After a long and tiring day with her, you two started returning to Xavier's School for Gifted Youngsters (in your car, preferably a sports car and second-hand👍). You two did a lot that drained all your energy, you both couldn't wait to get to your bedrooms and fall on your beds.

You, obviously in the driver's seat, and she in the passenger's seat. While you were driving, she was so tired that she fell asleep and lay her head on your shoulder. You couldn't move her head, though, you were driving, so you let her have her head on your shoulder.
