That's quite the angel... I suspect he'll be going to hell eventually, though, he connected much more deeply with the demon, while the angel was mostly just out to have some fun with him. First, though, a lifetime together.
That's an interesting title. Well hey, I'm pretty sure we all do.
Also...Wrapping the dick in an angel's wings was definitely something I actually quite like, so I'm really surprised and happy to see it here.
Great ending though. Well hey, looks like he didn't need to choose one in the end. Truly, Hentai protagonists can never die, especially if dying means having to choose one girl because the correct answer is always...Both of them!
So considering that his will to live = actual increased lifespan = in order to continue having sex (with the both of them)? So I guess that means Hentai Protagonist = immortality.
The moral of this story just might be ... wait for it:
"Cum With Me If You Want To Live."
*beat*
... I'll just let myself out here.
