The thought of Abby being filled with my cum and keeping it inside her was, well, too hot a statement to be passed up by Stefanie.

"How much?" Stefanie asked.

"Wasn't it about 6 or 7 times last night and this morning?" Abby asked me.

"Three times this morning, four last night and overnight," I said.

"You've been a busy boy!" Stefanie said to me. "I knew your balls had to able to pump it out if you were satisfying all these girls you had here last time."

We sat there quietly for a moment before Stefanie asked "In your pussy, in your ass, or both?"

"All in my pussy," Abby replied with a smile. "We cleaned my ass out last night and this morning with several enemas so he can fill my ass tonight." Abby seemed particularly happy to share this with Stefanie. Stefanie got up from where she was sitting in front of us. I noticed her nipples were erect when she stood up. I wondered if her pussy was getting wet talking about this. She picked up her towel and placed it beside Abby so that Abby was in the middle between us.

"Do you mind talking about this?" Stefanie asked. "Woman to woman?"

"I'm okay with it," Abby said. "I won't answer if I feel too uncomfortable." Abby asked me if I was okay with that. I moved my position a bit so I could here the questions and the answers. I told Abby I didn't mind. Stefanie already knew the basics about our background

"Does he have a nice, big cock?" Stefanie asked.

"I think so," Abby said. "He certainly fills me. Hon, can I show her your pictures?" Abby asked. I told her she could and I handed her wallet to her. She opened it and there were the pictures of me at my brass bed (the ones I had originally given to Catie and later transferred to Abby).

Stefanie looked at the pictures with my erection. "Oh My God, Gary how big is that thing?" People looked up at Stefanie's exclamation and question. She glanced up and realized that people were looking at her/us. "Sorry," she said quietly to us. "It looks huge," she said quietly.

"It isn't. It's only about 7-1/4 to 7-1/2 inches long when I'm ready to cum. Maybe 1-3/4 inches wide, 2-inches max," I said.

"How do you know that?" Stefanie asked. "Do you go around measuring yourself?"

"I am an engineer, you know? I've got to know this kind of stuff. No, actually, my ex-wife did when we met...lots of times. She wasn't a virgin when we met and she told me that I had the largest cock she'd ever taken. So, she had this tape measure she liked to use, sometimes stopping me just before I was ready to cum, and then we went and looked it up in the library after she'd averaged some of the numbers. I know I'm above average in size and that I'm well into the 90th percentiles in length and girth. But I'm not huge."

"He gets really big when he gets close to cumming," Abby told Stefanie. Stefanie looked at me. All I could do was shrug.

I looked up and saw Steve making his way towards us along the water's edge. I stood up to shake his hand and we greeted each other. He reached out to Abby who was still sitting next to Stefanie. "Sorry, I remember you but I don't remember your name." he said.

"I'm Abby," she said.

"Abby, yes. Hi, Abby!"

Stefanie pointed to their blanket and stuff so that Steve could set down the bag and cooler he was carrying. "Come back here when you drop the stuff, I want to show you something."

I sat back down. Steve was away for only 20 - 30 seconds before he returned with a towel that he dropped onto the sand next to Stefanie. She patted it and he sat down.

"Stand up, dear," Stefanie said to Abby. Abby got up.

"Now turn around and bend over to show him your plug." Abby bent over slightly so that her butt plug was plainly visible to him as he was sitting looking up at her ass.

"That's really nice," Steve said. "Adds a nice touch to her ass," said to Stefanie.

"Now turn around, dear, and show him the other one." She turned around to face him. Since he was sitting, he was looking up at her pussy. Sliding her hands down the front of her hips to the inside of her thighs, she spread her vulva and labia and he could see the other plug in her pussy.

"She came out here with seven loads of his cum plugged inside her." Stefanie didn't elaborate where the cum was plugged.

"What? Are you shitting me?" Steve said to Stefanie.

"And look at these," Stephanie said, handing him the photos from Abby's wallet. He looked at them, looked up at me, back down at them, and then back up at me like he was trying to make sure that I was the same person as was in the photos. "You've been putting that into her and her friends?" I nodded my head yes.

He turned to Abby, who had sat back down, "and you lost your virginity to him and taken all of that?" Abby nodded yes. "In your mouth, in your cunt, and in your ass?" Steve asked. (Cunt is a word that I rarely use because I tend to see as a vulgar description. But it's the word he used).

"Not in my mouth. He's too big for my mouth. But yes, in my pussy and my ass." Abby said something to Stefanie but I couldn't hear what she said. Steve let out a low whistle.

"Dude, you are my hero! Actually, you're both my heroes," Steve said. He handed the photos back to Stefanie who handed them to Abby. She gave the wallet back to me and I stowed it back in the bottom of one of our bags.

