It was almost dark by the time we woke up, Fiona still laying on top of me. “I’m hungry,” she said. “Will you fix us something to eat? Then we can watch movies downstairs all night long.”

“Sure, Fi, I think there’s stuff to make sandwiches.”

“Thanks, Bro. I’m going to cleanup and put PJ’s on.” We climbed out of bed, I went to my room to put a pair of boxers on, and then I went downstairs and fixed fruit and sandwiches for us.

When I brought the tray of food out to the living room, Fiona was already there wearing an oversized tee shirt that hung to just below her ass and she was rummaging through the collection of DVD’s. “What do you want to watch, Matt? Action, romance, comedy?”

I put the tray on the coffee table. “Comedy would be fine,” I answered as I took a sandwich and began eating. Fiona put in a disc, took her sandwich, and we ate while watching the movie.

Just about the time we finished eating, Fiona’s phone rang. It was Mom. Fiona answered it, “Hi, Mom,”

I could hear Mom on the other end. “Hi dear, How’s everything?”

“Everything is fine,” Fiona answered.

“Is Matt taking good care of you?”

Fiona looked at me with her devilish grin. “Yes, Mom, Matt’s taking very good care of me.”

“That’s nice, you two are getting along. What are you doing?”

“We’re sitting in the living room watching porn.”

“There’s no porn at the cabin.” Mom admonished.

“I’m just kidding, Mom. We’re watching a movie.”

“Have you eaten?”

“Yes, Matt fixed fruit and sandwiches. We’re not starving.”

“Then I’ll let you two get back to your movie. Love you, bye.”

“Bye, Mom.” Fiona hung up the phone.

“You’d better be careful what you say to Mom, she’s pretty sharp. We don’t want her catching on about anything.”

“Stop worrying, little bro,” Fiona said cavalierly. “Mom’s not going to find out we’ve been fucking our brains out up here.” She stretched out on the couch and put her head in my lap and a hand up my boxers. Yesterday that would have freaked me out and sent me running to my room. Today, I welcomed and expected it.

I pulled Fi’s tee shirt up over her hip and rested my hand on her magnificent butt. She wasn’t wearing panties. We watched the movie and slept the night on the couch, Fiona with her hand up my shorts rubbing my cock, and me with my hand massaging her ass.

We awoke late the next morning, the sun was already high in the sky and the dew had burned off the leaves on the bushes. Fiona jumped to her feet. “Let’s have some breakfast and then go out in the boat,” she announced.

“Sure,” I blearily responded. I didn’t have much choice in the matter. This was her vacation, so we go by her rules, and we fulfill her desires. We had coffee and cereal, and then dressed to go out on the lake.

I dragged the boat to the waters edge and then alongside the floating deck. Fiona came down the deck with towels and a cooler full of cold drinks. She wore a tiny pair of red shorts with a white stripe on each hip and a white bikini swimsuit top. She looked particularly enticing in the morning sun. I helped her into the boat, and then got in myself. We pushed away from the deck and I began to row. “Where to?” I questioned.

“Anywhere out on the lake. I just want fresh air, sun, and to relax.” I rowed straight out to the middle of the lake while Fiona stretched out in the back of the boat, eyeing me as I worked. After a short while, that suspicious wry grin came across her face.

“What?” I asked.

“You’re bulging,” she replied.

“I’ve been working out.”

“I can see that,” she said. “Your shoulders are wide and your biceps are flexing, but that’s not what I’m talking about.” She stretched her leg toward me and put her foot in my crotch. “I’m talking about here.” Then she began rubbing me through my shorts with her foot. My dick started to become hard as her cute little foot worked over my groin.

“Fi,” I said, “you’re making it hard to row this boat.”

“That was my intention, to make it hard.”

“Well, you’ve succeeded,” I said. By this time my growing erection was beginning to bind in my shorts. I squirmed around in the seat trying to readjust everything into a more comfortable position while still rowing the boat.

“Oh, little bro, are you having trouble there?” she asked while still continuing to rub her foot on my crotch.

“Yes, thanks to you. You’re making it very difficult to row.” She removed her foot and knelt between my legs. Then she unfastened my shorts and pulled my fully erect cock out from the confines of my clothing. She fondled me for a moment, then leaned in and put her lips around my glans, the soft, moist sensation sending a shiver throughout my body.

“Fi, we’re in the middle of the lake. Somebody might see what you’re doing.”

