“Hmmmm… Mmmm! Hmmm!” In fact, I didn’t even know what the sporty boy was moaning for, only that the wood between his thighs kept pulsating and precumming.
“Hmmmm… Mmmm!” This frequency means cumming! Stop, then continue, and then again. The sporty boy seems to be at his limit. I asked if he wanted to take a rest, but only heard another “Hm.” I realized that we could continue towards the next limit.
