He fucks her

She hesitated, but then nodded. "Alright, turn around." Gale took a deep breath, and obediently spun in place. She felt her yoga pants being rolled down to just under her asscheeks. The thong she wore did little to hide anything. It was quickly pushed aside. She glanced back over her shoulder, and barely contained her moan as she felt his cock slide all the way into her wet, warm pussy. She arched forward. She was expecting him to grope her, or maybe finger her. The feeling of his cock filling her up shocked her into silence as she saw her reflection and his grinning face in the window.

"How did it come to this?" she asked in a husky voice as he slowly fucked her. His thin, long penis arching up and into her in a steadily increasing rhythm. The man in front of her turned around, and stared her in the face. She held the overhead hook with both hands, leaving her massive chest undefended. The man grabbed her breasts, squeezing and kneeding them. Other hands found her body, exploring and fondling her as the punk started slamming into her faster and harder. Her turtleneck was rolled up her body, and the roaming hands quickly freed her heavy breasts from her bra.

"Women. In Japan, women don't get the luxury of marrying someone they love, and the husbands would beat them savagely if they were caught having an affair. So, they ride the trains, get their thrills, and the husband never has to know. Nice cunt, by the way." She looked around. No one was even looking at them, and this guy was fucking her in public. "The husbands get some cheap thrills without cheating on the wife. Schoolgirls get to experience sex without a bunch of rumors about them being sluts, schoolboys get to get their rocks off without a stern father watching their every move, and the whole country gets to do stuff that lets off some steam, and gaijin like you get to fuck whoever they want and then leave. Everybody wins."

She was gripping his wrist hard as he fucked her, and shamefully close to orgasm. Two men were sucking on her swaying nipples as another held her up. The punk behind her was gritting his teeth.
He tensed up, and she felt him slam deep and fast into her. She bit her finger, her body spasming hard as the orgasm ripped through her. She'd been fingered on a dancefloor at a club once and sucked a couple guys off in dive bar bathrooms, but nothing like this. She felt her pussy clamp down on his thrusting cock as she came. Her body gyrated and heaved as she tried her best to keep quiet. He held himself close, and slowly drew it out. She heard him pull the condom off and zip up his pants. The man said something in Japanese, and all the fondling stopped. Gale rolled her yoga pants back up, and turned around.

"I think that's all the questions I have." she said, stuffing her breasts back into her bra before pulling her turtleneck back in place. She was blushing badly, still quivering from the orgasm. He nodded.

"Glad I could help." he said before squeezing his way through the crowd. She felt the train slow. This was her stop.
