Caius was gentle.
Besides the fact that this was his first time as Caius, this was also the first time, in both lives, that he was someone's first.
Also, he was technically asking for a lot from Kaya; he was asking her to give herself for the first time to him not just for their mutual pleasure but also for his goal of having a taste of her blood to further his evolution. All that came together to give him a sense of responsibility to make this good for her, to treat her with care that should become the basis of their relationship going forward.
Kaya felt differently.
For a while now, Caius' lower body hadn't moved. He had just a few inches of his member inside her and stayed right as he was to let her get used to it while his lips trailed lightly across the bite mark he had made on her neck. His fangs were only barely covered but kept safely away from puncturing her again.
But Kaya felt strange. She especially felt strange just hanging on to Caius with so much space between their nether regions even though a part of him was inside her.
Her arms tightened around Caius's neck first and her hands grabbed the back of his head, scratching his scalp under his thick head of hair as though coaxing him to keep trailing his lips over the bite mark that still tingled with a delicious mix of pain and pleasure.
While Caius was being respectful and gentle, as the seconds ticked by, Kaya's body began to become more and more energetic. She rocked her lower body in such a peculiar way that it didn't really register to either of them that her body was lowering onto Caius's dick… It just registered that he was entering deeper and deeper inside her.
By the time Caius noticed, Kaya pulled him by his hair until his face was away from her neck. Her eyes were open, staring into his Vampire-red eyes without an ounce of fear or worry as she made that final descent that brought their pelvises smacking into each other.
"Ohhhhh…." Kaya let out a long drawn-out shuddering moan as she threw her head back and raised her face towards the ceiling. But the very next second, she was looking into Caius' face again. Smiling.
Caius looked a little surprised and that surprise turned into almost-shock when Kaya leaned against his body and made him fall backward. He expected them to hit the ground as they had done yesterday when she made a similar move while they were kissing but instead, his back fell onto something earthy, writhing and slightly soft that was lifted about three feet off the ground. It took him a second to realize it was a network of vines.
'She can do that?' He asked in his head. He knew so much about Kaya's Nature magic but this particular use of it was new to him.
Kaya transitioned from having her legs wrapped around Caius' waist to having them on either side of his body as she straddled him with her hands still holding on to his hair. Her green eyes were glowing and the vines glowed a similar color as they continued to take shape. Slithering across the surface of the Alchemy Classroom door and sealing it shut even more than it already was.
When the writhing stopped, it was clear what Kaya had done; she had created a bed of vines.
For a moment, Caius thought about how bizarre it would be for anyone to walk in on this to see two students cozying things up in a classroom, doing unspeakables. And then he smiled and laughed in his head before returning his attention to Kaya.
He felt her clench and unclench around his member and the smile on her face looked so vulnerable. He pulled up from the 'bed' and wrapped his arms around her waist before turning them around until it was her with her back on the vines instead.
Caius took a moment to just take in her form, her breasts rising and falling in a steady rhythm as she breathed in and out in anticipation. One of his hands trailed down to grab one of her legs and pull it up while enjoying the feel of her smooth skin.
And then he pulled away, taking half of his member out only to slowly ease his way back as he began to quickly set into a nice and easy rhythm that had Kaya moaning into his ear with one of her hands in his hair while the other was on his back holding his body against her own.
Caius' shirt was open and in their closeness, her breasts, perky as they were, pressed hard into his chest. And with every motion he made as he thrust, he felt her nipples graze across his skin which drove him almost as crazy as the feeling of her tight snatch around his rod did.
Something inside him stirred. His very nature as a vampire was so in tune with the moment. The way her blood flowed was not lost on him and it riled him up so much that he was about to kick into a more aggressive thrust pattern.
But then he pulled up for a moment and Kaya was looking up at him with a nervous but happy smile on her face. Her green eyes twinkled and he could just tell that what she needed in that moment was tenderness.
And that was what he delivered. As best he could.
He seized her lips in a hard kiss and his grip on her thigh tightened and loosened alternately. Never to the point of causing her pain but enough for the tone and tremor of her moan to switch up with each squeeze and release. He put space between their upper bodies just so he could palm one of her tits. His fingers flexed around the globe and then his focus concentrated on her nipple. So erect it seemed like it would cut him.
The sounds of their lower half slapping into each other quickly became the loudest in the room. Even louder than Kaya's moans were. The squelching of splashing pussy juices that were being stirred up by Caius' cock also amplified the sounds and Kaya would have been embarrassed if she had been able to hear it.
Alas, she couldn't.
She hardly even heard her own moans.
You might wonder then, what DID she hear?
Well, she heard Caius' breathing most of all. She felt it on her skin and it had her body tingling which urged her to wrap her legs around him to keep him doing what he was doing.
Every stroke drove her mind farther and farther away from rational thoughts. Any bit of doubt she might have been feeling before they started was gone now. His presence… This moment, was all that mattered. And if she had been able to think rationally, she would have thought this was insane considering she had only known Caius for barely two days and he just revealed something huge to her. Pun intended.
Alas…
With a sigh that she let out just as her body shuddered with desire and pleasure, nothing else registered besides the fact that every time that rod pulled away from her and came close to falling out only to be slammed back in with intensity, she was being driven closer and closer to an edge she did not understand.
But Caius understood.
When Kaya's breathing spiked and her chest began to heave even harder as her shudders became more intense, he knew what was coming. He was close too.
More importantly, though was the spike in Kaya's blood.
This was it.
The highest possible peak of her arousal and the highest peak of evolutionary charge Caius could get from her blood.
"Oh, I'm… Something's COMING…!" Kaya let out and her tone hiked at the very end.
"Ugh, let it come…" Caius encouraged in a tone deep with passion.
Almost like she had been given permission, Kaya erupted. Her inner muscles gripped Caius so tight he could not resist releasing even if he tried. He jerked over and over again, releasing load after load of cum as deep inside her as his large rod had been able to go.
At the same time, he sank his fangs into the bite mark he had already made in her neck, causing her blood to spew out into his mouth in a moment of pure climactic and Bloodsucking bliss that eclipsed anything he had ever enjoyed so far.
