Can we have BALLS as a separate variant? Like the potion says, it only increases the size of the 'third leg'—you'd need a BALLS potion to actually increase the size of the BALLS. Enemy MP-draining skills could also reduce male BALLS size, whereas chastity cages wouldn't shrink them—in fact, it could be the opposite.
Also, could you make different types of chastity cages? And can we still use the weirdly colored penises?
