Derek's perspective:

I love submissives. I love it when they crawl on the floor, humiliate themselves, and offer you complete power over their bodies for the sole purpose of enjoying themselves. I enjoy training them, showing them who is in charge, pushing them to their limits, and having them ask for more. Good submissives are rare. But before me stands a woman who has dreamed of kneeling at the feet of a master her entire life. It's a shame I have to give her back. Eva is a diamond in the rough.

My cock twitches in my pants as my wife suggests a game. Sylvia can be vicious, and that's what I love most about her. It's been two days since Eva has been allowed to orgasm. She's been craving it, and my wife intends to take advantage of that.

"Let's see, how far will you go to earn the right to come?"

Sylvia explains the rules of the game. They're very simple: she and I will propose challenges that Eva can choose to accept or decline. Each challenge gives her a chance to come. We will, of course, be the judges to determine whether the challenge has been sufficient to earn an orgasm.

Naked, kneeling on the floor in front of us, I can see in Eva's eyes that she's ready to take a lot to relieve herself. It turns me on like crazy. My wife knows it. She slips her hand into my pants and strokes me vigorously. I can feel that we're going to have a lot of fun.

To start with, Sylvia challenges our little slut to have her pussy whipped until she orgasms. Before agreeing, she can't know what instrument will be used to strike her, nor how many strokes she will receive.

"I accept," says Eva without hesitation.

No surprise there! She's so horny she's dripping all over the floor.

Sylvia and I find it amusing. My wife instructs Eva to get into position: on all fours, face down, legs spread wide.

"Beg me," she orders, to add to the humiliation.

"Whip my pussy, I beg you."

She squirms, her swollen lips perfectly visible in this position. I regret that we didn't give her a plug, but I trust Sylvia. In fact, I see the vixen picking up a leather strap. The submissive is going to suffer. Her pussy will be all shades of red.

The first blow falls on her sensitive flesh.

"That'll be 12 strokes for you, and don't forget to thank me."

"Thank you, mistress!”

Sylvia alternates between gentleness and severity. Eva will probably not be able to come, but she puts on quite a show. The little squeals of ecstasy between each stroke of the strap are music to my ears.

"Oh, too bad, you didn't have an orgasm. Well, I think you'll have to win the next challenge to relieve yourself, you poor little doggie."

It's my turn to come up with the next challenge, and I'm feeling particularly creative.

"I want you to write down all the sexual encounters you've had, in detail, and give them a rating. Don't forget anything—every blow job, every time you were fingered counts. You have all the time you need to do it, but be careful, every 15 minutes we'll add a little accessory to spice things up. Do you accept the challenge?"

"Yes, Master," she replies, her voice greedy.

We give Eva paper and a pen. She has to stay on all fours, which I imagine makes it quite uncomfortable. We start the timer and, for the first 15 minutes, Sylvia gives me a blowjob. She knows how much it turns me on to play with a little whore in training. After 15 minutes, I add a well-lubricated plug to the submissive's tight little hole.

"Mmmh!" she moans.

"Careful, bitch, you haven't earned the right to come yet."

After 30 minutes, Sylvia adds a clamp to her left nipple. Later, the right one gets the same treatment.

"You know where the next clamp is going."

Eva doesn't like having her nipples pinched. However, she can't finish the job before the next 15 minutes are up.

"Please, my clit is sensitive," she whines, spreading her thighs as if begging us to be gentle.

I have the honor of placing the clamp on her swollen button. I enjoy pulling on it a little just for the pleasure of hearing the submissive's cries. Then I activate the special feature of this clamp. It's a vibrating clamp. Oh, what a joy to see the look of defeat in Eva's eyes when she realizes what's happening.

"If I were you, I'd hurry up."

But she doesn't hurry. She loses her concentration. This earns her weights that are added to the clamps on each of her nipples. We have to gag her to stifle her moans. In the end, Sylvia joins in and gives her little racket strokes on the buttocks. After more than two hours, Eva finally finished her homework.

