First Kiss and First time

Stella and Mac over the past few years had been denying their feelings for one another. Between the secret smiles, flirting and the old accidentally brushing hands. Mac spent most of that morning pacing his office waiting for Stella. She was someone that he depended on over the years and began to fall in love with her. He fell in love with her smile, laugh and especially her green sparkly eyes. Her eyes were what showed her emotions soft when she was happy, misty when she was sad and piercing green when she was angry. Stella was making her way to Mac's office and could see him pacing his office maybe for her. But this was Mac, Mac who hardly showed emotions only to her and not about her. Stella always loved Mac but over the years that love ran deeper than any other feeling that she had felt before. Before any of the other men in her life this was more a sense of pure love an intense emotion that took over her body when she was near him. Stella opened the door to his office Mac stopped pacing and turned to face her and smiled at her.

"Morning" she smiled

"Morning Stella" he replied, "I want to ask you something I haven't had the courage to ask you"

"What?" she questioned.

"Would you like to go out tonight," he asked his eyes never leaving hers she looked into his soft grey eyes she had grown accustom to.

"Like a date?" she asked then looked at him "I mean"

"Yes like a date me and you" he cut her off with.

"Sure" she replied quickly

"Great" he smiled before he had a chance to reply his phone went off and he looked down at it. "Trace" he said and she nodded they both made their way together. They worked on the same case as usual, each time sharing a glance and smiling both thinking about later on.

When Stella was in the locker room Mac walked in at watched her place her badge and gun with its holster in her locker. He looked at her from behind looking at his view.

"Mac if you plan on checking me out whilst I'm not looking you are seriously wrong" she turned around and stepped forward but Mac was gone maybe she was wrong. A second later Mac appeared from behind her and slipped his arms around her waist and whispered "Not all night and remember I'm a marine much better at being discreet"

"Oh really" she countered and turned round to face him and slipped her arms around his neck and smiled at him.

"Yes' he replied

"Well I think" she carried on removing his tie "that marines are very sexy" she laughed and threw his tie on the bench and wrapped her arms back around his neck again. He leaned for slowly waiting for her permission. Stella moved forward with him and their lips met for a soaring kiss. The kiss was slow and intimate she pushed him so he was backed against the lockers. Stella pulled away and waited for her breathing to return and the whispered "I think we should take this some where else"

"You sure I mean I don't want to rush you but we haven't even dated" he smiled

"Mac it feels like we've dated for years I've waited to long for this" she replied

"Me too" he whispered

"The let's go" she said as she pushed her locker shut and pulled him by the hand out of the locker room.

Once they reached Stella's inside Stella's apartment it was war between the to of their mouths lost in each other. Once they reached the bed they were lost in taking each other's clothes off. Stella pulled his shirt off and began to kiss the scars on his chest and he groaned as she smiled. Mac claimed her mouth in his again for another kiss while unbuttoning her shirt revealing her black and red lacing bra with a bow in the middle Mac made his way down he neck while pushing her on the bed. He made sure he was on top and that she was underneath he made his way down her neck kissing her down the bottom of her stomach until he reached her trousers and un buttoned them and pulled them off until she was just in her underwear her whole set matched and he smiled. He kissed her stomach and began to suck it leaving a red mark as she smiled towards him she pulled him back to her mouth. She then moved down to his trousers and undid them leaving him in his boxers and rolled him over so that she was on top and moved down to his neck nipping it to leave her mark. All that was left was to remove the last bit of each other's clothing. They ended up removing themselves Mac rolled her back over to make sure he was back on top of her.

"You ready" he whispered.

"Yes" she smiled and kissed him and moaned. Both came together then Mac moved into slowly and Stella had to kiss him so her scream was muffled by a moan and dug her nails into him back and cried out.

"I love you," he whispered as he moved into her again.

"I love you too," she rasped and moaned they rolled around together on the bed still committed Mac moved into her again she dug her nails in his back leaving little cuts. Till it climax till they slowed and pulled apart still kissing one another.

"I love you baby" Stella spoke as she rested her head in exhaustion in his chest and smiled.

"I love you" he breathed and kissed her on the top of the head both fell into a blissful sleep. Knowing that tomorrow would bring a different day and night.
