Obviously, this is aged up. This is an AU where Adrien never went to public school or fell in love with Ladybug. Has married Chloenette in here and hinted NSFW.

It was a hot summer's night in Paris.

Chat Noir bounded across the rooftops, on the lookout for criminals. Since the defeat of Hawkmoth by his and the mysterious Ladybug's hand, crime had gone down. But college had made sure he hadn't slept in a week.

He landed on the sidewalk, starting to walk.

A small cough made him turn.

A young woman stood behind him, black hair pulled into pigtails. She was dressed in a neat blouse and pants, a blazer over it. Her blue eyes were filled with tears.

She was beautiful.

"Um, hello."

"I heard you were a man of honor." She said, stepping forward. Chat could see the slap mark on her face. "I'm so sorry, but I need help."

"What's wrong?"

He carefully led her to sit down on a nearby bench. She sniffled. "M- My name is Marinette Bourgeois."

Ah, the Mayor's daughter in law.

"My wife, Chloe, s-she abuses me and I know she's sleeping around. A-And I don't know what to do."

She burst into tears, looking utterly helpless.

"I can talk to the police." Chat said. "I can take you home."

Marinette sniffed and looked up with a smile.

"Thank you."

-_-

He landed on Marinette's balcony, setting her down with a smile. "Here we are Princess."

"Thank you."

"I should be heading back..."

Her hand around his made him look down. She was blushing. Opening the door, Marinette led him through the penthouse.

Opening the door, the bedroom was revealed.

"Stay." Marinette said, spreading her legs. Chat blushed, watching her unbutton her top. Black lace hid her breasts from him.

He should say no to this.

But she looked so helpless, and her body screamed 'Hell yes.'

He was broken from his thoughts by her mouth on his.

And he gave in.

Her clothes scattered the floor, his own suit disappearing. Only the mask was left.

The two practiced foreplay, stroking and touching each other as they kissed. Soon, Chat was entering her, loose haired Marinette screaming his name as he fucked her.

Several rounds later, they fell asleep in each other's arms.

-_-

It became a pastime, visiting Marinette. He would bound onto her balcony, eating the food she offered and having sex.

He was in love with her.

A month after the first night, he received an email.

Dear Chat Noir,

I hope this email finds you well and wealthy. See, I have found out the relationship between you and my wife. But, you can keep seeing her...

If the price is right.

Chloe Bourgeois

-_-

He entered with a "How could you!"

Marinette turned, a bathrobe draped over her body. "What?"

"The email! Was this a set up?"

"What email?" She said, tears forming in her eyes.

"The one from your wife!"

She held onto him. "Please don't leave me! I love you!"

Chat's anger disappeared. Taking her into his arms, he sighed. "I love you too. And I promise, you're getting out of this marriage." He pulled her into a kiss, Marinette eagerly responding.

A cough broke them.

Chloe Bourgeois stood in the doorway. "So?"

Chat and Marinette exchanged looks.

"Nobody needs to know."
