You head into step-Mommy's room to discuss moving out again. You think it's time you and your GF get your own place together, but clearly your step-Mommy doesn't agree. She's upset you'd even bring it up right now, especially because ever since she got pregnant your step-Father has been working so many long hours to make sure everything is ready. She tells you that she needs you to stay home so that you can help when the time comes, but you get upset and give her attitude. step-Mommy snaps and confesses that you have to stay home to help because it's YOURS. That's right, all those times you came inside step-Mommy have resulted in this.. and she's been lying to your step-Father saying it's his so that he will raise it. You're shocked but also turned on at the idea of step-Mommy's growing belly being the result of your cum. You start to get hard and she notices and begins teasing you with her big pregnant belly. She had no idea you were into pregnant women, but she sure has been horny ever since she got knocked up. Your step-Father can hardly keep up with her sex drive! Why don't you help her out? Give her what she needs? step-Mommy gets on top and rides you with her belly in your face, then she begs for you to get on top and cum inside her again. It's not like she can get pregnant twice! Maybe you won't move out after all..
