"Yeah, just what I thought. That's a delightful ass you've got there." Could anyone else in the carriage see this? See what she was doing to him? He was paranoid, but he had to think that probably they couldn't. Through the forest of heads and limbs they must be almost invisible at this end of the carriage. Christ, she could do whatever she wanted to him! "You used to do sports right?" Carl didn't answer, didn't know whether he should. "When I ask you a question just nod or shake your head a little to answer, ok?" Carl nodded. In the window he tried to catch the reflection of the girl's face behind him, but there was only a silhouette, a curl of hair.
She shifted her weight slightly, her tits still hard against his back, her chin now on his shoulder for a second and then her right hand on his right cheek, giving it the same rough mauling that she had given the left one. His balls bobbed between his legs; he was getting harder and harder. Was she trying to get him hard so that when he got off he'd be humiliated - sporting a massive boner through his suit pants?
"A cute ass, and you're not bad looking either," the predatory purr of a big cat, sizing up it's meal, "You're letting yourself go a little though, and those glasses and that hair? Terrible idea. Your suit is a horrible fit too, look at all this loose fabric," the girl yanked at the back of his pants, pulling them away from his ass. Then, just as quickly, she brought her hand back again and jammed the bunched fabric between his cheeks with a pointed finger.
Carl couldn't help jumping this time. Not only was she jabbing at his ass in a very... intrusive way, but bunching the cloth of his pants up like that dragged his balls back under his body and bent his thickening cock in a way that turned him on even more. She released him after a moment, but he knew his ordeal was far from over.
"But, y'know..." he wanted to turn her head and tell her to stop, but he couldn't move his neck, let alone his tongue. In a way this was a wet dream come true (in fact, he wasn't sure he wasn't still dreaming all this still) but Carl wasn't an adventurous guy - he'd rather his fantasies stayed in his head and his daily life continued in as seemly a way as possible. The girl's left hand was back, gently squeezing and stimulating his left cheek while her right hand, as he had feared it would, was slipping around his waist. "Y'know, girls are interested in more than butts."
Oh God, oh God, oh God. There it went, her clever little hand snaking it's way over his hip, touching his belt and then slipping into his suit pocket. She left his ass alone now, pushing herself against him full length again and bringing her other hand around to rest on his chest. He was painfully aware of her hand as it slipped, centimetre by centimetre over the trembling flesh of his thigh. And his traitorous prick, thickening more, trapped by his boxers but rising up to meet her.
He looked into the reflection in front of him, over his shoulder and back into the train. There were so many people, nothing but people, and none of them were noticing this! He could call for help, he could! But that would be... ludicrous! This girl is molesting me? Who would believe him? And besides, there was some part of him that was... accepting this, allowing it, wanting it.
"Good boy," the girl purred, resting her chin on his shoulder to wrap her arms around him, "just let me play with you a little. I promise I won't break anything!" She seemed to find that incredibly amusing, her cool, low voice breaking into a breathy giggle. The sound of the train, a little conversation, the tinny ring of headphones - they were all drowning out her voice to everyone except him.
Her hand explored his pocket, pushing down and across and sure enough, finding his fattening tool took her no time at all. And as she felt its shape, exploring it through his pocket and his underwear with the same commanding grip she had used on his ass, they both couldn't help but gasp.
"Wait..." the word was on Carl's lips, but he barely pushed it out. He didn't see how he had any hope of controlling this situation anymore. His eyes glanced frantically this way and that - could anyone see this? The old guy next to him? He seemed to be asleep, leaning against the other side of the doorframe. The girl in the next carriage? Still lost in her book, still cute as anything.
