Tom Allison - The teacher_s incest urge

She was too immersed in fucking Mark's prick. In and put it went, filling her cunt with every stroke. Betty gasped and bowed her head as she lifted her ass for more.

They'd been fucking together for almost a week now, at school and everywhere else besides, and she just couldn't get enough of him. Her teenaged English student was the best lay she'd ever had!

Both of them were totally naked, sweating profusely as they fucked. Betty's enormous jugs swung freely back and forth, the fat, stiff nipples brushing the sheets of the bed every time Mark rammed his cock into her pussy.

"I'm cumming now!" Betty squealed. She felt the familiar delicious spasms churning through her cunt, making her pussy muscles suck Mark's pumping prick. "Awwwww, yes! Fuck me! Fuck meeee! Cumming!"

Betty came extremely hard, gasping and whimpering as she squatted on her hands and knees on the mattress. When she came to, Mark was still hunched behind her, relentlessly hammering his cock through the hair-fringed mouth of her cunt.

"Oh, Mark, that was wonderful!" Betty sighed. A nervous smile spread across her face. Mark had made her cum so hard that she felt helpless, despite her thirty-seven years. "You fuck me so beautifully. I love the way your big dick…"

Suddenly Mark pulled back his hips, withdrawing the ten cum-soaked inches of his cock from her cunt. Betty felt the bloated knob twitching between the cheeks of her ass.

"What are you doing, darling?" she asked, tilting her head back to look at him. "Did you cum? I didn't feel…"

"I didn't cum!" Mark said hoarsely. "I want to fuck your asshole."

An instinctive tremor flashed through Betty's body, making her stiffen as she knelt on the bed. Asshole fucking was the one thing she'd denied her late husband. She'd never been screwed that way before, and for a moment the idea disgusted her.

But the mood passed quickly. Betty had changed a great deal in the past several weeks. Her fuck sessions with her two high school students had made her hornier than ever before. Her pussy was wet constantly, like a bitch in heat. For the first time, Betty realized that she might enjoy having Mark's gigantic prick boring into her little asshole.

"All right, Mark," Betty whispered anxiously. "But do you… know how to do it? I mean, I don't want you to hurt me or anything."

"I don't think you got anything to worry about," Mark said. "Shit, I've been butt fucking chicks since I was a young kid! Just reach for that little jar on the nightstand."

The little jar on the nightstand was Vaseline. Without changing her position, Betty grabbed it and handed it over her shoulder to Mark.

"Don't worry about a thing, Betty," Mark said soothingly. "You just leave it all tome."

Unscrewing the cap from the jar, Mark withdrew a thick clump of the jelly and tossed the container absent-mindedly onto the sheets. He carefully coated the shaft and knob of his enormous prick with Vaseline, until it was completely covered with the thick, viscous cream.

"Spread your ass cheeks," he whispered. "I want to fuck your asshole."

Blushing with embarrassment, Betty reached behind and dug her fingers into the plump cheeks of her ass, splaying them as wide apart as she could. Mark smiled and stared hungrily at the puckered pink asshole. Her ass muscles clenched in and out in her wanton excitement.

Mark applied the remainder of the Vaseline to Betty's asshole. Skillfully, he darted his slick finger into the rubbery grip of her anus, coating the insides of her tunnel.

Betty felt a strange pleasure course through her asshole, making her nipples and her already dripping cunt tingle madly with hot lust. She sensed that she might enjoy this, that her asshole might welcome the invasion of a big cock like Mark's.

"Now, just relax, Betty," Mark murmured huskily. Lifting the blue-veined stiffness of his dick, he fit the fat knob carefully to her asshole ring. "Lie flat on your stomach and don't worry about a thing. Most chicks really dig getting fucked up the ass."

Feeling like a little girl, Betty stretched out on her stomach and shut her eyes. Mark came gently forward, imbedding the spongy tip of his hard-on in her asshole.

Betty felt the pleasure instantly, shooting warmly through her ass tunnel, moistening her cunt, making her ass muscles pulse madly. She enjoyed it already! She wanted Mark to ram his huge cock all the way up her hole!

"Is that okay?" Mark gasped.

"Yeah! I really like it. More, Mark. Stick your dick in harder!"

Mark pushed his hands under Betty's torso and grabbed her enormous tits for support. Then he rhythmically began to buck his hips, slowly hammering the length of his thick prick into the rubbery grip of her asshole.

Betty felt every inch of his cock going in. Her asshole muscles stretched around the width of his dick, creating a filled up sensation unlike any she'd ever had.

It hurt, but very little. She was so horny that her asshole opened up easily around his monstrous cock. Betty grunted and hotly lifted her cunt up off the bed, thrusting her blushing ass cheeks back over his dick.

"Oh, Christ, is your ass tight!" Mark whispered. Halfway inside her asshole, his prick was incredibly stiff. Betty could feel it throbbing and jerking violently in the clasping suction of her asshole. "I never – unh – fucked a girl with such a tight ass before! Oh, fucking Christ!"

"All the way in now!" Betty squealed excitedly. Clawing the sheets, she humped her ass back onto him as fast as she could. "Fuck me, Mark! Fuck me, Mark! Fuck my asshole! Unh, unh, unh!"

Mark reared back, withdrawing his prick until only the knob parted her asshole. Betty could feel cum oozing out of his dick head, mixing luridly with the Vaseline that now seemed to cover everything. Then, grunting lustfully, Mark rammed his cock savagely inward, burying all ten inches balls-deep in the rubbery grip of her asshole.

For a second, Betty could hardly stand it. Painful spasms racked, her asshole as her tunnel helplessly tried to accommodate itself to the size of Mark's enormous prick. She felt stuffed by his cock, and a second later she felt as if it was boring through her stomach and coming out of her throat.

"Is that okay?" Mark asked thickly. He squeezed her huge tits and gently rocked his hips, thrusting his throbbing cock slowly through her ass.

"Unhhhhh," Betty moaned. As Mark fucked her ass, she felt the pain gradually diminishing, being replaced by the most intense pleasure she had ever known. Her asshole was throbbing around his pumping prick now, pulling it deeper into the depths of her ass.

"It feels good now," Betty whimpered. "Fuck me hard!"

Squealing uncontrollably, she began to gyrate her hips in a shameless frenzy of lust trying to pull even more of his dick between her jiggling, reddened checks.

"Fuck me now – Mark! Oh, yes, yesss, that feels so good! Fuck my asshole! Fuck meeeee!"

For nearly a minute, Mark stroked slowly. Wincing, he withdrew his pulsing cock nearly all the way out before stabbing it back in again, sighing as he felt her rubbery asshole muscles clench, his cock.

Then he started fucking her harder. The bed shook with the strength of their humping. His lean, sweaty stomach slapped wetly against the pillows of her ass cheeks as he plowed his heavy dick into her. Mark pulled on her nipples and began to ream out Betty's asshole as fast as he could.

"Ahhh, Mark! Fuck me haaard!" Betty shouted. Again she reached behind her and spread her ass cheeks, desperately struggling to get more of his bloated prick between the pink, puckered muscles of her hole. "I'm gonna cum! Oh, God. I'm gonna cum soon! Unhhhh, yes, yes, fuck meeeee!"

"Finger your cunt," Mark whispered hoarsely. "Unh! Go ahead, play with yourself! It'll make it better. Jack your pussy off!"
