Chapter Text
“You’ve gained some weight, baby,” Derek Morgan said as he lay on his back, completely naked, on the bed with his arms behind his head. He was watching his lover, Spencer Reid, get undressed and when Spencer pulled his shirt off, Derek had noticed that his usually concave stomach was now sticking out slightly, threatening to hang over the waistband of his pants.
Spencer Reid, who had been in the process of unbuckling his belt and taking it off, suddenly stopped his movements and stared at Derek on the bed. His jaw fell open slightly and his brows wrinkled as he tried to process what his lover had just said. Spencer then blinked his eyes a few times and cleared his throat. “Has anyone ever told you how charming you are?” he said, his words dripping with sarcasm. He then turned around walked into the large bathroom connected to the master bedroom and shut the door.
“Spencer, where are you going?” Derek yelled after him, completely shocked at his lover’s reaction. On second thought, however, Derek realized that his statement could have sounded somewhat like an insult. He groaned and got off the bed, knowing that Spencer was a very self-conscious person, and berated himself for his momentary lapse in judgment. “Baby?” he said softly, leaning against the bathroom door. He tried to turn the knob when there was no answer, but found it was locked. “Baby, come on. I’m sorry. I didn’t mean it like that. Please, come out, baby boy.” When there was still no answer, Derek decided to change tactics, knowing his next words would probably put him in the doghouse for a while but at least it would get Spencer to open the door and talk to him. “Baby, you know when you take your clothes off, I’m only ever thinking of one thing… and that’s a little bit further south than your stomach!”
Just as Derek had predicted, the bathroom door suddenly flew open and Spencer stood there with an incredulous look on his face, as if he couldn’t believe that Derek had just said that. “I am not a sex object, Derek Morgan!” he practically shouted at the dark, well-built man who was almost four inches taller than he was.
However, when he saw the mischievous grin on Derek’s face, he sighed, realizing that Derek had only said that so that Spencer would open the door. “No you aren’t, baby boy,” Derek said affectionately, his grin growing wider. “You’re more like a sex god!”
Spencer chuckled at Derek’s playful complement and looked down and away from Derek as a blush creeped up his neck and to his cheeks. Looking down gave Spencer a full view of his slightly protruding belly, though. He put his hand on it and said quietly, “I guess I have gained a few pounds. You know, I didn’t even notice it until you said something.” He then turned around and brought out a bathroom scale from under the sink. He stepped on it and waited until it read correctly, then gasped at what it said. He backed away from it with a horrified look on his face and almost fell into the bathtub. “Oh my god, I’ve gained fifteen and a half pounds! The last time I was weighed was at my routine physical six months ago and then, I weighed 126 pounds, which means that I was technically underweight, but I haven’t gained a pound in nine years! Not since I turned 18! And now, suddenly, I weigh 141.5 pounds only six months later? I mean, that puts me at normal weight, but something has to be wrong! Maybe I should see a doctor –”
“Spencer, Spencer,” Derek interrupted, rushing over to his distressed lover and pulled him into a tight hug. “Calm down, baby, you’re ok. There’s nothing wrong with you.”
“I’ve just been really hungry lately and I’ve never had to worry about what or how much I eat because I don’t gain weight –”
“Spencer,” Derek said softly, interrupting him one more time. He drew back somewhat and gently grabbed the younger man’s chin so that Spencer had to look up at him. “It’s ok. This is what happens when people get older, baby boy.” Derek chuckled slightly and bent his head to kiss his lover lightly on the lips. Even though Spencer was only around four inches shorter than Derek, he couldn’t help but notice that Spencer always seemed to shrink within himself when he was upset in any way. Derek always found Spencer’s petite form to be endearing but he never enjoyed when Spencer felt like he needed to make himself smaller to disappear from the situation. Derek chuckled a little and, trying to make Spencer feel better, said, “I wouldn’t care if you weighed 300 pounds, baby boy. I just want you to be happy.”
Spencer’s eyes widened and he whispered, “I don’t want to weigh 300 pounds.”
At that, Derek laughed out loud and gave Spencer another big hug. “Oh god, I love you so much, pretty boy.”
