Luke remembers the spellbook

A glint in the grass caught Luke's attention. The spell book! Luke vaguely recalled there being a closing spell for the portal. He hoped against hope that it was feasible.

Luke dove down and seized the book. He flipped through the pages like a madman until he found the right passage, the now familiar image of the portal coming into view.

Luke scanned the pages and panicked.

"What is it? What are you looking for?" Danny shouted.

"A closing spell. I thought there was a closing spell!"

There talk was interrupted by a high pitch squeal of pleasure from Becky. Both boys jerked their heads to their defiled friend. She and the monstrosity were still locked in their unnatural coitus, but it was actively getting worse. Becky licked her lips as she rocked back and forth, seeming to savor the infernal boning she was receiving.

Luke realized this scene was something out of a hentai, but this tentacle **** was looking more and more consensual.

"We don't have much time," Danny said, "that thing is doing something really bad to Bex."

"I know. Fuck. I need time. It was here."

Luke turned through pages until he found "closing ritual." He scanned the page.

"Can we do this?" Danny asked.

Luke nodded his head.

"Grab me some earth and a branch. I can do it myself."

With the dirt in his right hand and the branch in his left, Danny started to chant the words: "Portal, Portal, take this dirt and wood. Portal, portal please close for good."

Much like with the opening spell, the closing spell required the words be repeated until the portal closed. As Luke reached his third run-through, Becky suddenly let out a lustful wail that filled the glade.

The pouches of wicked purple fluid swelled and then deflated suddenly. The tentacle shot forward, lodging itself deep in Becky's supple womb.

Luke watched in sickening horror as bulges ran down the length of the tentacle and into Becky's body. Soon, thick purple fluid started to leak from Becky's vagina.

Becky was in rapture. She giggled and cooed as he body took in the demonic cum. Multiple orgasms washed over her in the process.

"Don't stop now," Danny screamed, bringing Luke slamming back to reality.

Luke continued, stumbling over his words at first, but soon reaching the proper rhythm.

The tentacle moved to start thrusting into Becky once again. Now the other tentacles began to descend, seeming intent on getting in on the action.

Luke now shouted the closing spell desperately. He was beginning to feel that all was lost when an invisible power stopped each tentacle in its track. With the next recitation, they hesitantly pulled back ever so slightly.

With each successive iteration, the portal seemed to shrink, inch by inch. The tentacle in Becky's pussy pulled out with a wet pop, causing more corrupt fluid to trickle out of her.

Soon, the tentacles were slamming about wildly, trying desperately to avoid being sucked back into their own world. The original tentacle disappeared last, just as the portal snapped close.

None of them could see that one of the wiggling little cilia from the main tentacle was severed with the closing of the portal, causing it to fall to the ground, seemingly lifeless.

Becky collapsed onto the ground, seemingly ****. The young men rushed to their fallen friend.

Luke wanted to sob as he looked at Becky. She was an utter mess. Her clothes and legs were covered in a mess of dirt and glowing purple fluid.

This was his fault.
