This is what I think is going on... he's probably scared you'd get mad, and/or scared you'd request the same thing in return.
That's possible.
"I wasn't expecting that... but damn, that was hot. You taste good too lol. Maybe you should just cum in my mouth from now on." Just laugh it off jokingly but hint that you don't mind swallowing his cum.
Then after a few times tell him, "I heard if you eat pineapples the cum taste better. lol" Then getting him to fuck you would be the next step
