At the exact same instant, Stepmother grabbed a thick bunch of the coarse black hairs growing around Mom's asshole. She twisted those hairs together into one stiff little rope. Then she used that rope of Mom's own anal hair like a rough brush and scraped it back and forth directly over Mom's hole. Right after that, with her other hand, she suddenly yanked the tweezers still clamped on Mom's clit straight downward as hard as she could.
Mom's whole body suddenly went stiff as a board. Her fat ass cheeks clenched so hard the skin turned pale white, every muscle in her thighs and belly trembling. Her toes curled until the joints cracked. Then, WHOOSH, an absolute flood of hot, clear squirt exploded from her pussy and urethra at the exact same time. It shot out in long, powerful, messy arcs, splashing loudly against the sofa, the floor, and mom's glass, drenching everything in seconds.
Stepmother was ready with a huge crystal water glass. The moment Mom started squirting, she slammed the glass tight against Mom's twitching pussy lips, sealing it right over her hole. Every hard spurt shot straight into the glass: first clear, watery streams that looked almost like piss, then thicker, creamy white juice straight from deep inside Mom's pussy. She held it there until the glass was almost full and warm steam rose off the surface.
Mom was still completely gone, floating in that thick, brain-melted orgasm fog where nothing exists except warm, buzzing emptiness. Her eyes stared at nothing, half-lidded and glassy, a thin string of drool hanging from the corner of her mouth, her whole body giving little useless twitches like a broken toy. That was the exact moment Vivi decided to strike.
She knelt behind Mom's spread legs, dug her nails into those fat, trembling ass cheeks, and yanked them apart so wide the skin in the crack went shiny and pale. The swollen, red anus winked helplessly in the center. Vivi took the cold metal tweezers, opened the sharp tips, and without the tiniest bit of mercy started stabbing them straight into the soft pink ring just inside Mom's asshole. Jab-jab-jab-jab-jab, fast and cruel, each poke hitting a different spot of tender flesh. Mom's walls fluttered and spasmed like crazy, shrinking tighter and tighter until the hole closed down to a tiny hole no thicker than a drinking straw.
Mom hadn't even started to come back to senses yet. Before she could feel the first twitch of awareness, Vivi snatched the bowl of leftover chili oil from lunch, still bright, angry red and swimming with pepper flakes that floated like evil little fish. She plunged her entire index finger up to the knuckle; the oil was so thick it coated her skin in a shiny, dripping glove. Then, in one brutal motion, she lined that finger up with Mom's clenched hole and rammed it into the hole.
Mom's body jerked, but she was still too dazed to scream. Vivi twisted her finger deep, scraping the burning oil over every fold and wall inside Mom's anus, painting the sensitive lining bright red. She pulled out slowly, watching the hole try to close, then smeared the rest of the oil all around the outside ring, over the swollen hole, down the tender strip of skin between asshole and pussy, until everything glistened wet and scarlet.
Less than three minutes from the first orgasm to the final smear. Three minutes, and Mom's entire world became burning pain.
The first real scream ripped out of her throat like an animal being slaughtered. "AAAAAHHHH!!! MY ASSHOLE!!! IT'S ON FIRE!!! IT BURNS!!! IT BURNS!!! MAKE IT STOP!!! PLEASE!!!" Mom thrashed off the sofa, crashed to the hard floor, rolled onto her side, then onto her back, then onto her stomach again, both hands clawing desperately at her burning cheeks, legs kicking wildly, tears pouring down her crimson face.
Vivi stood over her, face cold and amused. She lifted one bare foot and drove her heel down hard, THUD, right into the center of Mom's inflamed anus. The kick lifted Mom's hips clear off the floor for a second before she slammed back down, face-first into the tiles, ass still pointed at the ceiling, sobbing and shaking uncontrollably.
"Shut up and feel your dirty hole, Linda," Vivi said calmly. "Tell me, is it nice and tight now?"
Mom could barely think through the pain, but she forced a trembling hand between her legs. Her fingers brushed the ring and she whimpered. It was clamped shut like it had been welded, hot and swollen and throbbing so hard she could feel her heartbeat inside it.
"G-Grandma… please… it hurts so much… it feels like acid inside me…" Mom sobbed, snot and tears mixing on her cheeks.
Vivi just rolled her eyes. "Shadow Slave, freezer. Biggest ice pop you can find. Ram it up the-bitch's asshole and don't stop until the whole thing melts inside her."
"Yes, Master!" Shadow Slave's eyes blazed with pure hate and joy. She dropped to all fours and scrambled to the kitchen so fast her knees squeaked on the tiles. She yanked open the freezer door, grabbed the fattest strawberry ice pop in the box easily three and a half centimeters thick, maybe four ripped the wrapper off with her teeth, and crawled back, the frozen bar already dripping pink in her hand.
Mom was still facedown, ass shaking, trying to clench the burn away. Shadow Slave launched herself like a predator. She threw her full weight across Mom's back, planted her bare ass right on Mom's spine, and crushed Mom's heavy tits flat against the cold floor. Mom's breath whooshed out in a pained gasp.
"Get, off, my body !" Mom tried to squirm, legs kicking, hands still clutching her burning cheeks.
