Brandon stays till the climax

Lisa and Brandon knelt in the kitchen, down low enough to look over the breakfast bar while being mostly hidden from the pair in the living room. "Stay," she said, her hand on his shoulder. There was a pleading look in her eyes.

Brandon hesitated, looking at her eyes. His prominent erection throbbed out from the leg hole of his shorts. His face glowed with heat, from anger at Zack and Madison, from guilt at getting turned on from watching them, and shame at his hard cock sticking up at Lisa.

Madison's voice rose in the next room. Brandon's head whipped round to look over the top of the bar. Madison was holding tight to Zack's shoulders, her head tilted back as she rose and fell on Zack's cock. Zack cupped her buttocks, one finger on Madison's ass.

Brandon was transfixed, watching Zack's cock sliding in and out of his sister. Madison's butt, tight from cheerleading and martial arts, barely jiggled as she rode Zack's cock. Brandon's mind replayed the night Ashley had done that with him, including that finger on her ass. His middle finger tingled in recollection as he watched Zack touch Madison in that same way. His cock twitched as he remembered Ashley riding up and down on him, grinning at him, winking, sticking out her tongue, pausing and wiggling her butt back at his finger, then riding again.

Brandon heard Lisa's quick breathing beside him. Lisa's hand moved down from his shoulder to rest on his lower back. And quieter than Lisa's excited breathing, Brandon heard a rhythmic squish-squish-squish as she fingered herself. "Zack," Lisa whispered. Lisa was remembering her own time riding Zack the same way.

Madison settled down on Zack's cock and started rolling her hips, rocking into him. "More," she said. "Your finger."

"Yeah," Zack said. "Wow. Oh."

Inside, Brandon thought. Zack's finger is up my sister's butt.

"Ahh," Madison said. "Yeah, yeah, like that, ooh." She spread her knees, putting more of her weight on Zack's firm pubic bone. "Yes yes yes!" she said, pressing hard into him. "Yes yes yes, oh, oh, OH!"

"Oh!" Lisa breathed out. Her fingers dug into Brandon's lower back. The little squish-squish-squish sound was louder and faster.

Madison's lithe, petite form strained against Zack as her climax took her. "Eeeeeeeh!" she whined as her hips pumped, grinding her clit into him.

"Mmmmmhhh!" Lisa moaned.

Brandon looked. Lisa's face was screwed up in a grimace. She trembled against the kitchen counter, one hand pressed hard to her pussy, the other hand gripping Brandon and holding him against her. Brandon felt hot all over. His cock twitched. His balls tingled.

"Oh!" Zack groaned. "OH!"

"Ooohhh," Lisa sighed.

Brandon looked round to the pair on the couch. Madison was rolling through another wave of orgasm. Zack's shoulders were quivering. Brandon's cock pulsed, on the edge of eruption. He gritted his teeth and held his lips tight closed, his breath coming fast through his nostrils.

Zack's balls twitched, his cock root swelled, and he shot a load into Brandon's sister.

Brandon's cock erupted, spurting against the cabinets behind the breakfast bar. He closed his eyes tightly. A wave of heat swept over his body. As his climax ebbed, he opened his eyes again.

Madison was sitting on top of Zack, resting her chest against his, her dark-haired head leaning on his shoulder. Zack's cock was still inside her. Threads of white seed oozed out of Madison's cunt and down Zack's balls.

Unprotected, Brandon thought. His stomach twisted with worry, but his cock twitched with excitement.

As the glow of the orgasm faded, Brandon's knees started hurting. He slumped down behind the breakfast bar and turned to look at Lisa. Her eyes gleamed intently at him. He couldn't read her expression.

"Support them," Lisa whispered.

Brandon nodded. "Yeah," he said.

"I'm glad you stayed," Lisa said.

"Yeah," Brandon said, not sure if he agreed. "Gotta go now."

Lisa smiled. "Thanks."

Brandon stuffed his wet cock into his shorts and sneaked off to the bathroom.

Lisa looked at the wet tracks Brandon had left on the kitchen cabinets. She smiled and shook her head. Boys, she thought. She quietly made up a wad of paper towels and wiped up after him.

She stared a while at the last pearly drop, then leaned forward and licked it from the cabinet. Brandon's cum, slick and salty, reminded her of Zack's.
