Pass out

Alex felt his body getting heavy as the poison sped though his veins, sending fiery jets though his body with each pulse. Darkness crept in as he began to black out, the black haze reducing the world to an image at the end of an ever lengthening tunnel.

Alex hit the floor wondering why the room had suddenly rotated 90 degrees. Then he shut his eyes.

When he began to come to he could remember something about his girlfriend, but it was hazy. He suddenly became aware of a warm wet sucking sensation on his now firm cock. Stacy must have come home, he thought, this feels so good. Then he looked down and his eyes opened wide in horror.

The worm was somehow fusing to him. His erection throbbed, half embedded in the worm. The grey skin of the worm seemed to stretch and suckle pulling the toothy maw forward, down his shaft. The slick slime drooled from the creature dripping down his balls. He screamed, and grabbed at the thing engulfing his member. As he began to squeeze it the pleasure rocketed through his body dropping him to his knees and forcing another jet of slime from the slug's mouth. He braced himself and prepared to make another pull. He took a deep breath as the worm inched further down him nearly at the base. it looked thinner now, more translucent, but closer to flesh. He nearly vomited as he could see part of his body fusing through the worm. The head of his penis was gone the veins fanned out clearly pumping blood through the semi-translucent bulbous worm. His blood. He gripped the creature and he was shocked to feel it as if it was his own skin. Alex pulled, like it was a part of him and the pleasure was like nothing he had felt before.

The sensation tickled him and **** him to shudder, and release the creature. The worm free once more drew its body tight and began to slide further down Alex's rod. The suckling feeling was wild, the creature felt wet, warm, and perfectly tight against him. it seemed to swirl around his nerves like microscopic tongues licking his whole cock. The parasite expanded, slinking further down his dick.

If finally ran out of room and stopped at the base of his shaft, it maw gave a final burst of jelly as it dug into his skin and fused. He was so horny and each sensation along his new member drove him mad with need. He couldn't control himself anymore and his mind began to cry orders to his hands. The creature left him larger than before, at least 8 inches, fading from his matching skin-tone to a translucent grayish green at its tip. The head no longer had its phallic tip, but tapered to a translucent prong where he could see veins and some assortment of strange glands though the murky gel. It oozed a thin coating grey slime along its length, leaving it with a glossy sheen.

He couldn't hold on anymore and began to stroke feverishly, moaning in pleasure. He could feel the pressure moving wildly thought his new member. It made no sound but his body went rigid for a second and then his hips jutted forward in rapid spasms, thrusting his cock into the air By the third convulsion, the excess of sperm gushed from the phallus and coated his flailing hand.

That was amazing, he thought, as his new erection began to fade. The worm began to shrink down and look more human as it did. Without the erection it began to looked human again. Staring in wonderment, Alex said: "Maybe this wont be so bad. I mean, If I go to the hospital they will probably dissect me, right? If I clean up I can just hide it from Stacy."
