Spermsight

Oh my! This may involve masochism or icky bits beyond TH's normal cartoon violence.

Spermsight is a peculiar status condition in which a slut's eyes are outright replaced in their eyesockets by Godsperm of approximately equal size. Each optic nerve is also replaced with the Godsperm's tail, which connects to her brain in its stead. From the outside the slut's eyes may appear to have whited over, glowing with spermatic power or sparking Sperm-Lightning.
  Due to the tremendous power of Godsperm it's a trifling matter for them to function as some of the most intricate and delicate organs in my entire body! A slut's vision invariably improves in this state. Omitting a mortal's need for vision correction is just the beginning. Visual clarity, peripheral vision, color depth, and virtually every aspect of vision is improved to superhuman levels if not already at such a tier. This surely enables a slut to see infrared and ultraviolent light for example, as well as seeing Ghosts. It likely even enables HUD-like effects like a lesser version of the Vizher, possibly including a purely visual version of a Quartarget.
  By the way, it's difficult to overstate how much we fucking LOVE this! Some sluts even "hunt" wild Godsperm for the sole purpose of hoping to replace one or both of her eyes. That's before even considering any of the upgrades—just experiencing Your Godsperm fill out eye sockets is more than worth it. ♥ Spermknights and to a lesser extent spermthralls are particularly likely to wield it. (Even if things go poorly, don't worry, our original eyes regenerate eventually.~)
