A Mistress To My StepDaddy

(Isabelle Pov)

(Flashback 4 daysAgo)

I arrived at my boyfriend's house.

While I sat in the vehicle, I had a bottle of wine in my palm, I was smiling to myself for a reason I hadn't even realised yet. Mark hadn't a clue I was coming. It had been three hours since he sent a message of him having a long day at the office and I, on a whim, had decided to do a surprise visit.

I brought wine and of course his favourite food from the restaurant had already been ordered and to crown it all the two of us would spend the whole Friday evening having a good time.

That was the part that made me so happy.

I took my purse, placed the bottle of wine inside my coat, and headed for the door.

On reaching his doorstep. Then I saw them... two pairs of slippers, which obviously looks like that of a woman. A strapped chunky heel is placed neatly on the floor right in front of Mark's door.

I froze. I looked at them.

"Could this be the neighbours?" I looked left and right. The corridor was completely empty. No one came into sight and there was no explanation who could have put those sandals anywhere other than inside that apartment.

I felt a knot in my stomach, 'Let this be not what I'm thinking'.

And to make it even more unbelievable, I recognised those sandals.

I reached for the door. It wasn't shut either. 'Fuck, what is happening?'

I pushed it open. There were two glasses on the little table. His coat was left on the armchair. The whole room was a bit dark, cozy, and the air was perfumed with the scent of a lady's cologne that made me feel a bit off.

Then... Suddenly, I heard it... a sound... coming from the bedroom.

It was a voice.

A woman's voice, and breathless at that.

My bag fell down.

I didn't knock nor did I hesitate. I rushed towards the room, my heart thumping and my feet shivering in fury, and pushed it open, revealing a scene that shattered my entire being instantly.

I saw them.

I saw Mark, my boyfriend and Chloe, my best friend, having the most forbidden sex of all time.

Naked and shameless on my boyfriend's bed. They didn't even notice I entered, lost in sinful pleasure.

I felt my legs couldn't carry me. The silence that came after was the most deafening thing I had ever experienced.

Maaarkkk! I screamed in agony.

"Isabelle" Mark hurriedly got up from the bed, a bunch of sheets still clinging to him, uttering my name as if it was already something he was trying to die from. "Shit! Dios mo Isabelle."

I looked at him with my mouth wide open, tears welling up my eyes. "What is this?"

"Isabelle, let me explain"

"What is this Mark? You are fucking my best friend?"

"It's not" He went to his feet and put his hands up. "It's not what it looks like."

I chuckled a dry and bitter laugh, totally without any trace of humour.

"It's not what it looks like?" I turned to look at Chloe who had found the sheets to cover her nakedness and was sitting there in my boyfriend's bed, covering her face in shame.

"Four months." I said slowly, glancing at Mark. "For how long has this been going on? The day I got my diploma was just three weeks back. You wept at my graduation and at the same time, you were sleeping with my best friend?"

"You're changing the facts."

"Am I changing the facts?"

"No, Isabelle, listen to me. It's really difficult"

You are my boyfriend for God sake Mark and you sleeping with my best friend is your choice and you stand and tell me I'm twisting something?"

"Look, you need to lower your voice. The neighbours might be eavesdropping."

"Don't ever tell me to lower my voice. God, Mark! You are ridiculous. You're thinking about the neighbours at a time like this? This time? Are you kidding me?"

"I just want to have a talk."

I threw my bag on the chair and faced Chloe. "And you too Chloe. I felt you are a friend I can trust."

"Oh yeah! You now share my man and his dick?"

Chloe, who felt so embarrassed and filled with shame, got up with her dress folded in her hands. "Isabelle, I understand that this is painful"

"Oh, you understand this is painful." I looked at her in disbelief. "That's quite amazing?"

"Say exactly what you mean to my face!"

Mark intervened. "Alright, let's calm down"

I turned towards him so quickly that he was forced to take a step back. "Dont you ever try to interrupt me. Don't ever stand between us as if you were the reasonable one in this room."

"See, this is exactly why I couldn't..." He stopped himself.

I looked at him and went still. "Complete the thought, " I whispered, "This is exactly why you couldn't do what, Mark?"

He covered his face with his hand.

"I didn't mean to say that"

"You almost did."

"Isabelle, stop!"

"Things between us were difficult!"

He finally raised his voice. "We were not in a good place and instead of talking about it you just you kept pretending everything was fine and I"

"Hence, you went to Chloe."

"I want you to tell me the truth! Mark, look me right in the eyes and tell me the absolute truth without trying to manipulate it!" He said nothing.

"That is what I expected, " I replied.

:

"That should be the last time I will ever ask you anything." I grabbed my bag from the chair. "We are done Mark. I want my keys tonight and everything my mom has signed under your name tonight." I stared at him.

He looked at me in fury and the bursted out. "Isabelle, you are just being too rational. Yes I did this, because I've lost interest in you. Chole satisfies me more than you do. I can't even stand or have anything to do with a woman who can't fuck me well enough."

Mark?

"Yes, do all you want. I'm done with you too." He smirked.

Tears welled up my eyes, rolling down my flushed cheeks uncontrollably. I hated to cry in front of him but now I can't hold myself anymore.

I picked up my bag and left the bedroom. He didn't even bother to go after me, console or call my name from behind. I ran past the living room sobbing profusely. They were like a regret that was so contrary to my will.

Eventually, I got to my car and entered and closed the door so forcefully that one could feel the impact even in the chest.

With both hands, I grasped the steering wheel and leaned my head upon it. For about thirty seconds, I was trembling, tearfully, and screaming in pain at the top of my voice.

At this point the only person I could call was Lena. I cleaned my tears, still sniffing, I dialled her number.

"Hello babe?"

"Hey, Bitch! What's up?

"Please I want to see you"
