When I woke up, it was the same like the usual day, but there’s one thing that is different… The concept of s*x had disappeared from this world. In a world where the concept of s*x has gone, all the women’s view about shame had changed too. If you ask them to get naked, they will show their body to you. They won’t get angry even if you massage their breast, or if you touch their pussy. The protagonist who remembers the only ero knowledge in the world, grab the chance to move on from his dull life by doing ero things with the girls. Training younger sister to become an onahole. Doing ero massage to sports girl. and NTR-ing ikemen’s girlfriend… The protagonist’ ‘all you can do ero’ life…. Begins!!!
