Carlos, always the curious one, stumbles upon Maria in the bathroom, her lithe body glistening with water, soap suds clinging to her curves. She's oblivious to his presence, her fingers working her clit, lost in her own world. Carlos, frozen, watches as Maria's body responds to her touch, her nipples hardening, her breath coming in short gasps. His cock tents his pants, aching to replace her fingers. When Maria finally notices him, she doesn't stop, instead, she beckons him closer, inviting him to watch, to touch. Carlos, unable to resist, steps forward, his hands reaching out to claim his sister, their bodies entwining in a dance of forbidden lust.
