I didn't like the taboo feelings that had come over me since I'd seen my step sister at that party. I didn't often go to those things even though I was frequently invited. I didn't know she'd started to be asked to come. She was only a freshman after all.
I couldn't deny she'd grown up in all the ways that would make her popular at those get togethers. She'd grown a couple inches, and her hair was long and silky and not awkwardly choppy. Her ass had nearly tripled in size as had her breasts. It made my pants feel tight and weird when I had first noticed how plump her butt was now.
The anger and strangeness hadn't truly awoken until that party though. She was surrounded by men much older than her. She was smirking and rubbing her fat ass all over their crotches once the music started.
I felt a whirl wind of emotions filling me at that point. I was angry but I didn't know why. I was never one to police a woman's sexuality, but I was livid in this moment. I also felt very guilty that I felt that way.
When I went to rip her off them and lecture her, she looked shocked. I knew this was out of character. I dragged her away regardless. It wasn't until later that I realised how rock hard I was.
"You're such a weirdo just standing in the fucking kitchen," she said, breaking me out of my daze. I nearly jumped.
"What are you-" I couldn't finish my sentence. I took a good look at my step sister and it was wrong what I felt.
She wore a pink jogging bra and shorts that hugged her ass perfectly. Rivulets of sweat ran down her cleavage. Her gorgeous young cheeks were red from exertion.
I felt my pants tighten and it made my cheeks redden as well. I was white knuckling the counter as she grabbed a water bottle and gulped it down. Her supple pink lips rounded perfectly around the tip. I gulped in tandem with her.
"What are you staring at?" She asked. "Trying to think of more ways to ruin my life."
I needed to ruin something.
"I didn't do anything wrong. You shouldn't be slutting yourself out, especially to boys like that."
"Awww," she said in a fake sympathy. "Is someone jealous he's not as popular as his little step sister?"
Something electric thrilled through me at those last words. She was sauntering towards me. A manicured hand splayed on my chest.
"What are you doing?" I growled.
"Your heart is hammering, the green eyed monster got ya anxious?" She asked me with her head quirked to the side.
My eyes were glued to a drop of perspiration that rolled slowly down her neck. I wanted to lap it up. I wanted to taste the flesh. I wanted to -
This was my step sister. My younger step sister.
"What do you mean about boys like that anyway?" She asked me with an eye roll.
"Well they're only after certain things," I explained.
"And you aren't? You don't like nice big ass and huge tits?" She asked. "I know your mom did raise you to be judgemental."
At the mention of my mother I gulped. I was close to panting as our eyes locked. Did she know what she was fucking doing to me?
"They don't know how to please you. They're just boys. They don't know you," I explained slowly, my voice low and dark.
