Jack was lazily staring at the TV in the little living area for humans in Outpost Omega 1. Sundays are always slow and boring for Jack. But this Sunday is by far the most boring Sunday for Jack. He didn't have to go to his job today, Raf was at home because he got grounded for some reason and to top it all of the bots weren't at the base. Bumblebee and Bulkhead were out on a scouting mission, Arcee and Optimus had gone to check some recent Decepticon activities and Ratchet had left the base for some work. He was left alone in the base with Miko.

Miko for some reason is quieter than usual.

Unknown to the raven haired teen Miko was actually staring at him. She won't say it aloud but she had a crush on Jack. A really really big crush. She liked him a lot. But she knew that Jack liked someone else. Probably Sierra from highschool or his partner Arcee. But that didn't stop Miko from having feelings for Jack. She would do almost anything to be with him, even if it meant to share him with some other chicks.

"I wish you were mine Jackie boy." Miko thought.

She kept staring at Jack hungrily. Just then she had an idea.

"Maybe this can make you see me as more than a friend." Miko thought with a smirk.

"Today is so boring." Miko said, scooting over to Jack.

Jack eyed Miko as she scooted closer to him but didn't mind it. He looked back at the TV and said "Yeah."

"So, you have anything to do right now? Cause I am super bored." Miko said, leaning on Jack.

Jack felt all this was a bit weird but didn't mind it.

"Not really. I was planning on going on a ride with Arcee, but she went on a damn mission." Jack said.

"Uh huh. That sucks." Miko said and wrapped her right arm around Jack's neck.

"Hey, I have an idea. And I think we both will like this." Miko seductively said.

"What do you mean?" Jack asked as he turned to look at her.

Just then Miko quickly kissed him on the lips. This shocked Jack and before he could comprehend what's going on, Miko climbed on his lap and pushed him, making them fall on the empty place on the couch with Miko on top of Jack. She grabbed his face with both of her hands and started kissing him again.

"Miko! What are you doing?" Jack nearly yelled as he hoisted himself up with his hands.

"Relax Jack and enjoy this." Miko said and began kissing him again.

This time Jack's hormones took over and he decided to have some fun out of it. So he kisses Miko back and lets himself fall on the couch. They started making out. Jack groped Miko's ass with both of his hands making the Japanese teen moan. Jack pushed his tongue inside Miko's mouth and they began fighting for dominance, but Jack easily won.

"Looks like somebody is excited." Miko teased as she pulled away from Jack and sat on his lap, grinding her ass on Jack's, now half erect, dick.

"Maybe I should help you with that." Miko said as she crawled backwards a bit until her face was over his dick.

Miko bit her bottom lip as she saw how big the bulge was. She unzipped Jack's pants and pulled them down a bit and then pulled down his boxers and pulled out his dick. She gasped in shock when she saw how big he was and he wasn't even fully erect.

Jack grinned at Miko's reaction.

"Surprised?" Jack teasingly asked.

Miko gulped in nervousness and took the head of his dick in her mouth. She began sucking on it while bobbing her head as she jerked the rest of Jack's dick. It went for a few minutes and then Miko started deep throating Jack. Jack groaned in pleasure as Miko gave him a blowjob. Miko then felt Jack growing bigger, making it harder for her to deep throat him. But she didn't stop. The moans of pleasure coming from Jack were enough to encourage her. After a few minutes of sucking Jack was fully erect. Miko was shocked with how big his dick felt. Jack then suddenly grabbed her head and forced her to take all of his dick. Miko almost choked as Jack furiously lifted her head and slammed it back on his dick. But she slowly became used to it and started sucking him.

Jack was lost in pleasure. He has jerked off many times before, but that was nothing compared to the feeling of Miko's mouth and throat around his dick. He thrusted his hips upwards everytime he pulled Miko's head down, increasing the amount of pleasure he was getting. After 15 minutes of furious face fucking Jack slammed Miko's head down on his cock again, making her take all off the meaty appendage as he came. Miko was a bit freaked out at first when she felt Jack's hot cum in her mouth but quickly gulped it down. Jack came so much that it flooded her mouth. Some of his cum even leaked out her mouth.

Jack groaned in satisfaction as he let go of Miko's head and Miko pulled away from him. She coughed a bit and wiped the excess cum from her face and looked at Jack's dick. She was shocked to see it. It was almost 11 inches long and almost as thick as her wrist and was still rock hard even after cumming that much.

"Damn. That's a big dick." Miko said.

Jack just grinned at that as he got up and grabbed Miko and kissed her lips. He didn't put his tongue in her mouth because he didn't want to taste his own cum. As they were kissing Miko pulled the heim of Jack's T-shirt. Jack pulled away from her and she pulled the piece of clothing off his body. Miko lightly gasped when she saw Jack's body. He wasn't buffy but he was very muscular. He had a V shaped chest, 8 pack abs, 4D shoulders, and muscular arms. Miko was left gaping as she saw Jack shirtless.

Jack just chuckled at her reaction and pulled his pants off and began undressing Miko. He pulled off her T-shirt revealing her bra covered breasts and then undid her pants revealing her panties which were soaked with her juices.

"Looks like somebody is excited." Jack teased her.

"Shu-shut up." Miko stuttered as she looked away with a deep red blush on her face.

Jack grabbed her face and made her look at him.

"Maybe I should help you with that." Jack said and pushed her down on the couch.

Jack pulled off her panties and started rubbing her clit making the Japanese teen moan.

"You're so wet." Jack said as he felt Miko's moist foldes.

