...am I reading the wrong manga? Did they just coom from having their names said? This is a manga about two misandric sisters falling in love and not about an isekai'd streamer right?
I was gonna originally gonna type this out in the previous chapter but decided not to, my mind changed with her using his hand.
The perverts in this are the worst, in second place are the two sisters.
My first thought was "this guy is now dead and in his last moments, he created a world tailored to his specialty, milking" because there's no way I'm believing that a world was specialized to milking the teets of monsters and he goes there.
The demon king adding the virgin rule is the funniest thing they could've done, and it worked perfectly.
Would have a slightly more logical explanation like a prophecy saying "you will be slain by the purest of heroes".
