It'd be easier to stop, Xiao Zhan thinks, if it wasn't such great sex.

Yibo opens his mouth and says, "I want to learn," barreling past the rapid rise of Xiao Zhan's eyebrows. "To last longer. Will you teach me?"

It's their last day of filming in Hengdian when the secret comes out.

Xiao Zhan hears about it from Yu Bin, which probably should've been the first warning sign.

Xiao Zhan looks up, ears twitching. Yibo's staring straight at him, mouth hanging slightly open, a towel clutched around his waist. Oh, shit, Xiao Zhan thinks, blinking slowly once, twice, and then hops right back out the window again.

"You're sure this is okay?" Yibo mumbles now, curling his knees beneath his chin on the toilet seat. "You don't have to check in with me every time," Xiao Zhan says, sounding warm over the fuzzy connection. His face is clear and his eyes are bright. Yibo feels himself relaxing. "Just tell me all about it later, yeah?"

"You can't be serious," Xiao Zhan says. "Zhan-ge," Yibo cajoles, brandishing his PS4 controller and patting the couch next to him. "Just give me like, two minutes. I promise. I swear. I just gotta be online for this drop."

Xiao Zhan isn't sure when a normal evening drinking with his cast mates turned into watching porn with them, but the transition must have been both swift and head-spinning, and if pressed, he'd blame it on Yu Bin.

Two things happen simultaneously when their hands touch: first, the migraine that Xiao Zhan's been fighting all day dissipates so immediately that a loud gasp slips out of his mouth. Second, a torrential outpouring of warmth shoots up Xiao Zhan's arm so quickly that he almost loses his balance and falls off the bench. The next moment, Xiao Zhan drops Yibo's hand. He tries to convert the abrupt movement into something more graceful, but he doesn't think he succeeds. Yibo's eyes have gone wide. His neck bobs as he swallows. What the hell, Xiao Zhan thinks faintly, astonishment thick in his throat. He just manages to keep himself from passing out as the migraine lances through his head again with a vengeance.
