My stepsister and I were driving to meet our parents and some extended family for Christmas. We had both just finished our first semester of college, and we still had a few more hours of driving left in an absolute downpour.

Ellie was fast asleep when a tire blew.

“Ohhh shit!” I yelled, slowing the car to a stop.

“What’s wrong?” she asked, barely awake.

“A fucking tire just went flat.”

She sat up, rubbing her eyes. “We’re in the middle of nowhere… That’s like horror-movie shit, dude. Get us out of here.”

“Chill out. Let me go check for the spare. We’ll be moving in no time.”

I stepped out of the car right into a deep puddle, shoes instantly soaked. I moved to the trunk, pulled our bags out without thinking, and dug out the spare. When I got it over to the flat tire, I noticed something strange about the spare—it was flatter than the one already on the car.

“FUCK!” I yelled to no one in particular. I threw the tire back in the trunk, tossed the bags on top of it, and climbed back into the driver’s seat, defeated.

“The spare is bad,” I said.

“What do we do?” she asked.

This was the nineties, before cell phones solved every problem.

“Shit, I don’t know. There’s a motel about a mile back… or we can sleep in the car.”

“I don’t want to spend the night here.”

“So we’re walking,” I said.

“I hate you,” she replied.

“Yeah, feelings mutual.”

I didn’t really mean it. She was fucking gorgeous—hilarious and so sweet. To everyone else I was just her nerdy stepbrother. The first time I met her I’d been pissed she was my stepsister: short, stacked, with big tits and an ass that went on forever. But I was her big brother now, and those thoughts were supposed to be a waste.

We opened the doors, grabbed our bags, and started heading back down the road. The walk was silent as we trudged through the rain toward the shitty motel, nothing but a flashlight giving us any ability to see. It was a beautiful sight when the lights of the motel finally came into view. By the time we got there, we were both shivering.

We walked through the door to find a sleeping guy at the front desk.

“Hey, man, we need a room for the night. And maybe someone who can tow a car.”

The very scary-looking guy behind the desk blinked awake. “We have a room available, but no one’s around for towing tonight. You can call in the morning.”

I paid in cash. We made our way to the room. Ellie went straight to the bathroom to clean up while I called my dad to let him know what was going on.

She came out a few minutes later wearing just her panties and bra.

“Just one towel, bro, and all of my clothes are soaked.”

“Are you serious?” I responded, taken aback as I looked up at her. Damn, I thought. Tonight is going to be brutal.

I got up, dried myself off as best I could with the already-damp towel, and walked out in just my boxers. I might have been Ellie’s nerdy stepbrother, but I was the nerdy stepbrother who had spent the last year trying to change that. Getting ready for college, I’d worked out every day. I was pretty happy with the results. Don’t get me wrong—I still loved Dungeons & Dragons. I could just bench three hundred now.

She was already lying in bed with the blanket covering only her legs. I walked out into the room in my boxers, my cock bouncing freely. I could see her gaze locked right on it. It made me smile from ear to ear. I climbed into bed next to her.

“So what’s the plan?” she asked.

“Tomorrow morning I’ll call the tow guy and we’ll figure it out. Worst-case scenario, Dad has to come pick us up.”

“He won’t be happy about that.”

“What, a few hours away from your grandma? I don’t think he’ll mind.”

We both laughed.

“Would you mind coming over a little closer? I’m so freaking cold,” Ellie asked.

“Ummm—”

Without waiting for a response, she moved her perfect, mostly nude body against mine. My dick went almost instantly hard. Thankfully, it was covered by the blanket. I wrapped my arms around her as we tried to stay warm. I’m not sure when or how, but eventually I fell asleep.

“Mmmmm…” I moaned. “Fuck, that feels good.”

I opened my eyes. My stepsister was between my legs, stroking my eight-inch cock.

“Dude… what are you doing?” I asked.

“You had a big problem. I was just trying to help.”

