He stepped into the cubicle, shutting the door behind him, twisting the rotary lock so that the other side showed it as 'occupied'. Then, turning to face the receptacle in front of him, he unzipped, withdrawing his manhood and aiming it at the water. A few moments later, there was a soft tinkle as urination began, and he closed his eyes as the process played out.
The hand slipped around his mouth and nose first, cool fingertips appearing above both orifices, quickly stopping him from reacting to the sudden touch. A split-second later, he felt the warm presence of her body against his, hers pressing up against him from behind - he could feel the hotter, harder push of her two breasts in his shoulder blades, the warmth of her hips on his backside, the presence of her standing behind him, as tall as he was and every bit as alive. He froze, the sudden touch shocking him - in the meta-time in which the brain operates, he considered pulling away, shouting, thrusting his head back or perhaps spinning, still flowing member in his hand and all. But before he could decide on any one course of action, the second hand slithered over his hip and curled across the open edge of his fly, slipping around the base of his flaccid cock as her fingertips split apart, winding around him.
'Be quiet.' She breathed in his ear from point-blank range, her hushed, sultry voice warm and intense as it entered his head. 'Don't make too much noise. We wouldn't want anyone else to hear you.'
He nodded, aware of the implications behind responding to her after the command, making a rapid, fervent wiggle with his chin. Her hand remained over his mouth. 'Good boy.' She breathed again, and he huffed slightly, feeling his warm breath escaping past her fingers - not tight enough now to stop him from breathing through his nose, but close enough to pinch it off at a moment's notice, just far enough away to allow him some air. The lower of the two hands closed around him, and he could feel the stream petering out as he began to stiffen under her touch. He felt, rather than saw, her smirking, devilish grin, feeling the effect she was having on him and enjoying it immensely. '
Very,
good boy...' She added, her voice minute and yet deafening beside him.
Grunting slightly, he moved a little beneath her touch, his hips adjusting his stiffening cock in her grasp as her hand slipped around his base, closing so that she was holding him in her fist as he hardened. He glanced down long enough to see his helmet rising to attention before him, feeling the jerk of the hand over his mouth pulling him back up to stare into the tiled wall, breathing more heavily now. He felt the ire emanating from the woman pressed up behind him as she held him from looking, knew she didn't want him to watch - and the fingertips pressing into his mouth and nose closed in for a few moments, reinforcing that knowledge moments later. He sucked against her hand through his nose until she released it, knowing that further argument or disobedience would result in disappointment and punishment, both things his rapidly growing manhood did not want. For a while, he simply stood there, his own hand moving aside as hers took over the job of holding for him. He grew until he was fully erect, and felt her cool fingers return around his base in reward, her soft hand rapidly warming from the heat of his member.
He could feel her breathing, feel her breasts pressing against his back, her chest rising and falling as she inhaled and exhaled right up close to him. He knew she was standing right in close, feeling the warmth of her hips and legs all the way down his body, and a thrill ran through him as he pictured her there, as close as they could be, save only for if he was up inside her body proper. His cock throbbed slightly as arousal began to build inside him, and he felt the soft hand begin to move, ever so slightly, just gently pulling his skin upward as it departed from his navel. He bit his lip.
'Don't make a sound.' She told him as her hand slipped upwards, dragging his loose outer skin with it, slowly travelling up his length as her free hand remained over his mouth, silencing him physically. He nodded briefly, focusing on her chest, her heat, her touch. The hand rose higher, the edge of her thumb meeting the base of his helmet. He twitched again, and the hand pressed over it, squeezing the bell-shaped thickness of his tip ever so slightly more as her hand maintained the same consistent tightness.
'That's it.' She said in a whisper, her hand drawing his skin together as it drew over his helmet, her fist as high up as he was long now. 'Just let it happen. Let me make you feel good.' She did make him feel good - he felt incredible already. He had no idea how she had gotten in here, how she had snuck up on him, but fuck was he glad she had. His only just erected cock already yearned for more stimulation so that it could reach ejaculation, and his breathing was quickening in time with the pounding heart in his chest. He thought he could make out hers through those two soft, warm mounds behind him, and he pulsated again as he re-focused on them, knowing her bosom was right there, pressed between them both. The hand stretched his skin as it began to descend once more, and he sighed softly as it drew gently downwards, every tiny ripple in his shape pressing differently into her skin and massaging him through her hand's motions as she went.
Slowly, the fist sped up. The first few pumps barely moved, taking long, dragging seconds to rise along his length and even longer to return, but now it had begun to quicken, squeezing ever so slightly tighter as it moved faster. He grunted as her hand pulled his skin tight at his base and once again the hand closed over his mouth, her other pausing where it was in punishment. When he had ridden out the teasing wait, the hand began to slide again, and he put his own palm against the tiled wall above the toilet cistern to stabilize himself as the motion stimulated him. He felt her moving on his back as he leaned slightly forwards, felt her warmth pouring into his own as the hands worked him, holding him compliant as she stroked him slowly up.
The hand sped up, up, and then up some more, minutes passing as it tantalizingly worked him. He had begun to rock gently into it, helping to pump himself in her grasp as the pace quickened, now moving at a teasing, if palpable speed, about as rapid as slow, early sex might go for the first few thrusts while things stretched and warmed. He glanced down again, saw the edge of his engorged cock, and this time took the silent treatment readily, nearly groaning again as he felt her grip not stop despite the punishing breathing reminder from the other.
All of a sudden, there was a bang and some footsteps, and the bathroom door opened. He froze, not moving, not breathing, not daring to even look around - but her evil, teasing little hand did not. 'Ssshhhhh...' She breathed nearly imperceptibly in his ear. His eyes went wide as he listened to the newcomer, hearing them walk through the room and enter a nearby stall, closing and locking the door. He prayed that they were not in here for the long run, and was relieved when he heard the familiar tinkle of a man peeing. Her goddamn hand never stopped, just sliding gently, softly along his length, teasing and working him as he stood trapped both by her and the other man in the cubicle. He wanted to kick her, to make her stop, to do something - but he couldn't. Any action at all would make noise, and what could he do anyway? Push her off him, hand still grasping his cock, her here only to do him a service at her own risk? Or perhaps grasp her arm and move her away, no doubt only so that she could reach for him again, or perhaps touch something else with the hand that now had at least a little of his lubricating pre-cum on it? He could hardly storm from the cubicle, pants down as he was, erect and slick cock swinging as a woman walked after him. No - like it or not, he was in the best place he could be, and the consistent, loving stroking surely reinforced that idea.
He held on as long as he could, listening in desperation for the other man to finish. He did, flushing and exiting the cubicle. Then, a few moments later, the tap turned on and the soap dispenser crackled.
Of all the men to come in right now,
he thought to himself as that goddamn hand slithered over his helmet once more and down again, twisting gently with each pull,
it has to be a guy who actually bothers to wash his hands properly.
Eventually, paper towels were pulled from the receptacle, and then footsteps rang out as the unknown man walked to, opened, and exited through the door.
