Sure, Mom. Let's go back to bed. We can talk there." He started to lift Sally's bathrobe off of her shoulders, but she quickly pulled it back on.
"No Percy!" Sally said sharply. "Not now. I need some time to think about... about what we did."
Percy kissed his mother on the neck again. "Oh come on, Mom. What we did was great! You loved it and I loved it, so what's the problem?" With one arm tight around her waist, he reached into the opening of her bathrobe with his other hand and began fondling her pussy.
"Percy, no." Sally's voice was softer now, and she made only half-hearted attempts to push her son's hands away. "Percy, please..."
"You're really wet already, Mom." Percy pushed a finger into his mother's cunt and brought it out again, using the coating of slick fluid to slide his fingertip over and around her clit.
"Percy..." Sally murmured. She reached around behind herself until her hand found Percy's cock, and she gasped as her fingers closed around it.
Percy once again lifted the bathrobe off his mother's shoulders, and this time she offered no resistance. She released his cock and held her arms at her sides, letting the robe fall to the floor. As soon as she was naked, Percy pressed his body to his mother's back, his hands sliding over her stomach and breasts, his cock upright between her buttocks. "Can we fuck here, Mom?" he asked. "I've always dreamed of fucking you while you were bent over the kitchen counter."
A shiver rippled through Sally's body. "Oh, Percy... You shouldn't talk that way... I'm your mother..." Then she bent low, thrusting her ass back and planting her hands on the counter in front of her. "Like this, Sweetheart? Is this how you want me?"
"Oh, fuck!" Percy whispered. He rested his left hand on his mother's ass, caressing the taught, smooth skin, and with his right hand he took hold of his cock, aiming it at her glistening-wet cunt. Then, without pause or hesitation, he pushed it into her up to the hilt.
Mother and son cried out in unison; she with a desperate "Oh, god!" and he with an inarticulate groan. Percy leaned over Sally's back, bringing his hands up under her to hold and fondle her breasts. He pumped his cock into her, making long, slow strokes. At the same time he kissed her neck and upper back, sometimes bringing his face up beside hers and extending his tongue to lick her ear. "I love you, Mom," he whispered. "I love having my cock in your sweet, wet cunt!"
After staying hunched over his mother for a time, Percy straightened up, fucking her cunt faster and harder as his excitement increased. "Such a beautiful ass!" he said, stroking one buttock. Then he brought his hand up and put his thumb in his mouth, wetting it with saliva. A moment later he was rubbing the ball of his thumb over the opening to his mother's asshole. He pressed in, and his thumb popped inside her up to the first knuckle.
Sally sucked in a breath and her head jerked up, her back and neck arching. Her hands on the countertop closed into fists. "Oh Percy!"
"You like that, Mom?" Percy worked his thumb back and forth in the tight grip of his mother's anus, gradually pushing it deeper.
Sally whimpered wordlessly, her breath coming in quick, ragged gasps. Then she reached a shaking hand out across the counter, to a ceramic butter dish that was against the wall. She lifted the cover off the dish and then slid it back across the counter until it was close beside her, in a place where Percy could reach it easily. "Percy... Please..." she said.
Percy looked at the butter and his eyes went wide. "Wow... Really, Mom?"
"P- please, Sweetheart," Sally said. She was staring straight ahead at the wall in front of her.
Grinning, Percy pulled his thumb from his mother's ass and pawed at the softened butter in the dish, scooping off a generous dollop. Working his thumb and fingers together, he spread the butter over his hand. Then, pulling his cock halfway out of his mother's cunt to make room between her ass and his belly, he slipped his hand into that space and pushed his middle finger into her anus as far as it would go.
Sally groaned, low and throaty, and groaned again as her son began moving his finger in and out, rotating his wrist and bending his finger to stroke the inside of her.
"Beautiful!" Percy said. "Beautiful, beautiful ass!"
