What's with all you self inserting fags hating on NTR?
Vanilla sex with a cuck watching just adds like 30 different levels of fetishism you can get off to.
Too bad it doesn't happen much. It always seems to happen in regular manga though, where the dude sees his crush banging her vastly superior and hotter boyfriend.
Do you really have to be a self-inserting type to not like the concept of NTR?
People making no distinction between self-inserting and empathy. Obviously people do self-insert to get off to this sort of thing. The problem is empathizing so it's better to distance yourself and view the events as pure spectacle.
