Chapter Text
It didn’t happen overnight.
The abrupt increase of sweating should have been the first sign. But Spencer chalked that up to the weather. D.C was headed into May and as such. Summer was in full swing. The back pain perhaps should have been another warning. Spencer couldn’t sleep straight without a tiny flare of pain ripping through his lower body. Perhaps happiness clouded people’s judgement because Spencer had somehow missed all the initial signs of heat.
It wasn’t until much later when the young omega was tossing and turning restlessly on his bed did he realise the reason for his predicament. It struck Spencer when he found himself staring into the abyss, picturing himself kneeling between his alpha’s thighs. He dreamt about laying his soft cheeks against the unforgiving strength of the alpha’s iliotibial tract muscles. Spencer purred, just picturing the image in his mind. The sound of Jack letting out a loud laugh from downstairs broke the young man out of his reverie.
“Oh no”
Spencer dropped the cloth from his hand and abandoned the pile of laundry in favour of running out of his room. He managed to give Jack a shaky smile in the living room and made a beeline for Aaron’s office. He knocked the door in three quick successions and barely waited for his alpha give his assent before he pushed his way in, shut the door and leaned on it, panting heavily,
“I might be going into heat”.
Aaron’s head rose from the heap of files it was buried in. Aaron continued staring at his mate with a gaping mouth before his brain took over and he realized he was expected to answer.
Aaron rose from his seat behind his mahogany desk and moved towards the door. He brought Spencer into the room with a gentle tug on his forearm. With utter care, as though handling porcelain, Hotch pushed Spencer down by his shoulders to one of the chairs and took himself down to a knee before the omega. The alpha ran a soothing hand across the omega’s thigh, while the other took hold of Spencer’s dainty fingers.
“Are you sure?”
The younger man let out a shaky breath. “Yes, yes I am”.
“How far along do you think you are?”
Spencer rubbed his forehead. “I’m unsure. Three days, maybe? I just noticed the symptoms. I am really sorry, I should have caught them sooner. I don’t know wha-”
“Hey, honey? Breathe, breathe.” Aaron rubbed Spencer’s arm and waited for the man to catch his breath. “It’s okay, there are many reasons for you to be distracted. Don’t blame yourself. There is still time to make arrangements. I can call the heat centr-”
“The heat center?” Spencer paled. “I thought-”
“I didn’t think you’d want to-”
“But I want to-”
“Spend it with me”
“Spend it with you”
The two stared at each other. Spencer blushed and tucked his chin in the corner of his shoulder and looked away. Aaron smirked at his bashful behavior.
“Spencer, I don’t want to presume anything so-”
“No, Aaron. I want you there”, Spencer swallowed past the lump in his throat. He looked deep into the warm gaze of his alpha’s eyes. “I want to spend my heat with you.”
“Are-are you sure?”
Spencer brought a palm up to caress Aaron’s cheek fondly. He leaned down and pressed a gentle kiss to Aaron’s lips. Spencer pulled back from the kiss and rested his forehead against the alpha’s. “I am sure”.
Aaron smiled, leaning up for a longer, more passionate kiss. Things had been going really well between the two. The possibility of a heat was imminent, an afterthought for them both, but a part of Aaron wondered if he had earned enough trust and affection to be asked to spend the heat with his omega. Had Spencer chosen not to, Aaron would have respected his wishes, no matter how much it would have pained the alpha to do so.
But now Aaron’s heart soared with happiness knowing that Spencer trusted him enough to do this.
“How many days do you think you have?” Aaron asked, still kneeling in front of his mate. They were a hair’s distance away from each other, their lips moving in a whisper.
“Three days, by my calculation. We have enough time to make arrangements for Jack and both our jobs. This time should be slightly longer, about a week, considering that, you know, it is my first heat with my mate”, Spencer looked away bashfully, a blush colouring his cheeks.
