Pulling Favors Ch. 01

"It's surprising that it can stay so hard while so big," she murmured.

"Sometimes it is a challenge, but that's how much you've turned me on here," he released her hand to continue moving independently.

"Really, this much? I didn't think I was your type. I just got a little good at using my tongue."

"I get all sorts these days, but you have an appeal that goes beyond a nice pair of tits."

"Like what?"

"You're so much feistier than the others, much more inquisi6."

"Inquisitive how, exactly?"

"Plenty of girls will simply grab my dick, but I can tell you're studying it even now with how you move your fingers."

Mokuba stopped talking so that she could refocus on what she had continued to knead him almost subconsciously in her palm. Rebecca remained at a loss for what to say, think, or do, but that only amplified the tension between them as Mokuba's excitement skyrocketed through the gradual breaking of her prim and proper facade. The entire situation was unlike anything she had ever imagined in her life, yet nowhere in her did she feel truly bothered by it. Her demeanor was primarily one of patience and even some curiosity as he said. While she had been trying to take the lead before, Rebecca was content to now go with the flow to feel out where it was going to lead. The composure she now demonstrated while working her hand along his shaft put Mokuba in position to now be the one impressed with her. Even as the boy himself believed he was as hard as he could get, he could feel himself somehow continuing to expand, lengthen, and widen, and Rebecca could certainly see how he stretched further out towards her.

"Unbelievable, you're still getting bigger..." she clearly observed.

"So how's that for a wooden horse?" he growled.

"How much larger can you get?

"Don't know. I'm still in something of a growth spurt?" he teased, "Weren't you supposed to be the one to find out?

"Yeah, I really want to." she couldn't help but admit.

"To be honest, you're the first person to have me feeling quite like this. It's so hard it almost hurts, yet I'm so fired up, that I don't want it to stop."

"What do you mean?" she embraced her dirty curiosity more openly.

"I love the stern way you're staring at it right now," Mokuba looked into her eyes through her glasses while they remained trained on his dick, "Even after all that trouble, you somehow really do want to see me get bigger, and it makes me want show you how much more I still can grow."

"It's certainly a sight to behold," Rebecca smiled at how his shaft rose just a bit more through her fingers, "But I'm getting a tad impatient here. No matter how sexy you find me, you've got to stop at some point here."

"I never knew I was even capable of getting this excited before you came along," he confessed with another slight swell in girth, "I can't remember ever managing to get this hard on my own. I'd love to see what number comes out with you measuring it now."

Rebecca nodded more confidently than before and started to knead his member in ways aimed at drawing out any latent energy dwelling within. Making full strokes from head to base had it get a little longer with each completed motion. Kneading the softer areas would bring about a thickening that would pry back at her fingers. It took so much out of his racing heart to support it that Mokuba wondered if he'd end up passing out, but, at that point, Rebecca had settled herself in enough to work up the nerve to stick out her lips and plant a kiss squarely on the glans. This prompted all that he had left of his adolescence to come rushing out all at once to bolster his manhood to a dimension on par with the very best he had ever checked out on an adult video. He could only hope their still youthful bodies would be able to handle it.

"I would've arranged for a more proper scientific measurement if I knew I'd be running into something like this. Even so I can safely say that it's certainly no less than nine and a half inches long and six and three quarters around now," she analyzed him with a casual run with the measuring tape from earlier, "A dick overqualified for even the internet."

"Aw man," he was now the one left stunned, "Guys in my position typically have to pay up for sex, but I might be at the point where people would pay me for a go at this dick."

"Now, I think It's more than safe to say that my hands won't be enough."

"Yeah, I know it's a lot to ask you to take all the way but would you at least put your lips around the top," he was surprisingly considerate.

"Alright," she licked her lips and went in on him much more well prepared than before.

What she struggled with earlier was out of the question now but she was still able to do what was absolutely necessary and get the glands along with the upper portion of the shaft into her mouth for her to run her tongue along the underside. The spike in sensitivity that accompanied this level of arousal was made immediately apparent like how even a basic look could elicit a shudder from him. The flavor obtained a fresh zest that she had never spotted before or at the very least never properly appreciated. The movements of her tongue that were designed to hit him where he would feel blessed we're now aimed at sampling and savoring the new taste in greater detail. She soon wound up taking the head out of her mouth so that she could run her tongue along the entirety of his member.

