Peter grunted even more excitedly from his aunt's unexpected response, increasing the length of his own piercing lunges until he was unleashing the full fury of his lust with a series of mighty thrusts deep into her still wildly contracting anus. At the same time, he shoved his middle finger deep into the quivering softness of her cunt and increasing the friction of his thumb's rapid stroking over her little twitching clitoral bud. Already he could feel the cum begin to well up in his balls and he knew it wouldn't be long now until he lost all control. But his aunt was really beginning to respond and he was determined to hold off as long as he possibly could.
Marilyn's body was really coming to life now. The contrasting sensations in her two simultaneously ravished cunt and asshole had begun to merge. She could no longer clearly distinguish between the pain and the pleasure, and her nakedly squirming body shuddered as the waves of delight began to course in swift overwhelming tingles out over her lust-contorted flesh. In spite of all the inherent humiliation in the "dog fashion" posture and the sheer degradation of the depraved act of sodomy, she was responding! She didn't have to fake it – she wanted it! Peter's throbbing young penis ramming up into her sensitively pulsing depths of her rectum was breaking down her will to resist and she screwed her buttocks back hungrily against the surging shaft of flesh that invaded her, longing for more and more of the lewdly masochistic titillation.
Behind her, Peter groaned as he felt her anus contract even tighter around the lunging shaft of his cock. He knew he was hurting his aunt, and he was trying to hold himself back, but the obscene triumph of watching her wallow in masochistic bliss before him, not to mention the sheer intensity of sensation, were more than he could stand. Trying to compensate for the pain with an even more frenzied stroking of his finger over the little quivering bud of her clitoris, Peter began to ram into her clasping rectum with even more violent force.
"Oooooohoooooh! Agggggghhhhhhhh!" Marilyn moaned before the frenzied assault, her body thrashing beyond control from the obscene sensation coursing through her loins and rectum.
Gasping, Peter slacked off, reclining his weight heavily against his aunt's upthrust buttocks, his cock buried to the hilt in the rubbery tightness of her rectum. He flexed, sending another wanton shiver coursing the length of her softly perspiring body.
"I'm sorry," he groaned, "I'm hurting you."
"No," Marilyn gasped, trembling beneath the boy's sagging weight. She grunted as he flexed again, then turned her head to look back over her shoulder, and the lust-contorted expression on her face was like nothing Peter had ever seen in his life. "No," she whimpered again. "I like it. I like it. I want you to fuck me."
Peter could hardly believe his ears. He remembered all the time he'd spent dreaming of doing this to his aunt, trying to work up the courage to ask her and now she was telling him that she loved it, she wanted more of it, she loved it.
"Yes," Marilyn groaned as Peter began to move again. "Fuck me, fuck me harder, fuck me harder!"
Again Marilyn dropped her face down onto the pillow, her buttocks jerking and waving in complete submission as Peter resumed his youth-driven fucking, his cock swelling even larger in her burning rectum as the cum surged in his balls and began its mad dash up the blood-stiffened rod.
Again she rocked backwards, taking the lust-inflamed hardness even deeper, screwing her buttocks in a passionate rotating motion. She knew she was going to cum any minute now, and she strained and fought desperately for her own release. She hovered on the brink for what seemed like an unbearable eternity; yet still it eluded her, and now Peter was running out of time.
"Finger-fuck me harder," Marilyn gasped in sheer desperation. "Fuck your middle finger harder into my pussy. Make me cum too."
As Peter slammed down on his aunt's helplessly writhing body with an even mightier racking stroke, he slipped his middle finger eagerly into the softly parting lips of her already lewdly moistened flesh, worming it up into the unresisting softness until it was buried to the knuckle in her vagina. Wiggling it deep inside her, he began to finger-fuck swiftly in and out as he felt the last of his own control fading and the cum surged up hotly from his balls and began to splatter in thick squirting droplets deep up in the clasping tightness of her rectum.
"Yes," Marilyn purred as she felt the boy's shattering lunges becoming even more intense, the obscenely shooting sperm that filled her rectum further lubricating the tight orifice until the pain faded almost entirely, replaced by the sheer pleasure stimulation of the shocking sensation that was now completely meshed with the wanton tingling in her cunt.
"Yes, yes," she moaned deliriously as she felt the waves begin to build in her own body. "Yes, and do my clitoris too. Do my clitoris with your thumb."
Peter willingly complied, and moments later the devastating contortions began to flow at swift relentless intervals through Marilyn's ravished body. She sobbed without restraint from the shattering waves of ecstasy coursing through her rectum and loins, bucking wildly beneath Peter's final racking lunges.
With a last grunt Peter sagged back tiredly on his aunt's still trembling buttocks, feeling the little spasms continue to shake her body for several moments longer. Then his lust-spent penis began to deflate up in her cum-filled rectum and he withdrew softly and rolled over tiredly on his back.
Slowly Marilyn turned to look at her nephew, gently caressing his young face as she gazed into his dark brown eyes. "You satisfy me so Peter," she purred, "you seem so much older than eleven."
"You bring out the best in me, you really do," he said quietly, feeling suddenly very grown up.
"I liked it Peter, I thought I would hate it, but I liked it, but I want this to be our secret, just you and me, I don't want the other boys knowing about this."
The young boy readily agreed, happy to have something special to share with his aunt, something that none of the other boys had.
The satiated couple lay staring at the ceiling for a long, long time, finally drifting into a light sleep, locked in each other's arms, safe within the confines of their secret special love.
CHAPTER SEVEN
"Marilyn, I have to tell you, that it's just beyond me, why on earth did you allow those boys to fuck you in the first place?" yelled Ronnie Goodge, beside himself with rage after having discovered the fatal tape in his son's bedroom only an hour ago.
"I was lonely, I don't know how it happened, except that Peter came to me to tell him about the facts of life and we just ended up doing it. Oh don't yell at me Ronnie, I'm scared enough as it is," sobbed Marilyn.
"You should be Marilyn, do you realize what will happen if the police find out?"
"No!"
"You'll be imprisoned, that's what, I still can't believe it."
"What can we do?"
"There's only one solution. I've been thinking about it for a while anyway and this clinches it. I've been given a promotion. If I take it it would mean that I'll have to move to Cincinnati immediately. Marilyn will you come with me. We could live together and no one would know we weren't married."
"What!" the startled woman cried out, her mouth dropping open in amazement.
