>>65081305My brother and I are only a year apart, and we hit puberty around the same time. When I first discovered porn and jerking off, I showed it to him on our PC and explained everything. We used to read doujins and watch hentai, porn etc., sometimes to jerk off and sometimes to just watch. One day our mom almost caught us mutual masturbating and I think that's when we stopped doing it together. It's weird now that I think about it, but back then it felt totally normal.
