Secret Killer

"How about you suck it?" Leon suggested with a grin on his face.

"I... don't think that's a good idea…" Lita muttered.

"Why not?" Leon asked. "Wait, let me guess… it's your first time seeing a dick?"

"What, no. I am a scientist, remember? I have seen hundreds of dicks. But of course, I have never sucked them," she sighed with a scoff.

"Then suck it." Leon placed his hand on Lita's head and said, "I will teach you."

Lita opened her mouth and showed him her teeth. They were pointy like a vampire.

"Are you a vampire?" Leon asked in a joking manner.

Lila licked the tip of Leon's snake and asked, "Do you believe in them?"

"If superpowers exist, then why not them? And I believe in everything and nothing at the same time. If I see one, I will start believing in them."

"They do exist." Lita kissed the tip on Leon's snake and said, "Supernatural creatures exist, and the government has hidden them in a secret facility."

"In area 69?"

Lita nodded and said, "Why else do you think it's so confidential that there is no information about it?"

Leon pondered for a while and uttered, "Maybe I will try breaking in someday."

"I will start sucking now," Lita said. She opened her mouth and started sucking the tip with her tiny mouth.

Upon seeing Lita sucking the tip of his snake with her cute face, Leon recalled the moment of his childhood when he inserted his finger into Layla's mouth when they were kids. 

Of course, it was an accident. At that time, Layla had a wild habit of biting everyone. So when she tried to bite Leon, he inserted his finger in her mouth to stop her. 

From that time, Leon had gained a fetish to insert his fingers in Layla's mouth.

After remembering the moment, Leon recalled Layla's face, which was the exact same as Lita was making right now.

Hence, he finally got an erection.

Lita had half of Leon's flaccid snake in her mouth, but when he got hard, her mouth was stuffed, and she couldn't breathe.

COUGH! COUGH!

She coughed and took out Leon's snake from her mouth. Then, she looked at Leon's erect snake and measured it with her hand.

She grabbed it with her two hands, and she had only managed to touch half of it.

"It's almost five times the size of my hand…" she muttered.

"Usually, it's only three for other girls, but you have a petite body, so…" Leon shrugged his shoulders and slapped his snake on Lita's face.

"Stop doing that!" Lita yelled.

"Open your mouth," Leon ordered and said, "I will teach you how to suck properly."

"But it's too big. The tip alone fills my mouth…" she said and opened her mouth.

"Nice. Now keep it open." Leon rubbed the tip of his snake on Lita's lips as though he was applying lipsticks with his snake. Then, wet the tip by brushing it on her tongue.

"Lick it," Leon ordered.

Lita licked Leon's snake carefully and wet it from all the sides.

"Now kiss the tip and then suck it like you suck lollipops," Leon said in a calm voice.

Lita did as Leon asked her to do and started sucking the tip with a cute and innocent face.

"Okay. Let's start now." 

  Leon slowly inserted his snake in Lita's mouth. Once the tip was in, Leon slowly moved his hips forward and inserted 1/3rd of his snake inside her mouth.

"You can close your mouth if you want," Leon uttered in a low voice.

Lita closed her mouth and stared into Leon's eyes as though she was waiting for his next order.

"I will push it a little deeper." Leon thrust his hips forth, and half of his snake had entered Lita's mouth.

"You can let me know if it hurts or feels uncomfortable," he added.

Lita nodded with Leon's snake still in her mouth and slowly started moving her head to suck it.

"Yes. Just like that," Leon groaned in pleasure.

'I was getting worried because I wasn't getting hard, but I guess it was just a normal mechanism of a human body,' Leon sighed in relief.

Lita tapped on Leon's snake and placed her hand on her head.

"...?" Leon didn't understand what Lita was trying to say.

Lita rolled her eyes, grabbed Leon's right hand, and placed it on her head. Then, she held Leon's left hand and placed it on her head.

"Oh!" Leon finally realized what Lita was trying to say. "You want me to move your head and use it how I want?"

Lita blinked and continued sucking Leon's snake.

Leon grabbed Lita's head properly and plunged his snake deep into her mouth, "You are such a good girl!"

Leon could feel the tip of his snake hitting the back of Lita's throat, even though only half of his snake was in.

'I shouldn't push further. If I do, I feel like I will break her,' Leon scoffed inwardly and continued thrusting his hips. 'But her mouth is so tight! It's almost as if I am fucking her.'

Meanwhile, Lita grabbed a pen from the floor and wrote something on the paper.

Leon could hear slurping sounds coming from Lita's mouth as his snake got wetter with every thrust. He increased his thrusting speed but didn't force it.

Suddenly, Lita tapped on Leon's leg and gave him the paper.

This was written on the paper: 'Pull it out when you are about to cum. I have to fill your sperm in the flask.'

"Don't worry. I will make sure of that."

After saying that, Leon continued thrusting his hips and continued enjoying the pleasure of getting his snake sucked by Lita's tiny mouth.

Suddenly, he released his load inside Lita's mouth.

"....!" Both Leon and Lita were surprised by that.

Leon glanced at Lita to see her glaring at him with teary eyes.

'Those eyes will just make me more excited…' Leon uttered inwardly.

Lita's mouth was stuffed, and it looked as though she was pouting, while in truth, her mouth was overflowing with Leon's venom.
