Unspoken Pleasure (erotica)
Use Your Sisters Instead: EP2

Mary bought a big calendar and tacked it up on the fridge. Then she made each of the girls mark down their cycles so that they could determine their safe days. You'd think she was asking them to choose which finger they wanted to cut off, for all their complaining.

Mary knew better than to ask Michael to be regular about his activities. They would all have to play by ear and figure things out as they went. Fortunately, all three girls lived at home and they all had different schedules with school, extracurricular activities and, of course, church. That meant at least one sister would be available at all times.

With everything set up, Mary wanted to get things started as soon as possible. Fortunately, her son was on the same wavelength. That very next evening, after dinner, she heard music blaring in Michael's room. Her favorite scented hand lotion was missing from her bathroom. All the signs were there. Mary opened the door and, sure enough, there was Michael lying back on his bed. Pants around his ankles. Penis in his palm.

Mary had heard boys liked to look at pictures when they did it, but her son just had his eyes squeezed shut. His body twisted in rising pleasure. He was whispering a word that sounded a bit like 'Tabitha,' but Mary couldn't be sure. Michael's eyes popped open when his mother walked in the room. "Holy... Mom! I told you not to bother me when I'm... When my door is shut."

"And I told you what to do the next time you masturbate," Mary said. She crossed her arms with disdain. Michael lay back, looking shocked. His penis was still in his fist, pulsing and purple.

"Well, come on then," Mary said, "Let's get this over with. Unless you need more time."

"No! I mean. No it's pretty close."

"Good," Mary said, "Let's go replace your sister."

"You mean Tabitha?" Michael asked, hopefully. Mary eyed him warily. One sister shouldn't be any more desirable than another. In any case, Tabitha was at volleyball practice and Hope had a night class. But fortunately Chastity was in her room and almost certainly ready to help.

"Maybe I'll wait," Michael said, "I'm pretty sure Chastity hates me."

"Chastity doesn't hate you," Mary said, "She just has a unique way of expressing her feelings." Michael looked ready to protest more, so she grabbed her son by the arm, dragged him out of his room, and marched him down the hall. "Chastity is going to be so mad," Michael said.

"Of course she won't. If anything, she'd be angrier if you didn't let her help you. You'll see." Mary knocked on Chastity's door (a courtesy she hadn't given her son) and then opened the door.

Chastity was lying back on her bed, reading a book. She was wearing a conservative set of pajamas - red black plaid with long sleeves that almost looked like a little bedroom business suit. Chastity's golden curls splayed out on the pillow behind her.

"What we talked about," Mary said, "It's time." She shoved her son into the room. Michael was completely naked. He kept his head down, avoiding everyone's eyes. He held his erect penis in his hand like it was something that needed carrying. It looked to be about the same size as her husband's, Mary noticed. Perhaps a bit longer and definitely thicker. A very nice penis that would someday give Michael's future wife a lot of healthy babies. Chastity looked up at her brother in shock. Her mouth moved, like she was trying to spin up a sassy retort, but no sound came out.

"Well, get on with it," Mary said. The siblings stared back at their mother. "Must I do everything? Fine. Michael, you said you were close, so get moving. Chastity, take your clothes off. You need to be ready when your brother is, or this will all be for nothing. Don't just stare at me like idiots. This is what we agreed to - get going!"

Michael began rubbing his hand up and down his member lightly. It didn't look to Mary like he was doing much, but she was willing to concede that everyone worked differently. Chastity lifted her pajama shirt over her head. Her large breasts spilled out.

"Holy fuck, sis!" Michael said, "Nice!"

Chastity gave her brother a look - it was supposed to be nasty, but it came out as kind of pleased. Mary had to admit, her daughter's breasts were quite big. Yet they still had the perkiness of youth. Her little pink nipples poked outward. It occurred to Mary that her daughter didn't actually need to take her top off for this, but it was too late by that point. Plus it seemed to be working for Michael. He was rubbing himself much faster. Chastity slid off her pants, then she lay back on the bed.

