Sierra's POV

"I swallowed my step-dad's MONSTER COCK in my wet tight pussy {Girth 6.5 inches, Length 11 inches, Width 2.0 inches}"

It was a whole thing when free use went into effect, because it affected my family directly. Our house and property line fell in a free use zone, and it's all that the news had been talking about for weeks.

"I hope you're ready, Sierra. You're gonna find out first hand what a pervert I am." he said, speaking confidently and laughing about it right in front of my mother. She wasn't the type to disagree with him publicly, but I knew that she hated free use. I think it just bothered her seeing the way he started looking at me.

Truth be told, I was extremely turned on by the idea of Conor having free use of me. I'd only had sex with one guy, my ex-boyfriend Jim. He had a really small penis, and he could never last long enough so that I could actually cum. I still enjoyed the sex, because I really liked him, but I knew I was missing out on what sex could really be like.

I was sitting on the couch watching TV once, and I heard Conor yelling my name from the bathroom. He told me to bring him a towel, and when I handed it to him, I accidentally saw his cock. Looking back, I'm fairly certain that he did it on purpose, and that he'd masturbated just before, because it was huge and swollen.

"I'm sorry." I said, covering my eyes and high tailing it out of there. It was so embarrassing, and I'll never forget how hard my heart was pounding when I went into my room. I couldn't unsee it, and I found myself thinking about it whenever I got aroused. After seeing Jim, and then Conor, I was very impressed with what he was packing down there.

It was more than curiosity about his big dick, Conor was muscular, and tall, and masculine almost to a fault. He said whatever was on his mind, rarely lost his cool, and was always in charge of everything. Being his stepdaughter made me feel safe, and secure in such crazy and turbulent times.

Guys my age were so wishy-washy, and immature. Conor knew what needed to be done, and had no problem doing it. No one worked harder, and that included in the weight room. We'd had a bench press, squat rack, and olympic barbells and dumbbells in the garage for as long back as I could remember, and it seemed like he never missed a day.

Living in close quarters made it almost impossible for me to not develop something of a crush on him. All of my friends talked about how hot he was, and even after all their years of marriage, my mother was still madly in love with him.

As free use day approached, my mother sat me down, alone, and gave me a straightforward talk about what to expect. I felt very awkward talking to her about it, but I understood why she wanted to bring it up.

Mom said that she was okay with it, and that it's the way that things were going to be. She told me that he was always horny in the mornings, and before bed, but that having a new lover might trigger a spike in his libido.

"He's really been noticing you lately. He goes on and on about how pretty your feet are, and how he can't wait to see your boobs." she said, blushing slightly as she relayed the information. Hearing her say that gave me butterflies in my stomach. Conor wasn't the type to shower people with compliments, and it felt nice hearing that from him.

"Really? My feet?" I asked, feeling self conscious. I hadn't even considered that guys might be into that.

"Yeah, he's kind of a foot guy. He likes sucking on toes, so be ready." she said, grinning.

"Alright." I said, laughing nervously and wishing that we could move on.

"I just didn't want you to feel bad about this. I'm okay with it, I just want you to have fun, and make the most out of the EQ weopportunity to deepen your bond." she said.

"I will, mom. I just don't want to disappoint him, I've only had sex a handful of times." I said, surprising myself by opening up.

"Oh, sweetheart." she said, brushing a strand of my hair out of my face and looking into my eyes. "You're young, healthy, and beautiful. I promise you that he's going to enjoy you."

"Thanks, mom. I hope so." I said. That conversation took place on a Friday, the day before "Free Use Day", as Conor had taken to calling it. That's all that I could think about all night, and it kept me awake, tossing and turning, masturbating several times as my mind explored the possibilities of what might happen in our free use household.

I usually slept in until eight thirty or so on Saturdays, and then went to the couch to watch cartoons with Conor.

Chapter – 0002

Conor

I always wake up before the girls, but I woke up extra early out of pure excitement for free use. It felt completely surreal, suddenly having the privilege of my beautiful stepdaughter Sierra.

It was a different level of energy than I was used to waking up with, and I couldn't help smiling as I prepared my coffee, and downed a couple of egg whites. My dick was half hard just thinking about it, and I still had morning testosterone flowing through me.

Sierra would come out soon, wearing her pajamas and ready to watch cartoons like usual. It was our little tradition. Her mother joined us on occasion, maybe for a show or two, but it was more of our thing. And now that free use had arrived, I had a feeling our little ritual was about to get a whole lot more intimate and intense.

My senses were heightened because of the anticipation, and I could hear Sierra bustling around in her room. She'd be out soon, and I was immediately at full attention. I was free balling it in a pair of gray sweatpants, and I stood up from the couch to try and walk it off.

