Persia

Ordinarily it would have required some sort of effort to get Persia ready for a round of sex with at least some foreplay but what ever that scent was you dropped earlier has Persia wet and ready right this second. Persia has had her cloths off since you started fucking Alexis so all it takes is for her to position herself on the bed and she is ready to get some.

Taking Persia's legs you pull her closer to you and position your cock at her pussies entrance, Persia moans as your cock slowly enters her pussy and you begin to work it inside of her. Purring as you slowly fuck her Persia is enjoying it for sure but is curious why she cannot feel anything really different to how things are normally, Persia does not know you are running a small experiment with her. What you are trying to find out with this experiment is just how much concentration it takes to trigger this change or improvement to yourself as you have not really had it happen before, so what is the difference between you just fucking a girl, trying to help one get pregnant and really trying to knock a bitch up hard, as the differences are like night and day.

Persia of course only takes a short time to get what it is you are trying to do and gives you a rather put out look before simply sighing, " really Johnathan you are using me as a guinea pig, uh fine we really do need to understand this better I suppose but this had better end like how Alexis got it young man". Currently you have not been thinking of making Persia pregnant in the slightest but now you start to think about it, strangely just thinking about making Persia pregnant is not causing the change like with Alexis but you still feel if you cum now Persia will become pregnant. You just cannot explain how you know this but you do, its then that you remember just what you were doing when you started going all out with Alexis.

Fully envisioning Persia pregnant and with a full round belly, it is this that does the trick, your cock enlarges those extra inches and your balls begin to enlarge, as well as the scent slowly forming. Persia once again smells that wonderous scent from before and smiles as she realises you have found a trigger just as she feels your cock grow and breach her womb. Groaning as your cock slides into her womb without an issue even though it has gotten a lot bigger then what she is used to. Persia is now begging you to impregnate her while orgasming as your cock batters her wombs walls sending her into heaven, so you do with a smile on your face. Grabbing her tight by her hips you fully impale Persia on your cock and unload your balls in to her womb, lifting Persia up at an angle you prop her up with a pillow like Alexis and then kiss her tenderly.

At this point Persia comes down from her orgasm high, the first thing she does is say thank you the second thing she does is take a sample, proving she is always the scientist o matter the situation. "Now Johnathan what caused or allowed the change as you most defiantly got bigger during the session and you most certainly generated a much larger load then I remember having taken before".

Explaining what you had to do and the strange feelings you got while doing it Persia is writing this all down while on her back and honestly it is so funny yet so hot at the same time. Making her notes Persia is also talking to herself about needing to find a way to get a sample of the scent she was smelling as well as another set of samples from you when your not thinking about making a girl pregnant and the middle ground one as well. " So Johnathan who in this house would be willing to help with this, I need a sample from someone you have sex with while you do not think about getting pregnant, a sample from someone who you think of getting pregnant and we already have samples of you imagining the end product so to speak".

Cherie is easy for the first option same as Nicole and Darla will not say no to another go so as long as they are still around you can sort the samples out from then no problems.
