Billy fucked his cock back and forth, faster and faster. The friction of his mother's squeezing asshole made his young body shake with passion. She clawed at his hairless balls as he fucked his prick back and forth, smashing them against her cunt. The wetness of his mother's pussy on his balls felt fantastic, as if her pussy juices were scalding them. He dug his hands into her wiggling hips, jerking her ass back as he plunged forward, driving his cock into the steaming depths of his mother's eager asshole, slapping against the asscheeks loudly.

　If her son had not been holding her hips so tightly, Donna would have been tossed to the floor. She looked up with glazed eyes at his crotch, clutching his balls in her hand. She could not quite see his cock up her asshole, and wished now they had gone to her bedroom so they could watch in the big mirror. But it was too late for that; she didn't want to lose her son's cock now. She didn't want him to take his prick out of her ass so they could rush to her bedroom. She wanted him to fuck her asshole raw, to squirt his young come juice into it, drown her with his thick, sweet come juice. She gasped with the force of his driving cock, felt the pounding of him against her naked ass. Her tits jerked and jiggled from the force.

　"Talk to me!" Donna sobbed. "Say dirty things to me! Ohhh, baby, please, talk dirty to me!"

　"Fucking ass!" Billy groaned. "Hot, tight, fucking asshole! Mother, I'm gonna fuck your hot ass ... I'm gonna fuck you so fucking hard in your fucking hot ass, you'll shit! I'm gonna make you shit, Mother! I'm gonna fuck my hard cock up your hot ass and make you shit all over your fucking self!"

　"Yes!" Donna squealed. "Make me shit! Fuck my ass and make me shit!"

　"Hot cunt!" Billy shouted. "Hot, wet, hairy cunt! Cocksucker ... hot ass ... wet cunt! I'm gonna come up your fucking ass, Mother! I'm gonna fuck your tight asshole sore!"

　"Do it! Do it, you motherfucker!" she yelled at him. "Fuck mother's asshole sore! Give it to me, you little cunt-licking prick! Give it to me hard!"

　Billy panted as he fucked furiously into his mother's asshole. The friction was driving him wild. Her asshole seemed to close about his cock so tight, sucking at his prick. His balls smacked her in the cunt, and Donna squealed with rapture.

　"Ram it deep and hold it there!" she shouted.

　Billy went deep, and then Donna stuffed his balls into her cunt.

　"Oh, Mother!"

　"I've got you now!" she sobbed. "I've got your hard cock up my asshole and I've got your precious balls in my cunt! Feel what I'm doing?"

　"Yeah!" Billy moaned.

　He felt his mother's asshole flexing on his cock, and the tightening rhythm of her cunt about his balls.

　With her son's balls caught in her cunt, his cock up her asshole, Donna shoved her finger into the crack of her son's ass. She rubbed at his asshole.

　"Don't move, Billy! Just hold your cock deep up my asshole!"

　Billy didn't move. He stood with his cock inside his mother's ass, his legs shaking. He felt his mother's finger rubbing at his asshole, and he gritted his teeth as she began to press. He groaned as her finger slipped into his asshole.

　"Now, I've really got you, darling!" she sobbed. "I've got your hard cock up my asshole and your sweet balls in my cunt. Now I've got my finger up your asshole! Don't move, and I bet I can make you come!"

　Billy didn't move.

　Almost standing on her head, Donna peered between her thighs. Her cunt and asshole squeezed and flexed, and she began to push and pull her finger, fucking her son up his ass. Billy groaned with the strange feelings that enveloped his whole crotch. His mother's finger seemed to go very deep into his ass, and, when he tried to relax the ring, he found he couldn't.

　"Let me!" Donna cried out in a hoarse voice. "Don't even try to relax your asshole! Mother will make you come this way!"

　She pumped her finger in and out of his asshole, and Billy was awed with the manner in which her asshole and cunt gapped at his cock and balls.

　"You'll sure enough make me come, Mother!" he cried in a thick voice. "You'll make me shoot it so hard up your ass! You want me to come off in your asshole, Mother?"

　"Yes!" she sobbed. "I want to feel you squirt it into my asshole!"

　The pulling at his cock and balls was too much for Billy. The whole day had been exciting, and he was surprised that he could still come. He didn't know how many times his mother had drained his balls already, but it was more than he had ever jacked off in one day.

　"I'm about to come!" he groaned.

　Donna finger-fucked her son faster and faster, penetrating his tight asshole, her cunt sucking at his balls, her asshole squeezing his cock.

　"Come!" she urged. "Shoot it on me! Fill my fucking asshole with your sweet come juice, baby! Come in mother's ass!"

　Billy groaned, feeling his balls twitching inside the steamy wetness of his mother's cunt. His cock throbbed, and then he gave a wail of intense ecstasy.

