Within her mouth her tongue would continue to enwrap him and take the sensations further, while together with her lips she sucked him in earnest. Intermittently she would release his cock and again nipple fuck it before going back to fellatio or doing both at once, sucking and Licking the head of his member while massaging the base with her breasts. All the while her rattle continued a steady humming vibration below and about his scrotum, his increasingly engorged balls throbbing with the rapid beats.

Van's member continued to twitch strongly inside her mouth, even more when her dexterous tongue began licking up the precum that seeped from the tip of his cock like Lava from a volcano. His enwrapped arms jerked as well against the restraint, his hands frantically clawing at the smooth floor, trying to find purchase, something solid to hold onto and use as leverage to thrust his hips, but all he could grab was her cloak. And so he had to accept the careful leverage her coils were giving him, though it was not enough for him to thrust as hard as his body was desperate to.

His eyes reflexively rolled back in his head. It meant he was nearly there, he had to be. His balls felt so tight, so full. And yet while he continued to feel on the crest of a massive orgasm, it wasn't hitting him.

Why couldn't he cum? Was it the venom? Was this what she had meant? He wanted to cum so bad. No. He NEEDED to cum! It was actually frightening just how strong his arousal was becoming. He'd never felt anything of this level before. He had to cum. He was sure he'd lose his mind soon if he didn't. He'd never been in this state for so long before, his body wouldn't allow him to be.

“Serafina... please... I- can't- I need- ahn!"

He involuntarily threw his head back, his eyes clamped shut, his speech devolving to unintelligible moans as she picked up the force of her triple stimulations. She wasn't ignoring him, she seemed to have done this in response to his plea.

This was it. There was no way he could take this. If he didn't cum he'd go insane, but at the same time felt that if he did cum he would blow himself apart. The pressure inside him as his muscles tensed in preparation was incredible.

Then, somewhere in that storm of pleasure, a dam seemed to burst inside him. And he came.

And came.

And came.

For Van, Like most men, a good orgasm could be compared to a wave of water breaking on a beach. The pleasure would rise, reach an explosive height as it crested and break fairly rapidly after that.

That didn't happen here. This was more like a tsunami. There was no visible back to this wave, just a sea of roiling pleasure, and it did not break but continued to surge onward Like a river. It shouldn't have been possible to cum for this long, even if his balls had felt strained and full. Yet, unknown to him. with his body's Liquids being rapidly converted into seminal fluids by her venom, he had an extra supply.

All the while Serafina's lips retained a strong seal around his manhood, guzzling the contents of his orgasm as if it were the nectar of the gods.

It felt so good, but it was so different, so powerful, even frightening. His cries of pleasure had begun to mix with cries of fear and panic when it at last became too much for his mind and body to bear.

He blacked out.

Van would later guess he was out for less than a minute, during which his orgasm had reached its end. Serafina seemed to have been so busy sucking his cum out that she wasn't even aware he had lost consciousness.

“Mmm... it was even more tasty than usual. Using venom really makes a difference" she remarked, for the moment sounding simply cheerful rather than seductive.

Van, however, could only think of how even with venom he hadn't managed to Last that long. Tears, now of shame, flowed from his eyes. "I'm...

I'm so sorry... I couldn’t hold back... I..."

She drew him close.
