"...Sorry," he mumbles, flushing with embarrassment. It's hard to stay embarrassed though with Oikawa's mouth tongue on his cock and balls. His breath hitches when Oikawa's tongue licks there. He should have expected it but it still surprises him, the muscle tightening without is meaning to.

His hand fumbles in finding the lube to hand over to Oikawa before he licks at his cock a bit more. He's still trying to ground himself but he's excited and anxious...so much like the very first time Oikawa finally fucked him.

Why is Oikawa doing this? He has to know Kageyama's never gotten over him, right? So what is this?
