Chapter 3B

Megan's head came up and her book went down. "What?" she responded.

"Well, some of the classic paintings of all time are of two people... a man and a woman... together..." She didn't want to actually say "naked" in this situation.

Megan's voice sounded like she needed to clear her throat. "You mean me and... Robby... together?"

"Well, yes, that's what I was thinking." said Valerie.

"But you're not finished with this painting are you?" asked Megan.

"No, but I can work on several paintings at the same time. That's no real problem."

"Oh." Megan appeared to be thinking. "What kind of painting?"

"Oh... well... maybe something like 'The Love Of Souls', by the Belgian painter Jean Delville. Here, I think I have a picture of it in this book." She went to a shelf and pulled down a thick book that was full of pictures produced by well known artists over the centuries. She thumbed through it until she found what she was looking for.

"Kind of like this one, though I might pose you a little differently. These people are standing, and I'm thinking of a couple reclining."

Megan peered at the page. "But mom, they're naked."

"Well of course they are dear. That's the point. It's the anatomy that's being displayed and highlighted."

Megan looked up at Robby, who hadn't moved and hadn't said a word. He stood there, his prick rock hard, pointing at both women. He didn't know what to say.

"What do you think Robby?" she asked. The thought of her body up against his, naked, touching. That thought made her feel hot all over.

"Um... well... I don't know." he finally said in defeat.

"OK. Let's do it." said Megan, as if she had actually received information and made a decision based on that information. "What do we do first?"

Valerie hadn't realized Megan would agree to posing with her brother so quickly, and she was caught off guard. She looked around. She didn't have a love seat for them to recline on, and in her mind's eye she wanted the female's back facing the viewer. She stepped up to Robby, who was still standing like he had been posed, still erect. She had to move him to one side, her hands slipping over his oily body. "Move dear." she said and he stepped to one side. She moved the pillar and found a tarp.

She turned to Robby. "Go down in the basement. Over in one corner there's a mattress and box springs that used to be in your room before we had to get you a longer bed. Bring up the mattress."

Bobby came to life and stepped down off the dais, his prick bobbing up and down. Both women watched it and watched as his hand caught it to stop it from bobbing.

Fresh juice seeped into two pussies.

When he got back, his sister was naked. He'd tried for years to peek at her, wondering what she'd look like without clothes on. He had a picture in his mind of her, but it was off in several particulars. First of all he visualized her as plump, and short, but she wasn't plump at all. Her slim form looked like almost any of the models in the magazines he often looked at. Her breasts rode high on her chest, but they weren't big and round, like his mother's. Instead they were more like cones and they came to points that were darker pink than her skin. Her nipples were different than the girls in the magazines. They were puffy, and he really couldn't differentiate the nipples themselves from the areolas that surrounded them. His eyes dropped to her thighs and he saw her nest of light colored hair.

She was blushing under his examination, but made no complaint.

He was glad he had the mattress in front of him, because his cock was leaking stuff again.

Valerie turned around. "Good. Put it up there." She pointed to where he had been standing, and where the tarp was now spread. Once the mattress was settled the way she wanted it, she draped a maroon colored sheet over it. Then she had him lie down on his left side, with pillows bunched up under his armpit, which raised his upper torso off the mattress. She had Megan lie facing him, against his body, her right arm up and out, making a pillow for her head. Valerie draped Megan's left arm across his waist. Then she took Robby's right wrist and had him rest it on Megan's hip.

She stood back, looking at the scene. "Robby, bend your right knee and put your foot on top of your left knee. I want your knee standing straight up." He did and she liked the look. "OK, now Megan, turn your face down a little, like you were sniffing his left armpit or burying your face in his chest."

There was nervous laughter from the teens. But Valerie liked the pose. "That's good. Now pay attention to how you're lying, because this is what we're going to do for a while."

Megan was out of her element. She had thought it would be fun to be next to her naked brother. She hadn't thought about what she would actually feel when his skin touched hers. And she was mildly freaked out that his penis was touching her too. Right now it was sandwiched between their stomachs and she could feel the hot column of stiff flesh where it pressed against her. There was also something tickling the hair on her mons, and she realized it had to be his balls.

"This is weird" she said softly to her brother.

"Do you want to quit?" he asked her, leaning back a little.

