Going Up Part 2

Taking his rigid erection in his fist, Charlie pointed the massive organ into the deep cleavage of Siren's arched buttocks, guiding his member toward its dimpled target. As his rubbery glans pressed against her asshole, his cock met the stout resistance of her sphincter. His progress was halted, almost at the moment he'd begun, his prick bunching back against itself. He gripped his penis closer to its tip, and resolutely pressed forward with his hips, driving an inch or two of his dick through her anus.

Siren lowered her head, gasping as she felt the thick, hard column force its way past the portal to her bowels. She held her breath, waiting, and Charlie, his other hand spread flat upon the small of her back, both to steady himself and to keep her still, fed inch after inch of his long, rigid cock into her ass, filling her with the organ's thick shaft. Her head dropped lower, her shoulders sagging, and she released her pent-up breath in a long sigh that ended in a low moan, whether of discomfort or arousal-or both-Charlie could not say.

The sound, however, excited him further, and he nudged his thighs forward, planting his cock to the very hilt inside her, his pubes rasping against her impaled buttocks as his groin and upper legs ground against her bottom, flattening her full cheeks between their coupled bodies. Looking down at his hips, pressed firmly into her compressed buttocks, it seemed impossible that an erection as massive as his could penetrate such a tiny opening as her anus, lubricated or not, but, of course, it had accomplished just such a marvelous feat, for the thick, hard organ was buried inside her ass, all the way to his balls.

Again, a low moan escaped Siren, and she rested the side of her face upon her right forearm. Her eyes were closed. Her lips were slightly parted, and she bit gently at the tip of her protruding tongue. Her brow was knitted. She seemed troubled, Charlie thought, but, perhaps, she was merely concentrating.

Crammed with cock, Siren's wide-spread anus fluttered frantically about the massive member that had invaded her rectum, as if in a valiant, but vain, effort to dislodge the trespassing organ.
