I think Jun is a horrible trap.
Why? Because it's just a female voice, face, and body with a penis attached. Real traps have at least some boyish look to them that hints to them being actually male. Look at Mako-chan! You look at him and may think initially, "That's a girl." But then you see the penis and you go, "Oh... well... i can kinda see it now." Jun does no such thing. Now granted, that may sound like a perfect trap. But essentially, all he ends up looking like is a DFC futa. God damn people don't know shit about what it means to be a trap.
