Chapter 108. She Try To Prove Her Worth as A Succubus (Not Too Bad)**

Without saying anything else, she dropped to her knees in front of him and slowly slid her hands down his thighs. Her eyes were glued to his cock, which was already massive and twitching with excitement.

She could see the thick veins running down its length and how it pulsed with need. ’W-Whoa...! It’s the biggest I’ve seen...!’

She purred, "Mmm... impressive," and ran her fingers over the sensitive skin on his inner thigh again. "And so responsive..."

"I can tell how much you want this, Master. Your cock is already so hard for me."

"It’s okay... I’ll tease you plenty from now on."

Lilith’s hand went around Rex’s cock, but her fingers couldn’t quite wrap around the thick shaft. She stroked it slowly and carefully, feeling how hot and hard it was against her palm. Her thumb moved over the sensitive head, spreading the bead of precum that had formed there.

"Mmm... so big," she said, her voice thick with desire. "I enjoy a good challenge."

She leaned in, and her hot breath washed over his cock. Her tongue flicked out to taste the sensitive tip.

She felt a rush of pleasure at his taste, realizing it was too good for a human to possess such a godlike cock. Her tongue moved around the head, feeling every ridge and groove, while her hand kept stroking him in a slow, steady rhythm.

’Oh my lust... he’s so fucking huge,’ she thought, her pussy already wet with desire. ’I’ve had a lot of cocks in my mouth, but this one... this one is different, and he’s human...’

She opened her mouth wide to fit him in, and her lips stretched wide to fit him in. As she bobbed her head, her tongue moved along the underside of his shaft, pushing him deeper with each stroke.

GLUCK! GLUCK! GLUCK! GLUCK! GLUCK!

It felt too much—hot, wet, and tight all at once.

She moaned around his cock, "Mmmph... fuh... mrrrgghhh..."

The vibrations added to the feeling. As she kept working on him, her free hand moved to cup his heavy balls and roll them around in her palm.

But even though she was good at it and liked it, she was having a hard time. His cock was just too massive for her mouth to fit all the way down.

It was pushing against the back of her throat and making her eyes water, but she couldn’t quite fit it all.

’Damn it,’ she thought, her competitive side coming out. ’I’m a succubus... I should be able to deal with this... but he’s just... too damn massive, and I can feel it getting bigger inside.’

She pulled away, gasping for breath, with strands of spit connecting her lips to his throbbing cock. With each breath, her huge breasts moved up and down, and suddenly, an idea struck her.

"Fuhhh... Master," she said, her voice thick with need. "Let me give it another shot with my massive tits this time."

She put herself in front of his cock so that her huge breasts were right in front of it without waiting for an answer. She pushed them together, making a warm, tight tunnel of soft flesh.

She smiled at him with a wicked expression on her face and looked up at him. The valley between her breasts was deep and inviting.

"Watch this, Master," she said, her eyes dark with pleasure.

She started to move her breasts slowly and in a rhythm, sliding them up and down his shaft. And as always, he had felt that sensation of soft, warm, and very tight breasts, where her breasts were so massive that they completely covered his cock, making a perfect tunnel with lots of friction.

"Fufu... it’s twitching violently inside my tiddies~!" Lilith felt proud looking at his cock. "I can’t believe I can make Master like this..."

"Does that feel good, Master?" she asked, her voice full of pleasure. "I’m sucking your cock with my tits."

"Can you feel how tight they are? They’re squeezing every inch of your cock."

"It’s not bad, but it’s not enough." Rex said until the tip of his cock is sticking out of her tits.

"W-Whoa...! It’s getting bigger again... but I won’t lose this time!"

She sped up, and her breasts moved up and down his length faster. It felt amazing—hot, wet, tight, and very good. Her hard, sensitive nipples rubbed against his shaft with each stroke, adding to the pleasure.

Lilith still had a hard time, even with this creative approach. Rex’s cock was just too big for her breasts to hold all of it.

His cock tip kept poking out of the top of her cleavage, and the thick head was wet with precum and saliva.

She thought, "Fuck," and her competitive side got even stronger.

’I can’t even use my breasts right on this thing. He is just... too damn big.’

’Even though I know he’s a human, getting sandwiched between my breasts like this makes him still resist it...’

’But still... I have tried even harder!’ She looked up at him with both anger and determination.

