Work Text:
Dean kisses Castiel awake on the last Saturday of the month. The omega stirs, burying his face into the pillow in protest.
"Caaas," Dean coos encouragingly. "I'll make you some coffee."
Dean only gets a grunt in reply, so he peppers Castiel's bare back with a few more kisses before shoving the covers off himself and slipping his feet into his slippers to head back downstairs.
Back cracking a couple of times as he stretches, Dean sets the coffee pot going before heading into the large alcove they have off the living room. It's what used to be the pantry, but when they moved in, Dean knocked it through and made it a smaller room off the living room for Cas.
It's necessary, every couple of months, that an omega get a good healthy clear out of their semen and slick gland. It keeps everything in good working order for when their heats hit twice a year.
Inside is a tall wooden cabinet, one that Dean was given by his uncle when they moved in, built specially for him, along with a matching ottoman with a soft blue leather seat. The ottoman is around knee height, perfect for Dean to work on Cas once he's presented on top.
The alternative is the clinic down the road, with white walls, a steel bench and unforgiving hands and tools that neither he or Cas appreciate, so after that one awful time, they've set themselves up at home to do it in private. In private, they can take their time and both enjoy the process.
Dean hears the coffee maker beep in the kitchen, so returns and fills two mugs with coffee — one with creamer and a sugar for himself and one with vanilla and creamer for Castiel — and heads back up to entice Cas out of bed so they can start the day.
Heading into the last of spring, it's warm enough that Dean just wears a pair of grey sweatpants as he stands over Cas. He's strapped his omega in well, his calves and forearms belted down and the metal hoop going over his back resting snugly over his sides.
Cas is facing the cabinet at the end of the room, with his ass facing towards the doors — for ease of use more than anything — so Dean rounds the ottoman and crouches down. He picks up Cas' chin in his fingers and looks Cas in the eyes. Already, as beautiful as Cas is, he's pliant and willing, having gone through this twice already this year. This is the last one before his first heat of the year and they have big plans to start their family when it hits.
Dean hears Cas' wolf rumble to his own, setting off a pleasant feeling in his chest and filling the room with the smell of lavender as Castiel relaxes.
"You're gonna be amazing for me today, Cas."
Cas smiles, blinking slowly and reaching out for a kiss. Dean obliges him, letting their lips meet. "Of course I am," Cas says confidently, wiggling his ass as best he can in the restraints.
Dean grins and stands up, running his hand through Castiel's hair and hearing his omega growl in pleasure in return.
The first step is simple; Dean reaches under Cas and strokes his cock using the resulting pre-come to help ease the way. Castiel gasps and arches into the restraints, head down and watching what Dean's doing.
Dean can already smell the honey scent of Cas' arousal and stops before Cas gets too far into his arousal. He pulls Cas' favourite toy - a vibrating prostate massager - out of the cupboard along with his own favourite toy - a long dildo with an inflatable knot at the end; he loves how much it teases Cas' internal slick gland.
Using Cas' own lubricant to guide the way, Dean slips the prostate massage in, relishing in the sound of the gasp that comes from Cas as it sits on the perfect spot.
"Want me to turn it on?" Dean teases, manoeuvring the toy with one finger, making Cas squirm and whine.
"Please, Dean, please!" Cas cries. "Don't leave me like this, Alpha."
Dean stops, then runs a finger down the length of Cas' spine. "Oh, sweetheart, I won't leave you until you've had at least two orgasms. Then I can leave you to it for the others."
Seven is the recommended number of orgasms for a healthy clear out. The doctor pulled ten out of Cas that first time before they never went back, a few too many, leaving him barely coherent. Dean tends to aim for seven, if they don't reach it, it's not the end of the world and he's usually able to achieve it the next morning after Cas has had a rest.
The first one comes quickly; Dean turns on the vibrator and Castiel lets out the perfect yelp as the vibrations nail his prostate. He lets the vibrator do the work, massaging the round globe of Castiel’s ass slowly. Castiel’s breath speeds up, huffing and heaving, muscles tightening up in ways they haven’t done in months. It’s the best sight to see.
Dean’s own cock is taking interest, but he palms it back down knowing he’ll have to wait for the evening to let himself sink into Cas’ ass.
Short sharp gasps of Dean’s name falls from Castiel’s mouth. “I’m—!” a growl comes from Cas as the first orgasm washes over him. Dean crouches down, rubbing his hand up and down Castiel’s back, soothing him through it. The sticky fluid lands on the soft blue leather.
