We moved house last year to a fairly new development near the Eseex / Suffolk borders, my kids started at their new school and my wife started a new job full time, I stayed with my old firm prefering to travel that little extra distance because of thepay and hours. Becuase I work a 4 on/4 off system, I'm often home during the week so I get to do the school run. The first few weeks was the same, dropping the kids off, picking them up and not really talking to any of the other parents as I didnt know them. Just before last Christmas I was standing in the playground waiting for my kids to come out, when one of the mums, Gemma, came up and started to chat - apparently our daughters are best friends! Over some weeks she introduced me to some of the other mums and we'd chat if I saw them out shopping. My wife always made a joke about it 'be careful about those mums alone in the house all day!' One day in March this year,Gemma asked if I was any good with plumbing - other than the obvious jokes about inspecting pipes made by a couple of other mums! - I said yes. She explained that she had a problem with the pressure to her downstairs toilet, so I said I'd have a look at it tomorrow after I drop my kids at school, before she calls anyone professional. Now Gemma is early 30's, about 5 foot 6, medium build, but has all the right curves, she is attractive and has the deepest blue eyes I've ever seen. Her tits at larger than they should be with her figure - but as I'm a tit man, I dont care. Her husband is a bit of a prat,always putting her down in front of people. Next day I dropped the kids at school and walked home with her, she lives in the next road from me (I can see her house from my window - and can look stright into her back room). I grabbed my tools from the garage and headed back to her house. She answered the door wearing a fairly tight fitting t-shirt and cropped trousers, she showed me to the downstairs toilet and I set about finding the problem. After a while I found it (a stuck valve) and freed it. Job done. We chatted and she asked me to stay for lunch, so I did. We chatted about the kids, what we did for work (her a housewife) and the normal pleasantries. She then said 'could you imagine what the other mums would say if they knew you were here?' I laughed and said 'why, what do you think they would say?' All she said was 'well, you know - it'd be like that program 'desperate housewives'!' 'Only if thats what you want them to think!' I said with a grin, then added 'I know what you housewives are like, stuck in the house all day, preying on unsuspecting workmen.....' All she did was blush! But I could see that her nipples were starting to go hard under her t-shirt. I thought I'd take this further and see where she goes. I then said 'so I've hit the nail on the head by that reaction. Its probably something you've thought of but never had the nerve to try' 'What do you mean?' Gemma asked 'I mean - trying it on with some poor workman' I could see her going redder and, yes, her nipples were definitely harder, it looked like they could cut the material! I said 'Can I ask you a very personal question' She tried looked away and said 'maybe' 'Do you ever get bored being at home all day?' She nodded, 'And do you imagine doing things to break the boredom?' She nodded - but I could see her reply in her eyes. 'Do you ever think of having sex with someone who has come to fix something for you?' She turned away 'maybe' 'Then,' I said 'as you have a fantastic body, have plenty of time to spend before we pick the kids up.....' I thought to myself that I've got to keep going now 'do you want to break your boredom?' She turned her head slightly, but I could still see her nipples - hard as nails, all she said was 'how'. Fuck it, I thought - in for a penny. I walked over to her and put my arms around her waist, and whispered 'forgive me if I'm misreading you, but do you fancy coming upstairs and making love' She turned and smiled and said 'no'. My first thought was 'oh fuck, goine too far'. But then she said 'I only make love to Steve (her husband), but you can give me a good fucking' She lead the way upstairs into her bedroom. My cock was rock hard by the time we entered. She stopped by the bed, lifted her t-shirt over her shoulders, leant round undid her bra to reveal a lovely pair of 38E's, she then undid her cropped trousers and let them fall to the floor, then slip her knickers off and stepped out of them. SHe then slide into bed, covered herself and then pulled back the covers on the other side for me. I stripped naked and slipped into bed beside her. She kissed me roughly and said 'I want you to fuck me hard' I slipped my fingers into her pussy, it was already soaking and started to finger her roughly - she began to moan. After a few minutes of this, I slide down the bed and found her shaved pussy with my tongue - her moaning increased until she was almost screaming. After a few minutes of her panting and screaming, she said 'I want you in me - fuck me hard' I slipped into her soaking pussy, burying my cock as deep as I could, then began to ram hard into her. After several minutes I could feel myself getting close, so I pulled out but all she did was scream 'fuck me, dont stop'. 'I'm gonna cum' I said, 'its okay' Gemma said 'cum in me, fuck me hard' I slipped (or rather rammed) it back in and carried on fucking her hard. After a minute, we both came together. The feel of my cum pumping deep into her womb, made me orgasm more intensely (me wife hates not using a condom). We collapsed together and lay there for a while, with me still inside. Gemma then said 'I enjoyed that, you're going to do that more often' 'What about Steve' I asked. 'Fuck him,' she said 'he's just cums and doesnt allow me to, and then her always ways to use a rubber. I love to feel the cum in me, gets me so horny' We lay there for a while, before getting showered and dressed, after lunch we kissed and I fingered her before I left to do some work. When I saw her at the school later that day, we didnt really talk as she was in conversation with a couple of mums - although they did both look at me and smile. I wasnt sure if she had said anything, but the other mums seemed more friendly! We have been seeing each other during the day, once or twice a week since - its just (as she puts it) 'friends with benefits' and we both love it. Although I have on two other occasions carried out 'maintenance work' for a couple of other mums! Oh the joys of the school runs and stay-at-home mums!
