"You're late," Tikki reminded Marinette.

"I know, I've just got to call home and tell them the project took longer than expected. They'll understand." Marinette started rummaging through her school bag looking for her phone. "It's not here! I must have left it in Adrien's room!"

It was a dream come true for Marinette. She had finally been given a partner assignment together with her crush. She'd been over at his house all afternoon and they'd just finished. "I'll just call Adrien and ask him - oh, right, no phone, no call."

She took a deep breath and faced the Agrestes security system outside their gate. It still managed to intimidate her, and reminded her of the time she'd dropped off Adrien's birthday present. What a disaster. She pushed the buzzer.

"Yes?" Nathalie's voice answered.

"It's Marinette! ... again ... I, uh, left room in - left my phone in Adrien's room."

The gate swung open, "come in. You can show yourself up to his room."

"Really? That was easy." Marinette was used to security around the Agreste home being restrictive, and was surprised they'd let her walk right in.

"It looks like you have clearance around here!" Tikki giggled.

"They must trust me, so I guess it's a good thing." When she thought of it that way, it made Marinette giddy. One step closer to being a part of the family!

When she made it to Adrien's door, she could hear noises coming from inside. "Gruh, uh..."

Her brain slowly interpreted the noises, then her eyes went wide. "What is he doing? Should I knock?" She was pretty sure she should probably knock, but some devious part of her brain wanted to watch what Adrien was doing. "Just a peek?" she asked herself.

She cracked the door open silently. Adrien was sitting on his bed, facing his computer, but he was clearly no longer researching for their project. What sort of images turned Adrien on? She had to know now. When she saw, she had to bite down on her own hand to keep back an exclamation. She recognized that picture...

About a week ago, she, as Ladybug, had been captured by an akuma. She'd unfortunately already used her lucky charm, so she couldn't do much to stop her transformation fading away as she waited, chained to a wall, while the akuma hunted down Chat Noir. Luckily, it was Chat who found her first, in her civilian form, chained to the wall. He'd broken her out of her bonds, giving her the chance to refuel Tikki, and return to the fight as Ladybug. She believed that no one had witnessed her detransform, but there Adrien was whacking off to two side by side images. One of her, in civilian form, chained to the wall, and perhaps more alarming, one of her half way through reverting from Ladybug to Marinette.

"Freeze! Hands above your head!"

"Marinette! What - what are you doing here?!" Adrien raised his hands above his head as he was told.

"I left my phone her by accident. So," she circled around to stand between him and his computer. "Can you tell me what exactly you find erotic about these images?" She was fully clothed in both photos, they were nothing that would be classified as porn. "The chains, perhaps? Do you like seeing a girl helpless?"

"No," Adrien shook his head. "That's not it. When I took these pictures, they weren't supposed to be anything erotic, I swear. I just couldn't believe I was getting to see who you truly were at last. I wanted to save that moment, as proof that I hadn't imagined it. But since then, I started looking at these pictures and thinking 'wow, that's my girl!' and all my feelings for you just start getting tangled into one and this happens. I'm sorry." It was then he noticed his erect penis was pointing straight at Marinette, and he tried to cover it.

"Keep your hands where they are!" she ordered him.

Adrien gasped as Marinette knelt down in front of him and took his penis into her mouth. He was already close to cuming by his own hand, and felt himself dragged right to the edge upon entering her mouth. "You're not mad at me?"

Marinette circled the tip with her tongue several times before she pulled away. Adrien's hips instinctually tried to follow, but he sat back when she glared at him. "Don't ever masturbate to a picture of me again. Save it for girls you can't have. If you're going to use me for your pleasure, I want to get something out of it too, got that?"

Adrien nodded. Marinette resumed sucking him, and this time allowed him to unload into her mouth. She opened her mouth and showed him the last of it before she swallowed. They both felt an inexplicable pride in that moment, with his seed sitting uselessly in her mouth.

"I've got to go," she told him, "be good."

Over the next couple of weeks, Adrien and Marinette shared many secretive looks when at school and around their friends, but did not explicitly mention their sexual encounter until one day Adrien pulled Marinette by the wrist into an otherwise empty hallway at school. "Help me," he breathed.

"What is it?"

"This," he guided her hand to the front of his pants, where she could feel a noticable bulge. "You've ruined me for other girls. I haven't had relief since the last time you did it for me. Normal porn doesn't do it for me anymore. I nearly came thinking of you, but I know you don't want me to."

"Good boy," Marinette was loving the power she had over Adrien. Somehow she'd snagged a boy who seemed to be physically incapable of cheating on her. "You know, I wouldn't know if you touched yourself if you didn't tattle on yourself."

