Some hours passed since Mark entered Yuri's lab.
For now, both getting the insects and evolving to the Tier 2 would take some time. So, Mark pushed those to the back of his mind.
There was a solid metal handcuff in Yuri's lab; Mark took it and tied his and Dona's hands together. He didn't want them to separate from each other due to some accident, so the handcuff was handy.
"Drink this. This will remove your exhaustion," Yuri said, giving Mark a bottle of black water. He was, at first, a bit stunned, but then, he sighed.
It was water from that Black River from the Demon World!
The Black River that could remove exhaustion of both Mind and Physique. Why hadn't he thought of making a bottle and somehow carrying it around? It would have been so much easier.
Where did a Scientist from the Hunter World get it in the first place?
Taking the water, he took a sip and then drowned many mouthfuls.
Immediately, his tired mind and body were revitalized.
He felt much, much more confident in himself.
But he didn't let himself reach his peak potential at this moment. He used a simple Heart Input on the nearby wall and lost 0.1 Mind power due to a failure.
[Mind: 9.9/10 (Tier0-Pinnacle)]
If he reached back 10 points, he would once again start to have that weird out of body sensation. His mind would start showing him the world surrounding him through infusion of information as if he had a third eye.
He would start to feel his mind somehow chaotically projecting his surroundings into his mind like broken pictures. When he had reached (10) in Mind, it had changed him somehow, and from then on, that was something that happened constantly when he reached his full potential.
It was a sickening feeling.
It wouldn't irritate him so much if he reduced his Mind power. That broken-picture out-of-body-bullshit would turn off.
That was why that became less of a problem after he entered this World. He hadn't been full ever since.
He turned aside and helped Dona drink from the bottle, too. She was as usual, clumsy, and tried to bite the bottle, but he held her mouth and made her drink slower.
"Watching her, I am reminded that not all demons are intelligent like you," The Scientist commented and took notes. Her dark eyes were full of curiosity and wonder.
"Where did you get this water from?" He asked.
"There is supposedly a small black pond or something of that sort inside the Mega-Dungeon. Drinking from it makes all exhaustion vanish. Some Hunters enter the Mega-Dungeon just to get this stuff. Very magical. It can heal all sorts of diseases, poisoning, and much more. It is called the panacea for all, or god's blessing, or so around here."
He had once guessed that the Black River's water might be able to heal poison.
Mark looked at the half-empty bottle speculatively and didn't let Dona drink the rest. She was fully healed. Losing the rest of it for nothing would be a waste.
"Urr…" Dona growled and tried to snatch the bottle from him, but he didn't give it to her. She pulled on the handcuffs with a wronged expression. Her drowsiness from earlier was gone.
"You can't drink this. We might need this later."
"I have more of it. At least a tankful. You can give it to her if you want." Yuri walked to the side and clicked some buttons. From the side, a glass pod opened up, and she sniffed as she began working on something.
Mark let go of the bottle and let Dona drink what she wanted. He couldn't help but smile at her antics, and unconsciously, he patted her butt. She wiggled it gently. It felt different with the clothes now—he couldn't feel her ass so clearly anymore.
Annoyed, he let his entire hand enter her pants and immediately began fingering her. Dona's expression changed into one of bliss, and her thighs tightly wrapped around his hand.
Smiling at her innocent act, Mark took her into a princess carry, and without stopping his one finger from twiddling inside her warm hole, he let her lay on the couch, and as Yuri watched dumbfoundedly, he tore away Dona's pants.
Dona purred in anticipation and pulled at his trousers until his rigid manhood jumped out and pressed against her stomach.
She seemed to know what to do as she wrapped her hands around his neck. Leaning down, he kissed her deeply. His tongue entered her warm mouth and played with hers till she was entirely defeated, and then he pushed both of her hands against the couch.
She spread her legs wide, and he made his tip press against her slit. His kiss became even more intense, and her hands clasped against his as he pushed in. Her warm, slick insides wrapped around his cock tightly, and he groped her breasts as he pushed deep in.
"Urr~" Her hands clenched on his. Her toes sank into the couch.
Saliva dripped to the side of her lips as they broke the kiss. His gaze was intense as Mark looked at her red eyes and began to thrust deep into her. As he moved down to kiss her neck, he could feel that scent of wild grass, too.
His cock was huge, so he could soon touch her cervix, and after every time he rocked it, she purred more and more intensely. Taking one of her legs, he placed it over his shoulder and continued thrusting.
Dona's face changed wildly in expressions, her bliss evident with each one as she shook under each of his moves.
"URR!"
"Ruu…"
"Nm…"
Grr!!!
He kissed her neck, bit her ears gently, and even licked her cheek.
When he reached a limit, he pumped deep into her, felt her pussylips tighten around his shaft, and exploded all his load into her sacred hole.
Dona released her earth-shattering moan, and her own liquids exploded out into his crotch. Mark laughed. "We should have done this before bathing!"
His slick shaft fell out of her hole, and it dripped with her liquids. A lovely smell began to inundate the lab.
Dona pulled his face closer to her and breathed out warm air for a second before she began to lick his cheeks. Then, she just giggled, and Mark giggled too. But just as he was feeling satisfied, he felt a cool hand on his cock and looked at Yuri curiously.
She squeezed his cock with one hand and moved down. She cupped her other hand below and collected all his jizz and liquids on his cock into her hand. Then, she curiously stood up and looked at it.
Mark's eyes glittered. "Now you've made me interested in you."
The Scientist dipped a finger into the liquid and placed a drop into her mouth. She curiously thought for a second and then nodded. "Indeed, this must not be how human liquid tastes. This is sweet. I'll have to compare data from the internet to be sure, though. I wonder if this can make a human pregnant."
She then looked at the blissed-out Dona and pondered. "This was a surprising turn of events, but I don't mind if you do this often. Just let me do whatever I want, like collect samples."
Mark pulled the Scientist closer to him and touched her crotch area through the clothes. Even through the clothes, he could feel how wet she had become. She was dripping crazily. No wonder her face was so red.
She yelped slightly.
"You are so wet, yet you act like you are so indifferent." His fingers played their magic as he spoke and gently aroused the woman's clit.
She wanted to speak, but she couldn't even let out a word; her face was red all over, and she was panting as his hand made her more and more aroused through the clothes.
She held his shoulder with one hand and just panted as his fingers moved.
Ngg!
She moaned as one of his fingers intruded into her insides through her cotton pants. Mark could feel her hymen inside, and he didn't break it.
Instead, he played around with her crotch, and the sensitive woman literally shivered as her dam broke and her cum dripped out into her pants like a small geyser.
She leaned against him blankly for a second before she took in a relieved breath. "Never knew it was so much better when someone else did this for you. My own hands pale in comparison."
"I thought so, too," Mark smirked.
She chuckled dryly and shook her head. "Now I can easily compare my liquids with you people's. By the way, don't spill these all over my lab. And thanks for this. Now let me go put all this liquid in a container before it goes bad."
He could see that she was red in the face, and he didn't want to make it too quick. Now, he had a genuine interest in her.
She stumbled towards her lab table, hiding the blush on her face while liquid dripped down her pants. He couldn't help but smile.
Dona looked at his cock and cock alone. He gave her one more go; the Scientist had made him a bit excited.
