Siferus cotinued to ram his giant cock deep into her hungry cunt, his pelvis smacking her clit when he thrusts in and the tentacle smacking it when he withdraws, providing a constant stream of pleasure to her. The tentacle pushed a little deeper into her mouth, it's tip near the back of her throat.

Such a quality catch. I'll have to take you more often. He said, talking loud enough for the deviant promise to be heard.

No! I don't want you to trap me again!,Pia's mind protested.
Even if it feels so goood...

She made small noises of panic, muffled by the tentacle in her mouth. It was far in now, so far in that she feared it would choke her should it proceed further. Fear gripped her, fear strong enough to briefly override her lust. Once again she grabbed at the tentacle in her mouth, hoping to tear it out.

Seeing her go into a frenzy trying to pull his tentacle out told him that he needed to pull it back a little. He pulled it back until she stopped trying to pull and yank.

Don't you worry. You're safe in my care, Pia. He said, never breaking his rhythm, continuing to pleasure his catch, despite that small error in judgment.

Pia struggled with the tentacle a little more. She felt she needed to protest this somehow, while she was still able to think clearly. But the tentacle was slick with spittle and cum, or maybe that was her hand, and she found it hard to get a grip. Especially since the beast taking her, making her his toy was so damnable good at what it was doing.

She let go of the tentacle and surrendered to the pleasure.

A smile rose on the face of the spider as she slowly surrendered herself again. The thrusts into her hungry cunt got faster and harder, no doubt causing a small degree of pain in her as the salty taste of precum attacked her tastebuds.

Here comes more cum just for you, little Pia. He said, moments before the tentacle sprayed hot fluids into her mouth and down her throat.

Pia's mouth filled with semen. She swallowed as much as she could to avoid getting it stuck in her throath, and even suckled the tentacle for more of the salty liquid. A bit of the liquid escaped her lips making her chin glisten.

Yeah! Surrender! Thats how to survive this!
By focusing on her lust, greedily accepting every iota of pleasure, Pia could overide the shame and the pain. This was an almost subconcious reaction from her, awakened by earlier attacks and honed by the aphrodisiacs.

Even so, she involuntarily grunted each time the monster slammed into her. The member was so large compared to her pussy, even more so as the tentacle in her ass made everything so much tighter.

Siferus payed close attention as she surrendered completely again, making a note in his mind not to upset her again. His cock began to bulge as it slammed into her hungry cunt time and again before erupting, seed flowing deep into her tight pussy, while the tentacle in her ass followed suit, both of her lower holes filled with the monsters cum.

Oh god! He is cumming inside me! I am being filled!

Pia felt her cunt being filled with semen, she could feel how each jet of pearly liquid splashed against her inner walls. Each droplet added to her own juicy moistness. There was something indescribable about the feeling, something primal and undeniable, some sort of confirmation about the rawness of desire, even unwanted desire. Pia could not quite put it into words, nor did she try, but it triggered something inside her.
Something that pushed her rapidly towards a new peak of ecstasy.

Had she been able to speak, she would have groaned, or maybe even screamed her lust. As it was, she could only relish in feeling how every orifice was filled, in the wet sounds of each penetration. The thrusting movements caused drops of cum to escape her openings, making moist pathways down her thighs.

Siferus pulled his enormous cock out of Pia and lowered her to her knees. It must have been obvious what he wanted to have happen next, and in response, a tentacle slithered it's way into her still tight pussy, beginning to thrust in perfect sync with the one piercing her ass. The tentacle slithered out of her mouth and began to caress her curves.

I'm pretty sure you know what happens next, Pia. He said, smiling and tapping his cock against her lips.

Pia snorted in dissatisfaction as the huge cock withdrew from her cunt. She was just seconds from a new orgasm, she felt, when her pussy was denied the tool for her release. Much as she hated being this wanton slut, she sighed in relief as the tentacle took her, and she was once again on the path to an orgasm.

Then the oral tentacle withdrew, a few droplets of spit and cum falling to the floor in the process, leaving Pia's mouth free.
"Ahhhhhhhh! Oh-oh-oh-oh myyyy...AHHHHHHH!", Pia moaned with primal intensity as she was again given the chance to speak.
Of course, her attacker did not do this out of consideration for her. The monstrous member, its ridges and veins glistening with semen and her own juices hovered before her face, touching her mouth.
"Ohhh! N-no, please! I- ahhhh!"

Siferus took full advantage of the yelling that showed her pleasure and he began to push the head of the giant cock past her lips, letting her tongue taste her own juices mixed with his own. The tentacle began to thrust faster and harder into her tight pussy, hoping that in her orgasmic bliss, she'd be a little more cooperative to give him what he sought. But, even if she wasn't, he would do it anyway.

You're rather talented with your tongue, Pia. I love the way it makes me feel. He chuckled. Another tentacle found it's way to her tight ass and began to tease it once again. Of course, with the cock now in her mouth, she couldn't object to Siferus pushing the appendage into the ring of muscle, beginning to thrust slowly at first, letting the hole accommodate him first, then beginning to thrust faster.

"Ahh-ohh-mmm!"
The lovely realease of being allowed to scream and moan was cut short by the monstous organ being showed into her. Not that Pia offered much of a struggle.
The fiercer tempo of the tentacle fucking her cunt made restistance hard enough, and the second tentacle now probing her tigh ass made it impossible.

The cock was now deep in Pia's mouth, sliding over her tongue and making her taste her own juices. Pia tried to pull her head back, away from the being fucking her face, only to push forward again as the anal tentacle increased its speed.

Siferus smiled down at the blonde girl that had his cock deep in her mouth, slowing his thrusting down to being gentle, not trying to gag her. The tentacle pumping in her anus slowed down while the tentacle pounding her tight pussy got even faster, trying to push her over the edge. He figured that if he could make her climax, who knows what she'd do in return.

He was hell bent to find that out.

"MMMMM!!"
With a mouth stuffed with a solid rod of maleness, Pia had no chance to moan or scream. Instead the blonde had to settle for a low, throaty sound. Because there was no way she could remain quiet. The changing pace, the aphrodisiacs, and even the taste of herself mingled with salty sperm from the spider-monsters big cock, all of this pushed her towards an orgasm.

..and then she came. Her whole body spasmed, twitched and shook from the reaction inside her. For a few moments, she was oblivious to the world, lost in some orgiastic inner world were nothing except fucking seemed to matter. Seeking support, she grasped at the first and best thing in front of her, her own assailant, and without even thinking, stroked his member with her hand.

Siferus only smiled as Pia began jerking him into her mouth, letting out a moan of approval as the tentacles buried inside of her began to piston in and out of her faster and deeper, alternating thrusts. Another tentacle began to play with her clitoris while two more coiled themselves around her bountiful breasts once again. He was determined to make her feel every little pleasure he could reap on her body.

He could feel the skill of her tongue as it danced along every throbbing vein and ridge of his cock. He leaned his head back, letting out another moan of pleasure, letting young Pia that she was pleasuring him.
