Growth Spurt

"What's going on?" Jesse asked as he entered the med lab area of Sanctuary. He had been out at a Club with Emma. Not a date or anything, just two friends chilling out and listening to some good music. But Shalimar had called them back, stating that it was an emergency.

Adam answered the question. "It's Brennan," he stated, pointing to the dark-haired man lying on the bio bed.

Emma was concerned. "Is he all right? What happened?"

"Near as I can tell, Brennan is going through another growth spurt," Adam replied.

"And that's an emergency...why?" Jesse prompted, confusion in his tone. They had all been going through growth spurts in the past year. Fluctuations and increases in their abilities. Sometimes it got a bit scary or dangerous, but to date Adam hadn't considered it something to freak out about. Not that Adam ever really freaked out about anything, but Jesse noted that Shalimar was looking a bit tense.

Adam opened his mouth to explain when Brennan's eye popped open and the big guy jumped off the bio bed. "You need to rest," Adam told him, and was promptly ignored.

Smiling at Emma and Jesse, Brennan moving around the room, half dancing half pacing. "Not tired," he stated. "Itchy."

"Has he been watching Buffy again?" Jesse teased, listening to Brennan's condensed verbal skills.

"No Buffy," Adam said, heaving an exasperated sigh. "Guys, this is going to sound insane...but it's very serious."

Emma was beginning to feel Adam's frustration, along with his concern. "What's going on?' he demanded.

Shalimar decided to take a crack at trying to explain it. "This particular growth spurt seems to have affected Brennan...sexually."

"Meaning what?" Jesse asked, even though he wasn't quite sure he wanted to know the answer. But before anyone could reply, Jesse found Brennan standing before him . Sniffing him. "Back off!" Jesse hissed, pushing Brennan away. The big guy stumbled back a few steps only to regain his balance and move right back in again. Jesse resisted the urge to slap him. "Is Brennan changing into a dog?" he asked plaintively, looking to Adam for help.

"Brennan needs to mate," Adam explained. "If he doesn't...he could die."

Emma was more than a little bit stunned by that statement. "Die?" she echoed. "How? Why?"

Adam shrugged. "Near as I can tell from the scans and tests I've been running, Brennan is a mass of surging electricity. The only way to neutralize it to a safe level is for him to bond to someone who is...compatible, as it were. If he doesn't do that and soon, he will fry himself from the inside out. Literally."

"That's gross," Jesse said, making a face as he backed away from Brennan. Kept going since Brennan was keeping pace, but stopped when his back hit a wall. "Get him off me," Jesse requested. "What is with the sniffing?"

"He likes your scent," Adam said. "For some reason Brennan seems to be reverting to cave man mentality. Simple...basic...instinct. Primal instinct."

Jesse rolled his eyes then pointed to Shalimar. "Go sniff her," he ordered Brennan, and was promptly ignored. "Isn't he supposed to be sniffing at the girls?" Jesse stated, pointedly.

Adam grimaced and spread his hands in a gesture of helplessness. "Gender isn't an issue, Jesse. It's all about comptability. And right now we need to do whatever it takes to calm Brennan down, which will slow down the rate of the electrical flow, at least until Brennan finds and, or, chooses his mate."

"Great," Jesse drawled. "Go sniff Emma!" he hissed at Brennan, only to yelp as a wet tongue licked his neck. "Hey! Cut that out!" Jesse snapped. He tried to push Brennan away again but found his wrists gripped in strong fingers and then he was upside down, having been slung over Brennan's shoulder. "Adam!" Jesse shouted. "Do something!"

"There's nothing I can do, Jesse," Adam replied, although he and the others did follow Brennan, who was heading out the door. "I don't want Brennan getting upset or angry. It will speed things up and we could lose him in a heartbeat."

Jesse pounded on Brennan's back in frustration and wanted to scream when he heard the big guy chuckle. "This is a joke. Isn't it?" he threw out, hopefully. Jesse waited but no one started laughing. Then he yelped again as he was dropped down onto Brennan's bed. He hadn't even realized where they were going. Scrabbling away in an attempt to roll off the bed and escape, Jesse found his way blocked, then he found a big body wrapped around him, and long fingers combing through his hair. The creepiest thing was the fact that Brennan seemed to be purring in contentment. "I want out of here!" Jesse hissed. He struggled to get away but Brennan was too strong. Jesse was just about to phase out when he felt a hand on his arm. A different touch.

