Kathryn hissed on the large, satin sheeted bed as Cecile ran her hot, wet tongue over her equally warm and wet pussy. She ran her fingers through the young girls silky brunette hair and inhaled as it released the intoxicating aroma of her sweet orange blossom shampoo. Cecile felt good but she was no expert of course. Kathryn had her under the impression that she needed to be prepared for anything when it came to sex, how else would she impress Ronald and keep him happy, she had said to her. After coaxing Sebastian into fucking her a few times, Kathryn thought taking advantage of the poor girl herself was too good of an opportunity to pass up. She had many male play things after all but the female ones were a little more difficult to come by. She hadn't anticipated that Cecile would actually fall for her the way she had. Cecile would never admit it of course but it was all too obvious to Kathryn and she was also aware that she could use it to her advantage, given that Cecile hung on every word she said, blinded by lust. Kathryn wondered what Court Reynolds would think of this innocent little twit now if he knew she was becoming quite the slut.

"I have a little challenge for you." Kathryn said bluntly as she pulled Cecile's head from between her legs and sat up to face her. "Have you heard of Annette Hargrove?" Kathryn asked.

"She is the new headmasters daughter isn't she?" Cecile replied, wiping Kathryn's wetness from the corners of her mouth.

"Yes, I'm afraid she's not what you would expect from a headmasters daughter either." Kathryn said with a false coy look.

"What do you mean?" Cecile asked.

"Well, I wasn't quite sure how to tell you but Annette has been getting acquainted with Ronald, a little too well acquainted." She hinted. Cecile being the complete imbecile that she was had no idea what Kathryn was insinuating, as was perfectly clear by the vacant expression on her pretty little face. "She's trying to fuck him." Kathryn said with a lack of patience.

"But isn't she supposed to be like, some sort of super virgin?" Cecile asked confused.

"That's what she'd have everyone believe but as I told you Cecile, everyone fucks around, they just don't talk about it." Kathryn reminded her.

Cecile's eyes flashed with anger. She stood up off the bed and started to pace. The first part of Kathryn's plan was working.

"I'm doing all of this for Ronald!" Cecile raged. "Surely he wouldn't let her fuck him even if she offered right?! He loves me!" She yelled.

"You love him too don't you? yet here you are eating me out and taking it off Sebastian every week. Besides men are week Cecile, even if by some bizarre twist of fate Ronald was monogamous, he would never be able to resist the temptation. Have you seen the girl? She has an ass to die for and tits that could tempt any hands." Kathryn really drove it home.

Eventually, when her jealousy and frustration had reached a peek. Cecile stopped pacing and turned to face Kathryn, who was lay patiently waiting and watching the carnage of the poor girls inner turmoil play out perfectly before her.

"So what is your challenge?" She finally asked.

A sadistic grin slowly crept across Kathryn's face. She knelt up and moved toward Cecile, cupping her hand by the side of her own mouth, she prepared to whisper into Cecile's ear.

"I want you to fuck Annette Hargrove and provide me with proof of it."

Cecile stood back in shock. She appeared horrified at first but then a small look of excitement crossed her face, only to return to horror again in an instant. Kathryn smiled impishly at her and got comfortable on the bed again.

"So, I get the fucking part but how do I get proof?" Cecile asked.

"Oh I don't know, be creative. Video it, get her to write a letter, record her phone calls, anything!" Kathryn told her. God this girl was a moron.

"Oh right, ok, yeah." She complied. Cecile turned to walk out of the room but Kathryn called her back.

"Um, where do you think you're going?" She chimed.

"Erm, to try and fuck Annette, duh." Cecile pulled a face at Kathryn. Kathryn shook her head and motioned with her index finger for Cecile to come back to the bed.

"We haven't finished your instruction for today yet." She said seductively.

Cecile shrugged and eagerly climbed back onto the bed, crawling up towards Kathryn. Kathryn spread her legs apart and lay back.

"Carry on where you left off." She instructed.

Cecile did as she bid. Gliding her tongue over Kathryn's dripping wet hole and then her clit in turn. Soft sounds of pleasure escaped her but Kathryn was no where near getting exactly what she wanted. That had to change, this girl would make her cum before she threw her out, she would make sure of it.

"Put your fingers in." Kathryn ordered. "One at a time and make sure you flick my clit with your tongue." She breathed heavily.

Cecile did exactly as she was told. Sliding one finger in and out as she flicked at Kathryn's sensitive little clit with her tongue. Finally she added another finger and flicked at her faster. Kathryn moaned and ground her hips into Cecile's fingers.

"Faster." Kathryn forced in frustration.

