From my parents' house, my aunt Yuka is staying in my room due to work reasons. She's always been beautiful, and secretly I've admired her, but after a long time, her beauty has only become more refined. But above all, I can't help but be fascinated by Aunt Yuka's sexy butt and her transparent panties! Unconsciously, in front of me, she shakes her transparent panty-clad butt, and I'm drawn to it, unable to resist grabbing that plump butt...! This is the record of the five days my aunt and I relentlessly indulged in passion.
