He finds a surprise

Lewis waved his drink at the girls, and they smiled back at him. Kathy and Amber looked a little disappointed that he didn't stay. Niko was bubbly as usual. He headed upstairs toward the bathroom out of need. As he approached, he was about to rap on the door, when he heard a deep sexy moan come from inside. Then he heard something that caught his ear, a female voice whispered, "Fuck me, Lewis." He waited silently outside until he heard whoever was inside groan louder and breathe heavily. It sounded like she was having an orgasm. He continued to wait, listening to the toilet flush and the water run.

Suddenly, the door opened and Ruth, Jake's sister, came out and bumped into Lewis. She seemed to be rather tipsy, weaving a bit.

Ruth was a very pretty high school girl with luxurious shoulder-length brown hair and a dark Mediterranean complexion, like her brother. She was wearing black walking shorts and a white scoop-necked shirt, which showed off her smooth, dark legs and her great cleavage. He could see that her nipples were poking out the material. Her big dark eyes looked at him a little startled, her full lips parted as she said, "Oh!" His hands came up and held her arms automatically to keep her from falling. Her hands rested on his chest from the impact.

They both separated slightly, and Ruth, getting over her embarrassment, smiled up at him, still red from blushing, not knowing if he caught her masturbating. "Hi, Lewis. Fancy running into you here." Kind of dumb, but she's flustered.

"Hey, Ruth. Great to see you." He grinned at her. He always had a thing for Ruth, but had never done anything about it, since she was his best friend's sister. There's just something about her that got his engine running into the red. Even now with the shock of listening to her say his name while jilling herself, surges of blood rushed to his penis.
