This is a 同一cp work based on another author's work. Please read my rambling introduction to understand the nuance of this work!
It has titfighting, nipple fighting, assfighting, catfighting, body modification, and lots of mutual attacking, whilst also including some back and forth. As well as it being my first translation effort, this was my first attempt at writing in first-person.
Please let me know if it worked for you, I hope it did, since the source material was such high quality (Again, please read the introduction, lol!)
