Lisa began to cry out softly with passion, twisting her naked ass in the tub. "Ooooh, I bet you can make me come! I bet I'll come if you can piss long enough!"
She fingered open the lips of her pussy. Pulling at her cunt, she spread it open, and Johnny pissed against the pink slit. The tingling hot spray made Lisa's body tremble with strange sensations.
"Ooooh, baby, do you like to piss on mother?"
"I like it, Mom! I like to piss on your fucking cunt!"
"Mmmm, piss on my fucking cunt!" Lisa whimpered. "Piss on mother's fucking cunt! Ooooh, it's going to make me come!"
Lisa tried to lift her ass higher, but the tub was too small. She pulled at her pussylips, watching the piss between them. Her clit bulged with hardness.
Then, with a lewd giggle, Johnny jerked his cock upward.
"Oh!" Lisa gasped as he pissed into her face. She closed her eyes quickly, feeling him piss over her clamped lips. Her cunt lurched, and with a muted squeal, she thrust her cunt upward, her body shuddering as she started to come.
Johnny stared at his mother's cunt, watching the hairy lips pulsate as he pissed across her mouth and chin.
His piss-stream lost force.
Lisa looked up at her son with fiery eyes, then moved her tongue over her lips slowly, her orgasm calming. But she kept holding her knees to her chest, her ass writhing slowly.
"You pissed in my face."
"It made you come, didn't it, Mom?"
"Oh, and so good, too!" Lisa purred. "Johnny, I think I might like to be pissed on."
"You think? Mom, I know you do!"
"That's never happened to me before," Lisa said, fingering her cunt. "I wonder why I never thought about it before now."
Johnny's cock started to stiffen as he looked at her in the tub.
Lisa saw his cock getting hard, and with a lewd giggle, she gripped it in one hand, still holding one side of her cunt with the other hand.
Without saying anything, she began to piss, sending an arcing stream into the air, landing near the drain.
Johnny watched in hot fascination.
"I've never tried to piss on my back before." She giggled. "Can you see my cunt piss, baby?"
Johnny nodded, his cock throbbing in her hand.
"Put your hand in it," she urged.
Johnny leaned over, feeling his mother pissing into his palm. It sprayed over her lifted ass.
"Hot, huh?" Lisa gasped.
Johnny nodded, gazing at her hairy cunt until she finished pissing.
Lisa squeezed his cock hard. "See, you like it, too. It make your cock hard, baby." Johnny stripped his clothing off.
"What are you going to do?" she whimpered.
"Fuck you, Mom!" he panted, climbing into the tub with her. "I'm going to fuck your cunt! Fuck your piss-wet cunt!"
"Ooooh, go for it, Johnny!"
With the thrust of his cock into her cunt, Lisa began to squirm as she clutched his naked ass. She licked at his shoulders and neck, grinding as he fucked her. His weight crushed her drawn up knees to her tits, the rapid lunges of his cock pressing her into the bathtub.
"Ooooh, fuck mother's pissy cunt! Fuck me and fuck me! Fuck the piss out of mother's hot cunt! Ooooohhh, Johnny, make mother come! Make mother piss!"
"Hold your ass up, Mom! I'll fuck you until you piss!"
"Ahhh, do that! My cunt will piss on your hot balls! Fuck me and I'll come and piss on your hot, sweet balls!"
The excitement of having her son piss on her, especially on her face, created a fiery feeling inside her cunt as he plunged his cock in and out. She lifted high, pulling on his bunching ass, biting into his shoulder. Everything they had done together, the things they had seen, had sent her passions soaring, but letting him piss on her was the most exciting of all. It made her feel more excited than walking naked with him in the darkness, or fucking him in the post office or behind the hedge.
"Come in my cunt!" she wailed. "Spurt that hot juice up mother's cunt! Piss in mother's cunt… drown me with come juice and piss!"
"Uhhhh… uhhhh, Mom!"
"Baby!" she wailed, her orgasm exploding in fiery strength.
They spent the day trying to understand Lisa's increasingly wilder hungers. She was not bashful about them, only unable to understand why her desires were turning more and more toward the exotic, the unusual. Johnny had never heard of such things, but she was pleased with his eagerness not only to listen to her, but to agree to try some of them.
He watched her slide her dress to her thighs.
He pulled his cock out of his shorts and fondled it as he watched his mom spread her legs apart and rub at her cunt. He dropped to his knees between his mother's slender thighs, licking and kissing at the creamy, satiny flesh.
"Kiss mother on the cunt," Lisa purred, spreading her pussy with her fingers. "Kiss my cunt, baby."
Johnny kissed it, making an exaggerated smacking sound.
"Mmmmmm, lick it just a little."
He pushed his tongue out, licking up and down the slit, tasting the hot juices. He twirled his tongue over her clit, making Lisa's hips jerk.
"Is this making your cock hard, honey?" she gasped. "It's sure making my cunt wet and hot."
Johnny pulled away from her cunt and showed his cock to her.
Lisa mewled as she saw his cock jerk up and down with hardness. The head of his cock was very swollen, his pisshole seeping. She motioned for him to stand up and as he did, she closed her lips around his cock, sucking it slowly with little moans of pleasure.
"Mmmmm, so hard, so hot!" she moaned softly. "Johnny, fuck me! Fuck me in my cunt, then my ass, then my mouth!"