“I will take care of Jack and my job. We will also need to do a supply run, won’t we? Some electrolyte drinks, energy bars, some of those dried cranberries you like. I can stop by the Indian restaurant on the way. Ask them to deliver different food each day on our doorstep. Establish some sort of online payment with them. Do you think we should get extra sheets? I could make a Target run? Maybe get some toiletries on the way too?”
Aaron rambled on and on and Spencer smiled at him affectionately. He had heard of the wonders of Alpha brains and how overprotective alphas got during their mate’s heat but witnessing it first hand made Spencer want to sob with happiness. Spencer had always looked after himself. Heat, on his own, was an inconvenient chore. Pre-heat care, after care, it was all left to Spencer. But now, to have someone else bear the brunt of his burdens, it was heartwarming.
Spencer cut off the alpha mid sentence by giving him a searing kiss. When they parted, Aaron looked up at his mate with glistening, earnest eyes.
The next few days seemed to pass in the blink of an eye. Spencer was busy making arrangements for his teaching responsibilities and for Jack. While Jess had no problems looking after her nephew, Jack had become very dependent on Spencer. He understood why his daddy and Spencer needed to be alone but he pouted at being separated from them for so long.
Aaron, meanwhile, went alpha-crazy. He bought a mini refrigerator that Morgan was planning to sell and filled it to the brim with energy drinks and Spencer’s favourite ice cream. He baked three whole trays of brownies and bought enough snacks to feed a village. The pair had decided to spend the heat in Spencer’s room, since it had the nest. Hotch had purchased a plush armchair for Spencer’s room along with about a dozen sheets and new beddings. Spencer had to often pull the plug on several of his mate’s outlandish proposals. Spencer even had to hide Hotch’s phone for a few hours to prevent the alpha from calling a real estate agent, because the alpha brain had deemed their house ‘unsuitable for providing optimal comfort for such a wonderful omega’ .
The pack had been ecstatic when Aaron had filed in his leave and dropped his files to Morgan, who would be the Acting Unit Chief in the interim. JJ and Prentiss had made several large servings of lasagna and casserole while Garcia had got Spencer plush, soft toys and the cuddliest blankets. Rossi had given them coupons for a spa massage for their post-heat days. Spencer knew the pre-heat hormones were to blame but he couldn’t help but get teary eyed at the affection shown to him by the pack.
When the day of the heat finally came, the arrangements were already put in place. Both their leaves were approved, Jack was already at Jess’s and everything was perfect.
Spencer had appeared near the kitchen doorway where Aaron was drying the last of their dishes from lunch. Spencer was about to drop on his knees but he managed to pitifully whine for his alpha.
“Alpha” Spencer groaned from the doorway and Aaron’s head turned to his mate, the brown of his eyes overtaken by the black as his rut kicked in. Aaron hastily pushed the plate away and went to Spencer, lifting the omega in bridal style as he ran up the stairs. Spencer spent the whole way whining and squirming, his nose pressed to the alpha’s scent gland.
Aaron deposited the omega in his nest and hovered over his mate, kissing every inch of Spencer’s face. Spencer leaned back from the kisses and turned over on his hands and knees, the urgency to present taking over his being. Aaron sat back on his haunches as Spencer quickly shed all his clothes and pushed his ass in the air, his face buried in a pillow underneath. His hole was dripping with slick, the insides of his thighs glistening in the warm light of the nest.
Aaron groaned at the back of his throat. The omega looked so good submitting like that. Aaron tore away his own clothes, throwing them behind him in haste. As soon as he was naked, he raised himself on his knees, situating himself behind Spencer.
The urgency of Spencer’s heat and Aaron’s rut meant that they were far too desperate to take the time to play with other’s bodies. Aaron lined himself up with Spencer’s hole and pushed in. Spencer buried his face deeper into the pillow, groaning as every inch of the alpha cock entered him. It felt like a lifetime before the Alpha’s balls hit his skin, signaling that every inch of that delicious cock was finally inside Spencer.
