Chapter 1 - Penny Rides the Train

"Excuse me, is this your daughter?"

Penny had noticed the woman the moment she entered the train carriage. She was tall, or at least her shoes and straight, confident posture made her seem that way, dressed in business attire that was casual enough to show some cleavage. Penny wasn't very good at judging the age of people more than a few years older than herself, but when the woman started reading some papers from her briefcase she put on glasses and Penny's mother had recently started doing the same thing so she guessed that she was in her early forties.

The woman had sat down across from them without giving them a second glance, much less the woman with the stroller or the older woman reading a magazine seated on opposite ends of the carriage. Penny had pretended to be busy with her phone but secretly she'd watched the woman from under her bangs.

She didn't use to be this fascinated by women, by looking at their bodies.

If only that had been the only thing that changed.

But then the woman had put her papers away and looked at them. Penny's heart had skipped a beat when she saw the woman's gaze flick down between her legs, the way she smiled when she saw...

"Oh yes, this is Penelope. Say 'Hello' to the nice lady, Penelope."

Penny swallowed, too flustered to meet the stranger's gaze.

"H-hello, ma'am."

"So adorable. And she's a futa, I see?"

Penny blushed and shifted in her seat. The question was a pure formality as her dress was, in accordance with law and custom, short enough that the tip of her penis was visible beneath the hem. She resisted the urge to cross her legs, assisted by the discreet touch of her mother's hand on her thigh.

"That's right. She turned just a few months ago."

Penny could hear the beaming pride in her mother's voice. She felt herself blush even more, partly over being praised in public and partly because her mother had never showed this level of pride in her before she became a futa, no matter how well she did in school, or in ballet, or with the violin, or on the volleyball team.

Now all that was over with, of course. Those feverish, half-forgotten weeks when her penis emerged had changed her life for ever. Being a futa meant she wasn't meant for academics or art or sports. She was meant for...

"Oh, a late bloomer! How exciting that must be!"

Penny's cheeks burned again. Most girls turned in their early teens and had plenty of time to get used to their condition before anyone else was allowed to touch them, but she was almost nineteen. For some reason there were a lot of women who seemed to find it enticing that she was so inexperienced.

"Do you mind if I take a closer look?"

"Not at all! Penelope, be a good girl and join... what's you're name, if you don't mind me asking? I'm Carmen."

"Oh, I'm so sorry, I completely forgot to introduce myself! I'm Marie."

Marie and Penny's mother both half-rose from their seats to shake hands. The slight shake of the carriage made them a little unsteady which drew smiles from them both.

Penny sat frozen in her seat, even though she had been almost certain that this was what was coming, anticipation and embarrassment fighting to a standstill inside her. It wasn't until her mother touched her shoulder that she succeeded in defeating her paralysis and rose to her feet to stiffly cross the train carriage and sit herself down in the seat next to Marie.

Penny put her hands on her thighs like she had been taught, ready to pull up the hem of her dress if that was requested and out of the way if the woman - Marie - wanted to put her hand between her legs, and she kept her knees pointed outward at a slight angle to provide easy access to any such explorations. She kept her eyes closed, unable to meet her mother's proud gaze and too embarrassed by the sensation of her penis starting to grow to look down.

Marie changed her posture, turning halfway towards Penny, reaching out to draw her fingers up and down her bare arm.

"That's a very pretty dress, Penelope. Is it new?"

"Y-yes, ma'am. W-we bought it l-last week."

Penny's mouth was dry and she could feel her heart pounding in her chest. The only one watching was her mother, the woman with the the stroller having left at the last stop and the older woman still busy with her magazine, but being out in public still made Penny nervous and having someone... do things... to her where others could see was extremely embarrassing. Her mother kept assuring her she'd get used to it, but she didn't see how she could ever feel like it was normal. All the other futas she'd seen or met had turned when they were much younger, but for Penny there hadn't been any time to acclimatize.

"If you've gone through the change so recently, then you still have your ribbon, yes?"

"Y-yes, ma'am."

"May I see it?"

Penelope swallowed.

"Of... of course, ma'am."

Penelope gripped the hem of her dress with stiff and sweaty fingers, slowly pulling it up to reveal more of her penis, including the silk ribbon tied around it with a small bow.

All futas wore the ribbon for the first year they were publicly available, as a reminder to their users that they were inexperienced and should be handled gently.

Penny's ribbon was a dark red to match the accents on her otherwise pink, frilly dress. Her mother had tied it for her this morning, making sure it was tight enough to not fall off when she was soft without being too restrictive when she was hard.

"Oh, that's so cute!"