"Spread your legs a little, honey," Mary said. She stepped forward and pulled Chastity's knees apart. Her daughter's sex was as purple as her son's - her labia hung open and wanting. The strong scent of female arousal filled the room. "You getting turned on by your sister, Perv?" Chastity asked.

"Oh yes," Michael said, like he couldn't hear the insult. His whole body turned red. He was breathing like he'd just run a race. Michael started to rub even faster - completely focused on his sister's naked body. "OK, Michael. When you're..."

"Oh FUCK, I'm going to..." Michael tried to jump forward but it was too late. His semen spurted onto his sister's stomach and chest. He groaned as his body jerked, every ejaculation slowly covering his sister's ample chest. "Ewww, gross!" Chastity said as she was splashed with her brother's sperm.

"You need to cum in your sister, dear, not on her," Mary said, not unkindly, "Don't worry. We'll keep practicing and you'll get it right eventually." She rubbed his head lovingly. Michael looked down at what he'd done. "Sorry," Michael said, "I'm so sorry." He ran out of the room.

Mary glared down at Chastity. "That wasn't exactly what I meant by being supportive."

"It's not my fault he shot his spooge all over me," Chastity said.

"You didn't have to make him feel bad about it, though, did you?"

Chastity got up and started to wipe herself off with a tissue. She sighed. "Stupid, useless brother."

"We're all learning here," Mary said, "I expect you to be more encouraging next time, OK?"

"You mean, like, beg him to stuff my aching pussy with his huge, hard cock until he blasts me full of his hot, sticky cum?"

"Well, maybe not that encouraging," Mary said.

After a little time had passed, Mary went to her son's room and talked to him. She told him that no one was upset. He just needed to learn to time things better.

"With Chastity there naked and watching me. I'm sorry, Mom. I lost control," Michael said.

"I understand honey. And now we know how to fix things for next time," Mary said.

Michael nodded. She thought, for a moment, she saw him smile.

"Chastity is very beautiful, isn't she?" Mary said.

"She's OK."

"And Hope," Mary said, "Don't you think she's pretty?"

"Sure, I guess. They're my sisters. Chastity's so mean and Hope's always being bossy. It's hard for me to think of them that way."

"And Tabitha?"

"Oh, Tabby's gorgeous. Everyone knows that," Michael said.

"Mmhmm," Mary said, "You're a very lucky boy."

"I suppose I am."

After the previous day's debacle, Mary knew she needed to adjust her idea of how things would go. Just randomly selecting a sister in the moment was too complicated. They needed to make the process as easy as possible to start with. Later, once they had a system, they could be less organized about things.

She also decided that Michael may have been right. Mary had no doubt that Chastity would be fine in the long run, but she probably wasn't the best choice for a first try. And if the 20-year old blonde had struggled with doing things right, then starting things off with baby, brunette Tabitha was out of the question. Plus Michael's own reactions to his little sister were a bit troubling. This was supposed to be functional, not fantasy.

So, Mary made Michael promise the next day to masturbate at a certain time. He grumbled and complained but he agreed. Then she made sure Hope would be around at the right moment and ready. Mary told her oldest daughter to wait in her room, already naked. Then she went to Michael and told him he could begin.

Mary waited in the hallway while her son went to work. She thought it would be a few minutes, but a good amount of time passed before she heard her son's door open. He was naked again and cradling his penis the same way he had before. It looked a little larger this time, somehow.

Mary led him back to Hope's bedroom. The tall brunette knew to expect them, so Mary didn't bother to knock. She opened the door and shoved Michael inside.

Much like her sister the day before, Hope lay back naked on top of the covers. She was long enough that her feet hung off the end of the bed. Hope was very thin with tiny, barely-there breasts. Her brown hair was still neatly tied back in a ponytail. Hope was very beautiful - all my girls are, Mary thought proudly - and she could see by Michael's reaction to his naked sister that he found her attractive as well. Despite his earlier denial.
