Under his skin:

"Can you show me?" Annabeth asked, after Percy had explained to her about being the host of Venom and how he was able to help him. Without needing to ask the alien, it did as the female requested.

"First I get you hard." Venom muttered in Percy's mind and Annabeth watched how a black substance, one she had already seen but thought it was Percy controlling some kind of liquid, oozing out of Percy's balls. It was strange to look at, but also quite fascinating.

It continued, until Percy's balls and soft dick were completely covered and started to move slightly, causing Percy to groan. "What is he doing?" Annabeth asked and Percy groaned before telling her that Venom was working on getting him hard. Only seconds later, the black substance retreated to present Percy's completely erected cock. "Damn, that was fast." The blond-haired female muttered before asking what else he could do.

Venom chuckled at her eagerness and showed the girl all tricks he had previously used, from the ring and tube to help Percy jerk off, to adding to his width or length and even the replica of his cock.

"So that's how you were doing it. But if you have a cock and can cover Percy's body, could you do a full body too. What I mean is, could you show me what you look like?". At this Percy perked up, he had talked about this with Venom too but didn't think they would get the possibility to use it. Percy grinned and said: "Sure! Venom, take over!".

Within a second, Percy was completely covered and hidden within Venoms muscular body. "Hello, little one." Venom said to Annabeth and she gasped. He was big, black and very muscular – he also was seemingly naked and rock-hard.

Annabeth gulped at the sight and watched as Venom stepped closer. "Do you want to have some fun, little one?" he asked in a deep voice at which the girl shuddered in anticipation. "What about Percy?" the grey-eyed girl asked, at which Venom chuckled before replying with Percy's voice: "It's OK Annabeth, I don't mind. I'm within him but still feel everything he does. If you want to fuck, go for it."

The female beauty gulped again but nodded eagerly, causing Venom to grin.

"Get on the bed, little one." the once again deep voice said and Annabeth did as she was told, already horny and eager to start their fun – Venom's little show had made her completely wet and she wanted to find out how it would feel. Just as she was told, she got on her hands and knees and waited for Venom to step closer.

Within a moment, she felt his hard tip at her entrance but before he penetrated her, he grabbed her hair forcefully, causing her head to bend back. With the other hand, he assisted his thick cock in sliding into Annabeth's moistened cunt and when he was seated, he moved it towards her hips.

Annabeth groaned at the size of his shaft and the warmth he radiated. "Fuck…" she muttered and Venom laughed deeply before saying: "Yes, that's exactly what I'm going to do. I'm gonna fuck you until your pretty pussy is red and sore."

With that, the big alien creature started to move his strong hips back and forth – slowly at first, but Annabeth wanted more and breathed out: "Yes, give it to me!". Venom couldn't resist and started to move faster, using more force when pushing forward. "You got a nice juicy pussy, little one." he grunted deeply and Percy could only agree.

Thrust after thrust, moan after moan – it didn't take long and Annabeth was at the edge of a heavy orgasm. "Gods, Venom!" she exclaimed and came, her pussy tightening even more and Venom came too, releasing a deep growl. Annabeth felt how Venom's cum was pumped into her and painted her inside white. 'Or is it black?' she thought, while imagining it inside of her.

Venom pulled back and told her to lay down. While she did as ordered, her previous question was answered as she noticed lots and lots of milky white cum flow out of her used pussy. The female moaned at the sight and watched how the creature slowly crawled towards her, perfectly lining his giant cock up with her cum-leaking cunt.

"Round two!" Venom grunted and pushed her legs apart as well as upwards. He held unto Annabeth's ankles while moving his hips forward and letting his thick shaft slide into her – moving inside was easy, he had not only covered his cock in his special lube, but his previous load of cum that covered Annabeth's pussy lips, as well as her inner walls, made a slick entrance possible.

"Fuck, that feels amazing!" the blond-haired female moaned and Venom chuckled deeply. "Thank you, little one. I am always happy to please you and your tight little pussy." he said before starting forceful thrusts. For quite a while his powerful hips moved back and forth, even lifting her up sometimes when he got especially eager, until he felt once more ready to come.

Venom let go of Annabeth's ankles and instead grabbed her above the hip. With a last heavy thrust, he pushed forward and simultaneously pulled the female's body towards him – penetrating her as deep as possible without breaking her tiny body.

Annabeth groaned in a mixture of extreme pleasure and bit of pain, while Venom grunted as he released his load of cum, which was even bigger than the one before. High from their good fuck, his long tongue flickered out. "That was nice, little one. We need to repeat that." he said after he was done and Annabeth stopped moaning. With a swift movement, Venom pulled his cock out and started to shrink down until Percy stood in his place, his softening dick covered with Annabeth's pussy juice and lots of creamy cum.
