===
Kitka had had a teasing, flirtatious courtship of Eric for two months. They'd kissed on the first date, she'd let him grope her tits through her shirt on the second, but up until tonight she hadn't let him undress her, let alone fuck her. Not because she didn't want to - but because they were both enjoying the thrill of anticipation. They knew it was going to happen - and soon.
They'd talked on video chat to arrange tonight's dinner.
"So when are we taking it to the next level?" Eric asked.
Kitka had smiled, and bit her lip, and said, "Take me out and buy me an expensive dinner, and I think you'll be a lucky man before the day is over." She fiddled with the top button of her shirt, casually unbuttoning it.
His eyes were alight with interest. "Is that a promise?" he asked.
She thought about it, and then said, "Yes. I want you thinking about it all dinner. I want you imagining it. It's the third of the month today. Take me somewhere *decadent* - *romance* me - and you'll have your cock inside me before it becomes the fourth."
She unbuttoned the second button of her shirt, and idly ran her fingers up and down the exposed skin - and then ended the call.
Eric lived up to his end of the bargain. He looked so good in a suit and tie that she wanted to submit to him right then and there. He took her to a restaurant that made her feel like they must have mistaken her for literal royalty just to let her in, and while he never let her see the cheque, she guessed that dinners plus drinks must have come to well over three hundred dollars. She blushed under the intensity of his attention and genuine attraction to her - *all* of her, although her risque black cocktail dress certainly pleased him - and by the time they left she was more than happy to deliver on her promise.
They decided to catch the train home. A taxi would have been easy; but she wanted the pleasure of strolling to the station with him, her arm held in his, his presence by her side.
When they reached the station, though, he turned to her, and said, "It's eleven thirty."
"Yes?" she said, not understanding.
"It'll take forty minutes to reach your house. Longer for mine."
"What do you mean?" she asked.
"If I'm not mistaken, my lady," he said, "your promise was that I'd have my cock in you before it became the fourth."
She blushed bright red as she took his meaning.
He looked at her with a steady gaze, grinning ever so slightly.
Kitka knew she could say no. Eric would never *make* her do anything. Rather, he liked to make her *want* to do what he wanted. If she didn't want to go down this path, she need only ask. But she had a stubborn streak. She had made a promise; suggested a game; and she didn't want him to see her as a woman who didn't follow through.
"Yes," she said, holding his gaze. "I did say that."
He held out his hand. "Give me your panties," he said.
She blushed again, and looked around. There were other people on the platform, though none were looking at her specifically.
"The bathrooms..." she started, but he shook his head.
"You'll miss the train," he said.
She was confused. Didn't he want to fuck her, right now? Why did they need to catch the train?
And then she understood, and blushed even deeper.
Taking a deep breath - which pushed her tits forward in a way he clearly enjoyed - she reached under the hem of her cocktail dress, hooked the hem of her black lacy panties, and quickly wiggled them down her legs, hoping no one noticed. She lifted them up with one high-heeled foot, caught them in her hand, and placed them in Eric's palm, her face bright red.
"Good girl," he told her. Behind her she heard the hoot of an approaching train, and then the rush of air as it pulled to a stop behind her. She didn't look. Eric was still looking at her face, and she was damned if she'd blink first.
Finally, he widened his smile, and looked past her to the train. "Get on," he said.
The boarded the train. Late at night, it was mostly empty, but even so, Eric blessedly guided them to a seat in an empty car.
She went to sit, but Eric coughed. "On my lap," he said. "You're fulfilling your promise, right?"
She bit her lip, and waited for Eric to sit first. He adjusted his pants as he did. A moment later, she lowered herself down onto him - and squeaked.
He had his cock out, poking through his fly. It was rock hard, and as she sat on his lap, it slid smoothly into her naked, eager pussy. She felt it slide straight up her fucktunnel, filling her, until her groin landed on his lap with a satisfying "thud", and she was left, impaled balls-deep on his phallus.
She had to struggle not to moan at how good it felt. She hadn't realised how *wet* she had become since Eric had reminded her of her promise - but she was soaked. She must be leaving a wet patch on Eric's pants. She thought of all the times with a man that she'd had to fiddle to get his bits to line up with hers, and was thankful for her lubrication for making *this time* work perfectly on the first try.
"You still okay?" he asked her.
She didn't trust herself to speak, but nodded emphatically "yes", and made a quiet, primal, slutty sound that she hoped was encouraging.
"Good girl," he said again. God, she loved it when he told her she was a good girl.
She expected him to start bouncing her on his lap, to fuck her, but he held still. She tried to do it herself, but he gripped her waist, holding her in place. She moaned with frustration. Being stuck there, feeling him inside her - feeling him *twitch* from time to time, flexing against her G-spot - was more maddeningly arousing than actually being fucked, it seemed.
He held her there for the entire distance to the next station. The train pulled up, the doors opened, and a few passengers got on. A cute twenty-something girl with coloured hair and a collar, listening to some unidentifiable tune on a pair of headphones, wandered over without really paying attention to their presence, and sat opposite them, not really looking at them.
Kitka had squeaked as the girl approached, and tried to get off Eric's lap, but he held her for a moment, and whispered in her ear, "You can get up, but *I* want you to stay." Then he had released her waist.
Kitka had considered for a moment, half raised, her face blushing - then sat back down on Eric's lap, still impaled on his cock. She looked downward, avoiding eye contact with the girl.
As the coloured-haired girl - "Collar", Kitka thought of her as - took her seat, Eric stared at the girl, getting her attention. Collar caught his stare, and looked at him curiously, lifting one headphone off her ear.
"It's okay to take another seat," Eric said. "There are plenty free. My girlfriend and I are having a moment. But it's also okay to stay, if you like what you see."
Collar looked the pair of them up and down, confused.
Then Eric spread his legs.
When Kitka had sat on Eric's lap, his knees had been together, so she had draped her legs to either side of his.
When Eric spread his legs, it spread Kitka's too.
Collar's eyes widened as the front of Kitka's cocktail dress rode up her thighs and bunched around her waist. She had a clear view of Kitka's wet, shaved, lustful pussy, and Eric's cock buried deep inside it.
