I told you a little while ago about the affair that I have been having with one of the teachers at my son's school, Gill is in her late 30's, only 5 ft tall but has massive 38E tits, her figure is 'of the ample size' and suits her height and bust. Gill and her husband lives in a large detached house about 15 miles from my house, the garden is really large, she said that she specifically had fast growing trees planted all around the edge in order to stop people seeing in as she likes to spend most of the day naked when she's at home alone. At the end of her garden, hidden behind a 6 foot fence and a screen of trees there is a large swimming pool and patio area with a pool house and jacuzzi. They have been married about 20 years and she said that he doesn't pay her much attention sexually, so she has in the past played around, but said that she was looking for something more regular until we started. My wife likes to take the kids away to our caravan every school holiday and at weekends when the weather is nice, being self-employed means that I must work to earn the money so I'll stay at home. A few weekends ago Gill called me and said 'Ann (my wife) told me she was taking the kids away this weekend when I saw her at school yesterday, if you're not busy Stuart is away for a couple of weeks.......' I knew exactly what that meant. I put my stuff in the van and drove over to Gill's. When I arrived I called her, as usual just in case someone has popped round since we spoke, she said 'I'm round the back, gate's open' I parked up the van and walked into her garden. As I walked around the side of the house she was sitting on a lounger naked, drink in hand, her lovely 38E tits glistening in the sun from all the sun lotion she had applied. All she said was 'help yourself'. So I walked over to her and kissed her, as I did I slipped a couple of fingers into her trimmed little pussy, she jumped and said 'fucking cheek!', I meant help yourself to a drink' Five minutes later I was laying on a lounger naked, drink in one hand and one of Gill's lovely large nipples in the other, Gill was knelt to the side sliding her lips up and down my rock hard shaft like a pro. After a few minutes of her working her magic on my cock I was shooting my load into the back of her throat while she swallowed all I could give her. When she finished, she carried on licking my shaft clean until it went limp, she sat back on her lounger then she said 'you can return the favour', so I knelt at the foot of her lounger, pulled her down the bed towards me and spread her legs exposing her juice pussy. As I slide my tongue in between her lips, I could immediately taste her juices, I slowly slid my cock in and out of her pussy as she started to moan, then I found her clit with my tongue and slide a couple of fingers inside her. Gill was moaning as I fingered her harder and harder, my tongue flicking and rubbing her clit. Within minutes she was cummin all over my face as I tried to lick what I could. She pulled at the back of my head and forced my tongue deeper into her, my nose rubbing her clit while my tongue pushed deeper onto her. After a minute of so, she collapsed panting, then said 'fuck, that was good. Stuart has never gone down on me' After she recovered, Gill stood and said 'I'm going for a swim', then ran off naked down the garden. I followed. Gill was already in the pool as I walked around the fence, her lovely large tits bobbing up and down in the water. I laughed and said 'you've no danger of drowning' . She splayed water at me and said 'cheeky fucker, get in here'. I jumped in and swam over to her, we kissed heavily for a while then she swam over to the shallow end and sat on the steps. I followed and sat beside her, then she said 'let's get you hard again, you're going to fuck me here' and she started to work on my limp cock with her hands. Within minutes she had worked her magic and I was hard again. Gill turned around, knelt on the steps and spread her legs, then rested her hands on the side of the pool, her lovely arse pointing straight at me, her pussy clearly visible. She looked over her shoulder and said 'fuck my arse'. I moved over to Gill, knelt behind her and slide my hard cock up against her pussy lips and began to slide in, Gill moved forward so that my cock slipped out, then she said 'I said, fuck my arse'. I guided my cock towards her hole, she re-positioned herself so that her cheeks spread and I had better access, then she said 'get me wet before you try to put that in', so I slide a couple of fingers into her pussy to get them covered in her juices and then rubbed then all over her hole. Her arse seemed tiny, I