[Sana] Sister on the potty

An older sister with a generous bust and a lace top apologetically offers her younger sister a nap, promising to change her clothes and cuddle together. Later she is shown perched on a potty in a strawberry-patterned top and a ruffled skirt, unable to shift her hips yet finding intense pleasure in peeing while dressed in childlike attire. After washing the sweaty garments, she thanks her sister and urges their brother to return home more often, closing the intimate domestic scene.
