TBH, I've seen stuff, and this isn't that bad??? Like bad bad is when you're literally getting cut and bleeding all over, those kind of plays.
I mean, getting torn and the piercing is bad, but not as bad as people are exaggerating it to be. Hitting is normal play in BDSM, and obviously the grape isn't - but that's the plot.
I think it's just common sense to NOT replicate this irl.. if you don't like it, or if this triggers you - don't read it.. bad mouthing it or calling it shit won't do anything..
