*****
This story takes place two months after the first part, which I recommend reading but it isn't necessary. What you need to know is that Sarah is spending the summer with her Uncle in the woods, working to build a house. She left behind a boyfriend of a year, whom she was very fond of and planned on continuing to see throughout the summer, calling him every Tuesday and Thursday night. Last story ended with Sarah and her Uncle, Aaron, having sex for the first time on the porch, with Sarah volunteering to become her Uncle's sex slut—he has a thing for domination, and Sarah wanted to see where it goes.
This story's tone, like Aaron and Sarah's relationship, is completely different than the first story. It's BDSM for a reason. It includes anal, body markings, domination, exhibitionism and incest. Everyone is over 18.
***
Uncle Aaron sat at the makeshift dining table, waiting for his niece Sarah to arrive at the house. It had been almost two years since they'd last seen each other, at the behest of her mother, but he remembered her well enough, and was excited at the fact she was coming to spend the summer here. Her mother had panicked when he first extended the offer, worried about what might happen to her daughter during a summer with him. Surprisingly, though, her husband was a big fan of the idea. The thought of her husband sending his daughter to spend a summer with him brought a smile to Aaron's face. The fool had no idea, he never had any. Aaron gave it two weeks before Sarah was his, give or take a few days. It would be another woman to add to his collection and the youngest he'd had in a long time.
When the sound of the tires on the dirt driveway stirred him from his thoughts, he laughed and got up.
***
Sarah woke up, like she has the past two months, with her Uncle's arms gently wrapped around her bare waist, her ass pressed against his exposed cock. Feeling playful, she gave her ass a wiggle, trying to wake the beast. She felt the head of the large man behind her move, taking it as a sign that Aaron was slowly waking up. When calloused fingers moved from her waist to her tits, pulling and stretching at her nipples, it became clear he was ready for the day.
"Good... morning... baby," Uncle Aaron said between kisses along the back of her neck.
"Morning daddy," Sarah said back, smiling as she uttered the name he wanted to be called and feeling his cock stiffen against her left ass cheek. "What do you want this morning?"
"Hmm... how about we do this the old-fashioned way?" Uncle Aaron said, flipping over so he now hovered above his nude niece. Sarah's legs were already wide opened, her cleanly-shaven pussy swollen and ready for its morning snack. She'd shaved there for the first time the morning after her Uncle first fucked her, he'd demanded it of her—the first of many demands made of his newly-created slut. Sarah didn't think much of it at the time, inconsequential as it was. But that was the mastery of Uncle Aaron, asking Sarah to make one move at a time, changing how she behaved, what she did one thing at a time.
First, she shaved her pubic hair and didn't wear any underwear. Then he asked for blowjobs in the morning, which scaled to being face-fucked almost immediately. By the end of the first week, she could take her Uncle's 8-inch cock all the way down her throat.
Now, staring into her Uncle's eyes as he lowered himself into her cunt she moaned out, like an addict getting her fix. She loved that cock, more than anything before. Aaron taught her that his cock was the world, Sarah knew it was true. As he picked up his pace inside her, she reached out to feel his strong chest twitching with each movement, enjoying the sight of his abs expanding and shrinking.
Pulling out, Uncle Aaron lay on his back, "Ride me, bitch." Sarah immediately followed suit, hoping up and lowering down on his cock before moving her hips forwards and backwards, milking his cock. Again, Aaron's hands reached up to her tits, "How are they?" He asked, nodding at the nipple rings she'd gotten four weeks ago.
"Still a little sore, but that just makes it feel better when you pulled on them, sir," she gasped out, words matching her rhythm. A gift from Uncle Aaron, they marked one month of being together and formed a ring just wide enough to fit a thin rope through them. Sometimes, late at night when he's feeling extra dominant, he loops a rope through each of them and leads her around the unfinished cabin like a dog. Or he pulls at them in the middle of sex, just to see how far her tits could stretch.
With her mind on the nipple rings, Sarah's hands absentmindedly ventured down to her waistline, feeling at her new tattoo. She got it the same day as her piercings, on the left side of her waistline the Sanskrit words for "Daddy's slut" reminded her of what she was. Believing it was her own idea, Sarah loved the thought of being marked by a man as nothing more than a playtoy.
"Oh fuuuuck yeah daddy, that's the spot," Sarah yelled, awoken from her stupor by a particularly powerful thrust.
