Doctor Nancy opened the office door.
Joan jumped.
She had still been sitting with her skirt around her waist, legs wide open. She clamped her legs together and jerked her skirt down guiltily.
But Doctor Nancy had seen, and she grinned at Joan. Billy slipped from behind Doctor Nancy and glanced at the pretty girl behind the desk. He had not seen his mother's exposure.
Joan, with her face burning with embarrassment, noticed a wink pass between Doctor Nancy and the pretty receptionist. There was something strange going on here.
Getting to her feet, she smoothed her pink skirt over her hips and thighs. The girl behind the desk had flashed her cunt quickly at Joan.
"Everything is fine with Billy," Doctor Nancy said as she walked to Joan. "He's an excellent specimen. Healthy as a horse."
"That's good to hear," Joan replied, struggling to keep her voice normal.
"Still, I'd like to see him every week for a while," Doctor Nancy said.
"But if he's okay…"
"I'm still checking certain reflexes," Doctor Nancy said, close to Joan. "I'm sure you understand." She placed her hand on Joan's ass, slowly stroking it. "Besides, it's a real pleasure to find a boy so healthy."
Doctor Nancy's hand slipped off Joan's arm, resting on her hip. Joan felt a warm heat on her face when the doctor stroked her hips, and then, with a soft laugh, patted Joan's ass. It was part pat and part caress.
"There isn't any reason you have to come along every time," Doctor Nancy said softly. Then she looked at her receptionist. "That is, if you don't want to."
"I don't mind," Joan said. She glanced under the table where the pretty girl sat, seeing the hair of her pussy. Billy, near the exit door was looking at the girl, too, his eyes huge and hot. "Your… she's nice, and we always have a good… Visit."
"Wonderful," Doctor Nancy said. "Gail is so good with mothers who have to wait so long."
Her hand was still on Joan's ass, and it moved again, feeling softly, gently. Joan glanced at her son to see if he was noticing. His eyes remained on the girl at the desk.
"When should I bring Billy back?" Joan asked, aware of the huskiness of her own voice.
"Anytime," Doctor Nancy said. "You don't need to make any appointments."
Joan gasped.
Doctor Nancy had squeezed the cheek of her ass.
In the car on the way home, Joan thought about what was happening. Not only did Gail, the pretty receptionist, seem to be after her ass, but she was quite sure Doctor Nancy wanted it, too. She wasn't sure how she felt about this, except she knew there was an anxious burning between her thighs.
Billy, squirming in the seat, seemed excited. She looked at him, her eyes going to the front of his pants. "What's wrong with you, darling? Why can't you sit still?"
"Mom, I gotta tell you," he said. "About Doctor Nancy."
A tremor shot through Joan. "What about her?"
"She sucked me off," Billy said bluntly. "She sucked my cock off, Mom."
"When?"
"The last time we were there, and today she had me fuck her, but in her ass."
"Doctor Nancy had you fuck her in her ass?" Billy nodded, grinning. "She wanted me to peek at you and tell her what you did. You know, if you played with your pussy and all that."
"I wonder why?" Joan said, frowning as she drove. Remembering the caressing hand of the doctor on her ass, the playful squeeze, she thought she knew what was happening, but wasn't sure.
"Is it okay if I fuck her, Mom?"
Joan looked thoughtful for a moment, "If she wants you to fuck her ass, do it. I won't be jealous."
"I just had to tell you, Mom," Billy said, scooting across the seat and moving his hand beneath her pink skirt to feel her leg. "I don't wanna do anything you'd dislike."
Joan placed her hand on top of her son's, pulling it up her thigh and fucking his fingers between her legs. "That won't make me mad, baby," she said. "If Doctor Nancy wants it up the ass, give it to her."
Billy tilted his face up, kissing his mother's neck. "You're the best mother in the world."
Joan laughed, pleased. "Maybe so, but at least, I'm also the fuckingest mother in the world!"
Laughing with her, Billy pressed his hand into his mother's crotch. Her cunt was hot and felt good, even through the crotch of her panties.
"You like feeling of that cunt, don't you, Billy?" she said in a soft voice.
"Oh, yes, Mom," he gurgled, rubbing her pussy.
Joan slipped a hand from the steering wheel to his lap. "I hope you have enough hard-on for me."