"I know, but I'd rather get your help if that's an option."

"Can you hold out?" she asked him. "There's not mutch we can do here, but if I can come over later we can explore further."

"I don't think it needs to be right this minute," Adrien grinned. "We'd better plan to get some homework done while we're at it, so that my father will allow me to keep having you over."

"Finished!" Marinette got up from her seat and stretched, glad to be done with her homework for the day.

"Do you think we have time for extracurricular activities?" Adrien asked hopefully.

"That was the plan wasn't it," Marinette smirked.

"Good," Adrien got up and went over to his bookshelf. "I admit I was a little assuming, I bought these right after our first encounter." He pulled out two books and retrieved the box of condoms he'd hidden behind them.

"I wasn't planning on going that far today..."

Adrien looked disappointed, but moved to return the box to its hiding place.

"No, no, I want to! How dis you manage to get those without being caught?"

"Praise self checkout," Adrien threw a couple condoms toward his bed and reconcealed the rest of them.

Marinette felt a crippling shyness come over her, before, when she'd caught him mastrubating, lust had controlled her mind. But now, without her instincts in the driver's seat, she was uncertain how to proceed. She slipped off her shoes as a light preliminary to the disrobing that would have to occur if they were to achieve their plans.

The two of them climbed up on his bed, amd started things off with a kiss. As they became progressively more worked up, it became easier to lose their clothes without a second thought.

When they were ready for the main event, Adrien wanted to perform for his partner. He picked up one of the condom packets in his mouth and wiggled his eyebrows in a way he hoped was sexy. Marinette laughed at his show and they were both put at ease, unaware of what he'd just done. Adrien opened the packet and rolled on the condom, unaware of the puncture left by his teeth. Still trusting in the integrity of the condom, he lined himself up with her and they carefully but eagerly took each other's innocence.

"Are you close?"

Marinette shook her head, "... why are you stopping?"

"I was about to blow, if we kept going, I wouldn't be able to wait for you."

"It's okay," Marinette ran her fingers through his hair. "We're just learning. If you finish first, you can help me get there some other way."

Adrien shook his head, "I want us to finish together," he started making love to her again, much slower than before, "try to catch up."

With a great series of tremors, Adrien and Marinette shared their first climax together. With nowhere else to go, Adrien's seed wicked its way back up the shaft until it found the abrasion and life found a way.

Marinette felt the breach as soon as the stream of warm liquid hit her vaginal wall. It confused her, then her eyes flew wide as she had an epiphany. She tried to tell Adrien, but her voice wouldn't work, and her body refused to push him off of her.

When Adrien came down from his high, he realized Marinette was gasping and her eyes looked terrified. "Too intense?" he asked her. If he could make her orgasm that hard, he was proud of himself!

"The condom broke... I think."

Adrien jumped up as soon as Marinette told him her suspicion. Sure enough, the side of the condom looked like it had been blown out. "Maybe you should go to the bathroom to try and wash it out?"

Marinette stumbled to the bathroom, holding a hand to her leaking sex. Adrien followed her as far as the door, but stayed outside. He was afraid that if he joined her in the bathroom, he'd be tempted to do something that would only compound their problem. After all, he was already getting hard against just from the thought of her try to wash his seed out of her. He wondered if she'd be mad if he touched himself now. If they'd stuck to their own hands all along, they wouldn't be where they were now.

Marinette's body trembled in rebellious delight, as much as it put her mind into turmoil, it loved being bred. Marinette sighed, determining she'd got out as much of the powerful liquid as she could. Having lost touch with her sexual confidence once again, she no longer had the courage to walk out naked in front of him. "Adrien, could you please get me my clothes?"

Less than a minute later, the door cracked open and her clothes were dumped on the floor.

By the time she came out of the room, Adrien was dressed too. "Marinette, I'm sorry..." he offered her.

"Why? You didn't do anything, did you? It's just bad luck."

"Not on purpose, but, the more I think about it, I shouldn't have bit the condom. I'm sorry, that was dumb."

"Oh," Marinette gave him a sad smile, realizing he was probably right. She walked past him to the door, only pausing once she had her hand on the knob. "Adrien, I'm not mad at you, just..."

"Disappointed?" he asked.

She nodded. "I need some time away from you, okay? We'll talk about this once we've each had some time to think." Like that, she was gone.

Adrien flopped out on his bed, his kwami buzzing around his head. Plagg had just returned from wherever he's gone to avoid seeing his owner do things that would make the black cat sick.

"Plagg, do you think I'm going to be a papa?"