"Oh there it is!" there was a low chuckle that Carl only felt, through her chest into his, "And you don't disappoint there either!" Her fingers traced his shape and he felt her probing, coaxing his cock into a more and more swollen, turgid state. "A nice thick, curving shaft; a hard, hot, bulging head," every word that dropped from her pouting lips stoked his fire making him harder and harder. She was narrating her progress as her fingers dove down further. "And two big, heavy balls, just full of hot, sloppy come. Am I right?" Carl couldn't move. "Yes or no?" her voice had an edge, Carl knew he had to answer, he nodded sharply, blushing even harder to find that he had little control over his body now.
Her hand moved back from his balls to his shaft and started rubbing it now, half jerking him through two layers of fabric. Carl felt his heart in his chest, feeling bigger, beating harder. He breathed in through his nose, out through his mouth, desperately willing himself not to release the groan of pleasure that wanted out of his lungs. His prick was so hard, and though his boxers were pretty tight it was out away from his thigh now, proud and demanding more attention. The girl - his attacker - seemed happy to oblige.
"Do you watch porn Mister?" she continued, pulling on his foreskin and dragging it down forcefully. He felt moisture and knew that his pre-cum was staining his underwear under her clever ministrations. He nodded though, scared not to answer. Her hand went up and down again, tugging on him maddeningly. "Do you have a girlfriend?" he paused, he wasn't sure why, before shaking his head, "Jerk off every day?" Again he paused, these questions were so personal, he was giving parts of himself away so cheaply. But then... he was the prey here, and he found it so easy now to just answer her questions and not put up a fight. He nodded. "Jerk off this morning?" he shook his head. He hadn't come last night either, he had been planning to squeeze one out tonight to a new DVD he had ordered. God, she could probably imagine even that - she had his number now.
She moved herself more to the right, so that she could reach around him more easily and thrust her arm even further into his pocket. He felt her tits squeezing and sliding sideways across his back a couple of inches and bit his lip. Oh God, he was getting dizzy; and while his brain was still stumbling and lurching around like a drunkard, his body knew exactly what it was doing - getting aroused and ready to fuck.
She could really curl her fingers around his solid shaft now, grabbing it through his clothes and squeezing tight. She slid her hand all the way up to his hot, bulging head and started to massage the back of it with her thumb. Carl managed to turn his groan into a cough as his prick jerked and twitched in her hand. It felt so good - if she wanted to make him come, to make him shoot his pathetic load and soil his underwear, there was nothing he could do to stop her. He had hands too, but they were useless, one tucked into his left pocket, the other hanging down dumbly. He couldn't use them to stop her, he wasn't strong enough, mentally.
"Good," her chin on his shoulder still, her words hot, melting into his ears, "I'll be the one making you come today, ok? Although you'll probably need to jerk off again once you get to work, won't you?" Carl swallowed, not realising she needed an answer. She squeezed his dick sharply and he flinched, nodding quickly afterwards. "You'll be sitting at your desk thinking about what happened to you on the train this morning, and your fat prick will get all hard again, won't it?" He nodded. "And then you'll have to get up, bent over so no one can see your bulging pants, and run to the bathroom to jerk your hot spunk out - thinking of me - won't you?" Carl squeezed his eyes shut, praying for a little control over the situation, but he nodded obediently again.
She started jerking him then. Before, her hand had been moving so slowly, just rubbing and massaging his thick shaft and the come-slick head of his member through the cloth of his garments. But now it gripped him and started to pump, pulling his sensitive foreskin up and then down, squeezing him tightly as it gripped the tip, and pulling down - almost too hard - as it got to the root. Carl started to breathe harder, trying to focus himself and keep some semblance of control, but the girl wouldn't shut up.
"Don't say anything, by the way. Don't even think about trying to get away. And don't try to deny you're enjoying this." Her voice was so calm, so cool. She seemed to have no fear of being caught, and her absolute confidence did calm Carl down a little. "Oh! You're getting really turned on aren't you? You're little dick is all twitchy and jumpy in my hand!" her light giggle was hypnotic, lulling him dangerously. He felt sparks in his fingers and toes, a pressure, a tightness in his balls.