"I'll always have a hard-on for you, Mom," he replied, snuggling closer to her.
Joan managed to open her son's pants. She lifted his cock free, delighted to find it half hard. She pumped her fist up and down, bringing his cock to full hardness. The throbbing of his prick sent her cunt into rippling pleasure against his palm.
"Inside my panties, baby," she said huskily. "Feel me up inside my panties."
Billy worked his hand into his mother's panties, feeling the soft pussy hair, then the moist cunt lips. Joan's cunt lips were puffy and hot. He stroked her clit, trying to twist it. Joan whimpered softly, wiggling her ass on the seat. She drove very carefully, keeping her eyes on the road.
"Oh, Billy!" she crooned. "I can hardly wait to get home. I want your cock so badly!"
Billy had shoved his other hand underneath his mother's ass, making her sit on it. He wormed a finger past her panties and into her cunt, fucking it in and out as his other hand massaged her swollen clit.
Hardly realizing it, Joan pulled the car into an alley, braking near a pile of cardboard boxes. Turning the motor off, she twisted to face her son. Her pink skirt was high, his hands under it. She gazed with burning eyes at his cock, her fist puffing on his hard-on.
"It was up Doctor Nancy's ass," she whispered. "In her ass… fucking her."
She squeezed his cock, making a bead of liquid form on his piss hole. She sucked in a deep breath, and without another word, dipped her face downward. Her tongue swept about the smooth cock head, licking away the beading juices. She inhaled a slight, yet somehow clean sexual odor on his cock.
Trying to visualize her son's cock fucking in and out of Doctor Nancy's asshole, Joan closed her lips about her son's cock, sucking on it with light lips. The odor clung to him, making her senses reel as she gobbled his cock deep into her mouth.
Billy moaned and scooted his ass forward on the seat of the car, giving his mother room to suck his cock. Joan pressed her lips at the base, the smooth head of his cock pressing at the back of her throat. She made purring sounds as her tongue lapped at the hard, throbbing cock shaft. She wasn't sure she could actually taste the skit of Doctor Nancy's asshole or not, but her vivid imagination made her think she did.
Shifting on the seat of the car, Joan drew her knees beneath her body, arching her ass upward. Billy shoved a hand down his mother's back as she sucked up and down on his cock. He drew her pink skirt up and over her pantied ass. While his mother sucked his cock, he caressed the lacy seat, then slipped his hand under the elastic at the waist. The smooth heat of his mother's ass, excited him as much as her mouth was exciting his cock. He stroked her ass cheeks, slipping a finger along the hot ass crack.
Joan mewled and wiggled her uplifted ass.
"Mmmmmm, baby, baby," she murmured, nuzzling his cock. "Your prick tastes so fucking good! Was it really up Doctor Nancy's ass?"
"Yes, Mom."
"Ohhhh, wonderful? Stick your finger in my ass, Billy," she purred, licking about his cock.
"If she can take it up the ass, so can your mother. Go ahead, honey, ram your finger up my asshole."
Billy pressed the tip of his middle finger against his mother's tight asshole. Joan whimpered with the pressure, and swallowed his cock again, making hungry sounds. She relaxed the tightness of her asshole, and Billy's finger slipped in. She felt her asshole stretching about his finger, feeling it go deeper. The sensation of a finger in her ass sent ripples of perverse pleasure flowing through her. She gripped his cock with tight, hot, wet lips, sucking greedily and waving her uplifted ass. While Billy fingerfucked her asshole. The unusual sensation felt good to her, and the more Billy fucked his finger up her asshole, the more she sucked at his cock. The throbbing heat of his prick between her lips and the dripping juices sent delicious explosions through her hairy cunt. With the orgasms twitching, it caused her whole to squeeze at his finger.
Billy didn't have to be told his mother was coming, and coming time and again. He felt it on his finger, the faster she sucked up and down on his cock. Her mouth seemed hotter than ever before on his prick. She had gotten a hand underneath his ass, the other moving up and down his thigh as she sucked. Billy twisted and writhed beneath her face, grunting softly.
"Mom, you're gonna get a mouthful," he moaned, his balls drawing up tightly in his pants. "You're gonna get a mouthful of come juice!"
