Here is the background. This is a fictional story.
**Kate**: *F23. Main female of the story. 5’5″, b cup, slender, perfect ass. Feisty, irritable, playful at times, defensive, sexy, vanilla with subpar past sexual partners. Jen’s slightly older sister.*
**Jack**: *M25. Main male of the story. 6’0″, athletic, womanizer-type, suave, confident, amazing lover*
**Jen**: *F22. Kate’s younger sister. 5’6″, c cup, slender, not as good as Kate’s ass. Typical, slutty, yet romanticizes too much.*
**Setting**: *Kate’s apartment*
——————————————————————————————————————————–
He tossed Kate’s shorts back to the floor, damp and soaked now after he used them as a makeshift rag to wipe down Kate’s legs and his own cum that was leaking out of her pussy as she slept peacefully. He stroked her beautiful brown hair gently with his right hand as he had laid her down with her head against her pillow and curled her legs up for her. He took a moment to admire her beauty, the light freckles on her face above her cheeks and how adorable she looked as she slept.
Having already fully dressed himself by this point, he walked over to her window and looked out of it wondering if he should proceed with his new plan or not, fiddling with something in his pocket as he stared out idly at the horizon.
***She has a much better ass than Jen, there’s no question, and she’s so mouthy. She would certainly keep things interesting. Plus, Jen has become too obedient and predictable.***
Jack’s train of thought was interrupted as he heard the soft stirring of Kate, who was coming to out of her slumber. There being no other noise in the bedroom, it was easy for him to hear her.
Kate awoke and gently opened her eyes to face her wall and her nightstand.
***That was some dream…***
She suddenly felt a draft of cooler air whisk past her legs and her pussy, sore from the primal pussy pounding that she had received not too long ago. She wondered where her underwear and shorts were as she normally didn’t sleep nude or above the covers. She reached between her legs and felt traces of cum left on her inner thighs from the cum that Jack had left in her. It suddenly dawned on her that the whirlwind of an afternoon that she had really did happen and wasn’t some crazy fantasy dream.
She lifted her head up and looked behind her, leaving her body curled up as she was still comfortable. She noticed Jack standing stoically and looking out of her window with his back to her. She turned her head back around, her back to him still, and reached down at her shirt, holding it gently and remembering not wearing one before she fell asleep.
She was irritated by his stature as she regarded that he likely considered that he had ‘conquered’ her, and with ease. None of this was part of her original plan to get Jen out of harm’s way. She then began to think about her clothing situation.
***Huh…he must have dressed me. Looks like he put minimal effort in though…ugh…unless he just wanted me only wearing a tee.***
She wanted him to leave and for him to be out of both her and her sister’s lives for good now. However, a part of her couldn’t help but think back on the experience with Jack.
***That was so amazing and intimate. Ugh…what was I even doing with all those other guys before him?***
Her mind flashed back to before he carried her to the bedroom.
***Why did his ultimatum and counting work on me? I felt so…***
Her mind raced again to different points during the sex to when he used that authoritative tone with her.
***I’ve never let someone control me like that, but why did it feel so…..and why did it make me so wet…UGH….what is it about this guy?***
Forgetting that Jack was still in the room, she laid her head back down on her pillow where Jack laid her and clutched the pillow with both of her hands, pondering on the situation.
***Stop thinking about it, Kate. It doesn’t even matter anymore because the deal is done.***
Against her own inner voice, Kate started to reflect more on the situation as she tried to get some more rest, feeling very comfortable on the bed. She couldn’t believe how easily he had forced her to cum and how many times he made her do it, all while holding off from cumming himself until he had left her as a wet, exhausted mess. Jack’s power over her irritated her greatly. How could she have reduced herself to being a slut for him, even if it was only once. She would never forget, even if he did in time, eventually.
Jack walked over quietly to the edge of Kate’s bed, noticing that she was deep in thought and didn’t even notice him. He caught another glimpse of her swollen pussy lips as she was curled up in full view of him. He gazed at her with his hands on his hips.
Jack started, “Finally awake? I told you that you would be very happy…or at least very pleasured, kitten.”
He noted that pounding her into submission and exhaustion had made her calm and more docile as she did not hiss back at him this time. He liked seeing himself as the only one who could pacify her and leave her sexually satisfied as he was sure that she had never experienced anything like that afternoon before.
Kate, enraged, but exercising restraint, let go of being called a ‘kitten’ by him, but mostly because she didn’t have the energy to spare to argue with him again.
