Note - Anyone looking for serious Marichat fanfiction needs to look elsewhere. I respect that it is the most popular variation of Lovesquare, but I'm just not that into it. I'm not going to write anything that I wouldn't want to read myself. Marinette loves Adrien and he loves Ladybug, in order for Marichat to happen they both have to betray their first love. I'm not going to tell anyone else they shouldn't like Marichat, but leave me out of it. If you can't find the fanfiction you want to read, write it yourself.

Here's a relatively more light hearted one before we get back into the darker ones. This time they're already dating at the start.

"Scene five from the top."

History day was next week. Their school was participating in a fictionalized account of a battle that was believed to have occurred four hundred years ago on the very grounds where their school now stood. There was nothing romantic in the history books, but as with most theatrical productions, creative liberties had been taken to spice things up. The wives of four of the soldiers were on stage now, pleading with their husbands to return to them alive. Marinette was up there, running her fingers over her husband's stubbled chin, telling him how she loved him. Her other hand rested protectively on her swollen abdomen.

Below the stage, Adrien couldn't take his eyes off Marinette. In the context of the play, she was married to that boy from the school across town, and the baby she was proudly carrying was his. In reality, she was Adrien's girlfriend, and her pregnant belly was plastic, strapped to her flat stomach underneath her costume. Adrien was surprised how good it looked on her. With her 1600's era clothing, along with the baby bump, she was no longer as cute as Adrien was used to describing her, but no less captivating in his eyes. She looked like a woman, an attractive woman.

The stage director warned Adrien he needed to pay attention, his scene was going to be up next. That wasn't much of a problem, with Marinette out of sight back stage, Adrien was able to pull of his part without much trouble. Like that, the first dress rehearsal was done.

"What do you think, Adrien, do you like it?" When Marinette came out of the girl's changing room, she hadn't taken off the prop belly. Instead, she'd put her own shirt on over the top of it. It was worse, not only because modern clothes accentuated the belly more, but because it showed him what Marinette would look like pregnant rather than her character. She was hot. He never thought of his girlfriend as hot, she was cute, adorable, and pretty, but hot had been reserved for her alter ego, until now.

"Wha-what are you doing?" he asked her.

"I saw you staring the whole time I was up on stage, I wanted to know if you liked it on the regular me as well."

"Take it off," Adrien begged her, his cheeks flushing, "I'm not comfortable with this."

"All right." Marinette reached up the back of her shirt and undid the straps, letting the fake belly fall out of her shirt. "Better?"

"Much," Adrien sighed in relief. "Not that you didn't look good, it looked too good, and I can't risk seeing you like that until - not for several more years at least."

Marinette smirked, she felt powerful. Her boyfriend always treated her as little and cute, or as something delicate he was afraid he would break. She always felt loved, but rarely in her civilian did she recieve the awe that Chat gave Ladybug. It might be fun to see how far she could push him.

That evening, Ladybug knocked on Adrien's window. He hadn't expected to see her again today, but he went to let her in anyway. "Close your eyes," she told him. Adrien did as he was told. "Spots off," he heard his girlfriend release her transformation. "Now open your eyes."

At that point, Adrien got scared. Marinette had proven herself to be in a teasing mood today, but he was curious, so he cracked his eyes open. Marinette had on an even larger belly than earlier, this one looking like it had to be full term. "Why do you have that?" he asked her. "You know none of the props are supposed to be taken out of the theater."

"Oh, relax. No one else is using it, and I'll have it back in the prop room before opening night." She arched her back against his bedroom wall, closed her eyes, and rubbed slow circles over her protruding belly. "Mmm," she moaned, "look what you've done to me."

"Stop it, please!" Adrien pleaded, his face burning. Marinette seemed to be intent on playing a game of 'how much can I turn on my boyfriend while fully clothed' and she was beating her own high score with every move.

"Why?" she asked "I know you like it."

"Which is exactly the problem! It makes me want to wnge you and fhfh dgejhk rhfj," he mumbled incoherently.

"Oh, Adrien," Marinette came over and sat on his bed next to him. "You know I love you, and whatever you said you want to do is fine with me."

When Adrien had the courage to look at her again, his eyes were burning. "Stop playing, get out of my room right now or your real belly is going to look like the fake one."

"Is that a threat or a promise?"

Adrien had had enough, if his girlfriend didn't actually want a womb full of his seed, she'd have to beg him to get off of her some time before he was thorough. With her help he got her pants off her, but left her shirt in place, no point in spoiling the effect. He lay her flat on his bed and tried to mount her, but that same belly that was so alluring to him kept him at a distance were he couldn't properly do his thing. Before he could ask her to, Marinette flipped onto her hands and knees and offered herself to be mounted from behind. In that position, he could move his hands around to the front of her as he pounded, petting her belly full with child. At times her belly felt noticeably fake, but the sensation was wonderful if he didn't think too hard. At one point he imagined he could even feel the baby squirm. He'd gotten his sneak preview into what it would be like to satisfy each other when she was pregnant with his baby for real. "Last chance," he whispered as his balls tightened. "Do you want me to get off?"

"What point is there," Marinette moaned, "to pull out of a girl who's already pregnant?"

If she insisted on playing to the end, so did he. Aware it might not be the most responsible thing he'd ever done, Adrien simply didn't have the willpower to deny himself the ultimate pleasure while his girl was egging him on. As the waves of his orgasm subsided it occurred to him, she may have been planning something of the sort for awhile and had time to sufficiently prepare herself. "Did you go on birth control without telling me?" he asked.

Marinette giggled, "I'm not telling you, one way or the other, it's more fun to see you squirm."

Within weeks they had the test results, Marinette was pregnant. If she'd gone on birth control, it wasn't very good stuff, but Adrien was of the mind to think there hadn't been any to begin with. She'd been testing him, he decided. Seeing if he loved her enough to willingly trap himself together with her for life. He did.
