AN:Update time! FYI I haven’t quite figured out the cybertronian x human practices of intercourse just yet, I always pegged Cybertronians to be somewhat organic underneath some of the armor plating, but if that ideas fizzles out I will use my human-former idea with Arcee and Arachnid. Either their robot forms will techno-organic transform into human ones or they could use an ‘avatar’ body of synthetic organic flesh. Complicated I know, still working on it. In the meantime here’s some Jack/Sierra for chapter two.
Jack’s Girlfriends
Chapter Two: Seductive Sierra
By Jehuty-Prime
It was another day at school and part of Jack Darby was actually looking forward to it. Sure the classes were rather uninteresting as they usually tend to be, but one person in particular within chemistry class highlighted his day of hopefulness; Sierra.
He wasn’t going to lie, part of him was just as eager to head to Autobot base where MIko was, since their recent change in their ‘friendship’ the girl would not stop texting him or sending pictures of her tits or bare ass. She constantly gave not-so-subtle hints at wanting some alone time with Jack whenever they had an opportunity. Even though she hardly left Jack alone she made it clear that this was merely a ‘sex-friendship’ they were having and that he was okay to go for Sierra, but he just wasn’t sure she was being honest with herself when she said it.
Despite how much of a troublemaker she usually is Miko can look rather beautiful and alluring whenever she looked directly into his eyes. quickly shaking this train of thought Jack sat upright when the teacher walked around the classroom to make sure none of his students were sleeping.
He looked up ahead to see Sierra’s back as she herself sat upright suddenly, his eyes drooped and he sighed whenever the girl looked at him directly during their seldom encounters. If he hadn’t had the Autobot base to go to everyday then he would be around more in Jasper where she and him could talk more often and eventually hook up. That was daydreaming at best, but for some reason he was feeling lucky today, ever since the pink Energon incident he was feeling more confident in his ‘lady luck’. Especially after having sex with Miko shortly after, Jack still didn’t know what to label this circumstance as just yet, but he pegged it as having some kind of ‘chick magnet’ field attached to him due to the Pink energon.
‘Maybe I’ll ask Ratchet later and tell him what happened, there might be a way to get rid of whatever this is before things get chaotic, but…’ Jack thought to himself and looked forward at Sierra’s seat one more time only to see the redheaded sweetheart looking back at him with a smile. ‘Scrap it, a cure can wait, right now my main goal today is ask Sierra out.’ He finished his thought when the class bell ended.
Little did he know Sierra herself was feeling ‘different’ today as soon as chemistry class started, she snuck a few looks over at Jack who was jotting down some notes. She sighed, she had wanted him to ask her out for some time yet there were so many intrusions in daily life. One of which was that he was hardly ever around in Jasper, or at least in the more student heavy places like the mall or skate park. Her blonde friend somewhat disapproved of him and Sierra herself was guilty of hubris due to the popularity circle she unwittingly became a part of.
She was the ‘popular’ girl in school meaning a lot of guys were pining for her and the ones she wasn’t interested in might pick fights with Jack if she showed her interest in front of them. She figured with him and his mother trying to live without problems that he didn’t need that kind of attention. So she sought out her crush during after school hours when no one else was around, like when he is at his job and she goes there to talk to him.
Of course sometime recently her enthusiasm became somewhat deflated when another ‘girl or woman’, she wasn’t sure, was sharing time with Jack.
‘That couldn’t have been his mother, could it? I mean borrowing his motorcycle is one thing but wearing a leather jump suit is a bit odd for a nurse who’s working all the time.’ She thought doodling a heart in her notebook as she looked at him from the front. She quickly turned away before any of the classmates would take notice and give them childish trouble.
She felt a strange feeling over her, like she was more confident and a bit sensitive down there, Sierra couldn’t be patient. Not anymore at least, today after class she would talk to him to see if there was another person in his love life, if not then it would be her moment and nothing would deter to her. Not even the sudden urge to rub herself off at the thought of Jack and her alone.
‘Where did this feeling come from? It’s like my body is suddenly set to ‘wild libido’ mode or something.’ She wondered and ignored it the rest of the class with enduring discipline.
After class was over and the school day ended Jack volunteered for cleanup duty along with Sierra that afternoon. Normally the teacher does it, but the worn out chemistry professor wasn’t about to pass up a chance to go home early. So he left the classroom and thanked Jack and Sierra before heading out, the two teens stood awkwardly next to each other while they picked up this and that.
A couple of minutes passed, during which Jack received yet another text from Miko about when he’s coming to base. Arcee was out on a mission and Jack was originally going to ride with her and Bulkhead later today, but plans changed since he was finally alone with Sierra for once. He texted her back and told her to go on ahead without him and let her know that he was going ‘for it’ with the redhead today. Miko knew he would but still sent a frowning smiley face back to him in a text.
