My parents split when I was born and I'd never met my Dad. It was just me and Mum, and my childhood was great. When I was 8, she met and married a guy called Dean and he seemed great for me and Mum. He had a daughter who was three years older than me, Elyse, but lived part time between us and her Mums place. Dean was loving and caring of my mother, but he treated me and Elyse like shit. He wasn't violent, just obnoxious and emotionally abusive.

Things were ok though - I had my Mum, and Elyse was a genuinely kind and caring big sister to me. But my world was shattered when I was 15, my mum died in a car accident. Deans behaviour deteriorated into drinking, shouting and violence. I started crashing with friends and relatives until Elyse saved me...

She was 18 now, and had been working at her Mums business and made it very successful. I moved in with her in a nice apartment she rented in the city.

Elyse is the most beautiful woman I had ever seen in my life to that point. Tall and slim, her milky white skin is flawless. Smaller chested which makes her fond of braless outfits. Effortless style, and seems like she can pull off any hairstyle, any outfit, anytime. Around the house in the warmer months she would wear plain midriff singlets and panties or gym shorts, or sometimes just throw on one of my big tees which would hang just below her ass. We got on well living together, I was grateful she had taken me in and I was sure to be a good room mate and brother.

The first time I ever saw her naked was in this apartment. I had got off school early and let myself in. I assumed she'd be at work so I was surprised as I walked through the living room the bathroom door was open, and there she was, standing in front of the mirror plucking her eyebrows fully nude. She hadn't seen me, and I froze momentarily taking in the shape of her beautiful figure.

Not wanting to be caught perving, i made my presence known. "Ahem! Sorry Els, I'm home early". "OOo" she squealed, "shit you startled me". I turned to go to the kitchen but she stopped me: "how was school?" She asked. I stood in the doorway as we chatted for a few minutes, and she made no attempt to cover or hide herself. We had never really been naked around eachother as kids to my memory, but she seemed completely at ease now. She did seem to sense my awkwardness though. "Relax!" She chortled, then sack tapped me in the balls with the back of her hand. "Ooft" I doubled over in pain. "At least you're not hard you little perv" she teased. We chatted a little longer about a marketing project she was working on. She told me she'd been having "naked days" when working from home, and had even done a zoom meeting with the webcam carefully positioned above her chest so they wouldn't know.

I was a virgin and this was the first naked woman I had seen irl. My mind was flooded with uncertain arousal over my beautiful sister.

She eventually threw on one of my shirts, though I noticed later that she hadn't put panties on. While watching TV after dinner she sat on the lounge and I snuck glances at her perfect shaved pussy at every chance I got. She chatted casually about the show but I had no fucking idea what we were watching. I fantasised about her when I jerked off that night, and many more nights after that.

But life went on, and as years went by I graduated school, and moved out to go to university. We remained close siblings, sharing every achievement and disappointment in regular phone calls and visits.

I was 21 when Dean died. I had taken a graduate job and Elyse called me at work to tell me he'd had a heart attack. Neither of us were particularly devastated, but we agreed on the funeral arrangements and that he would want to be buried in his home city. We set dates and planned for us both to travel there.

Els was rich now. Her Mum had retired and left her the business which she had since built into a massive company and sold it for squillions. She'd had a few boyfriends and short relationships here and there, but never seemed interested in pursuing love. She paid for my flights first class, and booked us a penthouse suite at a ritzy hotel for the funeral.

When I arrived at the hotel, the concierge knocked politely before swiping the door lock. The door opened to the most amazing room I've ever seen. Marble everywhere, glorious leather sofas in a vast sunken lounge. Els squealed, barrelling towards me for a hug. We crashed into an embrace, having not seen each other for over 6 months. She was wearing the hotel bathrobe loosely tied, and unsurprisingly, her boob was half visible.

"Still frolicking around like a dirty slut" I teased, and poked her hard in her partly exposed tit. "Still a pervy creep" she retorted, wacking me in the balls. I turned to the concierge and gave him a modest tip "I'm guessing this room has been a revolving door of strange men since she arrived?" But he's a consumate professional and remained straight faced "Not at all, Sir" he said, backing out through the heavy double doors. "Just the maseusse, Sir" just barely cracking a smile as the doors closed. We burst into laughter. "Yeah I fucked the absolute shit out of that masseuse. I don't think he's coming back" she admitted sheepishly.

We spent the evening getting drunk on expensive champaign and eating ridiculously expensive room service food. Elyse had taken me to nice restaurants and holidays before, but this place was next level. "We are going for a sauna!" Shouted Elyse excitedly. "Downstairs in the gym?" I asked, confused. "No you peasant, the sauna in the room!". Yes, this room had an IR sauna, big enough for 4 or 5 people, and a floor to ceiling window with city views.

