“Yeah, you lean against the headboard and I’ll sit here.” Caoline moved onto the bed and sat cross-legged near the foot. Her pussy was exposed and Carl’s prick, which had been softening, twitched. He leaned back against the headboard and lightly stroked his returning erection, his eyes on Caroline’s pussy. She chuckled softly. “I thought it might help if I sat like this.”
“It does, sis, it does. Your pussy is beautiful.” Wet, too, he thought, sure he could see moisture.
“Thanks, bro. It’s wet, too.”
“I can see.” Carl stroked his hardness, grasping it lightly, then winced slightly as his hand caught on the dry, hot, skin.
“What’s up?” Caroline asked, concerned.
“I need lubrication,” said Carl. About to spit on his palm, he paused. Caroline was staring at him, hunger on her face. “What?” he said.
“I have lots of lubrication,” she whispered. “Carl?”
“Yeah?”
“Will you be my warm dildo, let me fill my pussy with you?” He could hardly hear her husky croak.
A shock of desire ran through him. Mute, he nodded, his prick feeling as if it was trying to get even harder. Caroline smiled, a sweet, warm, smile and moved to her knees, shuffling forward astride Carl’s legs. She rested her hands on his shoulders and leaned forward to kiss him. Her lips were soft, warm, and the kiss was friendly, a siblings’ kiss.
Caroline broke the kiss and reached down between them. She took a gentle grasp of his prick, positioned him carefully and then lowered herself onto his hardness. Carl groaned, feeling the hot, wet grip of her pussy on his prick, enveloping, heating, hardening. He reached up to cup her breasts.
“No, don’t!” she gasped. “If you don’t touch me I can pretend, pretend that I’m just using a pleasure tool.”
He groaned, and she gave him an absent half smile, her face absorbed as she moved herself on his hardness. It was warm in her bedroom, and there was a sheen of sweat on her face as she moved. She was wet inside, too, and Carl was hypnotised by the liquid slither of Caroline’s pussy as it moved easily the full, hard length of him. He pushed to the back of his mind any thought of this being wrong. He was helping his sister, he told himself, that was all.
Caroline was excited, and she was revelling in the feel of Carl’s prick in her pussy. You feel great, Carl, she thought, absolutely great. And you’re gonna make me come, soon. She adjusted her angle slightly, trying to make it so that Carl’s prick rubbed her just so, giving a soft little moan as she felt the first faint indication of approaching climax. Damn, she thought, I’ve never come this quickly before, abandoning herself to the feelings, letting the heat rise in her until with a strangled cry, half moan, half scream, she came.
Carl was watching the expressions on Caroline’s face with fascination, enjoying the fact that he could make his sister feel this good; enjoying too the pulsing clamp of her pussy on his prick as she abandoned herself to the moment, her head thrown back, her eyes closed.
The voice when it came startled them, both with the fact of it and with the anguish in the tone. “What on earth are you two doing?” Judy Muller’s voice trembled as she stood in the doorway, staring at her children.
Caroline cast a startled, apprehensive look over her shoulder, but Judy was gone, fleeing the vision. Caroline quickly eased herself off Carl’s prick. “Quick, we have to see her, explain.”
“Explain? How? How the fuck do we explain incest?”
“I don’t know, I’ll think of something. Come on.”
Carl rolled off the bed and followed Caroline, the two of them still naked, Carl’s prick hardly softened, for he had yet to come. They found Judy on the couch in the living room, her face strained. Caroline went to her knees in front of her mother and took her hands. “Sorry, Mom,” she said.
Judy gave an empty laugh, almost a sob. “So you damn well should be, committing incest.”
“No, Mom, I’m not apologising for that, I’m apologising for the fact that you caught us. Why aren’t you at work?”
“Never mind why, what do you mean, you’re not apologising for screwing your brother?”
“Just that, Mom. I’m sorry you caught us, but we weren’t exactly screwing.”
“Ha! It looked like it to me!”
Caroline smiled gently. “I was taking advantage of Carl and using him as a living dildo. Mom, think about it. Isn’t it better to have a nice, warm, hard prick with a gentle man attached, one you’re fond of, rather than a cold dildo or your fingers? It’s just a different form of masturbation, don’t you see?”
Judy half smiled. “And just when did you think that one up?”
“Just now, when I saw Carl’s prick erect for the first time.”
“And when did that happen?”
“Out by the pool. Mom, do you know what day it is today?”
“The fourteenth. What difference does the date make?” Judy was puzzled. She didn’t buy Caroline’s story, but she was prepared to listen while her daughter tried to explain herself.
“It’s National Nude Day, Mom.”
“National Nude Day! You’re kidding me!”
“No, Mom. I read it in the paper and managed to persuade my bashful brother to strip, too. Goodness knows, we’ve tried to peek at each other often enough. I thought, hell, it’s National Nude Day, so why not let’s see what we’ve been hiding from each other. I guess the sight of me finally naked excited Carl, and he got a hard on. It looked so pretty I asked him if he would be my substitute dildo. Well, you know what men are like, Mom, he wasn’t going to say no, was he? And I guess that’s where you came in. Why are you home, anyway?”
“There was a power cut. Some no-brain took a drill through the circuit. The estimate was evening, so the boss sent us home.” Judy gave a short laugh. “And what do I find? My kids screwing each other.”
“Not quite, Mom, although I have to say, having felt Carl’s prick in my pussy, if he wanted to offer me a friendly fuck I’d find it difficult to say no.”
Listening to this, Carl felt his still more than half-hard prick twitch in excitement. Shit! If Carly was telling the truth, he’d make the offer as soon as he could catch her alone. Caroline caught his eye and grinned. She does mean it. Wow!
Caroline gestured. “Look at it, Mom, isn’t it pretty? Doesn’t it give you naughty thoughts, too?”
Carl flushed scarlet to find himself scrutinised by his mother but instinctively he knew not to hide himself. Whether it was the unblinking look with which Judy regarded him or not, Carl felt his prick stiffen a little more.
Judy turned away, reluctantly, Carl thought. She gazed at Caroline for a moment or two, then nodded. “You’re right, it’s very pretty, and yes, it does give me naughty thoughts. Naughty thoughts which I have no intention of acting on. It’s incest for goodness sake. A crime!”
“Lunch, Mom?” said Caroline, abruptly changing the subject. Seed sown, she thought.
“Just a sandwich, I think. And don’t think that by changing the subject you’re going to make me forget what I caught you doing, young lady. You, too, Carl. You know it’s wrong.”
“I guess so, Mom,” said Carl.
“You know so.” Judy stood. “Are you two going to get dressed?”
Before Carl could answer Caroline shook her head. “No, Mom. It’s National Nude Day, remember. We stay naked. In fact, why don’t you join us?”
“Don’t be ridiculous! Okay, stay naked, but you can at least help me make sandwiches.”
Lunch was a quiet affair, and the twins kept a low profile. They had slipped robes on while they ate, a slight concession to convention, but after they had finished Caroline led Carl out to the pool again and they discarded the robes. Carl was relieved that his prick had finally softened in the fuss of lunch and Caroline was greeted by an only half-hard prick when Carl discarded his own robe.
She looked up at her brother, grinning. “Did I think quickly enough? For Mom, I mean?”