"Do you think she deserves to come, Derek?" my wife asks me, handing me the handwritten pages.

"Definitely not. It took her too long. But I'm feeling generous. If she kisses our feet, I'll let her remove a few accessories."

Eva's eyes widen.

"Oh, I forgot that part, didn't I? The accessories can only be removed if the challenge is successful. And you look so cute tied up like that, maybe you'd like to keep everything on for the next challenge."

Sylvia removes the gag from our submissive, and that's all it takes for her to throw herself at our feet, kissing them greedily. I'd love for Bryan to be here to see the downfall of his little Eva.

"Okay," I say, pushing her away with my foot when I've had enough. We can take everything off her, but she keeps the clamps on her nipples.

"Now, let's see." Sylvia pretends to think once she has stripped Eva of almost all her accessories. "Oh, I know, would you like to try cumming with a ginger root up your ass?"

Oh, shit! Just thinking about it makes my dick itch. What a great idea! And judging by Eva's face, she's never heard of figging. Of course, she accepts the challenge.

Sylvia goes to the kitchen and comes back with a nice piece of fresh, peeled ginger root. The slut gets into position to receive it, not knowing what to expect. She's so turned on that I wouldn't be surprised if she managed to orgasm.

"Here you go, doggy, I hope you like it," says Sylvia as she pushes the root into Eva's tight hole.

It takes a few minutes before the heat is felt. Eva fidgets while Sylvia moves back and forth with the improvised plug.

"Ouch!" Eva moans.

"It burns, doesn't it?" Sylvia asks her, almost sympathetically.

"Yes, mistress."

"Poor little doggie, maybe you'd like me to jerk you off to help you cum."

Eva hesitates, feeling that she's being tricked again.

"I'm afraid I'll have to leave the ginger in your ass until you come. After all, you accepted the challenge and failed the last two times. What a disappointing whore you are. So now you're going to come for your master. But since I'm nice, I can polish your little button."

Eva struggles with the heat. Out of breath, she finally accepts Sylvia's proposal. And then, my wife uses her hand covered in ginger juice to torture the poor submissive's clit.

"Ohhh," shouts Eva.

Sylvia jerks her off vigorously and despite the pain, Eva explodes in a blazing orgasm. Sylvia drops her to the floor.

"One orgasm out of three challenges. That's very disappointing, as I'm sure you can imagine,” I say, leaning over the submissive. "That deserves a punishment. But first, you're going to do us the favor of relieving your masters."

Despite her post-orgasm exhaustion, Eva licks Sylvia's pussy and then sucks my cock like a vacuum cleaner. Rather than letting her swallow my cum, I ejaculate on her face. I then ask Sylvia to fetch me a marker, which she quickly brings me.

"There you go. Since you're not worth much, people will easily know what you're good for," I say as I write the words cum dumpster on her forehead.

"Now come here," I add, tying a leash to her collar.

I drag her to the front door and turn to see her reaction. Damn, she's excited! She knows I'm going to expose her like this, and it makes her wet. I pull on her leash to take her outside. I tie her up in the middle of the lawn, in full view of the whole neighborhood. Luckily, people know us well because the scene is shocking. A submissive woman, naked except for a leash and nipple clamps, covered in cum, marked with a Sharpie, humiliated for everyone's enjoyment.

"Since you like to behave like a dog in heat, it's about time everyone knew that's what you are. If a neighbor walks by, you act like a dog. Wiggle your butt, stick out your tongue, and pant loudly. If someone talks to you, you can't answer. Only bark. Obviously, dogs take everything they're given, understand?"

Docile, Eva barks. It makes me laugh.

"Come on, be a good dog!"

Following my instructions, she stands on her tiptoes, her butt on her heels, her arms held out in front of her, and wiggles her hips. With her tongue out, she pants with desire. She is utterly ridiculous.

"Good," I say before leaving her there.

Sylvia and I stand at the window to watch our submissive. We're going to have a lot of fun. Especially since Sylvia tells me she called a few neighbors to make sure they come for a walk by the house.
