Adrien lay in bed one night, trying to go to sleep, when a glowing light started spinning somewhere in his room. At first he decided he was seeing things and closed his eyes, one simply cannot trust their vision when they are half asleep. Then he heard footsteps coming toward him. "Adrien?" a female voice asked him, "you're awake aren't you?"

Adrien scrambled to turn on his bedside light. There, sitting at the foot of his bed, was Ladybug, but not the same Ladybug. She looked like the same person, but older. Now he was sure he was already dreaming. "What are you?" he asked sleepily.

"I've come here from the future," she told him. "I'm afraid things have gone very wrong in my world, and I need your help."

"Is this about Hawkmoth?" Adrien guessed.

"No, finding and defeating Hawkmoth will be a challenge for you, but you don't need my guidance on that. The problem I'm asking you to solve is one from our personal lives. Once apon a time, just as I was newly married, I was diagnosed with a fast growing cancer. It was stage four before anyone knew what was going on, and I died."

Adrien gave her a weird look, "but you're here now."

"There is a lesser known miraculous," she told him, "that allows the user to fuse with their past self and retain all of their memories. Once the fusion is complete, their former timeline ceases to exist, but all the people are preserved within their past self. Anyone who is directly affected by the time travel retains two sets of memories, while other people do not. This might be the cause of the Mandela effect. However, it only works when the holder is grieving the recent death of a loved one. My husband took his grief and traveled to warn me, when I was still a teenager, about my upcoming cancer diagnosis. Then he fused himself with his teenage self and we gained their memories." Ladybug blushed, "it was a good weird, going through high school with him, and remembering having been married to him in a past life. I got screened regularly, and they caught the cancer on time, but..." she looked down and her fingers clenched, "it was still harder to beat than they thought. The treatment left me barren at age nineteen. We were happy for a little while, we got married again, but then... it came to a point where we desperately wanted a baby. We looked into adoption, but it's a much more complicated process than we ever expected, and we couldn't help but wonder what a baby of our own would be like. We started toying with the idea of resetting our lives again, what if we had a baby back in high school when I was still capable of it? It got to where we couldn't think of anything else, and we made a sort of suicide pact. I killed my husband so that I could travel back in time and arrange a better future for the both of us. But I didn't kill him, because you are my husband, or... you will be my husband. You get what I mean."

"So if I understand correctly, you're asking me to have a baby with your former self? Now?"

"Well, that's just about it. We would be content with just one kid, but we always thought it would be nice to have three. If we allow for time for her-me-us to recover between pregnancies, you would have to start now to achieve that. I'm only asking you to commit to one right now, and then you can decide if you're up to having more."

"There are few things I wouldn't do to have the perfect family someday. If this is the only way, I'll do it," Adrien agreed, "but this is too awkward of a topic for me to bring up with her, you'll have to explain it to yourself for me."

"Unfortunately I can't do that for you. The stress hormone is a very good contraceptive. If she knows this is her only chance to get pregnant, she probably won't be able to. She has to be kept calm in order to increase her chances. It's probably best if she doesn't even know you're trying to get her pregnant."

"So you want me to get her pregnant against her will?!"

"No, she is me, and I'm giving you permission. This is for her own good."

"... so I have to hurt her now in order to help her later... I don't know."

"I'll talk to our families ahead of time so they get what's going on, and I'll be the one to explain to her once she's pregnant why you had to do it. She'll understand, especially when she gains my memory."

"Fine, but if we have to trick her into doing this, how am I going to... get access?"

"The first thing you need to know is who I really am. The way I was at her age, you wouldn't get anywhere with Ladybug, but when we're both in our civilian forms, you'd be surprised what I would have let you do to me if you'd asked. My hormones were out of control. Tikki, spots off."

Adrien didn't think it was polite for him to just stare at the woman that would one day be his wife, so he said the first thing that came to mind. "Even after a battle with cancer, you're still beautiful, Marinette."

That got a laugh out of the woman. "Remind me of that when you're waiting for my hair to grow back in, that's when I'll need to hear it the most."

