Dinah asked if anyone had a problem with pizza. None of us had, so she ordered a bunch of them. As delivery would take a while, we all went into the bathroom together and tried to squeeze into the shower. That was fun but it didn't work, so we split two and two. We tossed up a quarter to decide the pairs, and Sally and I were together. Dinah and Liz went first and made the shower session short, but Dinah managed to make Liz get off despite that.

As she and my sister were drying off, Sally and I had our shower, and Dinah hurried downstairs to be there for when the pizzas came. Liz stayed, to watch.

"Do you think your mom will answer the door naked?" I asked as I soaped up Sally boobs and she worked my cock up to a stiff state.

"Wouldn't surprise me, " Sally said. "You know, it was so hot seeing you fuck my mom. And your sister. You fucked your own sister!"

"I'm up for more, " Liz said. She got up and listened at the door. "Pizza arrived. I'll see you downstairs."

Sally and I didn't waste much more time in the shower, but she did offer her behind to me so I could do a quickie from behind. She was curious how that felt, because she'd seen Liz and me do that. She definitely approved of it, and we both said we were stupid to stop, but the pizza was waiting.

*

All the pizza was laid out on the table outside. When I sat down, I noticed how nicely secluded the spot was. My heart pounded for a while when I became aware that neighbors might have seen our sexual actions, and I hadn't even thought about that. Certainly Dinah wouldn't have let us do that if there was a risk of being seen. I didn't see any houses left or right, so we should be fine. And it should be, as we were sitting outside with nothing on.

Sally said she was glad she and Liz had talked during the party. "Now I know how John's cock looks when it's big." She grinned as she shoved some pizza in her mouth.

"We all do, " Dinah said, "and I think we're all happy with it." She sat next to me and reached out, wrapping her warm and greasy fingers around my cock. It didn't take long before I got hard again. "Oh my, now look what I've done." She laughed and looked at Liz and Sally. "Any volunteers to lick that clean?"

The two exchanged glances, then both tossed their bit of pizza on the table and came over, squatting down with me and taking turns at licking my cock.

"Good girls, " Dinah said as she turned to me. "I think they are cleaning it up so I can sit on it soon. I hope you're fine with that."

I grinned. "Of course. As long as the chair holds us."

Sally got up and pushed Liz to the side. "I'll test that."

"Hey!" Liz said, who scrambled up.

By that time Sally had turned around and sat down, grabbing my cock and guiding that into her pussy. I slipped in just like that, which made me wonder if Sally had ever been not wet since we got out of the shower.

"I love this, " she announced as she bounced up and down a bit.

"You're gonna pay, " Liz said as she came closer. She grabbed Sally's head and pushed it down to her crotch. "Lick me, you cock stealing little bitch."

Dinah laughed as she saw it all happen, and encouraged Sally to give my sister a really good licking. "Deep and thorough, girl, one she'll remember for the rest of her life."

Sally did her best because soon Liz was groaning and almost doubling over. I was stunned to see so much ecstasy in her face.

"Oh-my-god oh-my-god, " my sister suddenly moaned as she almost doubled over on top of Sally. She was bucking and jolting while Sally yelped. It was clear that the girl who was riding my cock had managed to make Liz get off as she stood in front of us.

Liz staggered back to her chair and just sat there, bent over, as her orgasm kept going.

Sally sat up and looked back at me. "I got her good, huh? You have a very tasty sister, John."

"Let me tell you that my daughter is very lickable too, John." Dinah got up and knelt down, and to my surprise she pushed Sally back against me. Then, while my cock was still inside her daughter, Dinah started licking Sally's pussy, occasionally giving my cock a lick too. "Come on, girl. You can fuck while I do this, " she encouraged her daughter, but Sally was breathing hard and unable to act.

I reached around Sally, put my hands on her boobs, and started jerking my hips up a bit, so I was sort of fucking her while her mother licked her. It was crazy to think off, and at the same time it was incredibly sexy to know it was going on, even when I could see it.

Dinah managed to get Sally off while I was still humping her. Sally slammed back into me as her orgasm crashed into her, and then I got off as well. Hard. The knowledge that my own sister and also Sally's mom were watching us was so hot! Her pussy squeezed hard one last time, and my cock flopped out of her. I felt her panting as my hands were still on her boobs, and I kept them there until she'd calmed down a little.

"I never had one like that, " Sally said once she was able to talk again.

Dinah had sat down again and grinned. "I think we all could tell."