Steve asked if the other girls were going to be out here today.

"Maybe my roommate," Abby answered.

There was a little more chatting between the four of us.

"Want to go get in a game?" Steve asked referring to the volleyball game(s) going on. I looked at Abby. "You go ahead," Abby said to me.

"I'll take good care of her," Stefanie said. I wasn't sure what she meant. "I'll be right over here if you need me," I said to Abby. Abby smiled and winked at me. I took the wink as meaning that she always needed me.

Steve and I got up and headed to the volleyball area where a game was already in progress and another one was about to begin. He dropped his towel on their blanket and as we headed towards the volleyball area, he draped his arm over my shoulders.

"Man! I had no fucking idea!" He didn't elaborate on what he referring to. I assumed he was talking about my cock size in the photos.

"And you were screwing her sister at the same time, too. Right?" he asked.

"Yes, the one that died," I replied.

"Such a waste," Steve said. "Can I ask you are personal question? And I don't mean any offense," he said. I remember thinking "we're already into personal questions."

"Sure," I replied. By this time we were standing on the sidelines while the game played on.

"What is that like?" Steve asked. I asked what he meant and he clarified that he was asking what is it like to be in bed with two sisters at the same time.

"It was a little weird, at first. I've been in bed with two women before, but they were friends, not related to each other. Here I was in this incredibly wonderful relationship with Abby's older sister and I'm being offered the chance to sleep with Abby, a virgin at that, with her sister there with us; It was like I was giving lessons. First, by Abby watching us, and then by Abby trying for herself while her sister was there to talk her through her surrendering of her virginity to me."

"That had to be weird," Steve said. "Fucking her younger sister and taking her virginity right in front of her."

"Not as weird as I thought," I replied. "I didn't know it when we met, but her older sister, Catie, really had a thing for watching me fuck other women. Abby's a little like that, too." I paused for a moment to decide how much I really wanted to share. "Eventually, it was a mix of sleeping with them individually and when the three of us slept together. And they both knew when I was sleeping with the other sister. But Catie was my main *squeeze,*" I said.

"And now you have Abby," he said.

"And now I have Abby," I echoed.

"No offense intended, but as an older guy, what's it like to be fucking that sweet, young ass of hers?"

I looked over towards Abby and she was laying on her stomach, her head oriented to our direction. She was propped up on her elbows and forearms talking to Stefanie who was laying beside her in a similar position. The sun was highlighting the curve of her back, her hips, and her ass. I imagined from the other direction that one could see the butt plug tucked firmly in her butt cheeks. Yes indeed, my cock would be inside her fucking that sweet young ass of hers later today and tonight. With that thought, my cock began to stir as I felt a wave of pleasure wash through me and through my cock and balls. I realized that I couldn't dwell on these thoughts, lest I be walking around with a raging hard-on. I was probably already starting to develop a drop of pre-cum.

"It's simply heavenly. It's like watching her explore her sexual nature while I'm being a guide and a teacher, to be there to try new things or expand what she's already experienced. Our lovemaking can range from intense and frantic to slow and unhurried...there's always the next orgasm for both of us."

"I love cumming inside her and staying inside her after I cum. She loves feeling me cum inside her, knowing I'm shooting my cum deep inside her and then holding my cock and my cum in her, too. She's told me that it's so unfair that she can have orgasm after orgasm in almost a continuous wave and stream, and we get ours one at a time. She's discovered the paradox of wanting to feel my limited number of orgasms while knowing that sensation of feeling me cum often triggers her own orgasms thereby distracting her from feeling mine. But from the very first time, she's always loved to feel me cum in her."

"It's definitely NOT ABOUT GETTING IT OVER WITH so we can move on doing something else," I said. "And she doesn't have all the baggage of a bunch of previous lovers and what they did and did not do to, for, or with her," I said.

"Has she slept with anyone else," Steve asked. I remember thinking "like you think you have a chance?" or something equally as snarky, as I felt a degree of protectiveness kick in.

"Yes," I said and then added "But since last October, when we first started sleeping together, I am her only repeat lover."

Immediately after I answered that question, the previous volleyball game finished and we stepped into boundaries of the sandy court to begin warmups for the next game. It was "court possession" as the losing team gave up their position on the court. If the winning team had people who retired after the game, they had their choice of new participants to add to their team.

The team that I was on won the next game, and the game after that. Between games, I went back over to our cooler to get something to drink. After we won the second game, Abby and Stefanie came over to the side of the court to watch "their guys" play. Seeing Abby beside the court, standing there with Stefanie, was incredibly distracting; looking at the way the sun cast shadows under her breasts, thinking about the cum still inside her. When I rotated over to the side of the court where Abby was standing, I would grab a quick drink, a quick squeeze of her, and a quick kiss.