"Oh fuck, Rebecca," he shuddered as she went at him like an ice cream cone, "When did you find it in you to do it like that?"

"If I'm the only one who can make you this big then I have to be the one to see what you can really do when you're fully aroused," she squeezed the top and licked the bottom, "You did say I was the only one, right?"

"Yeah," he somehow still felt the urge to grow even more excited and hardened in her grip to a nigh impervious degree, " I couldn't even deal with this on my own anymore. Please, I beg you. Don't think about stopping."

"As long as you give me my turn later to do my own study on this beast," she offered, taking some time to massage his balls that had gone neglected before now.

The rush of energy emanating from his burgeoning manhood combining together with their natural youthful exuberance forced Mokuba to fall all the way back on the bench. His neck and back arch as his head turned upward to release a groan into the air. Rebecca lifted her head to place his glands into her lips once more with both hands tenderizing as much of his meat as they could. By now, she had already had some of his pre-cum leak onto her face and hair, and now had it pooling on her tongue. Now she was handling him more like an ice pop, working hard to squeeze out his succulent juice. Working up the courage to go from a third to a half of him wound up being the final ingredient she needed to trigger his eruption which had increased in virility and volume in direct proportion to his member before. The spurts she was accustomed to now came out in full-on streams far too turbulent for her to take in her mouth. She pulled off before her mouth could overflow completely but pumped her hands all the way through as his excessive release leapt out into the air and rained down on her from above, making its way all over her hair, face, and back. It was a climax that both would remember unlike any they had seen before it.

"How's that, Mokuba?" Rebecca was just as amazed with him for what he just did as she was with herself for causing it.

"Money can't buy something like that," he sat up, still short of breath.

"But it did buy me my new laptop which I'm still thankful for," she reminded him.

"Of course, of course," he gradually composed himself until taking a good look at the girl before him coated in his essence, "Oh, wow..."

"What?"

"You might be the sexiest thing I've ever seen right now. My cum really got all over."

"Ah shit," Rebecca never realized just how extensively he had coated her with his seed, "Even my glasses."

Seeing her delicately pull out a cloth to wipe his splooge from her lenses that had already fogged up from the steam was the final straw for him. All of his arousal that had dissipated in his release came flooding right back. His manhood shot back to life as if nothing in the last few minutes that even happened at all only now with an even more urgent need coursing through it.

"Rebecca..." Mokuba sighed just loud enough for her to hear.

"Yeah?" she turned back to him only to get quite the startle when she spotted his member still standing as tall as ever.

"I need you," he took another deep breath.

"I can see that..." she laughed awkwardly at his erection, "But I already held up my end of the deal."

"I know but that was just a favor because I helped you before. This time I truly need you," he emphasized to which she understood but was unsure of how to proceed.

"What? So I need to do that all again?"

"No, that won't be enough. After seeing what I did on the outside, I need to see what I can do on the inside."

"You mean... you want to be in me?"

"Are you a virgin?"

"No, I did it once with a guy I dated briefly, with a condom, and a lot less meat than you've got on you."

"Please?"

"I don't know if I can. I can't conceive that I would be able to after all that it took just to do it with my hands and mouth."

"But you still want to at least try and see if you can do it? Right?"

She couldn't deny that the challenge was an enticing one. If could take that then what would there be that she couldn't take? What would it feel like to be spread open that far and reached into that deeply? All of a sudden, the seat in his lap was starting to look more and more comfortable. Before she realized it, her own juices were trickling out of her skirt and onto her thigh, causing Mokuba's erection to twitch in delight when he noticed it as well.

"I get to be on top though," she set her final terms with the horny teen, "I won't be having you tear me in two with that thing.

"No problem, do it however you like," he accepted.

Loosening her own body towel was the only bit of preparing that Rebecca still needed to do. While initially bashful towards exposting her C-cup breasts and petite waist, nothing else she felt now compared with the daunting task of taking his beast into her womanhood. She stood from her spot and moved to where she was facing him with his member pointing right up into her, placing her hands on his shoulders for her final bit of mental preparation.

