Step-Siblings Made to Share a Bed

"Time to wake up, sleepyheads!" my dad exclaimed loudly as we pulled off the interstate to our exit. Everyone must have dozed off as dad drove, because as I looked around, I saw my step-mom and step-sister blinking their eyes open and stretching as best as they could in the cramped car.

We've been road tripping around the country for the last two weeks, just to get from the west coast to the east coast. "One last family road trip before you two go off to college!" was how my dad and step-mom had sold the trip to my step-sister and I. The final stop was in Florida, where our parents had decided we would spend a week visiting beaches, hitting the theme parks, and taking a breather before they drop my step-sister and I off at our respective colleges.

A few minutes later, our car and the trailer full of my step-sister's and my belongings sat parked in front of a poorly lit motel. "This place looks like a dump," I thought to myself as I climbed out of the car and started pulling our suitcases from the trunk. I knew we were on a budget and we weren't planning on spending a lot of time in the rooms anyway, but I had a weird feeling about this place as I looked around. My dad had already gone inside to check us into our hotel rooms, whistling as he walked inside, leaving the three of us to pull suitcases out of the trunk and wait until he came back with the room keys.

My step-mom and step-sister were quietly chatting on the other side of the car as my dad walked out shaking his head. I knew that sign. He was about to break some bad news to us.

"Sorry gang, but it seems that there was a mix up with the motel. I could have sworn I booked a room with double beds in it for the two of you," he said indicating towards my step-sister and I, "but it seems like they only have single queen beds in each of the rooms here."

"No worries, Dad, I can sleep on the couch in our room and Michelle can take the bed," I responded, trying not to feel irritated at the situation.

"Well, that's the other thing..." my dad started. "The rooms each have the same set up: a bed, a table with chairs, and a built in dresser with TV on top and a side table area as a desk. No couches or anything. And before you ask, I already checked about a folding cot. It seems those are usually available but all of them are already in use this week."

"Whatever, it's fine, we'll share a bed. We can put a pillow between us and it won't be a big deal!" my step-sister said before I had a chance to voice my frustration and ask that we move to a different hotel.

My dad handed keys over to each my step-sister and I before grabbing his suitcases and waving my step-mom over as they walked towards their room while saying goodnight to us. I looked at my step-sister, who shrugged and started rolling her suitcase towards our room, right next to our parents room. "This blows" I thought to myself as I followed her, rolling my eyes as I realized that I faced a week of no jerking off in privacy while sharing a bed with my own step-sister.

It wasn't that bad, I guess. My step-sister and I were the same age: 18. Our parents met when we were younger, thanks to a school field trip, both newly single and struggling with single parenthood. They hit it off and eventually ended up remarrying, making Michelle and I step-siblings.

I was to stay in Florida to go to college while my sister was going to North Carolina for college. Our parents were right that we should try to make the most of this trip, because it might be a while before we were all together under one roof again.

My step-sister was quiet and introverted, preferring to have her nose in a book rather than playing sports or getting involved in school clubs. It wasn't uncommon to see her lounging by our pool reading while she tanned, wearing a bikini that showed off her soft, plump body and her hair in a messy bun on the top of her head. Despite being a bookworm, my step-sister had a close circle of friends and a boyfriend, all of whom she spent time with regularly. I wasn't sure, but I thought that at least one of her friends, if not her boyfriend, was going to be attending the same college as her in the fall.

I, on the other hand, was fairly popular at school. I didn't play any sports, but I was on the weightlifting team and had a toned body that got me a lot of attention from the ladies. Despite the popularity and ladies, I remained a virgin, having only received hasty blowjobs or handjobs from my girlfriend as we tried to hide our sexual relationship from her parents. When I told my girlfriend that I was going to college on the east coast, she broke up with me right there. I didn't mind, of course, she was right that a long distance relationship would just stifle us from having the "great college experience" that we were promised by parents, teachers and all the other adults in our lives. It was a clean and easy break, with both of us promising to stay friends and meet up anytime I was back in town visiting my parents.

