She was pressed against his back again, intermittently sucking at his earlobe and licking him as her arms held his upper body firmly to hers.

Her silky voice caressed his senses once more.

“I'm going to bite you again Van... are you ready?"

"Yes... yes... hnn..." he sort of wished he didn't sound quite so desperate.

She now kissed and Licked his neck, her saliva working its magic till he was numbed to all but pleasure. As such he only felt pressure there as she sank her fangs in, followed by a rush of vitality and hot arousal as venom seeped from them and into his bloodstream, from there making the pleasure center of his brain Light up like a beacon and endorphins further flood his system.

“You drank mine earlier, suckling at my breasts. Now I will drink of your vitality," he barely registered her whisper in his ear through the high he was on. She then delicately began to lick up the small amount of blood spilling from her bite mark, before closing her lips over it and sipping more blood. Somehow, it added to the pleasurable sensations of her venom now coursing through his body. He couldn't help but quiver, even snuggle in her coils from the pleasure, much to Serafina's further delight.

“You're so tasty..." she murmured before continuing to suck at the blood from his neck until the wound stopped bleeding. Like with her previous bite her saliva seemed to limit his bleeding when applied like this.

She then returned to a long period of pleasuring herself with her hands, lips and tail while her coils worked him thoroughly up and down.

All the while his heavy breaths spread her venom rapidly through him, every former effect of his arousal returning to its former level, and, then, intensifying.

It was so intense but he never wanted it to end. No longer did the pleasure frighten him, and his body did seem to already be reacting with less panic than before. No more did he feel the desperate need to cum, but rather only the pleasure of taking so much time to build up the orgasm.

Well, he wasn't fully content with building up his arousal again this way. On instinct he wanted to be inside her badly, but then wondered if it was feasible. He had managed to see the slit of her vagina up close a little earlier and it looked so tightly closed, the surface of her pussy lips bearing toughened skin, almost like the scales her vagina was so very close to, for protection he assumed as a Lamia had no inner thighs or hair to shield the vagina from harm.

It obviously opened some, he had seen the Lubricant that came out, but was it enough, her scales had turned softer, perhaps this applied to that thicker human skin too? Perhaps those lips were pliable enough to open further now? And as he tried to make it out in the rapidly dimming light filtering into the cavern he realized her vagina was in fact now gaping wide like a mouth waiting to be fed, her juices leaking out like drool. And under the formerly thickened surface the insides of her vaginal Lips and beyond looked soft and sensitive as could be.

Noticing Van's stare she brought him close to examine her lovely core in more detail. Located just where her smooth scales gave way to flawless pale skin, it was amazing how human it Looked, especially now that it was aroused and puffing up so much. But at the same time it seemed a good deal more muscular than a human woman's, judging by how strongly it quivered with her arousal.

The Lamia panted.

“Touch me Van... here.”

Putting an investigative finger past the lips of her vagina caused them to rapidly close around it and begin a powerful series of caresses, squeezes, and suctions. She moaned deeply while he struggled a bit to remove his finger. Once he had done so the lips opened wide again, looking Like a mouth begging to be filled.

“Look at how much I want you," Serefina breathed lustfully. "My second mouth has never been so excited before."

“S-second mouth?" He repeated somewhat warily, looking at his thoroughly squeezed finger, imagining that her muscular pussy would have been even more reluctant to Let go of his cock, and wondering just how that hot, wet, powerful chamber would feel caressing his manhood.

Trepidation vied with anticipation.

"Yes, you see animal meat is our main diet, human blood is a wonderful treat, but the semen of our mate is a delicacy, all the more delicious when taken in down here," she indicated with her hands to her lower mouth.