‘What is it with that girl? Must be the jealous type or maybe she’s feeling the urge and needs me there to accommodate. That girl is as horny as she is hyper.’ Jack figured and stooped over to pick up a textbook when Sierra coincidentally did that same thus leading to their hands touching.
He blushed a bit and stared back into her delicate face with a genuine smile. After a moment of awkward silence he lifted his hand and let her pick up the book, the two stood facing each other until one of them spoke.
“So…I’m free now, feeling going out for a shake?” Jack asked feeling like he could’ve said a better pick up line.
“Of course, but I kinda want to know something first.” Sierra asked sheepishly looking to the side.
“Sure, what is it?”
“Are you together with someone?” She asked hoping he said ‘no’ and that the woman at the drive through really was his mom, albeit it was a weird idea for a nurse to wear a jumpsuit straight off work.
“Not at all, that woman at the drive through is definitely not my girlfriend, on that you can trust me.” Jack answered and sensed relief coming from her.
Feeling bold he decided to just straight out ask her. “Sierra, would you go out with me?”
Her face lit up and suddenly all the books she was holding fell to the floor because her hands clamped together in joy. “Yes! I mean I totally want to if you feel like it.” She played off the last bit coolly trying not to look overexcited but that failed her.
“Of course I do, I’ve wanted to ask you out for the longest time, but I’ve just been so-“
“Distracted?” She finished for him leaning in close in an intimate way. Her hands touching the fabric of his shirt affectionately. The pink Energon radiance would soon push things into their extreme and neither of the two would have any idea, not that they would care all that much since they were in each other’s company.
“Yeah, in a way, but honestly-“ Jack was cut off when Sierra suddenly pressed herself forward and smothered his lips with hers. The unexpected surge in sexual promiscuity was brought on by the Pink Energon Jack was radiating, his hormones in turn were about to go nuts as well in this premature action after barely agreeing on a date with the girl. He didn’t care, he just wanted her.
He wrapped his arms around her and leaned in to the kiss and felt her soft pink lips cuddle on his in a heated lip lock of unrestrained desire. Things soon fell into motion.
Jack was living his fantasy alright; his redheaded eye of affection had her hands underneath his shirt stroking along the skin of his back and torso while he pressed against her kissing along her neck.
They were in an empty classroom of Jasper High after school hours, only Miko and Raf were around yet they were out in the front waiting for Bee and Bulkhead to pick them up. Arcee would come for him soon too, so he had to make this quick, much to his dismay.
Sierra’s right left leg hiked up and curled around his calves as the heat of the moment started increasing the longer the two felt each other up. The redheaded cheer captain slowly opened her eyes from the state of bliss she was currently experiencing and looked down into Jack’s blue eyes before nodding.
She had just gave him ‘full access’ permission when he was still just treating her delicate skin with the soft touch of his hands on her thighs along with his lips at her neck. Her purple skirt now nudged upward letting jack see the white of her panties coming into view.
While he was distracted by the view of her curvaceous petite legs Sierra took that opportunity to quickly pull her long-sleeved/t-shirt combination up over her head as a means to surprise Jack when he looked back up at her.
Needless to say he got the shock of his lifetime when he turned his view back to Sierra’s now naked chest staring back at him.
Sierra giggled when she saw his jaw drop, truly she did have a good level of self-confidence but often felt insecure about her natural assets, she was glad to see that Jack appreciated them plenty. Boy was she glad she decided not to wear a bra today.
“Sierra…” Jack trailed off when his eyes stuck on her ample B-cup size boobs that were actually a bit larger than Miko’s.
“Like what you see, Jack?” She asked with a lusty gaze and alluring voice before putting her left hand under his chin seductively. His head lifted up to meet her loving gaze in her green eyes, his hands still held her hips and the two were pressed comfortably against each other against the wall of the classroom.
“You bet I do, then again I liked everything about you since the start of this school year when I saw you in class for the first time.” Jack confessed losing himself in her stare.
Sierra blushed, she had known that because of her looks and cool casual stature that boys often stared at her when walking down the hallway. More likely they were staring at her ass when her hips swayed, but that kind of attention got old real quick when some of the more perverted admirers tried taking revealing pictures of her in the locker room or when she was sitting down somewhere with her legs uncrossed. Thankfully her friend, Annie, the blonde best friend that is often seen next to Sierra, made sure none of the perverts ever kept the pictures they took. Either by breaking cellphone cameras or punching their lights she always made sure to have her friend’s back and prevent any perverse imagery to reach the internet.
The redhead sweetheart got bold and grabbed Jack’s wrists up off her hips so she could place them on top of her breasts. Miko did this exact same thing when she and Jack were ‘starting’, but now it was different simply because it was Sierra; the girl he’d been crushing on all year.