I was refilling my coffee when I heard her dainty footsteps, trotting down the hall towards the living room.

"Hey sweetheart." I said, walking in behind her and taking a look at her juicy little ass in a cheeky pair of booty shorts.

"Hi, daddy." she said, smiling and turning to face me. Her hair was a mess, and I could see her erect nipples pressing up against her white t-shirt as I wrapped her up in a morning hug. My hands moved instinctively lower than usual, past her lower back until my fingers were sinking into the soft flesh of her ass.

"You know it's free use day, right?" I asked, as she looked up at me smiling. She bit her lip, nodding her head.

"Yeah." she said, giggling softly. I could tell she was nervous, but the friction between us was so nice. I pulled her hips to mine, walking her to the back of the couch and pinning her, slowly grinding against her.

"You're so pretty." I whispered, brushing her hair out of her face.

"I look terrible, daddy." she said, her eyes wide as my hands moved up her torso, fondling her breasts.

"No you don't. You're such a natural beauty." I said, nestling my nose against her neck and placing soft kisses behind her ear. Her body language relaxed, and she looked into my eyes.

"You're so sweet." she said, her doe eyes drawing me closer until my lips were on hers. I lifted her up onto the back of the couch, holding her by the waist as we kissed with lust for the first time. I'd given her quick pecks before, and they always left me wanting. "Mmmm...."

"I love your lips, Sierra." I said, sucking on her bottom lip and slipping my tongue into her mouth. It was so hot that I was seeing stars, and my cock was so hard that it had a pulse. I didn't even know I was still capable of getting that aroused so easily. We broke our kiss, and Sierra slowly opened her eyes.

"That was nice." she said, practically a whisper.

"It was. I can get used to kissing you."

"Me too." she said, fighting a smile.

"Not just on your lips. I'm going to kiss you all over, baby." I said, whispering directly into her ear and lifting her up into my arms.

"Anything you say, daddy." she said, wrapping her legs around my waist as I carried her to the couch, plopping her down in front of me. Every fiber of my being wanted to rip off her clothes right there, and passionately make love to her without shame. But I knew she was nervous, and inexperienced, so I forced myself to slow down a little and turned on the television.

"What do you wanna watch?"

"I don't care, daddy. I just wanna be with you." she said, cuddling up to me. We weren't normally that affectionate during Saturday cartoons, but she seemed to be craving touch the same way I was.

"You're too cute, you know that? It's not fair." I said, wrapping her up in my arms and kissing the top of her head.

"Life isn't fair." she said, smirking.

"You're right." I said, taking her hand in mine and guiding it to my crotch while continuing to change the channels.

"So naughty." she said, wrapping her fingers around it and stroking it over my sweatpants.

"He just wants you to play with him." I said, exploding with pleasure as her little hand explored.

"He's really big." she said, lighting up and staring at my bulge.

"Do you wanna meet him?" I asked, completely losing focus on the television.

"Of course." she said. Her excitement was palpable, and I was happy about how comfortable she seemed. I lifted my hips and pulled my sweatpants down to the floor, letting my cock flop out on full display. "Oh my goodness, daddy."

"Do you like it?" I asked, holding it by the base and letting her admire my erection.

"It's...so manly." she said, reaching out very slowly, like it might snap and bite her hand at any moment.

"Well, yeah. It's a penis." I said, eliciting her laughter as she grabbed hold of my dick.

"Oh, God. Baby. That feels so fucking good." I said, throwing my arms over the back of the couch and leaning back. It had been so many years since I'd been with a new woman, and her touch was everything I'd hoped for and more.

"I should get some lube." she said.

"You could just use your mouth." I said.

"Okay. We should watch cartoons while I play with it, and see if you can last through a whole episode." she said, full of youthful exuberance and spunk. I smiled, loving the idea.

"Such a good girl. You know how much I love you, right?" I asked, seeing her in a whole new light. She shook her head dramatically, looking right back at me.

"I love you too, daddy." she said. It's not like I didn't have high expectations for free use, but actually being in that moment made the anticipation pale in comparison to the reality.

Having full access to my Sierra was going to change my life in a major way, and I couldn't wait to go down that rabbit hole with her.

Chapter – 0003

Sierra

Conor put something on, and pulled me into his arms for another kiss. My hand moved to his cock, eagerly pulling on his hard meat as our tongues swirled together. My butterflies turned into fireworks, and words can't explain how good he made me feel just by kissing and touching me.

"Get it wet." he said, kind of pushing my head down between his legs. I could hear my pulse in my ears, and I was so turned on that all I could do was obey him. I brought my lips right up to his cockhead, and let saliva drizzle out from between my lips, spreading it gently around with my fingertips.

"Like that?"

