Author's note: I've heard there are two different kinds of time travel stories. The last chapter dealt with the kind where the future is changed as a result. For the next two chapters, let's examine realities where time travel does not change, but repeats itself to get the same results every time.

"We lost them!" Ladybug panted, locking the door. "Those mobs of fans can be crazy!"

"You're telling me?" Chat asked, drawing the curtains shut over the window they had climbed through. "They are going to catch us detransforming one of these days, it's just a matter of time."

"Not if I can help it. This hotel room the mayor lets us use is secure, they're not getting in. The real problem is whether we'll be able to get out of here before we're forced to reveal our identities to each other."

"That's not such a bad thing, is it, Bugaboo?" Chat asked, "We -" Chat stopped and swiveled his ears, hearing voices in a corner of the room.

"No way am I staying here for this, I don't want to see any of it. I'll be back in a few hours to pick you two up."

"Okay, thank you, Bunnix."

"Bunnix?" Ladybug whispered. "I thought a couple of fanatics from outside must have somehow got in, but it sounds like we have visitors from the future, but I can't see anything in here, can you, Chat?"

Before Chat could answer, someone flipped on the lights. "The boys might be able to see in the dark, but I can't any better than you can, and I'd like to be able to see." There was Ladybug, another one, with a second Chat Noir by her side.

"What's the matter?" The original Ladybug asked them. "Why did you come?"

"We knew that today was the day you would be revealing yourselves to each other, and that when we were in your place, we were visited by our future selves," future Chat explained. "I've always been glad for their intervention, it was a very hard experience for me."

Future Ladybug gave him a smug sideways look, which the younger duo couldn't understand. Why were they acting like there was an inside joke hidden within that?

"We're finally going to get to know each other?" Chat asked.

"You two are going to get to know each other very well."

"But, couldn't that be dangerous?" Ladybug asked.

"Depending on how you look at it, yes, we engage in high risk behavior all the time. It looks like your transformation is seconds away from wearing off."

Ladybug's hands flew up to her face, suddenly panicking, realizing her older self was right. There was nothing she could do, though. She turned back into Marinette.

"Marinette?" Chat asked.

Marinette turned her head to say something to him only to see him replaced with her crush. "Adrien?"

"Now that that's out of the way," future Ladybug told them, "we've got a pretty big reveal for you ourselves. Spots off." Future Ladybug dropped her transformation, making her situation apparent. More than just her identity, the magic had been hiding that she was heavily pregnant.

"We've started working on a litter!" future Chat proclaimed proudly, "but it's going to take awhile since we're stuck being humans that typically have one at a time and take most of a year to do that."

Future Marinette rubbed her belly, smiling. "It's been thirty-eight weeks now, the due date is in just two more. To think we've come back to the day I conceived this bundle of joy, only now we get to play the opposite role.

Adrien gulped, Marinette gasped and stumbled backward. "What's that supposed to mean?!"

"Just what it sounds like, I'll never forget the feeling of having my hand on my older self's belly, feeling her fetus wriggling under my fingers, almost ready to be born, and knowing I was conceiving the exact same baby in that very moment."

Adrien felt an involuntary stirring in his groin. "So this is what he meant by a hard experience," he muttered to himself.

"Hold on," Marinette panicked. "You know that I've fantasized of this sort of thing, but you also know I'm not ready for this."

"I do remember feeling that way, but trust me, you cannot afford to feel uncomfortable with one another. Allow us to show you how good it can feel to be together, physically, mentally, and emotionally."

Future Chat dropped his transformation and both time travelers began to undress themselves unhurriedly, much to the shock of their former selves.

"One thing you're going to learn about pregnancy is that it creates a pretty constant desire to reaffirm your bond, if you know what I mean. It's easy enough to deal with at first, but this growing belly gets in the way and we've become limited on what positions we can use. At this point I can pretty much only take it from behind, so I suggest you two hold off on trying it for a few months so you don't get sick of it ahead of time." Future Marinette knelt on the floor at the edge of the bed, knees spread apart, grasping the bed frame for support. Future Adrien knelt behind her, and after verifying her body was sufficiently prepared, he entered her.

Adrien and Marinette were kept a captive audience, capable of leaving the room, but fearful who was waiting for them outside, as well as being morbidly interested in watching copies of themselves going at it wildly. Marinette's hand brushed Adrien's and he grabbed it, the two seeking comfort in each other even though touching each other was what they in the moment most feared.

Finally, future Marinette hit her release, while future Adrien looked like he could have gone over the edge with her, but for some reason didn't. He pulled out of her, still throbbing. "Normally I do cum inside of her, after all, she is already pregnant, but we agreed today that we didn't want to make a mess. Plus, we don't do this very often." Future Marinette had turned around and taken his sex organ into her mouth, swallowing his ejaculation when he did let it go.

Future Marinette got up from the floor and sat on the edge of the bed. "Both of you, come here."

Adrien and Marinette aproached cautiously, Adrien especially, nervously about getting that close to a naked female. "Feel my baby," she instructed them. Both did without question, deep inside, they knew they wanted to.

"Now it's your turn." Future Marinette took hold of Marinette and started undressing her. Marinette just allowed it to happen in a sort of stunned stupor. Future Adrien grabbed Adrien and did the same thing. Even if their minds were being left behind, their bodies were responding. Adrien's underwear pitched a tent, Marinette's were soaked. These last two garments were soon discarded as well.

Future Marinette pinned Marinette's hands behind her back, and pressed the palms up against her own womb. "Relax. Focus on feeling the baby. Think about how you're finally going to have the child of the boy you love living inside of you." Future Marinette wrapped one leg around each of Marinette's legs and spread them for her.

"Ready?" Future Adrien asked, nudging him toward where their girls were leaned back against the edge of the bed. "She's ready, so take her." From behind he wrapped a hand around Adrien's penis and guided it toward Marinette.

The two mated, pressed together between their future selves. As they felt their combined orgasms approaching, the two leaned in to kiss each other, completely of their own will. Adrien's hands slipped around Marinette's waist and felt their future child as well. The child wiggled and sent both of them into their climax.

"Congratulations," future Adrien purred. "Now you two have a kitten on the way."

Adrien and Marinette lay together in the hotel bed, still connected at the crotch. The other two hand left them to go back to the future, leaving them to travel into the future the long way. "I can't believe we really did that," Marinette laughed. "Are we really going to be them and do all of that to our past selves nine months from now?"

"Of course we will," Adrien promised. "This is our future. It just takes a little bit of prompting to want to start a litter."
