She just wants to watch, for now

"I, I just wanted to watch more of this, erm, goblin culture, for myself," Sister Beverly mumbles. Her eyes are now looking straight down. She can't bring herself to look at the scene in front of her lest she change her mind.

Master shrugs dismissively. "Suit yourself, Sister," he replies as he grips the base of his cock, waving it around for a moment before settling the tip on your waiting tongue.

You eagerly return to servicing Master, paying no heed to your impromptu spectator. As soon as his cock is in your mouth you are already downing it completely, stuffing the last several inches down your throat. You make lewd, exaggerated gags and moans as his tip repeatedly stuffs your airway, forcing you to make quick, rhythmic breaths to keep yourself going. One of your hands wanders from holding you up to down between your legs. You stick an exploratory finger in your pussy and as you expect you are absolutely dripping down there. You rub your wetness across your folds before pulling your hand up again to grasp the base of Master's shaft. You can tell by the way his length is stiffening that his first load is on its way soon.

Master almost immediately begins roaring in a raucous orgasm. He places both hands on the back of your head, holding you in place as he pours rope after rope of hot seed directly into your stomach. You hold yourself there as long as Master needs of you, only letting the final few spurts even hit your tongue. You let these last few drops settle in your mouth for a moment, savoring the taste before swallowing it all down.

You look over to Sister Beverly with a satisfied grin on your face, only to be a bit disappointed to see her covering her face with both hands. She's obviously quite embarrassed to actually be standing here watching this even though it was her idea to be here in the first place.

Master, seeing the nun be so bashful, immediately steps over to her and pulls one hand away from her face. He looks her in the eyes, and says, "Come here, I have an idea. I won't **** you to do anything, I promise."