thought there's no way I'm getting in there. But if that's what she want's. I rubbed my hard cock against her hole, stopped the tip on the rim, then I slowly pushed. It was hard at first, but I pushed a little harder then pulled back, spat a little onto her hole, then pushed my cock harder in each time. Gill was moaning each time I pushed, every time I pushed I felt her arse muscle relaxing, then one more push and I felt it give, my cock slid in and Gill gave a moan. Gill said 'don't move, I want to get used to you being in me'. So I waited. Then she said 'fuck me slowly'. I did what I was told. When I first fucked Gill's pussy she seemed tight, but her pussy was nothing compared to her arse - this was really tight. Every time I pushed into her arse Gill moaned and I could feel myself getting closer, it must have been because she was so tight. I started to build a slow rhythm, pushing in and sliding out, Gill started to push back every time I slid in. I reached around her and started to play with her lovely large tits, rubbing, squeezing and tweaking her nipples - she loves her tits being played with. After a few minutes Gill said 'cum in me, fuck me hard, fill my arse with your cum'. I pumped harder. Then she said 'fill my dirty hole with your juice, I want to feel you cock pumping into me, pump me, fuck me, cum in me, finger my pussy', so I slid my hand down between her legs, slipped two fingers into her wet pussy and began to finger her, rubbing my fingers over her clit as they slid in and out. I shot my load into her arse a minute later. But I didn't go limp, her dirty talk obviously had an effect, so I kept fucking her arse and she kept pushing back as I slid in. Within a minute Gill moaned 'fuck I'm cummin, keep fucking my arse, keep fingering me, don't stop'. Her orgasm seemed to go on for ages. When she finally finished, she lent forward and my cock slid out of her, my cum running out between her arse cheeks. She said 'fuck, that was good, Stuart has never fuck my arse, he won't even finger it'. Then she got up and went to the pool house to clean up. When she came back, I did the same. We lay in the sun on the side of the pool for ages recovering, then Gill said 'I'm going to make lunch, then once you have eaten and recovered, you are going to fuck me some more or I'm going to punish you the way a naughty boy should be'. Gill has never spoken to me like that - being domineering. She then got up wand went to the house, she came back 10 minutes later with a tray of sandwiches. When we had finished Gill said 'let's get you hard again' - but I had already recovered and was as hard as I had ever been. Gill told me (more like an order) to lay on my back, which I did. She then straddled my hips and slowly lowered herself onto my cock, her tiny pussy stretching around my rigid member. When she had pushed all the way down, I could feel the tip of my cock pushing against her cervix, she pushed a little more and moaned,she sat there for a while then slowly lifted herself until she was almost off of my cock, then rammed herself down again, she repeated this about a dozen times or more, then rammed herself down and stopped, then slowly she began to rock back and forth, the tip of my cock rubbing between her cervix and g-spot. After a few minutes Gill was panting heavily and moaning, I grabbed her tits and started to squeeze the nipples, rolling them around between my finger and thumb. Gill was panting really heavily, I could feel myself building up to cummin, then Gill said 'fuck, I'm gonna cum again. Cum with me'. I didn't need to be asked, I was already on my way. Gill then let out on final deep moan and held her breathe as her orgasm hit, As it did I shot my load into her tight little pussy. She collapsed on top of me as I was still pumping into her, my cock remained rigid for some time as she lay on top of me, every little move either of us made made her shiver as my cock would rub her inside and set of what seemed to be an 'after shock'. We lay there for some time like that, me still inside her even though I had gone limp. Then she rolled off me and said 'That was great, I haven't cum that much for ages'. I left her house about 5pm. When I got home my wife called and asked if I had been busy, I just replied 'I had to sort out some blocked pipes earlier, nothing much'. Around 9, my mobile rang, it was Gill, she said that she had been horny all evening remembering what we had done earlier and wanted me to come over for the night. As my wife wouldn't be home until later on the Sunday afternoon, I had no problems with going, by 10:30 I was tucked up in bed with Gill sliding into her tight wet pussy again.