Adam squeezed Jesse's forearm and shook his head. "Don't," he pleaded. "Just go with the flow, Jesse. I think Brennan just wants to cuddle with you. It's calming him and that's what we want right now."

"You can do this, Jess," Shalimar interjected, knowing how important this was. "For Brennan's sake. Just let him hold you. No big deal."

"No big deal," Jesse echoed, then he heaved a sigh of resignation. "Fine, he can cuddle. But that's it. Got it?" The latter was directed at Brennan who simply smiled at Jesse.

Adam watched, a half smile on his face, as Brennan wrapped himself more completely around Jesse's slighter form. He knew that Jesse was extremely uncomfortable with this and Adam didn't blame him. But, for whatever reason, cuddling with Jesse seemed to make Brennan happy and Adam didn't need to scan the big guy to know that the surging inside him was easing up. "Try to get some sleep, Jesse," Adam advised the young man. "It's gonna be a long haul."

Jesse heaved a sigh then swallowed a yelp as one of Brennan's hand cupped over his crotch. Jesse grabbed it and moved it only for it to find it's way back. He tried to move it again only to find his wrist grabbed and held in a grip that was almost painful. "How long is this going to last?" Jesse asked Adam.

"I'm not sure," Adam replied, with complete honesty. Although he knew that Brennan's time was limited.

"So when is Brennan going to pick his mate?" Jesse continued. "And can't we help him with that some how? Like...now?" Tugging at his wrist, Jesse tried to free his hand. No luck. He grimaced then gave up, jumping a bit as a long arm curled around his waist to draw him even closer back against Brennan's chest. Jesse bit back a yelp as he felt something hard pressing against his ass. Knew what it was. Brennan's erection. "I can't do this," Jesse whined, looking at Adam with hopefilled eyes. Couldn't say what was wrong and to even try would pretty much kill him with embarrassment, especially since Shalimar and Emma were hovering nearby. But Jesse wasn't sure he could do this.

Adam moved to kneel beside the bed and spoke softly. "Jess..I know this isn't easy, but you need to do this to keep Brennan alive. If I could do anything to change this...you know I would. You just have to deal. Okay?"

Jesse jumped when he felt a warm tongue licking the nape of his neck. Just what he needed, Brennan slobbering on him. "Okay," he said, knowing that there was no other choice, and Jesse didn't want Brennan to die. "Just tell me one thing, Adam. Is Brennan going to remember this once he's mated and he's all better?"

"I don't know, Adam replied. "Probably. Why?"

"Great," Jesse groaned. "Just what I wanted to hear."

Adam smiled and patted Jesse on the arm. "Sleep," he ordered, then he rose to his feet and headed off, taking the girls with him. "I'll check on you later," Adam called over his shoulder, then they were gone.

Jesse sighed again as Brennan licked him again. Tugged at his wrist and there was no give. "Unbelievable," he whispered, then he shifted a bit to get more comfortable or rather as comfortable as he could get with Brennan wrapped around him like a blanket. Then Jesse closed his eyes and let his mind drift. Surprisingly enough, he fell asleep.

*****

Jesse woke up slowly and to the odd sensation of being...alone. He opened his eyes and was relieved to discover that he was by himself in Brennan's bed. Rolling off and onto his feet, Jesse headed for the door. The hallway was empty so he headed for his room and made his way into the shower. Washed up and dressed in jeans and a sleeveless sweater before running his fingers through his hair. He was starving so next stop was the kitchen.

Once there Jesse realized that it was eerily quiet in Sanctuary. He grabbed a donut and went out to the nearest control panel where he punched a button. Was about to make a request when he sensed a presence and turned to see Brennan smiling at him.

"We're alone," Brennan said softly. "They went out."

"Out...where?" Jesse asked, suspicion coloring his tone.