My family took over a week to get from Washington state down to Florida, staying in crappy motels and sightseeing along the way. We always got two rooms so our parents could have privacy and my step-sister & I could have... well. No privacy. It wasn't a big deal, because at least we'd always had separate beds and I could sneakily jerk off after she fell asleep at night. But now? We had one bed to share and there was no way I wouldn't wake her up jerking off at night.

"This sucks," I said out loud as we closed the door behind us in our room, taking a look around as I closed the curtains that overlooked the parking lot.

"Tell me about it!" my step-sister said, commiserating with me. At least I wasn't the only one complaining about sharing a bed. Something about the way she looked when said it softened my annoyance a little bit. At least we'd be miserable together...

Having arrived so late, we took turns using the bathroom and brushing our teeth before climbing into bed. Michelle grabbed a pillow and put it between us to create a bit of a barrier before turning away from me and falling asleep. I tried to sleep, but sleeping in the car had been a mistake. I still felt wired from the drive, and needed to calm down a bit, so I quietly got out of bed and went into the bathroom to jerk off over the toilet. The bathroom door squeaked as I went in and out of the only private area of the entire hotel room, and I prayed I didn't wake my step-sister up as I climbed back into bed before falling asleep.

Thankfully, she didn't make a noise or move. Maybe I was in the clear.

The next morning, I woke up to find my sister reading in bed next to me and a hard case of morning wood. "I guess you didn't get enough last night" she said, sounding a bit amused as she dramatically closed the book to look over at me. I guess I had woken her up going into the bathroom to jerk off last night. I rolled my eyes, saying nothing, as I rolled out of bed. What did she know about masturbating to relax anyway?!

"Whatever. Anyway, my mom texted that she and your dad are going out to grab breakfast from the diner we passed on the highway before getting here. They said they'd bring us food and then we could chat about the plans for the day and the rest of the week", my step-sister shared as I walked to the bathroom. I shrugged and thanked her for the info before closing the door and taking a piss.

When I came out of the bathroom, my step-sister had gotten out of bed wearing an oversized t-shirt that covered her down to her thighs. I realized how tan and shapely her legs look as she bent over to unzip a suitcase and dig through it. I stopped to stare as I came into the realization that this girl I grew up knowing as my step-sister had grown into... well... a hottie. I coughed and turned to wash my hands as she stood up and walked towards the bathroom.

"I'm going to take a quick shower," she said as she walked to the bathroom and closed the door, leaving me stunned by the sink. I splashed some cold water on my face, shaking off whatever thoughts that were running through my head. Her legs were so tan with more muscular than I expected for a curvy girl.

I grabbed the TV remote and sat on the edge of the bed in my boxers, flipping through channels as I listened to the sound of the shower filling the room. I didn't realize the TV was muted until I started hearing what sounded like moaning coming from the bathroom. "Sounds like I wasn't the only one who had privacy needs in this stupid motel room," I chuckled to myself. I unmuted the TV and turned my attention back to trying to find something worthwhile to watch.

After a while, I heard the shower turn off and a few moments later, my step-sister opened the door, releasing a wall of steam as she stepped out wearing nothing but a towel wrapped around her. "Don't look, but these towels are way too small", she grumbled in annoyance, glancing down at her reflection in the mirror above the sink. The towel was secured over her chest, but her plump curves poked out as the towel struggled to contain her curvy bust, belly and ass. I tried to sneak a quick glance at her as she leaned over the sink slightly, her ass poking out from under the towel. How had I never noticed what a great ass she has?!

I shifted weight, realizing that I was getting hard again as I continued stealing glances at my curvy step-sister wearing nothing but a towel. I suddenly decided that taking a shower would grant me a few minutes of privacy to find release. I tried to push my growing boner down before walking towards the bathroom, mumbling something about how a shower sounded really good.

Closing the door and turning on the water, I caught myself thinking about how soft my step-sister's ass must feel. The water from the shower rained down on me as I jerked off, imagining my step-sister's ass jiggling in doggystyle...

Wait. What was I doing? That's my step-sister I'm jerking off to! I turned the water to cold and stepped out, realizing that I didn't want to finish while thinking of her like that. It was wrong to fantasize about watching her ass jiggle as I pounded my step-sister from behind. So why couldn't I get the image out of my head?

