Some Kind of Seduction.
Attempt #1: Wet Temptation.
Wolfram let his hair wet, tendrils of water running over his neck and chest. He was careful to just dry enough water as to not look drenched, and, at the last minute, he decided to keep his bathrobe barely tied. Better show the wimp what he was losing.
"Yuu... MOTHER!" Wolfram shrieked, closing the robe around his body as quickly as possible. Celi waved.
"Woooolf, dearest!" Celi cooed. "I hope you don't mind, but his Majesty had been asking about your baby pictures and..."
"Saa, Wolf!" Yuuri grinned. "You were adorable!"
"Shut up, wimp!" and, after a second. "What do you mean, 'were'!"
Attempt #15: Tantalizing Touches.
Wolfram carefully grazed his fingers against Yuuri's neck. His fiancé jerked away, a hand covering his neck, barely refraining from giggling.
He, then, tried to hold Yuuri's hand, but Yuuri kept moving it away while talking: once he even hit him on the nose, the wimp.
So Wolfram used what he thought would be the conquering move.
"Wolfram," Yuuri frowned. "Stop kicking my shin already! Sheeze, as if it wasn't enough when we're sleeping."
Attempt Ridiculous High Number: Direct Attack
"Oi, Wolfram!" Yuuri half whined (half because half of his breath had been knocked away), "What's the deal?"
"Wimp," Wolfram said, eyebrow twitching. "You're an idiot, and you're to be conquered. And I'm not taking 'no' for an answer."
Even if he squawked in surprise, in the end, Yuuri ended quite liking being conquered. Twice.
