She sneaks into his room, her heart pounding as she watches him sleep, his cock tenting the sheets. Unable to control her urges, she reaches out, gently stroking his length until he stirs, awakened by her touch. Their secret love affair begins, a dance of taboo passion that threatens to consume them both.