I wrapped the small towel around my waist before opening the bathroom door, only to walk right into my step-sister, still standing at the mirror as she put on mascara. She was still wearing nothing but that tiny towel as I accidentally pressed my hard cock against her.

I don't know which of us looked more panicked in the moment. This was a bad idea, I should have finished jerking off and let myself go soft, but it was too late. Michelle looked shocked, glancing back and forth between my embarrassed face and my hard cock. Neither of us said a word for a moment as we looked at each other, still just inches away from one another. The silence growing before her phone buzzed on the counter next to her toiletries bag, breaking the spell.

"It's a message from my mom. She said that the diner was further away than they thought and it's going to be at least an hour or two before they get back", my step-sister groaned. The moment was over, and suddenly we had a lot of free time to sit in that motel room together before our parents would get back. Rolling my eyes, I walked towards the bed, pulled on a pair of fresh boxers, and sat against the headboard, placing a pillow over my crotch so my boner wouldn't be so noticeable.

I was busy scrolling on my phone when Michelle walked from the vanity to her suitcase and bent over again, this time pulling out clothes that I assumed she was going to put on. As she bent over, the towel loosened around her chest and fell to her feet, leaving her stark naked just a few feet away from me. I couldn't look away from her voluptuous curves as I heard her quietly whisper "oops" without making any effort to pick up the towel and hide behind it.

What was happening? Why couldn't I look away from my step-sister? Why wasn't she trying to hide her nakedness from me? My brain was going a mile a minute as I looked at her. I could feel my cock growing harder under the pillow as she stood up and turned towards me. She didn't try to hide her big tits or belly, instead she stepped towards the bed. I must have had a look of surprise on my face, because she let out a quiet giggle.

"Like what you see?" Michelle asked me. I don't remember responding, but I must have nodded my head because she started moving towards me as she also ran her hands along her soft body. What was she doing? "Does she know the effect she's having on me," I thought to myself as my eyes followed her hands over her body.

I've seen her in a bikini, but this was something totally new. She was completely and totally naked. Her tits were big, hanging down above her chubby belly. Her hips were wide and soft, leading down to her pillowy thighs. I couldn't look away. I was mesmerized by the way her body jiggled and moved as she approached me. My eyes continued to follow her hands, but I barely remember them moving away from her body to pull the pillow away from my groin, revealing the tent I pitched in my boxers.

Her touch was soft as she took a single finger and traced the head of my cock over my boxers. A groan escaped my lips as I looked up at her. My eyes met hers, and I could feel a hunger building inside of me. She bit her lip as she glanced down to my cock before raising her eyes to meet mine again. I could see the same hunger building inside of her, but I was paralyzed by the moment. I could hear my heart beating in my ears, unable to say anything as I groaned again as her finger slowly swirled around the tip of my cock.

"We've got time," Michelle whispered in my ear as she bent down closer to me, her breath on my neck and ear sending goosebumps down my body. "I saw the way you looked at me before rushing in to take a shower. It was impossible to miss how hard your cock was when you stepped out of the bathroom. You practically impaled me on that thing," she said quietly giggling and whispering into my ear before standing up straight.

Hearing her giggle sparked something in me and I felt control returning to my body. Realizing I could move my arms again, I acted purely on impulse. I was horny and there was a gorgeous Aphrodite standing naked before me. I turned my body so my legs were hanging off the side of the bed, bent at the knee, my hands grabbing her by the waist and pulling her on top of me as we both fell back onto the motel bed. Her body adjusted to the movement, her legs spreading to either side of mine as she made a quiet moaning sound. Her soft belly pressing against my hard cock as her eyes met mine again. I quickly moved my hands from her hips, one grabbing her shapely ass and the other pulling her face towards mine as we locked lips.

Her mouth opened to mine as our tongues intertwined and a moan escaped from her lips. I couldn't believe what was happening and I didn't want it to stop. My hand left her face and slid down to her ass as I beheld just how soft and jiggly it really was. I started moving her body, making her grind against me as we kissed. My hard cock was still pressed into her soft belly, and the movement of our bodies caused her belly to gently rub against my cock. It felt so good, but I wanted more. No, not wanted... I craved more.

