Siferus clung to the ceiling of the pool area, waiting for a single student to be in there.

He finally got his wish, when Tessa came into the pool area.

Tessa walked at poolside. It was now as she wanted it, silent and solitude. When other students where there there was noise and ruckus, things she didn't care to have when swimming. Now she could swim in calm water by herself without interruption.

She cursed her body once more. Stupid school swimsuit was given her by her height as usual, and it was cramped on bust and hips. Her breasts were practicularily bursting out from neck and sides.

Without giving it further thought Tessa did few stretches and went in pool, starting to swim in slow pace.

Watching the blonde, busty beauty stretch was enough to get him horny. Crawling across the ceiling, he threads the doors closed, preventing anyone getting in or out.

When she reached the side of the pool to get out, he was standing there, smiling at her lustily.

"Well, hello there."

Tessa hanged on the edge of pool, half way climbing up. For a split second she just stared at apparation infront of her. After the moment seeming like forever; her eyes bewildered and she let go of the poolsid, falling back to water along loud shriek.

"KYAAAaaah!"

Reaching into the water, he coiled a tendril around the waist of the beautiful girl, hoisting her out of the water.

"My, my. You're sexy." He taunted, one of his tentacles beginning to rub the crotch of her swimsuit.

Reaching up with two more tendrils, beginning to tease her large breasts through the small bikini top.

"You have beautiful breasts, my dear. I'm going to have a great deal of fun with them."

Tessa screams as the tendril wraps on her, pulling her up without effort. The tendril hitting the crotch sends shivers trough her spine as it graces her most intimate area.

"wh-wh-what are...? oh god!!" She mumbled, clearly panicing.

As the two other appendages reached for the tight chest of swimsuit she whimpered in despair, the two pressing against soft flesh.

(by the way, we are required to wear school swimsuit... so no bikini for you =))

(My mistake. Doesn't matter. It's coming off anyway )

Reaching up, he binds her hands together over her head. Letting go of her waist, that tendril reaches up through her swimsuit, the tendril snaking against her bare skin, tearing her suit off in one motion, wrapping his tendrils around her bare breasts.

With the swimsuit gone, he was free to tease her bare pussy with the tip of his tendril.

"Such a pretty body. You must be new here. Welcome to Shokushu. I'm Siferus, your monster for tonight."

Tessa shrieks as her hands get forced up, leaving her front humiliatingly undefended. The tentacle slithers under her suit, on bare, moist skin. Tessa starts to breath faster, feeling its soft tissue on her.

"Uh!" she gasps, as the quick motion rips the whole suit off at once, nudging her body slightly. Her jugs fall free for only a split second, getting embraced my tentacles.

For her further horror, one more tentacle slides against her now bare slit. Tessa squirms as hard as she can in vain, sobbing.

"t-this cant be real!"

Enjoying her shrieks, he started pressing the tip of his tendril against her folds, spurting an aphrodesiac into her, squeezing her breasts, the tips flicking her nipples roughly.

"I assure you, this is very real."

An evil smile gracing lips, as two tendrils coiled around her legs from ankle to thigh, pulling her legs apart.

Tessa feels her nipples stiffen under teasing, unnerving pleasure hitting with each brush. "p-please stop..." she begs.

Sudden rough pull forces her legs apart, leaving her exposed. She flushes totally red, shrieking desperately: "NOOOooooo!"

Siferus pushed his tendril into her soft passage, her body beginning to get hotter from his aphrodesiac.

He pulled her legs apart the rest of the way, pumping his long, thick tendril in and out of her slit, while two more tentacles groped her round ass.

The two tendrils wrapped around started massaging her heaving mounds, flicking her nipples harder, the tips of the tendrils around her legs caressing her inner thighs.

"Starting to feel good yet...What's your name?"

Tessa shrieks as the appendage plunges in. It felt so rough and yet so oddly good. The thing started to do her good without hesitation. Nudging there and begging and groaning, she could but protest as further tentacles reached for her soft forms.

Next to hazy feeling of getting done without mercy, she heard the thing inquire her name. No way she wanted to give it... wait, she actually did want to tell it... and it didnt even feel wrong to be done like this like it did before.

"T-tessa..." she panted.

Siferus smirked at the girl.

"Tessa, you say? Pretty name."

Sliding another tendril into her sex, pumping them in and out of her relentlessly, wondering how long she could resist his tendrils.

Squeezing her breasts, he stopped flicking her nipples and started rubbing them with his tendril tips.

Maneuvering her body so all she can see is his thick cock, ready to violate her with it.

"You see this? I'm going to make you take this in your pussy and your mouth. You get to pick where I start, cutie."

Tessa was starting to lose it. Not only did it feel good, there was something odd going on, she felt as if drugged. Then she felt the pressure suddenly double. With loud groan Tessa felt how second appendage pushed in her while rest of her body was violated by more of its kin.

Starting to give in, she allowed her eyes to close, only to find herself moved. She opened her eyes to see what was going on. Infront of her was things huge member. Tessa's eyes showed pure terror as she listened the monsters words.

Starting to squirm again Tessa screamed and pleaded for her freedom.

Siferus made it clear that he wasn't letting her go now.

Continuing to pump his tendrils in and out of Tessa with reckless abandon, pushing them in deeper to her hot folds to arouse her more, if he could. Tapping his member against her cheek, anxious for the drug to take hold. Sometimes it took longer than others. This one was worth the wait.

"Does it feel good yet, Tessa? Do those tendrils please your moist hole?" He taunted her, now tapping the long, thick member against her soft warm lips.
