Pallington is correct, it seems your game is either not installed correctly or may be interfered with by another mod. You do have to grow additional tits + develop them. The idea behind the quest (to my understanding) is meant as an introduction to nudge you towards the laboratory.

Edit: I didn’t make any changes to the quest reqs beyond allowing it to accept higher sizes, but perhaps in an older strive version the furry settings would disable that. I can’t recall ever seeing that though
