My name is Benjamin Franklin Johnson, and my little sister is Abagail Adams Johnson. You guessed it. Our parents are into history. In fact, they are both history professors at our state university. Mom’s specialty is the mediaeval period, while my dad loves Early American. They swap off each summer’s vacation. Last year, we spent six weeks living in a cold, damp, and dark castle in France, not as landlords, but as servants. Now this summer, we are living in a cabin in the mountains of Kentucky for three full months. We arrived the day after classes ended, and we can’t go home again until after harvest, the week classes begin. The day we left our apartment, Mom inspected our bags for anything that was not pre-1776, including books, or anything electronic. I didn’t have a problem, but I overheard my little sister getting scolded for trying to sneak in her vibrator and cell phone.

Arriving yesterday, we quickly changed into authentic Colonial outfits and took a tour of the farm. Most of the spring planting had been done before we arrived, but we still had all the livestock to take care of and the crops to manage through the summer. The cabin was just one big room with a half-loft overlooking the living room and kitchen area. There was one bed under the loft where mom and dad would sleep, and two pallets in the loft for my little sister and me. Dad hung a blanket from the rafter, between the two pallets to give us a little privacy. It looked like a blue-ball summer for me.

Abi is 14, almost 15, and developing to be a knock-out like my mother. At 16, I have become an expert at peeking in on her and Mom every chance I get to see their beautiful necked bodies. Granted, they are just glances, and I have never gotten the opportunity to really inspect their nakedness, but a glance is enough jerk-off fuel to last a while. Abi has very little pussy hair and perky B cup boobs, while Mom is clean-shaven with very full C cup boobs.

Mom tried to cook dinner on the hearth by the fire, with tried being the operative word. It was edible, but not good. I tried to read my book by lamplight, but quickly gave up and settled for a game of checkers by the fire with Abi. The latter into the loft was steep, and the clearance was low, so we literally had to crawl into bed. It was very early, but with the trip behind us, I put on my long nightshirt and quickly fell asleep to wake up to the smell of bacon and eggs.

The gravy and biscuits were burnt, but the eggs and bacon were great. At breakfast, the four of us sat in our nightshirts and discussed what we were to do for our day. The only difference between our dress was that Mom and Abi’s nightshirts had a little ruffle around the neck. I couldn’t help but get a boner just thinking that under that bit of linen, they were both necked. Dad must have had the same thought because when we finished breakfast and our discussion, we both had lumps in our nightshirts, and I saw Mom and Abi had hard nipples. I needed to go to the outhouse as soon as possible to relieve this pressure.

I always jerk-off in the morning, either in bed or in the shower, in bed before going to sleep at night, and at least once or twice during the day as opportunity and stimuli presents itself. I was wondering how I was going to survive until I climbed into the hayloft to rake hay down to the cattle below. I saw Abi talking to the stud horse below and got a boner. Colonial pants were not designed for a quick jerk. I had seven buttons to undo to drop the front flap, two more to undo the waist, and suspenders to push off my shoulders before my pants dropped to my knees. Below me, Abi was bending over, inspecting the studs’ cock, and making lude comments about his equipment.

With my trousers finally on the floor, I grabbed my hard cock and in three strokes I was releasing all the cum that had accumulated over the last several days. I had to grab the rafter with my left hand to keep myself from falling as my eyes rolled back in my head. I had never had an orgasm this strong as I fired shot after shot of cum from my cock. Relief at last! Abi called from below, “Did you just spit on me?” I tried to speak, but words wouldn’t form. Finally, I said, “No. It must be sweat. It’s hot up hear.” As quickly as I could, I pulled up my trousers and re-buttoned them with shaking hands. I made my way down the ladder, stepped outside, leaned up against the side of the barn, still trying to catch my breath and slow my heart. Wow! That was awesome.

The rest of the day was taken up with chores around the farm. After dinner that evening, Mom told us to go to the creek and take our baths. We both stripped down to our nightshirts and taking a towel and a clean nightshirt with us, we went to the bathing places. There was a bend in the creek between two deep pools, with a spit of land between them. Mom had told us the up-stream pool was for the girls, and the down-stream was for the boys. There was a bar of lie soap on a string handing over each pool for us to use. I jumped in quickly and washed down as quickly as possible so I could look through the brush and watch Abi. She was up to her neck in the water washing her hair. When she was finished, she backed out of the water, dried herself off, and slipped on her nightshirt without turning around. All I got to see was her cute little ass. She didn’t even bend over when drying her legs. I didn’t get to see her boobs or her pussy, but her little ass was good enough for me. I dropped another load of cum on the ground.

When we got back to the cabin, Mom said it was their turn for a bath. Abi and I sat on the porch, enjoying the cool breeze, and played checkers. When they finally walked back to the cabin, they were holding hands. I’d be willing to bet they didn’t use two pools for their bath. It was getting dark outside, and on the farm, that meant bedtime.

Once on my pallet of quilts, I decided to wait until I knew Abi and my parents were asleep before I jerked off. I pulled my nightshirt above my waist and carefully held my cock and my balls, waiting. It was very dark, but Mom and Dad had a lantern on by their bed, which cast a gentle light in the cabin. Suddenly, I heard my dad moan. I rolled off the side of my pallet and looked through the crack between floor-boards. Dad and Mom both were nude and Mom was between Dad’s knees, obviously giving him a blow-job. I couldn’t see anything but her back and her bobbing head. I watched and started pulling on my cock. It didn’t take long for my dad to drop a load, and it looked like Mom swallowed it all down. She crawled up beside him and snuggled while he caught his breath. Then it was his turn. He crawled down between her knees and went down on her. Now I had a better view. She was pinching and pulling on her nipples, and I could hear Dad slurping up her juices. When she came, she put a hand in her mouth and bit down to keep quiet. This is when I exploded and dropped a load on the floor beside the pallet. I had not even realized I was jerking on my cock until I came. Dad must have done a good job, because she just kept coming and coming. When she finally relaxed, Dad crawled up her body, kissing her as he went until he was in position. I watched as Mom reached down and positioned him and he thrust forward. Mom’s feet were up on his ass pulling him in, and her arms were around his back racking her fingernails across his skin leaving marks. She was coming again and went from one peak to the next. With the blow-job he had received, he lasted a good 15 minutes before he came inside of her. It was at this point that I dropped another load of cum on the floor beside me. From the other side of the curtain, I heard my sister whisper, “Oh Shit!” so I knew she had been watching them too. I rolled over on my back, my now limp cock resting on my leg, and was asleep almost instantly.
