Yes, they are the same person



. The first one is him, younger, at the beginning of his career, while the one below is towards the last era of his porn acting at professional studios (he still has an OF I think and very much full-time Gogo boying nowadays).
His body kept changing throughout his career, was first muscular, then straight fat, then even more muscular, nowadays he's just muscular but.. round. Idk how to describe, lol. He's best when he ditches his mustache, that's certainly a choice.
His best scenes? He has done so many threesome, group sex, gangbang and cum eating scenes especially at KO Studio. His moans have always been erotic and is very much a bottom. Try [ERS96], [ERS102] and [ERS116] at least. The GIF I posted is taken from [OGVY042] from HUNK-Ch.
