"Unggghh!" Hank's eyes widened as he realized he was getting the best blow job he'd ever had. "Ummm, fuck it!" He thrust his hands behind his sister's head, curling his fingers in the raven tresses of her long thick hair. "Suck, suck deeper! Take more of my cock in your mouth!"

Gurgling obscenely, Marie stuffed another two inches of his cock between her wide stretched lips. She nearly choked as the prick knob brushed past her tonsils, but fought back the reflex and flared her nostrils, so she could breathe around the thickness of his prick.

"Jack me off!" Hank moaned. "Jack off my dick at the same time!"

Tightening her fingers around the root of his hard-on, Marie obediently started pumping. Hornily she wiggled her tight ass on the edge of the bed, hopping lightly up and down in a desperate effort to satisfy her creaming pussy. She hoped that her big brother would keep his hard-on when she swallowed his jism. She had to feel his prick fucking into her buttery cunt. "Harder, harder! I'm gonna blow my rocks!"

Now Marie's little hand flew up and down his swollen cock shaft, beating his meat fast and hard. The slurping, smacking sounds of energetic cock sucking filled the bedroom, as her lips and tongue nursed hungrily on his magnificent cock.

His prick started getting longer and fatter, stretching her mouth even wider than before; Marie could tell that her brother was about to pop his nuts. Wanting to help him, wanting to taste his cum, she pushed her free hand between his thighs. Gently she cupped the hairy, wrinkled sac, rolling the twin globes between her fingers.

"Ahhhh, fuck!"