"I'll tell you that every day." Adrien promised, "since you're here, can I ask you something? Why did you used to be afraid of me?"

"Because I love you, silly," Marinette bopped him on the nose, in the way that was familiar to him from Ladybug. "In my first life it took me forever to control myself around you. In my second life, the one I'm living right now, I had the advantage of memories from my first life to speed the process along. The third me, your Marinette, most likely won't gain control of her feelings until I fuse with her. Use that to your advantage. When you see her at school tomorrow, you don't have to seduce her just yet. Try to secure some alone time with her later in the week, that will make the next step easier. I'll also see if I can get you any intel on when her most fertile days are. Now, if you'll excuse me, my parents and father-in-law sent messages with me to their past selves. I'd better get those delivered soon or this will be even more trouble than I bargained for. Expect to see me again in a couple of days."

--

"I can't believe what I agreed to do to her," Adrien confided in Plagg. "My Marinette seems so much more fragile than Ladybug or the older Marinette."

"The older her has more life experience, so it makes sense why you would get that impression, but Ladybug? Come on, Kid, you know they're practically interchangeable."

"I keep reminding myself that, it's still hard to wrap my head around. She's stronger than she looks, she'll be all right." Throughout class, he'd been acutely aware of her presence behind him, watching the back of his head. He knew the behavior was nothing new for her, but it got to him like never before, being able to feel but not see his girl. Between classes, when he didn't have to keep his back to Marinette, Nino caught him staring at her. Adrien did his best to play it off, and covertly keep vigilante for a moment alone with her. Nino was gone to the restroom, Alya was talking to some of their other classmates, and Marinette was alone, drawing something in her sketchbook. Adrien approached her.

"Hey, Marinette!" Was all he'd settled on saying to her. He'd gone over a few plans for how thir conversation might go, but they all seemed like they were missing something. Was it too forward of him to ask her out, or should he come up with some other excuse to spend time with her? The topics he wanted to discuss most with her were the same ones he had to keep secret.

"Hi, A-adrien!" It gave him a sense of dissonance to look at her innocent face while remembering what he had been told; she'd let him do just about anything to her. He could take that two ways, one was that she was secretly perverted, and the other was that she trusted him deeply. It made him feel better to assume the second possibility was true.

"I've been thinking of you a lot recently," he told her truthfully. "I don't think we're as well acquainted as I would like us to be."

"Really?" It was cute to him how Marinette lit up, like she was hopeful he suggest they do something about that and get to know each other better.

"Yes, uh, would you like to go -" 'don't say go out just yet,' he warned himself, 'you'll scare her!' "get a smoothie with me sometime?"

"Yes!" she nearly yelled. "I mean, I already have plans today, and your schedule is packed tomorrow, so the next day?"

Adrien didn't question why she knew when he was going to be busy, all that mattered was that he'd scheduled a date, because whether they called it that or not, that's what it was.

As he walked back to wait for Nino, he bumped into a hooded figure wearing a Groucho Marx mustache. "Good job."

"Marinette?" he asked. "I thought it was going to be a few days before you were back. What are you wearing?"

"There are too many people here that I can't risk recognizing me! So, you scheduled a time with her?"

"Yeah, the day after tomorrow, smoothies."

"Smoothies! I used to imagine all the time that that would be a great first date. We must be on the same wavelength. This is good, you should be able to take her out a few times before you have to move forward. I decided to contact you again now so that you can plan accordingly. I had to go through her trashcans, but I've determined that she's going to ovulate at the end of next week. I've arranged for you to be invited over for dinner that same night, it should be easier to put her at ease in her own home. Preferably you should get her excited enough that she forgets the possible consequence of unprotected sex, but if she does ask about protection, I've prepared this." She handed him what looked to be a condom in a foil wrapper.

He turned it over in his fingers, it looked normal to him, but he'd only ever seen one in health class. "You did something to this one, right?"

Marinette nodded. "There's a few pinpricks that will open up under friction. Even with the holes, it will still hold back most of your cum, severely limiting the chances. If the tears stay small there's a chance she won't notice and you can try again, but if it opens up all the way, she'll know the condom broke and will be on extra high allert the next time. In other words, a broken condom is a one-time trick, if you try it and don't get her pregnant the first time, you're done."

