The indigo black lakeside sky was littered beautifully with twilight stars. Inhaling deeply, I tried my best to relax before walking the cobbled path down to the lower floor of the cabin where our bedroom was. These old cabins were always piecemealed together, jumbled without much thought. Unfortunately, for me, there was no chance of accidentally bumping into my daughter late at night with this type of room arrangement.
With the granddaughters fast asleep, I imagined that my daughter, her husband were settling in for the night. I wondered if she would dream about me? About us. Subconsciously my hand slid under the elastic waistband of my pjays ever so lightly touching my sensitive hardness. With just the whisp of my finger, it erected like a veiny iron bar. I twirled my finger around the frenulum and ridge of my cock for a couple of minutes before opening the door beside the garage that was the entrance to our bedroom. The nightstand light was still on and my wife opened her sleepy eyes as I clattered the ill-fitting door open. That was a mistake, I thought to myself, as I tried to figure out a way to climb into bed, without her noticing my flagging erection. I hesitated only a second or two. To hell with it! I dropped my pjays on the floor and lifted off my t-shirt.
"Oh! You're really hard! Why are you so hard?" She smirked naughtily and bugged her eyes out, wide awake.
I didn't want to explain the real reason why. That I was illicitly having a sexual interplay with our daughter. That it was more. That she watched me masturbate.
"Yeah, I guess I'll just have to fuck you, to take care of this, won't I?" I hopped up on the bed pulling the covers off of her.
"Oh, will you?" She chuckled, sounding as if she was a little hard to get.
That wasn't happening. I grabbed the panties from her hips and ripped them down. Pushing her legs wide apart. I forced myself between them and lifted her nighty until I uncovered her breasts.
"Oh, you're being bad." She teased mocking that she was a prude, holding me off with her hands.
Without waiting for her to even get moist I arched my back and I drove my steely cock as deep as I could. Her pussy lubricated almost as fast as I fucked her.
"Oh geezuz, fuck." She was enjoying the fast, hard, dominating, and ravishing fuck.
My cock was so erect and sensitive and with each quaking thrust, my climax closed in.
I closed my eyes, thinking of Christine. Imagining I was incestuously fucking her daughter for the first time as I pounded the fuck out of my wife.
"Christ, fuck!" The point of no return had long past and the pent-up sperm powered its way up my urethra. "Fuck, Fuck, FUCK!" I was pumping her full of my boiling seed while thinking incestuous thoughts of her daughter.
"Wow, what made you so fucking horny?" She asked as my cock oozed the last drops of spunk inside her.
I panted with my hips locked to her pelvis still shaking, trying to concoct a response. "Must be all the fresh air and relaxation," I smirked. In my mind I answered truthfully, must be the dad-daughter fun me and Christine had!
Utterly spent, selfishly I rolled off and flopped on my back beside her.
It was several minutes by the time my wife made her way back from the trail upstairs to the bathroom.
"You had quite a load." She jerked the covers quite a bit, climbing back into bed next to me. It seemed like she wanted to have a little bit of lovey-dovey talk before going to sleep again.
"Uh-huh." Keeping my eyes almost completely closed, my response was not much more than a murmur. My mind was elsewhere and I didn't want to talk. I cozied my head in the plush pillow wishfully hoping it would be a night full of erotic forbidden dreams involving Christine.

Shit, I slept in and was behind schedule for our dad-daughter morning workout routine. In my mind, I was already imagining my daughter's skin tight workout outfit. Fuck-it. I skipped the shirt, the mirror, and everything else, threw on my gym shorts, and made a b-line for the sundeck. Possibly the last morning workout together before we had to end our vacation. Christine beamed a glowing smile when I crested the cabin path to the sundeck. The sun shimmered off her perspiration further accenting how sexual she appeared to me.
Christine's eyes followed me when I claimed my side of the sundeck and started doing jumping jacks. My eyes gravitated to her clingy cameltoe then up to her pointy nipples. The pale beige skin-coloured fabric left nothing to the imagination.
