First I’d like to say this. As much as I would like to, I doubt I could ever convince my lady to do it. But I have a pervasive fantasy of getting multiple guys filling her pregnant pussy up after conception. Jekyll and Hyde these intrusive thoughts sometimes makes me wonder which is my true identity. 
A couple of years back I found a pregnant girl on craigslist on her 4th pregnancy. She was petite and had a boob job, the really cute young kind. She was going to move down south to Florida and wanted someone to live with when she got there. I wasn’t far away and we chatted for a while. She cheated on her bf and got pregnant but another guy and wasn’t planning on staying around for him to find out. She shared this fantasy of mine to have multiple guys fuck her pregnant pussy. She eventually got caught talking to me by her bf and was ready to leave. But I was traveling as a student and would be at a new location every month. I couldn’t see how I could do it. I bailed and regret missing the opportunity. She eventually found a decent guy closer to where she wanted to move. Anyways, thought I would share.
