With proper motivation, anything is possible

Ruby glanced over to Sweet Pea only to see him lazily scrolling through something on his phone. They were in his trailer, for once, studying. Or, she was. Ruby groaned and pushed herself up from the old couch, getting the teen's attention.

"You done?" Sweet Pea asked, eyes returning to his phone. "Toni and Fangs want to hang out at the Wyrm, if you are."

"I am," he instantly perked up at that. "But, you aren't." The happiness left his eyes and Sweet Pea slumped back into his seat on the floor, head lolling back on the couch.

"Seriously, tater tot, I tried," he tried to slither out of studying. "But, I just don't have the concentration for it after sun sets." Ruby huffed, sitting criss-cross, her notebook in her lap.

"That's why I said we should do this straight after school." She pulled her book closer, ignoring the quick typing Sweet Pea was doing on his phone.

"Yeah, but I had a job to do with FP and Tall Boy." He grumbled back and she knew by his tone where their conversation was going. They always ended up squabbling about how, when and where they should study. Sweet Pea lobbied for no studying at all as if his life depended on it. And, Ruby, in turn, quarreled to get at least two hours of solid work in, in hopes of getting him to pass to junior year with her. She usually won, especially when she mentioned how she would probably be sitting in class next to some other boy if Sweet Pea was retaking his classes.

"That is why you can't go mess around with Toni and Fangs or procrastinate on your phone now," her tone held an edge to it. "It's study time." Sweet Pea looked at her with sparks of anger in his eyes, a familiar look, but usually not reserved for her.

"Study time was over two tests ago." He shot back.

"Alright, but you'll be missing out on something good if you decide to leave now." Ruby fired off without thinking.

"Like what, more unsolvable equations?" Sweet Pea sarcastically remarked. He had obviously been spending time with Jughead, judging by the improvement in that skill. "More re-dos because I got the wrong answer at the end?" Ruby's mind went into quick overdrive. She needed to keep him focused on the math. Interested in it. And, there was one thing which she could think of. Probably a bad idea, since they were alone in his trailer for the evening, but she didn't care. At that moment, all she wanted was for him to damnably focus and stop procrastinating and trying to slither away like the snake he was.

"Every time you get a problem right, I'll take off a piece of my clothing." She had apparently said the perfect thing to achieve her goal. Sweet Pea's eyes widened, phone falling onto his lap. He turned fully to her, now folding his legs in a criss-cross position to mirror her.

"You serious?" He gasped out, voice deep.

"As a heart attack." Ruby returned in a low tone. She was very glad that it was winter and that it was chilly inside Sweet Pea's trailer at that moment. If not, she would have been left naked too quickly. By the way Sweet Pea was looking at her, that was definitely his goal.

"Alright," he grabbed his phone and quickly typed something, the sound of a message going through ringing out. Then, he tossed it on the couch behind him. "Which problem do I do first?" Ruby looked over her notebook, finding a fairly easy one to get him going. She read it out and Sweet Pea wrote it down diligently, getting started on solving it. In a few minutes, with only one moment of head scratching involved, he eagerly smiled at her. "Two square root of three." He gulped, waiting. Ruby checked the result against hers, which she'd already gotten right.

"Correct," she confirmed and locked eyes with him. Sweet Pea was watching her with rapt attention. Ruby trailed her fingers up from the notebook in her lap, across her body and pushed her hair over her shoulders, not breaking their eye contact. His eyes were positively burning and he swallowed again. Ruby hooked her ring finger and pinky under each side of her red leather jacket, spreading the other ones wide, showing them off. She knew that he had a thing for her hands and was going to use it the best she could. Her chest moved forward, making Sweet Pea's eyes fly down to her breasts as she slowly slid the jacket off her shoulders, moving her head to the right to show off her neck. He wasn't breathing, she was certain of it. The jacket slid further down, her left arm twisting behind her to leave the sleeve, before going to the front to yank the clothing article in a quick motion from her right one. The jacket dropped to the floor with a soft sound.

"Fuck." Sweet Pea commented in a strangled gasp. Ruby held his heated gaze for a moment when it flew back from the discarded article of clothing to her. Then, she looked at her notebook. The next problem she gave him was a bit harder, but still rather simple. Sweet Pea shook his head, jotting it down with a trembling hand in his notebook.

The game continued, Ruby slowly giving a harder problem each time, while the biker got them all right. Maybe he was actually pretty good at math, she mused as she teased him with taking off her remaining sock. She'd lost her jacket, both boots, the comfortable flannel button up she'd stolen from his closet and now, both socks. Next, she had to choose either her pants or her shirt, leaving her in her underwear either way. So, she picked an equation she'd had trouble with next.

Sweet Pea took his time solving it. He erased a part of his work at some point, returning to the top. Then, he scratched his head and erased again. Ruby was almost giggling at that point, expecting a wrong answer to come, but she managed only to smile and hold down her chuckles. Sweet Pea looked positively tortured. His face was flushed and his hands were trembling badly. Ruby was willing to bet that they were as cold as ice like they usually were when she got him all bothered. He had cursed a few times on a number of equations when he'd gotten stuck. The latest one wasn't an exception. But, finally, he looked up, telling her the answer. She was surprised to find it correct in her notebook. And, she decided that she would break his winning streak right then and there.

