Waking up that morning, I felt like I'd just gotten out of a coma. How long was I asleep? I forced my eyes to open, my head felt thick and heavy. Turning to the side, I was expecting to see Millie beside me but there was only an empty bed. Fighting my headache, I willed myself out of the marshmallow-soft bed, my feet touching the carpet of Millie's room.
As I made my way out of the bedroom to the shower, I stretched out my arms and back, hearing various muscles crackle and pop like I'd stepped on a pile of twigs and I already felt a little better. I went to the bathroom and climbed into her shower while I was there. Millie rarely ever lets me into her room, let alone use her shower that somehow had better water pressure than the main shower. She really was a spoiled brat. And I guess I kinda did have something on her now. If she kicked up a fuss about me using her shower, I could easily tell Hannah about her going out last night...and she could just as easily tell Hannah that we kissed when she was drunk and I slept in her bed...okay, fine, no blackmail. I'll just have to hope that Millie has the same mindset. If last night was just a drunken fluke and she freaks out about it today, it could ruin this family. That'd be a great welcome home present to Dad, wouldn't it? Hey Dad! How was working three long weeks away from your beloved son and new family? By the way, we're moving out. No, I need to fix this. I need to treat Millie like a princess for at least the next few weeks, just until she feels satisfied and forgets this whole thing happened. If not forgotten, at the very least until she finds something else to throw in my face.
I rinsed my body of the coconut scented bottled soap, and my hair of the strawberry scented shampoo/conditioner hybrid, and stepped out of the steamy shower feeling like a million bucks. Even her towels were extra soft, even though they were too small for me. No wonder she was so entitled if she was used to this kind of treatment. I decided that I'd been here long enough, people might start to wonder why I'm not up yet so I reached down to grab my clothes, wrapped the towel loosely around my waist and held it by the side before making for the door.
Something happened in the next five seconds that scared me more than anything ever had at that point in my life. The door handle turned before I got to it. I didn't know what to do, I didn't have anywhere to hide. I was standing in the middle of the room, naked (with too small a towel) in my step-sister's room when the main bathroom was just two doors down the hall.
The door swung open. Millie stood there, as smug as ever, that feline's smirk with which she's always equipped. She looked as fresh as a daisy. Her makeup from the previous night was gone, leaving her natural beauty to take the stage. I could smell the strawberry shampoo from here, intoxicating. No longer in the clothes in which I put her to bed, she now wore a pink pyjama set. What looked like silk shorts that showed her hips very well due to how short they were, and a similar fitting vest top. In her arms she held a tray with a plate of breakfast food on it. She gently swung her body side to side slightly, adding to her teasing smirk. I saw her eyes give my mostly naked body a not-so-subtle look up and down and her smile widened slightly. My heart was pounding out of my chest so hard I'm pretty sure if you looked hard enough you could see it working overtime.
"Morning, Jayjay." She said, stepping into her room. "Get the door, would you?" I never moved so fast in my life, thank God it was Millie on the other side of the door but if anybody else saw me I'd have to come up with a reason fast as to why I was here. "Mom asked me to make sure you were up, and to bring you breakfast." She came up to me after setting the tray down on the bed, smoothly putting her arms around my neck and pulling me into a kiss. So much for worrying about her freaking out... It was like heaven all over again. I put my free hand into the small of her back and held her to me. Without the guilt of one of us being drunk I was able to almost fully let myself go in that moment. Her hands came down to feel my body and she moaned into my mouth, kissing me a little bit harder, sucking on my lip as if to let me know that she liked what she felt.
Her hand trailed down my torso, leaving me in goosebumps by the time it settled onto the towel that I was still holding with one hand, she leaned into my ear, gave the lobe a quick lick and whispered "this is a hand towel..." and in one quick motion she swiped it away before returning to my lips. My erection, growing steadily and quickly since the moment she stepped into the room, sprung from behind its soft Egyptian Cotton prison. Millie was quick to grab it at the base and give it a good hard squeeze causing me to squirm in her arms. I put my hands on Millie's shoulders and gave her a little push back, breaking our kiss, leaving a little connective string of saliva. She clearly liked this, giving me a look of pure lust and curiosity, as if she was waiting to see what I'd do next, and maybe hoping that it would be her that I do it to.
