Lina changes

Alex felt his alien cock stir as he watched the large worm nuzzle against Lina's mouth while she writhed and tried to turn her head away, out of its reach. It was doggedly attempting to push under the tape muffling her screams and he briefly wondered if he would have to assist the poor thing when it turned upward and began to thin itself out, pushing into her nostril.

Both Alex's and Lina's breathing quickened; his from excitement, hers from terror. Her screams turned to grunts as the worm disappeared inside her. Her grunts became gurgles and Alex saw her throat convulsing. Lina's eyes rolled back in her head as the worm did... whatever it did.

Alex was openly masturbating now, his cock had stretched itself out of his pants and his had had started unconsciously stroking it. "I must be over ten inches long, now," he thought as the grey-green ooze leaking from the tip smeared over his length.

He turned his gaze to the small worms pushing their way out of the tupperware and onto Lina's pussy. Each of them immediately turned inward, seeking to enter the orifice Alex had so recently been inside, himself. His strokes quickened as the worms disappeared into her weeping snatch and he saw her puffy, well-fucked lips begin to spasm. Lina's hips bucked once, twice, three times in **** orgasm.

Her body quieted and became still. Alex stopped rubbing his cock and wondered what had gone wrong. Suddenly, Lina's chin pushed up and the tape peeled away from her face with a slow tearing sound as a completely inhuman tongue extended from her mouth.

Six inches. Eight inches. Twelve inches. It waved and undulated just like the worm that had entered her nose and Alex felt himself quake in a small orgasm as Lina's tongue's tip opened and closed like a second mouth.

She lowered her head and for a moment simply stared at Alex, cock in hand, leaking off-color cum. Her tongue moved left, then right, and a look that could only be described as smoldering came into her eyes as she opened her mouth further and her tongue shot across the distance between then, sucking his cock into her alien length.

"Huh!" Alex's breath came out in a huff as warm wetness embraced his parasitic dick. Lina moaned for the first time since her transformation as muscles in her tongue-tube rippled along his member and tried to coax more cum out. Even as she did this, her hips began bucking and her pussy lips bulged outward, releasing half a dozen tentacles onto the chair.

Alex stood agape in stunned silence as the unnatural thing that used to be Lina used the slimy limbs coming out of her pussy to until herself, stand up, and begin walking over to him. Her tongue retracted into her mouth as she came closer, but her cuntacles stretched out further, playing along his thighs and licking his balls. As she closed with him and drew him into an embrace, her tongue snaking down between their chests, Alex saw her nipples distort and become mouth-like openings just like he had seen on her tongue. As he closed his eyes in his third orgasm in under a minute, he felt her mutated nipples close on his and begin to suck.
