Please tell me I'm not the only one thinking that having a floating vagina is fucking gross as hell. Not to mention these close-ups remind me of Saya no Uta.
Ok, as someone who had a UI inserted in her womb, I know how Painful having something inserted in your cervix is.
A cervix is a ring of muscle that is walways close, the only time it will open is for child birth. Which is uber painful.
The womb is a very fragile organ, a simple piece of dust is enough to caused huge inflammation.
I wish artist would stop inserting unsanitized and potentially dangerous items in our touhou girls. I hate fixing the mess after wards, the death threat are also petty bad.
