I'd had the most unusual summer of my life. At 23, I came home to Seattle to attend grad school at the University of Washington. Once home, both of my 18-year-old twin sisters had propositioned me to be their first lover. After some hesitation, I obliged and ended up fucking each of them separately.
Fall came, and both my sisters went to live on the UW campus. I got busy with my grad program and well, we didn't see each other very much.
Mom wanted to change that and get us all together during the long winter break. Since there's no dad in the picture, I guess she felt obligated to help the family stay close. She had no idea how close us siblings were already!
The idea was to travel up to Mt. Rainer to our family cabin. It's a bit remote but has electricity. It's a huge log cabin, with plenty of bedrooms and a living room featuring an enormous stone fireplace. We'd spent a lot of time up there when I was growing up, so I had fond memories.
Since we hadn't been to the cabin in years, Mom figured we needed to stock up. The day before we left, we all helped load tons of stuff into our Cadillac Escalade. We put stuff on the roof but there just wasn't enough room, so we ended up filling the middle seat up to the roof.
That meant that Mom and one of us would sit in front, and the other two would be relegated to the very back. I'd been up late for days on a grad school project so told everyone I'd be willing to ride in back so I could maybe sleep.
"Shot gun!" my sister Casey called out.
Casey is one of my twin sisters. She's a minute or so older than Chloe and is the outgoing one of the pair.
Other than the personality difference, they are identical. Both with long light-brown hair, large, firm breasts, and athletic builds.
"Oh, all right!" Chloe responded. "I guess I'll ride with Jeff."
"Don't make it sound like such a punishment!" Mom said as she loaded the last of the items.
Chloe winked at me as she climbed in. "Don't worry Mom. I'll be fine. I won't hit Jeff too many times!"
"Chloe!" Mom chided.
It's a fairly long ride up into the mountains so we all settled in. Mom and Casey started chatting away in the front. With the car noise and the wall of cargo, neither Chloe nor I could hear a thing they were talking about.
I laid my head against a pillow and tried to sleep. I didn't last long.
Chloe leaned against me and snuggled. It was nice. In recent months I'd not seen much of her, so it was great to reconnect.
"I've missed you, Jeff," Chloe said, gently stroking my thigh.
"I'm trying to sleep here!" I said, teasing.
"How can you sleep when we have the back all to ourselves!" Chloe said.
I looked forward and tried to figure out a way that Mom might see us, but a solid wall separated us from the front seat.
I turned my head and Chloe immediately met me with her lips. They were so soft and gentle. She opened her mouth and let her tongue touch my lips. I returned the kiss and let our tongues tangle in the space between us.
I felt Chloe's hand rest on my dick. I hadn't had sex in months and my cock was itching for the warm pussies of my sisters.
"We have to be very quiet," I said softly.
"All the way back here?" Chloe said. "Hey Mom, how's it going up there!" she said fairly loudly.
There was no response.
"See?" she said and started undoing my belt.
I pushed my jeans and boxers down over my knees. Chloe bent over and put her mouth over my cock. It felt so wonderful to have her wet tongue licking up and down my shaft. She began sucking in and going up and down.
"Not too much," I said. "I haven't made love in a while so I'm kind of sensitive."
"Then why don't you go down on me," Chloe said, pulling off her jeans and panties.
She faced sideways and opened her legs wide. I could see her pretty pink pussy was already wet. Her petals were moist and inviting. I laid on my side and began rubbing her clit with my finger.
"Oooh!" Chloe purred.
I flicked out my tongue and began sucking on her clit and licking up and down her slit. I put two fingers in her pussy and began finger-fucking her.
"Mmm hmm!" she groaned. "I haven't fucked anyone since you, brother! I'm pretty sensitive too!"
Her hips began to shake. I increased my rhythm and soon I could hear muffled cries coming from her mouth. She was cumming right in the back seat!
When she'd finished, she pulled me up and we kissed.
"Now your turn!" she said.
"Me?" I said. "How?"
"Lay against the back of the seat and I'll lay next to you."
I pushed myself flat against the bench seat back and Chloe positioned her ass against my big cock. She began grinding into me and my dick separated her ass cheeks. I tried to feel for her pussy as I moved my member up and down her slit.
I found an opening and began to push.
"Shit!" Chloe said. "Where are you putting that?"
I was pretty caught up in my own feelings and continued to push into what I thought was her pussy. Chloe pushed back on me, and I slipped in the rest of the way - into her ass!
I was giving my sister her first anal fuck. I hadn't actually done this very much, but it felt great, different than a pussy. Her cunt is pretty tight, but this was even tighter. Her asshole clinched my dick, sending incredible feelings all up and down my shaft.
"You're in my fucking ass!" Chloe panted, pushing back and matching my rhythm. "It feels amazing!"
Soon we were both fucking hard. I'd pull out and Chloe would push back. I reached under her top and began feeling her large breasts. It didn't take long before I couldn't stand it anymore and felt that strong feeling of pleasure erupt from my dick and travel back into the rest of my body. I shoved my cock even further up her ass and started shooting a big load of cum into her.
When I finally pulled out, she reached back and got cum off her asshole and licked her finger clean.
Chloe turned to face me. "You naughty boy!"
"I'm sorry!" I said quietly. "I wasn't sure what hole I was going into!"
"It's okay. In fact, that felt wonderful. We will definitely have to do that again!"
We put our clothes back on and really did fall asleep for a while. We woke up to the car stopping. We were just sitting up when Casey opened the back door and peered in.
"Anything going on back there?" she asked with a smile.
"Just sleeping," Chloe said as she scrambled out.
Casey gave me a look as I got out.
"What?" I said.
"Nothing," Casey replied.
We went into a restaurant and ate lunch. Mom was really excited about the trip and seeing the cabin again after so long.
"We might even get some snow," Mom said, looking at her phone.
"That'd be cool!" I said. We loved the snow - cross country skiing, using our snowmobiles, and having epic snowball fights.
As we headed back to the SUV, Casey ran on ahead. "I get the backseat!" she said, climbing into the back.
"I'm still pretty tired," I said. "I guess I'll let you join me, as long as you let me sleep!"
"No promises!" Casey said as I got in.
