Our Pretty Incubus

The untitled original of this story was posted on tumblr to celebrate my 100th follower; it has been a while considering I'm creeping up on 200 followers now. Since my brain wouldn't focus on beta'ing and my attempts to work on a new CM story, my Grimm fic, Spencer Meets the Morgan or anything else I tried were quickly rejected by my muse, I tried this one. I've cleaned it up and added some to it.

Warning: Spencer is 16 in this story BUT incubi are considered adults at 11 and the majority are bonded by 14 (at least according to me). Thus this really isn't underage and I'm not going to tag it as such. I also don't specify how small he is, I'll leave that to the reader's preference.

Pairing: Spencer/Derek/Aaron, Spencer/Aaron, Spencer/Derek

For months the agents at the BAU have been searching for the home base of an illegal incubi trafficking ring. The group has been kidnapping incubi and selling them to the highest bidder. The incubi are being forcibly bonded to their buyer or buyers. Six people have already been killed during the abductions and they only seem to be growing in violence. The bodies of three incubi have been found as well; in desperation to escape their sexual enslavement, each had committed suicide. For an incubus, there is nothing worse than being forced to bond; once bonded they are unable to deny their bonded and cannot break that bond themselves. Their only escape is suicide.

But the BAU's hard work finally paid off and they raided the building, putting a stop to the trafficking ring. With the assailants being carted off to jail, they start releasing the unfortunate incubi from their cages. There are incubi everywhere; many of them still children awaiting their sexual maturity, their purity making it worth keeping them until they mature. The pure are the most prized via the black market and fetch the highest price.

The team splits up and starts searching the other rooms while specialized caretakers check on each incubus.

In an isolated room, Aaron finds a single incubus. The nearly nude young male looks up and Aaron is shocked by the intelligence in the boy's pretty face. The boy has wavy chestnut hair that reaches his shoulders and appears to be freshly washed. "You are safe now." Hotch looks around questioningly, confused as to why this incubus is alone. All the other rooms were filled with incubi. The boy obviously reads the confusion on his face and states matter-of-factly, "I am pure." Aaron's eyes widen. The boy looks to be about sixteen, practically an old maid for an incubus. The majority of incubi are bonded by fourteen, since they are considered adults at eleven. Aaron has never heard of an incubus remaining a virgin for more than a year or two at most after their maturation, much less sixteen! This incubus is a rarity that the traffickers no doubt intended to exploit.

Hotch opens the cage, offering his hand to the boy. The second they touch, the boy's brown irises change to a vivid violet. "Oh my god!" Aaron exclaims in shock, knowing exactly what caused an incubus' eyes to change. He'd long ago resigned himself to being alone. This beautiful incubus is his.

"Mate," says the incubus as he wraps himself around Aaron like a clinging octopus.

"Aaron, my name is Aaron."

The incubus continues to rub himself against Hotch contentedly. He coos, "Aaaarrroonn. Aaron and Spencer." Aaron shudders as he scents the pheromones the incubus is releasing into the air. Within seconds he's hard, the intoxicating scent wrapping around him like a cloud of pure lust. Spencer sinks to his knees and rubs his face against Aaron's clothed hardness. Aaron doesn't resist when Spencer opens his fly and swallows him down to the root. "Fuck!" Spencer is very good with his mouth, which is likely how he has been fulfilling his sexual urges since his maturation. Embarrassingly fast, Aaron shoots his load into the incubus' mouth and Spencer swallows with relish.

The door opens suddenly and Morgan gasps at the sight of his boss' cock in an incubus' mouth. "What the hell, Hotch?! We're supposed to be rescuing them, not taking advantage of them!" Derek rushes over and pulls the incubus to his feet. He gapes in shock as the boy's eyes change from vivid violet to a swirl of deep blue and violet. "Mate!" Spencer sighs happily, tackling the surprised agent to the ground. Like a cat, Spencer squirms and rubs himself all over Derek. The pheromones wrap Derek in their lustful grip. Derek is too entrenched in a daze to move, not even noticing as his pants are opened. He snaps back into focus when the incubus swallows his cock whole, sucking and licking with enthusiasm. "Fucking hell!" Derek shouts as the incubus moans blissfully around his dick. In far too short a time, Morgan too cums down the throat of the willing incubus. Derek lies on his back limp, stunned to his core that a pretty male incubus has chosen him as a worthy mate. Incubi are highly valued in their culture and being chosen as a mate by an incubus is an extraordinary honor.

