Keep yourself awake

Trying to justify your strong desire to painfully fuck your ass, you tell yourself that you don't want to be asleep in case someone tries to check on you before you are sobered up. At least if you are awake you can try to delay them from coming in your room or figure something out. You look around for the largest thing you can fit in your ass. The dildo your mom got for you to practice anal seems quite small and boring right now. You find a hairbrush with a ridged handle, which seems like it would be fun, though sadly is just as small as the dildo. You think about trying to fist yourself, the idea of which excites you. You also think about impaling your anus on one of your large bedposts.