"Understood." Adrien's fist closed around the foil packet. This was something solid for him to hold onto, to remind him he was really going through with this.

--

'Is this a date? It's not a date. It's totally a date!' Marinette - the teenaged one - sipped her smoothie, trying to figure out what the boy across from her was thinking of her at the moment. It wasn't wrong to assume that he was thinking about her, was it? He had asked her out, after all.

Adrien was busy being enamored with how resilient this girl was. She already managed life as a superhero with no one from her civilian life to confide in. In the next couple of years, she would be faced with a cancer diagnosis and a baby! (Okay, that last bit was going to be his doing.) He knew that through all of it she would stay strong.

Marinette found that she couldn't keep stuttering the whole time. The golden boy would sit and watch her patiently as she struggled to get her words out, allowing her nerves to dissipate until words became sentences and she was talking to him! Coherently! He enjoyed both listening to her, and the fact that she seemed genuinely interested in what he had to say, including when he said "I'd like to see you again, Marinette."

--

"My parents wanted me to..." Marinette rocked back on her heels, nervously, "invite you to have dinner with us."

Adrien found it hard to breathe. That was his signal. The older Marinette had put her family up to this, he didn't know how she'd convinced them.

"S-sure, I'll be there." Stuttering was supposed to be her thing, but his nerves were on fire. How was he supposed to handle this? Earlier that week they'd made it to a first kiss, honestly more progress than he'd been expecting, but still a far cry from what he was expected to do that night.

"Great! Then, I'll be seeing you." She kissed his cheek.

--

"Good evening, Adrien." Marinette greeted him. The two exchanged kisses on the cheek, they weren't going to kiss romantically quite this early in the evening.

Adrien greeted Marinette's parents as well. They returned the greeting politely, but watched him warily the whole time. Of course, Marinette was the only one in the house not knowing what was planned for that night.

Dinner was excellent, a savory pie with meat and vegetables. This truly was the best place for anything baked! In that same bakery, in a short while, he would be attempting to put a bun in the oven.

"I imagine you two would like to spend some time alone together before Adrien has to go home... why don't you go ahead and go up stairs for awhile?"

Adrien lingered a moment after Marinette left the room, trying to collect his nerves. He felt guilty, he'd been enjoying Marinette's company all evening without thinking sexually about her, and now he had to force himself to get into the mood. He was just about ready to go when Tom stopped him. "You're going to love her for the rest of your life?"

"Yes, Sir."

"And you realize that Marinette's disease is going to severely incapacitate her for awhile? If you do this, you could end up having to take care of a toddler by yourself while she's recovering."

"I understand."

"We're putting our trust in you Adrien, go on."

--

"I love everything about being here!" Adrien declared, sitting on the edge of Marinette's chaise lounge. I love the atmosphere, the food, and most of all, you."

"Me?" Marinette squeeked.

"Of course," Adrien stretched luxuriously, making an effort to seem completely relaxed. "Why wouldn't I love you?"

The vibe he was setting started to work on Marinette, boosting her confidence. "I love you too."

"That makes me really happy," Adrien threw an arm around her, "because all I want," he pulled her in close to him, "is to kiss you." He let himself get lost in their kiss, making it more passionate by the moment.

"Are you sure all you want to do is kiss?" She poked him playfully. He was starting to get excited and she'd noticed.

He groaned, but it was too early to give in. He needed her to be turned on enough that she wouldn't care if he wanted to take her bareback, he didn't think she was quite there yet.

"Later, we have time." He kissed her ear, then moved back to her mouth, gradually shifting her onto her back, and himself on top of her.

"Your words and your actions are saying two different things," she giggled.

"That's because I figured this position would be best for getting you bothered. I'm not moving again until I drive you crazy."

"You did that a long time ago."

The two quit talking in favor of kissing, and subconsciously shifting against each other. "Quit teasing," she panted.

