When he finally collapsed back onto his knees, his growls reduced to exhausted, tongue-lolling panting, Kristen freed one of her hands to wipe her sticky face clear. When her vision readied, she looked upon a nearly opaque pool of milky white slime covering her chest and dripping off her skin. Its source, a white, veiny, monolith, throbbed undiminished over its newly reclaimed quarry. The man it was attached to panted quietly, his enormous, sinewy body shining with a sheen of sweat.
He smiled handsomely through his labored breaths, “Holy shit. You are incredible, mom.”
Kristen smiled back, adoringly stroking his back and his ass.
“So are you sweetheart. You did such a good job…”
Then she curled her other hand around his pussy drill, testing its readiness.
“…for your first time back. Now remind me who I trained you to be.”
Garrett set to the grueling task of reclaiming his technique. Sex with his matron was a divine gift, but also an earned right; Kristen was a sexual martinet who maintained high standards for the boy, maximizing his potential and ensuring that he would never grow up to be a Doug. At the height of their incestuous affair, during Garrett’s summer breaks, she made use of the lad all day long, intermixing their frantic, passionate lovemaking with regimented drills and achievement tests. She had developed the course after a lifetime of sexual experience, and unlike piano, never had to motivate her students to practice their fundamentals. She too loved the practice, congratulating their successes with her shrill orgasms. Garrett, her most dedicated tutee, had practiced so vigorously and tirelessly that she had fallen in love with him.
As a master graduate of the course, the teen casually reviewed the curriculum of his adolescence without pause or prompt. He demonstrated every position and any variations, muttering the benefits and hindrances, and providing a practical demonstration until his tester shrieked her acceptance of his physical mastery. He often found himself filling a condom before he liked, but he leveraged the vigor of his youth, and before long, the balloon was in the trash and a fresh condom tip was pressed against his mother’s cervix.
Innumerable hours later, he once again heard the familiar rise in the pitch and volume of her’s howls.
“Garrett!! Ohhh you sweet fucking boyyy… you’re gonnaaa… make mommyyy…”
Taking advantage of the spooning position, he reached around and began fondling her swollen clit as he kept jabbing her deep sanctum hard and fast with his big, fat baton.
“EEEEEEEEEEEEEE!!”
The teen felt warm fluid gush around the condom, dripping onto his exposed balls. The violent maternal spasms along his tingling cylinder begged him to surrender. Since he had just finished making his teacher come in each and every position she had ever taught him, he decided to let go.
“Mommmmmm,” he groaned as his dong pulsed erratically, inflating the rubber tip with rhythmic swells.
Mother and son continued to hump until their desperate paroxysms cooled. Garrett pulled out with a sigh, the exit of his enormous piston evacuating a quantity of fluid from Kristen’s womb. He let her reach down and remove the condom as he kissed her neck and caressed her sweaty body. She tied it off and lazily tossed it on the ground, now that the wastebasket had spilled onto the floor