Spencer chuckled nervously but hugged Derek back and softly said, “I love you too.” After a moment, however, Spencer pulled back and looked up at Derek, worry etched on his face. “Do you want me to go on a diet?”
“Not unless you want to do it for yourself, baby boy,” Derek said seriously but affectionately. “No matter what you look like, you’ll always be my pretty boy.”
“You don’t think I’m fat and disgusting?”
“No,” Derek answered immediately, shocked that Spencer would even suggest the notion. “Not at all, baby… and I never will either.”
“Okay,” Spencer said, still sounding uncertain. He looked down away from Derek’s face, and crossed his arms over chest.
Derek, seeing that Spencer didn’t really believe him, leaned down and kissed him savagely, his tongue forcing its way into Spencer’s mouth.
Spencer closed his eyes and moaned, leaning more into Derek’s body as he curled his tongue around Derek’s. As the kiss went on, Spencer slowly uncurled his arms around himself and put them around Derek’s waist, his hands reaching down to cup his naked butt cheeks.
Derek eventually pulled away, leaving Spencer almost gasping for air. He opened his eyes and looked at Derek, who was smiling. Derek leaned down to Spencer’s ear and, in a low, breathy voice, said, “Let me show you just how beautiful you are.”
Spencer let out a soft moan in anticipation as he bit his lower lip. He slowly nodded his head and brought his hands down to his pants to take them off.
Derek’s hands joined his and he whispered, “Let me do that.”
Spencer dropped his hands and let Derek unbutton and unzip his pants. Derek then shoved Spencer’s pants and boxer briefs down off his hips, releasing Spencer’s growing erection. The clothes hit the bathroom floor with a soft thud, then Derek grabbed Spencer’s hand and pulled him from the bathroom back into the bedroom. Derek then gently shoved Spencer onto the bed and spread his legs. Derek knelt in between Spencer’s legs and leaned down to attack his mouth.
Spencer reached his hands up and put one on the back of Derek’s head and the other on Derek’s shoulder.
Derek used one hand to prop himself up and let his other hand wander. He first combed through Spencer’s long hair, then slowly slid his hand down Spencer’s neck to his chest. He then brought his palm down to Spencer’s newly bulging abdomen, which Derek personally thought was kinda cute. He was slightly surprised when he discovered that the little protrusion was firm rather than squishy, but just filed that away to possibly bring up later when his mind wasn’t preoccupied with sex.
As Derek’s hand wandered lower, Spencer let out a moan of pleasure and anticipation, which made Derek smile and move his lips from Spencer’s mouth down to his neck. “Oh, Derek,” Spencer moaned as soon as his mouth was free to talk. His eyes were closed and he was slowly moving his head back and forth on the pillow. His breathing became more labored as he felt Derek grip his manhood and begin the stroke painfully slow.
Derek continued to kiss, lick, and suck at Spencer’s neck and collarbone as he breathlessly asked, “What do you want, baby boy? Tell me what you want.”
Spencer started to pant as Derek’s thumb caressed the slit at the end of his shaft, spreading the pre-ejaculate around the head. “I… I wa-want…” Spencer stuttered, trying to talk through his heavy breathing.
Derek chuckled lightly and looked up at Spencer’s face, not surprised to see his eyes closed and his mouth open as he made little keening noises, easily getting off just on Derek’s light touches. “Come on, baby,” he said as he angled his head then licked down Spencer’s side all the way to his hip. “Tell me what you want.”
Spencer made a noise of frustration as he tried think of the words to say, but everything except for pleasure was quickly leaving his consciousness. “I wa… want… mmmmm… y-you,” he finally struggled out before he felt Derek swiftly engulf his shaft in his mouth. Spencer let out a loud moan, closer to a scream than anything, as Derek bobbed his head, slowly taking even more of Spencer’s member into his mouth.
