My father remarried and my new gyaru sister suddenly started making fun of me for being a virgin from the first time we met. She treated me like I was invisible and showed me her panties in a very defenseless way! Even virgins have human rights and sexual desires...! I mustered up my courage and fucked my sister right away! I made my sister climax many times with all my might! This is the power of a virgin! But even so, my gyaru sister couldn't stop looking down on me, so I came inside her many times!
