Unspoken Pleasure (erotica)
Use Your Sisters Instead: EP3

Hope smiled at her brother and gestured warmly for him to enter.

"It's OK, Michael," Hope said, "I'm here for you." She opened her legs, raising her knees to give Michael easy access to her sex. Michael stood at the end of the bed, penis in his hand. He was stroking it so fast, Mary could barely see his fist. "Are you getting close?" Hope asked. Michael just moaned and nodded.

"When you're ready," Mary said, "Don't wait too long like last time."

Michael stepped forward and lined his penis up with his sister's vagina. He did his best to still rub it as he did. Then, slowly, he moved the head so it was lodged in his oldest sister's opening. She made a little "hmph" noise as he entered her for the first time.

"OH! Wow," Michael said, "Hope. You feel so..."

"Much better than a hand, isn't it, son?" Mary said.

"Incredible," Michael said. His eyes filled with wonder at the pleasure he could feel just from being inside a woman.

"Get it all in there," Mary said, "I don't want any to escape."

Michael leaned forward and Mary saw his shaft disappear into his sister's body. Hope bit her lip. Tossed her head back.

"So good..." Michael said. He reached down to start rubbing his penis again but found there wasn't enough shaft to grab. He looked back at Mary with a sad, confused face.

"Pump her," Mary said, "Just a little. To make your stuff come out."

Michael drew back then pushed forward. Hope let out a deep breath as he did so. In. Out. Two more times. Then suddenly Michael convulsed. His testicles jumped upward. And Mary knew that her son was spending inside her daughter. "Oh YES!" Michael cried.

"MMMmmmph," Hope gasped. Michael stayed in his sister until he stopped shaking. Then slowly pulled back. Mary saw a bit of white liquid leak from the head of his penis.

"NO!" she shouted and shoved Michael back inside his sister. The two siblings stood there, connected, looking at each other almost with wonder. Michael's penis gently pulsed inside Hope. Only after she was satisfied that all of her son's sperm had been left in the proper place, Mary let Michael pull out.

Hope sat up like it was nothing. She grabbed a tissue and held it to her dripping sex. Mary supposed that so long as the sperm was in Hope's vagina initially, God couldn't be too concerned if it leaked out later.

Michael stood over his sister, his deflating penis still in his hand. He was shivering slightly.

"What do you say?" Mary asked.

"Thank you, sis."

"No problem, Michael," Hope said, "Now if you'll excuse me, I have some reading to do for class."

"Excellent," Mary said, "Remember, Michael, if you need Hope again, just let her know, OK?"

Michael nodded, seriously.

Now that everything had gone so well with Hope, Mary was ready to try again with Chastity. As Hope had done, the blonde girl got undressed and then waited for her brother to show up. Michael came into the room soon after, Mary trailing behind him.

Chastity's room smelled strongly of her sex again. She gave her brother a smarmy grin, then turned it sweet for her Mother.

"Try not to blow it, little bro," Chastity said.

Mary thought there was little chance of that. Michael had come out of his room much more quickly this time, and Mary thought his penis looked a bit less primed. But she knew that it was folly to assume that every time would be exactly the same. That's why they needed to practice.

Michael lightly stroked his cock, while Chastity slid forward, putting her open vagina at the edge of the bed.

"Remember Michael, just like with Hope," Mary said.

Michael nodded, then fed his penis into his sister's sex. He didn't stop at the head this time, but instead buried himself to the hilt inside Chastity. Then he started rocking back and forth.

The room was filled with squelching sounds as Michael slid inside his sister.

"Ffffff... She's really tight," Michael said, "Feels so good."

"Better than Hope?" Chastity asked, grinning wickedly.

"I'm sure everyone feels different, dear," Mary said, "But also equally as good. Right Michael?"

"Y... Yes. Oh Yes."

"OK honey," Mary said, "Just go ahead and..."

As if on impulse, Michael's arms shot out and suddenly grabbed his older sister's massive breasts. Mary expected Chastity to scream and slap him, but instead she sort of grunted and let him grope at her. Almost as soon as he touched his sister's chest, Michael's body began to cinch. "Oh... Oh GOD!"

"Is he doing it?" Mary asked.

"Yuh. Oh yeah," Chastity said, "I can feel it spurting in me. I was wrong before. When I said his sperm was icky. It's actually kind of awesome."

"OK, good. Remember not to pull out too soon, Michael." Mary said. Her son nodded as the pleasure washed over him.

