Academy policy was for trimmed girls to wear lighter weight leotards without an additional layer of material in the gusset. Basically, they were cheap and saved the academy money. Dry, they just about saved their blushes. Damp or wet, hardly anything was left to the imagination.

"No lies, Cathy. That person made good use of your talents. Now it's time for someone else to coax the best out of you, physically and mentally. Not only are you going to lose several kilograms but you're going to raise your math skills to a high level. Are we on the same page, Cathy?" He squeezed her cheeks.

Cathy nodded. "Yes, Sir, I suppose so." She would pretend to be enthusiastic, knowing that in few days she would be gone.

"Excellent." After slipping his hands out from under the fabric, he gathered the material so that it was bunched in her ass crack. Laying his hands on her naked cheeks, he massaged them gently.

"We don't want to alter the nice shape of your buttocks, just make them firmer. They are very impressive."

Cathy liked her peach. It was the rest of her body that needed an upgrade. "Thank you, Sir."

He removed his hands and raised them to her face. "I like 'Sir' when we are with company, but when we are on our own, I'm your Master. Is that understood?"

She didn't like him gripping her head with his hands while he examined her face. "Yes, Master."

"You are very cute, Cathy, and you have enormous potential, so I'm going to make you my prodigy. In three months, you won't be able to recognize yourself. Your first task, today is to show me your oral skills." He squeezed my face. "Do you understand?"

"Um, yes, Master."

"Excellent. Cathy, I want you to bend at the waist and part your feet by about eighteen inches."

Cathy knew what was coming, so there was little point in complaining. Mr Keita had tipped him off, probably via George, that she was compliant. Once George Williams had provided him with a sighter of her naked body, he had picked up the baton. He was confident that Cathy would comply with his wishes and hadn't wasted any time in urging her on.

As soon as he released Cathy's head, she got into position. After removing his phone from his pocket and placing it on the sofa's arm, he sat back a little, then waited for her to perform. His sports shorts had a tie. She pulled the bow open, then tugged on the elasticated waist. Once freed, his erect cock was ready and waiting for her mouth to dock with its purple plum-like crown.

"Take your time, Cat. There's no hurry. Show it the respect it deserves."

Cathy guessed that she wouldn't get any physical training that morning. The math teacher would find time to dress her in the leopard suit, but his priority was to break her in so that she knew her place whenever she was in his company.

She sucked, licked and lip-fucked his knob with a high intensity, morphing from one to the other but trying to mainly use her lips and teeth to good effect. The further down the road she could get him, the less time was needed to use her throat.

"Excellent technique, Cathy. George's information was rock solid..."

George's information wasn't all that was rock solid. The math teacher's cock was as hard as a lump of mahogany; and he was becoming impatient to feel the tightness of her throat. When he placed his hands on Cathy's head, she released her grip of his shaft, steadied herself with her hands on his thighs and began to bob her head.

"Very impressive, Cathy..." Out of the corner of her eye, she was able to see him tap a message on his cell phone, then return his hand to her head.

When the door opened behind Cathy, her instinct was to lift her head. "Ugggggh," she complained, but the dick filling her mouth muffled the words and the hands kept her head down.

"Quiet, Cat. Concentrate on this end and the other will take care of itself."

Cathy had to refocus to make sure her breathing was in sync with her throat thrusts. She had only swallowed a couple of inches when hands settled on her raised ass. Whoever it was, slipped his fingers under the gathered leotard's material at the high point and then slid them down. After pulling it out from her valley, he eased the gusset off her bulging labia lips and held it to one side.

As expected, she felt the man's blunt knob pushing, pressing with insistent intent against the entrance to her quim. "Ugggh," she groaned softly when the substantial intruder bore into her dry channel, stretching her teenage vaginal walls the deeper it dove.

"As tight as a virgin at both ends, heh?" the math teacher said smugly, but there was no reply.

When the stranger's cock reached her limit, he slowly began to withdraw while still gripping her left hip and the narrow strip of material tasked with covering the entrances to her orifices. Cathy tried to up the pace, but her throat fucker wanted her to take her time, possibly to allow his mate to catch up.

"Steady Cathy, there's no hurry..."

The mystery man was on his third lunge when she felt his stout shaft begin to move more freely. Within a couple of more thrusts, her juices came to the rescue. Then, he was rocking and rolling, pounding his cock into her youthful quim with power and precision. Cathy could feel her vagina heating up and liquifying. Then, accompanying the hots, a thrilling sensation began to build in her belly.

"Uhhhhhh," she groaned softly as her orgasm sizzled and fizzed through her nervous system.
