I've posted on here before (20th June and 21st July), this is the next installment of the saga. Sarah is the 27 year old temp that I've been fucking in work - usually in the shower room, or on very rare occasions just before work when her boyfriend leave early. The sex has been great and very adventurous - fulfilling each others fantasies. I told her once that I'd never had a 3sum and a few days later when her boyfriend was out with his mates, she called me and told me 'get round here quick - it's urgent'. I made an excuse at home and went round there. When I knocked, the door opened and I stepped in, the door closed and she was standing there naked - she kissed me and said 'strip off, count to 30 and come up, I've a surprise for you'. She ran up stairs as I stripped, my cock almost instantly hard, I counted to 30 and went up. The bedroom door was closed, I pushed it open and there sitting on the bed was Sarah and another girl, both naked. It turns out that her friend, I will call her Beccy, was visiting her mum for the weekend. Beccy moved up north when she married a guy, and thought she would visit Sarah. When I told Sarah of my lack of a 3sum, she said 'I'll see what I can do' - turns out Sarah is one for experimenting and has had sex with Beccy many times in the past. Sarah allowed me to fuck the pair of them - and to my delight, they both hate condoms, so I got to shoot my load into their pussy's. The other week, Sarah told me that she had got a call from Beccy saying that she was pregnant and she wasn't sure if it was her husbands or mine, but she was keeping it as her husband is delighted (obviously he doesn't know about our fun evening). When Sarah told me, I said that she would have to arrange another visit from Beccy while she was pregnant as I have a thing for pregnant women and would love to fuck her with a swollen belly. Two weeks ago, while we were having lunch, Sarah said to me 'I'm late' I asked 'how late?' She replied 'nearly 2 weeks, I'm going to do a test tonight' The next day Sarah sent me an email saying the test had been positive and she was going to the GP to confirm. She also said her boyfriend had found the test kit and thinks its his and if its confirmed, he wants to keep it. So now both the girls that I have fucked are pregnant and neither knows if its mine or their partners! But the bonus is, they have both agreed to have another 3sum when their bellies are swollen! I'll look forward to fucking the pair of them in the next few months - Sarah has a high sex drive and said that the increase in her hormones are making her even more horny! So it looks like she want to be serviced even more frequently!