Marie reached down and drew the backs of her bright red nails down the shaft of Penny's penis. Penny couldn't fully suppress a shudder as her breath caught in her throat at the light touch, a deep blush burning her cheeks as she felt her member start to respond.

"Such a pretty little cock. I'm sure all the other futas are jealous."

Penny boggled at the thought of anyone calling the meaty appendage between her legs 'little' so she instead of trying to respond she kept quiet and focused on her breathing, struggling to keep it slow as Marie kept teasing her penis with her nails and fingertips. The older woman shifted in her seat, her breast pressing lightly against Penny's arm as she leaned in close enough for her breath to wash over Penny's bare neck.

"If you only turned a few months ago you haven't had many women touch you yet, have you? Is that right, Penelope? Am I one of your first?"

Penelope nodded stiffly, swallowing before she found her voice.

"Y-yes, ma'am. We... we've only been o-out a f-few times."

Penny felt her penis start to rise under Marie's gentle fingers, her pulse pounding in it as it swelled.

Marie pressed her smiling lips against Penny's neck and pulled her dress down enough that she could kiss Penny's shoulder.

"You don't need to be nervous, pretty Penelope. I'll only use my hand. But I would very much like to make you cum. Would you like that?"

Marie's voice was a soft, hot whisper against Penny's skin, and she felt herself nodding. It was true, she did want to cum, in spite of the embarrassment of doing so in public. The constant worry that she would meet someone she knew, one of her friends from school or from the volleyball team, or that they would hear about how she had been used, that worry was still there but it was receding in importance, smothering under the warm, insistant, pounding need in the pit of her stomach.

She was also surprised. So far, the few women she had interacted with had wanted her to jerk off for them or else just tease her to make her hard.

"Y-yes, ma'am."

She had never been this easily aroused before she turned. Sure, she would get turned on and masturbate from time to time, but now it happened constantly. Between her few encounters with women in public she would get uncontrollably horny and masturbate at least every few hours, sometimes one time after the other several times in a row.

Marie wrapped her fingers around Penelope's slowly stiffening hard-on. She stayed true to her word, her touch very gentle as she started to move her hand up and down very slowly, languidly stroking Penelope's member.

"Not so little anymore, but just as pretty. Let's see if we can't make it bigger still."

Penny tried to stifle a moan as Marie did something with her fingers around the edge of the tip of Penny's cock.

"Say it, Penelope. I want to hear you say it."

Marie's voice was gentle but insistant.

"Say you want me to make you cum."

"I... I want you to make me... make me... c-cum... ma'am."

Marie smiled against her neck again, then kissed her, again, again, higher each time, until she caught her earlobe between her lips, sucking it gently before letting it go.

"Very good, Penelope. You're such a good girl."

Penny leaned her head away from Marie to give her better access and the older woman took full advantage of this, her lips and tongue wandering up and down Penelope's neck as she kep slowly stroking her long, thick, stiffening shaft with one hand while the other played with her hair.

"You really do have a beautiful cock. Once this ribbon comes off" - Marie trailed the edge of the inch wide band of silk with her fingerips - "there won't be a woman around who won't want you to stick it in her."

Marie took a firmer hold of Penny's almost fully hard cock - God, she was really starting to use that word even in her own mind - and shook it playfully, then started stroking it again, a little faster now, then she slowed down and squeezed, not too hard, just enough to push a little drop of clear precum out of the tip.

Marie shifted her grip and caught the drop with her thumb, then spread it over the tip of Penny's cock. The intensity of the sensation made Penny gasp and buck her hips against Marie's hand. The older woman grinned and continued to rub her thumb over Penny's sensitive glans.

"Have you tasted your own cum, Penelope?"

Penny shivered, both at the pleasure of what Marie was doing to her... her cock, and at her words.

She had tasted her own cum, once out of curiosity and once as an accident when she had masturbated and her release had been particularly forceful and plentiful, spattering up over her chest and onto her lips. Both times she had found it simultaneously repulsive and erotic, somehow taboo and shameful.

But as Marie kept rubbing her tip with her thumb, Penny found she couldn't lie to her. She bit her lower lip and nodded, her eyes tightly closed as her cheeks burned with shame again.

"Don't worry, it's nothing to be embarrassed about. Some futas quite grow to like the taste of their sperm."

Marie squeezed Penny's shaft again and drew her thumb over the tip, collecting another shivering, translucent drop of precum. She released her grip on Penny's cock and raised her hand, wafting the musky scent of the fluid towards Penny's nose.

"Why don't you try it again? For me? I'd enjoy that very much."

