Prompt: Dare
The entire host club gathered at Tamaki's mansion for a sleepover. Haruhi was invited because she was one of the guys. So, when Hikaru suggested that they all change into their PJs together, the "girl" had no objections.
"But wait!" Tamaki exclaimed. "Haruhi's a girl! She can't get changed in front of us!"
"Boy, girl, what's the difference?" Haruhi asserted her strange philosophy.
"Yeah," Kaoru agreed. "Let Haruhi get changed with us." The Hitachiin twins wiggled their eyebrows, which caused Daddy to pout.
Mommy intervened. "Haruhi, go get changed in Tamaki's bathroom." The raven-haired boy pushed his glasses up his nose. They flashed evilly, making his words final.
Clad in rose-patterned pajamas, Tamaki pulled out a standard die. "I'm number one, –"
"Yes, you are," Kyōya purred, affectionately ruffling the blond's hair and nearly causing Haruhi to throw up.
"– Kyōya's number two, Mori's three, Hunny's four, the twins are five, and Haruhi's six."
"Hey!" the Hitachiin brothers protested in unison. "Why do we have to share a number? !"
"Because you're practically the same person," Kyōya replied coolly, with no room for argument.
Tamaki rolled the die. "Two. Kyōya, truth or dare?"
Kyōya's glasses glinted. "Dare."
Tamaki sat and thought. Hikaru leaned in and whispered something in his boss's ear. Tamaki's eyes lit up. "Kyōya, I dare you to marry me!"
Kyōya sighed and pinched the bridge of his nose. "Try again, Tamaki."
"Uh, uh, um, oh! I dare you to… tell your dad that we're together!"
The room was filled with an awkward silence, which Hikaru broke. "Wait – you two are actually going out? !" The twins broke down in hysterical giggles, until Haruhi stopped them with two pointed slaps.
"No, Tamaki, I can't," Kyōya actually pleaded.
"It's my dare and I'm sticking to it." Tamaki passed his boyfriend his cell phone.
An hour later, Kyōya sat on the blond's lap, in tears. "I can't believe he…disowned me!" the usually stoic boy hiccupped.
"It's okay," Tamaki soothed, signaling to the others to leave. Once they were gone, the blond pulled his boyfriend into a deep, passionate kiss. "You can always live with me," he murmured against Kyōya's lips.
Kyōya straightened. "I will become the most successful man on the earth, to prove my father wrong!"
"And I'll become the second most successful man, so I can support you."
Kyōya tried for a grin. "Yeah, right. You couldn't success your way out of a cardboard box!"
"Hey! That sounds like something I would say, except meaner!"
Kyōya laughed and snuggled up in Tamaki's arms. Rather forcefully, actually, as Tamaki had no idea that he was supposed to be hugging the boy. Anyway, they fell asleep in each other's arms, hoping for a bright future ahead.
