A contest of sorts

"You girls are such good sluts. I don't know if I can choose." Rachel and Sharon look at each other, worried they won't get to experience the joys of being heavily pregnant with your children. "I know!" you exclaim "Why don't the two of you lie down next to me and I'll finger your slutty pussies. Whoever cums first loses."

Rachel and Sharon seem thrilled at the idea and eagerly lie down on either side of you. They spread their legs to give you better access to their needy pussies. You slowly start to finger them increasing in speed. Rachel tries to look nonchalant , but she's clearly holding back moaning. Sharon however is quickly losing the battle, making adorable little sighs as you slide your fingers out of her wet snatch. You progress on to the clit and now Rachel is sighing too. They both look like their going to orgasm any minute.

As a final finishing blow you talk about how sexy they'll look knocked up, how their skirts will stretch and their boobs will grow, how after they pop out this one you fully intend to put another one in their so that their wombs are never empty for too long...

As you say this last line Sharon screams out her orgasm. Rachel follows seconds later. It looks like Rachel is the winner. How does she claim her prize?
