Sarah Calvados had been planning her husband's birthday surprise for the past two months and nothing, not even a call from the hospital in the middle of the night, was going to stop her from giving her husband the ultimate present for his 50th birthday. Tonight, the birthday boy got to make the calls and Sarah was willing to do whatever Brian asked of her. Even if he wants to take her hard and unprotected.

Excerpt:

“Come up here,” he commanded. She smiled as she stood up and straddled him. Brian took his time unwrapping his present, running his palms over her curves and massaging her flesh as he undid each button. He smirked at her surprised yelp as he pulled on the elastic of her lingerie and snapped it against her skin before tugging the flimsy bits of lace off her body.

A shiver of excitement shot up Sarah’s spine as her husband pushed her down onto the tiny cot in the on-call room and hovered over. He looked strong and virile, ready to conquer her body.

Sarah was more than ready to be claimed. She knew that he wanted to mark her for the world to see. She already walked around work covered in his scent, but to have her belly swollen with his babies would make it clear to everybody that she belonged to him.
