On Terri's first visit, when you tell her what men like, choose 'big boobs' (or whatever the text is). Build up all her stats, every visit talk to her about everything but stop before trying to talk her into being a lesbian. Train her in new sexual positions every time, no hypnosis, and then complete her training and ask her to come over. Every visit, choose "talk to her" or whatever it says, then mention the boob job. There are I think four or five variations on the conversation for subsequent visits (which you can do in one visit, just choose the line again and again [there's a glitch where it allows for follow on conversations without her leaving, so you can knock that out in just a few mouse clicks]), then advance a week and the next time she comes back she has BEWBS. Suggest you have sex (which is actually kind funny dialogue, so I won't post it), and then on subsequent visits, you can not only have ongoing sexy boom boom with her, she pays you for ongoing training. You'll have dialogue options each time to progress her further (self-explanatory) down that path (which I think is more Bimbo than Doll).
