And he's obsessed with getting me pregnant.
I go to Dr. Hayes's clinic for a routine appointment. I don't expect him to be there. Don't expect him to insist on examining me himself.
And I definitely don't expect what he whispers when his gloved hands are between my thighs.
"You're perfect," he breathes, his eyes dark with hunger. "So fertile. So ready. Your body is made for this."
My face burns. I'm trembling on the exam table, exposed and vulnerable.
"Made for what?" I whisper.
His jaw clenches. "To carry my baby."
I should run. But I don't.
Because he starts talking about ovulation cycles. About optimal timing. About how he could make sure it takes on the first try.
And my body betrays me, getting slick and hot at the thought.
"Let me fill you," he demands, backing me against the wall of his office after hours. "Let me breed you properly. I'll give you everything—every drop, every thrust, until you're swollen with me."
I'm so wet I'm shaking. So desperate I can barely breathe.
When he finally takes me on his desk, he doesn't use protection. And I don't ask him to.
"That's it," he groans, pressing deep. "Take it all. Let me plant my baby in you."
This is wrong. So wrong. But I want it. Want him. Want to feel his seed take root.
And he doesn't stop until he's sure it has.
