Get Brian wasted...

As the boys sat reminiscing, Beth began to enjoy herself by making lewd faces at Kyle that Brian couldn't see. At one point, she even pantomimed a blowjob over Brian's head while giving him a shoulder rub, which made Kyle splutter on his drink. Brian was of course, oblivious.
After that, Beth got a mischievous idea. "Hey Kyle, why don't you answer a question for me. Has your brother always been such a lightweight?" Beth got up, letting Brian fall back awkwardly as she bounded towards the kitchen.
"Lightweight?! I can drink as well as anyone!" Brian protested.
Kyle snickered a little. "Then you've changed since the last time I was home." He sounded amused, and Brian protested again. Beth returned from the kitchen with a bottle of whiskey and three shot glasses.
"There's only one way to settle this: drinking game!"
With his ego and abilities on the line, Brian couldn't refuse. They went round and round, coming up with all kinds of excuses to take shots. Beth begged off after only a few, considering she was already juicy from the bar. But Kyle seemed to have a hollow leg. It didn't take long before Brian dropped like a stone, passing out on the couch with the half-empty shot glass still in his hand.
"Damn..." Kyle swayed a little. "...still a lightweight after all."
Beth tottered over to him. "Think you can carry him upstairs?" she spoke with a low voice.
"Yeah, I can manage."
Kyle was a little more intoxicated than he let on, but he managed to get Brian upstairs without falling down them. While he was gone, Beth wasted little time. She stripped out of her clothes and laid back on the couch, waiting for Kyle to come back down.

"...I think he's going to be fine. Man you'd think he'd have gotten a little....better...." Kyle's words trailed off as he came into the living room.
"Go on..."Beth smiled and kept her tone casual. "You were saying?"
