Oh, I just had one of the best orgasms in my life, all thanks to this series. (To read the whole series, you have to go here.)
There are 10 chapters. I started from number one, pushed myself until I was close to the edge, then I stopped and forced myself to read the next one without touching myself once. The series itself is kind of cliche (semen gives angels power, etc) and the art is a little weird at times, but it has just about everything in it! Some rough sex, some loving sex, a little bit of yuri action, double penetration (once with a double-cock!), tentacles (arguably futanari tentacles), and even incest! So by the time I got to chapter 10, I stuck a little bullet inside and that sent me over the edge!
The only reason it wasn’t the best orgasm of my life is because that darn bullet wasn’t my partner’s penis! /pout