Aaron leaned back, taking in the beautiful sight of his cock pushed inside his mate. If he could, he would stay here forever. Holding Spencer by the waist, Hotch began moving in and out, his eyes fixed at the sight of his cock seeking entrance at the hole again and again. With every slap of their skin, Spencer’s ass became redder. Aaron raised a hand, lightly swatting one cheek. Spencer jerked forward with surprise but moaned at the rough display of affection.
Aaron could feel his knot growing. He caught Spencer’s forearm, bringing his mate closer to his chest. Spencer was gasping and moaning, beyond lost in lust. Aaron caught sight of the omega’s front and growled at the sight.
Spencer felt the alpha guide his hand to his stomach. The alpha slowed his pace a bit, his thrusts more forceful.
“Feel” alpha commanded.
Beneath the palm that the alpha held against his stomach, Spencer felt the alpha’s cock move inside him. Spencer felt the skin under his finger tent with each thrust. The sight, combined with the knowledge that the cock was so deep within him, pushed Spencer to the edge.
“Alpha, please. Harder, faster.”
Aaron obliged, pushing Spencer back to all fours as he held Spencer’s waist in a bruising grip, pistoning in and out of the omega’s hole. He spared a moment to grab the omega’s cock, which came quickly. Feeling the omega’s hole grip around his cock tightening, Aaron came too, coating Spencer’s insides with his cum.
Stars exploded behind their eyelids as both the men fell into the mattress. They didn’t know how long they would be locked together. Aaron tried maneuvering them to a position they would be least uncomfortable in. Aaron snuggled in, closing his eyes and smiling against the omega’s shoulder.
He was woken a bit later by a needy Spencer pushing back into him. They were still joined, although Aaron’s knot had deflated significantly. Spencer, however, was unwilling to let go. He pushed his ass back on the cock and clenched, making Aaron harden quickly. For a moment, Aaron let the omega desperately chase his pleasure. Spencer looked so wonton, so needy. His eyes were shut as the omega tried pushing himself back on the cock. But without the alpha’s cooperation, he couldn’t reach the pleasure he was chasing.
Aaron took over, pushing the omega onto his front. Aaron climbed over, raising himself on his arms as he brutally pushed into Spencer’s hole. Spencer pushed his asscheeks apart, letting the alpha claim him harshly. They came within minutes, Aaron pushing in another load into the omega’s womb.
They had sex thrice more. With each orgasm, Aaron added more cum to the preexisting load inside Spencer. By the end of it, Spencer had a little bulge. Spencer was skinny enough that the bulge on his stomach made him look like he was in his early stages of pregnancy. Spencer kept rubbing a hand over the bulge reverently, lost in omega subspace.
Aaron knew he should pull away, put some food and water in them both before another wave of heat overcame Spencer. Before he separated though, he pulled a sheet under Spencer’s ass, knowing that his cum would leak out in rivulets. When Aaron pulled his semi-hard cock out, Spencer’s ass pushed out all the excess semen. Aaron watched in fascination as the white cum leaked out, collecting on the disposable sheet underneath. Once everything was pushed out, Aaron threw the sheets away. Spencer snuggled back into the sheets.
Aaron chuckled at his mate went and to the en suite and filled the tub with warm water. He added some bath salt and proceeded to light a few candles around the small room. Then he collected his mate and deposited Spencer in the water. Spencer was barely awake but moaned in ecstasy as the warm water washed over his sore muscles. Aaron kissed Spencer’s forehead and the omega gave him a drunk smile.
For any alpha, taking care of an omega during their heat was just as pleasurable as the sex itself. It spoke to their primal sense, to be able to care for their mate when the mate was too blissed out and delirious to care for themselves.
Aaron sat beside Spencer on the edge of the bathtub, rubbing a soft cloth over his mate and cleaning Spencer while Spencer leaned back and hummed in pleasure. Once Aaron decided Spencer was clean enough, he lifted the omega up, drying his mate with soft towels. He sat Spencer down on a bench in the washroom and rubbed shea butter lotion on his mate. Aaron dressed Spencer in a pair of boxer shorts.
“Mmm. Alpha so good”, Spencer said, giving his mate a kiss in thanks.
