Be the martyr that is thrust upon her darkest desires

I took the contraption in my hands, fondling it nervously, asking myself if it would be enough to quench the fires within me. I knelt, ashamed, in front of Sister Helen, offering the device so that she could use it and my body to her heart's desire.

Helen: Well well well, Sister Layla... Are these impure desires you are obviously having the reason for failing to fulfill the punishment Mother Superior imposed on you? I pity you, you dreadful creature. You have been corrupted by your baser instincts, and you are incapable of honoring the robes you are wearing. Despicable. I'm going to fuck you until you repent.

She grinned at this last part while putting the fake cock around her waist and before my face, thrusting to let me know what was expected of me. Fearing having the plastic member inside me without lubrication, I started sucking with abandon.

Layla: I can't take it anymore, Sister Helen. Please, I need it inside me! My virginity belongs to God, but that doesn't stop you from my giving me my punishment through the back door, right?

I said as I separated my ass cheeks, giving Helen a perfect view of my virginal asshole. I was going crazy feeling the way Helen was making my ass gape, penetrating me with the whole length of the strapon. I had never felt my pussy so wet or warm; I never wanted her to stop, and any moment I would surely cum just from having my ass abused.

I was drunk on the pleasure of pleasing Sister Helen, being able to douse her flames with my dirty holes made me useful, even loved. I came hard, my whole body convulsing on Helen's strapon, my juices dripping onto the floor. I'd never seen her smile as much as when she made me cum by popping my anal virginity. We collapsed on to the cot together, hugging each other tightly, exhausted but feeling more alive than ever.

After resting naked side by side for a long while we both decided to get dressed and leave the tiny room at different times so as not to arouse suspicion. We eventually returned to the common area, where some of the sisters were sewing, others were washing, and others were speaking worriedly in hushed tones. Sister Helen, who looked a little embarrassed and uncomfortable by what had transpired between us, soon put some distance between us by going over to help some sisters with some maintenance work on the other side of the room.