"Mmmmmm," she moaned, sucking frantically, her throat burning for the creamy sweetness of his young balls. Her tongue licked hungrily. She fucked her uplifted ass on his finger, her cunt convulsing in stronger waves of orgasm.
Billy arched upward, trying to fuck his cock down his mother's throat. Joan felt the increased throbbing of his cock with her lips, and made muffled squealing sounds. She knew he was about to come before he said anything. She drew her lips up, clutching his hard cock just behind the cock head with them. Her tongue flapped wickedly across his piss hole.
The creamy juice of his balls erupted, gushing into her mouth hotly. Again Joan squealed, feeling the thick come juicy splash at the back of her throat. She swallowed hungrily, sucking very hard, her lips slipping up on the round head of his cock until they just barely covered his fizz spewing piss hole. She sucked very, very hard as he came into her mouth, filling it. A final orgasm boiled through her, and her ass swung from side to side as Billy kept fucking his finger into her tightening asshole.
Joan clung to her son's cock until she was certain there would be no more of that sweet, creamy come juice. She licked her tongue across his piss hole, sucking up what jism might be left there. When she lifted her face, Billy withdrew his finger out of her asshole. Sitting back on her heels behind the steering wheel, she grinned wickedly at him, her long legs beautiful.
"That cock is going up my ass when we get home, Billy," she said eagerly. "If Doctor Nancy can fuck it with her ass, then I can, too."
Billy grinned, feeling good. Leaving his cock sticking out of his pants, he rested a hand on his mother's thigh as she drove the car. Joan had not bothered to pull her pink skirt down, not caring about her exposure.
The car had hardly stopped in the drive when Joan and Billy were out of it, running for the door. Her skirt had caught on her panties, and her long legs flashed in the bright sunlight. Billy's cock swung to and fro as he ran.
Inside the house, Joan began tearing at her pink skirt, in a rush to get it off. Billy watched, his cock starting to stand up once again. His ability to get hard so quickly after coming off was a constant source of amazed pleasure for his mother.
"Get out of your fucking clothes!" she hissed hotly, sliding her panties down in a rush. "You're going to fuck me in the ass, honey, just like you fucked Doctor Nancy's ass."
Billy was ripping his clothes off in a frenzy, staring with excitement at his mother, seeing her beautifully shaped tits, her long legs, the flash of her thick cunt hair as she peeled her lacy panties off. His cock lurched and stood up in proud hardness.
Standing upright, naked, her tits straining outward, Joan gazed at her son's hard-on, as if seeing it for the first time. The idea of getting her ass fucked sent a tremor of anticipation rippling through her. Quickly, she turned her back to him, dropping to her hands and knees. She waggled her shapely ass, looking over her shoulder.
"Now, Billy!" she urged. "Fuck mother up the ass now. Ooooo, I want your cock up my hot ass, honey. Come on, get down here and fuck your mother's ass!"
Behind her, Billy stood watching his mother shake her pretty ass for his enjoyment. He could see the hairs of her cunt between her long thighs, the winking invitation of her asshole. His mother's ass looked wonderful to him, squeezing and flexing. His cock lurched as he dropped to his knees behind her.
Joan mewled and pressed her head and shoulders to the carpet. She grabbed the cheeks of her creamy ass, pulling them as far apart as she could. Arching her ass up, she looked extremely lewd, offering her tight asshole to him eagerly.
"Shove it in!" Joan yelped, twisting her ass in a tight circle. "Shove your cock up mother's asshole! Ooooo, Billy, I want it in my hot ass!"
Billy pressed the head of his cock against his mother's tight asshole. The head of it seemed very hot. He rubbed the head of his cock about her asshole, feeling the smoothness in the crack of her ass. Joan whimpered with increasing yearning to feel his cock split her asshole open. Her fingers clawed at her ass cheeks, causing her asshole to almost pooch past them.
"Shove it in me!" she called hotly. "Don't play with it, darling! You can play with my asshole later… but right now I want you to shove it in me deep! Come on, Billy… rain your cock up mother's fucking asshole!"
Billy slammed forward recklessly. His mother wanted it fast and hard, and that was the way he gave it to her.
His cock fucked into her tight asshole.
Joan screamed.
