Now that your ass is warmed up, get whatever toy you have to fuck your ass (if nothing else use your fingers).
Now lube it up with your mouth. That's it. Bet you like sucking cock? No? Too bad. Only good sluts get pussy.
Is it nice and wet now? Good, start fucking your ass. No other lube. If you didn't get it wet enough keep trying. Good subs get lube, love and attention. Bad subs get pain, anger, and chores.
Is that the hardest you can fuck yourself? Fuck your ass hard. Come on!
