It had been several weeks since Grace had taken Caitlin as her slave. She kept a recording of Caitlin getting fucked multiple times the day she was broken in.
"I will only release this if you tell anyone about what happens between you and me. As long as that's secret, you can live your public life free from the shame of this video," Grace explained.
Grace had been incredibly busy with Caitlin in the following weeks. Caitlin was frequently told to keep a butt plug in her ass or to not wear any panties, regardless of what she wore. It made some days with skirts very hard for her. Sometimes Grace would want more and would keep a remote control vibrator in her new toy's pussy and activate it randomly throughout the day. Grace would laugh and get excited as she watched Caitlin's knees weaken from afar as she hit the magic button that overwhelmed her senses.
However, that was rather tame compared to some of the other things Caitlin did at her command. Grace had put a leash on her one time and walked her around a park on all fours. Caitlin had insisted on wearing a mask in order for her identity to not be revealed and Grace allowed it. She still loved being able to show Caitlin what she now was: her pet.
In addition to these humiliating acts, Caitlin would also get fucked brutally by Grace a few times a week for at least an hour each time. Grace was much less rough than she was that first day, though that's not saying much. Grace never got bored of pounding Caitlin's tight pussy. Sometimes, Grace would treat herself to her favorite; anal. There was nothing she loved more than fucking the shit out of her slave's sweet, perfect bottom until the young blonde beneath her could no longer go on. She saved anal with Caitlin for special occasions though. These always ended with Caitlin's ass turning red.
Caitlin never got used to the way Grace treated her. She'd tried multiple times to erase the recording of her Grace had but got caught (and punished) too many times so she gave up on that. One afternoon, Caitlin refused to show up.
"I can't keep letting her get away with this," she muttered to herself as she returned to her dorm. She thought about Grace maybe releasing the video, but then remembered Grace said she would only release it if Caitlin told anyone, and Grace always kept her word, she knew that much. As long as she kept quiet and forgot the past, she could move on and keep living her life. She wasn't even sure why she had kept going all this time.
She enjoyed a nice relaxing evening of watching TV and soon she forgot about her supposed mistress. At 11PM, she got into a loose Tshirt and pajama bottoms as she went to bed.
She was woken up at 12:30AM when she noticed someone had not only entered her room, but was on top of her. The soft light coming from outside revealed it to be Grace who was already naked.
"Grace, what are you doing?" Caitlin asked, scared but already having an idea of what was about to happen. She hoped desperately she was wrong. "Look, I'm sorry, I'll show up tomorrow to make up for it. Please, I don't-". Her pleading got cut off as Grace slid her hand over her mouth. Caitlin's big, round doe eyes looked at Grace, pleading but they found no mercy.
"Shhhhhhh. I don't know how sorry you are. What I do know, is how sore you will be," Grace whispered. Caitlin's eyes widened in fear. Grace took a red ball gag and some rope out of a bag next to her and placed the gag over Caitlin's mouth.
"Now stay nice and quiet, bitch," she whispered in Caitlin's ear. She flipped Caitlin over so that her ass was facing up and tied her wrists to the bedposts. Caitlin tried struggling but it didn't get anywhere. Caitlin hated her powerlessness and the humiliation of her situation.
Grace knelt so that her butt was resting on the back of Caitlin's knees, pinning her legs to the bed. She ripped the Tshirt off of her tied down victim before slowly pulling Caitlin's pajama bottoms down so that the waist was just below her ass, revealing her smooth, round, heart shaped bottom. Grace watched as it squirmed from side to side, almost hypnotizing in its beauty. Grace took a paddle out from her bag and immediately spanked Caitlin with it. Caitlin jolted in a movement that made it look as if her head had been pulled back and her waist pushed down. She turned to look back at Grace just in time to see her paddle her ass again. Her ass jiggled violently from the impact.
"Time. To. Teach. You. A. Lesson," Grace grunted out as she continued swinging the paddle onto Caitlin's plump bottom. Caitlin buried her head in the bed as tears swelled in her eyes. Her screams were muffled by both the bed and the gag so that no matter how hard she screamed, nothing loud enough actually came out. She increased her squirming trying to get out but eventually realized it only led to harsher punishment. Even in the dim moonlight, it was noticeable that a redness had taken over her formerly pale ass.
Grace then took out a long 10" plastic penis with fake balls attached below it and put it around her waist. To Caitlin's surprise, she moved in front of her face instead of behind her. She slapped Caitlin's cheek with the plastic cock before undoing the ball gag. Before Caitlin could get either a plea or a scream out, Grace rammed it down her throat. Caitlin gagged heavily. Grace ignored it, grabbed the back of Caitlin's head and pushed it down to the base of her dildo. Caitlin's eye twitched and drool was falling from her mouth as the dildo reached deep in her throat. Grace then ripped it back out, causing Caitlin to cough before Grace put the gag back in.
"There, now it's nice and lubed up," she said as she walked behind her and took her place behind Caitlin.
Caitlin was all too familiar with what was about to happen next so she looked straight ahead, ignored her tears and prepared for what she knew was coming. Grace rested the fat dildo on Caitlin's back, letting her feel both its presence and her own spit dripping off it. What Caitlin hadn't expected was something being wrapped around her neck.
She couldn't believe it, Grace had just leashed her. Grace pulled Caitlin's waist up, so that Caitlin was on her knees. Caitlin propped herself up on her hands as Grace gripped each of her ass cheeks. They felt so soft in her hands as spread them far apart to get a good view of her target. The dildo looked almost shiny in the moonlight due to the intense amount of Caitlin's throatslop that covered it. She lined it up with Caitlin's ass and slowly put it in until she got the head in. The pressure felt like it was going to kill Caitlin and the wetness of her own spit felt gross against her bare ass but before she could worry about it, Grace crammed the whole thing in as fast as she could. It took more effort than she thought it would, but she did it. She was surprised at how tight Caitlin always was, as if the weeks of fucking hadn't affected her body at all.
However, this meant that it hurt a lot for Caitlin, she could feel her own spit getting her insides wet as the head rubbed against her inside and spread her wider than she was ever meant to be spread.
"How the hell are you still this tight?" Grace wondered out loud. Then leaning in behind Caitlin's ear she whispered, "I'm not complaining though. It just means I can break you in over and over." Caitlin whimpered softly.
Next Grace grabbed the leash around Caitlin's neck with her right hand and started pulling it back every time she was about to thrust forward. Caitlin would be jolted forward by the thrust only to be pulled back by the leash. Caitlin's ass bounced back to meet the waist of its mistress as she got fucked at a pace unlike anything had ever fucked her like before.
"You are a piece of fuckmeat, here for my pleasure above all else," Grace grunted at her. Her movements were quick as she rapidly thrusted in and out like a piston but with enough weight behind each one that Caitlin felt like a sledge hammer was hitting her stomach inside. She felt like she was being pushed and pulled in every possible direction in addition to the dildo up her ass making her feel like she was being split in half.
Grace viewed the long, blonde hair bouncing and the rippling of Caitlin's ass as almost artistic in the moonlight but didn't let that (or the muffled screams) slow her down. Caitlin felt more pain than usual as Grace's waist bucked against her ass, still incredibly sore from the paddle. She gagged but was unable to actually get much noise out due to the actual ball gag in her mouth.
