcoming smile. Like Chris and I she was mid 40s, blonde, I'd say size14 with ample tits and sexy long legs. She would have been a stunner in her prime and was still attractive. She wore a red camisole top with matching suspenders and red fishnet stockings. We exchanged names and shook hands and Sandra invited me to undress. I quickly discarded clothes and got next to her on the bed where she immediately began kissing me. The kisses were very passionate and I couldn't help groping her shapely arse until I felt a cock press against it as a now naked Chris had joined us and nestled into Sandra's back, kissing her neck as she and I played tonsil tennis. Turning onto her back still wearing that horny smile Sandra said lets see what you boys have got. Chris knelt so that his cock was just above her face so I did the same on her other side. She took a cock in each hand and gently stroked mmm she said, I'm gonna be spoiled. I'm quite well endowed but Chris was slightly bigger. She sucked us in turn never letting go of either cock. She even managed to get us both in together for a short time. As she withdrew us she said huskily to Chris get me wet for him. Chris hurriedly buried his face between her thighs and smiling at me she said, very wet cuz he's not small. She grabbed my hips and pulled me to straddle her. Fuck my face Steve she said hungrily and opened her inviting mouth. I've had amazing blow jobs over the years but never fucked someone's mouth before. She just took me balls deep as I thrust in and out. After a few minutes Chris tapped me gently on the back. I think she's ready he said passing me a condom. Sandra lay panting after her double onslaught of pussy licking and face fucking, her face was shiny with precum. As I put on the condom Chris slipped his dressing gown on saying I'll be back in a bit, enjoy her. Sandra had regained some composure and laughed I'll enjoy him and she opened her legs as I slid down her body. I entered her easily, she wasn't the tightest but being in someone's wife felt so horny. She really got into it wrapping her legs around me whispering obscenities. She started bucking underneath me and knowing I was making her cum excited me to orgasm and I pumped my seed into the condom. I stayed inside her enjoying the afterglow until I realised Chris was standing in the doorway smiling. Was that good mate? As I withdrew he saw the amount of cum I'd deposited in the condom and said fucking hell it was good. We all laughed. Listen Steve, said Chris, you've still got plenty of time left but our next appointment has turned up early. Do you mind if he joins us? Honestly say if you do and he'll have to wait. Well I needed recovery time and it would be another new experience but it was the sluttish glint in Sandra's eyes at the prospect of 3 hard ons to play with that made me say yes I don't mind. I'll reveal all in part 2 if people are interested.
