Spanish siblings begin their day with a shared shower, the tension between them palpable as they strip down to nothing. The brother, already aroused, tries to hide his growing erection while his sister, noticing, can't help but feel a stirring in her own loins. They start to lather up, their hands exploring each other's bodies under the guise of helping wash. The sister's touch lingers on her brother's cock, making it twitch, while the brother's hand finds its way to her wet slit. They lock eyes, the unspoken agreement to take things further hanging heavy in the steamy air.
