Jajaja!
You look extremely pathetic writing with your asshole! But that scrawl cant be called "write". Too bad, pet, you need a lot of training with your ass.
Punch your tied balls 25 times, really hard. Maybe this punishment will teach to you to obbey my orders better.
Ok, take off the marker from your asshole.
Now grab your cock with your dominant hand and start to stroke slowly. Meanwhile, with your other hand, start to caress your asshole.
