In this third installment of the story, Grandpa Ed has now seduced his granddaughter Lindsey into going all the way, although it's not fully clear to him who had actually been the one seduced.
Now that he's turned Lindsey on, he finds he can't turn her off.

Chapter One: Afternoon daydreaming.
I leaned against the shovel I had been using, taking the opportunity to wipe my dripping brow, and happy for an excuse to take a breather from working in the hot sun. Being 61 was never more obvious to me than today. Everything ached. My back protested every movement, my legs felt heavy and sore, and my shoulders throbbed as well.
All of that discomfort paled in comparison to the way my cock felt. Raw and aching, it had been given such a thorough workout in the few days Lindsey had been around, that it felt like it weighed a ton as it dangled loosely in my boxers.
I didn't really want to work in the yard in the heat of the day, but I knew that if I went inside, Lindsey would be all over me, wanting to either fuck me or suck me. Even my tongue was worn out in my efforts to keep Lindsey satified.
It was a great predicament to be in, I thought to myself as I went back to work. The lithe and lean teenager was crazy about me for some reason, and I knew that despite feeling like I was fixing to die right now, come evening I would be ready have another go at Lindsey.
Eventually, I needed to go to the bathroom, but figured that it would be best to go behind the barn to do my business, rather than risk a Lindsey meeting. Being out here in the middle of nowhere, privacy was not an issue, so I walked out back and pulled out my trusty member.
I let it hang out, letting the breeze cool it off, and finally gave it a tug or two to get the process started. Keeps taking longer all the time to get the pee flowing, or so it seems, but eventually the faucet got turned on and I began watering the weeds. After what seemed like an endless stream, the flow became a trickle, and I gave my cock a few shakes to end the process. As I did, I heard a giggle from the side of the barn. Lindsey.
"I saw you peeing, Grandpa," Lindsey said as she came out into full view. "Naughty Grandpa."
"Well, nobody out here to see," I said, feeling my face redden as I quickly put myself back in my pants. "Except nosy young ladies."
"That was neat to watch," Lindsey said.
Lindsey was wearing a tank top and jean shorts, and as she came over toward me, began undoing the clasp on the shorts.
She was wearing nothing underneath, and her flaming red bush was even more dazzling in the bright sunlight. Lindsey kicked the shorts off, and to my shock, spread her legs apart.
Lindsey laughed as I jumped back when she began to urinate right then and there. Pee gushed from between her legs, spraying the ground as I stared in shock at the sight of her going right in front of me. She seemed to enjoy my stunned expression, and although I was in shock, I didn't stop looking either.
"Like to watch that, Grandpa?" Lindsey said as she reached over and grabbed her shorts off the ground. "Gotta go in and wipe."
As she walked bare-assed toward the house, her ghostly pale butt cheeks wiggling a little as she moved, Lindsey stopped briefly to invite me to come inside with her to help with the task, before disappearing from my sight.
"Good grief," I muttered to myself as I waited a few seconds before returning to my shovel, not quite comprehending what had just gone on while acknowledging my confusion was accompanied by my cock stirring slightly.
Chapter Two: Dinner with Lindsey.
I managed to avoid Lindsey until late afternoon, and to my delight she had gotten dinner started when I went in for the day. She had made spaghetti and meatballs, and while I had planned to take a shower before eating, the aroma drew me in.
"Guess I'll hold off on my shower," I said as she began setting the table. "It smells great."
"Just about ready too," Lindsey said. "You can take a shower after dinner, okay?"
"Sure thing," I agreed.
Dinner was uneventful, unless you want to count Lindsey playing footsie under the table with me. The foot rose higher as her long legs allowed her to let her foot slide up to my crotch for a little poking.
After we ate, Lindsey did the dishes. I usually helped her with the task but that inevitably got us rubbing up against each other, and before you know it we were screwing.
I needed a respite. These few days with Lindsey had taken a toll on me. Unlike Molly during her time with me during the previous summer, once was not enough for Lindsey. What ever happened to the shy girl that arrived with her parents? The one that pawed at the carpet and wouldn't so much as look me in the eye?
This Lindsey was positively feral, and now here she was again. She had finished the dishes and had found me in the living room, smiling and looking like she had something up her sleeve.
"Want some dessert, Grandpa?" Lindsey cooed.
The after dinner treat was not on any restaurant menu I'd ever seen, as what the teen was offering was her titties. Lifting her blouse up brazenly, Lindsey exposed her braless breasts to me, shaking her upper torso so that the little boobies wiggled from side to side. Those nipples - those incredibly puffy aureolas, never failed to arouse me. She knew how to get my attention, and I felt some vague stirrings below the belt as I watched her show.
"Whatcha say, Grandpa?"
"Say!" I said, as my eyes caught a glimpse of the hair under Lindsey's arms as she raised them while lifting her shirt. "Weren't we going to give you a little smoothing?"
"OH YEAH!" Lindsey exclaimed with delight. "Yes! What do we need?"
"Get a bowl with warm water in it, and I'll meet you in the bedroom," I instructed Lindsey before heading into the bathroom for the razor and cream.
This would give me a little time to get the blood flowing again, I figured to myself. Maybe kill enough time so that I wouldn't have to endure trying to get my 61 year old cock up for multiple performances. Oh, to be young again. Where had I wasted my youth?
Ethel, I was reminded by the picture of us in the hall. The cold fish that had shut me off for the last few years of her life so that she persue her ultimate love. Bingo.
Now this was the life, I reassured myself as I came out of the bathroom, trying to get that picture of Ethel out of my head so that I could concentrate on a much more pleasant sight.
Chapter Three: Shaving Lindsey.
"Before you start, Grandpa, I want you to do something," Lindsey said after I positioned her on the bed the way I wanted her. "Take off your pants."
I undid my belt and let my trousers drop to the floor, and then tugged the boxers down as well, kicking the tangle of clothes off to the side. Feeling stupid with just my shirt on, I took that off as well, leaving both of us naked.