Jack played with her orbs a little more by stroking them in multiple directions eliciting a hearty low moan from the redhead. While he was playing with her breasts she sneakily slid her hands down to his zipper and undid the top of his pants shortly after.
Jack momentarily ceased stroking her tits when he noticed a cool breeze of air flowing across his now outstretched member. Sierra’s fingers fiddled and played around with the Jack’s sensitive shaft while he in turn played with her touch-sensitive mounds.
The heat of the moment increased in the midst of the foreplay leading to Jack pressing himself forward against her body boldly so he could wrap his lips around hers again. She accepted with just as much enthusiasm by wrapping her arms tightly around his neck and letting his tongue dive past her lips.
Sierra felt herself slurp on the spongy intruder in a wrestle of the lips, her eyes closed and her face a great shade of blushing red as she made out with the boy of her dreams.
Jack’s hands slid off her breasts and went down her lower back to grip her soft butt in his palms. Sierra mewed in his mouth and felt the urge to do more! She wanted no more of the foreplay for the moment, now she wanted the main course; Jack Darby. The influence of the pink energon radiating off of Jack prompted these urges but only after a certain level of pheromone arousal reached its peak.
A few class desk shoved to the side and Jack found himself on lying on his back on top of the teacher’s desk with Sierra sitting herself over his waist. She leaned down and succulently locked his lips with her own again but this time it was her tongue diving inside to taste his mouth.
Sierra’s hands hastily unbuckled the rest of his pants and trudged them down while she sucked in Jack’s lips, her left hand was now pushing his shirt up and feeling up his broad chest while doing it.
Letting go of her lip hold on Darby’s mouth Sierra arose and stood up on the desk, she sent a naughty wink down at Jack and then proceeded to tug down her skirt along with her boots.
Jack watched in awe as she stripped herself before him, soon enough her skirt was on the floor with her shoes leaving Sierra in only a tight white thong that she was now pulling down to her ankles.
Jack felt his meat twitch and stir when he gazed upon Sierra’s beautiful naked body, her neatly trimmed virgin pussy showed itself in plain sight before him thus causing him to restrain himself from reaching up to ravishing it.
Sierra noticed that look in his eyes and looked beneath her at the towering erection before internally deciding what she wanted to do.
“I think you’ll like this, Jack.” She purred and turned around to where her lovely ample butt was all he could see, he was about to protest until she lowered herself down and placed her pussy over his face.
“Sierra…” Jack stumbled before feeling the pink Energon suddenly kick his hormones into overdrive with Sierra’s mouth at the base of his cock.
With slurp her lips started lightly sucking on one of his balls while her left hand softly massaged the other. Jack strained his face at feeling this incredible sensation, but then he gathered his strength and grabbed her buttcheeks so he could push his face forward into her inner thigh area.
On contact her pale body shuddered as Jack began kissing all around on her labia eventually licking lightly on her pussy lips. His face dipped forward a bit to where his mouth was now giving her snatch the treatment of the century; following a trail of strong kisses around her sensitive area Jack also favored her carnal opening with his tongue sliding in and licking in rotation as best he can.
This caused Sierra no end of pleasurable torment, her body thrashed around a little which made her remove her mouth from Jack’s genitals because her head tossed around in orgasmic reflex. She didn’t cum just yet, but she was damn near close now.
Her rear bounced carefully atop Jack’s head as he continued eating out her fleshy treasure, Sierra kept herself busy by now balancing herself so she could easily place her mouth at the tip of Jack’s sausage. She wasn’t going to take it little bylittle and instead she began lowering her mouth on it letting more of the hardened flesh slide into her mouth/throat.
‘Hooo wow!!’ Jack mentally exclaimed as Sierra continued lowering her head down into his lap with his manhood sheathed deep into her mouth. The slimy flesh of her inner throat enveloped his cock completely causing him to restrain himself from grinding his hips against her face.
The redhead’s eyes ridden with lust when it dawned on her that they went this far already and planned to go further, she knew this was meant to be and knew at the end of this day she would be left in the happiest mood. Bracing it all she began withdrawing her head a bit before sliding it back down to swallow in more of Jack’s manhood, he moaned audibly and gripped her buttcheeks harder so he could repay the effort she was putting.
Jack dove right back in and hungrily ravished her snatch by rapidly yet accurately licking her most sensitive spots. Her nibbled on her clit and occasionally sucked on it, his lips kissed all-round the area before his tongue dove past her folds to whip around inside her pussy.
“Oooaah! Jack!!” Sierra
It took only a few moments of the two tasting each other to bring them off without fuss; Sierra clenched her thighs on Jack’s head with her pussy on his lips gushing in climax while Jack’s cock started shooting globs of seed into her mouth down her throat. Sierra held her head firmly on his hips until his length finished delivering its semen payload into her mouth.
