The Erogenous Zone not in Challenge

[d8man]

Each Heroine in the Harem has an Erogenous Zone listed as part of their Girl Info (besides breast and pussy which are always a target in the affection level-up challenge), this detail seems to be a missed opportunity e.g. Bunny's Erogenous Zone is her Butt, yet never one of the zones to clicked in the challenges. We do have to click Bunny's ears, which happens to be Estelle's Erogenous Zone, yet this is not a target in any of her challenges. The target area does not have to be tiny to match the body part e.g. can be the head area when targeting Vanessa's Erogenous Zone, Lips.

Although, it can be said that it is just Girl Info and does not play, it does seem like a missed opportunity / "loose end" not to tie the Erogenous Zone as part of the Challenge.
