Jade Bleu 
Bred by a Billionaire 3: Virginia (Unprotected Billionaires, #4) [EPUB ebook] 

Fertile billionaire knocked me up my first time! 
Alan was determined to mark a virgin with his seed and leave her not only utterly satisfied, but pregnant as well—and he had some hot, freaky theories on how best to do it. I was so eager for the money that I didn’t ask for the dirty details…I just wanted him to deflower me and make me his hot mama. Little did I know what all he had in store while he was breeding me.
An erotic short featuring first time deflowering and fertile fun with a billionaire.
