Hot and Sweaty Smacdown:

Penny shuffled her feet. She looked at the floor. She tried to ignore the whispers.

She hated riding the bus. Being trapped in a metal cuboid with a bunch of strangers wasn't her idea of a good time, but with the dire state of her finances, she could hardly afford a car, and she needed to get to this wrestling tryout if she ever wanted to change that. But... god fucking damnit, why had she decided to go in the gym gear?!

A pair of pastel pink yoga pants hugged her sizeable rear, showing off the shape of her legs and ass, not to mention a petite bulge on her crotch, while the sports bra she'd bought appeared to be horribly undersized, exposing both her cleavage and soft midriff to anyone who cared to look. And since the bus was standing room only, it was all too easy for people who wanted to get an eyeful to take advantage of the situation...

Of course, just as many people disapproved of her choice of clothing as well. Chief among them seemed to be an old lady sat near the front of the bus, who would intermittently catch Penny's eye and then look away with a disgusted grunt. Penny couldn't help but feel ashamed given the circumstances, she'd never done anything like this before and she was starting to wonder if that might have been for the best...

As Penny thought this, she heard a strange noise from behind her, heavy breathing, and... were those... camera snaps?

She turned, and was greeted by a sight that almost made her recoil. One of her old classmates from university, a greasy, sweaty geek with thick glasses and a bowl cut, wearing a long black leather coat and a similarly unfashionable pair of loose cargo shorts. He was holding his phone out in his left hand, the camera pointed squarely at her plump backside. And his right hand was... oh god. Penny shuddered when she realised it was under his waistband, working up and down, slowly but deliberately.

He caught her eye, and looked up, clearly able to see her disgusted expression. Rather than freaking out, or making excuses, he merely gave her a lewd grin.

"Hey there Penny, it's been a while," he groaned, hand still working, gaze returning to her ass.

"You look good in that workout gear... you get a gym membership or something? Ooh, or are you doing yoga? Can I watch you?" he asked, licking his lips, and Penny felt something in her stomach. But rather than the churning, repulsed reaction she'd expected, she felt... excited. Oh god. She stood, frozen in place, trying to make sense of her feelings. This guy was taking pictures of her ass. While masturbating. In a public area. She was positive she shouldn't feel excited, and that she should in fact be slapping him and demanding he delete all those pictures. In fact, she was going to do exactly that. She looked over again. She heard the constant clicking of the phone continue, watched the slow motion of his hand as it pumped up and down, in time with his panting... and then he glanced up, looked her in the eye, and let out a long, drawn out moan.

And almost without thinking, she stuck her butt out towards him. Fuck. Fuck. What the fuck was she doing?

"Ooh, looks like someone's getting into this, aren't they?" he cooed, snapping a few more pictures, and moving his hand just a little bit faster. Penny couldn't bring herself to reply, instead choosing to bite her lip while trying to ignore the feeling of blood rushing into her dick.

"Could you wiggle your fat ass just a bit?" he panted, while his phone gave a small beep to indicate he'd switched it to video mode.

Penny wanted to hesitate. She wanted to stop, consider what was happening here, and then come to the entirely logical solution that this was stupid, dangerous, and a situation she should extract herself from immediately. She may even have done that, if what he'd said hadn't caused her hard little dick to pulse gently against the inside of her pants. Again, rational thought deserted her, and she nodded her head just a fraction, before starting to shake her hips, causing her rump to jiggle and sway in front of the man's slackening jaw. His hand was moving even faster, as was his breathing, and Penny began to feel herself panting as well, blushing as she helped this practical stranger masturbate while ogling her.

As their voices reached a fever pitch, Penny caught the eye of the old woman again. She looked completely and utterly disgusted with what was happening. Clearly she could see her partner in crime behind her as well. Penny almost felt ashamed again, but this time the feeling was drowned out by a perverse enjoyment at the woman's discomfort. Instead of looking down at the ground, she locked eyes with the woman, and grabbed her own hardening cock through her yoga pants with her left hand, while using the right to raise a middle finger at her. She stuck out her tongue as well, for good measure. It had the desired effect, as the old woman's wrinkled face quickly distorted into a picture of shock and outrage, as the intended message sunk in.

'I'm hot, and you're not. Deal with it, hag.'

As Penny did this, she heard a final monumental groan from behind her, and turned around to see a spreading stain in her new friend's shorts. People around her recoiled in horror, many yelling at him as his eyes glazed over, among other things. At the same time, the bus pulled to a stop, and Penny glanced out the window. One stop short of where she had to be, but it was probably best she got out of here.

In the ensuing confusion, she slipped off the bus, and bolted straight for a nearby alley, where she stood for a few minutes, trying to get her bearings. Fuck. Why did she do that? She wasn't that sort of girl, she didn't like doing things in public... was she?

Her dick twitched, and she grimaced. She tried not to think about it as she quickly rearranged her pants, hiding her cock by holding it in place with her waistband, before making the slightly awkward walk the rest of the way to South Street.
