As we all sat together on the sofa with grandma in the middle of myself and grandpa, we welcomed the refreshments.
Grandma piped up, "So what would you like to do today, Jakey?"
"Just relax and learn more about this new world I want to be part of," I grinned at them both with a wink.
Grandma was stroking grandpa's limp cock and now and again, juggling his balls in her hot hand.
"Do you have any more questions sonny?" asked grandpa.
"So many, but don't know where to begin really," I said excitedly.
"Well, I promised your mom and dad that we would call them and tell them when we had told you everything; they are worried how you would react!" said gramps. "Do you want me to leave anything out or add anything?"
"No! Don't leave anything out Grandpa, I don't want to live with secrets anymore, I want a full open and honest relationship with my family from now on, that can only be more loving than it already is," I replied.
"Ok I shall call them when they finish work later," he said.
"Can I ask if you and dad have ever fucked each other in the ass, grandpa?"
"No, we have fingered each other and tongued one another's butt ring but not fucked... yet. Your dad has said he would like to try but does not think he could take my eight-inch cock and I truly do not think I could take his cock with it being bigger and thicker than mine," he chuckled. "But to be honest we all like to watch guys fucking each other in porn, especially when women are involved also."
He leant over and kissed Grandma on the cheek.
"Wow, you watch guys fucking?" I must have sounded like an excited child because they both chuckled.
"Yes, as I said before we have quite a selection of porn, covering just about every sort of pleasure people can share," said grandpa.
"Could we watch some?" I asked nervously, just as grandma's free hand came to rest on my limp cock.
"Of course, do you want just guys or maybe a mixed film?" grandpa asked, as he lifted himself off the sofa and his erection stood proud; he walked over to a wall mounted cupboard where he kept his library of porn dvd's.
"Mixed I think, for now anyway," I responded.
Grandma lowered her head and took my soft cock in her warm mouth, swirling her tongue around it while playing with my ball sack. Grandpa inserted the dvd into the machine and sat back down.
He started the film with the remote; he then started rubbing grandma's butt cheeks as she sat sort of side on while sucking me. Grandma had my cock rising to full splendour as she expertly sucked, licked, and stroked my cock from tip to base, even cupping my balls and giving a gentle squeeze.
I looked at the tv - the film was set in what I assumed was a Roman hall of some sort, as all the people were wearing togas or just a short wrap around their waists.
Servants were serving drinks to those sat on cushions around the room. In the centre of the room, many cushions were scattered and naked bodies of men and women in various sex acts seemed to be putting on a show.
I could feel my cock pulsing in my grandma's mouth and her saliva running onto my balls and round to my ass crack, I then felt one of her fingers gently stroking the area between my scrotum and the start of my hairy ass valley. It felt really nice, so I shuffled myself towards the edge of the sofa.
Looking back at the screen, I saw a man wearing some sort of crown with one hand feeling up the inner thigh of a serving girl and his other hand stroking the cock of a young man who was serving grapes from a gold platter. The young male had neither pubes nor chest hair, but a nice long thin cock that stood tall from the attention it was getting.
Grandma slightly adjusted how she was on the sofa and started to let out little moans. Grandpa sucked his fingers then moved them to her butt; I imagine he was playing with either her pussy or ass hole.
"Does fucking an ass, feel different to fucking a pussy or just the same?" I asked.
"A pussy gets wetter, but an ass seems to grip tighter," Grandpa said, as if this was just a normal everyday conversation. "But both feel fucking great, and it is nice to shoot your hot seed into them both equally," he continued. "I'm sure your grandma will let you try her arse sometime soon sonny," he winked.
