Why am I having sex with the capture character after being reincarnated as a mob (maid)?

Anne, a girl who was reincarnated into the world of a girl's game borrowed from a friend.
However, she was not reincarnated as the main character, but as a maid who serves the characters Cecil and Alto.
At first, Anne was unable to recover from her old world, but she decided to live a new life in this world, and was living a fulfilling life despite being a mob character.

However, she had a flaw for some reason. She was unable to use magic in a world where magic can be used. Due to this flaw, Anne was in danger of being expelled from the magic school she had worked hard to enter.

"Maybe Anne doesn't have enough magical power, that's why she can't use magic." "If we transfer our magical power to Anne, she might be able to use magic."

At first, Anne was reluctant to accept Cecil and Alto's offer, but she decided to accept their kindness.
However, they did not tell Anne that the transfer of magical power involves the transfer of bodily fluids, which means that "sexual intercourse" is involved.

Anne felt joy as she was able to use magic every day, even though she might be being violated.
However, things start to get a little strange with her body...

Will Anne be able to pass the test to avoid expulsion?
