imolestjyanniz on arama translated one of the videos as:
0:01 - Please leave it to me, ok!
0:06 - Do ???? like this. (not sure what she says there)
0:14 - You're so handsome, (literally, "big brother is so handsome!") you make me feel a little shy
0:20 - I'll do my best to provide you good service! ahahaha!
0:26 - If it hurts, definitely let me know
0:35 - It doesn't hurt? ehehe, how is it? I'm good right? Does it feel good?
If you can't bear it, please tell me
0:53 - Yoisho, yoisho (um, just a sound of working hard)
0:57 - Hm? What is it? What would you like me to do for you? If it's you, I'll listen to anything you have to say.
and then lots of echoing of previous lines.
