Siferus smiled at Pia. Feels good, doesn't it? Are you sure you want me to stop? Before she could answer, Siferus pulled her free and pulled her close, her nipples pressing against his chest, lowering her onto the top, not the head of his cock, slowly moving her back and forth, letting the veins and ridges tease her tight cunt.

"Noo.. please don't.. oh.."

Pia protested feebly but, as much as she wanted to deny it, her pussy demanded attention. Her soft cunt was wet against the hard cock benath her. Each ridge rubbed against her clit, sending shivers up her spine. Her nipples were hard against the carapace. She tried to push herself away with her hands.

You still resist? Admirable. The spider said with a chuckle. Her strength was easily overpowered by the giant spider, keeping her upper body pinned to him. He leaned down, kissing the sensitive spots on her neck.

Give into your lust Pia, and I shall give you pleasure beyond pleasure. He half whispered, half spoke making sure he was heard.

"Mmmmm..."
Pia could not help but respond to the soft kisses on her neck, closing her eyes with her mouth half open.

Give into your lust Pia, and I shall give you pleasure beyond pleasure.
"Noo, please, stop saying that!"
Truth to be told, Pia was closer to yielding than she liked. She liked the voice, and the features of that human face were strong and even, someone she might have found attractive. But those traits fused to a monster made it all so wrong, even if she was close to begging to be taken. Without thinking, she started to move her hips, letting her pussy slide along the spiders' huge member, soon glistening with her moisture.
"What are you? What have you done with me! I feel like.. My..I'm burning!"

Pia began rocking her hips, rubbing her cunt against the throbbing hard shaft beneath her.

All right, I'll explain. That fluid I made you swallow was an aphrodisiac. It sits in your system for about 3 orgasms. Only I can break you of it as well. He said, resuming his kissing her neck and sliding her along the meaty shaft.

Ohh..I knew it.. you.. you drugged me, you.. hnngh.. monster!"

Pia's heart was beating hard, she could feel her cheeks burning, all she wanted was something hard to bury itself in her tight but ready sex. She managed to place on hand on her cunt and carefuly stroke her clit, brifly touching the rigid member beneath it as well.
"Oh no! I don't want to..ahh..but I need it..so bad, please..", she moaned, no longer able to fight her urges.

Siferus smiled she admitted her need for him. He moved her off of him and spread her legs, lining his magnificent cock up to her tight wet cunt, starting to push into her, starting slowly and gradually began to get faster, rising her lust even more.

Pia was squirming with lust as the erect member slowly, ever so slowly invaded her tight but juicy cunt, gasping when it increased it's speed. She hated that the creature had so effortlessly made her abandon all decency, but her needs were undeniable.
"Please! Just.. just take me! Please fuck me hard.. I- I need it..", she half begged, half growled with lust.

Far be it for me to disappoint a woman. He said smirking, before his cock began to slam into her like a battering ram, tendrils coiling around her breasts once again, massaging as the assault on her pussy lips continued to intensify.

Is this better for you, Pia?

"Uhh..GAH!", eyes bulging and mouth open, Pia let out a shocked grunt as the assoult came faster and harder than expected.
Her pussy was wet and ready, however, and the arachnids hard member had no problems forcing the thight walls aside.
"Ahh.. I need.. Ahh! It.. Ahh!.. So..Ahhh! Much!"
Onlt the tentacles on her soft breasts kept her mounds from bouncing wildly with each thrust.

Pia was obviously enjoying herself, so Siferus released all her bonds, letting her move however she wished. He moved two tendrils to within arms reach, one on either side, wiggling them invitingly.

You can play with these too, Pia. He chuckled, waiting to see what she'd do with them, his cock slamming into her providing some advice of it's own.

"Ah-AHHHH!"
The beast slammed its cock hard into her pussy. The force made her breasts bounce. It was hard enough to almost hurt a little, but that was just enough to spur her on. Without even wanting it, she thrust against the movement with her hips, her greedy cunt wanting even more.

The creature teased her with its tentacles. Pia could think of several uses they could be but to, and with the aphrodisiac inside her system, it almost felt like a good idea. Revulsion and lust fought inside her.
"Please..Ahh.. put it against my clit. Ahh.. please.. I-I need it.."

The tentacles didn't move from their places, still waiting for attention, however another tendril began to rub itself against her throbbing clit, while another teased her anus.

How about one here too, Pia? He smirked.

"Oh-oh..s-s-so gooood!"
The tentacle on her senstive bud combined with the cock being slammed into her, every ridge and vein massaging the walls of her juicy cunt.
It was so good, yet so wrong.
She shivered as the tentacle teased her asshole.
"N-n-no.. Please..Ahhh! Ahhhh! Oh my..oh yes!"
The last was a reaction to a particulary deft stroke against her clit.

Siferus enjoyed watching this young woman throwing her cunt onto his cock. The tendril began working more intently on her clit as one of the others began to descend towards her warm mouth.

It seems you are truly enjoying yourself, Pia. I'm glad I can bring you such pleasure. He said with a smirk.
