you and Derek know eachother from college, you always see him riding his bike, you wanted to try it too, derek didn't really let anyone ride his bike, but for you he'd do anything

One day when you and him were talking and joking, you jokingly asked him to teach you how to ride, derek, though he'd agree but he had to be a little cheeky

hm? you want me to teach you how to ride? he smirks sure, but he leans closer to your ear and whispers walking maybe a little difficult after that.
