"Fuckkkk~I can't get enough of you~I can't stop~Your dick is so bigg~"

"Nngh! B-Brittany! Relax!"

"No~Fuck no~Haaah~I need this~God I love you so muchhhhh~"

Jin normally tests his research to make sure that there would be no negative side effects or anything of the sort.

"Ahhhh~Fuck me~"

When creating powerful technology or something dealing with organic material, such as the human body, it is imperative to double-check your work so nothing bad happens.

"You like that~You like how I bounce my ass on your dick~Fuck~I want you to get me pregnant~" Brittany started kissing Jin's lips, pressing her tits against his chest as her hips kept grinding on Jin's cock.

However, today, Jin didn't do such a thing. Well, that's not true. He did test the stimulant to make sure nothing bad would happen, and nothing bad did. However, he failed to take into account the shift in the body's hormonal balance.

"Cum inside me~Blow your thick load of semen in my womb~I'll take it all~I want it all~Cum inside me, baby~I want your cummmmm~"

After Brittany used her power and settled down in Jin's room, she started feeling weird, but not in a bad way. She simply started craving something.

At first, Jin thought she was hungry, so he told her he could go get her something to eat. But she told him that she wasn't hungry.

When he asked what she wanted, she looked at him and said, "You."

Jin was flattered, thinking that she was simply lusting for him, which was a normal occurrence after they started their physical relationship. But once he saw her breathing heavily and her pupils turn into hearts, he knew he was screwed, literally.

She tore off her clothes, then kept Jin in place with her telekinesis, taking off his clothes as well.

He didn't expect her to be so strong, and couldn't break out without needing to actually try. But he was so on board with having sex that he didn't even bother doing so.

That was until they continued to have sex for the past six hours. For the first few hours, he could handle it, but after that, he started to feel a bit tired. He was shocked that he was feeling this way and didn't understand why; he still didn't, but his mana wasn't helping him at all.

"S-Shit! I'm cumming!" Jin came inside Brittany.

"Yessss~I can feel it~Mmmnnn~So goooood~"

"S-So, we're done, right?"

"Done? Baby, I haven't even cum yet. Besides, I know your balls still have a lot of spunk left in them for me to milk. I'm not stopping until I've milked you dry!"

"N-No, no please!" Jin begged

Brittany simply chucked and started fucking Jin again, milking him until there was nothing left.

---

"Nngh! Wow! I feel amazing!" Brittany stretched her arms, feeling energized and ready to stop some criminals. She was lying down in bed, not up just yet, and had a satisfied smile on her face.

"I wonder what Jin—" She felt something on her chest, seeing Jin lying between her boobs slightly on top of her.

"Aww. He's so cute. While he won't admit it, I know he likes being a bottom." Brittany stroked his hair, kissing his forehead, then wrapped her arms around him for a bit.

She didn't even care that she shared him with Addison and Angela. All that mattered to her was that she got to have him, and she was happy.

"Hmm? What's that wetness dripping down my legs?" She removed the covers to see the entire bed completely soaked in cum from both of them.

"W-Wait a minute!" Everything came back to her, how she had her way with Jin until he passed out, and even after he had passed out.

He had cum buckets inside her, and she didn't allow him to stop.

"N-No way. I-I thought that was an intense wet dream. Wait, Jin." She gently rolled Jin off her and onto the bed, feeling his semi-hard dick exit her insides, which made her moan slightly.

"Ahh~W-What?" Tons of semen poured out of her, more than what she thought was possible, but then when she looked at Jin, she saw that he was a shell of his former self, looking like a mummy with how devoid of life he was.

"Shit! I killed Jin from sex! Is this truly death by snu snu? Jin! Wake up! Don't leave me! Who will help me take care of our kids?! Wait, why am I saying that? Fuck!" She started shaking him to get him up.

"Ughh." Jin slowly opened his eyes, feeling drained of all his mana. When he locked eyes with Brittany, he froze.

"Jin."

"C-Can it wait until after I've recovered? I'm a bit weak right now." He asked in a low tone.

"Oh no! Jin!" She hugged him. "I'm so sorry! I don't know what came over me! I-I couldn't control myself, and I took out all of my sexual frustrations on you! Please forgive me!"

"Huh? Oh, don't worry about it. It was hot. Besides, it's not your fault. Technically, it's mine."

"Huh? What do you mean?" She stopped hugging him.

He explained to her how he forgot to take into account the hormonal balance of a person when creating the new stimulant. Then he said something else that she never expected.

"You see, I use mana, like all the time. And because I use it around you a lot, your body naturally started to pick up on it, slowly transforming you to be able to use the power." He explained.

"What does that mean?" Brittany wasn't following.

"Well, it means that your body needed a way to circulate mana, but since you don't cultivate, your body couldn't keep the mana in your body permanently and needed to expel it. But before your body could expel it, your hormones spiked like crazy, causing what was currently stressing you out to skyrocket, which was your sex drive. And so, once we started having sex, your body took that as a sign to cultivate and use me as an energy source."

Brittany's eyes widened. "Wait a minute. I read comics and shit, so I know of this. Are you telling me that we...dual cultivated?"

Jin nodded. "That's right. I didn't even know until I was already too tired to fight back, haha."

He placed a hand on her left tit, feeling her heart underneath. He didn't need to do this, but he simply wanted to touch her boobs.

After injecting his mana into her body to sense what was going on, he saw what he would never have expected.

"Yup. A mana circle appeared around your heart. Brittany, you're a mage."
