After his shift, Kirk quickly made his way back to his quarters. He stripped off his command shirt along with the rest of his uniform. Kirk went into the fresher and stepped into the shower. He turned the hot water on and moaned in relief when the water hit his tight muscles. Kirk closed his eyes and tilted his head forward so that his neck bore the brunt of the water's onslaught. After the shower, he quickly dried off and put on a white cotton t-shirt and gray sweatpants. Kirk laid down in his bed, reveling in its softness and comfort. He closed his eyes and let himself forget about his long day. He brought a hand up to his swollen belly and thought about his baby. Kirk wondered if it would have Spock's slanted eyebrows and pointed ears. God he hoped so. He also wondered if the baby would inherit Spock's love of science and music or his own love of literature and basketball. Kirk smiled softly to himself and pictured his son or daughter shooting hoops with him in the morning and playing Spock's lyre under Spock's guidance at night. He drifted off to sleep with a smile on his lips.
Kirk started to wake up when he felt light touches. He cracked an eyelid open and was able to make out somebody lightly kissing his rounded abdomen. Kirk opened both eyes and watched Spock nuzzle his face against his soft, velvety skin with reverence. Looked like Spock was finished working on his latest experiment in the labs.
"Hi there," Kirk said, voice rough with sleep.
Spock sat up and met Kirk's eyes with his own. Kirk's stomach flipped when the soft chocolate gaze looked at him warmly. Kirk pushed himself up to be face-to-face with his mate. He held Spock's face in his hands and softly kissed his bow-shaped lips. Spock released a moan from his throat and responded to the kiss. Spock's hands gripped Kirk's wide hips and pulled his body closer to his own. Spock whimpered when Kirk's distended stomach met his. Kirk smiled against Spock's lips. Kirk knew that Spock loved his changing body as it accommodated the growth of their unborn child.
In one fluid motion, Spock pushed Kirk onto his back and placed himself above Kirk. The two men gazed at each other in meaningful silence before Spock broke the spell.
"Are you fatigued?" Spock asked with a furrowed brow. Spock's face was otherwise completely neutral, but Kirk knew Spock was concerned. It hadn't been an easy pregnancy. Almost chronic morning sickness early in the pregnancy made it impossible for Kirk to keep anything down, and it was unknown whether Kirk would survive the stress his body was in. Kirk recovered, but fatigue and low energy, however, continued to plague the captain.
"Yes, but right now I would prefer it if we continued what we started," Kirk said suggestively. He wiggled his eyebrows up and down for added effect.
It had been too long since he and Spock had sex, and he had it denying Spock and himself the intimacy that they needed. He flashed his signature and very effective Kirk smile and knew that Spock couldn't resist him now.
Spock first slowly divested Kirk of his clothing. Spock kissed and grazed newly exposed skin with his lips, teeth, and tongue. Kirk moaned as each touch added to the fire that burned deep within his belly. Spock removed Kirk's regulation boxers and admired his mate's naked body as if it was a table of food waiting to be devoured.
Kirk, however, was getting impatient. He grabbed the hem of Spock's shirts and quickly pulled them both over his head. When Kirk saw Spock's head he couldn't help but laugh. Spock's normally pristine hair now stood on end thanks to static electricity. Spock looked at Kirk with a touch of exasperation before he covered Kirk's lips with his own. Kirk continued to laugh in the kiss, but Spock eagerly swallowed down Kirk's happiness and amusement. There was nothing better than a contented mate.
Spock broke the kiss to shed the last pieces of clothing before reattaching himself to his husband. He buried his face in Kirk's neck and inhaled deeply, basking in Kirk's scent before he lightly bit the soft skin. Kirk felt his toes curl and pleasure shoot through his full cock. He felt Spock's answering erection graze his thigh. Kirk brought a hand up to Spock's hair and lightly pulled his head back and brought Spock's lips back on his own. The kisses became more passionate and demanding. Spock pressed Kirk further into the mattress and Kirk arched his back to feel more of Spock's skin against his. Their erections brushed against each other. Spock moaned against Kirk's mouth and shivered in arousal. He couldn't help but thrust against Kirk's cock and belly, wanting to feel that friction. Kirk absolutely loved it when Spock allowed himself to let loose and express the pleasure he felt. Kirk felt pride knowing that only he was allowed see Spock like this.
