What would you do if your right hand turned into a cute girl?
kill myself because I know aliens have invaded Earth and will destroy my family.
Love her and care for her. I know how this works and if she's on my hand and the conditions are the same as Midori Days then what I have is the start of a wonderful relationship as long as I can avoid lolis, traps, sisters, scientists, daughters of scientists, girls mistaken for class presidents and gangs.
Why not get migi to suck you off under the guise that you won't be able to protect yourself properly if you are horny. I mean the fucker has a mouth with a tongue and everything.