Brennan moved closer. "Mission," he replied.

Jesse winced. Being alone with Brennan was the last thing he wanted right now. "Um...so, Brennan...you feeling okay?" Jesse asked, feeling him out.

"Fine," Brennan purred, moving into Jesse's personal space. Then he leaned in and...sniffed.

"Stop doing that!" Jesse shouted, pushing Brennan away. "Shouldn't you be out finding your mate instead of sniffing me?"

Brennan stalked Jesse until the younger man was pressed against the wall. "I found him," he said, deliberately.

Jesse got the meaning all to clearly. "Him?" he echoed, then he shook his head. "No..not me. It can't be me. You like girls, Brennan. Women. Get it?"

"Like women," Brennan allowed. "Want you." He leaned in hard, pressing himself full length against Jesse, and when he felt him take a deep breath in preparation to phase away from him, Brennan charged up his index finger and zapped Jesse, catching him when the younger man's knees buckled. He had zapped a little too much power and Jesse was out for the count, but not for long. Brennan felt him stirring so he reached in his pocket for the innoculator he had taken from medlab and pressed it to Jesse's throat. No more worries about phasing or massing. Jesse was his. Smiling, Brennan tossed the innoculator aside and gathered Jesse up in his arms, heading for his room.

"Shit.." Jesse moaned, wincing at the after shock of pain that rippled through him. When it faded he opened his eyes and jumped. Brennan was looming over him. "Why did you do that?" Jesse snapped.

Brennan's reply was to kiss him. He stopped only when Jesse bit his lip. It didn't hurt so much as excite him. "Mine," he whispered, licking a stripe from Jesse's ear to his cheek. He liked the taste of Jesse. Clean and pure.

Jesse had had enough. He took a deep breath preparing to exhale to phase out then realized his powers were gone. "What did you do?" he demanded.

"Neutralized you...for a while. You're fine," Brennan replied. "Beautiful." He watched Jesse blush and laughed.

"This isn't happening, Brennan," Jesse stated firmly.

Brennan licked Jesse's mouth, the tip of his tongue playing with the beauty mark on the upper lip. "Has to happen. Mine now. Need you."

Jesse opened his mouth to protest but was silenced by the tongue Brennan shoved in his mouth. Tongue. Jesse was stunned by the realization that Brennan was french kissing him. Kissing...with tongue. He froze until he felt hands under his shirt and finger tweaking his nipples. "No!" Jesse gasped, breaking the kiss. He tried to push Brennan off him but strong hands grabbed his wrists, both in one hand, and pinned Jesse's arms over his head. Whatever was happening to Brennan was making him physically stronger as well. And that made Jesse realize something else. Brennan felt warm, too warm. Fever hot. Jesse feared Brennan's condition was escalating. "Adam!" Jesse shouted, hoping that he would be heard.

"Yes, Jesse." Adam had been monitoring Sanctuary.

"I think Brennan found his mate," he shouted, then he moaned as a wet tongue licked his belly button. "He wants to mate with me, Adam!" Jesse heard the fear and desperation in his voice.

Adam was quiet a moment then said, "I figured as much."

Jesse hissed in frustration then yelped as a hand slid inside his unzipped jeans and curled around his cock. Didn't remember his jeans being unzipped. "Brennan...stop it!" Jesse snapped. For all the good it did. He was ignored, but ignoring the hand stroking his cock was impossible. He felt it harden. "Adam..I don't want to do this," Jesse stated. "I can't."

"Brennan will die if you don't," Adam said softly. "But it's your choice, Jesse. Do what you have to do." That said, Adam closed the link.

"Fuck!" Jesse hissed, then he tried to shift his hips to make Brennan let go of him. "Brennan...please...can't you find someone else to mate with?" he pleaded.

Brennan nuzzled his face against Jesse's cock, which he had now freed from the constricting jeans and briefs. "Need you," he said succinctly, then he took the hard cock into his mouth.

