Siferus moaned softly into Shai's passage, sending pleasurable vibrations through her body when Shai started to swirl her tongue around the head of his shaft, her hands complimenting her skill as they gave the entire cock an amazing feeling of pleasure. Siferus nearly came at the beginning, a small bit of presemen spurting into Shai's mouth. Luckily for her, he caught himself so he could deliver a much bigger payload of his nectar for her, although he knew it wouldn't be long. She'd probably redouble her efforts for it now.

He had to focus on her sex and pleasing it. The tendril moved away from the swollen nub of pleasure only to have the tip of the beast's tongue flick across it gently, teasing it but pleasing it at the same time.

Siferus moaned very loudly into the petal lips, causing very intensely pleasurable waves to shoot through Shai when she redoubled her efforts to please the spider, his cock spurting hot seed into her mouth. The liquid was hot and thick as it flowed into her mouth for what seemed to be an eternity before after a few twitches, it was spent...but still hard?

Siferus continued to tease her cunt with his tongue for a few more moments after he had cum like that, pressing his tongue past her petals into her waiting warmth, slurping her nectar loudly and seductively, the sound definitely making it to Shai's ears.

As Shai continued to work his long thick meat diligently, Siferus would moan louder and more frequently into Shai's petal lips, the vibrations providing certain to provide more pleasure to the already horny woman.

Siferus lapped up the orgasmic juices of the snow haired girl eagerly as it flowed into his mouth, moaning in sheer delight. Her nectar was sweet to the taste and he wanted more. His tongue continued to dart around until it found her g-spot, and when he did, his tongue began to swirl around it repeatedly, taking as much of her juices into his mouth as he could.

These juices of yours are rather delicious, Miss Shai. But, I think you'd rather have me fuck you again, wouldn't you?

At the response to his question, Siferus laid Shai back softly against the sands, his hands slowly pulling her legs apart enough for him to fit between. The tip of his shaft pressed softly against her petal lips at first, but eventually pressed hard enough to push past them and into the soft tight passage between Shai's legs. Despite the couple hours of sex, her walls were still as tight as when he first caught this beautiful girl.

You're still incredibly tight, Shai. Your body is amazing... He said, giving her a few moments to speak before pressing his obsidian lips against the cherry red lips as a lovers does on the first kiss.

When the lips of the two locked, Siferus began to slowly thrust his long rod into the body of the scientist, her breasts jiggling more violently as the thrusting got more and more intense...

Siferus began to slide his enormous cock in and out of the candied cunt of the beautiful scientist. She really did have an incredible amount of stamina. Possibly more than Siferus had. Siferus was nowhere near spent, but he was beginning to notice a slight waver in his energy. He was beginning to get tired.

Lewd squishing noises and the smell of sex filled the air around the the scientist and the spider. Siferus watched as Shai began to play with her beautiful breasts, so Siferus gave a new twist to it. A tendril slithered it's way up her torso and rested between her round breasts. It began to slide back and forth, encouraging Shai to push her breasts around it.

(I thought I replied to this already. I offer my sincerest of apologies to you. Gomenasai, Shai.)

The spider watched lustily as the snow-haired scientist pressed her breasts tightly around the thrusting tendril as it continued to slide itself between her glorious breasts. The tendril began to swell slightly, presemen dripping between the orbs of flesh, lubricating them.

His cock slammed in and out of Shai's candied cunt like an organic battering ram, hitting her cervix with each thrust inward and dragging against her g-spot with every retraction as her walls gripped tightly at the long shaft. The behemoth of a cock began to swell inside of her, showing her that he was about to cum yet again.

You're close? Then allow me to help you with that... He responded, quickening his thrusting, slamming in and out of her tightly clenching folds faster than he had shown her earlier, trying desperately to make her cum so he could cum himself.

The tendril had no such inhibition. When she tweaked her nipples, she could feel the rapid throbbing of the tendril, which was about to cum and hard. The tip of the tendril poked out from between her breasts and shot it's load of seed straight at Shai's face, coating it with the white warm substance.

Siferus was not ready to fill her with his seed yet. He always believed a woman should cum first.