　"Ohhhh, squirt it, baby!" Donna screamed when she felt the rapid spurts of her son's come juice splashing into her asshole, searing the walls. "Come in my ass! Fill my hot asshole!"

　The spewing of his cock sent a wild, rippling spasm through her pussy, the contractions tugging at his buried balls. Donna rammed her finger deeply into her son's asshole, feeling his ass ring clench as he came. She was coming so hard, she would have fallen on her face if Billy had not been holding her hips, pulling her ass tightly against his gushing cock. Her legs shook as her cunt exploded with a series of orgasms, the likes of which she had only dreamed of having.

　The final spurt flew from Billy's cock, and he gasped tiredly, his own legs shaking from the ecstasy. Still, he managed to remain on his feet, his cock relaxing inside his mother's asshole. He felt his balls being gently squeezed from his mother's fiery cunt. Then her finger pulled out of his asshole.

　Somehow, Donna managed to let herself down to the floor without falling. She curled up, knees drawn to her tits, her face aglow with satisfaction. Billy slumped to the floor, breathing heavily, his shoulders drooping.

　"You're wonderful, darling," Donna whispered. "You're the best fuck I've ever had."

　Billy grinned, breathing too hard to reply.

　Chapter 5

　Sometime later, Donna was stretched out on her bed.

　Billy was with her, sitting at her side, his knees crossed. He was wearing only his jockey shorts again, at her request. She had not told him why, but he didn't care. Whatever his mother wanted him to do, he was more than willing. Donna was very pleased with her son. He had, in this one day, brought some of her best fantasies alive, gave her tremendous pleasure. She knew there was nothing she could say or do with him that he would refuse.

　It had been a long day, yet seemed to have passed in only a few hours. It was after midnight, and both were tired. Donna lay naked on her back and they could see themselves in the big mirror.

　"I never did suck your cock off, baby," she said softly, caressing her own tits gently. "I jacked you off in my face, and you fucked me between my titties, and came in my face again. I fucked you on the couch, sitting on your cock, and then you fucked me up my ass ... but I never did suck your cock, did I?"

　"Something always seemed to come up, Mother," he said.

　"Like your cock?" she asked teasingly.

　"Yeah, and when it gets hard, I'll put it anyplace."

　"I know," she giggled lewdly. "Preferably in me. Did you enjoy sucking my cunt?"

　"You taste nice, Mother."

　"Even though my cunt was wet with piss?"

　"I didn't mind," he said. "I'd suck your pussy again after you pissed."

　She purred softly, running a hand down her flat stomach and through the thick curls of her pussy. She rubbed at her clitoris tenderly. "I bet you could get one more hard-on tonight."

　"I'd like to try." He grinned.

　"Sit on my stomach," she invited.

　Billy tossed a leg over his mother's stomach, sitting there.

　Donna looked past her tits at his bulging shorts. "Rub back and forth," she whispered.

　Billy rubbed his ass along her stomach, pressing his balls against her flesh. He cupped her tits and fondled them. Donna glanced into the mirror to watch, excited again. She stroked her hands along his thighs and behind his ass. She pulled him upward. Billy rubbed his crotch along his mother's tits, and Donna lifted her head, pressing her face into his crotch. She loved the sensations of a hot cock and balls against her face, and with her son wearing his shorts, the feelings made her cunt throb wetly.

　She pulled him over her face, and buried her mouth into his crotch. She inhaled the arousing scent of his crotch, sucking at his balls through his shorts, running the flat surface of her tongue along the slowly swelling shaft of his cock. She cupped his ass tenderly, kissing and licking and sucking at his shorts.

　"Mmmmm, you smell so good!" she purred. "I love to smell a man's crotch. It makes my cunt tingle and throb and I get so fucking wet!"

　Billy squirmed his crotch into his mother's face, rubbing his balls back and forth on her open mouth. Donna's eyes glittered up at him. She licked, pulling the crotch of his shorts into her mouth to suck. She rubbed her face at his crotch, mewling with pleasure.

　"Billy, piss for me," she whispered.

　"Piss for you?" he asked.

　"In your shorts," she purred throatily. "Push your crotch in my face and piss in your shorts."

　"Well, fuck!" Billy said, laughing. "You really want me to piss in your face this way, Mother?"

　"Please, baby."

　Sitting in his mother's face, Billy grinned down at her. He rested there and felt her hot mouth open against his balls. He dribbled a little, making his shorts wet where the head of his cock was. Donna moaned, and then Billy pissed.

　With a muffled squeal, Donna rubbed her face into the crotch of her son's shorts as he pissed. Like her shorts earlier, his jockey shorts were quickly drenched with hot piss. Donna purred as she rubbed her face into her son's crotch, shivering as his piss smeared her face. The wetness of his shorts excited her, and the scent of piss excited her.
