A couple of hours later Sally called out to Percy that supper was ready. As soon as the two of them were seated at the table, she said, "Percy, about what happened this afternoon. I just want to say that I know that with a teenager's hormones, sometimes a boy's impulses and... and lusts can get a little out of control. So we'll just chalk the whole business up to that, and we'll never speak about it again. Is that clear?"
Percy smiled innocently. "Sure Mom. Say, that little dress looks really good on you. Is it new?"
Sally was wearing a sleeveless cotton dress. "Um, no. It's just an old summer dress I don't wear very often. I... I didn't have anything else handy to change into."
Percy nodded, staring at the snug bodice over his mother's breasts. "Sorry about your skirt, Mom. I'll pay the dry cleaning bill, okay?"
Sally's cheeks reddened and she avoided her son's eyes. "That's all right. It's hand-washable, fortunately. I certainly wouldn't want to take it to the cleaners with that kind of a stain- Percy, I told you, we weren't to speak about that- that incident again!"
Percy smiled again. "Okay Mom."
After finishing their meal, Percy and Sally were clearing the table. "You know, Mom," Percy said, "I've been thinking that I should start doing more around the house. Like getting supper ready sometimes and things like that. After all, I'm not a kid any more, and with Paul gone some nights I figure I should be acting more like the man of the house."
"Um... that sounds nice, Percy. That's very mature of you."
Percy came up beside his mother and put his arm around her waist. "And speaking as the man of the house, I like how you aren't wearing a bra underneath that dress, Mom. It really shows off the nice shape of your tits."
"Percy, really!" Sally hissed, twisting away from Percy and walking quickly out of the room.
Shortly after Sally had gone to bed that night, Percy knocked on her bedroom door and went in without waiting for a response. "Hey Mom," he said. "We didn't get much time to talk tonight, so I thought I'd come in and say goodnight." He walked over to her bed and sat down, angled to face her. Light from the hall shone across his mother's face and the shape of her body under the sheet.
"Oh, goodnight Per-" Sally broke off with a gasp. "Percy! You're naked!"
"Well, sure Mom. That's how I like to sleep these days, and I figure you've already seen me, so-"
"That's not the point, Percy! You- you're- you have-"
Percy followed his mother's gaze and looked down at his own crotch, where his erect cock was jutting up. "Oh, you mean my stiffy?" He casually wrapped his hand around his hard-on and stroked it. "Yeah, I get like that a lot, Mom. I guess I'll jerk off before I go to sleep."
"Percy, this is completely inappropriate-" Sally's voice faded suddenly when Percy rested his hand on her thigh, caressing her through the sheet and her nightgown.
Percy sniffed the air. "It smells good in here, Mom. Were you playing with yourself before I came in?"
Sally's eyelids fluttered and her parted lips trembled. "Percy, you mustn't do this," she said in a whisper.
With a flick of his wrist, Percy lifted the sheet off his mother's leg. Then he put his hand on her thigh again, his skin now separated from hers only by the fabric of her satin nightgown. "Do what, Mom?" He slid his hand up her thigh until his forefinger was pressed to her pussy, pushing the satin up between her outer cunt lips.
"You mustn't... touch me like that," Sally murmured. "You mustn't be trying to seduce me... To make me want you..." She lowered her eyes to her son's erection. "To make me want you..."
Percy was moving his fingers up and down, massaging Sally's pussy, rubbing the now-wet satin across her cunt lips and clit. "Do you want me, Mom?" he asked.
"No..." Sally whispered. And then, "Yes... No... Yes..." Then she moaned, flexing her stomach muscles to push her cunt down harder against Percy's fingers. "I'm your mother... We mustn't... I'm your mother!"
"Yeah," Percy chuckled as he climbed onto the bed, throwing the sheet completely off his mother's body and lifting the front of her nightgown up above her waist. He put his hand between her legs again, now caressing her bare cunt and sliding his fingers up and down in her wetness. "That makes it kind of kinky, doesn't it, Mom?"
"Oh god," Sally whimpered, closing her eyes. Her arms were out straight at her sides, her hands closed into tight fists.
Continuing to stroke his mother's cunt with one hand, Percy used his other hand to lift and move her legs one at a time so they were spread wide. Then he lay down on his stomach between her thighs, shimmying down the bed so that his face was over her pussy and his legs were dangling off the end of the bed. "I'm just going to kiss you goodnight, okay Mom?" he said, and moving his hand away from her pussy, he lowered his face until his pursed lips touched lightly on the slick pink pearl of her clit. He pressed down, made a smacking sound and lifted his face again. "Just a little kiss goodnight, right Mom? There's nothing wrong with that, is there?"
"Oh," Sally sighed, lifting her belly towards her son's face. "Oh Percy. Oh my gods."
Percy was grinning. "Another kiss, Mom?"
