Cassie has to crawl on all fours and through the hall. This means that everyone else, including her dress, is gone.

Cassie stops, horrified.

"Come on, get down on all fours! Then you can go on." Coach.brown shouts loudly.

"But why?" Cassie asks.

"Because I said so! Get down now! Either volunteer or I'll get the boys back and tell them to make you." He declares loudly. Cassie shakily gets down on her knees and finally on all fours.

Slowly, she continues to crawl through the hall.

"I can think of something to say!" Says the coach.

"Wait a minute, stay like that!" He orders. Cassie is already afraid that he's going to come behind her and just fuck her from behind.

But that's not the case. He walks past her and leaves the hall.

He stays away for a while and Cassie remains rooted to the spot on all fours, afraid that she would get into trouble if she stood up again or just sat down.

A little more time passes and Cassie hears the door to the gym open.

She hears the heavy footsteps of Coach.Braun coming towards her and then feels him put something around her neck. It smells disgusting. Cassie raises her hand to feel what's on her neck, but Coach explains,

"It's the collar of Donut, our janitor's old dog." He then pulls the collar tighter so that it fits like a second skin.

"Don't worry, I'll buy Donut a new collar later. Then you can keep this one for yourself." Then it clicks and Coach.Braun stands up.

"I got the lock from Mr. Anderson, so you can take it off whenever you want because you know the code, he says. He didn't tell me the code. And now let's go, you've got two more laps to go!" Says Coach.brown excitedly.

But Cassie grabs her collar first.

She realizes with a shock that there is a lock blocking the way where she could release the collar. She tries to calm down.

("It's all right, you saw the code on the piece of paper earlier, you'll remember it!") she thinks to herself and it really does calm her down.

"Let's go now!" Shouts Coach.brown.

Cassie starts moving and crawls on. After one lap, her knees hurt, but she just keeps going.

"If I'd known you'd like it so much! I've got another of my ex's cocks at home, I'll bring it to you tomorrow so you can wag your tail like a real dog!" Shouts Coach.brown. These words leave their mark on Cassie. She gets tears in her eyes. Out of shame, out of despair, out of anger, but also out of frustration that she has let it get this far. When she finally manages to get the third round over with, Cassie stands up.

"What are you up to?" Coach.brown asks.

"That was three rounds, I'm done!" Says Cassie almost confidently.

"You didn't thank me when I helped you up after the push-ups! So one more round!" Says Coach.brown and laughs evilly.

"Please coach! My knees hurt!" Says Cassie, but is already getting back down on all fours.

"Good, you don't have to do a full lap. But then come crawling to me and ask me for forgiveness." Says the coach.

Cassie isn't sure if she wouldn't have preferred to crawl this one round, but she gets to her couch now.

When she arrives in front of him, she stays on all fours and begs.

"Please, forget about me, Coach!"

"Oh, you can do better than that! Much better!" Says Coach.Brown.

Cassie knows what he wants.... he wants what all men want.... She goes to the waistband of his sweatpants with her hands and wants to open them, but Coach stops her.

"There you go! You're a bitch! Use your mouth!" Said contentedly.

Cassie comes to his cords with her mouth and just as she is about to pull them, the door to the hall opens.

"Coach, we're waiting for Cassie!" Says a student and Cassie sees her worst expectations confirmed.

"What, get out! Everyone out of the gym! If I find another one of you in the building, you'll all be in big trouble and the season will be over!"

Shouts the coach indignantly.

The door slams shut and Cassie hears a lot of noise as apparently all the students are now leaving the gym.

He looks back down at Cassie.

"I must have robbed you and the boys of a little adventure." He says, grinning.

"It's no big deal." Cassie says, trying not to let her relief show.

"You had plans." Says Coach.Brown and rudely stuffs the waistbands of his pants into Cassie's mouth.

Cassie picks up where she left off.

She pulls on the tapes and the pants slide to the floor.

She also pulls the underpants down with her mouth. The taste is more than strange.

An already stiff penis jumps out at her. More or less voluntarily, she takes her coach's cock in her mouth and sucks it.

"Oh yes! You're doing well!" He moans. Cassie is pleased that for a change someone is not beating her up because she can't suck and continues to suck happily and excitedly until she realizes what she is doing here and that this is no reason to be excited.

Cassie is confused by herself.

"You're so good! You're doing brilliantly!" He praises her.

A feeling of security and reassurance spreads through Cassie.

Is it because he has just sent the others away, is it because he is talking to her so nicely now, or is it because she has come to terms with what is happening here? Cassie doesn't care at this moment.

She knows there's nothing she can do about it and she doesn't feel the need to at the moment.

"You like that, don't you?" The coach asks. Cassie nods her head.

"You're such a sweet and good girl. Do you want to keep being so nice to me?" The coach asks kindly and strokes Cassie's hair. That feels nice. Cassie nods. She wants to keep being nice if he keeps being nice.

"You can enjoy this, no one will bother you." He says in a reassuring tone.

The way he speaks really does have an effect on Cassie. She feels safe and secure.

"Would you like to do this every day?" The coach asks.

Cassie nods again, because she wants to feel this safe and secure every day.

"Come with me." He says gently to her and helps her up.

"Thanks." She says, looking her coach in the eye.

Together they go into his office, not far from the changing rooms. He reaches into the drawer, pulls out an application and hands it to Cassie.

"Here, you should go to the gymnastics club. Otherwise someone will get suspicious as to why you're with me every day." He explains to Cassie and strokes her.

"It'll be a new club that's just you. And it's completely up to you whether you fill it out now." He says again in that way that makes Cassie feel so good. Cassie is out of her mind. Of course she wants to go to this club to have this feeling of security every day.

She picks up the pen.

"Check there, daily, extra lessons, relevant for promotion, extracurricular activities, absolute obedience ....." and much more says the coach and has Cassie draw up a club contract that she would never sign with a clear mind. From the outside, it reads like a normal contract for an Club, even though it says [teacher] in the column for the training device. She herself even insisted that she write in compulsory attendance so that they would actually meet every day.

What she didn't realize is that Coach.Braun didn't write a dash or any other name in the column for possible substitute teachers, but wrote all. Wrote.

"Only sign it if you really want it! The contract is then binding!" The coach explains again.

But Cassie takes the pen and signs.

"You're a good one! Now you can finish up and then go." Says the coach with satisfaction.

Cassie is overjoyed and sucks the Cock of her otherwise so mean, but now so loving teacher.

"I'll bring you the tail tomorrow. Would you like that?" He asks again nicely. Cassie doesn't know what kind of tail he means, but she nods. At that moment it happens and he cums in her mouth with a gush and a loud moan.

Cassie would like to stay with him a little longer, but he says.

"And now go and change! I've got to sign up for an club!" Then he pushes her to the door of his office and closes the door.

Satisfied, Cassie goes into the changing room.

She goes to a mirror and looks at herself. When she sees herself, the smile disappears from her face.

She has a necklace that says big donut on it. She wants to remove it.

And looks at the combination lock.

What was the combination? She can't think of it...

She tries a few times, but then gives up in frustration and looks for her dress.

She searches and searches, but it's not there. Panic rises in her.

What's wrong with her? What should she do? She has a collar on that she can't get off, her dress is gone ... again. And what kind of contract has she just signed?
