"More… more! Touch me more, daddy! " "Ehhh?!?!?" Yu's eyes popped out of its sockets when Shang addressed Su Yang as her 'daddy'. Even Su Yang couldn't help but raise an eyebrow. The last time someone called him 'daddy', he was nearly kidnapped and imprisoned to be a *** slave for the girl. Yu continued watching her senior apprentice-sister Shang scream in pleasure, her body trembling at every moan, and the image of her senior apprentice-sister Shang – whom she held with high regard and respected greatly – would only slowly shatter in her mind the longer she watched.

"I want to switch places…" she sighed some moments later.
Don't worry you don't have to rethink anything, you are just writing a perfectly normal book for people to read and enjoy (and you're doing quite a good job at it). Although there may be some content in this book/novel that some people may not enjoy that is normal too because never will there be a book which everyone enjoys. Oh and this type of content in books is not uncommon so it's not like you're weird.