"That's it baby girl, tell me who you are," Uncle Aaron demanded, slapping at one of her C-cup tits.
"I'm your fuck slut, daddy, and you can use me however you want."
Two more minutes and Aaron came inside Sarah, who collapsed to the side, tired and sweaty already. For the fifth day in a row, she hadn't cum, and was beginning to suspect that was some sort of ploy—she knew uncle Aaron could hold off long enough for her to cum.
"Come on baby, time to do some work. We need some insulation before it gets too hot in August," Aaron said, looking away from his naked niece sprawled on the bed. Sarah listened absentmindedly, enjoying the view of his hairy ass and ripped back as he pulled on some boxers and jeans. Once he left, she begrudgingly got up and walked over to the makeshift bathroom. She looked at herself in the mirror, like she did every morning, and took in her curvy frame. Her tits were red from being pulled on, the silver rings sparkling from the new morning sun, she gave them a jiggle, watching the rings flop up and down again. The dark Sanskrit words sent a blush through her neck as she turned around and looked at her ass. All the work around the house was practically exercise, and over the past two months she became toned and tan. Her raven-colored hair now stretched past her shoulders and the icy blue eyes sparkled.
Sarah reached toward the counter to pick up a bottle of lube before opening a drawer and pulling out a two-inch wide buttplug. Three weeks ago Uncle Aaron demanded she start practicing for anal and at first, she hated it. The invasive feeling of an object going in her ass was completely foreign, her boyfriend Max had asked a few times to try it, but she always said no. Three weeks in, though, it became just another feeling. A week from now, Aaron claims, she'll be ready to take his cock up her ass, and Sarah couldn't wait for that day—couldn't wait to break another barrier down between the two.
For now, though, she was stuck lubing up the jeweled butt plug and slowly inserting it, feeling her asshole stretch to its limits around the widest point before her hole suctioned off the rest, leaving a bright red jewel at the end. Sarah pulled on some leggings and a sports bra before heading downstairs for breakfast and the rest of the day. Uncle Aaron still forced her to work on the house, "I'm not paying you to be my whore," he always said. Still, if he was feeling extra horny they would take breaks to fuck anywhere in the house.
Today was not one of those days, so time flew by until it was evening. Since it was Tuesday, Sarah needed to go down to town to call her boyfriend—Aaron decided their relationship needed to continue, despite Sarah losing feelings for him about 6 weeks ago. He didn't give an explanation, and Sarah knew not to cross him.
Tonight Uncle Aaron came with her in the old beat-up Ford fusion, he apparently needed some parts from the town. Sarah wore one of Uncle Aaron's old flannel shirts, ditching the sports bra underneath—Sir banned the use of a bra, unless it was needed for work-safety reasons. Sir also wore a shirt, a tight-fitting cotton short sleeve that made his shoulders look broader than a barn, turning Sarah on at the sight of him looking so impressive.
Aaron drove to the town, making it just out of the driveway before gesturing to Sarah to start sucking his cock. She had figured out quite soon that one of Daddy's biggest turn-ons was showing ownership in public, and it became one of her own turn-ons. Two weeks ago, on a drive into town, he'd written "His Whore" across her chest in sharpie, demanding she display it to any car that passed them—at least five cars honked at the pair during the half-hour drive. Today, it was just sucking him off during the drive and now a pro at blowjobs, she made sure to tie her hair before going down on his cock.
They reached the store at 7 pm, an hour before her scheduled call with Max, Uncle Aaron made sure not to cum during the drive, claiming he had something special planned tonight, and when Sarah peeled herself off his cock she saw one person exiting the hardware store, looking into the car with a confused expression. Sarah just winked at him.
"Come on baby, let's buy some supplies," Uncle Aaron said, patting her on the back of the head before exiting the car and waiting for her to meet him at the hood of the Fusion. Taking each others hands, the pair strolled into the store like any other couple—except one 20 years older than the other. It was their fifth time out on the town, acting like a couple and by now Sarah had grown used to the stares. Uncle Aaron seemed more than comfortable in the stares, Sarah noticed their first time out, she doubted this was the first time he'd been with a girl her age. Still, it turned her on beyond imagination that she was her uncle's plaything now.
"What do we need daddy?" Sarah asked, her smile echoing pure joy.
