Amy combed her long blonde hair, parted it in the middle, and fixed her bangs. Then she slipped into pink panties and bra, her white knee socks, her blue and white saddle shoes and went out of her room, checking before she went to the bathroom to brush her teeth and to make sure Frank was still in bed. His door was closed, so she figured he was still asleep.

She raced to the bathroom and opened the door.

Frank sat on the toilet beating off. "Ah!" Amy gasped. Frank was humped over, his back curled, his hand jerking in a fast pump on his prick. He looked up at the darling girl.

There was no lock on the door. It had been a rule in the house if the bathroom door was closed, someone was in, but Amy had thought Frank was in bed.

"Amy," Frank whispered.

His jack-stroke slowed, but he kept thumping his cock. The stalk was hard, long, and all creamy with cum.

"Ah… gee… ah, Uncle Frank. I'm sorry. I didn't know you were in…" Frank's hot eyes gazed over her lush, young body, her tit-filled bra, her pink patties puffed out at the crotch by her pussy.

Amy backed away. "Don't, leave, Amy!"

"But, Uncle Frank!"

"Stay, please!"

"But, jeez, Uncle Frank… you're… ah… I mean… you're…"

"I know, jerkin' off."

Amy watched his hand action. She trembled. Zings of excitement slithered through her fine body.

"But I better go now."

"I'm jerkin' to you, Amy."

"To me?"

"Yes, thinkin' about you."

"Jeez, gosh, uh…" Frank pounded harder on his cock. "Oooooh, Uncle Frank, golly."

"You look good in those pink panties and bra, Amy."

"Do I?"

"Damn right you do," Frank said, drubbing his cock faster.

"But I better go, shouldn't I?"

"Not if you don't wanna. I'd like you to stay."
