A/N: This is my first smut so I'm sorry that it's kinda awful.
I don't own the characters, which sucks, but I do this for fun.
Enjoy :)
Seething. There was no other way to put it. No one kisses your girlfriend and gets away with it. It happened so quickly you nearly missed it. But you didn't, and now she has a lesson to learn. She noticed the shift in your demeanour almost instantly. You make it into the kitchen of your house before she questions you. You barely let her get your name out before your lips are on hers and you're pushing her into the counter. Pulling back for breath a sigh of "Maura" escapes her. You quickly silence her, nipping and sucking at her neck, making sure to leave a mark. You soothe it with your tongue and make your way up to her ear, whispering "you are my girlfriend. No one else gets to kiss you, even under the pretence of a case." She nods in silent approval and you continue your assault, moving along her jawline, her neck, her mouth, anything you can get to. Making sure her feet are firmly on the floor, you kick them apart with your own. Her gaze is firmly fixed on your hand as you deftly unbuckle and unbutton her pants, slowly sliding three manicured fingers in. You press yourself flush against her and her head drops to your shoulder as you glide in silky warmth.
"You like it when I'm possessive, don't you? It turns you on when I'm jealous," you roll her earlobe between your teeth and she moans in pleasure. When her breath catches in her throat and you know she's not going to last long. You increase your pace and she's soon crashing over the edge, trying not to knock you down. When she regains her composure you set her back upright and turn on your heel, heading towards your room. "It's your choice whether you make me jealous again or not," you say, turning slightly to face her and you set off again. It's not long until you feel her presence behind you. "If that's going to happen, I might consider it."
