Two weeks later, Steph called me at the office.
"Hi Dad. I heard you are going up to see granddad this weekend. Are you going alone?"
"No, I managed to get your mother interested and maybe Josh too."
"Oh, I wish I was able to come with you. I'd love to see the look on mother's face when she sees granddad's big cock."
"Steph," I protested. "That's not the reason we're going up there. It's a weekend away for your mother."
"Sure Dad. I know what the weekend is for and I wish I were coming with you. You'll have to call me when you get back and fill me in on all that happens."
"I will."
"Promise?"
"Yes, I'll call you on Tuesday, ok?"
"Ok, talk to you then," she said as she hung up the phone.
Hesitating a little, I slowly hung up the phone and stared at it for a minute or two. My mind returned to two weeks before and I started to get a rising sensation in my groin, just from thinking about it. I smiled to myself as I sat thinking about what an erotic thrill it had been, just watching Steph and her grandfather and then watching him fuck himself on my cock, the way he did.
I tried to forget it as I made small work of tiding up my desk and getting ready to leave. As I drove home, the words from Steph's phone call came back to me and I started to get hard again. I managed to get to our street without incident and made it into the house. In the foyer, I was greeted with a stack of luggage and a smiling wife.
"We're ready, dear," she said after kissing me. "Josh is looking forward to this weekend so much, he can hardly wait to get going."
"And how about you? You looking forward to it too?"
"Yes, it will be a nice break. I just hope the weather cooperates."
I packed all the things into the car and off we went. My mind was spinning a thousand miles an hour, thinking about what the possibilities were going to be when we got there. My wife noticed my quietness and asked me if I was all right. I assured her I was and we drove on, arriving in the late afternoon.
I stopped the car and started to unpack the trunk. Josh was old enough to help but this was his first time he had ever been up here so he was off exploring before I even opened the trunk. Just as I got the last of the luggage out of the trunk, he appeared. I managed to get the bags into the house with Josh's help and up to the bedroom. My wife, in the mean time, had been exploring the house and I found her in the kitchen.
"Well, what do you think?" I asked as she turned when she heard me enter.
"I love it. It's so peaceful and open. I could get used to this very easily."
"Well, come on. Let's go find the old man and see what he's up to."
I led her out into the yard and down to the barn. I slowly opened the big door and walked inside. It was a bit gloomy and it took a few seconds for my eyes to get used to the darkness. When I could focus properly, I looked around and saw something that shocked me and yet pleased me at the same time. The old man was standing in a stall, the door open and Josh was inside with him. They both had their cocks out and were rubbing each other.
I heard a gasp behind me and realized that my wife could see them too. I quickly turned around but it was too late. She was staring into the stall and watching the two of them carefully. She had a funny look on her face as she watched them and she was licking her lips, absentmindedly. A small grin came over her face.
I looked back and Josh was on his knees, taking his grandfather's long, hard cock into his mouth. I heard the old man gasp as Josh started to suck him. I looked at my wife again. She was mesmerized, staring, smiling and softly groaning as she continued watching. When I looked back into the stall, the old man had pulled his pants all the way down, around his ankles, as Josh kept sucking him. I could hear the groans of pleasure coming from the old man as Josh continued and he held my son's head against his groin as he came in his mouth, grunting loudly as he did. I could see Josh's throat moving as he swallowed as fast as he could all the come erupting from the cock in his mouth as the old man held his head tighter and groaned louder.
"You're a good cock sucker," the old man finally said as he pulled his spent cock out of Josh's mouth. "You've done this before, haven't you?"
Josh stood up and smiled at him.
"Yes, at school in the dorm."
"You learned your lessons very well. Who says that no one learns anything at college, huh."
I heard the two of them laugh.
"Now you've made me wonder, what else you learned," the old man said, looking at Josh with a grin on his face.
Josh smiled back at him and started to undo his pants. I quickly looked at my wife and she was staring at the two men, watching Josh's body appear slowly as he continued undressing. She let out a small gasp as he pulled his underwear down and his hard cock sprang out of them, pointing straight at the old man.
"Oh, I see you've learned more," the old man laughed, grabbing hold of Josh, rubbing his rough hand up and down his length. Josh moaned and closed his eyes, savoring the feeling of his cock being rubbed by the old man. I looked again, at my wife and she was starting to breathe heavier. I could see a small bead of sweat forming on her upper lip. Her cheeks were getting redder as she continued watching her son and the old man explore each other in the middle of the stall.
I noticed the old man had grown hard again and he moved closer to Josh. He leaned forward and said something we couldn't hear to Josh and then stepped back. Josh looked around.
"I'd love to show you but I don't see anything in here we can use," Josh said, looking back at the old man. "I'd love to feel your cock inside my ass."
The smile on the old man's face grew before he spoke.
"What about your parents? Won't they wonder where you are?"
"No, it's ok. They think I'm out exploring. They won't miss me for a little while, anyway."
I heard a small gasp come from my wife and I quickly looked over at her. She had covered her mouth with her hand but was still staring at the two naked men in the stall. She looked at me and I gave her a motion to keep quiet which she did, taking her hand away from her mouth and smiling at me. I leaned closer and whispered to her.
"Watch them but you have to be quiet and not let them suspect that we're watching."
She nodded and turned her gaze back to the two men.
I watched the old man walk over and grab a horse blanket from the side of the stall and throw it onto the floor of straw, then looking over at Josh.
"Will this do?" he asked.
Josh didn't say anything but got down on the blanket, arranged himself on his hands and knees and looked back over his shoulder as the old man lowered himself between his open legs. I saw him reach between Josh's legs and massage his balls, then reach up and run a finger slowly along his crack, pushing and probing with it. I heard a soft moan come out of Josh as he closed his eyes and waited for the old man to finish his inspection.
The old man moved up and pushed the head of his hard cock against Josh's opening. Josh moaned again, pushing himself back against the old man. He grunted a little as the old man's head disappeared inside him, slowly sliding up his hole until the old man was completely inside him. I could see the old man's heavy balls resting against Josh's ass as he held on to Josh's hips, making sure that he was comfortable with his size and length before starting to fuck him.
Again my wife let out a small gasp. I motioned for her to be quiet. Her eyes were as big as saucers as she watched the old man start to pump his cock in and out of her son's ass, making Josh groan over and over again as the old man thrust in and out of him. I could hear the old man grunting every time he thrust fully into Josh and Josh would groan every time he felt the head of the old man hit the end of his canal. As they continued, their actions got more frenzied and I could tell that it wouldn't be long before one or both of them would start to come.
Just then, my wife took a hold of my arm and motioned for me to follow her. I quickly looked, once more, at the two men fucking and then turned to follow her out of the barn. When we got outside, I stopped my wife.
"What's the matter?" I asked.
"Nothing. It's just that watching those two fucking has made me so hot. I knew if I watched them any longer, I would give us away."
I smiled at her and we walked slowly back to the house, taking seats on the porch.
"Fuck, that was hot," my wife said after we had sat there for a few minutes. "Did you know about Josh?"
"No, but I knew about the old man," I said, looking her straight in the eye.
"Oh?"
I told her about the last time we had come up. She didn't seem surprised about Steph but a funny look came over her face when I explained about the old man riding my cock. We sat for a few minutes without speaking.
