Lexie smiled, nodding. Okay, no restaurant, she would just wait for a break in conversation to use the bathroom. "Something to drink sounds awesome," she said, as she got comfortable on the couch. "So do you cook, or are you just going to order something?" She asked, making conversation.

"We'll order something." He replied, as he gave the glass of water to Lexie.
The water of course had sleeping pills in them, which would at the very least, make Lexie drowsy and suseptable.
"So what do you want to order?"

(Sorry for he cliche.)

(Not a problem. I love cliche. And since Lexie has a very low bodyweight, I think the pills will be plenty effective.)
Lexie wasn't sure what to pick. She wanted to make sure she wouldn't accidentally order something he disliked. "Uh... How about pizza?" Everyone likes pizza, right? Nervously, she looked for something to do while he responded. Water. Good. She brought the glass to her lips, drinking most of it quickly.

"Yeah sure." He replied grabbing the phone to order.
He watched intently as Lexie drank the water. They would take effect soon.
Alastair quickly ordered one large meatlovers pizza and hung up.

Lexie was relaxed on the couch by the time he was done with the order, blinking drowsily. I wonder if I can shut myeeyes for a minute while he's on the phone... no, he's done.
"Um... How does coffee sound?" She asked. "I could use a mug right now..." she blinked and yawned, trying to keep her eyes open.

Alastair smirked, knowing why she wanted the coffee.
"A bit early for coffee isn't it?" He said, putting on a smile.
Alastair sat down next to Lexie. He didn't make any attempt to talk knowing that it would only make Lexie more awake.

Lexie nodded a bit, blinking slowly. "I... guess..." another slow blink, then this time she just shut her eyes.
He won't mind, will he? It's not like I'm gonna sleep, or... anything...
Then again, maybe just a few minutes of rest to perk me up for the night...
But... I...
Zzzzzzzzz...
(So you know, unless you wake her up beforehand she'll wet in her sleep in about 25 minutes, give or take.)

Alastair smiled as the girl finally fell asleep. He picked her up with ease, cradling her in his arms and carried her into the spare bedroom.
He lay her down on the changing table and removed her panties. He pulled out a diaper and began fastening it around her waist.
He then carried her back down stairs and waited for her to wake.

Lexie woke up twenty four minutes later, very groggy but her toilet training kicking in before she completely lost control. She felt like she could sleep for a month, but her bladder was bursting to go.
Wait... what's wrong with my panties? They felt strange. Thick. Bulky. Plastic. But why was it familiar?
She looked over at Alistair. "Um... did I fall asleep?" Crossing her legs to hold in the pee, she felt the thick crinkle again. What was that? "I... where's the bathroom?"

Alastair watched as the girl awoke. He could see that she was busting to go. If he could just stall her a little longer he would have her.
"Yes you did fall asleep." Alastair said. He needed something else to say. Something to make her wait.
Just at that moment there was a knock at the door. The pizza had arrived.
Alastair smiled. "Wait right there, while I get the pizza." He said.