"Damn, I can't believe I'm doing this," she muttered before finally letting her hips begin to drop.

Her hand reached down to hold Mokuba's member upright and he watched with wonder as she brought it up to her the moist lips of her pussy. By no means was it their first time, but it might as well have been with how much stretching it took just to get the head in. Getting the first few inches of his swollen, rock-hard, and substantial shaft inside created the image in her mind of a large cucumber penetrating her womanhood.

"Oh God, I really can't believe I'm doing this," Rebecca's voice went up an octave once she got past the quarter mark of his manhood.

"Take it easy. You're doing fine," Mokuba encouraged her while mesmerized by the way his member pried open her vagina inch by inch.

"Mmmm, so fucking big, so fucking big..." she bit her lip and repeated while she continued her way downwards once she took in the first half.

Her body almost did finally give out when she got to the last two inches, but Mokuba's surprisingly thoughtful arms reached around her to support her for the final stretch as she fully planted herself onto his rod and into his lap. Even after amazingly taking in all he had, the feeling of such a behemoth making itself at home within her took a good deal of time and several deep breaths for her to accustom herself to. The new sensation of his flesh being directly bonded with hers was a lot for Mokuba's mind to adjust to as well.

"Oh... shit... Mokuba... It... It's like..." she eked out between pants.

"Yeah, it's something else," he kept his hands firmly on her back but pulled her a little bit closer.

"It's... It's... Ooooooh" one single tremendous shudder rushing through her body seemed to refresh her ability to speak in complete sentences, "It's almost beyond belief..."

"Yeah, I didn't think it'd be like this either," he agreed with a glance into her eyes.

"It's just so... gargantuan," she spoke more closely into his ear, "I never fathomed that I would ever have this much cock in me all at once."

"And I never imagined you would take it all at once," he gently laughed back at her.

"Oh Mokuba, I don't even know what to think right now," she grabbed onto him as he maintained his hold on her, "It's stretching apart my womanhood so thoroughly that my entire body feels like it's being filled by it. Every inch feels so monstrous, aching to tear me apart completely, and yet, somehow, it actually feels kind of nice."

"Really?"

"It's crazy, I know, but there's something oddly fulfilling about giving all I have to this mammoth member of yours. It hurt a bit at first, but after a certain point it simply overcame me just what an amazing thing this is to have in me."

"Well, you have me feeling pretty nice too. I mean, it might as well be my first time right now," Mokuba confessed.

"Yeah, mine too," Rebecca agreed.

"Yeah but not just that. I was thinking that it's also been a long time since I felt like I had enough room down there," Mokuba clarified.

"Oh?"

"It's not easy. I mean it's fun to gloat about, but my pants have only been feeling more and more restrictive and I always ended up forcing it so much with the other girls I dated. This is the first time since these growth spurts kicked in that I really feel comfortable, you know, like I have enough space to just... let it out," he confessed.

"Ooooh," she felt herself become even more at ease with him, "Well, it's so rigid that it's kind of just doing what it wants in there, but that hardness feels really good too."

"And your pussy is super soft, warm, and mushy. Slipping into it feels so natural for me," he even started to blush, "It's great. Thanks, Rebecca."

Even as deeply connected as they were, for some reason a kiss still felt awkward for such an informal relationship, but both found a hug more than appropriate for the moment. The intimate exchange of thoughts inspired Rebecca to make her first motions since reaching the base of his shaft. They were only light rocks of her hips but each tiny plunge onto his manhood offered a more electrifying spark than the one before. Its shape was more deeply ingrained in her mind each time his head brushed against her cervix with her awareness of his more minute features increasing in clarity aided by the slick coating of her juices tenderly applied along his length by the lips of her furtherly aroused vagina. His hands seemed to make their way lower down her back in proportion to the rising heat between them. So much so that she undid and fully discarded the towel that still hung loosely over her shoulders.

Oh fuck, you're really taking the whole thing," Mokuba let out a gasp, "I've never had it being squeezed all at once like this before."

"You certainly aren't making it easy for me," she huffed, "Always using a rubber thoroughly failed to do justice to this incredible texture. That fat head of yours is scraping me so much that going any faster might make me lose it."

