Over 20 years ago I was at Uni in Preston. There were rough enough tower blocks the other side of Moor Lane from the student halls I lived in. Preston is a great uni town and there was plenty of fun to be had with willing college girls. One day I was leaving the 7/11 store when a girl in her mid-twenties with a child in a buggy was in a bit if a state as a wheel had come off and she couldn't get it up the steps especially with her shopping and that she was almost 5 months pregnant. I offered to lift it for her and at the top offered to help her get home as the wheel was sitting on but still not secure. She agreed and thanked me. She lived in one of the tower blocks and it was a bit of a struggle but we eventually got to her flat. She asked me in for a cuppa and I said yes. Her son was asleep so she left him in the buggy in his room. She told me her partner was in prison for theft so she was on her own for the next few months. He was a repeat offender it seemed so was in and out a bit. After about 30 minutes chat I said I'd leave her to it and got up to put my mug in the sink. She came up behind me and put her hand around my waist at the sink and said can I thank you properly dropping it to my groin and grabbing my cock through my jeans. I turned around and said nothing as she opened the jeans and said she needed some affection as her hormones were making her horny all the time. She shoved her tongue down my throat and started wanking my cock, this was heaven. I grabbed her ass and was groping her all over when she went down on her knees and started to give me the best blow job I ever had. After a minute or so I had to get her to stop as I was going to cum. She took her top and bra off and that's when I got a good look at her round belly and big swollen nipples. I sucked on them as I shoved my hand down her jeans into her wet pussy. She came in seconds on my fingers and said she needed fucking. She bent over the counter and told me to fuck her, I didn't need to be told twice! I slipped my cock up her slowly and fucked her slow and deep for a minute or two as I could have easily blown my load. All the while I was rubbing her belly and squeezing her tits, this was heaven. She was moaning the whole time about how much she needed this and was cumming over and over again, stifling her orgasms as not to wake her son. I was no superstud so making her cum this often and easily was bloody brilliant. I told her I needed to cum so she told me to fuck her hard and spunk up her. I did as I was told and built up a head of speed and within a minute was cumming as hard as I ever had deep inside her. I stood there for a minute or so until my limp cock slipped out of her. We wiped ourselves clean and she thanked me again saying she could do with that again. I told her anytime and gave her my number. That night she text me after her son was in bed and I was back round for more, fucking for most of the night in a variety of positions. Oh to be 20 again! I was fucking her regularly over the next couple of months as her bump got bigger as did her tits and I couldn't get enough. Spooning her first thing in the morning was my personal favourite, with her telling me go on, help my baby along. It was so fucking horny. Her fella was due out when she was 38 weeks so I knew the end was near. When she was 36 weeks I called over after lectures as her 2 year old would be on his nap. When the door opened a rough looking skinny fucker asked me what the fuck I wanted. Her fella had been let out 2 weeks early that morning. Quick as a flash I asked him if he believed in Jesus Christ our lord and saviour and if he had time to talk about a new spiritual path? He told me to fuck off and closed the door in my face. I was sick as I knew things were over. She text me later and apologised as she didn't know but now had to stop texting me. I quickly replied I understood and wished her all the best. I saw her a few times in the coming year on the street, always with him and her buggies. I was hoping he'd get back to his old ways but he must have turned over a new leaf as she never text again. After that sex with women always lacked a bit for me. In the coming years I actually managed to pull a few pregnant women and it was heaven again. Usually they'd be out with friends but feel a bit isolated as they'd not be drinking. not getting it at home, feeling ugly (far from it) and not be going clubbing with their mates. Friends would never suspect they'd cheat, either did they themselves but after the friends would head off and they'd be waiting for a cab that's when I would make a move. Sometimes it was a quick blowjob, a couple came back to mine for sex before I would drop them home. One randy bitch I fucked a half a dozen times as she wasn't getting it at home so I gladly obliged. When I settled and married sex when my wife was pregnant was my favourite time, she used to joke that I must be a pervert always being so horny when she was up the duff. I used to laugh it off but I was. 4 kids has actually left her with a bit of a pot belly which she hates but I love. Rubbing it when I am fucking her doggystyle or spooning her always bring me back to that flat in Preston!
