Sam was in the middle of taking a shower when he heard the doorbell ring. He poked his head around the curtain and eyed Ainsley. She was dressed in one of his dress shirts, and brushing her teeth.

"Can you put some pants on and answer the door?"

Ainsley threw Sam a look over her shoulder but smiled around her toothbrush. She spit toothpaste out of her mouth and headed for the door.

"Ainse,"

She turned around and Sam was still sticking his head out of the shower. He beckoned her over and Ainsley obeyed. Sam cupped her cheek in his hand and kissed her. Ainsley moaned against his mouth and went to wrap her arms around him as she kissed him back. The kiss became intense and Sam went to pull Ainsley closer to him but succeeded in pulling the shower curtain down. Sam slipped and fell against the wall, Ainsley coming with him.

"We're the two klutziest people on the face of the Earth." Sam mumbled against Ainsley's neck. She gave a sigh as she ran her fingers through his hair.

"You pulled the curtain down." she reminded, kissing his temple. The doorbell rang again and jolted the couple back to reality. Sam sighed, remembering there was someone impatiently trying to get into his apartment. He looked at his girlfriend, the white dress shirt clinging to her small frame as they still stood under the water from the showerhead and let out a tiny moan.

"I wish they'd go away."

"We still have to go to work."

"Not for a while." Sam pulled Ainsley back for one more kiss and she relented. "I'll go get it."

"Okay. I'll take a shower then." Ainsley peeled the shirt off her and tossed it onto the tiled floor.

"What about the curtain?" Sam quickly pulled his undershirt and boxers on.

"Just lock the door on your way out."

Sam nodded and closed the door as he left, then headed down the hallway. He opened his front door and his jaw dropped, seeing who was standing there.

"Hi!" Sarah jumped Sam, hugging him tightly.

"What are you doing here?" Sam pulled his younger sister off him and stared at her. "Oh my God. You're not pregnant are you?"

"No! I just came to see you."

"Why aren't you at school?"

"It's a nice place you got Sammy."

"Sarah..."

"I may have gotten kicked out."

"Sarah, how do you get kicked out of Princeton?"

"Well gee Sam, not everyone is like you." she snapped. "I hopped on the first train to DC."

"Why didn't you go home to Mom and Dad?"

"They wouldn't be too happy."

"You think I am?"

"I need a place to stay."

"No."

"Sam..."

"Sarah, no."

"Come on!"

"I said no!" Sam exclaimed. "You need to go home."

"They will be so pissed though!"

"Sar, you can't stay here. I'm busy and have a life."

"It's only for a few days. They'll send a letter to the person who paid for the tuition, which is Dad, on Friday and then I'll leave."

"I... Sarah, I can't believe you." Sam muttered. She sighed and ran a hand through her dark hair.

"I thought you'd be happy to see me." she said.

"I'd be happier to see you get an education."

"Oh stop!" Sarah waved a hand at her brother and looked around the apartment. "It really is nice Sam. So where am I staying?"

"In a hotel." he said sternly.

"Sam, come on!"

"You know Sarah, you're twenty. Act like it."

"What do you got shoved up your ass?" she snapped. "I'm sorry Sam that I'm not some genius like you."

"You know what Sar? I think you are. I think you were partying too hard and not studying enough or applying yourself. That's why I'm pissed because I know you're better than that."

"It'll only be a week."

"A week of hell!" Sam exclaimed. Sarah pouted and flopped down onto the couch. She raised an eyebrow as she spied something squished between the cushions. Sam was looking at the clock and his eyes widened as his sister swung a lacy, black bra in front of his eyes.

"Something I should know about?"

"No."

"Fine then I'll just call Mom and tell her that her son likes wearing women's clothing." Sarah said, reaching for the phone. Sam lunged over the couch, pinning his sister to the cushions.

"Give it to me."

"Are you cross-dressing?"

"No."

"Then why the hell do you care?"

"Because you're going to call Mom and spread lies." Sam grabbed Sarah's wrist and tried to pry her fingers open. "Come on Sarah!"

"Let me stay and I won't call Mom."

"No."

"Then I guess, Mom's going to get a little wake-up call." Sarah brought her knee up between Sam's legs. He let out a yell and fell off the couch. Sarah gave a satisfied smirk and grabbed the phone.

"You little bitch." he gasped, curled up in a ball.

"I call Mom. I know you have a girl over here. I can tell. She'll be pissed you didn't tell her you're dating someone."

"You tell Mom and I'll tell her you flunked out of Princeton. She'll be pissed about that."

"Let me stay Sam."

"You can stay till Monday then you have to leave." he muttered, regaining his composure.

"So who is she?"

"Who?"

"Your little friend."

"She's no one."

"Sammy, don't lie to me." Sarah said.

"Stop calling me Sammy." he said. "Her name is Ainsley."

"Ainsley Hayes? That girl who kicked your ass?"

"Yes."

"She kicks your ass so you sleep with her?"

"We do a lot more than sleep together and kick each other's asses."

"I highly doubt it. What the hell do you and Ainsley Hayes have in common?"

"You'd be surprised." she drawled from the doorway. "Thank you for finding my bra. Your brother can get a little wild."

Ainsley plucked her bra from a disgusted Sarah's fingers. She gave Sam a smile and began to walk away.

"Well, for starter's, we never cease to amaze each other." Sam said, eyeing Ainsley down the hallway.
