Brandon accepts and he and Taylor watch side by side.

Brandon had nothing to say. Taylor came back with a handful of paper towels. Nice ones, thick and soft. Madison was riding Zack's cock in the deck chair, rising and falling, letting out little giggles and moans of pleasure. Taylor stood next to Brandon, watching Zack and Madison moving against each other out in the dark.

"Hannah and I had the same talk about Ashley," Taylor said. "She didn't think Ash should go steady with you. That Ash was too impulsive, letting her cunt make decisions for her. I told Hannah she should butt out and give it a chance. I was right. Was I right, Bran?"

Brandon's cock swelled. "You were right," he said. "Hannah was right too." I'm Ash's sex toy, he thought.

"Oh, oh, oh!" came Madison's voice from outside. The sighs and giggles from earlier, when they were making out, had turned into panting and moaning.

"It's not always bad to let your cunt make decisions," Taylor said. "Or your dick. But you kind of need to lay out some boundaries. Know what you're doing. So here at the cabin, you're giving Madison a chance to make that decision."

"Yeah," Brandon said. "I was worried for her. I still am."

"I'll make sure my brother doesn't hurt Maddie by being stupid," Taylor said. "Talk about stupid. Today he walked into my room through a sock on the door when I was busy." She sniffed in annoyance. "For a few days, here, we can keep an eye on Zack and Madison."

"Madison, she," Brandon said. "I found out she was watching me and Ash."

"So maybe she's working out some jealousy," Taylor said. "Feeling like it was unfair that you and Ash were at it like busy bunnies. And now it's her turn."

"Yeah," Brandon said. "Can't stop her."

"So we're supporting Madison getting what she wants," Taylor said. She leaned closer and whispered in her low, sexy voice, "Getting what Ashley has. Dick. And we're here to celebrate it by watching."

"Uh," Brandon said. "Uhhhh." He looked down and to the side. Taylor had pulled up her nightshirt and had a hand moving between her legs.

"Celebrate," Taylor said.

Brandon looked out at his sister riding Zack's cock. It was too dark to see anything more than shapes, but he could imagine every detail from what he'd seen earlier. Zack's big cock spreading Maddie's pussy, her pussy lips dragging in and out as she pressed deeper and rose higher.

"Yeah," Brandon said, stroking his cock. "Yeah. Get it, Maddie."

"Yes," Taylor said. "Feels so good. Can I put an arm round your shoulders?"

"Yeah," Brandon said.

Taylor circled an arm around Brandon's shoulders. Zack's sister was tall and long-limbed, so it was no strain. The two of them stood side by side, touching themselves, listening to the couple on the deck as they rose toward their peak together.

"Oh, oh, oh, oh Zack I'm..." Madison called out.

"Yes, Maddie, yes," Zack said. "Oh Maddie I'm...AHHHH!"

"OH OH OH AHHH!" Madison cried.

Brandon's cock erupted and he cried out, "AHH-hppt!"

Taylor's hand, slick with pussy juice, was clamped across his mouth, stifling his cry. She held Brandon tightly around his shoulders with a hand on his mouth as his cock spurted into the handful of paper towels.

When Brandon relaxed, Taylor took her hand back. Taylor's musky cunt scent was strong in his nostrils.

Taylor said, "We better go. Thank you for letting me hold you. And you better wash your face. Sorry."

"S'ok," Brandon said. "'Night."

The living room was dark and quiet when Zack and Madison tiptoed back in.

"Hope we didn't keep anyone up," Zack said.

"Everyone was in bed," Madison said. "It was all dark."

They hugged each other tightly in the middle of the dark room.

"Thank you, thank you, thank you, Zack," Madison said.

"I never knew," Zack said. "Thank you for, um."

Madison giggled. "Seeing your dick out and jumping on it."

Zack shook his head and laughed quietly. "Yeah. But next time let's get a room."
