I nervously twisted my fingers around each other as I sat on the edge of my bed. Mark was due to arrive any minute, and I had to figure out a way to get him inside without Nick, my stepdad, noticing. He had demanded I stay away from boys, despite me being 18. I thought it was ridiculous, and I had felt that way since I was younger. I'd been seeing Mark for a few weeks now, and he was undeniably hot. Not the smartest guy in the world, though. A lot of the time it was cute, but other times it got irritating. I wasn't expecting the man of my dreams to be brilliant, but I did want someone to be able to hold a conversation with me; Mark was a bit of a toss-up in that area. That being said, he had a toned body and a sexy face, so I figured I'd see how things went with us. Nothing too serious had happened between us yet and I was still a virgin. We'd made out and done some groping here and there, but nothing more. I'd been fantasizing about going further for a while now. It seemed like my stepdad's expectations of me had conditioned me to keep myself "pure", though it wasn't something I actively thought about - it just showed up in my behavior.

Nick had been a great stepfather to me ever since my mother passed away when I was only three. I don't remember her, but I've seen pictures and everyone always spoke highly of her. Nick dated intermittently throughout my childhood, but he was always devoted to taking care of me and advancing his business career. We had a strong bond until my teenage years approached; then, we started clashing. I wanted greater freedom and he was scared of giving it to me. I began to mature sexually at an early age and this made Nick uneasy. The thing is, he had no idea how uncomfortable he should be!

Whenever he would have a girl over - which wasn't that often - I would creep up to the bedroom if she stayed the night, then I’d press my ear against the wall and masturbate while listening to them fucking. My stepdad was an incredibly attractive man, tall and muscular with ebony skin and piercing eyes that burrowed into my soul. Unfortunately, it was not feasible to act out my dreams of sexual relations with him. Instead, I had to turn my attention to Mark. A simple boy who could provide me whatever I wanted, only for me to throw away as soon as I was through with him. And so I waited for his call, waiting to haul him into my bedroom in secret.

I fidgeted with the phone in my hands, scrolling through the “apps” screen nervously back and forth, until finally the screen changed.

Incoming call from “Mark ”.

I tapped ‘answer’ and snapped the phone up to my ear. “Are you here?” I whispered.

“Yeah babe, I’m right at the front door,” he boomed in reply Idiot! I thought.

“Shut up!” I hissed. “My dad could hear you! If he does, he’ll kill you, then me, then himself!” I continued.

“Oh, sorry babe,” he said, his volume lowering with each word in a stepwise manner.

“Come up to my window, I left one of my dad’s ladders nearby, it reaches my window,” I whispered with a braggart’s tone. I felt so clever for sneaking it out when he was at work and propping it up there. Nobody ever really went around that side of the house unless they were doing lawn work or some kind of home improvement project. No one was doing anything of the sort.

I didn’t want to hear Mark keep talking, I just wanted him to climb into my bedroom and fuck me and get out. Yeah, that sounds bad. Maybe even a little cruel, given that I know Mark has feelings for me. I couldn’t help it, though. I had sexual needs, and it was easy to fulfill them as long as I dressed provocatively and flirted with cute guys. I didn’t have any feelings for Mark at all, other than feeling bad about that fact.

The only person I’ve ever had truly romantic feelings toward was, well, Nick. Yeah, my stepdad. I know it sounds gross, but there wasn’t anything I could do about it. He was hot, he took care of me, he had a sexy dominant attitude and I felt a special connection with him. That was frustrating because I knew it could never be reciprocated, so I filled that void with flings with nice, hot, well-meaning guys like Mark. Good old Mark. I could hear him slowly ascending the ladder, making sure not to step too loud or to fall off.

God I hoped he wouldn’t fall off.

For a laugh, I left my window closed. The one that the ladder went to, that is. I left it locked too. My desire to see him confusedly try to open the window and look at me with his puppy-dog eyes overwhelmed my desire to get him safely and quickly into my bedroom. It was just too good to pass up.

It went just as I suspected. He reached the window, and then smiled at me. I smiled back, and then gestured for him to open the window from my bedroom. I was wearing a low cut top and extra short shorts as I lay on my bed. When he first pulled on the window, it naturally didn’t budge. I spread my legs and started to rub my pussy through the fabric of my shorts in front of him as he began to panic, tugging and yanking at the window handle like an enraged animal. After a few moments, it stopped being funny and started being sad, so I burst out laughing and darted over to open the window lock for him.

“What the hell, why didn’t you open the window, Amy?” Mark asked in a frustrated (but not angry) voice as he finished crawling into the bedroom, letting out a light thud as his ripped body hit the pink carpet.

