"Ooooooo, ohhhh, oh, God! Better," Dawn suddenly panted. "Even better than last time, don't you think?"

Steve grunted and thrust his hips upward, stabbing his long pecker up into his sister so far that she squealed with joy and rode him at an even more furious pace. The young boy grabbed the older girl by her spongy, luscious tits and pulled her down onto him by her jugs, his fingers digging into the pliant flesh until Dawn's tits looked ready to pop from the pressure.

"Oh, squeeze them!" the tawny-haired blonde whined in a frenzy of need. "Play with my big tit ties! Feel my nipples, Stevie, lick 'em as you – as you… ohhbhhh, fuck me!"

Sitting on the cold tiles of the bathroom, Lucinda was vaguely aware of something warm touching the insides of her naked thighs as she watched the lewd fucking of her older brother and sister. The little girl was panting, and she noticed, to her shock, that her hands had wandered up onto her tits, and that she was pulling at her tiny nipples just the way Steve was tweaking Dawn's tit-tips.

Lucinda didn't want to look down even for a second to see what the warm sensation along her ass and thighs was, but her curiosity got the better of her at last. Tearing her eyes away from the rutting, moaning couple on the bed, Lucinda looked quickly at the bathroom floor.

A small puddle of slick, hot cunt-juice was forming on the tiles between Lucinda's spread legs! The girl touched it and found the fluid to be very slick and warm between her fingertips as she rubbed them together. It had almost no odor.

Lucinda touched the crotch of her translucent pajama shorts and found them soaking wet. She pried the material out from her sleek belly and saw that her cunt-fur was matted with the hot oily stuff and that her tiny pussy was leaking the warm lubricant freely.

Reluctant to touch the gooey liquid at its source, the little girl made herself do it. Her fingertips grazed the top other shimmering pussy-mouth, inadvertently connecting with the small knob of flesh protruding out of its protective sheath – her… clitoris, if Lucinda remembered her sex education class vocabulary correctly.
