You keep at it

You would be inclined to try again, but one of the guards steps into your cell, and starts fucking you from the rear. After that, there is someone else who fucks you. And someone else. And someone else. And someone else.

It is only the evening when the number of guards dim down. But by that time you are exhausted, and you have no strength to continue.

At dinner time a dildo is shown into your mouth, and you quickly gulp down its contents. In the following hours you manage to get some sleep, despite the occasional visits by the guards. And somewhere on the line another day starts.
