We’ve been having an affair for a while now, but we ALWAYS make sure to be careful and use condoms. But it’s a few hours before guests are due to arrive at our house for a stepfamily party and… god… you know I can never say no to you, even if I know the risks. Maybe it’s my fault for playing with fire by commenting about how you could get me pregnant as we fuck. But I’m bent over, being made to cum on the one cock I should never have… you can forgive me for getting lost in the moment. Hurriedly getting dressed after we fuck, you say you’re feeling funny. I don’t think anything of if until I notice you’re sitting down… and your belly is MASSIVE. What the fuck?! Where did that even come from? You look… no. There’s no way you’re pregnant. Not that quick and not that HUGE. But… when I touch your belly, I realise that the movement I was so familiar with, with you, is happening right under my fingertips. I’m horrified, shocked, angry? How on earth did this happen?! We don’t have time to process is, and have to head downstairs to welcome the guests. Foolishly, I’m hoping they don’t notice… but it is pretty hard to hide a belly THAT huge… Yet I try anyway, pulling your shirt down as much as I can. It’s obvious I’m nervous.. and then people start coming over. All female steprelatives. Your stepaunt. Your stepcousins. Your stepgrandma… at first, I’m hesitant to answer any questions, but eventually I adore showing you off, showing off your belly so everyone can have a touch and feel and yapping away about how proud of you I am… And when the guests finally leave, and you’re resting on our bed… I decide that I need to apologise for how rude I was to you and your massive belly when I first saw it. I massage my hands into your massive belly, oiling it up as I sweet talk you, telling you how proud I am and how much I can’t wait to support you… The following morning, my mood is exactly the same. I’m elated. I can’t wait to be stepDaddy haha! I’m already naked and take it upon myself to deal with your morning wood, seeing as you’re too big to reach. I suck you off, you just about see the tip of your cock over your belly, and ride you until… POP! Quick! Let’s get dressed! You need to go to hospital!
