(As always, starting with the first chapter is best. Long ago I had something somewhat like the bathtub scene actually happen....)
That Friday night, Charlie's new 22-year old stepsister, Alice, regaled them all with tales of her first day as the assistant manager of the huge used bookstore that they sometimes went to. It had been a very good day, she said, even though she realized almost as soon as she'd started that she'd overdressed for the job. Everyone who worked there dressed professionally but casually, and the next time she went into work, on Monday, she planned to ditch the glam-Goth professional look that she'd worn for just a slightly more dressed up version of the neo-hippy chick that she was. Almost everyone was nice, Alice said, and she spoke especially warmly about her fellow assistant manager Craig, who had been so helpful at talking her through things. Hearing this, 18-year old Charlie got a pang of jealously, which was a weird feeling that he'd never had with this intensity before.
Charlie's Mom, Sylvia, and new Stepdad, Ted, were glowing with pride as they listened to the description of Alice's new jobโhow how responsible it was, how it didn't keep her at all from working at all of the other jobs in the store just like the other employees, how successful the company was, how successful and well-organized their particular store was, and so on.
Finally, with apologies, Sylvia and Ted interrupted Alice's seemingly endless stream of words to switch over to giving her and Charlie instructions for when they were going to be gone. Starting the next day, Sylvia and Ted were leaving for a romantic retreat to Big Sur, leaving Alice and Charlie alone in the house for the weekend.
Sylvia and Ted said to be careful, but have fun, and absolutely no guests over because of insurance reasons. Call 911 if any serious accidents or anything really bad happened. And call them too, of course, but they trusted that nothing would go wrong.
Charlie stole a furtive glance at Alice as this was being said, and she glanced quickly back at him with a definite don't-look-at-me-right-now expression. To their parents, they just replied that they'd do what was said, and as Charlie thought it over he realized that going by the exact legalistic letter of it, maybe they sort-of would, in a twisted way. But for the first time he more fully realized how much they were playing with fire in fooling around, which they had already been doing for the last few days. As Alice had warned him, there didn't really seem to be much of a future in their just-started affair, for he couldn't imagine the fallout if their parents found out.
After getting in his PJs and brushing his teeth, he got into bed to await his nightly kiss from Alice, feeling waves of worry. He started planning to say to Alice that maybe they should think this over, when suddenly there was a light knock on the door.
"Good night, Charlie," Alice said, in a neutral voice, without coming in, "See you tomorrow."
"Good night," he replied, trying to sound like nothing was wrong. Alice skipping their newly established ritual of the goodnight kiss made him even more worried. Was she freaked out too? Maybe now whatever she had planned for their weekend together was off?
He tossed and turned in worry for a couple of hours before he finally slept.
Oversleeping, he awoke in full daylight, and wondered if he'd already missed seeing his Mom and Dad off on their trip. Quickly putting on his robe and brushing his teeth, he rushed out to the living room, which was already quiet and empty. Going out to the driveway, he saw Ted and Sylvia putting their suitcases in the trunk of the car. Alice, already dressed, was smiling and waving goodbye. Seeing Charlie they all smiled at him and waved. He could see that their little poodle Penny was in the car, jumping up and down in the back seat. The dog loved going on trips. And then there was a last round of goodbyes, and their parents were gone.
Charlie smiled shyly at Alice after the farewell. And in response she looked at him quizzically. He hated himself, but suddenly the idea of being alone with Alice in the house for the whole weekend, without even having to worry about their parents and about being discreet, seemed a little scaryโbecause he simply didn't know what to do.
To hide this, he yawned a little theatrically, and said, "I just woke up."
She smiled, "I know."
"I think I'm going to go take a bath," he suddenly added, and walked back into the house.
Once he got in, he kept walking until he got into the bathroom, closing but not locking the door as was his agreement with Alice, and starting the water flowing. He stripped rapidly and got in the bath, which slowly started filling. He was feeling more than a little anxiety, but maybe the bath would give him time to figure things out.
Then there was a knock at the door, and without waiting for an answer Alice came in.
"Charlie," she said, and he turned off the water so that he could hear her better.
"Yes?" he said, sitting cross-legged at one end of the tub, feeling more or less safe behind the opaque curtain.
"Can I get in with you?" She said, and he could hear the smile in her voice as, again without waiting for an answer, she rapidly took off her clothes.
"Well....," he said, stalling for time, thinking that he'd never had a bath with anyone else before.
But it was too late. Alice pulled the shower curtain aside, and he could see her completely nude right outside of the tub. She smiled at him as he looked at her beautiful medium-small slightly upturned breasts with their small nipples, and then at the dark triangle of her black-haired pussy.
And then Alice lifted one leg to get into the claw-footed bathtub. To Charlie, this seemed to be happening almost in slow motion, but soon she had one leg in the bath and one leg out. As a result, just two feet away from him, almost directly in front of his face, was Alice's hairy vagina, which for the first time was spread open in front of him.
He saw rounded hairy mounds on each side. And then in-between her spread legs was the actual opening of Alice's vagina, which was like a curvy, lippy, upside down folded together V of moist light pink, with the mostly hidden bud of her clitoris above.
Alice said, "Oh, the water's hot!" and seemed genuinely surprised by this, and rather than getting in all the way, she stayed in this position for a few seconds as she got used to the water. She watched Charlie's look of wonder and lust as he stared at her spread cunt directly in front of him.
The water was still shallow, and Charlie's cock head jerked out of the water as it filled with blood. It looked like a rapidly growing mushroom.
And now it was Alice's turn to be fascinated, because although she'd seen soft dicks and hard ones, she'd somehow never seen one go from soft to hard right in front of her eyes. And she was turned on to know that she had just caused this with the spread view of her twat. And so she stayed in the the same position for a little while longer watching him grow.
Now Charlie's penis with it's light purple head was jerking up higher and higher, and in just more several seconds it was six-inches of rock-hard cock pointing almost straight up in the air. The purpleish head of Charlie's twitching and throbbing penis now stretched up to just past his belly button as he sat there cross-legged.
Alice climbed the rest of the way into the tub, and then sat down very slowly, saying with a hint of wonder, "Good morning to you too. Thanks for that." And then she added with a really big smile: "That was hot!"
Suddenly, Charlie's shyness was almost gone. He loved Alice, and she was so fun and accepting of so many things. Now his worry was mostly gone, and he was just trembling with excitement.
"I'd never seen that before," he said, with an excited and shy smile.
"Actually, I haven't ever seen a guy's cock grow like that right in front of my eyes either," Alice said, trembling a little with excitement herself.
Charlie's breathing was coming rapidly, and she could almost see his heartbeat thumping in his chest.
"I think we can do something about this," Alice said with a smile. "You said you sometimes did it four times a day, and so it's not like we're going to run out."
He looked at her puzzled.
"Stay right there," she said with an almost ironic smile, "I'll be right back."
And then she slowly got up and, standing, turned around to face the shower head, which had hanging off it a wire rack with shampoo and conditioner bottles. She leaned over slightly getting one of the bottles out of the rack
He was now looking at Alice's butt, which somehow surprised him with how different it was from a man's. It was larger, rounder, softer, and almost heart shaped
"I think just a tiny bit of conditioner should do the trick," she said, and she picked up a bottle and started opening it.