"I'll tease you all I want," he replied, but moved to slip her pants off of her. She set to work on his clothes as well. As his efforts revealed more of her body, he became enthralled with the idea of getting her pregnant. When he saw her flat belly he imagined it round and swollen; her breasts, he imagined full of milk. He tweaked one nipple, and imagined the droplets of white liquid that would roll out. He was nearly desperate for her, but he needed to make sure she was feeling the same, needed to make sure she wouldn't ask him to pull out when it was time.

Now both fully naked, they continued to rub against each other, whimpering. Then Marinette bucked. It was an involuntary action brought about by her arousal, and the action caught the tip of Adrien's penis inside of her. They stared into each other's eyes.

"I'm doing it," he told her. She nodded. He slid deeper inside of her, and when he found her hymen, pushed straight through it. From there, nothing was stopping them. Adrien was proud of himself for getting inside without any sort of protection. They kept it up until they both felt a new feeling bubbling up inside them, then they both came.

"This will help," Adrien slipped a pillow underneath the sleeping girl's hips, to influence his sperm to swim deeper into her womb. They'd both passed out after their first orgasms, but while Adrien woke up a few minutes later, Marinette remained asleep on her lounge. He'd carried her up to her bed and propped her up with pillows, hoping she'd stay asleep all night. If she got up any time soon, his fluids would drip out of her and she'd realize what they'd done. If she didn't get up until morning, or at least several hours, the residue would have become less liquidy and wouldn't come out until she went to the bathroom. He knew that she knew he'd dumped a load inside of her, but if nothing prompted her to, she wouldn't drag up the memory until she needed an explanation for how she was pregnant.

When Adrien next saw her, Marinette was blushing and even regressed to stuttering a little, but seemed generally happy, and not at all inclined to avoid him. He guessed that she remembered the sex, but not specific details about it, she probably wouldn't be too happy with him if did.

A few weeks after, nearly a week after when the older Marinette said her younger self's period was supposed to be, Marinette came to school in tears - she looked scared. Adrien thought he knew what this was about. Suspicions only deepened when he heard her tell Alya "Thanks, but I can't tell you yet." Then she told him, "Adrien, we really have to talk."

Adrien followed her to a quiet area along the side of the school, where she dried her tears, and turned to face him. "P-please don't hate me," she started. The tears threatened to return.

Adrien reached out to dry her tears. "How could I hate you?"

"Because what I'm about to say could majorly complicate our relationship. I'm p-p-p-"

"Pregnant?" he guessed.

Marinette nodded. "I'm so sorry!"

"Why are you sorry?" he cuddled her to his chest. "I imagined that if this sort of thing were to happen, I'd be the one having to apologize to you."

"You mean, you already considered the possibility of me getting pregnant?" she sniffed.

"Yes, actually, you might want to sit down. I have something very important to tell you."

Adrien considered how he might tell her that he tricked her and got her pregnant on purpose without making her furious with him. His prospects were looking bleak when a familiar figure approached in a hooded sweatshirt. "I'll handle this," she pulled the sweatshirt over her head.

Marinette gasped, "you're me!"

"I am. Don't blame Adrien for this, this was your idea - well, it was mine, but you know what I mean. In a few years, you're going to become very ill. I'm afraid your last year of high school and your first year out of it are going to be miserable. You'll make an almost complete recovery, but the side effects of the treatment will leave you barren. I went through all of that already, but I want a baby so badly that I would be willing to go through it all again. That's why you have to have a baby now, while you still can. It's so that I can share your future, and you don't have to share mine. We've become slightly different people, but when I touch you, we'll become one person again. Ready?"

Both Marinettes put out a hand toward each other. ET phone home. (sorry) The instant they touched, the time traveler was gone, and Marinette had a vivid memory of Adrien as a grown man, dead on the floor, his throat slashed, and a bloody knife in her own hand. She remembered he'd asked her to do that to him, on the condition that she would use the power it granted her to rewrite their history and bring him back. She'd succeeded. He was alive and standing right next to her, a teenager again. He was no longer her husband, but she knew it was only a matter of time before they were married again. Best of all, in this life, they were going to raise a family.