***Kitten…? KITTEN??? Did he just call me kitten?***
Jack realized that she was rather simply too tired now to fight instead of being submissive to him as he saw the pouty look on her face when he called her by the pet name. Her response confirmed to him that she would make things very interesting going forward, so he decided to pursue the new course of action that he thought about earlier before Kate awoke.
He reached into his pocket and pulled out a light pink choker with a metallic heart cut-out in the middle. Originally having planned to give it to Jen, he found her replacement, Kate, to be far more suitable to wear it. Jack ran his fingers gently underneath the toes of her right foot and held up the choker for Kate to see. He rattled it like a toy to get her attention. She lifted her head up from her pillow to look up at him and then retracted her foot from his touch, even though she actually liked it.
She made eye contact with Jack, who smirked at her, and then she turned her attention to the choker in his hand that he held up for her. She went wide eyed and blushed immediately before firing a piercing glance back at him.
“Put it on.” Jack said in a calm authoritative tone.
Flustered and confused, Kate lashed out at him, “Asshole, that’s basically a dog collar! I’m not wearing that…I’m not a dog!”
She couldn’t take her eyes off of the choker, thinking to herself that she would absolutely just die if someone saw her in that. Kate was more of your good girl-type, respectable and modest.
***What is he? Insane? Anyone who knows me would know that if they saw me wearing a collar like that it was clearly because I was someone’s slut or into kinky sex. He might as well be calling me his…his….sex kitten…UGH***
“No, you’re not” he retorted, “but you’re mine now.” He replied calmly.
His calming voice sent alarm bells ringing in Kate’s head and raised a bit of a panic in her as she sensed that he said it at though it was guaranteed to happen. Before this, she felt that they were just two adults on the same level having some wild sex, but now, she started to feel a strong sense of possession from Jack towards her. She felt like she bit off more than she could chew or stirred the hornet’s nest, so to speak. Her curiosity of it all excited her a bit though, but she was a bit timid and afraid of what had just transpired.
Regaining some of her confidence, she sat up, kneeling on the bed now near her pillow and stared at him coldly as he wagged it at her like a toy.
“I’m not your….kitten, your babe, your slut….your anything.” Kate protested sternly, but somewhat calmly trying to avoid agitating him.
“Actually, you’re all that to me…and more.” Jack said a bit more forcefully now.
Pleading with desperation in her voice now, she fired back, “This was not part of our deal, Jack! I never agreed to model your kinky sex jewelry before you gave them to your other girls! I only did what I did to get you away from Jen and it was a one-time thing!”
Jack noted that she indirectly called herself one of his girls. Kate, still on her knees, crawled towards the edge of the bed to be closer to him.
He responded, “No, if you recall, we didn’t shake on anything.”
Using his left hand, he reached out and gently rubbed under her chin.
“Don’t tell me that you didn’t enjoy it when I made your kitty purr for me. I’ll be making you do it again real soon, kitten.” Jack said confidently.
Kate pulled her face away from his hand in a delayed response, her face completely red now as she thought about his insinuation that she’s his kitten. She started to feel moist again just thinking about it as the images of her being forced to cum flashed in her head. She tried snapped out of it somewhat before things got out of hand. Clearly, Jack must have misunderstood somewhere along the way.
She looked down at the floor and tried to think back to an hour ago before the incredible sex, and then remembered extending her hand out to shake, but was greeted with a firm kiss on the lips instead before everything else just happened. Thinking the worst, her thoughts raced again.
***Wait, this bastard! He got to pound me so much and he’s still going to keep seeing Jen. How could I be so stupid?***
As she started to look back up at him, she felt his left hand wrap underneath her tee and around her bare left butt cheek, catching her off guard entirely. Jack latched onto her cheek and scooped her up a bit and pulled her in close to him, setting her back on her knees on the bed, but with his hand securely fastened on her butt. She couldn’t admit it to him, but the warm skin-to-skin contact felt so good to her, and so did the physical aspect of him manhandling her like that. Good enough to keep her from reacting quickly enough to be a natural reflex. Not wanting to totally submit to him, she became defensive and put her hands up against his chest to press off of him a bit to keep her face away from him, but was unable to get free from his grip below.
Jack lightly spanked Kate, but sternly, for her squirming around, which created an audible skin-to-skin contact noise that made her stop. He used with the same hand that he was using to hold her butt, and then firmly latched it back on to hold her cheek.
“Ugh…what are you doing? Our deal is done. Get your hand off of my butt.” Kate said unconvincingly.
Jack commanded her gently like a parent disciplining a child, “Kate. Put it on.”
With that, he squeezed her butt cheek as he brought the choker closer to her face. Not wanting to give him any satisfaction or to give him any positive feedback on his methods (though she was without knowing), she kept herself from squealing in response to the squeeze. She didn’t realize it, but that lack of a response indicated to Jack that she was fine with it as well.