"You have such a great body, daddy."
"So do you love, so sexy." My eyes x-rayed her pubic mound.
Christine caught my gaze. With her back to the cabin window, distinctively she mouthed the words 'no panties' at me then carefully traced her finger upwards in a line between her labia before moving to her next workout routine.
No panties, shit! My cock spirited to a steely pointing rod, not at all concealed by the track shorts. I turned my back away from the cabin window as well. What a tease!
Typically, I didn't have to avoid hammering my cock into the sundeck, during a push-up set. Flopping on the mat, I noticed Christine adjusting the music selection on her outdated iPhone. I stood up and tugged on my shorts, fantasizing about a much sexier workout. Looking over her shoulder I pretended to be scrutinizing her music choices. "You like teasing daddy, don't you?" My loud breathy whisper was close to the back of my daughter's neck.
Christine turned the side of her face into my breath and gave my cock a quick grasp by rotating her wrist back. "I think my daddy likes it."
I went back to my mat to do some side planks strategically facing away from the cabin windows. That's the only exercise I could think of at the moment that would not have my cock flopping around like a phallic pendulum.
My daughter aligned her blue yoga mat, so it was next to mine, took a look at my heavy cock, and smirked proudly. "Looks like another muscle needs exercise daddy!"
"I'm going to make you massage a muscle for me." I retorted seriously.
Christine was doing some mountain climbers, l looking at me and smiling. "I'll make you do some ab exercises... on me daddy!"
Jezus fucking Christ! She was making me even more turned on. "Or you can do some deep leg squats on dad's cock. One good turn deserves another, doesn't it Christine?"
I lost track of my exercise routine and sat down on my butt, trying to figure out how I would get my erection to go down before breakfast. I looked over my shoulder at the window. Luckily no one was paying attention to us.
Christine paused for a bit before responding. "Only if daddy sucks my big tits."
"I ain't got nothing," I replied, genuinely knowing any more sexual flirting would have me practically wanting to rip off that clingy gym-wear and fuck her in front of my wife and her husband!
My daughter stood up and tapped her cell phone screen. She gave me a hair fling and over the shoulder fuck-me daddy smile before entering the cabin.
I inhaled so deeply anyone watching would have thought I just held my breath for two minutes. Fuck so fuckable, and so very dangerously playful, if anyone had noticed we'd be in so much trouble.
Rather than enter the cabin with my never-say-die hard-on, I headed down the cobbled path and across the road to the lake, hoping the glassy cool morning water would temper my erection. Five or ten minutes of standing in the water and stubbing my toes on the sharp rocks of the lake bottom, fortunately, did the trick.

Breakfast seemed especially summery and fun that morning. Our granddaughters' batteries were fully recharged after the night's sleep and I had a blast trading cereals and helping make the table a mess until they were done.
To date, this had been bar-none the best, but riskiest summer holiday ever and had me alternating between feeling thrilled, appreciative, then anxious and hesitant. Daydreaming about the multitude of outcomes, I felt myself pensive and drowning in thought until Christine came over to wipe off the kitchen table. She put her hand on my shoulder softly, caressing it. My sense of hesitation disappeared as she massaged her fingers softly into my tense neck and shoulder muscles. Every lusty daydream and sexual innuendo that I could think of I imagined being transmitted with her touch.
I pursed a close-lipped grin at my daughter while she rinsed the washcloth. Her responsive smile mirrored everything I was feeling about our secret love. Everything good. Everything tempestuous.
Nothing overtly sexual, nor any moments of escape occurred during that last beach day, however many of Christine's glances back at her dad carried that loving smile she shared earlier in the morning. It felt very special. Flirting and fulfilling. Confirming our love. Confirming our incestuous desire.
Despite our best efforts to extend the last beach day of our time together, it passed too quickly. Tidying up the beach gear, dinner, and evening activities centered around the grandkids.
