The Lewd SSS-class Hunter Girlfriend Gets Eaten by Others!

Have sex with another man in front of your boyfriend without hesitation. I’ve always been interested in NTR, so I wanted to write something like this, but when I actually wrote it, I wanted to put in a little bit of fantasy or hunter elements rather than simply going to NTR or NTS. Rather than having her girlfriend or wife taken away because the main character is too weak to resist another man, I wanted to portray her as having power, but her sexual orientation is close to NTS, and her girlfriend likes to be humiliated by others. Thank you for your encouragement.
