STORY SO FAR: Grace enslaved 3 girls; Caitlin, Brenna and Sophia. Then, one night, she and her friend, Zoe, were fucking them, they fought back and overpowered their two rapists, proceeding to fuck them in return. They let Zoe go but Grace they took to a frat house, led by Matt, to be THEIR slave. The frat house agreed on the condition that Caitlin, Sophia and Brenna "entertain" their party guests. After getting choked out during sex, Caitlin awakes in the morning with her head on Grace's lap.
--------------------------------------------------------------------------------------------------------
"Rise and shine, blondie," Grace said in a sing-songy voice. Caitlin was still trying to process everything, but the sound of Grace's voice made her lurch up. Caitlin noticed that Grace was still naked too, so she probably had not left the frat house yet. All of Caitlin's memories of the night before came flooding back alongside the soreness in her bottom. "Matty, can you give me a minute alone with my little bitch?" she asked him sweetly.
"Of course." Matt got up and left the room, leaving Caitlin by herself, looking up into Grace's twisted eyes.
"Matty and I were talking, and we came to a nice little agreement that I think you are going to LOVE!" she continued, looking down at Caitlin, gently caressing her face. Caitlin was too scared to move. "Basically, I told him that I owned the three of you and that I'd trade myself for you three! Now normally, they wouldn't go back on a deal, but they owe me for letting them have a few slaves I'd lost interest in a couple years ago, so it wasn't that hard to convince them. Wish they'd bargained with me sooner. Just like you, my bottom is quite sore. Don't worry though, I'll buy you back. I just need to...prepare a few things first," she said, clearly thinking hard about how to phrase the last sentence.
Caitlin immediately took off running. She forgot about any soreness and just knew that she had to leave as soon as possible. She saw a window and headed for that. Luckily, they were on the first floor.
She didn't even make it halfway before Grace tackled her from behind, sending her crashing down to the floor, face down. Grace pinned Caitlin to the ground by her shoulders and knelt on her thighs. Caitlin thrashed as much as she could, but it was to no avail. As usual, Grace was just bigger and stronger. Caitlin was prey and Grace was her predator. There did not ever seem to be anything she could do to stop her. Grace brought her palm down on Caitlin's supple behind. "Do. Not. Try. To. Run. From Me," she said each word between spanks.
After the series of vicious blows on Caitlin's bubbly backside, Grace pushed her fingers into Caitlin's well used asshole. Caitlin let out a scream as she felt the surprise invasion of her hole. Grace was only making the memories of the night before even clearer in her mind. "I just wanted to check how much fun you had at the party last night. Seems like they put you to pretty good use," Grace giggled as she felt the really sore walls of her sphincter. She flicked Caitlin's inner walls upon finishing her sense.
Grace held Caitlin down with one arm as she pillaged her favorite fuckhole, her hand balled completely inside her as she rapidly fucked her hand in short movements inside her asshole. Grace wiggled her wrist as fast as she could imitating a vibrator as she forced Caitlin to cum. Caitlin shook and jiggled violently under her.
"God, I will never get tired this ass and those screams," Grace said as she popped her balled up hand from Caitlin's gaping asshole. "But before I leave, I just want to say that, before you were out cold for over 12 hours, you were pleasuring guests until 3 in the morning! I am impressed, and SO proud," she stroked her fingers, fresh out of Caitlin's ass, along Caitlin's face as she said this. "Looks like they really couldn't get enough of this huge butt of yours," she said, moving her hands to grab two handfuls of Caitlin's "huge butt" and playing with them, shaking them around.
"I can't blame them. I want to do so much more to it right now. You're soooooooooo lucky I don't have my toys with me," she continued. Caitlin felt Grace getting wet. "Although, you're probably so familiar with them by now that I don't even need them." Caitlin felt her mistress slam her hips against her butt, as if Grace were imagining that she had a dildo to slide into her. "Just try to feel me cracking your big butt open nice and wide, stretching you out. There's no escaping it."
Caitlin had so many vivid memories of getting fucked by Grace that she actually felt like she was being penetrated.
"Can you feel it tickling the inner walls of your ass? Just picture the sensation as I push it in and drag it out. I am filling every inch of you," Grace whispered softly into Caitlin's ear as she moved her pelvis back. She started moving her hips more quickly, repeatedly impacting Caitlin's butt.
Caitlin could no longer tell if she felt the soreness from last night or if it was all caused by Grace. She was short on breath and slowly losing grip on reality.
"No, you're not. No, you're not. No, you're not. No, you're not," Caitlin whispered quickly, her voice shaking. She was trying to convince herself that she was not imagining any sensation caused by Grace.
Grace leaned in and whispered in her ear, "You looked SO hot last night. I saw pictures of you in your cute little shorts and oh my GOSH did I just want to devour you whole! I don't even want to tell you about the night I had. I am so heartbroken that I was too busy with Matt and some other boys all night to spend any time with you. That really was the worst part of the whole night. But like I said, I'll buy you back as soon as I can. Luckily, there were plenty of videos and photos taken. When I woke up this morning, I fingered myself to your little dance routine. You should dance for me more often. And Zoe had a great video where she choked you between her thighs. It looked like you were getting utterly DEMOLISHED on the other end. Girls who cry are SO hot. I bet you can still feel it now. I wish I'd thought of making money off of you 3. That was a stroke of genius."
Grace rambled on and on about Caitlin's performances last night. Caitlin could feel Grace's vaginal fluids getting smeared on her ass as she thrusted more excitedly. The feeling felt so real, it actually brought Caitlin to orgasm. Satisfied with the mental state of her favorite bitch, Grace just stopped. "Oh blondie, I have something wonderful planned for you when you finish your time here so look forward to it," she said before sauntering off. Caitlin saw her kiss Matt when she exited.
Matt came in and Caitlin picked herself up off the ground. "Sounds like you two had some real fun in here," he said. "I imagine she told you about your new situation and I won't beat around the bush here. You are our sex slave. Typically, after a while, we'll sell them off to other people but sometimes we keep them around for a long time. Apparently, way back in the day, they kidnapped some poor girl and kept her for so long she went from smoking hot college babe to a MILF. Rumor has it she grew to like the slave life and they let her go free without ratting anyone out. Nobody here is sure, this happened decades ago. With any luck, that'll happen to you, I can imagine Omega Nu kids gathering round to fuck you for years. Unfortunately, though, Grace looked excited about buying you back and that was one of the conditions of this agreement. She can buy any of you back at any time for the normal price we would sell you at. Anyway, let's reunite you with the other two girls."
Matt whistled and Brenna and Sophia were escorted in. "OK, so first order of business, you guys have new uniforms."
He pulled out a bright pink bra and black booty shorts and tossed one to each of the girls. The bras each had a black Omega on the right breast and a black Nu on the left. The booty shorts read "PROPERTY OF OMEGA NU" in pink writing on the front. "If you look at the back, you'll each find your brand-new nicknames," Matt explained.
Caitlin looked at the back of hers and saw the words "BUTT SLUT". She looked over to see Brenna and Sophia's and saw that Brenna had gotten "MS. MELONS" and Sophia had gotten ''COWGIRL".
