The next morning my gorgeous step-sister was in my arms, wearing nothing but a tank top and her black thong. I lay there holding her tightly, gently running my fingers over her shoulder, when we were both jarred awake by three thumps on the door.

“Ohhh shit, it’s my dad,” I whisper-yelled at her as we shot out of bed and scrambled for our clothes. I slowly made my way to the door while she pulled on a pair of pants and hurried to the bathroom to finish getting dressed.

“Hey, Dad,” I said as I opened the door.

“Morning, kid. Where’s your sister?”

“She’s in the bathroom, I think. I’m just waking up,” I said, stepping out of the room. “Let’s get some coffee and get back on the road?”

There was a shitty coffee stand at the corner. We headed down there. My dad and I got three coffees and looked at the car. Then we called the tire place. They wouldn’t be able to fix it for a couple of days but would send someone to pick the car up. Not an issue, we said—we’d just have to drive back out here on our way home to deal with it.

We headed back to the room where Ellie was waiting, fully dressed, her hair up in a messy bun, wearing shorts that barely covered her fat ass.

“Ohh, thank God—coffee,” she moaned as she sipped it, making my cock stir in my pants. We grabbed our bags and got on the road. She sat up front, and I sat behind her. It was a very quiet ride home. We didn’t say anything to each other the entire time. I realized we hadn’t spoken since last night. I felt like she was okay with what had happened—or even excited about it. I know I was. She’s gorgeous and perfect. Honestly, I just hoped she didn’t think I was weird or creepy.

We pulled up to the large house with about seven cars in the driveway. As we dragged the luggage in, the whole family came to greet us with hugs, joking about what we’d gotten up to in the hotel room like they secretly knew. It was very awkward. My cheeks were on fire, but Ellie played it so cool, like she didn’t mind at all. Some of our clothes were still wet and wrinkled, so she suggested we throw them in the dryer. We headed downstairs alone.

“Omg, I can’t believe we’re finally alone,” she said.

“What?” I asked, shocked.

She pressed her body against mine. Our lips crashed together, and our tongues started to wrestle, my arms around her tight waist, hers around my neck.

“I thought you regretted last night,” I said between kisses.

“Are you kidding? It was the best sex I’ve ever had.”

I lifted her up onto the dryer, pulled her panties down, and lifted her legs. I dove between them, licking and sucking on her clit, her feet resting on my shoulders.

“Please, my beautiful sister,” I moaned as I tasted her. She placed one hand over her mouth to muffle her moans and the other on the back of my head, keeping me right where she wanted me.

“Ohhhh my god,” she whispered—much louder than I thought a whisper could be. I looked up at her as she moaned in ecstasy while I pleased her with just my tongue. I found the perfect spot and flicked my tongue from left to right as fast as I could. Her grip on the back of my head tightened as she started moaning louder. She grabbed her panties and stuffed them in her mouth to try to keep herself quiet. Her legs started to shake as she came, the sound muffled by her own panties.

I came up. Her legs dangled, almost like they didn’t work anymore. She pulled me in for a kiss, tasting herself on me.

“Mmmmm… I taste good,” she whispered.

“You taste amazing,” I whispered back and kissed her again.

That’s when we heard footsteps coming down the stairs. She hopped up, pulling on her shorts as I wiped my face. My grandma walked in and asked what we wanted for lunch.

Grandma, get the fuck out of here, was all I could think. I just had lunch…

But instead, we both said we’d have the chicken salad.

She smiled and headed back upstairs, leaving us alone again. Ellie turned to me and kissed me once on the cheek.

“I guess I owe you now,” she said, then headed upstairs.

My cock was rock-hard again at the anticipation of what “owe you” meant. I followed a few seconds later and rejoined the family. We spent most of the day playing board games and sneaking glasses of wine behind our parents’ backs. When everyone else decided it was time to head to sleep, I was still so fucking horny. I was sharing a room with two of my cousins, and so was she.

About an hour later, I still hadn’t fallen asleep, but everyone else in my room had. I heard a light tap at the door. I silently got up and opened it. Ellie stood there in a black nightie. My jaw literally dropped. Her cheeks turned bright red as she reached out, grabbed my hand, and whispered, “Come on,” leading me to the living room on the far side of the house.

She turned around. Our hands explored each other’s bodies as we started making out again.

“I can’t get you out of my mind,” I whispered in her ear.

“I know. You’re all I’m thinking about,” she whispered back. “This cock is just so perfect.” She grabbed my already hard cock through my boxers, then dropped to her knees, pulling them down. Her tongue wrapped around the head before her lips closed over it. She slid my cock to the back of her throat, taking about three-fourths of it, and grabbed my balls as her head began to bob back and forth. She pulled off and ran her tongue along the underside, focusing on the tip.

“OMG, I want to fuck you so bad,” I groaned.

“You wanna fuck your little sister?” she asked innocently.

I looked at her, a little nervous, then answered with confidence. “Yeah. I wanna fuck my little sister.”

“Mmmm… you’re a bad boy,” she responded.

Fuck, that was such a turn-on, I thought.

“You’re a bad girl,” I said, and pushed her over so she was bent over the couch, exposing her beautiful pussy. I ran my spit-slick cock against her wet lips. She turned and looked back at me as I pressed inside. We both moaned in unison as her tight lips wrapped around my thick cock. I opened her up for the second night in a row, my hands gripping her waist as I slowly pushed all the way in and held still while she adjusted to my size. Then I pulled out and did it again… and again. Her moans got louder as I fucked my step-sister’s pussy. Her right hand moved down to play with her clit while my pace quickened. Soon I was pounding into her hard and fast. She stopped playing with her clit; both hands covered her mouth to keep herself from screaming as I fucked her as hard as I could. She started to squirt all over the leather couch.

“Ohhhh fuck,” she yelled. “Sit. I wanna ride you.”

I sat next to the wet spot she’d left. She straddled my legs, grabbed my cock, and within seconds I was back inside her. I felt her ass bounce on my cock while her big, beautiful tits rubbed against my face. I grabbed them, licking and sucking on her nipples. Her hands rested on my shoulders as she bounced up and down, then leaned in and kissed me.

“Fuck, I’m gonna cum,” I warned, trying to lift her off, but there was no stopping her. She kept bouncing.

“Ellie, baby, I’m gonna cum.”

“Cum inside of me,” she moaned in my ear.

“Ohhh fuck,” I moaned back. “I’m cumming… I’m cumming, baby.”

I exploded inside her as she started cumming again.

“Omg,” Ellie said breathlessly. “That was so fucking good.”

“I don’t ever want this weekend to end,” I whispered in her ear.

“Me either.” My hands gently caressed her back.

“Ohhh fuck,” she said with a little laugh as she hopped up and ran off to the bathroom. I lay there naked, my cock covered in both of our cum. She walked back in.

“We should get to bed. Don’t worry—I’m on the pill.”

“Nice,” I said, kissing her and holding her hand as we headed back to our respective bedrooms.

“Good night, Ellie,” I said as I kissed her.

“Good night, stud,” she said, quietly walking back to her room.
