Just the idea of it, just those words, leave Yoongi aching, desire pulling tight in his abdomen and down his spine. He's not sure he's thinking clearly at all, just letting how much he wants this guide him through figuring it out.

Easing up onto his knees, he straddles Jungkook's chest and reaches down to run a hand through his hair. Not that long ago, it had never even occurred to him that tying Jungkook up was a thing he might want to do. Now he kneels over him, taking in the sight of Jungkook under him, vulnerable and dazed and so eager, tugging thoughtlessly at his bonds, and he knows they'll be doing this again. "Still okay?" he asks, brushing his fingertips against Jungkook's wrist. Already there's a little red around the edges where his writhing has the tie chafing against his skin, but it doesn't look bad yet, not enough for them to stop, not if they don't want to.

"If it gets to be too much," he adds, then pauses, unsure how to continue. It's not like Jungkook's going to be able to talk with a mouth full of cock, but they need some kind of signal so he doesn't overwhelm him beyond what he can handle. "Tug on the ties three times, okay? Quickly, like knocking. And I'll stop." He wraps his hand around himself again, the other clinging to the headboard, as he leans forward to brush the head against Jungkook's lips, a groan slipping from his lips at the sensation.
