It was the summer of 1968, I had just turned 18 and went to help my Grandfather on his farm in Kentucky while I waited for the draft to catch up with me. Being the only Grandson out of 14 grandkids, I thought I might help out with the chores and in the fields until Uncle Sam came calling.
Grandpa and I had just came from the hay field when my Aunt Lynn showed up with my cousins Susie and Rebbecca.
"Us girls are going to help mom fix supper, you boys get cleaned up and come on up to the house."
Now Gramp's farm didn't have running water yet so we washed up in the shed next to the well house. I was in my underwear when Becca peeked in the door and said,
"Supper's on", she blushed as she looked at me and giggled.
"Git back to the kitchen girl" was grampa's reply, "she's a hellion, that one is", "you better watch yourself around her."
I just turned red and got dressed and headed for the house. After supper we all set around the front porch talking, listening to the radio and watching the darkness come on.
"We better head home," Aunt Lynne told the girls and started for her car.
"Can we stay tonight? Tomarrow's wash day and Grandma always needs help," Susie begged.
"We'll run the girls home tomarrow evening, if it's alright with you Lynne." Grampa stated and the issue was settled. The girl's often helped out around the place and occassionally stayed overnight. My being there wasn't going to change that but it was going to make it a little more crowded.
The house only had two bedrooms and I let the girls have one and I took the couch. It was a hot evening and after everyone settled in, I took a blanket and laid it on the front porch to get some air and hopefully get some sleep. I was laying there almost asleep when the screen door opened and Becca came out.
"Can I join you, the bedroom is too hot" she complained.
"O K, but keep it down Gramps and Grams are trying to sleep."
Becca was wearing one of gram's night shirt that was way loose and nothing else, as she crawled down beside me the hem rose up her thighs and revealed a nice set of legs. The top gapped opened and showed off her cleaveage almost down to her nipples. I laid there and groaned and tried to go back to sleep. We laid there for about an hour when Becca rolled up next to me and rested her head on my shoulder. I spooned in and put my arms around her. She turned over and pushed her butt into my groin. I gave an involuntary shudder and pushed back. My cock started rising and poking into her ass crack. Becca moaned and and reached back to stoke my hard manhood.
