"Oh, wow – yeah, Sis!" he moaned.

Bunny drew open the front of her flimsy nightgown and arched her slender back. Her plump tits thrust out, the rosy tips standing like little pink rockets ready to be launched from the areola pads.

Jack hauled back on his cock as if he were cocking a rifle. He stared at his sister's tits past the flaring slab of his smoking-hot knob.

Bunny squirmed a bit closer, bringing her thrusting tits up before his cock. She cupped the firm mounds, lifting and deepening the cleavage.

Holding the heavy globes in her hands, she rubbed the edges of her thumbs against her nipples.

Those buds shot out like bullets and his cockhead loomed like a cannonball.

"Juice me, Jack – hose my tits!" she whined. Her eyes were glazed with lust and she was trembling for the feel of his hot, thick fuck-juice splashing all over her tits and nipples.

Jack aimed his knob at her tits and began to jerk on his stalk vigorously. His piss-hole opened and a glob of gooey pre-spunk oozed out. It spread out on the purple slab like cream on a fat plum.

Bunny's cute little nose twitched as she breathed in the musky aroma of heated cockmeat and the starchy fragrance of his preliminary seepage.

The pungent perfume of his prick was tantalizing the horny nymphette. Her mouth was drooling and her cunt was smoldering. If only he wasn't her brother, she thought.

Some tenacious inhibition told her that she mustn't let things get out of hand, that incest was taboo – but that feeling was fading away in the heat of her desire.

She thought that it wouldn't be too naughty if she were to finish the job for him. A handjob wouldn't be like really committing incest, she reasoned.

She was about to offer to take over.

But then Jack began to shake and tremble.

"Here it comes, Sis…" he gasped.

"Oooooh – cream my tits – slime me, Jack!" she wailed.
