The doorbell rang, and I opened the door to find Aunt Namikawa Yukari standing there. She was wearing a tight miniskirt, her enormous breasts almost bursting out of her collar, and a mischievous smile on her face. She said she was there to deliver a massage service, but as soon as she entered, I pinned her against the wall, her miniskirt lifted, revealing her already soaking wet vulva. I pulled out my hard penis and thrust it in from behind. She moaned repeatedly, her breasts heaving violently with each thrust, splattering fluids everywhere. I pounded into her vulva, each stroke reaching its deepest point. She climaxed in shame, her expression lost in pleasure. Finally, I ejaculated inside her, and she collapsed to the floor, panting heavily.