Spencer stands and strips off the little strip of cloth protecting his modesty. He turns toward Aaron, trapping the older man in his lustful gaze. The vampire is frozen, staring into the continually swirling eyes of the incubus. He feels like those eyes are hypnotizing him. Spencer slinks over to Aaron, carelessly stripping off Aaron's impeccable suit until he is completely bare. Pink lips meet Aaron's in a sweet, burning kiss, lighting a fire within the older agent. Aaron whips the incubus around, pushing him against the wall. Spencer arches, cooing as his mate manhandles him. Aaron's hands glide down Spencer's bare skin until they cup juicy cheeks. "Mate. Need you. Claim me, Aaron!" Spencer cries. Aaron growls and easily lifts the small incubus, who eagerly wraps his legs around him. Aaron brushes Spencer's silky hair aside and sinks his fangs into his pale neck, drinking his sweet, sweet blood while Aaron's finger wanders to his virgin hole. The pleasure of Aaron drinking from him is enough to send him flying over the edge and Spencer pulses wetly between them. Aaron's finger breaches Spencer's entrance to find him wet and ready for him. He regretfully pulls back, licking the bite mark to close it.

Just as Aaron is about to stretch Spencer, he hears Derek speak. "Turn around, Hotch. I'll get him ready for us." Obeying, Aaron pulls Spencer away from the wall. The incubus is light in his arms and makes no protests. Aaron watches as Derek sinks to his knees behind Spencer. Derek spreads his cheeks and breathes in the scent of the incubus' slick; it smells even more intoxicating to his enhanced senses. Incubi only produce lubrication for their mates. Spencer mewls into Aaron's neck at the feeling of his other mate's tongue on his hole, lapping up his natural lubricant. Derek adds a finger then two, stretching Spencer's muscles. Aaron distracts Spencer by devouring his sweet mouth. Spencer grumbles happily as his tongue carefully traces Aaron's sharp fangs before tangling tongues with Aaron. Derek works slowly until that little hole can swallow his whole fist. "He's ready," Derek states as he rids himself of his clothing. He can think of nothing but claiming his beautiful incubus.

Aaron meets Derek's gaze. Without words, they decide to take Spencer standing up. There is no bed and they're not going to take him on the floor. Derek grabs Aaron's cock and guides it inside of their pretty incubus. Within seconds, Derek is also inside that wet heat. "Yes! Mates! Fill me! I need you!" Spencer cries. Derek replies, "You've got me, got us. Baby. My pretty little incubus. My Pretty Boy." Spencer coos at the endearments. The werewolf thrusts forward as Aaron retreats and then pulls out as Aaron surges forward. Spencer's body clutches at their cocks, preventing them from slipping from his body. Again and again they thrust into Spencer's pliant body. The incubus is being driven mad with lust, a hunger like he's never felt before claws at his insides; it consumes him. He needs his mates' cum inside him. Spencer's body jolts with each thrust, both of his mates too far gone to restrain their supernatural strength. His mates filling him is the only thing that keeps him from crumbling under the aching hunger. Aaron cums first, sparking Spencer's release. The feeling of his mate's seed inside him is an ecstasy that Spencer has never felt before, the incubus in him is singing.

Fast approaching the edge, Derek bites his Pretty Boy's shoulder, growling "Mine!" Spencer cries out, his cock filling rapidly at being claimed by his other mate. Derek thrusts a few more times before he plunges deep and holds himself still as his knot expands and traps not only his cock inside but also Aaron's. Locked together, Derek pulses and fills his Pretty Boy with his cum. Spencer mewls softly as he cums again at the feeling of the knot locking the three of them together and of Derek's seemingly unending burst of hot seed filling him up and feeding his aching, soul-deep hunger. Aaron rocks his hips experimentally, he can't move much but Derek's knot and Spencer's fluttering muscles provide more than enough friction for him to get hard again and cums. Derek's cock releases one last spurt before finally finishing, hurling Spencer over the edge one last time.