"Millie...we need to talk." I said, urgently.
"You can talk, I can listen. And I'm very good at multitasking." She said while rubbing her thumb across the slit of my tip, spreading pre-cum around the sensitive head and causing me to almost melt in her hand as I audibly moaned. She giggled at the sound. She then started walking me to her bed, guiding me by the cock as if it was a leash. How did this girl who was almost a foot shorter than me have such power over me? She positioned us so that I was facing away from the bed. She gave me a little peck on the lips again, before holding her hand to my chest and pushing me backward. The mattress caught me and it felt like I landed on a marshmallow. My eyes glanced to the breakfast tray sitting next to me as Millie positioned herself, standing over me between my legs. She was so close to me that I could feel the heat emanating from between her legs. "Mom worked hard on that, so you better polish that plate while you're here."
"No, look, Millie, this needs to stop. We've gone too far already."
"Why does it need to stop? Clearly you're as into me as I'm into you..." She got down to her knees, still holding my cock in her hands.
I watched her purse her lips together as she got closer to my cock. "You're my- ohhh fuck!" I felt her blow gently onto my cockhead, her lips barely more than an inch away from making contact. The sight of her so close to me and the sensation of her cool breath on my sensitive head was overwhelming, and in response my erection danced and leaked all the more as my body betrayed me.
Millie rolled her eyes, there's that bitchy attitude back again as if I'd said something lame. She continued to thumb my slit as she spoke. "Yeahhhh I'm your step-sister, yada-yada-yada. Key-word is step, Jayjay. We're just two people whose parents happen to be married. We're both 18 for god's sake." She looked at her thumb, how the tip of it shined with my clear pre-cum and sucked the juice off of it, releasing it from her luscious lips with a pop. "Nobody's going to jail..." she said tilting her head, staring at my cock with a look of intrigue and arousal.
"That doesn't change anything, our parents-"
"Don't you ever get sick of worrying about what other people want? Never stop to think about what you want?" She started climbing up the bed until she was perfectly positioned to look down on me as our eyes were level, her hands at either side of my head, her legs on either side of my waist. If she wanted to, she could put all of her weight right onto my twitching prick and I knew in my heart of hearts that it would be too much for me, it would send me right over the edge.
"If you want me to stop Jayjay, you could have easily thrown me off of you...I felt your muscles and you're as big as a building and you're wrapped around my finger." I was taller than average, but due to her short stature I must have seemed even taller. She started rotating her hips over my cock, not making contact but daring to. "If you want me to stop, all you have to do is say the word. 'Millie, never touch me again.' But you won't, will you? Because you want this." My hands were working their way slowly up her legs, feeling her smooth skin. "I think you want this more than I do, even."
That was it. One hand settled on her ass, the other hand returned to the small of her back and I spun us around. She gasped as our positions were reversed. I took both of her wrists and pinned them both above her head under one of my hands, my other hand kept me upright. She gasped a that, and I noticed for the faintest moment that she bit her lip. "Is that what you think? Tell me this, have you told your friends at school that your 'secret boyfriend' is your step-brother?" She said nothing. "Maybe you'd like me to."
A moment of weakness, a crack in her bitchy persona. For a second her eyes looked panicked. "I'm not going to." I let her arms free and I climbed away from her, standing in front of the bed while she sat up.
"You promise?" she said. It was the first time I saw her completely devoid of power, her trademark 'attitude', and I couldn't bring myself to savour it. Not over something like this.
"I already made a promise to Hannah, she wants you to stay out of trouble."
Millie rolled her eyes at this.
I crouched down so I was more at eye level with her as she was sitting down. "She told me to look after you. It'd be weird for me to destroy your social life after only one day of school, wouldn't it?
I smirked at this, Millie exhaled through the nose, offering a little smile.
"Besides, everyone at your friend's party saw us making out last night in my truck."
