Lone time of brother and sister

“Oh!” exclaimed Lia, watching the change with delight. “I wonder if it will do it again.”

“Maybe,” said Ben. He eyed the length of his sister’s body, her robe gaping open. “I wonder what would happen if we put our parts together.”

“What?” Lia didn’t understand.

“Our parts. Like the toys we used to play with, where you put the circle in the circle hole and the square in the square hole.”

“Oooooh,” said his little sister, looking down at herself. Then she looked back, creamy liquid still smeared and now drying on her cheeks and chest. “You think that yours fits in my hole?”

“Maybe,” he said. “Do you want to try?” As he asked her he picked up the edge of the robe and wiped off her pretty face with it.

“Sure,” said Lia. Not only was she curious, but she wanted to indulge her big brother. And who knew if their parents would ever go out of town and give them a chance to explore the differences between them ever again. She’d never seen anything like her brother’s boy part, not all big like this.

Although now she wondered if that’s what she felt sometimes when she sat on her Daddy’s lap. He didn’t let her do that as often anymore. Was this why? If so, touching her brother like this was probably wrong, since Daddy wouldn’t let her. But she didn’t care… her parents weren’t home right now to tell them that they couldn’t, so it wasn’t their fault if they didn’t know for sure.

“I don’t think this is the best position to try,” said Ben, looking at the chair. His sister’s wet pink parts were too low for him to stand and too high for him to kneel.

“What do you think would work?” asked Lia.

“Maybe the floor?”

Obligingly Lia got up and lay down on the floor, spreading her slim legs, bending her knees and lifting her cute little butt. Ben got on his knees and rubbed the tip of his penis up and down her wet slit, the same way he had done with his fingers at first.

“Ooooooo,” Lia said, squirming against him delightfully. “That feels weird.”

“Good, weird?”

“Yeah.”

Poking around a little with his fingers, Ben relocated the hole and placed his penis against it, pushing forward with his hips.

“OH!” Lia’s back arched, her pretty little nipples pointing up towards the ceiling. “Oh slow… please Ben, I think it might be too big.”

“No it’s not,” Ben said immediately, his voice hoarse. It felt AMAZING. He’d thought that Lia’s tongue had felt good but that was nothing compared to the tight, wet, hole he was pushing into now. His sister writhed and her insides tightened, massaging, and he thrust forward immediately. Lia let out a small wail, but there was no stopping him anymore, it felt too good.

When Ben was pressed all the way against her, inside of her, Lia grabbed him with her arms and legs, holding him inside of her.

“Wait, wait, wait,” she pleaded. Her insides felt stretched, full, strange. Hot. She shivered, and she could feel her insides clenching, trying to push him out, but her brother wasn’t going anywhere. Already moaning, he was starting to make instinctive little rocking motions with his hips, and even though the stretch of her muscles ached a little, it was starting to feel good again. That internal itch was nagging at her.

Lia’s hips started to rock back against her brothers, and slowly their small movements turned larger and larger. The pressure of his body against hers sent electric tingles through her, and she discovered that she loved the feeling of her brother between her legs, inside of her, pushing against her. It didn’t hurt anymore at all.

The siblings began to hump and moan, the fantastic feelings sweeping through them. They knew very well that their parents would never have allowed them to do that if they’d been home and that knowledge just made the encounter that much more deliciously naughty.

“Oh! Oh Ben! It feels so good!” Lia said between whimpers, her arms and legs clutching at her brother as he heaved and thrust between her legs.

It was fortunate for their experimentation that Ben had already released his fluid all over his sister’s pretty face and body once, or this experiment would have ended a lot sooner and with Lia quite frustrated. Instead, her sweet body started to quiver and she cried out, her insides tightening down on Ben’s penis inside of her as ecstasy and pleasure rolled through her. The unexpected grip of his sister’s body on him was the most incredible thing that Ben had ever felt.

His body shoved forward, burying himself inside of his sister and he swelled up, the fantastic feeling of release shuddering through him. This was the most incredible it had ever felt, the fluid jetting into his sister’s body. He loved her so much.

Ben slumped, lying on top of his sister as both of them painted, both of them overwhelmed by the wonderful sensations that their re-bonding had kindled. Eventually Lia wriggled underneath Ben, complaining that he was too heavy and he obligingly rolled off. His sister looked so pretty, even with fluid leaking down from between her legs. The pretty nipples on her chest were softening and Ben reached out, rubbing his finger over one of them until it got hard again. Lia watched her brother play with her body, the shuddering pleasure that went through her as he touched her made her sore insides feel all hot and bothered again.

“I’m thirsty,” she said.

“Me too, let’s have a snack.”

After all, it was several hours before dinner time. To make his sister feel more comfortable Ben stripped off his clothes and they went naked into the kitchen. They experimented several more times that afternoon, once almost immediately following the first when Lia bent over in front of the fridge and Ben suddenly wondered if he could push into that fantastic hole from that angle.
