"I need to check your progress... Lay calmly and breathe like you are swimming at a long distance." I start smearing her pussy juices from my hand to her cleavage. Amelia's melons look even huger from this position and it is time to fulfill my old fantasy.

"But coach," she protests weakly as I adjust my position and place my regrowing dick between the spheres.

"Shhh. Close your eyes, relax, and breathe. I want perfect calm breathing" I say smiling and running my hands over her huge breasts while my dick slowly slides deeper in her cleavage

I keep stroking her breasts, feeling her hard nipples and the slippery skin of her chest. Her wide shoulders slowly relax and her breathing becomes steadier. She sighs quietly and brings her arms above her head, taking a position she would have while swimming on her back. Then she closes her eyes, bringing her expression close to that of true relaxation.

Perfectly shaven armpits, collarbones like those of a goddess, and a face of an angel make her irresistible. I am the luckiest man alive. The size of her breasts allows me to bury the whole length of my cock in her cleavage, enjoying the firm softness of her skin. I push her beauties together, simultaneously rubbing my ass against Amelia's muscular abs.

Her breathing is calm just as I ordered and this obedience only adds to my satisfaction. She is mine... She is mine to a much higher degree than if I would merely **** her.

I fuck her tits slowly, prolonging the pleasure as much as possible. Her lips part, I expect a moan but no. My order stands. She does breathe like a disciplined athlete, keeping her eyes closed and her body relaxed. Her cheeks are pink and she is sweating heavily as if it is not a slow titfuck but an intense training session.

My right hand is working over her left breast, squeezing and massaging it, while my lelf one keeps enough pressure to keep her cleavage tight enough for my dick to be comfortably hugged by her heavy watermelon-like orbs.

"Fuck, what a sweet slut you are... keep breathing!" I break the role of a coach but only for a moment. "you are doing... mmmm.... gooooood."

Arousal is written on her relaxed face and yet she maintains steady breathing. Amelia's ribcage is like one of an automaton, her lungs filling and emptying with sweet almost melodic sounds. I played a vital role in sculpting this body and now I reap all the benefits, it seems so fair, so satisfying.

I accelerate my pace, slightly lifting myself above her body and doing stronger and stronger pushes using all of the muscles on my back. The tip of my dick continues its journey in her cleavage, completely hidden by the softness of her breasts.

Even with this quite rough fucking of her upper body, she maintains the same steady breathing and her body remains totally calm. My orgasm hits sooner than I'd like but I am not complaining. In the last moment, I arch my back making my dick pop out of the confines of the cleavage and unload sticky liquid on Amelia's face, shoulders and tits.

"You did well... " I said finally standing up and giving my student freedom of movement. "You can dress. Few more such lessons and you'll be a proper sl.. swimmer."

"Yes, coach." The girl is a mess - her hair is all over the place, cum on her upper body, pussy juices all over her thighs. She grabs her black swimsuit and hastily puts it on, giving me a small show comparable to seeing her undressing. Swimsuits are the best for such young females. Athleticism, beauty, and raw sexiness - swimsuits accentuate everything. Most of my cum is now under the black fabric but some droplets are still on her neck and chin. I feel so satisfied with my 'work'.

"You can hit the shower now. And..." I rub my chin

"And?" She asks with a little bit of fear.
