The other thing with thighs is gearing. As others have said, it's pretty hard to bulk up just by riding, you'll just tone up your legs (and bum and tum, for that matter too!). However, doing fast short rides with a big gear has potential to add bulk. No fear, 9 miles is plenty long enough and pick a spinny gear and you'll be fine!
