In the cramped closet, Joestar siblings find themselves in a tremorous situation. He's a Joestar, she's a Joestar, and their bodies are a Joestar-sized problem. The brother's "Terremoto" powers aren't the only thing shaking - his sister's "Gluglu" is about to be unleashed. They struggle to maintain their virtue, but the taboo is too alluring. With a mix of fear and desire, they give in, their bodies convulsing as they fuck, their fluids mingling in a Joestar-sized mess.