"Just like that, baby. Good girl." he said, sighing with pleasure as I parted my lips and started sucking his mushroom head. I felt the pressure pounding in my pussy, and my inhibitions faded away as I swallowed around his flesh. "God damn, Sierra. You are so good at that."

"I like it. It's fun making you feel good." I said, making popping sounds with the head of his cock. It was so warm, and I could feel it pulsing in my hand as I squeezed around him, stroking up and down his length.

"This is going to be our regular Saturday morning thing." he said, taking deep breaths and smiling. "Don't forget my balls."

"I won't." I said, shaking my head. He'd warned me for weeks about what was coming, so it came as no surprise that he wanted more.

"Lay between my legs." he said, pulling his shirt off so that he was completely naked. That's when the reality really settled in, that things were about to go further than they ever should between a stepdad and his stepdaughter. We were in the living room for goodness sake, and we'd be the first thing my mom saw if she came down the hallway.

"They're so squishy." I said, giggling as I got into position, laying on my stomach right between his legs. Being that close to his cock further spiked my arousal, and I gave in to my deepest desires, worshiping his balls without shame, the same way I'd done in my fantasies so many times before.

"Fuck. That's so good. Look up here, show daddy those pretty eyes while you suck." he said. Staring into his eyes with a mouthful of his balls was the most intense, intimate thing I'd ever experienced. It felt so primal, and it was such a distinct shift in the dynamic of our relationship.

"Mmm...."

"I love you, Sierra. So much." he moaned, writhing beneath me and pressing my head down into his crotch, thrusting and rubbing his balls and cock all over my face.

"I love you too, daddy."

"You look so pretty with a mouthful of cock."

"Thank you. I can't help it, I love my daddy's dick." I said, drooling and grinning. It felt so naughty, like we were sneaking around and exploring sides of ourselves that weren't supposed to be acquainted. It was taboo, and it was so hot.

"Get naked, Sierra. You don't need to be wearing any clothes right now." he said, leaning up to assist in removing my shirt. He was becoming more urgent, and tugged at my waistband.

"Yes sir." I said, stripping all the way down. It felt freeing, finally being naked with Conor like I'd dreamed about, letting him gaze up and down my body.

"You're too much. I'm never going to be able to get enough of you."

"Don't worry, I'm not going anywhere." I said, taking hold of him with both hands.

"I don't know if I'm gonna make it through the whole episode. You make me want to explode." he said, watching me work it up and down, applying more saliva as needed.

"I can see that." I said, noting how swollen and puffy his cock was. It was impossibly hard, red with veins leading all the way up the sides of his shaft, spit soaked and glistening. "But I think you can make it." I said, going faster, swirling my fingers around the tip and watching him squirm. It was so sexy seeing his reaction to me, finally knowing beyond a shadow of a doubt that the attraction was deeply mutual.

"Not if you keep up like that." he said, grabbing my hands to stop me. As he pulled them away, his cock twitched like it had a pulse, jumping dramatically several times before a drop of cum dribbled out from his slit.

"Wow. Why is that so sexy?" I asked, feeling my face turn red at the sight of my step father's pulsating erection. Jim had always been clean shaven, and much smaller, making it seem so boyish in comparison to Conor's formidable cock and mane of pubic hair. The muscles had the same effect. It was truly the difference between a boy and a full grown alpha male.

I stayed in position between his legs, half watching the cartoon and slowly edging him, bringing him all the way to the brink again and again until we were finishing the second episode. His entire demeanor had changed, from easy going and horny to completely unhinged.

"Fuck, baby. I love the way you touch me. It feels so good." he said, eyes closed and grinding rhythmically against my touch. "My baby. My sweet little angel. My good girl."

"Yes, daddy. I love you so much." I said, feeling the tension and desperation in his tone and labored breathing. He was completely relaxed and under my power, savoring every second and fully locked into the moment. I'd never heard him whimper before, and I could feel the immense pressure in his fat cock as I pushed my tongue along the bottom of his shaft.

"I need to cum, Sierra. I want to cum for you."

"Of course, daddy. You can cum whenever you want." I said, loving that he was holding out for me. "How about I make you cum when the credits start to roll?"

"Now." he grunted. "Sit on it. I'm so close."

"What?"

"Get in my lap. I have to feel inside you." he said, frantic and sitting up. I was easily hoisted into the air by his powerful arms, and sat down in his lap.

"Oh. Okay." I said, soaking wet and more than ready to receive him. I just hadn't expected it to be so sudden.

"I need it, baby. I need to feel your pussy. I'm so fucking close, I can't take it anymore." he said, lining himself up with my opening and pulling me down onto him.

"Ugh!" I squealed as he split me in half, impaling me on his thickness and thrusting against me while pulling down on my hips.

"Fuck."