Raising her head up before the substance could flow down her throat she took one last look at Jack and made sure he was watching when her mouth opened up to show a slightly dripping pool of sperm before closing it to swallow. Jack instantly felt his member regain some of its solidity when he witnessed the girl audibly gulp down his gooey substance.
“Oh you are incredible.” Jack said in awe before Sierra winked and turned herself around on his torso to face him. She leaned forward and cupped his face in her right hand with a naughty look in her green eyes.
“If you liked that then you’ll love this, Jack.” She whispered seductively and moved back so she could hover her hips over his now ready manhood that was standing attention. He was up for round two the moment he watched her swallow down, he may have needed more time otherwise, but this girl was totally worth it.
Her glistening folds were barely scraping the tip until Sierra gradually started pushing her hips down letting Jack’s cock dive deep into her opening. Half-way to the middle of his shaft she stopped when she felt her hymen touch the hard fleshy tool, with one last look to Jack she held both of his hands and dropped her hips all the way against his.
“Aah!” Sierra bit her bottom lip and clenched her eyes tightly as a newfound pain was being felt through her sensitive area, Jack never let go of her hands while she trembled adjusting the pain. Soon her shaking stopped and she opened her eyes to look into his, with a tender smile she leaned forward to kiss his lips as she begun humping her hips back/forth on his.
Jack let himself get lost in the intimacy of the kiss and felt like he had touched paradise by knowing he was making love to the girl he always pined for. He didn’t care that the pink Energon that hit him might’ve played a certain role in this happening, he just wanted to enjoy being with this redheaded vixen. ‘Living the dream.’ He thought letting himself go with the flow.
His hands went up to cup her buttcheeks as she amorously rocked her hips faster. His dick was sheathed all the way inside her soft tight pussy and now he was thrusting himself against her to increase the intensity.
Sierra’s head tilted back in response, feeling Jack’s length thrusting itself into her inner most private place. The feeling was exhilarating and made her whole body felt like it was on fire, in a good way.
Jack’s hips continued humping upward into her fleshy pocket automatically while squeezing her ample butt in his palms. Sierra’s back arched raising her upper body to where the boy could clearly see her breasts bouncing before his face. Her hands planted themselves against his chest as she rode him cowgirl style, his length repeatedly and slickly slid itself into her pussy energetically while she humped her hips on him.
The desk they were lying on was creaking as Sierra rode him, Jack removed one of his hands and placed it on her right tit to cup and fondle the ample mound in a further attempt to excite her. Obviously it worked since Sierra was audibly moaning her satisfaction which also caused her to rock her hips even harder.
“Ooaah! Oohh J-Jack..!!” She hollered out and arched her back when she felt her pussy clench and convulse with Jack’s dick all the way inside.
Jack in turn yelled her name and felt his hips thrust forward rapidly several times in response to feeling Sierra’s pussy muscles put the squeeze on his meat. His prick started coating the insides of Sierra’s youthful womb with globs of seed that soon filled her to the brim. Some of the white cream seeped out of her opening shortly after when the lithe redheaded girl slumped comfortably against a smiling Jack.
Both were sweaty and breathing a bit hard, not to mention mostly nude with the exception of Jack’s trousers dangling from his ankles.
Sierra had a dreamy look on her face as she nustled her head against his broad chest, soon she rose herself up and kiss him tenderly on the lips in a romance of sexual aftermath.
When she gently let go Jack looked confidently in her blushing face. “You know this will change things between us, right? Assuming you want to be my-“
“Girlfriend? Of course I do!” Sierra piped happily and wrapped her lovely arms around his neck like she belonged there.
‘Girlfriend…Sierra’s my girlfriend!’ Jack mentally cheered feeling as though he oculd die tomorrow and still be radiating life-fulfilled happiness.
“Guess this also means you’ll want to come riding my motorcycle with me afterschool more, huh?”
Sierra smiled wryly. “It won’t be the motorcycle I’ll want to be riding.” She said naughtily causing Jack to tense up with arousal and smile.
Meanwhile just outside the classroom reeking of sex Miko Nakadai stood looking at the window with an appalled and heated face.
“So that’s why he didn’t show up at base after school!” She said to herself heatedly. She was irritated Jack didn’t arrive yet because she wanted more ‘sex time’ as she called it, but now things have taken a twisted turn in her case. Miko crossed her arms in a puff and practically stomped away from the building. She didn’t know why she was feeling jealous and angry since she initially just wanted a ‘sex friend’ type deal with Jack, but after witnessing the raunchy intercourse between ‘loverboy’ and ‘cheer captain’ Miko thought otherwise. ‘Stupid Jack, it’s not like I like you or anything.’ She thought trying to convince herself.
But she looked back at the window as she walked away looking forlorn. Maybe she was interested in more than that, suddenly a daring expression came across her features as she smiled determinedly. ‘Okay, red, it’s on!’
