Brook slipped out through the front door and crept quietly around the side of the house. Her mother was in the hot tub with Tom tonight, and after listening to them play naked under her bedroom window almost nightly for the past two weeks she found herself overcome with curiosity to watch them. She'd peeked at them through the window as well, but the angle from there didn't provide the curious eighteen-year-old a very satisfying view. She wanted to see as much as she could.
The compactly built young brunette wasn't used to living in a house as big as Tom's, and for that matter, she wasn't used to living with a man in the house at all. It had always just been the girl and her mother. She'd never known her father, and since Janice, her mother, had rarely mentioned him over the years the girl never had too much curiosity about him. Those times when she did wonder about him Brook rarely bothered asking questions, assuming her mother didn't like talking about him. Growing up with a single mother was simply Brook's reality. Just a couple of times a year the girl imagined what it would be like to have a father in her life, but she kept that to herself.
Ultimately, their life together had always been comfortable, if not especially flashy, and making any major changes never seemed an important issue. Janice had gone out with plenty of men over the years, but she rarely ever brought one home. Consequently, her sudden marriage to Tom seemed completely out of character for the sexy, attractive thirty-six-year-old.
Brook had liked Tom well enough when he started spending time at the apartment where she and Janice lived before. It was nice having him around. He was always funny and friendly, and sometimes Brook imagined it was what it would be like to have a father in her life. But the couple would always disappear into Janice's bedroom early in the evening and probably had no idea how the sounds of their ecstatic fucking bled through the thin walls.
At first, Brook just laughed it off and either turned up the TV or stuck in a pair of earbuds and listened to music. But it wasn't long before she was retreating to her own bedroom and listening to the distracted pair with her hand between her smooth, young thighs. She probably had even more orgasms than they did.
Then one afternoon Janice called Brook into the kitchen in the apartment they'd been living in, saying she wanted to have a serious talk. The first bomb the girl's mother dropped was that Tom was Brook's father. She explained that they'd had a casual relationship years before, and it was over by the time Janice discovered she was pregnant. The reason she never told Tom was that she never wanted a man sticking around because he felt like he had to. It wasn't what she wanted for herself or Brook.
Brook was okay with that. She knew her mother had devoted herself to giving the two of them a good life, and despite the girl's occasional daydreams of having her father in her life, it wasn't as if she could say life with her mother wasn't a good one. Then Janice told her Tom had asked her to get married, and have both mother and daughter move into Tom's big house. It all came so quickly Brook wasn't sure what to make of it. As much as she liked Tom, it was a lot to take in all at once.
Janice told her daughter that day that she wanted to say yes. She was in love with Tom, but she didn't want to make any decisions without including Brook. As they sat and talked things over, Brook got to like the idea more and more. She wanted her mother to be happy, and she also realized that having her father in her life was probably more important than she ever admitted to herself before.
Tom was older than most of the men Janice went out with, but he was incredibly handsome and in really good physical shape. He always seemed warm, upbeat and friendly. Brook didn't know if she loved him or not. He was still someone new in her life and now that she knew he was her real father she wasn't sure how she was supposed to look at him. But her mother assured her that time would take care of everything and they could be a happy family.
Brook was still getting used to everything. She had a really nice room and even her own private bathroom. There was the hot tub and swimming pool, and a lot of property with enough woods around to give them total privacy from the closest neighbors. It all seemed so nice, but at Tom's, she couldn't hear them fuck as easily as she could back in their old apartment, and oddly enough that made her feel disconnected. It wasn't hard to sneak down the hallway and listen through their bedroom door, but it didn't feel the same as when she could lie in her own bed and touch herself.
Brook decided to be cautious about Tom and settling in to her new surroundings, although she didn't want to do or say anything to spoil things for her mother. Janice was the happiest she'd ever seen, so even if Brook was keeping a little distance on the surface, she still didn't want to do anything to make waves. Back in their apartment, she was around them more just because the place was smaller, although it seemed like they spent most of the time closed up in Janice's bedroom. In the couple of weeks since the move, the girl spent a lot more time on her own in her new bedroom.
The curious eighteen-year-old now padded out of the house barefoot, wearing a loose pair of drawstring shorts, without panties, and a cropped T-shirt without a bra that she planned to sleep in. She was petite, with tightly compact curves, but she often wished she had bigger tits, even though her legs were shapely, curving into a pertly rounded ass.
As she approached the cover of the bushes at the rear corner of the house, she could hear her mother's and Tom's voices before she could see them. The view through the bushes was partly obscured by leaves and branches, but the outside lights were on at a dim setting, and the couple were both sitting totally naked and soaking wet up on the bench that went around the upper edge of the tub.
Brook couldn't help feeling proud of how good her mother looked naked. No wonder Tom was crazy to fuck her night after night. She looked like a slightly taller, curvier version of her teenaged daughter. The girl found herself wishing her tits were as big as her mother's, even though they were pretty close. But Brook was actually proud of her tits and often wore low cut tops that her friends' mothers would probably complain about. Yet Janice was the same way, and she never said anything about the things her daughter chose to wear. How could she when she was usually dressed the same way?
Brook was surprised to see her mother's pussy was as smooth and hairless as her own, and Tom's hand was barely a couple of inches from her slit as he casually rubbed the inside of her upper thigh. At the same time, Janice had her hand wrapped around Tom's lust engorged cock, and Brook nearly gasped out loud when she saw how big it was. He seemed huge. No wonder he made her mother cry out with pleasure from their bedroom every night.
The girl's experience with cocks included a little bit of internet porn, and just three guys from school that she had jerked off, but this man whom she had only recently discovered was her father made them look downright tiny by comparison. She couldn't help feeling a huge sense of pride. Not that she knew why. It wasn't like it was something she could brag about to her friends. And above all, it wasn't like Tom's cock was available to her, but she didn't know if she'd ever be able to look at him the same way.
Daddy's got a huge cock, she muttered under her breath. It was barely a whisper, but it gave her a warm, tingling sensation just to say the words. She'd never even called him Dad. It was all so new she didn't even know if she was supposed to. She wanted to, though. And for some bizarre reason she couldn't explain, now that she knew how he was built she wanted to call him Dad more than ever.
She also felt proud of her sexy mother who was skimming her hand up and down Tom's enormous shaft like it was nothing. The girl wished she could be just like that, pleasing a man like Tom - no, pleasing Tom himself, her own father - like it was what she was made for.
Then Tom slid his hand directly over her mother's pussy and stroked her lips with his large fingers. Janice threw her head back and sighed deeply, grinding her hips while he fingered her slit with an affectionate smile on his handsome face. At that point, Brook didn't want to be like her mother, she wanted to be her mother. Her young pussy quivered with damp heat as she yearned to be fingered just the way Tom was fingering Janice.
The trembling girl gnawed on her bottom lip and slid her hand into her shorts to stroke her own pussy, trying to imagine Tom's finger along her moist slit instead of her own. His fingers were so much longer and thicker than hers. Her pussy flushed steadily as she watched the naked couple casually play, but after a while they backed off and picked up their wine glasses, taking a breather.
Tom looked preoccupied, which Janice quickly noticed and asked what was bothering him. Holding her wine glass in one hand, she put her free hand back on her husband's huge cock and continued to lazily stroke him.
"Something bothering you, baby?" Janice asked.