“That’s perfect, omega. So perfect.” Dean removes the toy and lets Castiel rest for a moment, letting him have some water through a straw and a couple of bites from a granola bar. That was another luxury of doing this from home: no arm bruising IV hydration. “Ready for one more, then you can rest properly and I'll get you your cage.”
Castiel nods, so Dean picks up the second toy. It’s flesh coloured with a black hand pump for the knot. It’s Dean's favourite part, how he gets control over how big the knot is. After the prostate massager and Castiel being relaxed from his first orgasm, the dildo slides in easily in one go with a long groan from Castiel.
Dean showers Cas with whispered praise and he relaxes again, the honey and lavender mixing in a balm that soothes Dean’s alpha too. He starts slowly, rocking the dildo in and out no more than an inch. Only when Castiel’s cock starts to fill again, does he begin to make the strokes longer and longer, pushing the dildo in with more and more force until he has a good pace and keeps it up until Cas cries out with his second orgasm.
He praises Cas, then swipes up a finger of semen from the ottoman and directs it into Cas' mouth. "That taste good sunshine?”
Cas nods.
Unlocking the metal cage, Dean kneels and slips it over Castiel's cock and locks it into place. For the next orgasms, he might release small amounts of fluid, but he won't be hard.
It's going to take a while, so Dean gives him some more water, followed by the rest of the granola bar.
The prostate massager is slipped back into Cas' hole and a metal band slips over it, connecting to the restraint over his waist, to keep it in.
Dean holds the remote in his hand, presses several loving kisses to Cas and a reminder he can call for him if he needs him, and then leaves the room.
He sits on the couch with the recliner up and grabs his book from the side table, flipping it open to the page he'd left off from.
Dean clicks the first button the moment he begins to read. He hears Cas whine and groan but doesn't let the noises distract him. When he reaches the end of the chapter, he looks up to see Cas arching his back and a dribble of come land on the ottoman.
He watches as Cas gets his breath back, but doesn't let the vibrations let up. Chapter 6. He selects the vibration mode of random patterns — on, off, on, harsher, softer, harsher again then pausing and over and over again.
Dean resumes reading, it's just getting to the good part. He's read this book several times over, it's one of his favourites. Sometime during chapter six, Castiel's fourth orgasm runs dry. Dean stops the vibrations using the remote, giving Castiel a break.
Chapter 7. Having given Castiel a break for just under ten minutes, Dean switches the vibrator back on and catches Castiel squirming against the restraints. He hears him whispering but doesn't know what he's saying so he dog-ears the page and puts it to the side.
Going to crouch in front of Cas, he sees how wet his eyes are, how the blue has been replaced by omega gold and tear tracks run down his cheeks.
"Too much…" Cas says as Dean swipes a thumb over his lips. "It's too much."
"It's alright, just two more and we'll stop. Do the other one before bed or in the morning, how's that sound?"
Castiel hesitates. "Alright, I can do it."
"I know you can." Dean strokes through Cas' hair.
Dean returns to the couch, and flicks on the remote once again and returns to his book. The cries from his mate don't deter him from finishing the next chapter as two more orgasms are pulled from him. As soon as the sixth one is over, Dean slaps his book shut and returns to Castiel, turning off the massager and removing the belt keeping it in.
He undoes the restraints and helps Castiel, who's weak and unsteady on his feet, up. He brings him over to the couch, where he gets him laying across, with his head in Dean's lap.
Castiel sighs contentedly, nuzzling his head into Dean's stomach. "Mmm, this is nice.'
Castiel falls asleep within moments and Dean remains stuck under his mate. He doesn't mind since he can probably finish his book before Cas wakes up hungry.
There's something about having a naked mate on his lap after a milking session. It warms him from the inside, proof he can provide everything for Castiel that he needs to as a mate.
Later, once they've both had a decent meal and Castiel is feeling more relaxed as the day goes on, they head up to the bedroom and Dean sucks Cas off as he whines about his dick being too sensitive but Dean takes another dry orgasm from him regardless as Castiel cries and sobs over it.
Dean whispers praises to him, over and over and over until Castiel begins to believe it. The evening passes quickly and it's soon time for bed.
In three weeks it'll be Cas' heat and he'll have much more stamina for it and they'll both get to have a good time.
