A wholesome and well written story! I really enjoyed the bite-sized presentation of it, with the text in the center and animated illustrations to anchor it. That setup does a lot to keep readers engaged without feeling overwhelmed! The only potential area of improvement in that regard is maybe a slightly thicker font, though it can be zoomed in the browser.
I really like what you're doing with the limited color palette. In most text adventures this wouldn't be the case, but since every action you take is illustrated, I think that pictures for the sexual encounters may be something that players will expect to see.
There was a bug that showed up in both of the browsers that I tried using. At first I thought that the story choice options just didn't always appear when they should, but later I realized that they were just out of the scroll frame with a small margin on top that could still be clicked. I was still able to play though the story, but I don't know all of the choices that I made.
