There are people who can actually do that, my sister is one of them and has no gag-reflex. It's not for sucking dick, it's for inhaling food real quick.
You know, considering how un-dense and straightforward our protagonist is, I bet at this point the only reason she hasn't just confessed and tried to get this farce over with on her end is she's not entirely sure if Mako will just go into hardcore denial or not.
She may be un-dense and straightforward, but she doesn't even recognize her own feelings for her friend. She's too focused on her friend and not herself. Useless lesbians really be taking over society at this point
@Givemeanaccount Imagine more on a bed with your face in the pillow as you think about them smiling and you just feel so happy you scream into said pillow. But basically, yes.
For some people caressing the cheek seems like you're petting them. I can confirm this by the way as I do this but without the kissing of the hand, just some good ol' petting. (No pet-play)
