She shoved the green dildo into her pussy quickly enough to make it uncomfortable, but she didn’t want to stall. Her master always asked for a show. The fact that he specifically instructed her otherwise tonight didn’t bode well for her. She straightened up as soon as she was able to and scampered to stand in front of the camera.
He admired his prize. The small blonde girl was a wonderful example of youthful beauty, but that wasn’t what he loved about her. What excited him more than her body was the moment. This moment, where she stood nervously, waiting for her next instructions. He decided to give her a small break.
“Your pussy is full, your ass is clean, and Casper is here. Do you know what’s going to happen?” her master asked his tone seemingly curious. If Stacie didn’t know him so well, she might have actually suffered a hope of being able to escape this night with only as much shame as she’d already gone through.
“Yes, sir,” she replied, fighting not to look away.
“Do you want it?” he asked then.
Stacie almost replied yes, but remembered why she was in this position in the first place. “No, I don’t, sir.”
He smiled at her. She’d passed that test, but it didn’t change much. “Will you take it?”
“Yes, sir.” Her answer was automatic, without any hesitancy.
“Why?”
At this, she faltered. She knew the reason like she knew herself. The words were difficult, though. “B-because… You’re… I’m… I’m yours, Master. I’ll do whatever you want.”
He could hear the honesty in her voice, but he wasn’t going to let her off so easily. “So you’ll obey my rules?” he asked.
“Yes, sir.”
“Only cum when I tell you to?”
Stacie nodded emphatically. “Yes, sir.”
“Not LIE to me?”
Stacie’s knees almost buckled. His tone was so strong that it had physically jarred her. “Yes, sir.”
He stared hard at her for another minute before speaking again. “Since you’re going to take it anyway, you might as well ask for it,” he said.
Stacie relaxed a bit. He didn’t seem angry anymore. “That’s right, sir,” she said, actually glad to be back on this subject. “May I have Casper fuck my ass, sir?”
His smile grew. “Oh, no, my pet. You can do better than that.”
She nodded slowly and got down on her knees. “May I please have Casper fuck my ass, Master?”
The puppy dog eyes were a nice touch, he thought to himself. But… “Patience. You need to get ready first. Lube your ass and make sure he’s wet.”
“Yes, sir. Thank you, sir.” She walked back to the box and, sure enough, Casper followed right behind her. He didn’t like it when she made him wait. While she was squirting lube into her hand, he was starting to nip at her thighs- not trying to hurt her, of course, but still making it clear that he was getting impatient.
She pushed him down and dropped down to her knees. ‘Make sure he’s wet’ could only mean one thing. The hand that had the lube on it reached behind her thoroughly slick her asshole. The other reached out for his cock. She then slowly leaned forward until she was propping herself up with her elbow, and took it into her mouth.
It wasn’t the first time she’d done this. Almost immediately after Stacie had lost her virginity, her master had suggested- as if anything that he said was merely a suggestion- that she learn how to give a blowjob. Since then, she’d swallowed quite a lot of cum, so she was led to assume that her technique was pretty good.
Tonight, however, the point was to simply get him wet, so she was fairly sloppy compared to her normal method. Besides that, the only thing that she had to worry about was keeping Casper from getting too excited. If he came or even knotted before he was inside of her, she’d surely be punished for it. Concentrating was just a little difficult, though. She could almost convince herself that sticking her lubed finger in her ass felt good.
“That should be enough,” her master said, causing her to look up briefly. Only briefly, though. She didn’t even need prompting for this next part. She got on all fours and offered her ass to her dog. He never needed prompting. He mounted her without hesitating.
For a few agonizing seconds, he thrusted aimlessly at her backside, even hitting her dildo a few times. But when he finally entered her ass, her master was able to tell immediately by the way that her face contorted in discomfort.
“How is it?” he asked, his calm voice a strange kind of counter to the jackhammer thrusts that Casper was using.
“It… hurts, sir,” Stacie choked out.
“Do you feel full?”
“Yes, sir.”
“How full?”
“So, so full… ugh… Master…”
“Personally, I think that the dildo was a nice touch. I’d thought of several other methods that could have kept him from going in the wrong- sorry, the ‘right’ hole, you know. Do you know why I didn’t choose any of them?”
Stacie was barely able to even understand what he was saying at that point. In the middle of his speech, Casper had begun knotting inside of her, so all that she to get out in response was in the form of grunts and moans.
“I can tell you’ve got a lot on your mind at the moment, so I’ll excuse your rudeness in not replying and just tell you. It was so that you could get the experience of being dee-peed- that’s double-penetrated, in case you didn’t know. I’d assume you do, but then, it’s foolhardy to make assumptions.”
Her processing ability was nearly gone at that point. The pain, if she even claim to continue calling it that, had almost completely overtaken her. Her body was treating everything as pure sensation, broken only by the still-present attachment to her master.
“I do hope you appreciate it,” he continued. “I considered using a rabbit- one that stimulates your clitoris too- but you and I both know that I can only be so kind. If I only had you to do things that you enjoyed, I’d be a bad owner, now wouldn’t I? It would just be spoiling you, and it would be no different than if I let you be on your own. And I’m sure by now you can be appreciative of hav-”
“Master,” Stacie gasped. “Cum.” If she had been in more control of herself, she might have felt shame at being driven to orgasm, but for the moment, all that she wanted was release.
He hated making things easy for her. “You’re going to have to be more clear than that. Full sentences might help.”
It was the same demand that he made in any other situation. Her response came as naturally as breathing. “Master, may I please cum?”
Several more seconds passed silently but for the sound of Casper and her own guttural moans. “Are you planning to finish that question?”
“Sorry, Master,” Stacie stammered, buying time for her few active brain cells to figure out what she did wrong. “May I please… cum…” She was getting so close it was unreal. She was going to cum “from my ass?”
“That’s it. Now cum for me.”
Casper came first, pumping his semen into her rectum. Just a moment earlier, and her orgasm would have been almost unavoidable, and she would have been being disobedient. Because of his release now, however, she was glad of it, because it pushed her even further off the edge. Or orgasms overlapped until all that she could feel or think was pleasure, and when they ended, she was just a girl with a dildo in her pussy and a dog knotted in her ass. She felt wonderful.
“It’s not so bad now, is it?” her master asked, and she felt another wash of pleasure. He was pleased. But he obviously wasn’t looking for an answer, since he kept talking. “Get your plug before he can pull out. I don’t want to see a drop come out.”
“Yes… sir.” Casper had already turned around so that they were ass-to-ass, so in order to reach her plug, she actually had to drag him a little bit with his knot pulling at her sphincter. It was made more difficult considering that she was weak from climax and he was a big dog, but she did manage to reach it and place it below his cock before he was able to pull out. The instant that he did, she pushed the plug in, pushing his cum back inside and trapping it there.
“That’s a good girl. I’m so proud. Now you’ll keep that inside you until you wake up in the morning, understood?”
“Yes, Master.”
“You may take the dildo out,” he said, and she immediately complied. “When Casper’s done, take him out of your room, and then get some sleep. I’ll see you tomorrow.”
“I love you, Master,” Stacie murmured.
He smiled. “I love you, too.”
