Dawn moaned and let herself slide all the way down until her little brother's prick was jammed tightly up in her pussy. The radiant eighteen-year-old whinnied like a mare in heat just pierced by a stallion and began to jerk her curvy hips up and back over his penetrating cock.

Lucinda felt a rush of heat envelope her. Heat as intense as if an oven door had been abruptly opened and she had been thrown inside. Strange fluid was suddenly seeping out of her tiny cunt-hole, and her tits felt hot and itchy. Her nipples stood out against the fabric of her light nightie, throbbing with the need to be caressed.

The inexperienced little girl knew she should tear herself away from the keyhole and go get their father. At the very least, she knew she should go back to her room and leave her brother and sister to their fucking.

And yet she knew she wouldn't. The hot, pounding need in the young girl's loins, the pumping, aching insistence jetting through her nubile tits told her she couldn't.

Lucinda leaned closer to the keyhole, hoping to see it all.

CHAPTER TWO

Dawn leaned forward and placed her palms on her younger brother's shoulders. She steadied herself, then closed her eyes and really started to whip her pussy up and down over Steve's hard shaft. His crimson cock appeared and then disappeared up into her cunt-lips at an ever quickening tempo that soon had the boy growling and wiggling with lust beneath his sister's violent, greedy fucking.

"Unnnng! Jesus, Jesus, God, Dawn! Ball me! Fuck me hard and fast, like last time," Steve blurted mindlessly, obviously lost in the sensuous delight of his big sister's tremendous lust for his prick.

They bouncing blonde groaned and fucked him even harder. Dawn was plunging and heaving, her magnificent body shining with a light sheen of sweat, her head thrown back, her big tits jiggling wildly.