Spock pulled away from Kirk's red, swollen lips to kiss his way down Kirk's body, which was humming in bliss. Spock took one of Kirk's nipples into the wet heat of his mouth and swirled his tongue around the hardened nub. Moans and whimpers fell from Kirk's lips, music to Spock's ears. Kirk stroked Spock's silky, jet black hair, messing it up further but Spock was too occupied to care. The Vulcan gave the same treatment to the other nipple before continuing south. Spock lovingly caressed the skin of his mate's pregnant belly, reveling at its healthy size and feeling his unborn offspring move within. It was uncertain whether the pregnancy would progress further than the first trimester. There was also the chance that the pregnancy would need to be terminated to save Kirk, who was dangerously dependent on modern medicine to keep his body hydrated and nourished. Fortunately, they decided to wait before taking any drastic measures. Kirk's health greatly improved fourth months into the pregnancy and the pregnancy progressed normally from that point forward.
Now at seven months, both the baby and Kirk were perfectly healthy, much to everyone's relief. Spock could feel their child move within his mate's almost perfectly round abdomen. Kirk reveled in Spock's gentle and loving touches. He loved feeling his husband's strong hands on his swollen belly. He felt both safe and vulnerable at the same time underneath Spock.
Kirk loved the attention his sensitive belly was getting, but he was getting impatient. They hadn't had sex in a while, and he was definitely planning to get some, especially since he was definitely in the mood for it. Besides, Spock already touched his belly constantly whenever they were in private. Kirk wrapped his legs around Spock's waist and thrust his ass against him, hoping to send the message across.
Spock raised his eyes to meet Kirk's and raised an amused eyebrow, which Kirk responded with a sheepish smirk. Spock wordlessly unwrapped Kirk's legs from his torso, bent them at the knee, and placed the bottom of his feet on the bed. He reached for the lube from the bedside table and uncapped the bottle. Spock generously coated his first finger with lubricant, capped the bottle, and set it aside for later use. He found Kirk's opening and slowly opened the tight ring of muscle. Kirk let out a few hisses of pain. Spock apologized to his mate by soothingly stroking his leg with his free hand. Kirk focused on Spock's touch and breathed deeply through his nose. He closed his eyes and forced himself to relax from head to toe. Kirk felt himself loosen and open to allow Spock's finger further enter his body.
"We definitely need to do this more often," Kirk sighed, getting impatient. They used to have sex often enough that Spock didn't need to prepare him before entering.
"Not if the risks outweigh the benefits," replied Spock calmly, as if he were on the bridge and not with a finger partially up Kirk's ass.
Spock crooked his finger at an angle, and was greeted by a deep moan of appreciation from Kirk. Spock himself released a few moans himself. His sensitive finger was embraced by Kirk's tight heat. Spock added a second finger to further open his mate's body while making sure to graze against Kirk's prostate, much to Kirk's delight. Once Kirk was deemed sufficiently prepared, Spock coated his erect member with lubricant and positioned himself at Kirks opening. Spock's eyes met Kirk's in askance. Kirk nodded hurriedly, just wanting Spock to be inside him.
Spock pushed into Kirk while gripping his mate's hips, which caused both of them to moan appreciatively. Once Spock was sheathed to the hilt, he loomed over Kirk and placed both hands on either side of Kirk's head. They were face to face. Their pupils were blown wide open with arousal. Kirk brought a hand up to Spock's face and smoothed a thumb over a cheek bone. Spock closed his eyes as his head leaned into Kirk's hand for more contact. Kirk then brought a finger to one of Spock's ears and traced its alien shape. Spock bent his neck downward to nibble lightly on one of Kirk's ears. Kirk stroked Spock's back and occasionally ran his fingers through his thick, soft hair.
"You can move, you know," Kirk said with a smile.
Spock responded with a small smile of his own before he thrust into Kirk. Kirk's back arched in ecstasy as he was filled completely by his husband. Spock's cock grazed Kirk's prostate, which caused Kirk to release a string of obscenities from parted, swollen lips. Spock continued to powerfully thrust into Kirk's pliant body. Spock, however, only gave Kirk as much as Kirk would enjoy. Never more. Spock knew that Kirk had tolerated much more from previous lovers, but tolerating was not the same as enjoying. Through their skin contact, Spock could sense that his mate was thoroughly savoring their current activities.
Kirk clenched his muscles and moved his hips to meet Spock's thrusts. Spock threw his head back, exposing his milky neck and throat and clenched his eyes shut. Kirk couldn't help but lick and bite at his vulnerable skin. The Vulcan released a shiver as pleasure coursed through his body and a deep moan escaped his throat. Kirk bathed in his husband's pleasure, which was pouring off him in waves. Combined with his own bliss, Kirk was at the precipice. His cock, trapped between his and Spock's bellies, was achingly hard. He desperately wanted to cum, and now. Spock, he knew, had incredible stamina and could keep thrusting into Kirk several more minutes without stopping, but Kirk couldn't wait that long.
"Please, let me…I need -" Kirk breathed, his words caught off by a soft moan.
