Punished by her brother

Nana squeezed her eyes shut as she continued to hear Bambi being punished by her master, Nana's brother.
Nana knew, that her time too, would come and meet her destiny.
After a while, the squeelings stopped. It was then taken over by pants and groans of ecstasy. She could hear it just in the voices.
Then, she felt her chains being tugged. She knew, before long, she would fall victim of her scandalous, incestorial brother.
"Nana, be a good girl. Come over here. I just want to lock you in this pillory. I promise I won't touch you virginity. Trust me. Your punishment consists of me locking you up in this pillory and..." Nana's brother said. Nana opened her eyes and decided to let everything be decided by Fate.
Silently, Nana's employer locked her up in the pillory (Wherever that could have came from, as there was no pillory earlier on). Nana looked around in her uncomfortable position. She saw Bambi, fully dressed in her maid outfit and with a red face, crying and chained to the wall. She dare not even face Nana.
"And, of course, you need some spanking!" Nana's master said brightly.
"Wait! You told me that you would punish me by locking me in the pillory! You never said anything about a spanking!" Nana cried
"No, I did not. Neither did I complete my sentence!"
----
I am so so embarrassed. Never have I, in my whole life, be so humiliated before.

I raised Nana's black satin skirt, revealing a nice pink lacey panty. Carefully, I raised my hand,
"Oh! I'll do it very lightly, as this is your first punishment. Only 5 from my hand, and 20 from the paddle." I told Nana.
I saw Nana's face nearly breaking out with tears and I told her
"All right. 5 from the paddle. Hey, you know, Bambi was having 300 from the paddle."
I took the paddle from the mantelpiece and whacked her ass 5 times. By the time I am done, Nana had her ass as red as a lobster and she was fully in tears. I left the basement in disgust and left her and Bambi locked in their places and switched off the lights

"Hey Bambi, what did my brother do? Did he fuck you?" I asked, in the darkness.
"No, the Master was punishing me by beating me. Did you not see?" Bambi replied harshly
I was confused. I distinctly heard the ecstatic voices. What is wrong with me?
Oh well, tomorrow is a new day, I hope my brother will release me.
