My sister was sitting in the dining room with her legs spread apart. Everything looked normal on the surface, but under the table, you could see a vibrating dildo deeply inserted into her pussy without any underwear on. Clear, sticky fluids were already seeping out, connecting the dildo to her vulva. Her upper body was dressed in proper school uniform, but her lower body was completely naked. The shot should zoom out so we can see her whole body and the person sitting next to her.
