The next few days with my Grandparents were a whirlwind of nudity and sex. None of us would wear any clothes and my own all-over tan started to darken. The lack of clothes being worn by all not only saved Grandma from doing laundry, but also opened up many opportunities for fucking and sucking. Every morning, it seems, either Grandpa or I, or both would take Grandma over the kitchen table. We knew we would end up fucking sooner or later so doing it first thing worked out well. It allowed me the opportunity to get my chores done after breakfast so I could spend the rest of the day goofing off or having even more sex. I am still surprised at how much Grandpa and Grandma fuck. I am 18 and these 60+ year olds have more sexual stamina and energy than me. I figured for sure that Grandpa must take Viagra but they both swear that his hard-ons are natural. At one point, Grandpa offered his ass to me to fuck. I don't mind sucking his cock but something about anal sex with another man still turned me off. I declined his invitation. On the other hand, when Grandma offered her ass to me, I accepted her offer. Her asshole is nice and tight and grips my cock nicely. Grandpa and I even did a DP on Grandma. Grandpa filled her pussy with his cum and I filled her ass with mine.
One morning at about 11 o'clock, I had just finished my chores and was heading up to the house. A black Jeep came driving down the driveway toward the house. I was naked and ran for the back door. Charlie (the dog) barked a few times and met the Jeep by the front porch. His tail was wagging so I figured he must know whoever it was. I watched from the front window as Grandma walked out onto the porch. Grandma was still naked.
"Good Morning, Sally!" she called toward the Jeep.
The passenger door opened and a lady got out of the car. The driver's side was empty.
"Hello, Marge!" the lady responded, "I have a package for Harold."
The lady was OK looking. She was mid to late 30s, average height and a little overweight. She had long auburn hair and a friendly smile. She was kind of pretty in a 'natural' way. She was carrying a box and some letters. Sally was the mail carrier.
"Porn or toys?" Grandma asked.
"Porn is my guess." answered Sally as she walked toward the porch, "Plus he got his new 'Penthouse' magazine."
"Well, that ought to keep him busy. At least for a few hours." Grandma joked as she took the stuff that Sally was carrying; "Do you have time for coffee?"
"Sure. It's a pretty light day today," said Sally.
They both went into the kitchen. Sally sat at the table and Grandma put the box and the rest of the mail on the table. Grandma poured them both a cup of coffee and called for me.
"Jake! Come down here. I want you to meet somebody." She yelled toward the stairs.
"I'm right here, Grandma!" I told her.
I was just in the other room and was only a few feet from her. I startled her a bit, but she recovered quickly.
"Come in here and meet somebody."
Grandma grabbed my arm with her free hand and gently ushered me into the kitchen. I was still naked and tried to cover myself.
"Oh! Stop being shy!" Grandma said. "Jake, this is Sally. Sally, this is my grandson Jake. Sally delivers our mail."
"Hello!" I muttered.
"Grandson?" Sally puzzled briefly before lighting up "Oh! This must be Patty's oldest boy. Nice meeting you!"
Sally stretched out her hand in greeting. I took her hand in mine and shook it quickly. I used the hand that I had covered my dick with and Sally got an eyeful. I tried to let go, but she kept shaking.
"VERY nice meeting you." She added. Her smile broadened.
"Jake will be staying with us while he goes to college here in town." Grandma chimed in. "and he is adapting to our lifestyle quite nicely. Aren't you, honey?"
"Umm. Yeah. I'm trying." I answered.
Sally let go of my hand, but I decided not to cover up this time. Grandma motioned for me to sit and visit with them. I sat in a way that allowed Sally to keep looking at my dick, if she wanted. She looked away often in conversation but always looked back.
"Where is Harold?" Sally asked
I hadn't seen him all day. Grandma and I had fucked and had breakfast without him that morning.
"He went to town early." Grandma responded. "He'll be back later."
I could tell that Sally enjoyed looking at my cock. I stroked it a bit to get it hard.
Sally looked at me and asked, "You know, I only have a few minutes left before I have to go. You just planning on teasing me or can I suck you off before I leave?"
"WOW! Is everybody around here so forward and blunt?" I thought to myself.
"Please do." I answered her.
Sally looked at Grandma, smiled and then got on her knees in front of me. She was good but still not as good as Grandma. Sally spent a lot of time stroking my balls and licking and sucking them. I really enjoyed all of that. She really seemed to get into it as well.
Grandma moved into Sally's chair so she could watch. While Sally sucked my cock and balls, I watched Grandma masturbate.
"He already came in my pussy once today" Grandma bragged, "But I know he has a nice load of cum for you too."
Sally was moaning and her sucking intensified.
"Damn!" She said, "If I had more time, I'd let him fuck me and cum in my pussy too."
Watching Grandma acting and talking like a slut again helped me get off. Sally was a good cocksucker too. Both of these factors helped me cum.