Aaron blushed at the praise, lifting the omega and taking him to the nest. Aaron then took a short shower, dressed and went downstairs to get them some food from the fridge. He fed Spencer a good portion of casserole and made the omega drink some juice. As the well-fed and well-loved omega fell back in his embrace, Aaron had to physically restrain himself from spilling the words out.
***
Spencer smiled into the alpha’s shoulder.
They were resting on the armchair by the window, the alpha’s cock half hard and buried in Spencer. Spencer’s heat was in its last stage. The biological urgency of sex had lessened considerably but that didn’t prevent the mated couple from indulging in each other’s bodies. Things had irrevocably changed between them and only for the better.
They were cuddling in a sleepy embrace. The alpha’s head was leaning back on the armchair, his chest rising and falling with soft breaths. Spencer was atop the alpha, curled across his lap. The omega was lost in thought, his fingers gently scratching the sparse hair on the alpha’s forearms.
Spencer’s body was relaxed in a post-coital haze but his mind was running a mile a minute. He was pondering all matters of things. His work, for instance. The politics of establishing a department, fighting with the brass on employing talented professors, regardless of secondary sexuality. He was already earning the scorn of some higher-up alpha administrators. Spencer was indispensable for the university, at this point. Already, the STEM academia around the northern hemisphere was brimming with excitement about Spencer’s initiatives and his personal work. Everything he did, all that he published also brought attention to the university. No matter how angry the old white alphas were, they couldn’t fire Spencer. For perhaps the first time ever, Spencer knew his worth. Aaron had hooked him up with lawyers who cross checked all university contracts that came across his desk. Spencer, for the first time had leverage, had power. And oh, how novel it felt to know that he held all the cards, omega or not.
For another, there was the FBI. After providing free consultation on a few cases, Spencer had been contacted by the Assistant Director of the FBI himself. Spencer’s security clearance was raised to the same level as Aaron and he was being offered money for each hour of consultation. Spencer had discussed with Aaron on getting a degree in criminal and abnormal psychology. The alpha was supportive of it and the pair had spent a good amount of time hunched over college brochures. They had settled on University of California - Irvine and the university was more than happy to fund a PhD scholarship for Spencer.
His personal life, as evident by where he was right now, was definitely going just as well as his professional life. Spencer smiled and pressed a kiss to the pectoral where his cheek was resting. The alpha’s support was crucial in the recent developments in Spencer’s life.
“Your thoughts are too loud” the alpha sighed, squeezing an arm around the omega. “What is going on in that beautiful brain of yours?”
“Just pondering on how things have changed”, Spencer remarked, leaning back so that he could look the alpha in the eye. Aaron was looking at him with a soft look on his face, his dimples on display.
“And how have things changed?”
“Well, there’s work. Everything is going so well. I am finally being treated right based on my intelligence, not on my sexual identity. There’s Jack, who is doing so well at school, making more friends each and every day. And then there’s you.”
“Oh? What about me?” Aaron asked with a teasing smile on his face.
“You know… all this.”
Aaron leaned forward to place a soft kiss on his mate’s lips. “You have to be more specific, sweetheart”
Spencer’s pale cheeks reddened and he fidgeted his hands in his lap. “I know our… relationship did not start out in the most conventional way possible but I really like how we are now”
Aaron chuckled and nipped lightly at his mate’s mating mark. “I am completely to blame for that”, he said before looking at Spencer earnestly. “I was too lost to realise what a blessing you were. I was stupid, so stupid, for envying the relationship you had built with my pack, my son. I thought you were trying to usurp me. But really you were just trying to make the best out of an awful situation. And I resented you for it.” Aaron sighed. “It will take me years to repent for my sins. But I will, Spencer. I will endeavor to treat you well, so well. I don’t care how long it takes for my penance, I will work until every bad memory I have given you is replaced with a thousand good ones”.
“Oh Aaron, there is nothing to forgive” Spencer murmured through tears.
Because it was true. There was nothing to forgive. Not when tiny specs of love were already blooming in Spencer’s heart.