"Master, I... I don’t think even my tits are big enough for this," she said, her voice a little out of breath. "You’re just too fucking big, but I’m not giving up yet."

She leaned in closer and licked the tip of his cock that was sticking out of her cleavage. "Sluuurrrppp..."

"Let’s try something else," she said, her eyes shining with new determination. "One way or another, I’m going to make you cum crazily on my tits, Master."

Rex said. "Your tit-pussy feels average, but you can at least feel proud for not making me feel bored."

"You’re worthy, but... by one tiny bit."

Lilith’s eyes flashed with frustration and new resolve when Rex made fun of her. She was already competitive because of the challenge of his huge cock, but now she wanted to prove herself even more.

"Worthy?" she said, her voice full of anger. "Master, I’ll show you worthy!"

"I’m a succubus, and no mortal cock is too big for me to handle! Just watch and learn."

She pushed her huge breasts even closer together with both arms, making the tunnel even smaller and tighter. The pressure was strong, and she could feel every throbbing inch of his cock sliding between her soft, warm flesh.

"Mmmph... fuh..." she moaned, and her tongue flicked out to lick and tease the tip of his cock as it came out of her cleavage.

"Bleergghh..." Her saliva was already cascading down, soaking her breasts and exacerbating the friction.

Her mouth went down on his tip, and her tongue swirled around it as she licked and sucked. She started to drool more, and the extra saliva dripped down his shaft, making the mess even wetter and messier.

GLUCK! GLUCK! GLUCK! GLUCK! GLUCK!

She kept moaning, "Mmm... mmm... I can see your cock... It looks like it’s at its limit..."

Her mouth and breasts worked together to drive him crazy. Her drool was running freely now, making his cock look thick and wet.

It was so intense that it looked like something from an animal who craved sex.

"You are only going to make me cum without feeling any satisfaction," Rex said.

Lilith didn’t care about hearing him say that, and she was determined to make him cum so that she could prove she was a real succubus. She was going to win this challenge, no matter what it took.

Her competitive nature had taken over.

She could feel his cock throbbing against her tongue, and she knew he was close. Her breasts moved increasingly rapidly, while her mouth functioned with greater intensity, diligently sucking and licking with fervor.

"I won’t stop until you cum for me, Master," she moaned, her voice muffled by his cock. "Please cum all over these tits!"

"Prove to me that you’re worthy of a succubus like me."

Rex groaned. "Ahh, fuck... alright then! Here you go!"

His cock throbbed and twitched, and then he came hard and fast. Thick ropes of cum shot out, covering Lilith’s huge breasts and even hitting her face and chin.

SPLUUUUURRRRRRTTTTTTTT~!

Lilith moaned, "Ahhnnnn... fuck... yeessss~!"

Her eyes rolled back in pleasure as she felt his hot seed painting her breasts. She didn’t slow down or stop, but instead, she worked even harder to extract every last drop from his cock.

She felt his cum hit her face, and instead of pulling back, she moaned even louder and licked her lips to taste it. Her tongue ran along the edge of her jaw, collecting the thick seed and bringing it to her mouth.

She purred, "Mmm... so good," and swallowed it down quickly.

"Master’s special semen syrup... is tastier than any semen I’ve had."

Lilith sat back on her heels and looked down at the mess she had made when the last drops finally came out. Her breasts were covered in thick, sticky cum, and some of it was dripping down to her lap.

It was all over her face and neck, and she could feel it cooling on her skin. She looked up at Rex with a smug smile and licked her lips again.

"I did it, Master," she said, her voice full of pride. "I made you cum all over my face and tits."

"That proves I’m worthy."

"It’s a shame that... it’s still not enough! Try proving me even more." Rex challenged her more.

She didn’t answer him; instead, she bent down and started licking the cum off her breasts to clean them. She was very thorough, making sure to get every last drop.

Her tongue dragged across her sensitive nipples, sending shivers of pleasure through her body.

She cleaned her breasts and then went to her face and neck, licking and sucking up all of his seed. She moaned as she swallowed it, enjoying the taste of him.

Finally, she looked up at Rex with those bright red eyes when she was sure she had cleaned herself up.

"So, Master," she said in a low, sexy voice. "Do you think I’m good enough now?"

"Yeah, yeah, continue."

She got up, her breasts still heavy with cum, and reached out to him. "Okay, master, let’s clean you up first."

"Then... I think it’s time for round two."
