He caressed her pussy-lips gently, the light touch shooting fierce waves of pleasure through her and producing vigorous undulations in her hips.
She moaned happily. "Oooh, that feels good, Son! Mmmm!"
He ran a fingertip around the rim of her cunt hole and she grabbed a taut stocking in each hand and pulled furiously.
"Oh!" she gasped. "Oh, Danny!"
His fingers left her for an instant, and then she felt them stripping back the hood of her clitoris.
"Mmmm!" She bucked violently. "Aghhh!"
He coated the tiny organ with thick juice from her cunt and began to rub it. She lost all control of her actions, thrashing in her bonds and moaning loudly. The pleasure that flooded her was so intense it hurt, and a vast hunger grew in the mouth of her pussy. While Danny continued to massage her clitoris with the fingers of one hand, those of the other returned to her cunt-lips.
"Don't get mad, Mom, but… Well, this was one of the centers." He plunged a finger into her hole, twisting it back and forth and jabbing it in and out.
"Ohhh! Ahhh! I'm not… mad! It is one! Oh, Danny! Son! Ram it hard!" He jammed the finger in to its knuckle.
"Use… use two! Maybe three! Omigod, Son! Oooh!"
She felt a great increase in fullness and knew Danny had inserted more fingers in her box. She slammed her cunt onto his hand repeatedly, her pleasure driving her past caring how she looked to him. She became aware of slippery strokes over her bung.
"What's… that?" she panted.
"My thumb, Mom."
"Oh."
His thumb paused over her tightly closed asshole and pushed. She felt her sphincter stretching to admit it and tilted her head back.
"Danny! Aghhh!" she cried out and let her ass flail on the hugeness of his buried thumb. "My God, Son! Omigod!"
"I got stuff up your vagina and your ass, Mom." His voice sounded hoarse to her. "It sure makes you move around!"
"God yes! It's going to make me have an orgasm!"
"Yeah? Really?"
"Mmmm! Yes!"
"Mom, he said the biggest stimulus of all was… well…"
She gazed groggily at her son. He stood erect, both hands hidden behind the forest of her pussy hair, his enormous cock jutting over her. The shaft pulsed and there was a strand of clear mucus dangling from the angry-looking slit in the head. His crotch hair was black and thick and she recalled with a shiver the great size of his balls. Suddenly she realized what he was hinting.
"No, Danny! Not that! No, for God's sake!" But why not? she asked herself in a flash of recklessness. Why not? That's part of it! "All right, Danny! Go ahead! He's right."
Danny trembled violently as he withdrew his hands. He seized the huge shaft and guided the head down to her cunt mouth. His face expressed wonder as his heat and hers mingled and her cunt began to open to his pressure. She felt the head sink through the firm rim of her pussy-lips and glide slowly up the length of her cunt, the hard shaft stroking inward after it. She thrust herself onto the intruding prick, her butt quivering and tight and her belly hard.
"Ahhh!" she bubbled with joy. "Ahhh!"
Her son's hips surged forward to drive his prick to its limit in her hole, and his pelvic bone slammed onto the outer flesh of her pussy. He jerked his hips back, withdrawing the buried cock until the head lay just inside her gash, then rammed it home again. She cried out and flung herself onto the driving prick. Her son's thrusts accelerated and he banged violently at her.
"Mom! Mom! I can't stop!" A deep note of panic rang in his voice and he had an anguished expression in his face. "Mom! I didn't mean to! I just wanted to see what it did to you! I didn't mean to fuck you all the way!"
She soothed him with gentle urgency. "It's all right, darling! It's all right!" She saw the depth of his distress and urged him. "Fuck me, darling! Go ahead and fuck me! It's all right, Son!"
His cock slammed back and forth savagely and her cunt flamed. She felt as if the shaft were crushing her tissues against the bony circle of her pelvis and his cockhead were displacing all her organs. His anguish had cleared, replaced by ecstasy, and his hands kneaded her waist and pulled her butt against his thighs.
"Yes, yes, darling!" she panted.
"Mom! Mom! Here it comes! Unnnh!"
His cock-shaft pulsed sharply and hot jism seethed into her cunt filling her belly with foreign heat. She clamped the rim of her cunt on his cock, squeezing with hard contractions and praying for her own orgasm. Danny broke into convulsive tremors and the great cock went limp and soft. He pulled it out instantly, great drops of sweat pouring from him.
"Mom!" he murmured brokenly and came around the table to hold her face. "Oh, Mom, I'm sorry!"
"Danny, baby," she whispered. "Oh, Danny! How did it feel, Son?"
"Jesus, Mom! Like nothing I ever felt before!" He grinned bashfully. "You got awful excited, didn't you."
I still am! she thought. She nodded and smiled. "You found all the spots, Son. There's still a lot to learn, though."
"There is?"
"Yes. Maybe I'd better teach you while all this is fresh in your mind."
"Would you, Mom?"
"Yes. You might as well untie me now."
"You know that was kind of fun. Having you tied up, I mean. I like that."
"Well, maybe I'll let you do that again sometime."
"Oh, Mom! Would you! Please?"
"Yes."
"Promise?"
She laughed and hard thrills raced through her. "I promise."
"Wow!" Danny shouted.
He untied her quickly, and she went back to the bathroom where she douched and washed. As an afterthought, she sprayed herself with her best cologne. When she returned to the front of the house, Danny was sprawled in an armchair in the living room. He glanced up at her entry, astounded at her continued nakedness.
"Time for more of the lesson," she said with mock formality.
"What are you going to teach me now?"
"Let's demonstrate instead of talk. Okay?"
"Sure."
She stretched herself along his body, straddling one of his thighs to let its hardness ease the hunger of her pussy, and put her arms around him. "Kiss me again, Son."
Their lips locked and her tongue probed for his. He explored her throat with his tongue tip and she writhed on him, her boobs scrubbing the sparse hair on his chest, her cunt grinding on his thigh. When she drew back to look into his face through a film of happy tears, she knew he was no longer Fooled by the academic pretense.
When he spoke, his voice had a tone of new maturity. "Mom," he said very softly. "You just want to fuck with me, don't you?"
She cringed. "Yes," she whispered. "I didn't until it happened, but I do now. Besides, there really are a lot of things you don't know yet."
"Yeah." He kneaded her ass and sighed. "I've dreamed I was fucking you lots of times. It never did turn out like today." A faraway look of bliss stole into his eyes. "Never wild like that was. Mom, the second I stuck my cock into you I knew I couldn't stop! I knew I had to go all the way!"
"I know."
The telephone rang. Helen groaned and scrambled off her son. "Why don't you get it, honey? You've got to get your blood circulating again."
"Okay," he grinned, laying his hand on her belly for a moment before leaving her. In a moment, he was back. "Dad," he said. "Says there's an emergency meeting with the State Highway engineers tonight. He called from the airport to say he'd be home the middle of tomorrow morning."
"Oh, dear!" she wailed.
Danny grinned. "Hey, Mom! We can play a lot! Okay?"
She realized how such a suggestion would have horrified her two hours earlier. "A regular orgy, you mean," she said dryly.
Danny grinned and ducked his head. "I guess so. All kinds of games."
"Yes. I guess we can do that."
"Wow! Gee, thanks, Mom!" He grabbed her, pulling her to him and rubbing his body against her jugs. He slid his hand down her side to her hip, then around her and between her thighs to clutch at her pussy. She squirmed, but his other arm was like a bar across the small of her back, and he dug his fingers deeply into her crotch, raising her feet from the floor. "This is fun, Mom! I like playing with you like this!"
