You can't

You instinctively try to pull away from Therion, but they drag you into the room and sit down, forcing you between their legs.

"This would work better if you did what you were told, but I can make it work."

Therion {if Gagged = true} pulls the gag from your mouth and {endif} holds your jaw open to ram their cock down your throat. They hold it there, cutting of your air, until your throat starts to spasm... and then keep holding it there. Only when you start to feel dizzy do they pull back and let you breathe. You inadvertently moan around their cock.

"Oh, that feels amazing! Do that again."

You don't take orders from Therion, but that doesn't seem to matter; they find way to make you moan. Or actually, scream. The louder the noise, the better it seems to feel on their cock, so they squeeze and slap and pinch at your breasts until your screaming and crying both, and enjoy the vibration and spasms immensely.

After an eternity, they come. But it's not over for you.

"Stay here." Therion pushes you to the floor and holds you down with one foot on your back. "When this dick recovers, you're doing that again. And you've gotten me all riled up, so I don't think it'll be that long."

It wasn't. Soon you're on the cock again, being **** to scream and cry and thrash. And then on the floor, and then on the cock again.

Throughout that long day, Therion learns a lot of things about forcing their own pleasure out of your struggling mouth. None of those things are fun or comfortable for you. Finally, an alarm goes off.

"Oh, look at that, Dreg. It's bed time. Let's get you some sleep, eh? I want you to be nice and refreshed to continue your duties tomorrow."
