Day 3
Shannon woke early, planning to spend more time dressing Sean. The abs on Sean's body flexed as she sat up easily. She stopped to admire the view down her front, and flexed her pecs a few times. She listened carefully for any noise from Sean's room, then she pulled her shorts down to get the full monty.
She stared at the semi-erect penis, about 2/3 of its ultimate size, and wondered how much it changed as boys walked around in various situations. She had heard most boys were only 5 to 6 inches erect, so Sean had been somewhat blessed, although she had no idea if he was thicker than the norm as well. She tentatively reached out and ran a finger up and down the side of it. The smooth, taught skin was very sensitive, she thought. It had grown a bit more now, pointing straight out. She pushed down on it to see how that felt. It didn't hurt much unless she tried to push hard. It would easily go upward against her stomach, though.
Her experiments now had it fully erect, 7.5" long and standing up at 45 degrees with a swollen head. In imitation of countless males over the centuries, she tried to bend forward and touch it with her tongue, but fell short by several inches. She laughed to herself and watched it shake a bit.
She listened again for any noise in the house, it was still dead silent. She wrapped one hand around the thick rod, and squeezed it. That felt better than she expected, not hurting at all. She cupped the hairy scrotum, also more sensitive than expected. She squeezed it a bit harder and the sharp pain surprised her. The line between pain and pleasure on the scrotum was apparently very fine. She rubbed it more carefully, feeling the testicles move around under the strangely bumpy skin of the sack. She shifted to the shaft again. Her heart was beating harder now and her mouth felt strange. She slowly moved the clenched hand up and down, feeling the dry friction on her skin, watching and feeling the skin stretch up and down with her ministrations.
"These things are kind of fun," she thought. She gripped the base with her left hand and the upper half with her right, the width of the two just less than her length. She held it like that for a few moments, then she moved her hands together, trying to imagine what it felt like fully inserted in a vagina. The dry skin of her palms spoiled the fantasy, though.
She turned to her bedside table and pulled out a tub of hand cream. Listening all the while for Sean, she took a dollop of the cream and spread it out on her penis, making it twitch, slippery and glistening. She grabbed it with both hands again and rubbed them as one. That felt pretty good, she thought, too bad I'll probably never stick this in a girl for real. She took the left hand off and continued to stroke with the right. That felt even better, so she stroked harder, altering the stroke to get a better feel as the hand rubbed up onto the mushroom head.
The head was getting very sensitive now and a tingling feeling was running down the rampant penis. She stroked faster and moaned softly. Her left hand moved below to cup her balls again. She squeezed a bit too hard and felt pain, so she tried pulling down on them gently, which felt good. She stroked harder with her other hand and kept caressing her balls. "Ahhhhh," she groaned, and the tingly, burning feeling gathered at the base of her rod and shot upward, come spurting onto her stomach and chest. She was surprised at how fast she could achieve orgasm and far the semen shot out. It usually took her quite a bit longer to masturbate in her own body. Her new knowledge made her a bit more sympathetic to Tony's quick shot, though she could not condone his actions afterwards.
Suddenly she remembered Sean was in the house, and held her breath to listen. It was still quiet, so she tentatively stuck a fingertip into a gob of semen, then stuck it in her mouth. It smelled a bit but didn't taste like much. She imagined swallowing it like Erica and shrugged. Then she hopped up and quietly walked to the bathroom with the slowly wilting penis waggling before her, leading her into the shower.
After the shower Shannon looked into her wardrobe with a critical eye. She was going to dress to impress today, so she wanted a good outfit for Sean to show her off in. She finally decided simpler was better, and chose a black ruffled skirt that would show off her legs and a deep blue blouse that made her hair look even redder than usual. Sean would have to shave her legs, at least the lower parts anyway. Due to the black skirt against her very white skin, she tried to find a decent set of pantyhose to wear, but they were all old and worn since she had not been dressing up for over 6 months. She thought about switching to pants, but that seemed boring. She finally dug into the back of her lingerie drawer and pulled out a new pair of thigh high black stockings she had never worn before.
"I hope he can handle wearing these, they should stay up ok without a garter," she thought. Slightly higher platform style heels finished the outfit.
Shannon went into Sean's room to find him buried under blankets, just some random strands of red hair sticking out. She sat down on the bed and shook him. "Sean!"
"What?"
"You need to get up a little earlier, remember? I'm dressing you up a little more today, I promised Mom."
"Uhhh. I was hoping I'd be me again this morning."
"Me too. Do you think I like waking up each morning with a stiffy? It's really strange. And you have calls of nature twice as often as I'm used to because your body eats so damn much. And I'm always hot, not in just the good way, but just plain overheated. Why are you under all those blankets?"
"Because your body is always cold, especially at night!"
"Aww, poor baby! Rise and shine, I have an idea to get you shaving and showering in general without keeping your eyes closed."
"What?" His head popped out of the blankets.
"Ta da!" She held up a white bikini.
"Brilliant!"
They headed into the bathroom. "I think you could just get away with the lower legs and knees, the skirt is not that short."
"Um, ok," he replied.
"Ok, same drill." He closed his eyes and took off the t-shirt and shorts and panties. She put the bikini bottoms on one leg, then the other, and he pulled them up snugly. "Arms out." She fastened the bikini top, "Ok."
He opened her eyes. "If you want to leave, I'll get to it."
She walked out, and he closed the doors and quietly locked them for the first time in 3 days. He looked back over his shoulder to admire the view of Shannon's ass in the hi-V-cut bikini, then he turned slowly to get the full show. He wasn't sure he could ever get used to seeing this every morning, it was better than his stash of playboys. If only he had his dick to stroke...wait, not for his sister, but...face it, he realized, she was so hot it was useless to deny the fact that she turned him on.
He got in the shower and dropped the wall bench to sit on while shaving. The hot water had Shannon's soft skin ready in no time, and he started to apply the gel and rub it into lather. "Hmmm, that's not bad." He decided to keep going, the feeling getting more intense as he rubbed lather up over his inner thighs to the edge of the bikini. Squirming toward the end, his whole body was getting flushed. He ran the razor carefully down one firm calf. Ok, that was not hard.
He was done with her legs in a few minutes. They felt great when he ran his hands along the baby smooth skin. He could feel some warmth beneath the bikini. The feeling grew more urgent, so he pulled the bottoms down and took a peek. His sister's landing strip had widened a bit with fuzz over the past 3 days. With her body encouraging him, he decided to clean it up. It would save her the effort if they switched back tomorrow, or something like that, he rationalized weakly.
