Continue rubbing herself

Both of Amy's hands were now on her breasts as the warm water ran down her curvy, tanned body. She sighed again and slid down the wall, sitting on the floor of the shower with her legs spread.

One of Amy's hands slid over her stomach and across her thigh. She rubbed her inner thigh with that hand, continuing to fondle her breast with the other hand.

She slowly moved her hand towards her pubic area, rubbing it gently. Amy started to rub her opening, carefully at first, but then increasing the speed. She moaned softly, not even noticing that someone was now watching her with shock.

Cindy was leaning against the door to the shower, staring at Amy intently. She had never been so turned on by a woman before in her life. Cindy found that she was now rubbing her own breasts through her shirt.
