Idk which one of these was the main work and which one was the sequel, but in both of them the uke genuinely loves the guys that bang him, and they all love him back.
The uke is a bit apprehensive in the initial work, but he doesn’t actually protest against what’s happening at any point and even ends up encouraging them iirc.
It’s teacher student though, in case that’s a turn off for anyone reading this.
Okay, I hope to God that no one in my private life finds out I asked this.
But is there any yaoi manga where the gangbanging is completely consensual for all parties? As in, the uke is a willing participant and enjoys everything that is happening?
