Because my sister had grown into my ultimate type, I always thought she was cute but serious—someone who'd never be into anything sexual. But I soon realized she actually had an incredibly slutty personality. When she saw me at home with no clothes on and noticed my erection, I thought she'd hate me, but instead, she became aroused and started passionately riding me, grinding her hips wildly. Her lewd behavior was the complete opposite of her usual self, drooling as she begged for my cock with desperate eyes. With erotic hip movements and relentless high-speed cowgirl grinds, she repeatedly forced creampie after creampie inside her. This release features one girl selected from the previously released title "HUNTA-727." Please note that the content overlaps with the original multi-girl release, so those who already own it should take caution.
