Penelopes POV

It was a long day at the BAU. The team was back from their latest case. I was finishing up on some paperwork when my phone rang.

"Garcia." I said answering the phone

"Ms. Garcia, I was wondering if you could help us out with a few things on our case." I heard the leader of Team B say.

"Oh, of course. Im always glad to help." I responded as they sent me the files to look over.

After i hung up, there was a knock at my door.

"Enter if you dare." I said.

"Baby, you bout ready to go home?" I heard Derek asked.

Derek and I have been dating for a few months. I practically lived with him.

"Oh shoot. Im gonna be here for a little while longer. I have to help Team B real quick." I told him, turning in my chair.

"Oh. How long will it be?" He asked.

"Maybe 3ish hours. You can head home now and when im finished here, ill just call an Uber." I replied.

"Are you sure?"

"Yes hun. Im sure." I reassured him and he leaned in for a kiss. He left and then closed the door behind him.

I began to work on the files they sent me.

A few hours later, I was finally finished. I glanced at the clock and it read 11:10pm

I quickly shut my computers off and grabbed my belongings.

I ordered an Uber and waited.

I finally arrived at Dereks house and almost all the lights were shut off. I used my house key and entered the front door. I walked in the kitchen and sat my things on the counter. Thats when I noticed the two wine glasses on the island counter.

I frowned but thought nothing of it.

"Derek?" I shouted. No answer

I kicked off my heels and began to walk up the stair case. I figured he was already asleep.

"Derek?" I said again. Still no answer. Thats when I heard it.

"Oh shit baby. Thats the spot. Oh fuck. Im cummmminnnggg!" I heard her squeal and a headboard hitting the wall.

I couldnt believe this. I stopped in my tracks and covered my mouth. Tears springing to my eyes. I froze. I couldnt move. I wanted to barge in and see what the fuck was happening but I couldnt. My feet stayed planted.

"Ohhhh FUCK YES! Baby boy. Its so fucking deep.Uggghhhh shiiitttt. Its in my guts. Holy shit." The girl moaned again. All I heard were screams and skin slapping.

I sat on the top stair and begin to think. Think about what might my next move be. Thats when I heard it.

"Oooo yes fuck me. My pussy is so much tighter than your girlfriends. isnt it?"

"Ah fuck yes. So much tighter. Shit. Im bout to bust." He groaned. I cried harder when I heard Dereks voice.

"Yes baby. Please give it to me. Put your black baby inside of my womb plllleeeaassseee. Ohhh fuck. Im squirting!"

Thats when I lost it. My sadness turned into anger. I stood up. Brushed myself off and went to the door. I turned the knob and it swung open.

"What the fuck?" I screamed as I seen the strange girl in doggy style with Derek pounding her from behind.

"PENELOPE!" He screamed, pulling out.

"What is this?" I said with tears running down my face.

"I-its not what it looks like." I heard him say as I started to gather my things.

The girl got dressed and ran out the door.

I kept quiet as I began to gather my clothes. my trinkets. and my toothbrush.

"Wait. Baby. Please dont leave." Derek begged.

"How long has this been going on. With her?" I asked with hatred in my voice.

"It was an accident. Please baby girl. Lets talk this out." He said grabbing my hand

"NO. You dont get to do that Derek. You dont get to come here, and have sex with a random girl when you're in a committed relationship with me and then touch me."

He tried to grab me again.

"DONT FUCKING TOUCH ME!" I screamed.

"Pen please. I'm sorry."

"No. I'm done." I told him and i grabbed my things and ran downstairs.

"Please. Penelope. Just give me another chance. I'll do anything." He begged.

I ignored his pleas. I grabbed my keys and my phone off of the counter and ran out to my car. I started it up and drove to the first place I thought of. JJ's.

I got out and went to the front door. Knocked and waited.

"Penel- Whats wrong?" She asked wiping the tears from my face.

"D-Derek. He cheated on me." I responded.

"Oh honey. Come in." She led me in and sat me on the couch.

"How do you know he cheated?" She asked.

"I came home from work and they were in our bed." I told her.

"Im so sorry." She said rubbing my back.

"H-how could this happen? I thought we were happy."

"I dont know. We'll find out." JJ said.

"Not tonight. Please. I cant do this tonight."

"I understand. We'll figure this out tomorrow." JJ said.
