Derek has been a bit lonely since Eli went off to college so when you come around looking for a place to stay after a fight with your parents, Scott and Alison, he's more than willing to do so. But what happens when he starts to notice how grown up you've become. You've just had your twenty-third birthday only last month so of course you're an adult, but not that you're living with him, he's been noticing how beautiful/handsome you are. What will he do when you come home from a party, shirt in tatters with a large smile on your face and hickeys on your neck? How will he control himself knowing someone else has touched you?
