Work Text:
When Dexter gets home he finds Deb in his office. She rarely goes in there so he's surprised to see her using his laptop. It's not what he intended but sometimes Deb is kind of a traditional wife. He makes most of the family decisions. And she often asks for permission to do things she doesn't need permission for. And she brings him drinks and snacks. And she doesnt mess with any of his 'stuff.' Work or otherwise. If he didn't know better he'd think she was avoiding leaving fingerprints.
He's tried to encourage her to keep him company when he works from home but she always declines. He thinks it reminds her of the aftermath of one of their early break ups. The time she ran from him and when he brought her back he took time off to help her adjust. Which involved her sucking him off under his desk. They haven't done that since and he files it away for consideration later. Now is clearly not the right time to suggest it because Deb looks drawn and worried.
"There's a podcast about you. A fucking podcast."
"What?"
She turns his laptop around so he can see that there is indeed a podcast all about the bay harbour butcher. Complete with a profile and photos of Doakes. He doesnt know what to say. It doesn't matter because she continues.
"Turns out thousands of people think Doakes was framed. And that the real killer is still out there."
Sergeant Doakes. The guy who hated Dexter and saw him for what he truly is. And who, Dexter suspects, had a thing for Deb. Doakes had watched Deb almost as much as Dexter and although he complained about being saddled with a rookie, he held doors for her and she met his family. Dexter thinks Doakes might have liked Deb a bit too much. Not that Dexter can blame him for that because he has a thing for Deb as well.
In another universe, one where Dexter didn't give Doakes the creeps he might have been a good match for Deb. They could have dated maybe got married and had a bunch of foul mouthed kids running around. Instead Doakes got himself killed and Dexter got Deb. He prefers this universe.
"Where's Harrison? " Dexter asks.
"Playdate at the Barkers." She rubs her eyes. "Its never going to end. It's going to keep coming back and back. Everything we've done."
Dexter has to stop this spiral before it starts. Although he has to agree. Every time he manages to get them on an even keel something happens to set them back. Just when he thinks Deb's finally adjusted and they've turned a corner something kicks her off again and he's sick of it. He can't keep doing this every couple of years. It's not healthy for either of them. Or their marriage.
"Deb. Nothing has happened. It's just a stupid podcast. How did you even find it?" They both avoid murder shows of any kind. Deb because she feels guilty and ashamed and Dexter because most of them are about people who got caught which he finds depressing.
"They were talking about it at book club."
That fucking book club. He actually encouraged her to join it because she needed to get out of the house and make some friends. His theory is that she can't dwell on their unique situation if she actually has things to do. Just as Dexter distracts himself from the need to kill by doing Debra as often as he can manage. Deb uses book club and hes kind of relieved because if Deb was as horny as he is they'd never get anything done. And they'd have a whole bunch of kids.
Not for the first time Dexter considers knocking Deb up. Then she wouldn't have time to listen to podcasts about him. He'd have to talk her into changing her birth control. To be honest he's surprised he hasn't got her pregnant yet. They've never particularly used condoms and they fuck every night. Most of them in ways that don't prohibit getting pregnant. Come to think of it. Her lack of pregnancy needs investigation. But not now.
He takes her face in his hands.
"Deb. We're fine. We're safe. Nothing has changed."
He can see that shes struggling to speak. That she needs to ask him for something but can't get the words out. And he knows exactly how to help her. He remembers the weeks of calm after the last time they did this. How Deb had settled down into obedience and how that had patched together the torn and sore places inside him that had been left by the lake incident and then her escape attempt.
He guides her out of the chair and takes her place."it's okay Deb it's okay." He keeps repeating it as he lowers her to her knees. He unzips his pants and even though he's not hard he feeds his cock into her mouth.
"Good girl. You're so good for me." He strokes her hair softly. "You can trust me to keep us safe, Deb. I won't let anything happen to you or Harrison."
She's looking at him with sorrowful eyes and her mouth stuffed with his dick. Dexter usually likes it hard and rough but there's something appealing about having his broken beautiful sister on her knees just keeping his cock warm in her mouth. They should do this more often. It soothes Dexter's need to be in control and the distraction serves to quiet the noise in her brain. Dexter leans back and lets himself enjoy her submission. They stay in place for long minutes, he can hear traffic noise and bird song outside and he can feel Deb's breathing become slow and steady. His own breathing slows to keep pace and he lets himself relax enough to almost fall asleep. He's surprised that Deb has stayed still this long. She never lets him keep any part of himself inside her once they're done. Not even his fingers. So this is a rare treat. One he doesn't want to squander.
