Zaika Inflation

---

If Steele has the Zaika Inflation perk, topmost row breast size increases in relation to their current Lust. The size increase resets to 1 after the player has an orgasm, as long as they have at least one penis or tailcock.

• Explanation from Adjatha in discord for why only the top most row:

  "Yeah, that's intentional. Zaika inflation is limited to your top two tits like the natives. The zaika who have more than the normal configuration are called "Hydras" and their libidos are always at 11 due to the excess. If zaika inflation affected all of a player's tits, that'd mean that Twilit had turned them into a Hydra, and it'd probably be a bad end due to your inability to have meaningful interactions with other people beyond just jumping their bones."

  Most likely due to technical limitations, there are no effects if the player has more than two breasts per row.