Mary thought that would be it for the day, but later that night she heard a knock on her door. When she opened it, she saw Michael, standing there and looking pained. His penis peeked through the doorway. "Oh," Mary said, "OK."

Michael tried to lead her to Tabitha's room, but Mary dragged him back toward Hope's. She knocked on her daughter's door and then opened it.

"Hey, what's..." Hope looked up and saw her naked brother standing behind his mother. Penis at the ready. "Oh! OK, sure."

Hope jumped up and shucked off her pajamas - the same red plaid ones all the girls wore. Then Hope lay back down on her bed, her legs spread lewdly. Michael looked down at his oldest sister and grinned. Without a word, he went between Hope's legs.

Hope gasped as her brother entered her. Michael started pumping right away. Already a veteran. Hope looked over at her mother and made a sour face.

"It shouldn't be much longer, now," Mary said.

"It's not fair," Hope said, "Chastity told me Michael played with her breasts before, but he's not even touching mine. "Michael, play with your sister's breasts."

"Yes Mom. Sorry Sis," Michael reached over and took Hope's tiny breasts in his hands. He tweaked her nipples, too.

"It's OK," Hope said, "I forgive... OH!"

"God Hope, you feel so good!" Michael shuddered and fell forward.

Hope made a long low whine. Her chest and face went cherry red. Her legs kicked out. Twitched. She squeaked out little sounds and her green eyes squeezed shut. Wrapped her arms around her brother's back and shook.

Mary knew her daughter didn't mean to, but Hope was clearly experiencing an orgasm as her brother filled her with his cum.

After it was over, Mary walked Michael back to his room.

"I think we've got this," she told him, "You don't have to come get me every time now. Just grab Hope or Chastity and do what you need to do.

Michael nodded, then leaned down and gave Mary a kiss on the cheek.

"Thanks Mom. I mean... For everything."

Mary smiled wide. She'd really, truly done it.

The next afternoon, a naked Michael ran into the living room like the house was on fire. His erect penis flopped comically as he ran "Mom? We have a problem."

"I thought we solved this," Mary said, pausing her movie. Michael explained that Hope wasn't in her room and so he'd gone to Chastity. But she had told him it was her fertile time. Mary went into the kitchen and looked at the calendar. Sure enough, Chastity would be out of the rotation for a few days.

That meant only Tabitha was left. After everything had gone so well with Hope and Chastity, Mary had quietly decided not to involve her youngest daughter. Now though, it looked like Tabitha was the only option. Mary was glad that Michael had come to her, first.

"I thought it would be best," Michael said. They walked together over to Tabitha's room. Michael's penis seemed not to flag even a little. Oh, to be young again.

Mary went in first and found Tabitha watching a movie on Netflix. The small, brown-haired girl took off her headphones.

"Hi Mom, what's wrong?"

"It's your brother."

"Oh, is it my turn?" Tabitha asked. She quickly stood. "Hope and Chastity told me all about it. I can't wait. I mean, ummm, I can't wait to help my brother."

Tabitha quickly got undressed and lay down in the bed. She really was a mix of her older sisters. She had Chastity's broad shoulders and baby-making hips, combined with Hope's smaller breasts and thinner arms. She smiled, almost eagerly. Then Michael stepped into the room. He'd clearly been stroking his penis while he waited, and it stuck out angrily. He looked down at his sister and gaped.

"God Tabitha. You're amazing. I mean, even better than I... um. Wow."

Tabitha smiled at her brother, warmly. Then she saw what he was holding and her eyes went wide.

"It'll be fine," Mary said.

"I know, it's just... I've never seen one before," Tabitha said, "At least not outside a textbook. It's a little imposing."

Mary didn't want her baby daughter to have a bad experience with this. If it was too much, Tabitha might not do it again and then they'd be down to only two options. As that day had proven, it was helpful to have a third. Even if it was only for emergencies.

Mary knew that Tabitha was very cerebral, so she wondered if explaining things a bit clinically would help her get over the initial shock. Tabitha nodded. She sat up on the bed. Her little breasts - a bit larger than Hope's, but not by much - hung down as best they could.

"Come here, Michael," Mary said. Her son walked up and stood in front of his baby sister. His sex pointed almost right at her mouth. "This is your brother's penis." Mary gestured at Michael's member, careful not to touch it.

"It's also called a cock," Michael said. Tabitha giggled girlishly.

"When he rubs it, it gets hard. Erect," Mary said.

"Uh huh."

"Would you maybe like to touch it?" Michael asked, "You know, see how it feels?"