"Please, Percy. Please don't."
Ignoring his mother's words, Percy lowered his face again, this time extending his tongue and pressing it down along Sally's cunt and clit, opening his mouth wide to get as much contact as he could between his lips and tongue and his mother's pussy. He pushed his face down until his nose was buried in the soft, tickling nest of her pubic hair and then curled his tongue forward, slipping it up into his mother's cunt and inside her body as far as it would reach. A long, sighing breath came from Sally's parted lips.
For several minutes Percy kept his mouth tight to Sally's cunt. He lapped at her, sometimes using the flat of his tongue to make broad, luxurious caresses, other times teasing her relentlessly by giving her clit delicate, whisper-soft flicks with just the tip of his tongue. At still other times he would close his mouth around the upper part of her pussy and suck on her, drawing her clit up into his mouth. On and on he continued, working endless variations between his tongue and mouth and her clit, cunt lips, and pussy. Through all of this, Sally said nothing, only moaning and whimpering as she writhed on the bed, turning her head first one way and then the other, occasionally reaching down to her son's head to run her fingers through his curly black hair.
Finally Percy lifted his head from between his mother's thighs, wiping her juices from his face with his hand.
"Oh, Percy sweetheart, don't stop," Sally moaned. "Please, I need just a little more."
Percy was already sitting up on his folded legs, holding his rigid cock in his fist. "How about we do something else for a while, okay Mom?" he said.
Sally lifted her head up from her pillow, looking down at her son's cock. "Are you going to fuck me now, Percy? Are you going to put your cock inside me?"
"Yes Mom," Percy said softly. "I'm going to fuck you." Sally's nightgown was still bunched up at her waist, and he lifted it up her body. "Let's take this off, Mom."
Without speaking, Sally sat up and lifted the nightgown over her head. As she lay back down she spread her legs wide and propped herself up on her elbows, gazing down at her pussy and her son's cock, now almost touching. Percy leaned forward over her, reaching out to one of her big, soft breasts, fondling it and then releasing it after a moment to do the same with the other. Then he leaned back again and took his cock in his fist, bending it down so that the head was pointed at the entrance to his mother's cunt. He shifted forward slightly, and his cockhead came into contact with the warm, wet pussy. He moved it around in circles, getting the head slick with her juices.
Then Percy shifted forward again, and the first inch of his cock disappeared inside his mother. Sally gasped sharply, her eyes wide and fixed on the place where her son's body and hers were joined. Percy slid another inch in, and she gasped again. "Oh Percy," she said. "Oh, my beautiful son, my gorgeous boy... I've wanted you for so long. Even when you were little I used to think about taking you to bed, spreading my legs for you, showing you how to put your hard little thing inside your mother..." She paused to take a deep, trembling breath as Percy began moving his cock back and forth, sliding the first few inches in and out of her. "And now... now you're a big, beautiful boy, and your cock is huge... A huge, wonderful cock to fill up your mommy's cunt!" She brought her arms forward so she was no longer supporting herself on her elbows and lay back, at the same time reaching out to put her hands on Percy's hips. "Put all of your cock inside me now, Sweetheart. Lie on top of me and give mommy all of your cock!"
Percy did as he was told, leaning forward and lying full-length along his mother's body. As he did this his cock slid deeper and deeper inside her, until he was buried to the very root. "That's all of it, Mom," he said, his face hovering above hers.
Sally lay frozen, her mouth open but no breath coming from her, she stared up into her son's face with her eyes wide and glazed. Then suddenly she moved convulsively, throwing both arms around Percy's neck and pulling his head down, mashing his lips against her own. In this position of frenzied, spasmodic kissing, Sally began to scream, as much as a woman can scream when her mouth is sealed tight to another mouth. The sound was muffled and high-pitched and ragged, interrupted occasionally by desperate, gasping breaths through her nose, and was accompanied by a shuddering and twitching of her body. Over and over she thrust her pelvis upward as if hoping to take still more of her son's cock inside her, and again and again she clutched and pulled his body against hers, her hands slipping across the skin of his back and buttocks.
Sally stayed in her spasming stasis of orgasm for an endless, timeless span. Then, finally and suddenly, she relaxed. Her arms fell back beside her body and her head dropped into her pillow and then lolled to the side. Her mouth was open and slack and her eyes were half-closed and focused on nothing.
Percy braced himself up on his arms to look down at his mother. "Wow, Mom," he chuckled, pumping his cock in and out of her cunt at an unhurried pace. Several seconds passed with no movement or response from Sally. "Mom?" Percy said. Holding himself up with one arm, he put his free hand to her face, turning her head toward him. Still Sally seemed almost lifeless, her breath gurgling in the back of her throat. "Mom?" Percy said again, more loudly. "Are you okay Mom?" With his hand holding her chin, he gave her head a shake, and then another shake
