Hank just stood there, gaping at his sister as she shamelessly pistoned her fingers in her clinging, juicing slit. "Jesus, Sis! You're fucking crazy! I'm your Goddamn brother!"

Marie glanced down his body, giggling at the swollen lump protruding through his jeans.

"I don't care if I'm crazy, not when you've got a big boner like that! Ummm, it looks so big and fat! Take it out for me, Hank! Awww, I wanna see your big dick!"

Hank stepped closer in spite of himself, seemingly hypnotized by the sight and smell of his sister's teenage cunt. Suddenly Marie sat up on the edge of the bed facing him, swinging her slim legs over the mattress. Her, brother did nothing to stop her as she pawed the bulging crotch of his slacks.

"Well, if you won't take it out for me, I guess I'll have to do it myself!"

Hank shook all over as he watched his horny baby sister swiftly undo his belt buckle and unzip his jeans. Hurriedly she pulled down his pants and shorts, releasing his cock from confinement.

"Oh, Hank!"

His cock was enormous, a meaty battering ram of flesh rising straight out of his prick fur and the hairy sac of his balls. It was the first cock little Marie had ever seen in the flesh, and his prick was just the long, fat, throbbing whopper she'd hoped for.

His huge prick pulsed before her eyes, jerking obscenely up and down with its engorgement of cum and blood. The cock knob was puffy and rose in color, and sticky, clear fluid dripped from the piss slit. Her brother didn't want to admit it, but the sight of her wet pussy had really turned him on.

"Oh, Hank, you've got such a big fucking hard-on!" Marie slid her hand up his thighs, brushing his balls as she wrapped her fingers securely around the root of his prick. "It's so fucking beautiful! Ummm, please let me suck it for you! I want to suck the cum out of your big fucking dick!"
