My little sister 'Aya' is so cute and fair-skinned that it's overwhelming. She always wears revealing outfits that make me uncomfortable just looking at her. One day, she started wandering around the room in a see-through bunny costume, saying she was going to wear it for a school event! It was such an indecent outfit that as her brother, I tried to scold her harshly. But then she threatened to tell our mother about me peeping on her while she masturbated… and I ended up being cornered by Aya. As soon as she saw my dick, she exclaimed, 'Wow... it's so big?' and suddenly gave me a blowjob! Though I was taken aback, her destructive see-through bunny costume made me give in easily. Slutty cowgirl position, intimate face-to-face seating, intense paizuri blowjob, continuous creampie… total of 7 shots. Completely drained by my little sister Aya's see-through bunny costume who loves me so much, for 130 minutes.
