He obviously likes cock but not cum. Give it time. But there's no way I could swallow that much, I'd be heaving just like that boy. A little, sure, but mouthfuls, no. Is there a second part with reciprocation? Love to see what that boy's got between his legs.
I agree with all the other comments. Seems like that first squirt came as a surprise. The guy shoulda warned him he was getting real close. And he's HOT too! I dunno if I'd rather he give me a blowie or if I'd wanna pull down his pants and give HIS cock a nice BJ. (And I'd definitely swallow every drop of his cum!)
That first shot probably burned his throat, esp when you're not expecting it. Depends on the shooter. Just mentioning this from a friend who's told me it happens.
