So this manga was about a high schooler who decided to try out anal masturbation because he was bored and he discovered he liked it and had a bunch of toys, but he claimed to be straight. Then his younger brother's friend sleeps over at their house and the uke jumps him because he has a big dick. I can't find. :(
