You saw an ad looking for the perfect sperm donor, and decided to reply and go to the "interview". You get to the interview, which happens to take place at the apartment of the woman looking for the sperm donor. Once there, she tells you that she is looking for the perfect man to donate his sperm to her. She doesn't expect you to be involved with the pregnancy or anything afterwards, but she wants to make sure that the sperm she is getting is superior, premium sperm. And to find that out, she needs to talk to and interview candidates in person. Then it's time for the interview. She asks you a series of questions, ranging from your health and medical history to lifestyle. The questions get very personal, but you are completely willing to answer all of them truthfully. After you answer all of her questions, you can tell she is clearly impressed. But that's not the end of the interview. She tells you that this next part is a bit different, but it is necessary. She needs you to strip down completely naked for her so that she can see you body in it's entirety. You do so, and at this point she cannot contain her excitement. And perhaps even her horniness? She then tells you that she wants to get pregnant the "organic" way. Not in a doctor's office, but through good old fashioned sex. And, as luck would have it, she took an ovulation test this morning and she is currently ovulating. Her pussy is wet and inviting. Her womb, her body, is ready to be impregnated. You could do it right now. As she is saying this she has stripped completely naked, and seeing her body, that body that is just begging to have a huge cum load inside of it, gets you completely rock hard. How can you say no to this?! She has you lay down on the sofa where she climbs on top of you and slowly lowers herself onto you, guiding your cock inside of her tight pussy. She bounces up and down on top of you, riding your cock perfectly. All the while, telling you how perfect your cock is and how she can't wait for your huge cum load. She stops for a bit, wanting to edge you so that you build up as much cum as possible before cumming deep inside of her. She wants you to be able to fill her up to the point where your cum is leaking out of her. After riding you for awhile, she has you get on top. When you cum, she doesn't want a single drop to spill out of her and it's also the best position to get pregnant in. So, you get on top of her and thrust into in that position. You're going to keep thrusting into her, pleasuring the both of you, until the two of you cum together. Until you cum deep inside of her, against her waiting womb, impregnating her.