"Good boy." Sweet Pea's eyes practically flew out of their sockets.

"Jesus, Ruby." He gasped out. She noticed the way he'd pressed the notebook to his lap with his large hands, waiting in anticipation for the next part of her show. Ruby slid from the couch, standing next to it. Her hands rose to her lower stomach, playing with the edge of her shirt.

"What will it be, Sweet Pea?" She asked devilishly. "Shirt or pants?" Ruby didn't think that he could look more tortured than a second ago. Apparently, she'd been wrong. His brow furrowed and his tongue darted out to wet his lips.

"Pants, please." He'd actually begged her to take off her pants. Ruby managed to mask her shock at the honest plea and mischievously pulled up the hem of her shirt a bit, fingers playing around the button of her dark jeans. Sweet Pea's eyes were glued on them and he wasn't breathing, much like during the other parts of her show.

"I don't think so," Ruby replied with a tilt of her head in a teasing tone. Sweet Pea's eyes went to hers, noticing the smirk on her face. But, soon enough, they went down again, as she started pulling the hem of her shirt further up, before dropping it completely. Ruby's hands went behind her back, sliding under her long-sleeved top. She unhooked her bra, ignoring the confused look on Sweet Pea's face and let go. Instantly, her breasts dropped a bit lower, which got him to groan once he realized what she had done. Ruby slid the straps of her bra off her arms skillfully under the sleeves and then pulled it out of her shirt, letting the lacy black piece of clothing hand there for a second, enjoying the way Sweet Pea's eyes couldn't leave it. Then, she dropped it over her jacket.

"Oh, fuck this." Sweet Pea tossed his notebook away and hopped to his feet, grabbing her hips and slamming their lips together in a heated kiss. Ruby's hands trailed up his strong arms and one tangled in his hair while the other hooked around his neck, pulling him even closer to her. She had, in all honesty, been surprised by his endurance. She's expected him to snap sometimes around the flannel hitting the floor. But, all thoughts of studying left her mind as his cold hands, like she had guessed, slid under her shirt and caressed her skin, going up.

That's all for now, folks! Stay tuned for Day 4 :D

I'd like to thank When I Make It Shine for following this story :D

Hope you enjoyed!

Bonus:

"Ruby, I swear, if you pick that book up, I'm going to smack you." The girl in question stopped inching her fingers towards the math book and let her arm fall limp against the side of the couch with a soft thud.

"Who knows, maybe I'll like it?" She pushed herself up on her elbows, her tired body still pressed against Sweet Pea's warm form because of his tight embrace on the couch. Ruby felt his groan at the teasing words rumble through his chest. He looked straight at her knowing smirk.

"You're evil, you know? A devil woman. A teasing devil woman." He dropped his head back on the armrest, staring at the ceiling of his trailer in an attempt to calm down. But, alas, image after image appeared in his mind. Sweet Pea liked to blame it on teenage hormones.

"So, what do I need to do in order to get you to finish revising for the test?" Ruby sighed, shifting so that she could lay her arms on Sweet Pea's chest and then place her chin on them. Her torso instantly became warmer from his body heat and his hands went up from Ruby's waist, rubbing gentle circles along her back. She didn't think that he was aware of doing that.

"Are you serious right now?" Sweet Pea asked, looking up at her again.

"Nothing too freaky." Ruby immediately added once she saw his growing grin.

"Okay," Sweet Pea moved to sit up, dislodging the girl gently from her comfortable cuddling spot. "It's not weird. Well, not too weird," Ruby groaned, but she couldn't resist the childish glee with which the hulking biker jumped around his trailer in his birthday suit, before sitting back down next to her. "Here." Sweet Pea handed her her lacy black bra and panties and waited.

"Okay." Ruby stood from the couch, very much aware of how his eyes were following her every move. She slipped on her panties and then hooked her bra in the front, then spun it around and tugged it up into its proper place. Sweet Pea seemed fascinated with every motion she made. However, the expression of childish glee didn't leave his face. "Now what? Am I supposed to meow and crawl over to you?" Sweet Pea and Ruby had already been down the weird road of oddly specific fantasies each of them had. Most of them, though, were his. And, the more comfortable they got with each other, the more erotic they got, leaving her feeling a bit out of her zone.

"Now, walk over there and put on my Serpent jacket. The winter, leather one." Sweet Pea sighed and leaned back on the couch, watching the underwear-clad girl expectantly.

"What? That's it? And you'll study when I do that?" Ruby asked in a disbelieving tone. She got an eager series of nods back. "Man, I was expecting you to ask for a strip tease or a lap dance or something." She shrugged and headed for the hooks next to the front door of his trailer slowly, swaying her hips and giving him an eyeful.

"Wait, a lap dance was on the table?" Sweet Pea repeated, eyes wide and mouth dry. Ruby shrugged and then pulled on the leather jacket as he'd instructed. It fell to the middle of her thighs and positively dwarfed her. But, the expression on his face was worth it. "Maybe next time," he gasped out. "Now, come here and help me finish this." But, no matter how hard Sweet Pea tried to focus on the math, he couldn't keep his eyes from going over her form all too often. She was his dream fantasy made reality, after all.

Now, I'm actually done xD I just couldn't resist Sweet Pea living out his fantasy here hahahaha
Let me know how you liked it :D