Jesse yelped then moaned then tugged his wrists free while Brennan was distracted. As good as the lips going down on him felt, he wasn't ready to deal with having sex with another man. Especially when that other man was Brennan. Jesse tried to sit up and push Brennan off him, he might as well try to push a wall off him. Brennan was acting like a bulldog with a bone and he was very good at what he was doing, good enough that Jesse felt the tingle of heat in his spine that signalled his eminate explosion. "Brennan...please.." he begged, and wasn't sure what he was begging for at this point. Felt fingers squeezing his balls then it happened, a flare of pleasure setting off mini explosions in all his nerve endings, then Jesse was coming hard and fast.

"So good," Brennan whispered, after swallowing as much as he could then licking the rest off Jesse. "Need you, Jess. Inside you."

"No!" Jesse hissed, scrambling back on the bed. Not easy to do when his muscles felt liquified. "Brennan...I can't do this," he protested. Jesse was getting past the squick factor of it a bit, seeing as how he had just been given the most mind boggling blow job of all time, but letting Brennan fuck him was a whole nother matter.

Brennan wasn't about to take *No* for an answer. His thoughts weren't clear beyond having to mate with Jesse. Nothing mattered other than being inside him, a part of him, marking Jesse as his own. But one part of his mind still functioned on the level of reasoning things out. And Brennan had prepared ahead. He used his greater mass and weight to pin Jesse down to the bed, then he restrained each wrist in the padded cuffs he had bought at a sex shop a few weeks ago. Two sets of cuffs, one end of each was already attached to the head board.

Jesse struggled as Brennan restrained him, cursing his loss of powers, cursing Brennan's extraordinary strength in this moment. Then he was bound and Jesse stopped struggling. He wouldn't be able to free himself by physical means, so he would have to try and reason with Brennan. "I want to help you, Brennan," Jesse said softly. "I do. I can help you do...other...things. I mean...um...I could...stroke you off," Said it in a rush of embarrassment and closed his eyes wish he could melt away.

"Have to mate...make you mine...mark you," Brennan almost singsonged as he worked to remove Jesse's clothing. Boots and socks were easy to remove, so were the jeans and briefs, inspite of Jesse's struggles against him. The white shirt Brennan simply ripped over, leaving the tatters in place. Then Jesse was bare to his gaze and Brennan leaned in to sniff him.

"Why me?" Jesse pleading, willing himself not to blush again as Brennan sniffed and licked at him. Then the other man was pulling back and simply looking at Jesse with lust and need in his dark eyes. Jesse had never felt more naked or vulnerable in his life. Too naked. Too vulnerable. Too exposed. And far too helpless, which was what bothered him the most.

Brennan smiled then leaned in for a kiss. A part of him was wild with need and desire and simply wanted to spread Jesse's thighs and bury himself balls deep in the sweet ass. But a voice in his head whispered for him to be gentle and go slow. That Jesse would be his without force. And, for the moment, he listened to the voice. "Always mine," Brennan whispered, then he licked a stripe from Jesse's chin straight down to the tip of his cock.

Jesse shuddered as pleasure washed over him. He couldn't believe how his body was betraying him. Never in his 23 years had he ever even thought about having sex with another man, but suddenly his body was more than willing. "Yours?" Jesse countered, shaking his head. "I'm not your's, Brennan," he stated, tugging at his bonds. They held secure and Jesse cursed. "Brennan...I want you to be okay, but this is asking too much of me."

"Mine.." Brennan repeated, the voice in his head fading away to be replaced by a pounding of lust that couldn't be ignored. Slipping off the bed, Brennan shed his clothes then moved back between Jesse's thighs. He grabbed a pillow and slid it under the small of Jesse's back to make this easier for himself, then Brennan stretched out on his belly before pushing Jesse's thighs back so that the entrance of his body was revealed to Brennan. Smiling in satisfaction, Brennan leaned in and licked the puckered hole, lapping at it with his tongue, then penetrating deeply.

"FUCK!" Jesse screamed, his body jerking, then he was twisting his hips and kicking out in an attempt to escape the probing tongue. But Brennan's fingers bit into his thighs, holding him still, and the tongue kept probing and licking, slicking him. Jesse's cries of protest turned into moans as his cock hardened and ached against hi belly. "Brennan...Brennan...please!" Jesse whispered, brokenly.

