In the dimly lit closet, a curious sibling discovers their virgin sibling's hidden desire. As they're about to exit, the curious one can't help but notice the growing bulge in their sibling's pants. Unable to resist, they reach out, gently grasping the hardening cock. Their sibling gasps, but doesn't pull away. The curious one, now emboldened, begins to stroke, feeling the heat and stiffness grow. The virgin sibling's breath hitches, their hips moving slightly, pushing into the touch. The curious one, feeling a sense of power, leans down and takes the cock into their mouth, tasting the pre-cum that's already leaking out. The virgin sibling moans, their body tensing as they try to hold back their climax. But the curious one wants to see them break, to watch them come undone. They continue to suck and stroke, bringing their sibling to the edge and pushing them over, feeling the hot cum shoot into their mouth.
