Cheating with my boyfriend's best friend novel (Olivia and Aaron)

I had to break up with him.

The thought echoed in my mind repeatedly.

If I broke up with him, all of my problems would be solved.

Why didn’t I just do it?

This whole time, I’d been obsessed with my childish revenge plan. I wanted to make Vincent regret betraying me. I wanted him to pay the price.

So what did I do? I slept with Aaron, his best friend.

And what did I get out of it? A messy relationship that’s ruined my progress at work. An unparalleled sexual experience… God, I never thought sex could be such a beautiful thing…

Stop!

I blushed and forced those thoughts out of my head.

Regardless, the truth was that it wasn’t good for me to stay with Vincent any longer. I’d rather learn from Nick and spend my time doing something meaningful than waste it on a scumbag like that.

I thought it’d be a good idea to break up with him on Christmas Day, as a present to myself.

I’m sure it’d be memorable for Vincent.

As for Aaron…

I honestly didn’t know how to handle my relationship with him. I couldn’t even concentrate on my experiments lately with him in my mind. It was holding back my efficiency, but when I thought about ending things with him, I couldn’t do it. In the end, he was just my fuck buddy, so nothing real could develop between us… But he always did things that made me think he liked me.

At the end of the day, only he knew how he felt about me. I didn’t want to dwell on it, so I decided to listen to my heart and live in the moment.

With my mind made up, I let out a long breath and felt my whole body relax.

Then Vincent called me.

“Vincent? I actually needed to talk to you…”

“Hey, babe. Wanna go out with me tonight?”

The moment the call connected, I heard a woman’s voice coming from the other side. Even though it was brief, I knew it was Emily.

I frowned. Even though I already made up my mind to break up with him, it still made me angry to know he was carelessly messing around with other women. I couldn’t figure out what he was trying to do. If he was with Emily, why was he calling me?

“Where?” I pretended I didn’t hear her.

Vincent sounded relieved. “Do you have time tonight? My friend’s throwing an early Christmas get–together before we

see our families. Did you wanna come?”

I raised my eyebrows. Emily was right next to him, yet he called me to invite me to the party. Did he think I wouldn’t want to go?

It was true though. I didn’t want to. Vincent’s friends always found all kinds of excuses to get together and drink. All they did was play games and talk about women, which wasn’t interesting to me.

But I knew that Vincent was counting on me not going so that he could take Emily, and I wasn’t going to let him get away with it.

I tried to sound interested. “Who else is going?”

“Uh… Everyone…” As soon as he said that, I heard a sharp slap. Emily must’ve hit him for saying that.

I snorted. “If everyone’s going, then I don’t wanna be left out. Come pick me up.”

The line went silent for a few seconds, and I asked in mock confusion, “What’s wrong? Would that be inconvenient? You didn’t want to take someone else, did you…?”

“Of course not!” Vincent hastily denied it. “Just wait there, babe. I’m coming.”

“Don’t make me wait too long!” I hung up, satisfied knowing that Emily would be miserable at the party.

I stood in front of my closet picking an outfit. Once upon a time, I would’ve chosen a relatively conservative dress, but today was a special day.

Not only did I have to outdo Emily, but I had to officially break up with Vincent. On top of that, I would finally sort things out with Aaron.

I decided to honor my heart and enjoy myself before having a lonely Christmas.

My eyes scanned the many dresses in my closet before they finally landed on a tight black dress. The same one I bought with Aaron’s card.

I didn’t know if Aaron was going to be there tonight, but Vincent said everyone would be there. That had to include him, right?

Aaron was the real neuroscientist in our relationship. Even though we hadn’t talked in a while, I couldn’t help but think about him. I even chose the dress because I knew he’d like it

best.

The dress had a low neckline, and it pushed my breasts together until it almost looked like they were going to pop out. The material wrapped so tightly around my ass that it made it difficult to walk. But when I saw myself in the mirror, I

felt like it was worth it.

I put on stockings, 8 centimeter red heels, and bright lipstick.

Now I was ready for battle.

Snow began to fall past my window as I picked up a diamond ring from the jewelry box. I put it on as solemnly as a knight armed himself with his sword.

The Cartier ring was from Aaron. It had shown up on my desk

the day after he threw away the engagement ring Vincent gave me. The funny thing was that Vincent never found out about it.

I looked at myself in the mirror.

My dress, jacket, and ring were all from Aaron. If anything, I felt like his fiance…

God, what was I thinking?!

I lightly slapped my face a few times to snap myself out of it, and then I slipped on my heels. Just as I reached the door, I turned back, remembering something else Aaron got me.

I stared at my blushing face in the mirror, took a deep breath, and mustered up the courage to pull a plastic bag out of the bottom of my closet. I reached in and hooked my fingers into the black cut–out thong that Aaron bought me, but I couldn’t bring myself to look at it.

“You’re such a slut…” I muttered to myself, but I still pulled on the lacy thong with shaking hands.

Then I dialed Vincent.

“I’m ready.”
