She was leaving for college. But her best friend, now roommate, would take care of her for you. You knew what this meant, but you loved her anyway. You only asked if she could keep her laptop open so you could see.
"I just met your girl after work and took her home. She was a little shy and hesitant at first, but I am teaching her how to suck my cock since a few hours. I'll let her go when I'm empty. You should be thankful that someone finally takes care of her."
