Your step-sister is taking a bath, but you decide that you want to talk to her about something really important. You're having a hard time focusing and you can't find any solutions. You sit down with your step-sister and tell her what's going on. She suggests that you try to focus on the little things. How about you try to focus on your step-sister's tight, little asshole and you have to stroke your cock and cum. Your step-sister will know you were focused by how big your load of cum is. Your step-sister really wants to help you focus and thinks this will help you. Focus on this pretty, little hole while you stroke your big dick for me. Soak that hole!
