He lay fat and thick upon her tongue, and nestled in her warm oral wetness. And why shouldn't it be so? She looked up at his face and saw it in the reflection of her own. The same chestnut hair, the same greenish-blue eyes, the same smooth, well chiseled features. He was, for Christ's sake, her twin brother, and they had been lovers since their teens.

She released him, leaned back, wiping her trembling lips. He was undoing his belt; she could read in his eyes what was on his mind.

"No," Sammi insisted, standing up. "I have to take a shower. The water's running already."

She'd forgotten about the water. Steam was coming out of the top of the shower compartment. Sammi unhooked her garter belt, dropped it, and turned her back to remove her panties. It was a mistake. She was half bent over when she felt the blunt knob of his cock pressing between her legs.

"Stop, Goddamn it!" she shouted, but he was atop her, his upper body lying on hers, keeping her folded over, his hands full of her firm tits, his cock slithering between her legs and penetrating her cunt without any guidance whatever. It knows the way by now, she thought bitterly as he thrust deeply into her cunt. She had to brace herself on the shower door to keep from plopping onto the floor.

"You still love it, Sammy," he was whispering into her ear. "I know I do."

His cock moved rhythmically in her pussy. She'd have sworn, two minutes ago, that she was too dry for penetration, but the squishy sound of his cock fucking her proved her wrong. She was oozing juices from the walls of her cuntal sheath, and his prick bathed itself in the liquid while he explored her sweet, snug depths.

"You're breaking my back," she protested. "At least let me turn off the Goddamn water."

Reluctantly, his cock pulled back, and it emerged from her pussy. She stood up, touching herself, feeling the sticky dew that coated her lips and seeing the sheen off of it on the stiff prong of her brother's cock. But instead of turning off the water, she jumped into the shower, puffing the door closed behind her. He pounded lustily – she could see his distorted image through the frosted glass, and she stuck her tongue out, wiggling it in the air.
