i decided to teach my little sister who doesn’t like swimming lessons how to swim. i can’t teach it well because i can’t stand the bulge of my growing chest and get an erection! then my sister who noticed me who was in a hurry with an erection said, “tell me quickly, how can i get rid of it?” i can’t stand it and want you to let me go, but my sister who pulls, “as expected, it’s …”. i was in despair that this would be the end of the brother-sister relationship, but my sister who saw me for the first time in disappointment and suggested, “if you just rub it…”.