Brennan would not be denied this. He was so close to getting what he needed. His tongue pushed in deep, stabbing again and again into Jesse, and he felt the taut body beneath trembling against him. Then he pulled away and pressed a long finger into the opening, pushing deep and twisting it until he felt Jesse stiffen and cry out. Another finger was added and Brennan scissored them, stretching Jesse, not wanting to hurt him but needing to be inside. Now. Pulled the fingers out then Brennan was kneeling between Jesse's legs, used his own spit to lubricate his cock as best he could, then he was pushing inside, pressing hard, thrusting hips forward, gaining entrance and feeling the slight burn of friction. Knew that he was hurting Jesse, although the younger man no longer cried out in protest, he simply whimpered and panted, body jerking a bit in a feeble attempt to escape. A part of Brennan felt regret at the pain he caused, but there was a pain inside of him, twisting in his cut and spiraling out to every nerve ending. Pain that was dark and red and he needed to find relief. And this was the only way. Another inch inside of Jesse and Brennan could feel the pain and darkness easing, fading gently away.

It hurt. That was all Jesse could think of in this moment. He sensed no malice in Brennan, even as the other man forced his way into Jesse's body. Brennan's cock was thick and hot and throbbing, filling Jesse too full, too deep. His fingers clenched into fists and he held his breath, trying to find a way to ease the pain, but there was no relief. Jesse closed his eyes against hot tears of pain and then it happened. Brennan stopped moving and went completely still. The pain was still there but it eased in intensity until it became more a matter of discomfort than true pain. Jesse realized that Brennan was all the way inside him and was giving him a chance to adjust. Opened his mouth to say something, although he wasn't sure if he wanted to thank Brennan or curse at him, when soft lips covered his and Jesse knew that the kiss was an apology of sorts. He accepted the distraction and wasn't aware that Brennan had moved again until he felt a sudden burn as the cock inside him pulled out to the tip. There was a moment of relief then the thickness was sliding back in, filling him. Pain again but bearable this time, and easing with each successive thrust.

"Mine..mine!" Brennan snarled, as he felt Jesse's tightness ease. A perfect fit now and he could move easily. This was how it was meant to be between them. How it would always be. Then Brennan felt the need take over and he gripped Jesse's hips and changed the angle of his thrust. Knew he hit the hot spot when Jesse gasped then began to moan. Brennan thrust in harder...faster....deeper, until there was nothing but this moment and this motion. Then it happened. The pain inside him exploded as he did, and Brennan felt his seed filling Jesse, marking him, making him his in a way no other person would ever be. As Brennan collapsed over Jesse, darkness claimed him, and he knew that it would heal him as well so Brennan allowed himself to sleep.

"Brennan?" Jesse tried to shift his weight but Brennan was too heavy. He realized that Brennan was either unconscious or asleep, either way Jesse wasn't too happy about it. Brennan was soft now, but still inside him and Jesse wanted him out. But that wasn't happening until Brennan moved, and Jesse knew he wasn't going anywhere at the moment. The only good thing Jesse could find about this moment was that Brennan had been kind enough to stroke him off to orgasm before collapsing. Only now he was a sticky, sweaty mess. Sighing in resignation, Jesse closed his own eyes and willed himself to sleep. But he sent a silent plea that Brennan would wake up before the others came home.

*****

Jesse came awake to the sensation of pleasure. Warm lips on his cock and he came in a rush, a moan escaping his lips. Decided it was just a dream and kept his eyes closed, hoping to slip back into deep slumber, when he felt hands on his thighs, spreading them, then a hardness was pressing into him. Jesse's eyes flew open and he stared at Brennan's smiling face. "Hey!" Jesse hissed, then moaned as he was filled again, Brennan not stopping till he was all the way in.

"Thank you, Jesse," Brennan said, his eyes locked on the younger man's face. "You saved my life." The sentiment was as sincere as his intent to give Jesse nothing but pleasure in their joining this time.

"You're...better?" Jesse asked, then he bit his lip as Brennan's cock brushed over his prostate and pleasure rippled through him.