Spock could easily have let Kirk suffer more, bringing him closer and closer to release without letting him orgasm until much later. Kirk had done exactly that to Spock multiple times, unraveling him at the seams until Spock was just a whimpering bundle of nerves completely at Kirk's mercy. The thought of having Kirk beg him shamelessly was extremely seductive and arousing, but Spock had decided against being cruel, especially when Kirk desperately wanted and needed this.
Spock reached between his and Kirk's bodies and wrapped a hand around his cock without his thrusts losing their steady rhythm. Kirk hissed when Spock touched the overly-sensitive skin of his penis. Spock used the drop of pre-cum at the tip of Kirk's member to lubricate and facilitate Spock's strokes. Kirk growled and pulled Spock down for a kiss full of teeth and tongue. Spock answered with his own growl as he sped up his thrusts and strokes. The pool of heat in their bellies grew. Kirk choked out a sob when it became too much. He arched his back, desperate to feel more of Spock's skin against his. Their shared pleasure continued to escalate until both men felt white hot pleasure from their bellies radiate to their entire bodies. Spock filled Kirk with his seed while Kirk painted his own round belly.
The aftershocks of the shared orgasm left the two men shaking. Spock couldn't help but rest his upper body on Kirk's to recover. Kirk accepted Spock into his arms and caressed the length of his back. He kissed what he could of Spock's head, which was resting against his shoulder.
"I will have to give you a commendation for that performance, Mr. Spock," sighed Kirk. His sated, boneless body sank into the bed.
"I do not believe bringing a superior officer to orgasm is part of my duties, Captain," Spock said softly as he nuzzled against Kirk's neck while kissing the soft skin.
"I will write to Starfleet Headquarters demanding the duties of first officer be updated," Kirk said in an almost serious tone.
"You will do no such thing." Spock wrapped his arm around his husband tightly to prevent him from moving and sending ill-advised messages to the admiralty. "However," Spock continued, "it is a part of a husband's duties to bring his mate to orgasm."
"Fuck yeah it is," Kirk laughed.
The pair rested in each other's arms a few more moments before they got up to take a shared shower. After they washed themselves, Kirk couldn't help but marvel at Spock's body underneath the spray of warm water. Spock's face was raised, facing the water with eyes closed. As a member desert species, he placed high value on value and was taught to conserve it as much as possible. However, when water was abundant as it was on the Enterprise, Spock tended to indulge. Kirk remembered having especially steamy showers and baths with Spock. Fuck, no wonder he was pregnant. Kirk's eyes traveled from Spock's peaceful face down his strong yet elegant neck, which flared out to broad shoulders and powerful arms. Kirk shivered with remnants of arousal at the sight of Spock's sensual body. His cock twitched interestedly between his legs, but Kirk no longer had the energy for another round.
Spock slowly opened his dark eyes and turned his head to face Kirk. Kirk's stomach flipped as it often did when Spock looked at him. Spock neared him and backed him up against the wall. His arms raised to place his hands on either side of Kirk's head, caging him in. Spock leaned his head down to rest his forehead against Kirk's. They closed their eyes and enjoyed this tranquil, quiet intimacy they were sharing.
Kirk kissed Spock chastely and broke their quiet moment.
"If I don't go to bed right now I am going fall asleep on my feet," Kirk whispered, opening his eyes.
"Perhaps I shall leave you to sleep here so that I may be able to have adequate room on which to sleep," Spock said, an eyebrow quirked.
"Hey! I do not hog the bed."
Spock only shot him a blank look.
"And if I do, it is completely your fault," Kirk said, pointing to his expanded belly, his own eyebrow raised.
"You hogged the bed before we conceived, Jim and I believe you were active in the conception of our child," Spock said, leaving the shower and grabbing two towels.
Kirk scoffed and rolled his eyes.
"In that case, why don't we just sleep in separate beds?" Kirk asked.
"Because it is highly unlikely that either of us would have a restful sleep cycle if we slept apart," Spock said matter-of-factly while handing his mate a towel.
Kirk couldn't help but smirk. Spock might act prickly sometimes, but Kirk knew he had Spock wrapped around his finger just as Spock had Kirk wrapped around his own finger.
Spock threw him a soft look that confirmed his theory.
He and Spock dried off and dressed in pajamas. Kirk climbed into bed and sighed with relief. Spock climbed into bed and pulled the covers over them. Kirk automatically curled around Spock. Spock pulled Kirk closer and rested a hand on Kirk's swollen belly, branding the baby and Kirk as his. Kirk brought a hand up to cup Spock's face and kissed his soft lips before resting his head against Spock's neck. Spock ran his other hand up and down Kirk's back, which quickly encouraged Kirk to leave consciousness behind.
