MIST-141 My Sister Gets Bad Grades Because She's Always Having Sex With Her Boyfriend, And Now She's Mad Because My Parents Are Always Comparing Her Grades To Mine... So She Began To Lure Me To Sexual Temptation So That My Grades Will Go Bad Too

My older sister and younger sister put their stupid things on the shelf and come to interfere with my studies! I thought it was because of my good grades that my parents always scolded me. If it's just a normal nuisance, I'll get rid of it, but I can't easily get rid of him because he's a naughty guy who shows his pants and touches his dick... I'm so excited that I think it's bad because it's incest, and I accept raw insertion...! !