“But you’re my sister.”

“Just step,” she said, leaning down and wrapping her lips around my cock.

“Ohhh fuck… no, you should stop,” I said, unconvincingly.

She didn’t stop. She moaned around my cock as her head bobbed up and down. I moved her hair behind her ear while she worked me, her gorgeous eyes locked on mine.

She pulled off for a second. “I figured you wanted this, from how much you were grinding on me.”

“What?” I asked.

“Were you really asleep?” she asked.

“Yeah,” I exclaimed.

“Your hands were gripping my hips, and you were rubbing this giant cock against my ass for like forever. What’s a girl to do? I had to investigate.”

“Holy fuck,” I said.

“You wanna eat my pussy?” she asked.

Two seconds went by, but it felt like a lot longer.

“Yes. Yes, I do,” I said, rolling her over, getting between her legs, and spreading her wet lips. I ran my tongue from the bottom of her pussy up to her clit. Her hairless pussy tasted so good. I held there a moment, adding a little suction, then started flicking my tongue from side to side. She lifted her legs, giving me more access. I slid a finger into her, then another, rubbing her G-spot while I stayed hyper-focused on her clit, tongue flicking fast, fingers sliding in and out.

Her hands found the back of my head, gripping my hair as she ground against my face. My soaked fingers slid out and down to her ass. I teased the tight entrance as her moans intensified, then slid a finger into her.

“Holy fuck,” she yelled. “Deeper, Brandon,” she whispered.

I pushed the finger deeper. Her grip on my head tightened, and her thick thighs clamped around the sides of my head like she was trying to crush me. Her hips lifted off the bed, holding me in place.

“I’m cumming—I’m cumming—” she whispered, then yelled it out loud. She collapsed back onto the bed, body shaking just a little.

“Ohhh my god, that was so good.”

I came up for air. She pulled me into a kiss, arms around my neck, tongues wrestling.

“You gonna fuck me?” she asked.

“Can I?” I asked, almost innocently.

“You fucking better,” she responded.

I rubbed my hard cock against the soaked lips of her pussy. Her moans filled the room as I pressed the head in slowly.

“Ohh shit, you’re big… be gentle, Brandon,” she pleaded.

“I’m sorry, sis,” I said, easing deeper. It felt so good. I pulled back slowly, then pressed in again. My pace quickened. I put her legs on my chest and started sliding in and out faster and harder, hands exploring her body. She moved her right hand to her mouth, sucked on her fingers seductively, then slid them down to her clit, playing with herself while my cock slammed in and out of her.

“Ohhh fuck, Ellie, you’re so tight,” I moaned.

“Mmmmm, fuck, that feels so good, Brandon,” she said as I pounded into her.

She moved her feet so they were pressed against my face. I grabbed her left foot, ran my tongue up her big toe, started sucking on it, biting a little, then made my way down to each toe in turn.

“Ohhh fuck, sis… I’m not gonna last long,” I warned her.

“Cum on my face.”

I pulled out, stroking my cock as I moved up to her face. She opened her mouth just in time. I exploded, cum shooting into her mouth, down her chin, covering her face.

“Omg—” she said in surprise as I painted her. She wrapped her lips around the tip of my cock, cleaning it off.

“Holy fuck,” I exclaimed. “I don’t think I’ve ever cum so much. That was so fucking good.”

“Yeah, it was,” she agreed, squeezing the last drops out and licking them off my tip.

We lay there for a few minutes in silence before she got up to clean herself off.

Omg, I can’t believe we just fucked, I thought to myself.

She walked back into the room and crawled into bed, snuggling up against me.

“Thanks,” she said. “I needed that.”

“You did?” I said, laughing.

“What? Why are you laughing?” she asked.

“Because I’ve wanted you since the day I met you. You’re like the best girl I’ve ever met.”

“I hope this wasn’t the last time,” Ellie said.

“Me either,” I answered as we drifted off to sleep.
