Cum in my mouth

She does not stop her thrusting long enough for you to speak, so you simply point to your mouth and nod as best you can as you're being stuffed with cock.

"I was hoping you'd want it directly!" The woman cheers.

She keeps going for a bit longer, though she seems to pull her thrusts back so that her cock is grinding more against your tongue and hitting the back of your throat less. You are surprised when she spurts the first shot of cum into your mouth. It is warm and thick, quickly mixing with your saliva as she humps more and more into your mouth. You use all of your willpower to avoid gagging, thankfully her strokes are so shallow now that she is basically not moving; she simply keeps pumping cum into your mouth with your tongue as an aid. After a few more moments she promptly removes her cock and you take a moment to breathe.

"Show it to me, Slave." Your Master is speaking to you.

You wince as you turn to her and open your mouth wide, showing off your shameful state. She inspects your full mouth and contemplates something for a long moment.

"Swallow it." She commands, "Now."

Your stomach drops as you hear the words. This won't be easy. You close your mouth and attempt to swallow, immediately gagging on the thick mouthful. Barely keeping it together, you look up apprehensively, feeling as though you have failed to follow the order. Your master and the woman who just face-raped you are waiting patiently for you to finish. You try a few more times, succeeding in swallowing a small bit each time until it is finally gone. You are thoroughly amazed at your ability to complete such a task.

"Your technique needs work, but I will award you a pass in the hopes that you practice swallowing before the next time we meet."

She nods to the other slave and walks out of your little cell, leaving you with lots to consider.
