True performance anxiety by the top. He had a fantastic bottom that wanted him badly. Instead, I think the top either prematurely ejaculated or couldn't hold an erection. The bottom is asked if he came and he replies "cum?" as if he's never heard the term. Think the bottom was embarrassed. This is something we all encounter at some point when letting an inexperienced partner share our bodies. I had one noob cum just 10 seconds into my sucking him. Thick, ropy wads of cum that I swallowed. Stayed down on him for 20 minutes afterwards and he was able to get hard again, enough to lose his virginity to me.
