"AAARGGGG!" she choked, feeling her climax begin to build. The thundering jerks of ecstasy grew hotter, came quicker, then, exploded with violent release.

The sensation was so all-consuming and so brutal, her head flopped to one side, releasing his spewing cock. She watched it for a couple of seconds, feeling the greasy warmth as it spit on her neck and shoulders before she gobbled it back down. She gave another gurgling moan of pleasure.

"Take it ALL!" he grunted.

Susan sucked and pulled on his dick until she had taken every drop. And even when he was completely dry, she kept at it, working her lips up and down the shaft. When she felt him relax and pull back slightly, she scooped up the stray glob of juice from her tits, her shoulders and neck, and squeezed them between her lips, washing them around his cock.

"Damn, you really like that stuff, don't you?" Mike said as he watched his sister smack like a baby.

"I could drink bottles of it," Susan said, running her tongue over her teeth, pulling the residue of his orgasm into her throat.

She sat back on her haunches and studied him. God, he sure was some little stud. Although only a teenager, he had the body of a man – very muscular and angular. His square-jawed face was almost perfectly handsome, framed by a shock of blue-black curly hair. Another patch of dark hair haloed his prick, with just a hint of hair crawling up along his navel. She placed her hands on his thighs and kissed the tip of his dick.

"You gonna do it again?" Mike asked, swallowing hard. "I… I mean, would you?"