Penny wanted to refuse, this was just one step too far, but the combination of Marie's insistant voice, the pressure of her breast against Penny's arm, and Penny's own arousal wouldn't let her. Her lips felt numb when she parted them, but when Marie told her to stick her tongue out she obeyed.

When Marie wiped her thumb over Penny's tongue she made a face at the taste, salty and strange and somehow at once disgusting and delicious, but then Marie's hand was back on her cock, stroking her fast, and the shock of pleasure every time her fingers rubbed the edge of Penny's glans overpowered her shame and revulsion, making her pant and draw the scent deep down her throat.

When Penny found herself again she scrunched her face up again but before she could make to spit Marie's other hand covered her mouth.

"Swallow, Penelope. Always swallow, unless you're told to spit."

Penny tried to turn her head but Marie's hand followed, her voice whispering in Penny's ear.

"Swallow. It's just a little drop. Swallow, and I'll let you cum right now. You're close, I can feel it. I'm sure just a little more would push you over the edge, isn't that right?"

She sped up her strokes for just a moment to demonstrate her point, and Penny half-rose out of her seat as a spike of pleasure hit the pit of her stomach.

"Yeah, that's what I thought. Swallow, and you can cum right now... or I can keep this going for a lot longer."

Penny tried to resist, but the need and frustration she felt when Marie demonstratively slowed her strokes was too much. Besides, the droplet of precum was so diluted by her spit the taste was almost gone, so it wasn't really like she would be swallowing cum, was it?

She swallowed, and Marie cooed in her ear.

"That's such a good girl. Now cum for me, pretty Penelope. Cum for auntie Marie."

The older woman was true to her word, her hand speeding up as she tightened her grip on Penny's cock, stroking it in quick bursts as she kissed and sucked Penny's neck and shoulder.

At frist Penny thought she wouldn't be able to get there, the swirling emotions inside her frustrating her need for release, the lust and shame and embarrassment and arousal and sudden affection for this unknown woman all mixed up together, but then Marie did something with her tongue just below Penny's ear and all that went away and she felt herself thrust her hips against Marie's hand as a wave rose inside her, fell back, and then rose again, cresting as the line of fire rising from her crotch all through her body exploded. Her body tensed and released again and again as her cock pumped in Marie's stroking hand, and she heard herself cry out as she shot her load over the floor of the train carriage, spurt after spurt of her cum forced through her rock-hard shaft and ejected from her throbbing tip, the scent hitting her nostrils and reawakening the taste on her tongue. She kept cumming, and cumming, and cumming, Marie's skilled hand drawing wave after wave of ecstasy from her body even as her hard-on started to flag and her cock shrank in her grip, the ribbon chafing the suddenly sensitive skin, but the aftershocks as Marie's fingers rubbed the underside of the edge of Penny's glans were powerful enough to make her gasp and shiver.

When Marie raised her hand the scent of Penny's cum hit her again she wrinkled her nose, but Marie's tongue below her ear made her gasp again, and when the older woman touched her fingers to Penny's lips she let them inside.

The taste was much, much stronger now, but somehow that made it more bearable, even though the cum itself was slimy on Marie's warm fingers. The taste wasn't just stronger, but deeper, more textured, and after some hesitation she found herself sucking Marie's fingers and probing them with her tongue to find more traces of it. Marie smiled against her neck and let her continue to suck her fingers, moving them slowly in and out between Penny's lips.

Then the train slowed down and Marie pulled her fingers out of Penny's mouth.

"This is my stop, I'm afraid. But I hope I will meet you soon again, pretty Penelope."

Marie turned Penny's face towards her and placed a warm, gentle kiss on her lips.

Penny raised her hand to numbly wave goodbye as Marie picked up her briefcase and stepped off the carriage with a final smile over her shoulder.

Penny shook herself and looked around. Her mother was beaming proudly at her but nobody else seemed to have taken notice of what had transpired. When she looked down she saw the mess she had made on the floor in front of her, wet spattered stains surrounding thick globs of semi-transparent cum.

"Don't mind that, Penny. Someone will clean it up later. Just be careful where you step."

Her mother waved her back towards her seat, and Penny gladly obeyed, snuggling up against her mother's side as she laid her arm around Penny's shoulders.

"I'm so proud of you! You did so well!"

Penny's mother kissed her forehead.

"Maybe we should ride the train again tomorrow? Would you like that, sweetie?"

Penny hesitated for a moment before nodding. She still felt embarrassed about being out in public where anyone could ask to use her at any time, but maybe... The handful of times she had been used before when she had been teased or asked to jerk off had mostly been embarrassing, but if this had been exciting and very pleasurable. If there were more women like Marie then maybe being a futa wouldn't be so bad after all.