The first time Derek had seen Spencer naked, Derek was delightfully surprised at the size of Spencer’s manhood. It wasn’t as if Derek had expected him to be small, but Derek certainly never expected the eight-inch piston that sprang forward to greet him. If Derek hadn’t already claimed Spencer as his, he would have been jealous. Derek wasn’t without his own merits, however, and he noticed that Spencer seemed to appreciate them just fine. Whereas Spencer was long and on the thin-side, Derek was shorter and had much more girth when he was fully hard. Because of this, anytime the couple had penetrative sex, Derek had to prepare Spencer for a longer amount of time than Spencer may have needed to be prepared for another lover. Derek had gotten too excited and penetrated before Spencer was ready in the past, but that always ended up with Spencer bleeding and not being able to walk or sit properly for almost a day after.
Considering this, Derek took his mouth off of Spencer’s shaft and reached up to the bedside table where a large pump-bottle of lubrication sat. Spencer started to whimper in annoyance at being left unfulfilled, until he opened his eyes and realized what Derek was doing.
Derek laughed a little and shook his head at Spencer as he covered his fingers in the coffee-scented gel Derek had bought for Spencer as a Valentine’s Day surprise. “What do you want, baby?” he asked in a gravelly voice as Spencer started to pant and keen again, restless from the sudden loss of contact.
Spencer closed his eyes in concentration as Derek got back in his kneeling position. “I wa-want…” Spencer panted, “want you… inside m-me.”
Derek’s arousal increased exponentially at hearing Spencer say that, making him groan. His erection was almost painfully hard and heavy and he ached for contact and release, but he knew he had to get Spencer ready so he didn’t hurt him.
Derek bent down and licked up the underside of Spencer’s shaft before he took him in his mouth once again. He began to rub at Spencer’s sac with one hand, while with his other hand, Derek took his slicked-up fingers and traced a pattern down Spencer’s perineum and circled around his entrance. Then, without warning, he shoved his index finger into the small pucker and past the ring of muscles, making Spencer cry out loud.
Spencer seemed to finally find his voice as he loudly moaned, “Oh, god! Derek, I want you so bad.”
Derek smiled around Spencer’s member and hummed, making Spencer moan again. Derek slowly pumped and twisted his finger around in Spencer’s tight channel and as soon as he felt the muscles relax slightly, he added his middle finger and pumped a little harder. Spencer started panting again and Derek knew that he was quickly coming undone. Derek scissored his fingers and twisted his hand, trying to stretch his lover to compensate Derek’s girth before Spencer was completely overwhelmed. However, Derek’s fingers suddenly rubbed against Spencer’s prostate and it was all too much for the young doctor. Spencer came hard into Derek’s mouth without warning, but Derek only choked once before he swallowed everything Spencer had to offer.
Spencer’s whole body relaxed as he floated on his orgasmic high. He eventually opened his eyes and looked down at Derek, who was still trying to stretch his lover as he slowly trailed kisses up to Spencer’s belly button. When Spencer could speak again, he breathlessly said, “Sorry.”
Derek smiled and looked up at his lover and said, “Don’t be. I know you still have more in you.” He winked and chuckled slightly when Spencer softly moaned. Another thing Derek had been delightfully surprised about in the beginning was Spencer’s quick recovery time. Derek had gleefully discovered through trial and error that, if he pushed hard enough, he could make Spencer orgasm three or four times in one round.
When Derek added a third finger in his preparations, Spencer moaned louder and his member started to fill and become hard once again. Derek let out a breathy laugh and said, “Told you.”
Spencer rolled his eyes and groaned at Derek but that groan quickly became an impatient whimper as Derek removed his fingers. “Need you! N-now!” Spencer practically yelled as he grabbed Derek’s hips and wrapped his legs around Derek’s waist.
“Hold on, baby boy. Be patient,” Derek responded as he regretfully untangled himself from Spencer long enough to reach over for another pump of lube.
Spencer gasped and sobbed impatiently as Derek slicked himself up. After a moment, however, Spencer could feel the head of Derek’s erection pushing against his entrance. Spencer started to pant in anticipation as Derek slowly pushed his way into the tight, pulsing channel. Even though Spencer was fully prepared, the intrusion still burned and Spencer closed his eyes and hissed in slight discomfort.