“I’m sorry baby, I was just messing around,” I replied and batted my eyelashes. To complete the effect, I put my elbows together in front of him, pushing my tits together and exposing my cleavage to him.

He let out a satisfied noise and reached to grab my breasts, which I let him. I let out a soft moan as he fondled me. He leaned in to kiss me and his lips met mine. Mark let out a different sort of satisfied noise, and I realized that he was licking my lip gloss off of his own lips. It was watermelon flavored, and I put it on because that was his favorite flavor. But obviously I didn’t expect him to just… fucking eat it while we were supposed to be making out.

“Ah-hem,” I not-so-subtly grunted.

“Oh, it tastes like watermelon,” he said with a smile. “That’s my fav—” “I know Mark, that’s why I bought it,” I said with a disappointed giggle. I then leaned in and started to kiss him again, taking control of the situation he was a little bit too slow to recognize. His tongue quickly entered my mouth and we began to French kiss as he pushed me onto the bed. I fell down on my back and rubbed my hands up his thick, strong arms. His body was much more attractive than his mind, and so I wanted to distract him from talking or thinking too much.

Our make out session continued for a few minutes, and then things started to get hot and heavy. I was rubbing his cock through his jeans and he was groping my tits harder and harder. The excitement welled up in me and I reached to take my top off. Once he took a look at my impressive cleavage bursting out of my bra, he reached over to unclasp the hook immediately, effortlessly lifting my body in the air with one hand by my back while reaching behind me with the other to undo the clasp. He fidgeted with it for a moment, and then it clipped right off.

“Oh, shit!” I heard Mark say. The next few seconds were a blur.

I remember seeing Mark leap out of the window and the sound of the ladder crashing against the ground. More importantly, I remembered seeing the intense and furious look on my stepdad Nick’s face. It was like nothing I’d ever seen before.

“Come with me. Now,” he ordered in the most chilling and stern voice I’d ever heard him use. I began to stand up, and just like that, my bra fell right off of my chest, exposing my voluminous boobs and my small erect nipples to my infuriated stepfather. His jaw dropped just a little bit, and he took a slight step back. Never once did he look away from my tits though. I froze like a deer in headlights and it felt like a millennium had passed before I covered myself up with my hands. My face was burning hot and the wetness between my legs was basically a flood. He looked away, shaking his head, and I threw my top back on (braless) and left the safety of my bedroom.

I followed him with light steps as the deafening silence of our home echoed in my head. Is he going to kill me, like, literally? I thought to myself with genuine worry. I had no idea what was coming to me. He led me into the gloom of the recreation room, not bothering to flick the lights on.

“Sit down,” Nick commanded, gesturing to one of the bean bags in the room as we entered. The recreation room was where we used to spend our time playing board games and watching TV together when I was a kid. There were a lot of happy memories between us, and there was a strange sense of calm as we entered the room. Moonlight streamed in through the window, giving my stepfather an otherworldly appearance as he towered over me.

I plopped down on the bean bag and my big tits bounced freely in the air, bursting out of my shirt briefly and exposing my nipples to Nick once more. Am I doing this on purpose? I wondered to myself. I knew that I was attracted to him but I wasn’t doing any of these things on purpose, or at least not consciously on purpose, or however that works. Nonetheless, he stared at my tits again, this time just ever-so-slightly licking his lips while he did.

“I’m sorry, I can exp—”

“Shut up,” Nick interrupted with a stern tone. “What am I gonna do with you? You’ve been acting out more and more. You used to be such a good little girl, and now I catch you in the middle of the night with some dude in your bedroom!?”

“I wasn’t going to—”

“Hey! Shut!” he snapped at me like he was scolding a pet. “You’re acting more and more like a disobedient little…” He hesitated for only a moment before finishing, “Slut.”

Hearing Nick call me that, strangely enough, got me insanely wet. I started to breathe heavily when he said it.

“A bratty, disobedient slut,” he sneered.

My head shot downwards again and the look of shame on my face was palpable.

“I’m sorry, Daddy.” I replied meekly.

“Sorry’s not going to cut it this time, Amy,” he said. “I’ve run out of options with you. There’s simply no punishment that will stick. So I’m going to have to do something more extreme.” Another deafening silence enveloped the room as I waited to hear what sort of awful punishment I was in for this time. Grounded for a year? Take away my car? Move me away to another school? The silence continued for about a minute straight.

“Take your top off,” a stern order shot through the rec room. My head shot back up and looked him right in the eyes. A fierce, fiery storm was building in them.

“What?” I asked, massively confused.

“Take that top off. If you’re going to behave like a slut behind my back, then I’m going to show you how sluts get treated.” My jaw dropped. I gushed between my legs. I probably turned the color of an apple, and started squirming nervously.
