Tim's finding it a little hard to breathe, but at the same time he's finding that he can't really bring himself to care.
"I love you."
The words hang in the air, an almost-maybe-it-sure-as-hell-seems-like-it tangible thing that Tim wished he could reach out and grab and tuck away in his utility belt and keep it for all eternity because it was the phrase he had been wantingwishingwaiting to hear for the longest time.
Kon is looking more and more nervous by the minute, hands idly picking at his shirt and mouth opening and closing like he wanted to say something else, but couldn't quite seem to piece the words together.
A moment passes, and Kon finally finds his voice.
"Look man, just forget I even said anything. It's okay-"
Tim can't bear to hear anymore, so he surges forward to press a silencing kiss to Kon's lips.
There's a millisecond delay before Kon registers what just happened, a millisecond delay before he is returning the kiss, talented mouth working its magic on Tim's until the shorter male is even more breathless than before. However, Tim manages to find enough air within his lungs to pull away and whisper a hoarse, emotion filled "I love you, too" into the heated air between them.
Kon pauses, lets Tim regulate his breathing for a moment or two (after all, he didn't want him to pass out or anything, even though they have the whole night ahead of them), and then kisses him again.