Michelle started to grind herself against me without my hands controlling her movements. Feeling her find her rhythm, my hands were free to roam the rest of her plus size body. We passionately made out as she dry humped me and my hands explored every roll, every inch of her soft body. I'd never felt someone so soft against me and I wanted more. I was hungry for her and I was confident Michelle felt similarly.

I was going to cum. I could feel it building as her belly rubbed against my cock, and I knew if I didn't move her, we'd both need showers again. I grabbed her thighs, pressing her against me as I rolled us over, a squeal of pleasure coming from Michelle as she was flipped onto her back. I stood up, her legs on either side of me hanging off the bed as I looked down and took in every inch of her softness, eyes devouring every inch of her softness. I didn't want this to stop and I was afraid that if I spoke, everything would end.

So I didn't give myself the opportunity. I slid down onto my knees before her, still between her legs. It was then that I saw my step-sister's pussy for the first time. It was clean shaven but the skin glistened from her wetness. I couldn't help myself. I was so worked up that I just dove straight in, burying my face between her thighs as I began to run my tongue up and down my step-sister's already wet slit. I heard a gasp as I reached my fingers up and slowly opened her pussy up, rubbing her wetness over my finger before I slowly slid it into her. As I started finger fucking my step-sister, I found her clit and focused my tongue on it. Her body shook as I alternated between licking and gently sucking on her clit. I could feel her pleasure building before her pussy clamped around my finger, giving her an orgasm.

My cock was the hardest I've ever felt as I continued finger fucking her and eating her out. I slid another finger in, even though I desperately wanted to bury my cock inside the wet pussy I was dining on, but the sounds of her orgasms were too good and I wasn't ready to stop. I occasionally stroked my cock as I ate her out, enjoying the way she tasted on my tongue. Michelle kept cumming on my finger and face, her moans filling the room as her body trembled.

"Fuck me," she whimpered. Her chest was raising and falling from the pleasure I was giving her, her breathing labored yet still asking for more. How much more could she take? I didn't know how many times I felt her pussy clamp down on my fingers while I ate her out, but she must not be done if she wanted more. I pulled my face and finger away from her as I stood up again.

"I have to tell you something first" I managed to get out as I stood admiring my step-sister's plush body. She moved herself further onto the bed, making space for me between her legs on the bed as she looked up at me. "I... uhh... I've never done this before," I stuttered out, shame filling me and causing me to turn my head away. I didn't see her reach for my hand, as she pulled me back down on top of her. "It's ok, I have" she whispered, as she reached between us and grabbed a hold of my cock.

I leaned back, putting my weight on my knees as Michelle slowly pumped my cock with her hand. She wiggled herself closer to me before she started rubbing my cock against her wetness. "Tell me you want it", she said as she smiled up at me. I nodded my head and that was all it took for her to slide my cock down her slit, then press it against her wet hole. "So take it" was all she said, grinning up at me. I pushed my hips forward, sliding my cock into my step-sister. Her pussy felt so much better than I ever dreamed...it was soft, warm, wet and ever so welcoming.

After a moment of feeling her pussy wrapped around my cock, I slowly started to move my hips, sliding my cock in and out of her pussy. It felt like heaven and I never wanted to stop. Her hands pulled my thighs closer to her, helping guide the rhythm and digging her nails into me as I fucked her.

My hands moved down her thighs and up her torso towards her big tits, bouncing in time to the motion of our sex. My fingers gently pinching her nipples as her face lit up in pleasure. Her moans filled the room as I increased my speed, Michelle's body jiggling along to the motion of my thrusts. The more her body bounced and jiggled, the more mesmerized I became.

I could feel her pussy pulsating around my cock, tightening with pleasure, gripping my cock tighter as I brought her to orgasm again. It was too much. I was going to cum. Sensing my urgency, my step-sister whispered "wait" and gently pressed a hand to my torso, pushing me back and causing me to stop. I slid my cock out of her pussy, grateful for a break. I didn't want to disappoint her by cumming too quickly, and I wasn't even sure where I should cum.
