Everything was surprisingly perfect. His mind was blank, except for Karkat, and that was fine by Tavros. It made it easier to enjoy this, because it even blacked out the thought that they shouldn't be doing it. He was having his first real kiss! He... could hardly believe it. The butterflies in his stomach swooped and soared, and he felt like he would just fly away into space.

But then Karkat licked him.

All of a sudden he was broken out of his blissful stupor, brought back to reality at the warm wet feeling on his lip. He broke the kiss, pulling back in surprised alarm as his hand went up to his mouth. When he spoke, it was muffled by the hand. "What are you doing?"

Because he had no idea that french kissing was an actual possible thing. Well he did, but not enough to know that was how it started, or anything. So he was pretty darn surprised and clueless.
