Jungkook jumps at the sensation of teeth against his skin, however gentle. Not being able to anticipate Yoongi's actions has his blood rushing through his veins; he can practically hear his heartbeat in his ears as he licks his lips, tempted to glance back, but too willful to try. The whole point of this exercise is to let Yoongi dictate every action, and if that means that for now, he won't be able to know what comes next, so be it. The surprise made this moment all the better, Jungkook thinks, his head swimming with the thought that there's no part of him that Yoongi wouldn't touch — be it with his hands, his lips, his tongue. With a soft exhale, Jungkook lets his head hang just slightly, cock growing heavy as his hands tighten further still.

"Yeah," he breathes with a quick nod, ducking his head in embarrassment. Is it normal to like it when someone licks there? (Does it matter whether or not it is?) "It's — I — if you wanted to do that again, I'd be okay with that. It feels nice." Jungkook laughs at his own clumsy words, not wanting to switch the dynamic just yet, but needing some way of giving Yoongi feedback enough to make the next decision. "I'm okay with anything you want, Min-ah."
