Not with a bang, but with...

Madison set up the timer on her phone. The girls waited with excitement and curiosity at what was about to occur. Taylor still gazing at the two cocks in front of her started taking off her shirt, and said "Alright Ashley, whenever you're rea-"

Gagging filled the room. "Gyack! gyack! gyack!" Taylor turned around to see Ashley practically shoving Kurt's fat cock down her throat while jerking off a patient Gavin. Kurt had his head back and his arms spread over the back of the couch, a big smile on his face. Gavin looked like he was enjoying himself, but he also looked like he didn't know where to look, glancing from Ashley, to Brandon, to the girls, and back again. Madison immediately started the timer and placed it on the counter so that it could be seen from almost anywhere in the room.

Taylor glanced at the timer, before focusing her attention on the two guys who were supposed to be off limits on this trip. Zack like Gavin looked around not sure where to focus his attention, he was still rock hard, his lower half ignoring the current situation. Eventually he focused his attention on his older sister, waiting for the inevitable.

Brandon looked at his girlfriend deepthroating a monster cock ten feet away from him then back at Taylor. He knew Ashley had been cool with, and even turned on by him being blown, and decided to use what she does as a reference for what he could get away with.

Taylor hesitantly reached forward wrapping her hand around Brandon's cock. Her left hand rubbed against her little brother's cock and it twitched. She took a deep breath and wrapped her fingers around the long 11 inches. She followed Ashley's lead and engulfed Brandon's thick schlong while she began jerking off Zack.
