Karl remained standing and Olivia re-positioned her assist blocks. She backed up and rubbed her bare pussy in small moves along his flaccid dick. Karl let her work his shaft along her cunt lips until he began to harden from the warmth and slickness. He dropped to upright kneeling. Olivia watched in the mirrors as she bent and shifted her cunt to this new spot. She had more freedom of movement here and rubbed up and down, around and around his prick while it continued to grow. As he stiffened further, Olivia gently bumped his groin to exhibit in and out skills. Karl reached out and held Olivia's hips in his hands adjusting the timing. He stopped her and held her tight against him. Karl slowly folded to his knees, taking her along. She kept her knees off the floor during the move and balanced on three points: hands, feet and groin.
Dress rehearsals completed, Karl was ready for a real run-through with Olivia. He pushed her back into down dog with her feet on the assist blocks. Using her mirrored reflection to guide her actions, Olivia reached back between her legs and lowered Karl's hard cock from upright to horizontal. She fixed her moist folds athwart Karl's tip and rolled her hips up and down.
Karl decided to assist. He held her hips and poked with back and forth thrusts until he was fully seated. After that, they set a graceful rhythm that dragged Karl's sensitive crown along Olivia's crenelated vaginal walls. Karl was fascinated with Olivia's uneven inner texture. It seemed to be pleasantly rippled and added much to the experience.
Halfheartedly, Karl unpegged himself and lowered his knees to the mat. Olivia dropped her hips, realigned and reamed onto his slick stiffness. More pleasurable thrusting followed with shorter strokes matching the reduced freedom of movement. Karl held her fast against his groin as he lowered his ass to heels. Olivia stayed locked on. Now she combined hip rolls, hip rocks, strokes and vaginal clamping in random actions that scraped Karl's shaft and knob over her G-spot and every other spot in her rippled spongy passage. Karl watched her boobs oscillate in tempo.
Karl placed his hands on her shoulders and pulled her upright. Olivia reached back and interlocked her hands behind Karl's neck, anchoring her back to his chest. He reached around and palmed her warm, pliable breasts, lifting them even higher than her arched back had done. He stopped trying to move his hips and prick, letting Olivia supply the motions. He gripped hard on the boob masses. His thumbs brushed her nipples and he watched her face in the mirrors.
Olivia's eyes were closed and a dreamy expression covered her face. The room had a wistful silence, except for their light breathing and squishing of their interlocked groins. Ned kneaded her boobs as he continually brushed her nipples. Her nubs became solid little cylinders and he couldn't resist an occasional pinch and roll. Olivia's breathing got increasingly amplified, moaning low on the outbreaths. Karl felt his own finish approaching as well.
Olivia turned her head; eyes closed, she found Karl's open mouth and panted into it, lashing her tongue around his. Olivia's back arched even farther and she cried out her pleasure, hearing Karl's growl as he decorated her palpitating passageway with semen. The pair hugged each other through the crest of heat and relaxed slowly in the embrace.
Karl recovered first to find Olivia's bowed body held by his prick and hands. He gently squeezed her boobs as a sign for her to return from her stupor. Her eyes fluttered and she unclasped his neck, placing her hands over his on her boobs. They gazed at each other in the mirror. Olivia stirred further and rising, helped Karl get up and led him to the shower, where they cleaned away the 'coaching' residue under the warm pulsing jets.
Olivia and Karl felt refreshed after toweling each other down. They retrieved their shorts, panties and shoes. Olivia gave Karl a final hug, rubbing her nipples side to side on his chest. She turned and her body wiggled and jiggled as she left the suite.
Karl collapsed into the upholstered arm chair. He hoped to be Olivia's coach again soon. He admired her attitude and fantastic hard work. He could also hope to be Olivia's evaluator when she was eligible to be promoted to Junior. That would give him a full day and night to rediscover her charms, enhanced even more by the intervening training.
Karl heard a knock; it was his 2 o'clock appointment. "You may enter" he called. His next coaching tune-up appointment, topless, toned and pensive, glided meekly through the door.
