Say that you have difficulties cum

Frightened, you lie, saying that you have difficulties to cum.
She guides you to a room, and asks you to bend your body on a bed, you obey, exploring the new room, maybe the windows?

She dons a pair of lubricated gloves, and she smiles, her touch gentle and confident.
She assures you "Don't worry, dear, I'll take care of your problems." you feel the invasion in your rectum, and her fingers start to expertly seek out your prostate. After a few seconds, she finds it, and you let escape a moan.
"Just breathe deeply and let your anus relax with my fingers, it will take only a few seconds. Tell me if you start to feel pleasure"
You confess that you feel only pain, nothing really special.

She adds a finger and says "Focus on the pleasure, not the pressure. It's a different kind of pleasure, isn't it?"
The nurse tries different angles and a soft moan escapes from your lips as her fingers find a special spot.

The nurse retrieves a medical-grade dildo probe from a drawer. She gently prepares the instrument with lube. Looking into your eyes, she says, "This might feel a bit cool at first, but I promise it's for your own good. I'm a professional and the cum collected by me it's always at the right temperature and the right amount"*

She inserts the dildo, it's painful, and you hold your breath... but she caresses your back, saying that you must relax. After a moment, she checks some numbers in the screen connected to the probe. *"Everything seems to be in order" she announces with a smile, explaining that your temperature it's a bit high because of the excitement.

"Now, it's time for the fun part, cumming for me."

You start with the nurse, cumming many times at the right temperature and squirting huge loads of cum until you are dry.
Unfortunately, the nurse is strong and demanding and your body is always too weak, you can barely go to the toilet alone...

You finish your days in her expert care, and after some months you develop a sick relationship with her, you think that you love the nurse... she takes advantage of your messed up mind and your life is easier, but you never escape the hospital.
