My Sister Slept With Every Man I Dated, So I Introduced Her to My “New Boyfriend” Without Telling Her He Was Her Ex-Husband’s Divorce Lawyer

I posted a couple of photos on social media. Nothing over the top. Coffee dates. Dinner. A concert. The kind of mild, believable intimacy that makes relatives excited and suspicious in equal measure.

My mother called within twenty-four hours.

“Maya, you’re seeing someone new? He’s handsome. Why didn’t you tell me?”

“It’s still pretty new, Mom. I didn’t want to jinx it.”

“Well, you have to bring him to Sunday dinner this week. I insist.”

Perfect.

James picked me up at six that Sunday.

He had dressed down just enough to look approachable. Nice jeans, button-down shirt, leather jacket. Relaxed, but still clearly the kind of man Britney would immediately clock as desirable.

“You ready for this?” he asked as we pulled up to my parents’ house.

“Not really,” I said. “But let’s do it anyway.”

My mother answered the door and pulled him into a hug within seconds.

“You must be James. Maya’s told us so much about you.”

I had told him almost nothing, but that was my mother’s way.

She ushered us inside, where my father was fussing with dinner and Britney was curled on the couch with a glass of wine. She looked up, saw James, and I watched the entire thing happen in real time. The spark. The assessment. The immediate decision.

She put down her glass and stood, smoothing her dress.

“You must be the new boyfriend,” she said, holding out her hand. “I’m Britney. The baby sister.”

James shook her hand with exactly the right amount of warmth.

“Nice to meet you. Maya’s mentioned you.”

“Has she?” Britney’s eyes flicked to me and back to him. “I hope she said good things.”

“You’re very close,” James said smoothly.

I almost laughed.

Dinner was exactly as painful as I expected. Britney positioned herself where she could watch James easily. She laughed at everything he said. She touched her hair, her neck, her glass, her necklace, every movement calibrated for maximum visibility. My parents either didn’t notice or didn’t want to notice.

James played his role perfectly. He was attentive to me without overdoing it, friendly to Britney without encouraging her, and careful when she asked questions about work. He gave her enough to stay interesting, but not enough to lose control.

After dinner, my mother insisted on dessert.

Britney volunteered to help in the kitchen, which left James and me alone in the dining room for a moment.

“She’s already planning her approach,” he said quietly.

“I know.”

“Did you see the way she looked at me?”

“Hard to miss.”

He glanced toward the kitchen. “Your parents really don’t see it, do they?”

“They’ve never wanted to.”

When Britney came back with pie, she made sure to sit next to James. Her leg brushed his under the table twice in five minutes. She had freshened her lipstick and let her hair down. I excused myself to use the bathroom and left them alone on purpose.

When I came back, she was showing him something on her phone, leaning in so close their shoulders were touching.

We left around nine.

My parents stood in the doorway smiling like everything they had ever wanted for me was finally happening.

“That went well,” my mother called. “You two are so cute together.”

In the car, James let out a long breath.

“Your sister is persistent.”

“That’s one word for it.”

“She asked for my number. Said she wanted to add me to the family group chat.”

“Of course she did.”

Over the next three weeks, Britney texted James constantly.

Memes. Funny videos. Restaurant recommendations. Questions about movies. Random excuses to talk to him that had nothing to do with me, but always included some pretense of innocent convenience.

James screenshotted everything and sent it to me.

We started meeting twice a week at his office to review the messages and decide how to respond. It felt ridiculous and surgical and weirdly validating all at once.

“She’s building toward something,” James said during one of those meetings. “This is how she operates. She creates a sense of familiarity first. Makes the guy feel like he and she have this little separate connection. Then she escalates.”

“How do you know that?”

He was quiet for a moment, then reached into a desk drawer and pulled out a folder.

“During Trevor’s divorce, part of my job involved documenting Britney’s pattern of infidelity. I interviewed several of the men she had been involved with. They all described the same approach.”

He opened the folder.

Inside were transcripts, notes, photos, timelines, evidence of affairs with at least five different men during the three years of her marriage.

“Jesus,” I said softly. “Does Trevor know about all of this?”

“He knows about the ones relevant to the divorce. The court didn’t need the full archive, just enough to prove infidelity and knock out some of her asset claims.”

I looked at the folder, then at him.

“Why are you really helping me with this, James?”

He met my eyes.

“Because I watched your sister almost destroy a good man. Trevor Morrison walked into my office two years ago and he was suicidal, Maya. I’m not exaggerating. He had been systematically broken down by someone who was supposed to love him. And when I helped him fight back, your sister filed a complaint with the bar association claiming I had manufactured evidence. It was false and it went nowhere, but it took months of my life to clear it.”

“I had no idea.”

“Why would you? But that’s who your sister is. She destroys people, and then when they defend themselves, she plays the victim. So yes, I have my own reasons for wanting to help expose her.”

I studied him for a moment.

“So what’s the endgame?”

He smiled slightly.

“I was hoping you’d ask.”

The plan came together over the next few days.

My parents’ anniversary was in three weeks. Big party. Lots of family. Friends. The perfect stage. But before that, we needed Britney to feel urgency. We needed her to think she was running out of time.

So I started posting more couple photos.

Me and James at the beach. Cooking dinner. One especially cozy photo of us on his couch with the caption “Perfect Sunday.”

My mother called almost immediately.

“Maya, you two look so serious. Is this getting serious?”

“Maybe, Mom. We’ll see.”

I knew exactly where that information would go.

Sure enough, two hours later, James got a text from Britney.

Wow, you guys are moving fast. Happy for you both.

“She’s panicking,” James said when he showed me. “She feels like she’s losing control of the timeline.”

The next message came the next day.

Hey, I’m going to be downtown for a meeting Thursday. Want to grab coffee?

James replied, Sure, I have a break around two.

He didn’t tell me about the coffee until afterward. When he came to my apartment that evening, his expression was grim.

“What happened?”

“She made her move.”

He sat on my couch and rubbed the back of his neck.

“It started with small talk, then she pivoted into how she thinks I’m too good for you, how you’ve always been the unstable sister, the jealous one, and how she’s worried I don’t really know what I’m getting into.”

My stomach turned.

“She said that?”

“And then,” he said, “she put her hand on my leg and told me that if I ever wanted to talk to someone who really understands what it’s like to be in your family, she was always available.”

“Did you—”

“I smiled, said I appreciated her concern, and told her I had to get back to work.”

Then he looked at me seriously.

“Maya, she’s going to make a real move soon. Probably at the anniversary party.”

“Good,” I said. “That’s exactly what we want.”

The three weeks before the party felt endless.

Britney increased the frequency and boldness of her messages. She sent James selfies. She invited him to yoga. She “accidentally” sent him a photo that was clearly meant to be provocative and then followed it with, OMG, sorry, wrong person, how embarrassing.

James documented all of it.

The night before the party, we met one last time at his office.

“Last chance to back out,” he said.

“I’m not backing out,” I told him, then hesitated. “But I need to know something. What happens after tomorrow?”

“What do you mean?”

“I mean you’ve been pretending to be my boyfriend for almost two months. We’ve spent a lot of time together, and I need to know if this is still just revenge to you, or if…”
