James Tiberius Kirk had many virtues not limited to a great sense of leadership and a high intelligence but abstinence was certainly not one of them which explains why he had a lap full of a gorgeous, green eyed man grinding against his , he had to admit being in star fleet was going better than he thought it would, meeting the green eyed man seemed to be the highlight so far. Not to mention his friendship with Bones. But the later can be easily ignored as the former demanded his immediate attention."Fuck, Harry." He breathed out when a hand slipped past his waistband an palmed his erection. "You're gonna drive me crazy.""That's the plan." The green eyed minx smirked as he pulled back for a second to pull off both of their shirts before locking their lips decided that the bedroom was more suited for what he planned to do to the other man and with great strength held a firm grasp to the other man's thighs and pushed forward until Jim was on his feet and Harry had his legs wrapped around his waist. The other man gave a breathless laugh before burying his face in Jim's neck and nibbled at it making Jim move quicker towards the bedroom, where he threw the other man on the bed and helped Harry remove his trousers and pants before working on his own. Jim looked at the body spread out on his bed, his eyes intent on the way the slim body stretched and how those hands didn't stay idle and ran down the body they belonged to. Jim broke his stare when Harry spread his thighs invitingly to the slightly older man, he couldn't seem to resist the invite in those green eyes. They both moaned at the feeling of their bodies connecting, hard members sliding against each other.

"You're being so pushy today." Jim groaned against Harry's ear as the younger man kept grinding against him.

"I'm in a good mood." Harry smirked up at the other man, his lips swollen from Jim's attention earlier. Jim grinned down at him before huffing when he suddenly found himself on his back and an energetic minx straddling his waist.

Harry ran his hands down Jim's chest, pinching his nipples lightly before he made his way down and wrapped his hand around Jim's hard member.

"Fuck!" Jim swore as a hot mouth joined the hands wrapped around his cock and sucked on the head lightly before inching down slowly then back up. He buried his hands in raven hair and closed his eyes as the owner of the mouth masterfully played with him. Edging him continuously until he became incoherent, not even hearing the sound of the lube bottle snapping open.

Jim groaned when the hot mouth left his cock but he didn't feel disappointed for long as another type of heat encased his member. He looked up and was momentarily stunned by the younger man sitting astride him with his head lolled down and hid lower lip being bitten by pearly white teeth, failing to stop the moans from spilling out of the sinful mouth as he moved up and down on Jim's cock.

"Fuck!" Jim cursed again before suddenly surging upwards and turning so that the younger man was on his back driving into him with a force that shook the bed.

"Jim!" Harry cried out, hands gripping Jim's shoulders as the older man kept hitting his sweet spot. "Fuck!"

"You have no idea how much you turn me on." Jim grunted as he felt blunt nails run down his back. "You and your coy attitude around everyone." Jim grinned down at the wide eyed younger man. Finally, gaining the tiniest bit of composure as he took the lead. "You have no idea how mad it makes me seeing you be that way with everyone."

"No!" Harry gasped, his hands now thrown back against the headboard to stop his head from banging it. "I don't…." A loud moan interrupted him as Jim buried his cock inside of him and kept grinding against him.

"You do!" Jim growled, going back to his rough fucking. "And you know how it affects me." Jim reached with one hand and buried it in the raven's hair, tightening his hand and pulling back until Harry's green eyes met his. "You fucking love it."

Jim crushed their lips together in a kiss filled with battling tongues and biting teeth. Harry pulled back and yelled Jim's name while he came while Jim bit down on the juncture between Harry's neck and shoulder to muffle his shout as he came. He let himself fall on the younger man when he was done who buried one of his slim hands in Jim's blond hair while the other started to run up and down his back.

"I should put you in a good mood more often." Jim muttered against Harry's sternum as he finally caught his breath.

"And I should rile you up more often." Harry laughed breathless, looking down at the older man who rose his head when he heard him say that.

"Please don't." Jim groaned before he laid back down on Harry's chest and kissed his shoulder softly making the younger man shiver.