“You ok, baby?” Derek asked as he halted his movement.
“Yes, yes I’m fine!” Spencer said impatiently as he wiggled his hips, silently telling Derek it was ok to keep going.
Derek nodded and continued slowly pushing forward until he was fully sheathed inside his lover. Derek looked down at the panting genius under him, admiring the beauty that was Spencer Reid overcome with pleasure. Derek was impatient to get started and to continue pleasing the man who had brought him so much joy over the years, but he refused to move without permission.
After a moment, Spencer opened his eyes and looked Derek in the face. Spencer then lifted his legs and hooked them on Derek’s shoulders. He took a deep breath and nodded his head.
Derek understood and gripped Spencer’s hips in his strong hands. He then pulled his shaft out until only the head was left inside the lithe body. He took a deep breath and made sure his grip was secure before he slammed back in, causing Spencer to throw his head back against the pillows and wail loudly. “Oh god, Derek! Harder! Please!” he practically screamed.
“With pleasure,” Derek responded breathlessly as he drew out again and then pounded back into his lover. He set a breathtaking pace, knowing that neither of them was in the mood for anything slower.
With each of Derek’s thrusts, Spencer pushed his hips down onto him, trying to take him further and further inside. He reached up to the headboard and tried to grasp onto something, needing something to anchor him as he slowly lost control of his body, letting passion and lust fully take him into sweet oblivion.
Derek, seeing the signs of Spencer reaching his peak, took one of his hands off of Spencer’s hip to instead grip his now straining erection.
Spencer moaned loudly when he felt Derek’s hand stoking his manhood in time with his thrusts. After a few strokes, however, the combined stimulation was too much and Spencer came violently, screaming in pleasure as long white tendrils coated Derek’s hand and Spencer’s stomach alike.
Derek continued to thrust erratically as he felt Spencer’s inner muscles clench around Derek’s shaft. A moment later, Derek gave one final push into Spencer’s hot body as he reached his own orgasm, groaning long and low as his molten seed shot into Spencer’s depths.
The next few minutes were filled with panting as the two men tried to catch their breaths. Derek shifted and extracted his spent member from Spencer’s channel, chuckling slightly when Spencer whimpered at the loss.
Spencer was almost asleep when Derek got off the bed to grab a wet rag from the bathroom. Derek had known before they started dating that Spencer put his all into everything he did, trying his best to be perfectly successful in each task. Derek was absolutely thrilled when he found out that this determination extended to lovemaking. When he and Derek were together, Spencer gave over everything he was and held nothing back, trusting Derek not to take advantage as Spencer made himself vulnerable to him (and Derek, knowing how rare it was for Spencer to trust anyone to that capacity, did not take this lightly and never wanted Spencer to regret that trust).
However, because Spencer did give his all to his and Derek’s lovemaking, Spencer often fell asleep rather quickly after his final orgasm. Derek really didn’t mind though. He took just as much pleasure in the after-care as he did in the act itself. That was why Derek still had a large smile on his face as he walked back into the bedroom, with the rag, and over to Spencer, who was not quite asleep but definitely still riding his pleasure high.
Derek gently wiped Spencer’s chest and stomach, moving slowly down to the more sensitive skin. Spencer moaned slightly as Derek cleaned his manhood and then moved down to his abused hole.
“Mmmmm… Derek?” Spencer questioned when he felt Derek gently washing his intimate areas with the wet rag.
“Shhhh,” Derek soothed as he continued his ministrations. “It’s just me, baby boy. Just relax.”
Spencer sighed heavily and did as Derek said, relaxing into the light touches.
When Derek was finished with Spencer, he quickly took the rag and cleaned himself off. Then he climbed into bed next to his lightly dozing lover and pulled Spencer in close. Spencer turned into Derek’s touch and laid his head on Derek’s chest as Derek slowly ran his hand through Spencer’s sweat-soaked hair. “I love you, Spencer,” he whispered.
Spencer mumbled softly and snuggled in closer to the warmth and safety that Derek provided.
Derek smiled and hugged Spencer tighter. Then he closed his eyes and joined his lover in sleep.
