Centaur Lover

Stev and Leighla have a most unusual relationship. He's a human and she's a centaur but they're in love. The only thing that complicates their lives, beyond the obvious interspecies problems, is Leighla's desperate desire to have a child. Stev can't do that for her, but he's certain he can find someone who can.ADULT READERS ONLYThis 10, 000 word story contains explicit sex between humans and centaurs.
All characters are 18 or older. Excerpt:"How open-minded do you want to be?" she asked him. Stev put on a brave face, partly because he had to but mostly because he wanted his lover to be happy. "I'll be as open-minded as need be. I'd be happy to have you bred by anyone who can give you a child."At first Leighla didn't know if she was thrilled to hear his words, or frightened at how easily she was going to give in to them.
The temptation was too strong. She knew she was going to say yes, so she broke it to him as easily as possible. Leighla folded her four legs beneath her body which brought her down to the level of Stev's waist. She locked eyes with the only being in the world she truly loved before asking, "You'll let me have sex with another centaur?"His smile was deep and warm and honest. "If that's what you need and what you want."It was exactly what Leighla needed and wanted.
