My stepfather and his wife (POV) call me into the kitchen one day after school. They've had a hard time conceiving, and they want me to be a surrogate! I'm appalled since I didn't agree with their marriage after my parent's divorce, so I lay into both of them, berating them to make them feel guilty. I storm to my room. Later, I find them in the bedroom and tell them I'll be a surrogate, but with some conditions. They pay for my college in full, I get a new car of my choosing with gas included, I get a shopping spree and - they start to get excited but I cut them off- And I get to pick how to be impregnated. At first they don't understand, but I explain I want it done naturally, not in a doctors office. I want my step-dad to cum inside me. They agree hesitantly and I take off my robe revealing lingerie and am ready to start- I'm ovulating after all. My stepdad's wife tries to leave, but I don't let her, I want her to watch her husband cum in me. She reluctantly sits and I make a big deal about how excited my stepdad is, how good his penis feels in my mouth and eventually inside me. I berate and humiliate her for being such a bad sexual partner for him, since he's so happy to fuck me. I face the camera first as I mount him, and then do reverse cowgirl right when he's about to cum. He cums a big load inside of me and it feels so good to be impregnated. The 'woman' storms off ad I yell after her, humiliating her some more. I then look at my stepdad as I put on my robe and reveal I forgot to admit I was on birth control, so we will be having to do this monthly. I hope he likes fucking me in my new car he's buying. And then I trot off, fun of cum and happy.
