Ok its back sorry for the late update but I kind of forgot about this until someone reminded me in a review, thanks PR Stella,,, lol ,,,, well its smutty smacked enjoy x.x.x.x.x Ok i know that some of you don't agree with the concept of this story but hey that is what fan fic is about getting them to do things that they normally wouldn't...

It had been two weeks since Stella had got married and two weeks since she has the most amazing sex with Mac, "Have a good first day back at work" Luke her new husband smiled as he kissed her cheek, "And say hi to Mac for me" he said before leaving the house, and leaving Stella to her naughty thoughts.

She had not seen Mac since that night as she flew on honeymoon early the next morning, pulling the towel around her tightly she walked towards the shower, just as she was about to step under the warm water she heard a knock at the door.

"Don't tell me you have left your keys again" Stella smiled half expecting Luke to be on the other side, "Mac" she gasped when she saw who the visitor was.

"What are you doing here" she smiled before opening the door wider to let him in, "I saw Luck leave and I wanted to see you before you started work, how was the honeymoon" Mac asked as he stepped inside and watched as Stella closed the door.

Leaning her back against it she looked at Mac, "It was Ok just relaxed and done some sightseeing" Stella replied.

"Did you have amazing sex" Mac asked as he took a step closer to Stella, "Mac you can't ask me that" Stella replied a little shocked.

"Ok I won't" Mac grinned as he stood in front of Stella, tracing her bare shoulders with his fingers she closed her eyes and sighed, "Mac I'm married I can't" Stella mumbled as Mac kissed her neck.

"You where married that night also and you choose to spend your wedding night with me rather than your husband" Mac replied as he looked into her eyes.

Gently puling at the towel, Mac dropped it to the floor exposing Stella's naked body to the cool morning air.

Gently placing his warm hands on her hips Mac leaned in to kiss Stella on the lips, it was slow at first but soon heated up, "I was just going to shower fancy joining me" Stella smirked as she looked at Mac, "Lead the way" came the reply.

Soon they were both undressed and under the warm shower spray, "I have missed you" Mac mumbled as she traced kisses down Stella's body.

Reaching her inner thighs Mac traced kisses along it until he reached her wet sheath, gently lifting her leg over his shoulder he inserted his tongue, "Mac so good" Stella moaned as he flicked the soft flesh causing her to buck towards his face.

Just then the front door opened and closed, "Stella honey I forgot my wallet" Luke yelled threw the apartment.

Mac didn't stop what he was doing he ignored Luke's voice and carried on pleasuring Stella, "Ok I'm in the shower I will see you tonight" Stella replied as best she could without moaning aloud.

On hearing the front door closed she looked down at Mac who was looking up at her, "We are so bad" she moaned, just then her juices cascaded down Mac's fingers and her legs.

Kissing his way back up her body Mac held her until she stopped trembling, gently turning her around he bent her forward and slipped his cock deep within her.

"Mac fast please" Stella sighed as she forced herself back towards his thrusts, grabbing her hips Mac plunged deep into her causing her to moan, soon they had a mind blowing orgasm and screamed each other's names.

Leaning forward Mac kissed Stella's back before taking his self out of her, "Missed you" he smiled kissing her lips before climbing out of the shower, getting dressed he watched Stella wash herself down, "See you at work" he smiled as he leaned in to kiss her lips again.

(A few weeks later)

"Mac I have some news" Stella said as she stepped into his office one afternoon, looking up from his desk Mac looked at his partner friend and sex buddy, "What's up" he asked as he stood up and walked towards Stella, "I'm pregnant" she mumbled before tears fell down her cheeks, "Oh" was all Mac could say in reply.

"Have you told Luke" Mac asked, shaking her head no, Stella looked at Mac, "I needed to tell you first" Stella replied.

"I have no idea who the dad is" Stella confessed, as she started to shake.

"Its Ok I will support you, and I'm sure Luke will, but if the baby is mine I would like to be involved" Mac said as he hugged Stella.

"Of course" Stella replied with a small smile.

"Id best get back to work" she said before leaving the office.

Taking a seat behind his desk Mac had a huge smile on his face, "I might be a daddy soon" he thought, of course the situation was not ideal but he loved Stella and he knew deep down she loved him and if the baby was his they could be a family.

(2 days later)

"Hey Mac you hear our news" Luke grinned as he had one arm around Stella, "Yes Stella said congrats" Mac replied as he plastered a fake smile on his face and shook Luke's hand, soon the whole lab where congratulating Stella and Luke on the baby news, Mac stood on the side lines and watched the love fest, glancing at the corner of her eye Stella saw Mac and felt her tummy tighten, this situation was mixed up, but she knew that even though she was pregnant and with two possible dads on the cards, that she would not be able to stop having sex with Mac no matter how much she tried...
