is it possible that he recognized him???

It depends if the uke’s voice is very distinct, it could be possible.

Or uh he got erection when he saw him laughing or something like that? He had similar reaction at first time? I think so...?

It could be, if he got aroused by seeing him then that would give him a very big hint that he’s the bj since he’s sus of him now

lmaoo its getting interesting ig