If felt as if her son had sliced her asshole with a knife. A searing pain shot through her as his cock penetrated the tight heat of her asshole, a pain she had never experienced before. But it wasn't an unbearable pain. On the contrary, it was a pleasure-pain that thrilled her, sent her cunt into spasms of sensation. Billy held the head of his cock inside his mother's asshole, feeling the tightness, the boiling heat. It was Joan who moved.
She slowly pressed her ass back, taking her son's cock deeper into her asshole. Her asshole seemed stretched, and the more cock she pulled into it, the better the feeling became. She felt the urge to shit as his cock fucked deeper, but she knew it was his cock, that she didn't really have to shit.
"Ooooo, it's all the way up my ass, Billy!" she whined, feeling his balls smashing at her wet cunt. "It's a good thing you're not any bigger. I couldn't take another inch."
"You're tighter than Doctor Nancy," Billy hissed.
"I've never been fucked up the ass before, baby," she replied, twisting her ass with his cock buried deep. "You're the first. Your cock is the first to fuck my asshole, Billy."
On his knees, Billy looked down at his mother's ass. He could see the tight ass ring closing about the base of his cock. He gasped when his mother started to move forward, drawing the tight ring of her asshole on his prick. His balls writhed with pleasure as he watched. When she had only the cock head inside her asshole.
Joan paused, took a deep breath, and pushed her ass back. She gasped as his cock fucked deep again. Then, shivering with perverse ecstasy, Joan began to fuck her son with her asshole.
"Ooooo, that feels so good Billy!" she hissed, turning loose of her ass and clawing at the carpet. "So tight… so deep… so hard. Ohhhh, fuck me, darling! Help me… help mother fuck your cock… with my asshole! Fuck me, baby! Fuck my ass… fuck mother's asshole! Please, please, please fuck me in the ass!"
Billy's cock tingled and burned with the tight heat of his mother's asshole. He gripped her rounded hips, digging his fingers into her firm, smooth flesh. When he started ramming his cock back and forth, pounding his balls against her hairy, juicy cunt, fucking powerfully into the gripping asshole, Joan squealed and whimpered with hot ecstasy. Her naked nipples scraped at the carpet, and that felt good to her, too. Billy began to fuck his mother brutally, fucking his cock up her asshole swiftly. She was being scooted forward on the carpet, but her ecstasy was so great, she didn't know it.
Billy grunted loudly with his efforts, and his mother squealed and gurgled with pleasure. His balls slapped time and again at her juicy cunt, and Joan couldn't resist pushing a band between her thighs, grasping his balls, squeezing them, trying to cram his balls into her cunt. She might have managed that, but she was gripped in the steamy ecstasy of orgasm, her cunt opening and closing in spasms of joy. Although she wasn't aware of, her asshole sucking at her son's cock, Billy certainly was. He could feel his mother's asshole tightening and sucking at his cock with each fuck-thrust.
Each time Billy thrust his cock forward, Joan met it with a backward lunge of her ass. She began to scream as her orgasms increased in power. Her mind was whirling crazily, and her asshole was on fire.
"Ohhhh, I'm coming!" she screamed, the top of her head now rammed against the couch. "You're making mother come, darling! Making me come with your cock up my hot asshole! Ooooo, fuck that ass… fuck it hard! I love it, Billy! Your cock is so hard in my asshole! Stretch mother's asshole… fill it… come in mother's hot, tight, fucking asshole!"
"I will, Mom!" he grunted. "I will come in your fucking tight asshole! Now… now!"
"Yes!" she screeched, feeling his cock swell, then the hot gush of creamy come juice splashing far up her asshole. The sensation was fantastic, making her come harder than any other time. "Oh, God! Ohhhh, baby! I can feel it! I can feel you coming off in my ass! Ooooo, give it all to me… fill mother's hot asshole with sweet, sweet come juice!"
She pressed his tight balls hard against her convulsing cunt, moaning and screaming with ecstasy.
"That's it." Billy groaned, falling across his mother's back. "I'm finished, Mom."
He wrapped his arms about her, his fingers clawing at her tits. With a soft whimper, Joan spread out, pushing her feet back until her cunt was on the floor. The tip of Billy's cock was caught inside her asshole, and she squeezed it time and again, making soft sobbing sounds of perverse ecstasy.
