That's more or less why Katie, Jenna and Lily are my main girls. All of the girls are gorgeous, since they are obviously designed to be visualy appealing, but in contrast to Zarah, Bella and Debbie who instantly jump onto MC's dick; the first three take a lot of effort to get close to, they don't want MC for casual sex, they want him as a future partner, and that makes them way more attractive.
From those three, to me Katie is the best of them, I love her banter with MC and how tough and fragile she can be, at times she feels more than Jenna. I'm really hating the three amigas plot tho. It looks like it's going to an eventual foursome, which will diminish her supposed "love" for MC, since no woman in her right mind would share her man and risk losing him.