Brennan nodded then bent to kiss Jesse gently. "Much better," he as he continued thrusting. Long, deep, strokes meant to pleasure Jesse even more than himself. But his own release was perilously close. When it came Brennan cried out Jesse's name. They were connected now in a way that Brennan couldn't even give meaning too. But he knew that Jesse would try to do that. Try and, no doubt, fail. Easing up from his slump over Jesse's body, Brennan kissed the younger man again then rose from the bed. He had untied Jesse upon awakeing and it almost made Brennan smile to see Jesse realize that he had been unrestrained this time. "Do you want to talk about it?" Brennan asked as he watched Jesse slide off the bed.

Jesse shook his head as he wrapped a blanket around him. "I want to shower," he stated, feeling an ache inside him and feeling Brennan's wetness dripping down his leg. It nearly drove Jesse to hysterical laughter, but he held it in. "Are the others back yet?"

"Not yet," Brennan replied, nothing more. He would let Jesse take the lead between them in whatever happened next.

"Good," Jesse said, then he headed for the door. Would have run to his room if he hadn't been so entangled in the blanket. And once there he dropped the blanket then headed into the shower. He stood beneath the hot spray for a long moment, feeling his body shudder in reaction to all that had happened. Then Jesse reached for the soap and scrubbed at his skin, but he couldn't erase the feel of Brennan's touch, inside and out. Still trembling, Jesse stood beneath the spray until the water ran cold.

*****

"Is Brennan okay?" Jesse asked as Adam approached him at the console. Knew that Adam had been testing Brennan since their return. No one had said anything to Jesse yet, simply leaving him alone at the computer. Jesse was grateful for that. But he knew that Adam would want to talk now.

Adam nodded. "Brennan is fine. Thanks to you." He noticed how Jesse couldn't meet his eyes. "I know it wasn't easy....what you did. Brennan told me everything. How he drugged you and restrained you. He didn't give you a choice in the matter, Jesse --"

Jesse shook his head and raised a hand to cut Adam off. "Brennan didn't hurt me," he stated firmly.

"Yes...he did," Adam countered softly. Firmly. He wasn't going to let Jesse pretend that nothing had happened. That everything was okay. They both knew it wasn't. "Technically...Brennan raped you."

"IT wasn't like that, Adam," Jesse shot back. "There was pain but there was...pleasure...too. He didn't mean to hurt me." A bit of a shock that, but Jesse had never doubted the truth of it. Then..or now.

Adam reached out and laid a gentle hand on Jesse's shoulder. Felt the young man start at his touch, but he didn't pull away. That was a good sign. "I think you need to talk about this, Jesse. I'm no psychologist, but I have a friend who could help you deal with this. She works with New Mutants..."

Jesse pulled away from ADam's touch and slid out of the console seat. "I do need to talk," he agreed. "To Brennan. We have to be able to work as team mates so I have to deal with how I feel about him after...after everything."

"Fair enough," Adam replied, and he was pleased with the way Jesse was handling this. He watched the young man walk away and felt a sense of fatherly pride.

*****

"Who is it?" Brennan called out, when a knock sounded on his door.

"Jesse."

That surprised him. "Come in," Brennan invited. He moved to the door way and was more than a little suprised when, the moment Jesse entered, he grabbed Brennan by the face and kissed him. "Um...what...what was that for?" Brennan asked, feeling a bit dizzy. Jesse knew how to kiss when he wanted to.

Jesse shook his head. "I'm not sure," he admitted. "What happened fucked with me in alot of ways, Brennan. One of them being that you marked me as your own and I think you meant it."

"I did," Brennan agreed. "No matter what happens between us from this moment on, Jesse....you will always be mine. I can't change that. When I got sick it was all about instinct. Survival instinct. And I never hesitated, but went straight for you. I knew you were the one who could save me."

"But we're not really even friends, Brennan," Jesse protested.

Brennan shrugged. "We can work on that," he said softly. "So..what happens now?"

Jesse chuckled. "Let's just say I'm feeling the need to mark my own territory," he growled, then he jumped on Brennan, sending them both down onto the bed. And it was a long time before either one of them left it.

THE END
