Summary
Rio breathed her in again and let out a low moan. “Agatha…” she groaned, the soft breath that escaped her lips caressed the shell of Agatha's ear, sending a shiver down her spine. The way the alpha reverently whispered her name, taking ownership of every single fucking syllable. The omega's head lolled on to Rio’s shoulder, her eyes rolled back, unable to push down the feeling of pleasure that bubbled up within her.
Rio made her name sound like home.

Summary
Dr. Vidal takes the wand and slowly slips it inside of her. It goes in seamlessly. Agatha’s neck feels tense, and she tries to lean her head back to loosen things up.
“Are you sure you’re okay?” Dr. Vidal looks up at Agatha with big baby brown eyes. “If you’re anxious, we can stop, or I can give you a pheromone patch—”
“I’m perfectly fine,” Agatha snaps, and then she blurts out, “I’m not nervous!”
Dr. Vidal just blinks at her owlishly, and Agatha presses her lips together. Fuck. What if the doctor connects the dots? Agatha isn’t nervous, just embarrassed. It isn’t her fault she encompasses a physical body and, by objective accounts, Dr. Vidal is attractive.
And smells good.
Whatever.
“Okay,” Dr. Vidal says softly. “My apologies.”
_____OR, Agatha finds herself in a predicament: she's pregnant, single, and in her forties, and the only gynecologist that is qualified to help her is alpha Dr. Rio Vidal.
Written for Agatha All Along Week, day 7: breeding ;-)
