The Tendrils of Voroth

"Okay, let's see what else..... what's this?" Andy said out loud as he came across the spell called the Tendrils of Vornoth. "Vornoth, a demonic creature from another dimension, feeds off different life-giving secretions, and also energy. Once the spell is cast, it will open a small portal to his dimension, where he will then begin extraction of the gifts offered by the caster of the spell. Though it is said to be very pleasurable, over time the portal will grow bigger, allowing Vornoth more power and control. The caster must speak the words Prope Ostium to end the connections before Vornoth's power grows too much, or some of his effects become permanent."

Andy read the page over and over again as his cock twitched to life in his pants. He was curious, but the warning was a little concerning to him. Almost every spell he read came with similar warnings, and he had already chickened out of trying the "Orgasm Parasite," so he began to ask himself whether or not he was going to try any of these spells or just hide the book away.

"Fuck it, I have to try something," he said before he began to read the incantation. He waited a moment, as nothing seemed to be happening. "Did I say it wrong? Let me check the....... wait, what was that?" He said as he heard a strange noise before noticing a small spark of light rising from between his legs. "Woah, what is that?" He said, seeing what looked like a small floating spark hovering there above him as it started to open, not bigger than the size of a dime. "That's cool, he said sitting up before something started to emerge from the hole.

It looked like a long thing green tentacle as it slithered out of the hole and towards him. It soon started to split down the middle, forming two separate tendrils that seemed to be dripping a small amount of some form of green goo.

"Who makes an offering to Vornoth?" A voice said coming from the hole.

"Um, that would be me, uh, Andy?" He said a little nervous.

The tendrils began to glow, hovering above his waist as he looked down and watched his belt begin to unbuckle on its own before folding off to either side. He felt a chill up his spine as his heart began to race, but there was also this incredible lust as he watched his button pop open and his jeans unzipped, revealing his underwear as he saw his penis getting thicker under the fabric.

His pants suddenly slid down his legs, rather quickly, startling him a bit as the tendrils began to touch his underwear. They were tracing the shape of his hard cock, leaving a thin layer of the goo, staining his undies. He let out a small moan as the sensation felt good on his cock.

"Voroth accepts your offering," the voice said as the tendrils began to glow again, and his underwear tore in half, releasing Andy's cock into the open air.

"Holy shit!"
