He smiled and gave it a bit of a lick on the tip.
"Ah~!"
"Damn..~"
He locked it again but this time it wasn't by the tip, it was on the side of it.
"Nghh~s-stop teasing..~"
"Sweethearts~..I just wanted to tasteee~"
"Nn..grr..~"
"There goes that cute sound again~~"
"Grrr..~"
He smirked and moved up and got real close to his neck.
"Do it again~.."
He looks at him for a moment, then smirks back
"Grrrr~"