She stopped sucking my cock. “I’m below the edge of the boat, nobody will see. They’d have to be standing on the roof with binoculars to see anything.” She put her lips back around the head of my dick and proceeded to run her tongue over my glans.

I looked at the houses around the lake and didn’t see anyone who could be watching, but I was still apprehensive. My anxiety quickly faded as Fiona worked on my dick, the head of my cock quickly becoming numb from the intense stimulation. Fiona began to slide her lips down my shaft, still working her tongue over and around the glans. The rush of sensation made it difficult to row. She slid the entirety of my cock into her mouth and gagged slightly as the tip contacted the back of her throat. Then she worked her tongue over the shaft and bobbed her head, pressing her lips around my girth as she slid up and down my length.

“Fi, you’re going to make me cum,” I said while trying to row and not blow my load at the same time.

She picked her head up off my cock. “No you don’t, I want you inside me when you cum. You’re going to fuck my brains out and cum in my pussy.”

“We can’t screw out here. Somebody will see that, even if they’re not standing on the roof.”

“Then go into the cove. Nobody can see us in there. You’re going to fuck me blind, Matt.” I rowed furiously toward the cove while Fiona went back to sucking my cock. I had to take my mind off what she was doing to me and concentrate on getting us to the cove before I exploded.

As soon as the boat cleared the entrance to the cove, I shipped the oars and removed my shorts. Fiona got up off her knees and removed the tiny shorts she was wearing. Momentum carried the boat into the cove. Fiona sat on the oarsman’s seat, leaned back, and supported herself by resting her elbows on the seat behind. She picked her legs up and spread them high in the air, parting her pussy lips and revealing her beautiful pink inner labia and glistening wet vaginal entrance.

I moved between her outstretched legs, positioned my cock at her corona, and supported myself by placing my hands on the seat behind. I drove into her in one long smooth plunge, her vaginal walls expanding as my cock invaded her body. She gasped and kicked her heels high into the air, straightening her knees and spreading her legs widely.

“Oh my god, Matt, your dick is amazing,” she said as she closed her eyes and leaned her head back. I plunged in as deeply as I could, the end of my dick contacting her cervix. “Ahhh,” she screamed as I hit bottom. I moved rapidly in and out of her slick pussy, plunging all the way inside, nearly knocking her off the seat with every thrust.

“Fuck me, Matt. Fuck me,” she encouraged as I worked. The boat carried to the opposite side of the cove and came to rest against the bank. I continued thrusting inside her, plunging in as deeply as I could, the boat rocking and splashing as I did.

“You’re making me cum, Matt. I’m cumming.” I felt her kegel muscles tighten around my shaft. It brought me to the edge and the urge to cum swept over me in a torrent. I exploded inside her pussy, ejaculating as I plunged deeply into her vagina. “Ahhh,” she screamed as we came together. Her pussy juice and my semen combined and squished out from her vagina as I continued to thrust deep inside her body. “Ahhh,” she screamed once more as I continued to cum inside her, releasing a huge load and draining my balls.

I was nearly out of energy and completely out of cum. I slowed my thrusting until I came to a stop with my dick inside her vagina and my groin resting against her vulva. She wrapped her legs around my hips and held me in place. Her legs were soft, but very strong, and it was a good thing, because I was so exhausted I would have slid off of her if she hadn’t held me with them. I leaned in and kissed her soft, sweet lips and we stayed in that position until I could muster up enough energy to climb off of her.

When I had recovered enough, I got off of her and collapsed into the bottom of the boat. “I can’t row back just yet,” I admitted as I lay in the bottom of the boat.

“That’s alright, Matt, you just lay there until you’ve rested. We have all day.” She put her clothes back on and helped me put on my shorts. Then she lay down in the bottom of the boat and held me until I had recovered enough to row back to the cabin.

* * *

The next three days were much like the last two. Fiona would pick the place and we would fuck until we dropped. We hiked into the woods with a blanket and fucked. We fucked on my bed, and we fucked on her bed. We fucked on the couch and on the living room floor. She was insatiable, not that I was complaining. She was an absolute glorious lay, with her tight body, perfect pussy, casual attitude, and willingness to do anything.

I didn’t know anyone could have it so good, and her being my step-sibling didn’t dissuade me from wanting her constantly, nor her from wanting me. It was like a fairytale without an end and we acted accordingly. It was too bad that at some point I knew it had to end.