As we got to the sauna, she dropped her robe to the floor while walking. My heart fluttered as I was reminded of her stunning beauty. I gawked at her from behind, taking in the soft, light brown hair dancing over her slender shoulders as she walked, the smooth white skin of her back. My eyes wandered down her spine to her perfectly shaped hips and ass, flowing down to her smooth legs.

I undressed just out of her view and wrapped a towel before going in. She was already laid out on her back on a neatly laid towel. Again I can't help but take in her form. One leg bent up which she was habitually bumping against the wall. As her thighs opened and closed I could see her neat little slit open and close slightly. Her eyes were shut and her forearms were rested above her head. She seemed content and relaxed, and I continued to stare at her as I sat down.

"You don't mind a perv, but you can't drop your own towel?" She quipped as her eyes opened and her head turned towards me. Embarrassed, I didn't answer. "You were always a little uptight" she said dismissively as she turned her head back and closed her eyes again. But I worked up the courage to stand up and lay my towel on the bench. "Hah! Finally got you naked! I haven't seen you naked since you were a little kid. " we chatted away, relaxing in the intense heat. I was frequently distracted by the beads of sweat running down the sides of her body. I was consciously trying not to get hard, but the casual conversation kept me calm and relaxed enough.

Inevitably, the conversation turned to our sex lives and we both candidly shared our recent experiences. "Do you remember staring at my snatch on the sofa that night?" I knew immediately what she was referring to. "I wasn't staring!" I claimed defensively. "You were staring," she dismissed. "I was glancing". "Oh glancing...did you like what you glanced?". "I did". "You thought about it when you wanked that night". "I didn't wank!". "You did, I listened at your door and heard you panting and wanking. I rubbed my nub right outside your door. You wanted to fuck me perv". I was taken aback at this revelation. My dick is starting to firm up by now, but I've got it mostly under control.

"Sounds like it's you who wanted to fuck me. Why didn't you come in?" I teased. "Ewwww! I wasn't going to fuck my teenage brother you freak" she chortled as she sat upright. I have to admit to being disappointed at her rejection. I was silent as I stared at her. She was smiling her beautiful smile, sweat dripping steadily from her nose and chin. My gaze wandered to her breast, and I focused on a bead of sweat form on her chest and run down her little boob, just darting around her hardened nipple and dropping to her lap.

"But you're a man now". She stood and without hesitation sat on my lap, facing me. Our soaking wet bodies pressed together, arms wrapped around eachother and immediately into a passionate kiss. My heart exploded as I realised my teenage dreams were coming true. This was happening, and my cock was immediately hard. Her hand wriggled between our bodies and began stroking me. But not for long, she almost immediately lifted herself and guided me inside her as though she couldnt wait any longer. She was tight and wet, radiating heat from inside and out. She let out a groan as she slid down my shaft. We kissed and sucked eachothers sweaty necks frantically, as she rode my cock at a steady pace. As I lapped up her salty sweat I could feel her rock hard nipples rubbing against my chest, her sweaty wet thighs rubbing against mine. She pulled my hair and nibbled on my ear, whispering my name. "God you feel so good inside me" she murmured. "Good...so good" she repeated. I could tell she was close already, and sure enough she adjusted her position slightly to get a faster, deeper thrust down on my cock. She started pounding it.

SlapSlapSlap as her ass cheeks clapped against my thighs. She rode it like a champion, the upstroke taking the head of my cock all the way to her pussy lips, and thrusting down hard just before it pops out. Each stroke would slam down so hard she'd crush my balls against the towel underneath is. I felt her climax in her pussy first, convulsions streaming up her body. She let out a howl and squeezed me against her, no longer able to thrust she ground her pelvis against mine. That was it for me, and I came hard inside her. "I love you Els" I blurted out as I unleashed streams of cum. "Ahhh" she moaned as she felt my hot nut flowing inside her pussy.

We sat almost motionless in the same position as we recovered. My cock still in her but starting to soften. "It's fucking hot in here" she said. "Let's go for a shower"

We kissed and cuddled in the shower, exploring eachother with soapy hands. As I went to my room for bed she stopped me. "Your in the master sweet with me" she instructed. We went to sleep in eachothers arms. As we drifted off I mumbled "won't the hotel staff see us when they bring breakfast?" "Yes, probably" she replied quietly. "They know we are siblings...they dont know we are step siblings" I added. "Rooms this expensive come with discretion"
