In the dim light of their shared room, Spanish siblings Javi and Maria find themselves alone, their parents away. As they grow restless, their eyes wander, landing on each other's bodies with a newfound intensity. Maria's gaze lingers on Javi's crotch, his bulge evident, while he can't help but stare at her full lips, remembering how they felt wrapped around his cock last night in his wet dream. Their breath hitches as they simultaneously realize the taboo they're dancing with, yet they can't resist the pull.
