Dirty Girl

She'd waited all day for this. Squirmed in her seat on the bus, at work, at lunch - any time her thoughts wandered to the evening she was hoping would unfold. And now, it was time. She'd showered, shaving under her arms and her lower legs, but leaving the soft, downy hair of her thighs untouched. She'd taken a trimmer and carefully ran its blade over her vulva, cutting her pubic hair short, and then smothering the area in sweet smelling lotion. She dressed quickly, with a little make up and let her hair dry naturally. She wore no underwear, of course.

Their scene was to begin in just a few minutes, and she sat at the bottom of the stairs almost trembling with excitement and anticipation. He unlocked the door at exactly seven o'clock and stepped inside. Wordlessly, she crawled forward on hands and knees and, as he leaned back against the door, took his soft cock out of his trowsers and began to suckle.

He leant forwards a little, and held onto the back of her head.

"Such a good girl..." he muttered, stroking her hair as she felt him begin to harden in her mouth. He reached down and pulled one of her breasts out of her dress and squeezed it in rhythm with her sucking. Once he was fully hard, he pushed her gently away by the shoulders and walked around to lead her to the curtained lounge.

He sat on the sofa, and patted the seat next to him.

"Hop up, baby girl."

She took a seat, being careful to arrange her dress so her bare thighs and pussy touched the fabric of the settee. She stroked his hard cock lazily as they both settled in.

"Now, today, I'm going to carry on training your bottom. I need to be able to be inside it whenever I feel the urge, so we have to get you ready."

"Yes, uncle." She replied, a slight shudder passing through her.

"You know why we have to have sex this way, don't you?"

"Yes, uncle."

He reached down below the sofa and pulled out a large, plastic box.

"Bottom in the air. Now."

She swivelled around and bent forwards, so her whole body was on the long settee. He let the warm air of the house waft over her for a second, before grabbing a tube of lubricant.

"Hold your cheeks apart."

Her hands went back, leaving her face down and in position as he inspected her tight little hole, brown and puckered. The lube was cold, and she giggled a little as it squirted inside her. He took the smallest plug, and applied lubricant to that, too.

As she felt the tip of the plug press against her bum she took as deep a breath as possible and pushed herself open, quickly taking in the first inch or so. He withdrew it and pushed again, then discarded it quickly.

"It seems you're doing much better than we thought, dirty girl," he said. "Have you perhaps been playing with yourself a little?"

"No, uncle, I swear."

"Well. I want to try something different."

She tensed. "What?"

A quick, hard spank quieted her. She could hear rustling in the plastic tub, and then the order to sit up.

"These should help, as a distraction." He was holding two nipple clamps, each a little weighted, and as she turned he began pulling and tugging at her nipples until they were fully erect. As he closed the clamps sharply over her left breast a small, mewling sound left her throat.

"There, take it girl. Just one more." They hung, pulling her tits downwards in an extremely pleasing fashion. "Now, scoot down and bend your knees. Show that pussy to me."

Once she was fully exposed, lying back with her knees bent and opened wide, he took his newest purchase out of the box. It was a large plug - larger than anything she'd yet worn - but tapered to a very small point. He saw her eyes go wide as he began to lube it up. He placed it at her anus.

"Push out, like you're doing a shit."

She felt the pressure of the rubber against her anus, demanding entry, forced by the strength in his arms. After the first couple of inches were in, the wideness began making her little arsehole sting.

"Uncle, it's starting to hurt."

"I know, baby girl. You can take it."

"I don't think I can, Uncle, God, it hurts."

"Sweetheart, one more complaint from you and you'll have something that really hurts."

He shoved in another inch, feeling her sphincter protest the intrusion, but her eyes were free from tears.

"Breathe through it." He gently pulled out and then pushed in the length he'd already inserted. "You need to be able to take all of this."

She nodded, her thighs clenching. He reached into the box and grabbed a vibrator with his left hand, before applying it to her clit.

"Oh, yes!"

Another inch went in. He smiled to himself, moving the vibe a little as he started to fuck the butt plug in deeper and deeper.