Her knees must be hurting so he gently pulls his half hard cock out. That surprises him as well. This is sn unusualy afternoon. It doesn't normally take him this long to get going. It must be the Doakes effect. For most of the time he'd known Doakes he'd practically been celibate. It must be a pavlovian response. Doakes would not have approved of him fucking his sister. Even Deb seems surprised by his semi. Dexter smiles and helps her up and into his lap. He loves this bit. Loves the feel of his sister close to him and leaning on him. When Deb needs him is when he feels most alive. And not just when she needs him to make control but when she needs him to comfort her as well. Dexter rarely feels regret and in quiet moments like these he knows he made the right decision to bring them here.
Deb shifts around on his lap and for once she makes the first move. She rests her hand on his throat the way he does with her. And she snakes her other hand inside his pants. Dexter exhales. He gets hard almost instantly, always does when she initiates. He fumbles in his desk drawer for the lube he keeps in there. For the times he needs to jack off when Deb isn't there. He's kind of glad she doesn't come into his office, sometimes he jerks off in there if he's in the mood and she's 'too busy for that right now Dexter. Jesus christ what the fuck is wrong with you. Asshole.'
Today Deb takes the tube from him without comment but she's got her knowing little sister look on her face and she's going to use this against him later somehow. She dollops too much into her hand which makes him realise they never really use lube together. His cock twitches at the thought of how when they fuck she is usually wet. And he gets harder when he thinks of the times he's fucked her dry. And the noises she makes when he does. The hurt, pained sounds that he can pull out of her that would make any other man stop but thwtsspur him on.
He's so lost in his fantasises that he jumps when she touches him. She starts with very soft gentle strokes. All the way up and down his shaft. She coats him with the lube and then twists her wrist to get a tiny bit of friction. Dexter drops his head back and and lets her work. The feathery soft strokes across his skin are nice. Gentle. Vanilla. She moves her hand almost absently like she's stroking a friendly cat. There's no firmness in her grip at all and just as it's becoming tedious she adds more pressure and runs her thumb across the head and catches the slit with her nail. That's new. Dexter looks up with interest. He catches her eye and knows she did it deliberately. She goes back to the torturously slow slick moves and then does it again. A little harder this time. He didn't know a hand job could be this interesting. She normally uses them when he's horny and she's busy, as a sort of quick and dirty placeholder for a proper fuck.
Deb presses the heel of her hand into the base of his cock. Harder than she needs to but after all this time she knows how rough he likes his rough and tumble. Dexter starts panting as she squeezes and twists and digs into his dick. The pace is still slow but she's putting more pressure in. Leaning heavier and holding him tighter. She keeps going, never letting him get used to the rhythm and he's getting close when she scratches her nails down his entire length and he's sure she's left marks.
"Deb" he just about pants it out and in a flash she's on her knees with her top off and he's coming on her face and tits.
"Fuck." She almost never lets him do that either. Deb complies with most of his requests quite placidly but she'll barely tolerate his come on her skin and in her hair. Dexter likes to paint her face this way. It's so dirty and it reminds him of blood spatter. There's no way she'd let him but sometimes he fantasises about putting Deb on his table and coming on her. Just to see the difference between blood and come in that environment. He thinks that if he ever suggested that, it would be his blood that was used.
Dexter kisses Deb and flicks his tongue over her lips to taste himself. He doesnt do it a lot but he's done it enough to make sure he eats enough pineapple.
Deb lets him lick her for a moment longer and then gets off him and goes into the bathroom to start the shower. He got it in her hair as well. He follows her and just watches her clean off. She used to shut the door on him to try to get some space, to give herself the semblance of privacy. Now there are no locked doors between them. Dexter has taken them down one by one and now there's nowhere for her to go except straight to him. He feels a soothing calmness in his blood. Putting Deb on her knees when she's anxious makes her mind calm down. Seeing her on her knees has the same effect on him.
Doakes would never have understood that.