She melted again as he used that tone with her as she looked him in the eyes, and stopped pressing against his chest in an effort to push away. She started feeling like a little girl who would otherwise get in trouble if she disobeyed him.
She rolled her eyes, sighed, and angrily grabbed it from his hand, removing both her hands from his chest as she found herself secure from falling from the bed with him holding her. She reluctantly put it on after moving her brown hair out of the way and then flipped her hair back to normal. Her own thoughts started to become hostile to her in a defensive manner.
***Kate. Moron! What are you doing? Stop thinking with your pussy and start thinking with your head!***
With her arms crossed now, Kate gave him a fake smile and asked “Happy now, asshole?”
Jack released her butt cheek and moved a finger between her cheeks, closer to her asshole until he gently landed on it, circling his finger on it from underneath the shirt.
“Stay.” Jack commanded softly, but sternly, knowing that she would probably not take it well.
Kate gasped audibly and let out a slight yelp while she blushed hard, mouth agape, and quickly placed her hands on against his chest again as a legitimate reflex, unable to hide her response as she had never had any anal attention before and wasn’t expecting it. Jack had a full view of and handfuls of Kate’s butt throughout their afternoon together, but he never made a move on her hole, even when his face was inches from it when he went down on her, leaving Kate to think that it wasn’t a factor. Even then, she attempted to maintain her composure and didn’t squirm much.
“Good girl.” Jack whispered to encourage her.
He noticed that Kate was genuinely shocked by his action, but had tempered her response to it as she was so strangely turned on by it to her own surprise.
“It (choker) looks cute on you and is a perfect fit. By the way, Jen never got one and none of the other girls have one…at the moment.”
She was taken aback at first, but found his continuous massaging of her asshole a strange combination of being both embarrassing and calming. Simultaneously, he took his right hand and gently tugged on her collar to show her the snugness of it, bringing her face closer to his.
“If you keep being good for me, you’ll get more rewards. What was that you called me earlier?….Asshole?”
Kate gulped having realized that like her feet on the sofa, she might have been responsible for giving him ideas.
“Interesting, an asshole meets an asshole (he intensified the finger massage). If you were trying to be suggestive with that word, kitten, it worked. Also, don’t worry. You succeeded…I won’t be seeing Jen anymore.” Jack said smugly.
He knew that he had found the perfect replacement in Kate. Her pussy was throbbing and her body was heating up. It was just all too much.
He used his massaging finger to tap her hole lightly a few times. Each tap from his finger to her asshole caused their eye contact to be even more awkward for Kate as she became even redder than before, clearly unsure of how to respond.
He stole a quick kiss from her and reluctantly pulled his finger away from her asshole, letting his hand run across her lower back as he pulled it from under her shirt entirely. He turned towards the door to leave. Kate began to lose her balance without Jack there to hold her, but caught herself, annoyed that he left her like that without warning. However, she used it as an opportunity to create some space between her and Jack to breathe normally again. Everything happened so quickly and she was still trying to make sense of it.
***What a minute. What the hell just happened? What did he even mean by ‘keep being good’?***
Gathering her thoughts quickly before he left, she called out to him and scoffed nervously, “Wa…wait! What does this even mean?”
She grabbed her own collar and looked at him, confused, completely humiliated, but somehow somewhat excited.
He stopped at the door and turned. He looked at her and said, “Still don’t get it, Kate? You made a trade. I’ll stop seeing Jen as you asked, but you’re taking her place. Now, whenever I see you, you better have that choker on for me.”
He walked out of the bedroom and then also out of her apartment as Kate sunk down from kneeling and eventually laid herself back down on her back.
Completely confused, baffled, and yet fully sexually satisfied and then some, she wondered if she made the right decision to keep her sister from this womanizer or if she ended up keeping him for herself. More importantly, how would her sister look at it if she ever found out? She would just think that she stole her sister’s boyfriend. She reached up and grabbed the choker again, trying to get used to the feeling. As much as she hated to admit it, she couldn’t go back to her vanilla boyfriends of the past or other guys like them. Jack had awakened something in Kate. Though she wasn’t completely submissive yet, she found the feeling of being submissive alluring and exciting.
“Ugh…that..that…jerk!” Kate bellowed to an empty room.
Since no one else was around, she shyly reached down between her legs to reach her asshole, not quite able to massage it like Jack did nor able to generate the effect that he did on her. She pulled her finger away, feeling naughty for even trying.
***Kate….what have you gotten yourself into?***
