As the step-brother and stepsister's bodies grind together in the steamy shower, their breaths quicken in anticipation. Their eyes lock, filled with desire and longing. Slowly, the stepbro's hands roam over his sister's slick, soapy skin, tracing every inch of her curves. She moans softly, arching into his touch. His fingers find their way between her legs, teasing and stroking her swollen, sensitive folds. The scent of their arousal mixes into the steam, thick and intoxicating. With a growl, he slides his fingers deeper inside her, hitting her G-spot as she gasps in pleasure. Their hips begin to move in rhythm, lost in the sensual exchange. As they reach the peak of their passion, he pushes deeper inside her, claiming her wet, tight passage as their mutual ecstasy reaches its climax.
