"Not that painful?"
Mitarashi Shisui caught the implication: activating the Cursed Seal would obviously still hurt.
"Using the Cursed Seal to give you Storm Release isn't the ultimate goal, Uncle. This is only to help you adapt to and become familiar with Storm Release chakra, then fuse your own Storm Release. Once you have your own Storm Release, you can remove the Cursed Seal."

Orochimaru explained, indicating that there was no problem.