"Hey, what about me?" Stefanie protested.

"That's what your guy is for," I retorted. I was going to say something else, but left it at that.

Our third game went into overtime as we kept trading points once we got to 21-all. We were finally beaten though, I don't recall how many extra points had to be played (if I had to guess it was 33-31 or 35-33). It was a good game and I was ready for a break and a dip in the water. Abby wanted to take a walk. I asked them to keep an eye on our stuff (not that anyone would necessary walk off with it). Everyone pretty much knew who was around them and what belonged to who. I grabbed a towel and Abby walked towards the river side of the island.

During low water, like it was today (and had been the previous week), you could walk a long way around the island and certainly to the upstream tip of the island. Generally, it was sandy on the river side of the island, though there could be mudflats. And there was often tree debris that floated down the river and got caught on the shores of the island. People who came to the island by boat tended to anchor on the upstream part of the island and come ashore and were usually not part of the "usual crowd" that accessed the island from the parking area. But there were usually only a few pleasure boats on the river accessing Sand Island and the nude beach most days. There were probably half a dozen visible this day.

You did need to mindful if the river level was rising because of water release from the upstream dams, but it usually was not a rapid rise in water level (or at least I never saw a rapid increase in the water level). And so, we walked away from the crowd hand-in-hand or with our arms wrapped around each other's waist. Abby's hand would occasionally slip down to my butt and give it a light squeeze. I was doing the same. It was erotic to be walking nude like this in the sand. I liked the feel of the muscle power that was applied to walking in the sand.

Once we had crossed over to the river side, it was pretty much a straight walk along the north shore of the island. On the other side of the river was the Washington shoreline.

In addition to the pleasure boat traffic along the river, there were also large river barges that travelled up and down the river. I imagined that the crews of the tugboats had their binoculars out looking at whatever nude beach goers were visible as the want by this island or the other nude beach further down the river (Collins Beach on Sauvie Island). The extent of sandy beach narrowed in a few places and we had to go around some beached logs but there weren't many people out here. As we walked along Abby told me that talking with Stefanie got her so hot and horny, and then standing beside the volleyball court just made her hotter as she watched my body (and my cock) bound around as I was playing on the volleyball court.

"I want to fuck you so bad," Abby told me as we got further down the Columbia River side of the island (technically the Columbia River came around the south side of the island, too, and was also the Columbia River). I asked her about talking with Stefanie and what got Abby so hot and horny. It wasn't so much about Stefanie telling Abby about her experiences (though there was some of that). It was being able to tell someone else, in this case telling an older adult woman, about the things we (Abby and I) did, the things she (Abby) felt when we were together. It was sharing and baring her soul to another woman who didn't/wouldn't condemn Abby for being involved with an older man or being involved with her sister in the threesome that we had.

"Like what?" I asked.

Abby started a recounting of some of what we would consider "the best of..." while we continued walking down the beach. She loved being able to lay there and tell Stefanie about what we did, what our sex life involved, how she felt when she and I were together. I gathered, from what Abby told me, that there was validation for what Abby felt and experienced from the perspective of a woman who had lived twice as long as Abby, and had her own lifetime of sexual experiences from the age of 15.

"The more we talked, the more I wanted to run over, throw you down on the sand, and fuck you in front of all of those people!"

"That would be fun...and entertaining," I said.

We had walked, probably about a half-mile and were well away from the three boats that were anchored in the shallow water on the downstream side of the island. There was a narrowing of the beach where the combination of elevation rise to the trees and higher water could make passage more difficult. On the other side of this narrowing, it flattened and widened out again. Down on this end of the island, you were far more likely to find boats anchored and people from those boats on the beach on this end of the island. But here, Abby and I were relatively alone. We could see a couple on the beach behind a good ways behind us and nobody on the beach in front of us.

Abby's nipples were pointy and erect while we were walking and she was talking. It wasn't a chill off the water that was causing her nipples to be erect. Behind the plug in her pussy, I suspect that there was a huge dam burst of my cum and her juices just waiting to be released. I was getting hard listening to her as we walked down the beach which just magnified our desire.

We reached a point where a large, debarked, and 'bleached" tree trunk lay across the beach. To go around it, we needed to step near the shallow water at the river's edge or walk towards the tree line where the base of three lay. Abby stopped before we turned one way or the other to go around it. She reached for my other hand and I put down the bag with the bottles of water and drinks we had. The towel was still draped over my shoulder. She held my hands and didn't say anything, just looked at me for a few moments and then reached up and draped her arms around my shoulders and we drew each other close.

"I want you to fuck me," Abby said. "Right here, right now on the beach! I need you inside me, so bad." This was definitely "the horny Abby" speaking.
