"My butt?" Jenny asked, giving her brother an uncertain look over her shoulder. Of course she had expected him to oil in all of her naked skin, but it was the tone in his voice that suddenly made her a bit hesistant.
"Yeah, you don't want to get a burn, do you?" He quickly replied, trying to be casual about it while making sure his raging erection was out of sight of his sister's wondering eyes. "It's not that easy oiling your own bum, is it?"
"No, of course not... I just..." She started while moving her hand back to straighten the bottom of her bikini. It wasn't until then that she suddenly remembered just how little of her ass was actually covered by the tiny piece of garment, and a moments silence followed as she let her fingers run across her naked skin.
"You what...?" Jimmy eventually queried while again doing his best not to show how dissapointed he'd be if she told him no.
"Uh... Nothing really..." She told him, she too trying not to show her true feelings. She had never felt embarressed in front of her own big brother before, simply because he was familly and not some stupid guy who'd just try to get right into her panties. His obvious eagerness about getting his hands on her bared buttocks was therefore something completely new to her. "I mean... It's okay for me, I guess..."
"I just wanted to be sure!" He tried to assure her, again having a little trouble to keep the excitement out of his voice as he poured new oil onto his hands and set them to work a bit lower down his sister's thighs rather than going directly for those beautiful globes of temptaion in front of his eyes. "I mean... You've grown a bit since last time you let me oil you up like this..."
"Uh-huh..." She agreed, trying to relax as she felt his hands slide further up her thighs and eventually start kneading her firm little ass. It certainly wasn't an unpleasant experience to have her buttocks oiled in and massaged like that, and she couldn't help herself from wondering what it'd be like to have some real hunk of a guy doing the same thing to her.
Well, her brother actually was a real hunk of a guy, she had to admit to herself. What she actually meant, was that she'd like to have someone do it in a little less brother to sister kind of way. "Someone who'd really enjoy getting a good feel of my little ass." She thought to herself, giggling a little as more oil was carefully applied directly onto her naked buttocks and then firmly kneaded into her skin. "Yeah... Just like that... All the way up under the waistband, and then all the way down... Spreading my cheeks and letting those strong thumbs work their ways up and down my crack...!"
While his sister seemed to doze off under his kneading hands, Jimmy started wondering if he'd died and gone to heaven. His sister's tight little ass felt wonderful in his heavy palms, and once he had started kneading it he knew he'd not be able to stop until someone made him. Quickly running out of sun oil he grabbed the bottle and squeezed out a generous amount of it right onto his sisters skin, then continued rubbing it in while watching some of it dribble down the crack of her ass.
Several minutes must have passed while he just kept going, his movements becoming bolder and stronger in pace with his heart beating faster. His thumbs slid deep down the crack of his little sister's ass every time he rolled her buttocks in his palms, and each time he reached the small of her back he pulled the waistband of her bikini further up with him so that the tiny string eventually cut deep into her pussy to make the puffy and well shaved lips clearly visible to him.
Needless to say, his fat cock was now straining like never before against the inside of his swim trunks, threatening to rip a hole through their front. He desperately needed some kind of relief, but even in his current state he knew full well that there was limits that should not be broken, no matter how much he had allready been stretching them... |
