Booty Call Rule #1: No lights.

Leaving the lights on forces you to acknowledge who and what you're doing, which can be particularly shameful if your preferred booty call is your sworn rival and it's too mortifying to look them in the eye while naked.

It's shameful if the person moving inside you is someone who, in the outside world, talks down to you and treats you like dirt.

It's shameful if the person riding you is someone you wouldn't want to be seen with in public unless you were in the process of kicking their ass at card games.

Either way, neither person wanted to be aware of their partner's identity while in the process of getting their rocks off.

So when one teen walked into the bedroom where the other was already waiting, it was always their job to turn the lights off. Only then did their clothes come off too.

Kaiba's cellphone vibrated with an incoming call, making it rattle against his metal desk. He picked it up without looking and hit the answer button.

"What is it?"

"I'm waiting for you. When are you coming home?"

Kaiba glanced at his watch.

"Maybe in an hour."

"Fine. I'll wait."

Almost ninety minutes later, Kaiba finally walked into his bedroom in the palatial mansion he called home. There sat Joey on his bed, eyes hollow with weariness, shoes on the floor by the door, jacket draped on the corner arm-chair, lips now parted in anticipation. Kaiba stepped inside, closed the door behind him, and turned off the lights, leaving them in the comforting quietude of darkness.

Kaiba was in the process of undressing as he approached the bed, but before he'd even finished, Joey's hands were on his shoulders, holding him still so the blond could kiss his neck without missing. A sigh escaped Kaiba's lips as he undid his belt and Joey's teeth scraped over his skin.
