In the steamed-up shower, the two women's bodies press together, their hands roaming in sudsy exploration. The girlfriend's breath hitches as her lover's fingers find her clit, her own hands gripping the sister's ass, pulling her closer. They kiss, tongues entwined, as the water pounds against their bodies, their moans echoing off the tiles. The sister's fingers slip inside her girlfriend, fucking her slowly, building to a climax that leaves them breathless and quivering.
