Teaching Billie

Billie claimed the first slot for a fisting lecture after the holidays. Her tutor Iwia didn't warm her up or go slow. She pressed right inside, knuckles and all, stretching the eager brunette wide on the spot. Billie's breath broke into short, high sounds. Her thighs shook but her hips pushed down, greedy for more. Iwia rotated her wrist, knuckles dragging across slick walls, then curled her fingers into a tight fist. Billie's back arched off the couch, heels digging in. Each time Iwia drove deeper she answered with a hoarse cry and another rush of wetness down her thighs. Sweat beaded on her stomach. Her clit throbbed untouched, yet she felt the orgasm building fast and hard. Iwia thrust steady, relentless. Billie's cries pitched higher. When she came, it hit so violently her whole body clenched around the fist inside her, pulsing hard enough to pull Iwia's wrist an inch further. She didn't let go until her muscles stopped fluttering. Then she stayed open, flushed and dripping, already asking for the next round.
