Run into the unknown corridors

Unfortunately, it's a dead end, a corridor with a closet full of towels and soap.
You are easily captured and you are tied up, **** to use a harness and the nun says that you must be punished.

The nun strictly holds a small wooden pointer as she encourages you through your punishment session.
She secures a brutal dildo under your ass, and forces you to squat over it. You try to beg her, and you struggle, but when she hits you with her pointer, you think that you are going to die... the world shifts around you and the excruciating pain makes you **** and have a terrible gag reflex.

You quickly understand that you don't have any other option, you will not survive another hit...
You feel the lubed head of the dildo pressing your ass, and she encourages you to impale your ass.
"Move your ass, just the tip, or you will feel real pain" she says holding her pointer.
You feel the thick dildo pressing and entering your ass, the pain is terrible and you clench your teeth, but it's better to avoid her pointer...
"Deeper..." she says with an imperative tone, and you obey... you feel the dildo sliding into your rectum, you are sweating, and you finish one squat.
"Come on, just five more squats!" she laughs "You can’t give up now, not when you’ve come this far!"
Five more?? she's crazy... your body can't take it.

She insists, and despite the burning in your legs and your ass tearing apart, her strict instructions and her pointer convinces you.
Each count she shouts feels like a nightmare of pain and humiliation. "Two! Three! Don’t make me start again! two more left!" she commands, making you moan in pain as you keep impaling yourself with the dildo.
"See?" she says with a smile, "you finish! Good girl!"

She lets you rest and gives you water caressing your face, and explaining that she doesn't want to use the pointer and she will never use it with you again, but you must help her and obey.

When you think that it's all done, she says "Come on, let's start with the next training, we will work in the depth, hitting the floor with your buttcheeks... and also in the speed, soon you can reach 100 insertions fast like a little lusty rabbit, and believe me, your pussy will be wet like a swamp"

You start to cry, but the kisses you on the forehead and encourages you to start.
After many years, you become a docile and obedient ****, your ass is dilated and loose like a huge vagina, and after years of ****, training, and her encouragement, you developed a strange relationship... your mind is messed up, and you start to love her.
One day you declare her your feelings, and she kisses you in return, saying that this will be your little secret. Your life is not so bad after that, she lets you rest during the weekends and you pray and sleep together.

You never returned to your world, but you find a pure and strange love in the upside down.