Cecile began pounding her fingers in and out of her rapidly, sucking gently on her now highly sensitised nub. Kathryn was impressed with Cecile's sudden improvisation and while she was almost there, she wasn't yet finished with her.

"Put a finger in my ass." Kathryn breathed.

Cecile acted immediately, shoving one of her other fingers into Kathryn's ass and wiggling it wildly. Kathryn moaned louder and louder, finally falling over the edge and coming all over Cecile's hand and face. Kathryn was actually quite impressed, she hadn't expected that the inexperienced little bitch would be able to get her to come that quickly. Maybe she was an even better teacher than she had given herself credit for, Kathryn thought proudly. She couldn't let Cecile know that though.

"Good Cecile." Kathryn panted as she handed her her jacket and pointed towards the door. "Not great but good. We will keep practicing. Off you go." Kathryn said with an air of nonchalance. The young girl took her jacket and headed for the door, her head hung low. Kathryn knew that she craved reassurance and reward, which was exactly why she didn't give it to her. It was just far too much fun to watch Cecile doubt herself.

Later, as Kathryn sat filing her nails and watching the maid go through her wardrobe, telling her what to keep and what to throw out. Sebastian made an appearance. He strolled into the room with his usual confidence and playful look.

"Evening sis." He said as he walked over to her.

Kathryn couldn't help but notice the way the maid tensed and coward behind a garment when she became aware of his presence. Sebastian noticed it too, he shot the young Hispanic beauty a toothy grin and winked at her, licking his lips suggestively. The girl tried fruitlessly to look anywhere else but at him, almost shaking and with a pained face.

"I... I'm sorry Miss Kathryn, p..please excuse me." She stuttered as she ran from the room.

Kathryn shot Sebastian a look to kill. He merely smirked at her and shrugged.

"How many times Sebastian? Stop diddling the maids. Good help is hard to come by these days. Who do you think you are? Your father?" Kathryn hissed with venom in her words.

"The horny little Chica was bending over in front of me all the time. She wanted it just as much as I did. Just because it turned out she didn't like it in her ass after all, that's not my fault." Sebastian defended himself.

Kathryn rolled her eyes at him and sighed.

"Whatever." She rushed. "Why are you here Sebastian?"

"Do I really need a reason to come visiting my adoring Step Sister?" He asked, standing behind her, massaging her shoulders.

"No, yet I'm sure you do." She said expectantly.

"You know me too well." He responded.

"We know each other too well." She said darkly as she peered up at him.

"I've been thinking about our little conversation yesterday." He started.

"And?" Kathryn asked.

"And how serious were you about letting me fuck you?" He probed.

"Very" she insisted, her eyes studying him wantonly.

It was true. Kathryn had wanted a piece of Sebastian's cock for as long as he had wanted her but for whatever reason she had found the idea of wanting him much more erotic than actually having him. Now that it was looking as if little miss Kansas City might actually succeed in taking Sebastian away from her, Kathryn's territorial nature and competitive tendencies took centre stage. She became even more aware of Sebastian's raw sex appeal. His hot breath on her neck when he spoke his dirty, teasing thoughts to her. His perfectly toned body as it crushed against her when they were being playful and his hooded eyes when he walked in on her fucking random guys once or twice. She was indeed serious about them finally fucking but she had her conditions, as always.

Sebastian leant down and kissed a sweet spot just below her ear. His hand slid down to grope her breast, she gasped.

"Then what are we waiting for?" He whispered into her ear. The vibration of his voice and heat of his breath sent an electric spark all the way down her body, ending up deep inside her pussy, getting her wet almost instantly. As if he knew, Sebastian moved his hand lower and under her skirt. He slid her underwear to one side and rolled his fingertip over her tight little opening.

"What about Annette?" Kathryn moaned.

"I will deal with that later." Sebastian told her.

Kathryn waited until one of the recurring waves of pleasure subsided before grabbing hold of Sebastian's hand and pulling it out from under her skirt. She stood up abruptly and walked to the window, gazing out at the street below as she spoke.

"Nothing is going to happen between us until that blonde little daddy's girl is out of the picture, do you understand? I'm nobodies stand in Sebastian you know that." She told him coldly.

She did not make eye contact with him but she felt his eyes burning into the back of her. Neither moved an inch but both were frowning.

"And what makes you think I'm going to give her up just like that? Just for the sake of one night with you? How do I even know you will keep your word?" He scorned.

"Like I said Sebastian, we know each other too well, you can answer those questions yourself." She said whipping her head around to scowl at him.

Sebastian made a frustrated growl, slammed his fist onto the back of the chair he was leaning on and stormed out of the room. Kathryn smiled.
