I appreciate it when people like my characters, but I’m really not comfortable with these kind of questions. Yes, Kasumi has really big boobs, but that’s not what defines her as a character, nor is it something that I feel needs to always be drawn attention to (even though I know people will always be noticing, since it’s hard to not to notice, I guess).
That being said, if you really must know, I guess she’s just indifferent? I know this probably isn’t the kind of response you were hoping for, but I do want to make it perfectly clear that she’s a SFW character.
Here’s a quickie doodle of Kasumi to show there’s no hard feelings. But please, everyone seeing this message, please stop sending me pervy asks about my OC.
