As soon as her son finished coming, his cock pulling from her, Laura lifted her mouth, her eyes glazed. Still coming, she knelt, ripping at her blouse, tearing it from her body until she was naked except far her skirt.
"Piss on me!" she screamed, climbing into the bathtub and spreading out on her back, her skirt around her waist, her legs spread very wide, her cunt arching up, her hands feverishly spreading the hairy lips, her clit bulging up and throbbing as she kept coming. "Piss on me! Please, piss all over me!"
Jason glanced at Sammy who was on his feet and dangling his cock over his mother's naked body.
"You're really gonna piss on my sister?" he asked.
"We better," Sammy said. "Mom loves it. Come on, let's piss on her!"
"Hurry!" Laura sobbed, spreading her cunt as far open as she could. "Piss on my cunt… piss on my fucking hot cunt and in my face and on my tits and all over me! Ohhhh, God, I'm coming so hard! I can't stop coming! Hurry and piss on me!"
Seeing Sammy pissing on his sister, Jason stood at his side, holding his cock. Laura's eyes were glazed with mindless passion, but her mouth was wide open. She was making grinding motions with her hips, feeling her son's hot piss sting the lips and clit of her cunt.
Then her brother let go.
Laura screamed as the hot piss of her brother stung her tits, her son pissing hard on her hairy cunt.
"All over me!" she shouted. "Piss all over me! In my face, in my cunt, in my asshole, my legs, my tits!"
Both boys sprayed her body, drenching her hiked-up skirt. Laura began to whip at her cunt with her fingers, her ass twisting frantically, her cunt rippling with the most intense orgasms of her life.
When her son and brother arched their cocks and sprayed her face, she opened her mouth as wide as she could, shifted her head so they were both pissing into her mouth together. Hot, golden piss overflowed her mouth and ran out, soaking her cheeks, her chin, her shoulders.
Then she began to swallow.
She couldn't swallow all of their hot piss, but she swallowed enough to increase the power of her orgasm.
When the stream of piss stopped, she kept clawing at her cunt, but at least the orgasms were starting to become weak and fade.
In a few moments, she slumped in the bottom of the bathtub, her whole body drenched in piss. She could still taste her brother's come-juice in her mouth with their piss.
"Sis, you're something," Jason said. "You're more fun than you used to be."
Laura grinned up her brother and son, and lifted her hands to their cocks and balls.
"You ain't seen nothing yet, either of you."
