Chapter 1: Revelation
*Him:*
I want to say that it started like any other day, but the thing is it wasn't any other day heck it was the most confusing day I ever had. You know how you know that something is bad for you but can't stop thinking about it, that you shouldn't pursue it but, unconsciously you still do, well that was me when I fell in love with my sister.
I'm Jason I'm 27 years old. I work for a good company, decent salary, I wouldn't say I have a good body it's one of those kinds that's a cross between a buff dude and dad belly person. Black hair 5'10. As for my sister, I let her do the honors of introducing herself.
Anyhow, It was late Friday evening. I was bored, a co-worker sent a link, going on it I found out it was a story based on true events about two siblings that fell in love.
Reading through the story turned me on bad. The scenes were so well written and conversations had my mind in a place where I could actually hear as they spoke and how they spoke. This occurrence only happens when you are deeply invested in something which tells u how much I was into it.
Somewhere along the line, I started imagining myself in the main lead's shoes. So when that happened my mind automatically adjusted my sister to the main female lead. As their love grew so did their passion, which made for an even amazing read.
So back to Friday night, there came a scene when the female lead is bending forward on the kitchen counter and her brother is taking her from behind while their parents watch TV in the next room, the angle such that if their parents look back they would see their son pounding their young daughter to the hell and back. He had his hand covering her mouth from moaning and howling. He senses she's close so he puts his mouth on hers kissing her full on the lips all the while, taking her nipples in hands and slowly rolling in opposite directions. Rolling them far enough for it to be twisting making her moan in his mouth.
As he does so, her eyes roll back in her head and she starts shaking hard as the mother of orgasms hit her hard fueled by the fact that it's her brother fucking her, that it's her brother that's pounding her from behind like a bitch in heat, that it's her brother fucking her like that when her parents are in the next room.
She squirts for all her worth finally moaning one last time in his mouth before saying "I want you to knock me up big brother, put your seed in me, breed me for your pleasure". Hearing those words was enough to send him over the edge and he starts ramming in her even as she comes down from her high. Grabbing her hips and balls deep he empties his seed deep in her falling on her back spent panting hard but trying to keep his voice down.
I kept reading and reading which made a huge tent in shorts covered by a sheet. So engrossed I was in the book that I didn't notice my bulge through the sheets. Finally, when I couldn't hold it any longer, I got up, leaving my cell on the bed and went to the bathroom to masturbate.
I came back found my sister staring at me funny. I sat back on the bed and finally asked her "what?!?"