"Percy," Sally panted. "M- more. Please. Not... just... your finger..."
"I know, Mom," Percy chuckled. "I was just leading up to that." After one slow, final thrust, he drew his cock out of her cunt, at the same time taking his finger from her ass. Then he wrapped his buttery hand around his cock, stroking and twisting to make sure it was well lubricated from tip to base. He held the head up to the crinkled sphincter of her anus and said, "Here it is, Mom. Here it comes," and started pushing. At first his cock made no headway, but he held the shaft tight in his fist and increased the pressure, leaning his weight forward. Finally his cockhead slid past the tight opening, and the rest of his entire length quickly followed, disappearing into his mother's bowels.
Sally let out a bellowing, shouting cry. Her knees buckled, causing her upper body to drop down onto the countertop. She laid like this, her legs limp and useless, her face resting sideways on the counter, moaning rhythmically as Percy began to make hard, violent thrusts into her asshole.
"Oh, fuck!" Percy groaned. "So... fucking... tight!" With each word he slammed his pelvis forward, pounding his cock deep into his mother. He slid his hands up her back and gripped her by the shoulders, pulling back on her to meet his jolting thrusts. For long minutes he kept up his rough ass-fucking, manhandling his mother's small body in a blindly instinctual drive to force his cock deeper and deeper inside her. Finally his motions reached a frenzied peak, and he croaked out, "Gonna come up your ass, Mom... Gonna... fucking... come!"
As if on cue, just as Percy began pumping his semen into her, Sally's head snapped up, and from her wide-open mouth came a long, continuous wail, while at the same time a shuddering spasm shook her body and her arms jerked and twitched at her sides.
Some unknown time later, Percy's eyes blinked open. He was lying across his mother's back, the two of them draped over the kitchen counter. "Wow!" he breathed, lifting his chest off of her. "Are you okay, Mom?"
Sally made only a soft moaning sound. She planted her hands on the counter and slowly lifted her head and chest. She started to stand up but then stopped. "Percy... you... you're... you're still inside me."
"Oh, yeah," Percy chuckled. He stepped back from his mother, slowly drawing his half-hard cock from her gripping anus. As his cock dropped free, there was a gurgling sound and a flow of semen began trickling down the back of Sally's left thigh.
"Oh, god," Sally said. She quickly put a hand across her bottom and, wobbling unsteadily on her feet, trotted awkwardly out of the kitchen and toward the bathroom.
Percy was sitting in the living room when his mother came home from work that afternoon. He jumped up from his chair and went to her. "Hey Mom!" he said, and started to put his arms around her.
"Percy, stop!" Sally snapped.
Percy stepped back, startled and frowning. "What now, Mom?" he said.
"Percy, I've decided that this - what we were doing - it's over. It's over and we will never speak about it again."
"Aw Mom, Come on-"
"No!" Sally folded her arms, staring down at the floor as she spoke. "What we did... what you did was wrong, Percy. It was wrong and disgusting, and it showed a complete and utter lack of respect for me." She lifted her head and glared at her son. "I mean really, Percy... that you would do... those things... to your own mother!"
"But Mom, you wanted it!"
"That's completely irrelevant, Percy. If you had any respect for me as your mother, you wouldn't have... done those things. As she spoke, Sally's hand drifted back toward her bottom.
"Is this about the ass-fucking, Mom? Because if that's what bugs you, we don't have to do that any more-"
"Percy!" Sally barked, her face reddening. She took a breath before continuing in a controlled voice. "You see what I mean, Percy? You will never have any respect for me as long as... as long as things like that are a part of our vocabulary. That's why it has to stop."
"No I don't see, Mom. I respect you. I respect you and I love you, and the fact that we have sex doesn't change-"
"The topic is closed, Percy. Go to your room. I'll call you when supper is ready."
Percy sighed loudly and thrust his hands into his pockets. "Supper's all set, Mom. I've got some macaroni and cheese in the oven."