"Then at least let me feel a little more of you," he used his hands resting on her waist to guide her into longer strokes.

Wait, wait, shit!" the sudden change in his motions introduced more new sensations into her mind than she was ready to handle at once, "Oh fuck, Mokuba!"

"How's that?" he was now going in and out about a third of the way with his member.

With her mental faculties momentarily disrupted, her body resorted to making its more natural responses to him. Her vaginal walls began tightening on his erection in random, frantic intervals. It appeared to be a way of indicating he was too much for her yet only served to invite her to go even farther. He mustered all of his self-control to keep himself from going any harder before she was ready again, but all of that pent-up desire only made its way straight into his member, solidifying and bloating it into a distinctly erotic new shape for her womanhood to contend with which it did with a fierce climax. The boy paused to experience the waves of orgasm crashing over her, both in how he could see her body quivered all over and he could feel it all coming down on his manhood. It was all a shock like he had never known.

"Did you just... cum?" he murmured to stunned surprise.

"Yeah, I think so," Rebecca had slumped back but pulled herself back up with the help of his shoulders

"Wow, that's actually a bit of a first for me, having a girl cum right on my dick."

"Hm?" still re-gathering her strength.

"I've always been too much for them before I finish, but you really did it."

"Uh-huh, I guess I did," she confirmed.

"You're pretty amazing, Rebecca," he gave her a refreshed grin. His erection suddenly had a new sense of pride emanating from it that had her eyes springing back to life.

"Damn, how does that body of yours have a heart strong enough to keep such an enormous dick this hard and have it throbbing so much all over? It's like a jackhammer in my belly," Rebecca was taken aback by his renewed and even further enhanced vigor, so much so that she blurted, "How am I ever supposed to go back to my vibrator?!"

"So, I'm better than a vibrator?" Mokuba seized on her gaffe

"So much better!" she didn't even attempt to deny it

"Thanks, you're a lot better than any toy too," he cradled her, "I outgrew my fleshlight too, you know. Couldn't even get in halfway before."

"I think I can manage at least that much for you since I came first."

"Sounds like we have a new arrangement then," he announced.

"Huh?"

"I don't mind letting you have some fun with this cock of mine if you ever happen to be feeling frisky. This pussy of yours will make it more than worth it on my end."

"Well, I guess I probably won't ever be casually finding a subject like this on the street or in a science book," Rebecca noted the outline of his penis within her still extending upwards and past her navel, "I suppose I still have a lot I could stand to learn here."

"So? Still friends?"

"Just a little more than, actually," she was finally primed to begin moving again.

Rebecca promptly re-assumed her prior pace without his assistance. There was still some visible strain to it with every ounce of excitement from his manhood running through her each time she went up and back down to the base, but she was able to remain smooth and consistent with her motions. Her next challenge came when Mokuba began to add in his own movements. He was past the point where he could keep his hips completely still in his seat and the continued pressure of her vaginal walls bearing down on his erection was soon accompanied by some increasingly ferocious twitching from him.

"It really is like a wild animal," she moaned, "Rampaging against all of my most sensitive areas. Fuck, I love it."

"Because you don't let up even when I'm about to explode. If I made you cum once, I have no qualms about making you cum twice."

"Not until you finally cum."

"Even if it's inside you?"

"It'll be our new contract with each other."

"Seems like a binding agreement to me."

In accordance with her promise just earlier, Rebecca pushed herself to get her hips humping along a solid half of his length, maybe even a bit more. Her canal opened itself to accept a ravaging more intense than ever. Now, the bulbous glans she had become enamored with was alternating strikes against her G-spot and cervix. Each time she bottomed out had a healthy thump to it with his lust testicles brushing against her when he gently bucked his own hips in rhythm with hers. His hands drifted from her waist to her hips to provide a little bit of lateral movement that he was yearning for. Sporadically, he would feel a tightening around his base that would creep its way up her walls and along his shaft, concluding with a tense squeeze of his head at the end of her passage. In all, it had been way, way too long since Mokuba could revel in being enveloped like this, and it was an even more spectacular sensation than any he could ever remember.
