Get naked on all fours, put your favorite dildo on your mouth and go crawling to the bathroom, lift the toilet lid halfway and put your head through the hole.
Stay like that, with the seat around your neck, while you spend the next 5 minutes fucking your asshole, then give your ass 50 slaps on each cheek and 5 more minutes of ass fucking. Finally, stay like that for 3 more minutes and you are done
have fun :P