"No." she answered. "Mom wants to do this, so let's give it a chance." She pulled with her left hand and he rolled back against her. For some reason she felt better about the emotions that were flooding through her if she thought she was doing this for her mother.

"Sorry about the... " he whispered.

She knew exactly what he was talking about, even though he couldn't bring himself to say 'erection'. "No, it's OK" she said. "You feel warm."

"Thanks." he said.

"No problem" she said to his armpit.

He felt her breath there and suddenly felt uneasy about what that armpit smelled like. "Um... to I need to put something on that armpit?" he asked. "To make it smell better?"

Megan thought about that and realized that she hadn't registered the odor she had been breathing in for the last few minutes. She paid attention to it now and realized she liked it. "No... you smell... I don't know... OK I guess." She had been about to say he smelled GOOD, but she was to embarrassed to admit she liked his manly scent.

There was a subtle change that took place in the teens over the next half hour they posed. Being in such close proximity to a naked person of the opposite sex, while being new to both of them, rapidly became something they both decided they liked - a lot. And, the feel of flesh on flesh brought on, in each of them, a natural tendency to... rub. The first thing they each moved was their hands, caressing each other without even being aware of it.

"Don't move your hands." ordered their mother, who was extremely pleased that, for the last half hour, she hadn't once thought of her son's strong, hard penis, and had paid attention only to her art.

Then Megan found herself pulling her brother harder against her. His skin felt good on her breasts, and his penis felt REALLY good against her stomach, for some reason. When he felt it he reciprocated. It felt just as good to him.

Finally Valerie told them they had posed long enough, and that she had enough sketched in to do some background work. "You two can go do whatever you want."

When they rolled apart Megan looked down at the thing that had been pressing into her belly and her eyes widened as she saw a string of almost clear... something... stretched between her body and the tip of his prick.

He looked down too. "Sorry" he whispered. "Sometimes it leaks a little. It'll wash off."

Megan felt her whole body shiver as she realized what that stuff must be. Her pussy, which up to now had only been feeling warm and nice, suddenly got wet.

Robby picked up his robe, but didn't put it on. Megan picked up her clothes, but didn't put them on either. They left the studio together while their mother dabbed at the canvas, ignoring them both.

"I need a shower" said Megan, rubbing her finger through the precum he'd deposited on her stomach.

"Yeah. Me too. I'm all oily." said Robby.

They walked down the hall together. "It wasn't so bad" said Megan.

"Yeah." said her brother. "You can go first."

Megan went in the bathroom while Robby headed for his bedroom... and some badly needed relief. While he 'flogged his log', thinking of his sister, she squatted in the shower and crammed two fingers in her as deep as they'd go. She had the sweetest cum of her life as he spurted, not twenty feet away.

Then, drying off as she went, Megan went to her room. The first thing she did once she got there, was take one of her birth control pills.

As Megan swallowed the pill, a series of muscular events took place. Her throat muscles forced the pill down to her stomach, which flexed as it realized something had been deposited in it. Associated organs produced digestive fluids that were forced into the stomach. Her arm and hand movements were involved too. With all those muscles moving, Megan never felt the twitch inside her as her left ovary squeezed an egg into the attached fallopian tube. The egg, as if it hadn't a care in the world, drifted in the tube, slowly making it's way toward her uterus.

As for Valerie, she slumped when her two children finally left the studio. Just after she so proudly noticed she hadn't thought of her son's penis for a while, she couldn't stop thinking of it. Seeing them there together, in so intimate a pose, she had mentally placed herself in Megan's place, pressed against Robby's strong, wide chest, his penis... his HARD penis pressed into her groin. She'd sketched on autopilot, but now her hands were shaking. With an anguished moan she undid her pants and slid her hand into them, mauling her pussy until she felt the sweet release of her orgasm.

"Oh what am I going to do?" she asked herself as she pulled her wet hand back out and stared at it. She knew she needed to get laid, and she needed it badly. But Phil wouldn't be back for months yet, and she'd never even contemplated cheating on him before. While she thought about what to do about her itch, she went into her bathroom and took a birth control pill.

The next morning all three of them were up before nine. Valerie made breakfast, mostly out of habit, since her mind was still on how she could deal with her recent upwelling of lust. Megan walked in next and sat down to a plate of bacon and eggs. She looked tired, but happy somehow. Before Valerie could ask how she'd slept, Robby stumbled in. He looked haggard, like he'd had a hard night.