"Are you saying that we're exclusive now?" Harry smiled, his eyes closing as Jim continued to bestow kissed down his sternum.

"We better be." Jim rose up and kissed Harry's lips sensually, easily slipping his tongue inside when Harry gasped.

"Round two?" Harry moaned feeling the member inside his hole harden.

"Hell yeah!"

Jim had never felt like this before with anyone. He liked talking to Harry, he liked spending time with Harry, he liked studying with Harry and he definitely liked sleeping with Harry.

But, this relationship seems to be similar to many things that happened in Jim's life. Too good to be true.

He had bumped into Pike after leaving one of his classes and he was having a very engaging conversation with his mentor when suddenly out of nowhere a raven haired blur jumped into his mentor's arm.

"When did you get back?" The sound that asked that question was familiar to Jim, as well as that sexed up raven hair.

"I just got back." Pike smiled down at the young man that still had his arms on the older man's shoulders but their bodies were separated. "I was making my way to see you when I bumped into Jim here."

Jim stood wide eyed and speechless as green eyes turned towards him and lit up as they met his.

"Jim, have you met my son, Harry?" Pike's question woke Jim up and he looked from father to son before Harry beat him to the answer.

"Of course we met," Harry rolled his eyes at his father and smiled at Jim. "He's my.."

"Friend!" Jim interrupted, not meeting Harry's eyes. "Our dorm rooms are next to each other."

"That's nice." Pike answered hesitantly his eyes moving from the nervously smiling Jim to his glaring son.

"I have to go." Jim suddenly declared, he quickly turned around and left.

"Is something going on between you two?" Christopher asked his son who was staring at the quickly retreating back of one James Tiberius Kirk.

"Apparently not." Harry's frown deepened before he erased it and smiled up at his adoptive father. "Let's get lunch."

"Bones!" Jim burst into their dorm room has face panicked and started pacing.

"What have you done now?" Leonard didn't even lower the book he was reading as he answered the other man.

"Harry is Pike's son!" Jim exclaimed, stopped pacing and moved to sit at the foot of Leonard's bed where he was lying reading his book.

"And?"

"What do you mean and!" Jim groaned burying his head in his hands as he tried to think of what he was going to say. "I can't date Pike's son!"

"Why not?" Leonard turned a page.

"Are you even listening to what I'm saying?" Jim huffed as he looked up and found his friend deeply engrossed in read his book.

"Yes." Leonard muttered, turning another page. "Harry is Pike's son and you can't date Pike's son, yadda yadda."

"Don't mock me!" Jim stood up and threw himself on his own bed face down.

"Jesus!" Leonard rolled his eyes before he set his book down and sat up. "You like Harry, you asked him to be exclusive and you have been sleeping together for the better part of five months. Why should it matter that Pike is his dad now?"

Jim mumbled intelligibly into his pillow making Leonard huff and throw a pillow at him.

"Be normal for once in your life!" Bones was done faster than usual with his antics today it seems.

"I said," Jim huffed turning his head to look at Bones. "I bumped into Pike.." and he proceeded to tell Bones the whole encounter that happened and hour ago.

"Every time I think you're idiocy has reached the limit," Leonard groaned, burying his head in his hands. "You seem to keep breaking that limit."

"I know." Jim moaned in misery, throwing himself back on the bed. "What am I gonna do?"

"What do you want to do, dumbass?" The older man rubbed his face feeling extremely frustrated.

"Why am I asking you if I know what to do?" He huffed turning on his side to look at his best friend.

"Do you want to keep seeing Harry?"

"Yes." Jim whispered.

"But?" Leonard huffed, rolling his eyes.

"What about Pike? He's my mentor." Jim sighed suffering as he sat up.

"But Pike has nothing to do with you dating Harry." Leonard pointed out. "Unless you're in love with Pike?"

"What?!" Jim exclaimed, standing up. "He's more like a father than anything else."

