The subway train was crowded as usual in the morning rush hour. Passengers were pressed together tighter and tighter as the train stopped at stations and more got into the carriage. The guy had seen the young woman get on the train when he did and he now found himself pressed tight up behind her as the train swayed and rumbled onto the next stop. More people crammed into the carriage and, as the train started with a jolt, they were all pushed together. He was tempted to murmur an apology as he was catapulted against the young woman but no-one usually bothered. It was the usual discomfort of early morning commuter travel. She merely turned and looked at him then looked away again. He caught the smell of her perfume as she turned. It was alluring. The train lurched again and once more they made contact. He fancied that, this time, she deliberately pushed herself back against him ...... or did she? Was it just his imagination? His stop was next and the train stopped. She got off as well and walked in front of him along the station platform. Once she stopped briefly to turn her head and he realised that she was checking to see if he was there. He slowed his step and followed her along to where a dimly lit, blind side-alley ran off the main train platform. A sign announced that the door there was 'For Staff Only'. She turned into the side-alley. He followed. She was leaning back against the tiled alley wall beyond the Staff Door and as he approached she hitched her short skirt up around her waist. He stopped and stared at her smooth white thighs exposed above the tops of her stayups. She stared boldly back at him as she hooked her thumbs into the waistband of her panties and pushed them down. He gazed at the furry triangle between her thighs as she began to stroke herself. What should he do? There was another train entering the station followed by the sounds of hard heels tapping on the pavement. Passengers hurried to their workplaces and no-one entered the dimly lit alley. He felt his cock surge as the woman opened her legs and slid a finger into her pussy. He moved towards her and when he was in front of her she flung her arms around his neck and pushed her thigh between his. He buried his mouth in her neck and smelt her alluring perfume again. As he kissed and nibbled her he felt her hand reach between his legs and squeeze his balls and the growing bulge of his swelling cock. Her fingers deftly unzipped him and slipped inside his pants. She lifted his thickening cock from his clothes as he hurriedly pushed them to the ground. Her hand steered him between her legs and his cock slid along the length of her hot wet slit. She was ripe for fucking, Her slit was hot and exceedingly wet as she stroked his cock between her pouting cunt-lips.He bent his knees and angled his shaft upwards as she pushed down on his tip. Two loud gasps sounded as he entered her hot, slippery sheath then he was slamming her against the hard wall as he began to thrust fiercely into her. Another train arrived and their gasps and moans were heard by one or two passengers who paused to locate the sounds. One or two young men stopped and looked on with amused grins on their faces as they watched the couple fucking. Others, mainly older women, tutted and hurried on. Gradually a small crowd had gathered at the entrance to the alleyway and watched as the woman lifted her leg up around his waist as he supported her fine ass in his hands. He lifted her up and down on his hard cock as she locked her leg around him and answered his thrusts with thrusts of her own. One or two of the onlookers began to call out encouraging words as they watched the sex display and there was more than one stiff bulge in the pants of the watching men. The couple were oblivious to the onlookers until the urging words reached their ears. The woman turned her head and grinned broadly at them as the man kept fucking her, intent only now on releasing his load into her hot accepting body. He pumped her hard and shot his heavy load into her with a strangled cry of triumph. Moments later he pulled out of her and wiped his cock on her panties as the crowd drifted away. She straightened her skirt and took the panties from him to put them in her handbag. As she turned to walk away on her shaky, shapely legs she said, "Whew! I enjoyed that, dear! Don't be late home tonight, will you? I want a lot more of that yet!" He grinned back at his wife as he said, "OK my dear! I'll hold you to that ........ and to something else as well!"