He then entered one finger in her pussy. Miko moaned at that as Jack started pumping his finger in and out of her. He then entered another finger. Miko moaned and arched her back in pleasure. Jack continued this for a few minutes hitting her G-spot until Miko came.

"Wow, you came fast." Jack said as he pulled his fingers out.

Miko was panting like crazy. She had no idea Jack could be this good at fingering a girl.

"Let's get to the main course, shall we." Jack said and put off her bra.

Jack fondled her breasts. They were a bit smaller than average but Jack didn't mind it. He found it cute. He then slowly began inserting his dick in Miko's pussy until he felt her barrier.

"Do it." Miko said encouragingly.

"Miko, are you sure? If we do this there is no going back." Jack warned.

"Just do it. I want to give you my first time." Miko said.

Jack leaned down and kissed her lips and thrusted hard inside her, breaking her barrier and taking her virginity. Miko grinned her teeth in pain as she tried to muffle her scream. Jack stood still for a few minutes until Miko told him it's okay to move. Jack then began thrusting inside Miko slowly. The pain soon turned into pleasure and Miko was left moaning. It encouraged Jack and he began thrusting harder and in no time Jack was pounding Miko hard. Miko was panting and moaning like crazy. Jack grabbed both of her arms in one hand and pinned them over her head, on the couch as he began thrusting harder and faster inside her.

The feeling of Miko's pussy was way too good. Jack kept pounding her for almost 20 minutes and Miko came. But Jack didn't stop there. He kept fucking her while she squirted her juices all over his dick. He then pulled out of her and flipped Miko so that she was now laying on her stomach. He grabbed her hip and pulled her up, making her do a submerged doggy pose. He then slammed his dick back inside her making Miko Yelp and moan loudly in pleasure. He continued pounding her harder and faster. Miko had her tongue hanging out as she moaned and panted. Jack leaned down and wrapped his left arm around her throat and began choking her as he fucked her faster and harder.

Miko was enjoying every minute of it. She liked how his dick filled her pussy completely. He even broke inside her womb at times which made her moan louder. She soon came and then came again. Jack kept making her cum over and over for a long time.

"I am gonna cum!" Jack yelled.

"D-do it……. inside...please…" Miko moaned as she pushed her backside against Jack's body.

Jack followed her request and came inside her. He flooded her inside with his hot cum. Miko's stomach bluged a little with how much Jack came inside her. After almost half a minute of releasing his cum inside her Jack pulled out. A stream of his cum leaked out of her pussy. Jack proudly looked at Miko's cum leaking pussy. But then he noticed her ass hole. Jack brushed his thumb against it and decided to go for it.

"This is gonna hurt a bit." Jack warned as he positioned himself behind her.

"Huh?" Miko said as she tried to understand what Jack meant.

Just then Jack slammed his dick inside her ass hole, filling up her ass completely. Miko loudly moaned in both pain and pleasure as Jack started pounding her like his life depended on it. Jack was having the time of his life. Miko's ass hole was much tighter than her pussy and it was taking him a lot of self control not to cum immediately.

"Ah! Ah! Ah! Ah! J-Jack!" Miko moaned as she came.

Jack inserted three fingers of his right hand in her pussy and started pumping them in and out while rubbing her clit with his thumb as he fucked the crap out of her ass. He grabbed one of her pigtails and yanked it, making Miko gasp and throw her head backwards. Miko was left breathless as Jack assaulted both of her holes. This went on for almost half an hour until Jack finally came inside her ass. His cum completely filled her ass up and even made it to her stomach. Her stomach bulged so much that it looked like she was three months pregnant.

Jack then pulled out of her and dropped on his back on the couch. With whatever strength Miko had left in her body she managed to crawl up on Jack and laid on him with her head on his chest.

"You did a number on me." Miko chuckled.

"Yeah, but what about you? I just came inside you. There's a high chance you might end up pregnant." Jack said with concern.

"Don't worry Jackie boy, my host parents like to fuck a lot. They have a huge stock of birth control and day after pills. I can easily steal one from them." Miko said as she rubbed her head against his chest.

"What about us? Look Miko, I do like you a lot. Probably more than a friend, but I am not sure about my feelings…" Jack said until Miko cut him off.

"Jack, I know that you have feelings for some other girls too. But I like you way too much. I don't care if you would go and date some other girl after this. I just want to be a part of your life and have a relationship with you." Miko said, surprising Jack.

"So you're practically saying that you are fine with me having more than one girlfriend. Are you suggesting that I get a harem?" Jack asked with a smirk.

"Maybe I am. Afterall a dick this good is meant to be shared." Miko said as she looked at her lover.

"Say you what, if we are in a relationship now, why don't we go back to what we were doing?" Jack suggested.

Miko giggled at that and got off Jack and walked over to the table in front of the couch with shaky legs and leaned on it, giving Jack a perfect view of her ass and pussy which were still leaking his cum.

"Fuck me like a bitch Jack." Miko said.

Jack grinned and walked over to her and positioned himself behind her. In a matter of minutes the whole base was filled with their moans and grunts. This went on for two hours and every time Jack came either inside her pussy or ass or mouth. They then noticed the mess they had made and Jack had to clean it up. Miko tried to help him but couldn't do much. After the cleaning was done, Jack took her to the bathroom which Autobots had installed in the base for their human friends. While cleaning themselves, Jack and Miko made love for another 30 minutes.

Later that day when the Autobots returned and they were sent back home, Jack had a huge grin on his face. This was by far the best weekend he ever had and he was looking forward to meeting Miko tomorrow.

(Next pairing:- Jack x Sierra)
