It kills me that NTR is often written to be somewhat poetic and/or profound when it's the dumbest shit ever if you think about it more than two seconds.
"It's called 'Beast's Den' and the final line is how they're like beasts now! Wow...!" Uh-huh. Would be real interesting to see the aftermath of a teacher getting impregnated by a student if the stigma of being found out was so bad a consequence, you didn't tell anybody you were raped in the first place.
Ntr stories always need your disbelief to play a part. Unfortunately this kinda a story is all too real and has real consequences which aren't shown here. Would've been nice to see though.
