Timmy pressed his ass tighter into her face, twisting as she rolled and licked.
"Suck my ass, you fucking cunt!"
Donna sobbed, unsure if she felt ecstasy or shame. She closed her lips against her son's asshole, sucking very hard. Her mind was reeling, but not so much she couldn't taste her son's asshole. It almost seemed that the heat of his asshole blistered her tongue, searing her lips. She sucked hard and pounded on his asshole with the tip of her tongue, while jerking his cock wildly. She ran her tongue up and down his asshole, licking and moaning with rumbling ecstasy. She placed the tip of her tongue at the tightness, and pushed as hard, as she could.
"Ohhhh, that's it, Mom!" Timmy yelped.
Donna's tongue penetrated his asshole, going in about an inch. The tightness closing about her tongue sent wild tremors up and down her flesh. She fucked her tongue in and out, her lips constantly sucking. Her fingers dug harshly into his hip, her right hand still jacking back and forth on his cock.
"Tongue my asshole!" Timmy urged, his young body shaking. "Tongue me up my asshole, Mom! Eat my ass, suck my asshole!"
"Mmmm!" Donna wailed into his ass, his ass cheeks closing against her face.
Her tongue seemed to go deeper and deeper. She thrust her tongue in and out, still sucking as hard as she could. Timmy's cock was intensely hard in her fist, and she realized her son would be coming very soon.
Without warning her, Timmy suddenly jerked upright, turning to face her swiftly. His cock swung to her face just as the first hot gush of come juice erupted from his piss hole. He fucked his cock into her mouth quickly. Donna wailed with delight, her cunt contracted with orgasm along with his prick. The hot come juice burned into her throat as she cupped the checks of his ass again. She sucked frantically, swallowing hungrily, her eyes blazing with rapture.
Timmy held the back of his mother's head, his cock pressed deep into her wet, hot mouth, his legs trembling.
"Ahhhh, that was real good, Mom," he moaned softly, his chest heaving up and down. "You're getting real good!"
"It's all for you, Timmy," she murmured when he lifted his cock free. She leaned back on her hands. She was wet with piss, from her forehead all the way to her tits. Timmy's piss glistened on her shapely tits. The top of her dress was soaked.
Timmy spread his legs over her shoulders, rubbing his cock and balls into her face. Donna purred as she moved her tongue from her mouth, licking at his balls, slipping her tongue into the crack of his ass. She licked every place at her son's crotch as he rubbed back and forth.
Then he pulled away. He sat on the couch, grinning at her.
"You look like shit, Mom," he said.
"It's your fault," she said.
"Maybe, but you sure enjoy it."
Donna grinned at her son, a wicked yet shy grin. Still leaning back on her hands, sitting on her knees, she looked at him with slightly unfocused eyes. Her skirt was halfway up her thighs, her tits completely exposed. From her waist up, she was drenched in his piss. There was a warm glow inside her, a feeling of deliciousness. He remained standing above her, his shorts at his knees. A glistening drop of come juice beaded on his piss hole. With a soft purring sound, she leaned forward and swiped the tip of her tongue over it.
"Mmmmmmmmmm, so sweet, Timmy," she whispered, looking up at him and pressing her chin into his cock and balls. "I love it when you come in my mouth."
"I thought you didn't like to suck cock, Mom," he replied. "I thought that was what you said."
"I hated it before," Donna answered. "But I love to suck your cock. I don't know, Timmy. You just taste so good to me! So hard, throbbing, and when you come, it makes me shiver, and I come, too. My cunt really goes off when you do."
"Fucking cocksucker," he mumbled.
"Your cocksucker," she giggled, poking a finger into the crack of his ass playfully. "Your anything!"
Timmy sat back on the couch, his shorts at his knees. "Mom, why don't you piss?"
Donna gazed at her son, feeling a flush come over her face.
"I wanna see!" Timmy said. "I wanna watch you piss."
"Honey, that would…"
"In your panties," he interrupted.
"In my panties?"
Timmy nodded.
Her face burned with shame. "Timmy, please. That's sort of personal for a woman, and in my panties? That's crazy."
"Who cares, fuckface?" he replied. "I wanna see you piss in your fucking panties, Mom."
Donna trembled, feeling her son was deliberately trying to shame her, humiliate her. She wanted to comply with his request, but it would be horrible, letting him watch her piss, and in her panties.
"Get on the table," he said.
Donna saw his cock was stirring, starting to lift. She ran her tongue across her lips, the taste of his come juice and piss lingering in her mouth. She stood up and moved to the other side of the table, putting one foot on it. Facing her son, she hesitated; Timmy watched, seeing the inside of her thigh, the crotch of her panties.
Donna tested the table by pushing down on it with her foot. The glass was heavy and would easily hold her weight. She stepped onto it, still facing her son. There was a pink flame on her pretty face, but she felt she had to piss. She stood with her feet apart, drawing her dress up her long thighs. She kept her eyes on his cock, shyly glancing at his face. His cock was becoming harder.
Holding her dress bunched at her waist, she felt her legs shaking.
"Squat down, Mom," Timmy grunted, his eyes burning hotter as he stared at her crotch. "Just squat on the table and piss."
Donna squatted, going along with what her son wanted despite – or because off – her deep sense of humiliation. The crotch of her panties stretched over her cunt, and curling hair stuck from the edges. Timmy's eyes lingered there, his cock lifting into hardness again. She saw him move his tongue across his lips.
"Piss, Mom!" His voice broke into her thoughts. "Come on, start pissing in your fucking panties!"
Timmy now gripped his cock tightly.
Donna blushed, her knees spread, her ass resting on the heels of her feet. She looked down, seeing her panties, her blatantly erotic exposure. She tried to piss, but it wouldn't come.
"Piss, damn it!"
A small dribble of piss moistened the crotch of her panties, and she moaned softly.
"You call that pissing? Come on, Mom! Piss a strong stream in your panties! I wanna see you really piss!"
Donna exerted pressure. She began to piss. The crotch of her panties became wet, piss seeping through them and falling onto the glass top of the coffee table. She closed her eyes with shyness. A long forceful stream began to flow from her cunt. She felt wetness on her thighs as pee sprayed from the crotch of her panties. She felt like crying with humiliation but on the other hand, she also felt an excitement of wanton delight.
"Stop!" her son commanded.
Startled by Timmy's voice, Donna stopped pissing, glancing at him from lowered lashes. Timmy crawled beneath the glass-topped coffee table, lying on his back, gazing up at her crotch. His cock stood up in hardness, his balls tight at the base. With her son looking at her this way, right up her crotch, Donna felt very ashamed of herself and that very shame created an erotic sensation within her that was stronger than ever.
Timmy looked at his mother's crotch, seeing the tight way her panties held her creamy ass, the crotch of them soaked with her piss. He gripped his cock hard, licking at his lips with excitement.
Donna began to piss again.
Once more, pee sprayed from the edges of her already-soaked panties. The piss was warm as it sprayed along her inner thighs. She began to tremble with perverse excitement.
Now that her panties were thoroughly drenched with hot piss, Timmy said, his voice husky, his fingers moving slowly up and down his cock, "Pull your fucking panties to one side, Mom! Show me your pretty cunt! I wanna see piss spurting out of your fucking hairy cunt!"
