Imagine Cisco being your first kiss.
You let out a laugh of excitement as the results of the successful experiment came through. Cisco whooped and threw his arms into the air before grabbing your shoulders and kissing you. You let out a squeak of surprise, eyes stretching wide as he pulled away and continued to celebrate.
You couldn't help the grin that curled your lips, "Did you just kiss me?" you asked.
Cisco seemed to calm some, "Yeah, is that okay?"
Your teeth flashed as your smile widened, "Yeah. It's awesome. I guess I'm just not used to it."
Cisco blinked at you, his cheeks flushing ever so slightly pink, "Wait, was that your first kiss?"
You shrugged, "To be completely honest, yes."
Cisco's eyes widened, "So I was your first kiss? My dumb heat-of-the-moment kiss was your first kiss?"
You laughed and nodded.
"I guess I should be glad that you don't have anything to compare it to then."
