18 [FM] I let my cousin who has never seen a naked girl help me shave my body

He lives with my grandparents who are genuinely nice and wholesome people, but pretty conservative and religious, so he is very sheltered. It’s as bad as my grandma not letting him watch or play Pokemon because apparently that’s worshipping Satan. He’s also not allowed to have a TV or computer in his room and stuff like that.

So this summer break I’ve been sitting him for my grandparents because of private family reasons. That evening he was watching TV in the living room while I was going to groom myself. I went into the shower and forgot to lock the bathroom door. After a while he came in to ask me something, not expecting me to be naked. At first I didn’t notice him, but then I turned towards the door and he was standing there, visibly nervous, but not leaving. I asked him what he wanted and he just asked what I’m doing. I told him I was showering and since I already applied shaving cream to my armpits he asked what was up with that, so I explained to him that girls gotta shave too, just not their face. He said he didn’t know that, so I told him where most girls remove their hair and whatnot.