When her arsehole popped closed over the base of the plug, she was ready to come. But that would have to wait. He turned the vibe off, and ignored her pout.

"I want a beer, now. Crawl."

She gingerly sat up, feeling behind herself for the plug he'd just inserted. It felt hard and huge as she moved forward off the sofa, and crawled into the kitchen, nipple clamps swinging with every move. When she returned he was sitting stroking the flogger in his lap, the strips of leather falling softly over his hard, exposed cock.

After several beers, and a few episodes of his favourite TV show, he felt like he'd made her wait long enough.

"Crawl upstairs. I want you bent over the bed." She left a wet patch on the sofa's fabric.

Excitement tingled inside her as she climbed the stairs and situated herself in position. He picked up the flogger and the lube and made sure to step heavily on each stair in turn. He wanted her ready.

His fingers went to her pussy as soon as he reached her, and of course it was soaked, puffy and swollen. The urge to fuck it was very strong, but instead he gave a few short strikes with the flogger, eliciting a low moan from his niece.

As he covered her arse with stripes, he stroked his cock, bringing himself back to full hardness. It would be so good to finally get inside her bottom. When her bum reached a nice, glowing red, he wrapped his fingers around the plug's base and began to pull.

"Push it out, now," he ordered, enjoying the little noises it made and the gasps as her anus could finally relax. There was some gaping, the first he'd seen with her, and he could easily fit a finger inside, but nothing more than that.

He lubed up his cock, wrapped her long hair around his fist, and placed his cock at her arsehole.

"I'm going to fuck your bum now." He saw the clench as her hole tensed, then relaxed. He pressed on, loving the feel of her wet, oily sphincter closing tight on the head of his cock.

For her part, it felt so fucking dirty. She knew her uncle shouldn't even be seeing her naked, let alone putting his penis in her, but he kept her in such a state of arousal with his demands that she couldn't ever find it in herself to say no.

Now he was at least halfway inside. His cock wasn't long, but was so thick and hard, it felt like a ridged, velvet-sheathed glass bottle was forcing itself into her. The pain was worse when he moved, sawing himself in and out and grunting in pleasure.

"Uncle, it hurts," she whined, twisting her hips a little to try and find a less painful angle.

He spanked her left, then right bum cheek hard, and continued fucking her.

"I know it does, my dirty girl, but I have to do this, you know that."

She stayed silent.

"You know why don't you? If I don't put my cock in here, I'll have to put it in your pussy, and you can't get pregnant. The baby wouldn't be right."

"I know, Uncle. It just... it's sore..."

"My poor girl, I know it's sore, but it's your own fault." He let out a deep groan. "Uncle has to do this to you for your own good. You need to be prepared."

Her arse felt like it was on fire as he fucked her hard, pushing her hips into the bed.

"Take it, girl, good girl. Take your Uncle's cock in your little bottom, that's it, girl."

He felt his cum streaming into her arse, as he reached under her, pulling and tugging on her poor, abused boobs, causing her to scream out. He loved hurting her just as he shot his load.

He lay for a second, squashing her into the bed, then as he pulled out, he reached for the plug and pushed it fairly easily back in.

"You will keep my cum inside you for the next four hours."

She whimpered in response. He grabbed the vibrator and a dildo and lay back on the bed.

"Now, you may come if you can fit that dildo in your cunny."

She crawled up the bed and gingerly lay on her back.

As soon as the vibe touched her pussy, her body began to respond again, and the electricity she'd felt earlier returned. The dildo was big, but she persevered and forced the head inside herself. Her uncle watched, spellbound, as she began to hump it.

"Come whenever you're ready. You've earned it. Then you have a two minute break and are to make yourself come again."

As she began to cry out her grabbed her clamps and pulled.

"Come through the pain. Fuck yourself through it."

She squirmed and gritted her teeth as she felt her first orgasm overtake her despite the agony in her tits.

"Yes, Uncle, I'm coming! Thank you!"

It wasn't very intense, but the distraction would decrease as her pain threshold improved.

It was just a matter of time, and she knew this evening wouldn't end any time soon...