"Then get the fuck out and go apologize to the poor man that has to have you as a partner." The older man stood up and went back to his own bed, laid back and returned to his book.

"I think you're right." Jim smiled at the huff the man let out. "Thanks, Bones." He yelled back as he ran out of the door.

"Dumbass." Leonard huffed to himself, a little smile on his face.

Jim looked everywhere for Harry and had yet to find him. He wasn't in his dorm room, he wasn't in the recreation room and he wasn't answering any of Jim's calls. He went back to his room and sat miserably on his bed. Until Bones dragged him out to the bar they frequented which he was not in the mood to be in.

"Bones, I'm not feeling up to being out currently." Jim struggled against the older man's hold as he marched him inside the bar. He was about to put more effort to escape when he caught a glimpse of the bar.

To be more exact he caught a glimpse of Harry sitting on one of the bar stool with some ensign all over him.

"What the fuck?" Jim exclaimed, moving towards where his boyfriend sat. "Who the fuck are you?!" He pulled the ensign away until he stood away from Harry.

"What do you want Jim?" Harry stood back up and moved towards the ensign. "This isn't any of your business."

"The hell it isn't!" Jim exclaimed, glaring at the ensign when he placed his arm around Harry's waist, feeling a bit satisfied when Harry pushed it away. "I thought we were exclusive."

"Oh," Harry raised a brow. "We were, were being the operative word because you didn't want us to be."

"Harry," Jim stared pleadingly at the younger man. "I'm sorry, I panicked."

"You panicked?" Harry repeated syllable by syllable. "You stood in front of me and told my father and I quote 'I am a Friend, our dorm rooms are next to each other.' How was that supposed to make me feel, did you even think about that?"

Jim looked so crushed that Harry just sighed and walked out not turning back when Jim followed him. But Jim it seems had other plans because he quickly caught up with him and grabbed his arm.

"Please, Harry," He pleaded, holding the other man's hands against his chest. "How can I fix this?"

Harry stared back at the older man for a long moment before he finally spoke.

"You can make it up to me by telling the truth." Harry said looking pointedly behind Jim.

Jim slowly turned around and found Commander Pike standing behind him with crossed arms and a raised eyebrow.

"Um," Jim swallowed, his throat feeling dry all of a sudden. "Sir." He greeted with a nod receiving one in return.

"Kirk." Jim winced, Pike always called him Jim.

"You see," Jim fidgeted for a minute before he turned towards the older man and offered his hand. "I'm dating your son." Jim internally winced.

"Is that so?" Pike asked, alternating between looking between Jim's hand and face before finally shaking his hand.

"Yes, sir." Jim choked out, gulping at the tight grip.

"Dad, not again." Harry warned from behind Jim, but Jim didn't feel himself ease at that bit of information, 'not again'.

"Oh don't worry Harry." Pike smiled at Jim and released his hand. "I'm sure me and Kirk can reach a suitable agreement."

"Yeah, right." Harry huffed before pulling Jim away from his father and towards their dorm.

"That was the most terrifying moment of my life." Jim finally spoke as they reached Harry's solo dorm room and sat on his couch. He buried his face in Harry's chest and groaned.

"I'm sure you'll live." Harry rolled his eyes but even so, he started running his fingers in the blond hair. "I haven't totally forgiven you yet."

"I know." Jim hummed as he moved his face to nuzzle against Harry's neck, lavishing the place with little bites and kisses. "I'm at your mercy."

"You are?" Harry hummed as Jim reached a sensual patch of skin that made his toes curl. "I hold a grudge, you know?"

"I know." Jim slowly started placing kisses upwards towards Harry's lips, pecking them a few times before he passionately started kissing the younger man. Easily slipping his tongue inside the other's mouth as he moaned. "I'll make it up to you."

"How about you start now?" Harry pulled Jim away by his hair and smirked at him, he pushed him away and stood up leading Jim towards the bed and pushed him down before he sat astride the blond man.

Oh, Jim would very much like the type of apology Harry wanted out of him.