Spencer is completely limp, his sexual hunger truly satiated for the first time since his maturation. He mumbles, "Mates, my mates," before slumping forward against Aaron and falling asleep. Both of them are pleased that their incubus trusts them to keep him safe as he slumbers.

It takes a few minutes before Aaron can pull out, the vampire helping to ease Spencer back into Derek's arms. Derek cradles the sleeping form tenderly, guiding his mate's head back to rest on his shoulder. The vampire goes over to the table, spotting a brand new plug, likely for when Spencer was given to his buyer. When the werewolf's knot shrinks and Derek is able to pull out, Aaron gently inserts the plug. It will keep their semen inside the incubus, which should sustain him until they can get him home. Derek looks immensely content with his incubus lovingly cradled in his arms.

"He's ours now," Derek announces, his tone slightly defiant as if he fears Aaron will disagree. He meets Aaron's intimidating gaze without flinching.

Aaron's eyes flick to Spencer, his expression softening as he takes in the sleeping incubus. He looks back up. "He is ours. No one can take him from us." Spencer had claimed them first and willingly mated with them. His swirling violet-blue irises are undeniable proof of his willingness. He is theirs. Aaron carefully pets Spencer's soft hair before trailing a slim finger over his claiming bite on Spencer's neck then tracing over Derek's claiming bite on his shoulder. "No one can deny our claim on Spencer."

"Spencer," Derek says as if tasting the name.

Aaron meets Derek's eyes again before he scans Derek's fit body. The werewolf is in excellent shape, powerful and strong. When Aaron's eyes finally come back up to meet Derek's, the werewolf's brow is raised in question. Aaron shrugs before explaining, "We are Spencer's mates, correct? That means we're all mates, not just me and him or you and him but me and you too."

Derek swallows thickly as Aaron leans in, his boss hesitating for a second a breath away from his lips. Derek closes the distance between their lips, the kiss chaste and almost shy. But then Aaron grabs Derek's face in his strong grip and kisses him for real. Derek's chest rumbles as his lips battle Aaron's even as Spencer sleeps in his arms between them. Aaron pulls back grinning, kissing Derek is definitely different than kissing Spencer but the chemistry is there. He is confident that this triad will work. He and Derek will no doubt fight for dominance as they both have dominant personalities as well as being powerful supernatural creatures but they will have Spencer to balance them.

Aaron quickly dresses, pulling on his wrinkled suit but leaves off his undershirt. "Give him to me and you can dress." Derek hesitates for a moment before handing over the still sleeping incubus. Aaron cradles him as gently as Derek had. Clearly Aaron and he are thinking along the same lines as Derek pulls on his clothes but deliberately leaves off his boxers. Working together, Aaron and Derek dress Spencer in Aaron's undershirt and Derek's boxers. Aaron hands Spencer back and they walk out.

Rossi is the first one they encounter. He doesn't say a word, simply quirking a brow in question at the incubus cradled protectively in Morgan's arms. Derek grins while Aaron shrugs and exposes their claiming marks on the incubus. "Why don't you both take him home? We can finish up here without you," Dave offers.

Aaron thinks it over. He knows there are plenty of others here to take care of all the captured incubi and he trusts Dave to act in his stead. Plus, Spencer will likely wake soon and need another feeding. Nodding, Aaron says gratefully, "Thank you, Dave. We appreciate it."

Aaron finds an incubi caretaker and asks her to check Spencer out quickly before they leave. The caretaker gives Spencer a clean bill of health and suggests they take him somewhere safe for his next feeding. Satisfied, Aaron and Derek take Spencer out to the SUV. They nod at JJ, Kate, and Emily as they leave.

"My place or yours?"

Derek sits in the back with Spencer. He answers, "Mine. I'm out in the woods."

Aaron makes an agreeable noise as he gets into the driver's seat. The quiet and isolation will be nice as the bond between the three of them solidifies.


Notes: This'll be a multi-chapter fic but don't ask me how many chapters because I have no idea. I seriously have no plans yet for what will happen next; if you have ideas, feel free to share!

The others will probably be some kind of supernatural creature too. Since I don't know how much they'll be in this story, I haven't decided what yet… JJ might be an elf…or maybe a fairy. I'm open to suggestions.
