Yris has "Additional nipples" 3 of them that are rudimentary. (Which you can with the lab, add one additional nipple for the max of 4 and a days rest instead of using the Maximum option and a few extra days of rest and resources. If you so choose, you can remove all the extras.)
- You'll find Yris in the local bar in Gorn. She will make a bet with you for 200 gold that she can make you cum by whatever means she wants in 5 minutes. Accept, but it'll cost ya. (You'll get a Gallery scene.)
- Now go and get 1 Deterrent potions and another 200 gold, then come back and give it another go. It'll cost you the potion, but at least you'll keep your money this time. (The potion has to be in your backpack inventory.) (You'll get a Gallery scene.)
- For the third attempt you'll need to have unlocked Adya as part of the main quest. (Gorn arc)
- Talk to Adya, then return to Yris with 1000 gold in tow and another deterrent potion. (The potion has to be in your backpack inventory again.) Accept the bet (You'll get a Gallery scene.) then reveal to her that you know everything.
- Finally offer Yris to work for you and you have a new kitty cat to play with.
