it seems like we've been neglecting your mouth slut.. a good slut should be an expert at sucking cock..
get out the realistic dildo and give it head.. really put effort into pleasing it pretend your master and all his friends are watching you perform
you do want to please your master don't you? you wouldn't want to fail in front of all of his friends...
after 5min of giving head you can turn the vibe up and edge but the dildo absolutely cannot leave your mouth until after you're done edging!
get right on the edge and hold it for as long as you can and then stop!!
