A reserved and uptight brunette

You and Alice met as classmates, and you were taken with her immediately. She demanded a proper courtship, with dinner dates and formal wear and no sex until you committed, but you didn't mind because was always kind about it. Being very pretty also might have helped. She's about 5'7" and slim, with perky boobs and a small round ass. Her skin is pale and without blemish, and her perfectly maintained brown hair reaches her shoulders when she doesn't have it up in a practical bun. Her face is cute despite having thin lips and a slightly pointed nose, and she knows how to use makeup sparingly and effectively so it doesn't look like she's wearing any at all. She dresses conservatively, although she picks clothes that are stylish enough and don't totally hide her figure.

At first you were impressed at how mature and organized she was - carefully budgeting, getting involved with date plans, and even insisting on paying for her half of meals despite expecting you to otherwise play the gentleman. Unfortunately, she approaches sex like it's a business venture. She's only interested once in a blue moon, insists on keeping the lights off, and tries to get it over with as soon as possible. You've spent the past year trying everything from foreplay to roleplay, but she brushes everything off without a second thought.

Until now.
