We took the video from the player and followed our grandfather to his bedroom.
"Gramps," Tim said, "We want to show you something before we turn the video back on. This is a personal question; did you and Grandma ever have anal sex? That is what is coming on in the film."
"We tried it once. It was painful for her, and when I pulled out, well, I was covered in poop, not very welcome." Gramps replied.
"That is a common problem," Chris commented, reaching into a bag and pulling out some tubing. This is what Tim and I use to prepare us for anal sex. We want to show you how it works on you just in case you want to take things a step further from just a blow job. You interested?"
"I guess this is all so new; you boys know what you're doing."
"Let's go into the bathroom. We have some lube to put on your anus, so this will slide in. The bigger end is attached to the faucet; we have put an on/off valve on this other end with some extra tubing."
We attached the system together, then helped Gramps insert the tube up his anus.
"The warm water is on; the value has stopped right now. Sitting on the toilet, open the valve and let the water fill you. Once your bowels feel full, close the valve and pull the tubing out, flushing out your bowels."
Gramps did as we explained, and then we had him do it several more times until the water was clear.
"If you would have done this with grandma, she would have been cleaned out, like an enema, and you would not have had shit on your cock. We did this before we came over to be cleaned out. Take a quick shower and wash your crack, okay? We will put this in the bag and under the sink so you can use it again. Cheaper than buying enemas."
" We do not want you to feel pressured to do anything but enjoy our film," Tim informed him. "We hope you will allow us to show you how to experience the pleasure we know this brings us. You can always tell us to stop, and we will."
The film resumed; Tim was rimming Chris's ass and then fucking him with his tongue. The boys could see their grandfather starting to stir; his cock was expanding and getting firm. Both boys reached over and fondled his cock and balls as the action continued.
Pulling Chris's legs up toward his head, Tim took a bottle of lube off the nightstand and applied lube to his own cock and Chris's anus. He slowly slid his cock inside Chris. Their grandfather was at full mast.
While Tim was fucking Chris in the video, he took a bottle of lube he brought with him and coated his grandfather's hole, inserting his finger.
"Woah, that feels so hot," their grandfather said.
"Here, let me make it feel better," Chris said, lifting his grandfather's legs back and descending on him, giving him a rim job.
"Oh, yeah, this feels so good. Don't stop, lick me; I like that tongue diving in, yeah..." Gramps said.
