They make it to the shower.

He pushed her head up against the shower wall and then pushed the remainder of her against it.

He let out a low growl and bit her ear, causing her to gasp. Between the hot, steamy shower currently running and his cock pressed against her ass, she knew he wanted a release of his own; his cock thickened as he pressed it against her. "Didn't think your coach would notice you sneaking in some extra practice time when the gym was supposedly closed, huh?"

"Mr. Stone, please...I didn't mean to, please..." She whimpered back. If there were anything she had down fairly well already when it came to sex -- she was pretty good at roleplaying.

"Your training comes from my discretion. What you did was a very bad thing. Are you a bad girl?"

"No, I swear, I'm a good girl!"

He was so thankful the showers were empty when they came in.

"You're a good girl, huh?"

"Yes, Mr. Stone!"

He pressed himself up harder and used one hand to grab her throat. "Do good girls do bad things?"

"N-no sir."

He moved his hand up a little and **** his index finger in her mouth. "Good girls only do bad things if they want to be punished. Did you want this to happen?"

She whimpered.

"Answer me, slut." He pulled away and gave her ass a firm spank.

"Ah!" She squeaked out. "Y-yes, Mr. Stone!"

"What did you expect to happen?"

She hesitated and this time he pulled her off of the wall and slammed her against the wall with the faucet on it, her facing him. He nibbled on her neck. "What did you expect to happen?"

"I wanted Mr. Stone t-to punish his favorite student to put h-her in her place!"

He grabbed her neck now again and squeezed a little more. Not enough to hurt -- but enough to assert his dominance. "Who said you were my favorite student?"

"I-I did!"

"Are you going to prove that statement? Hm?" He squeezed just a little harder and she let out a little moan.

"I-I want Mr. Stone to let me prove that I should be his favorite student."

"And how are you going to do that?"

"I-I-"

He slapped the wall beside her and she squealed. "Stop fucking stuttering, you stupid bitch." He grabbed her by the shoulders and licked his lips. "How are you going to do that?"

She was shaking. "I'm going to suck on Mr. Stone's cock."

He grinned. "Hmph." He moved his hands to her shoulders and **** her down to her knees. "Get on the fucking ground then." He picked up her hair so it wouldn't fall in her eyes, and she looked at his throbbing cock and gulped.

Once again -- huge confidence boost.

She took it in one hand and slowly began to jerk it. He gave her a (gentle) slap on the cheek. "Did you say you were going to jerk me off, or suck me off? Make up your fucking mind or I will for you."

She hesitated for a long time. Longer than either would like to admit -- he began to get soft. He realized something had to be up.

She whimpered and legitimately trembled this time. "I-I'm s-sorry." She broke the roleplay. "I-I've...oh, man, this is really happening?"

He moved her hand off of him and knelt down beside her. "Hey, hey. Are you okay?"

"I'm so sorry." She looked at him and he swore he saw tears welling in her eyes. "I-I'm so sorry."

"Don't be sorry." He cracked an encouraging smile. "I'm not here to **** you to do anything."

"B-but what good is a sub who can't even...you know..."

He picked her chin up and grinned. "You aren't my sub, yet. I'm just your coach. Look, you did a good job with the roleplay. I'm really proud of that."

"Really?"

He laughed a little and she cheered up. "Yeah. I mean...that was some seriously good stuff."

"C-can we...can we try this somewhere else? I mean..." she sighed. "I'm so sorry."

"I know. It'll come naturally for you."

"I just...I mean, this is the second time now I've blue-balled you."

His eyes changed light. She noticed.

"Who said we were finished here?"