Sally slowly got up, turned and leaned over to kiss me on the mouth. Her tongue pushed between my lips and played there for a while, as my cum slowly seeped out of her pussy, much to Dinah's delight. "Thank you, John, " she said.

"You're welcome, " I said.

Before sitting down, she picked up a slice of pizza. "I need this now."

Dinah looked at each of us and was clearly happy. "Yes, thank you for that show, John. Aren't we all having a good time, " she said. We all nodded.

"I'd never thought this would happen, " Liz said, also reaching for a slice of pizza.

"I just hoped for it, " Dinah said. "After what Sally told me, it sounded enticing. And that came true more than I'd wished for."

"Oh..." Liz looked down at where some tomato sauce had splattered on one of her boobs. She looked for a paper napkin but I was faster.

"Let me, " I said as I got up. Slowly I licked up the sauce, making sure I hit her nipple a lot.

"Now that's service." Dinah laughed. Carefully she smeared some sauce on both her nipples. "Care to service me too?"

"Me too!" Sally grabbed a new piece and slathered tomato sauce all over her boobs.

Liz and I laughed, and I got up to deal with all the boob-ware and the tomato sauce on them. Dinah pulled my face between her boobs and rubbed them over my cheeks, after which Sally tried to do the same, but her boobs weren't big enough for the same effect yet. I had fun licking though, and kept sucking all the nipples that were available. My sister joined the party, because she didn't want to be left out.

I had no idea how much it would excite me to suck and lick nipples. My cock had grown to its full extent again and Dinah was fondling it, while she said it was hot to see me sucking my sister's nipples. I had to admit that it was fabulous. Perhaps because it was so wrong and we could do it anyway.

In the end all boobs were tomato free, but my face wasn't, so Sally and Liz licked my face clean while we were standing up. I had my arms around both of them, my hands resting on their butts. Dinah had taken a mouthful of my cock again. This was the best pizza party ever, and I told them so.

Dinah let my cock slip and held it in a hand as she looked up at me from her chair. "We can do it again. Anytime."

Sally and Liz decided my face was clean enough so we all sat down.

Dinah admitted that she was a bit tired. "It's been a long time that I had this kind of sex. And then so much of it too."

I grinned. "Glad we could do that for you."

"We did it for all of us, " Liz said. She wiggled a bit in her chair. "My pussy feels..." She frowned. "Very well used."

"Does it hurt?" Dinah asked.

"Nah. Just... well used. I mean, John fucked me quite a lot, and Sally had her fingers deep inside me for a while too."

Sally and her mom nodded, and admitted that their pussies also were 'buzzing' after all the sexual activities we'd engaged in.

"How's your cock doing, John?" Sally asked.

"It feels fine, " I said, "but I can tell it's seen a lot of action."

"Perhaps best that we take it slow until we go to bed, " Dinah suggested.

Evening arrived and so had a distinct chill in the air, so we moved inside where the temperature was a lot nicer.

"John, you go sit on the couch, " Dinah said. "I want both girls sitting in your lap. One on each knee. You think you can handle that?"

I was sure I could, and I liked that idea. Once I sat, Sally and Liz both were quick to sit down on my legs. It was a bit of a struggle where they should put their legs, as those also were between mine, but we worked it out.

Dinah looked at us from a chair opposite the couch. "That looks so hot. My little girl and her two friends. Nekkid as jaybirds." She instructed me to put a hand on their boobs, so I slipped my arms around them, under their arms and that was that.

"It's nice to feel the difference, " I commented as my cock was rising up again. Liz asked which boob was better, hers or Sally's. I couldn't answer that. "They're just different. Yours is bigger. Hers is firmer." I ran a finger over their nipples. "hard nipples everywhere."

Feeling both of them leaning into me was totally intense, and it got better as first Liz and then also Sally started playing with my cock. I returned the favor by keeping my fingers busy with their nipples. It was obvious that they liked that very much.

Dinah also liked what she saw, because she had her legs wide apart and slapped several fingers into her pussy while she massaged her boobs in turn.

Liz turned to me and whispered, "I wish I had a few pictures of us like this."

"Are you serious?" I whispered back. The thought hadn't appeared to me but the idea immediately sounded appealing. "Me too."

"What me too?" Sally had heard that, so Liz told her what she'd just told me.

"Oh my god yes, that would be so hot, " Sally said. "But I'm a bit scared with that. You know, with the internet and all that."

Dinah had listened to us. "I think we can do that, " she said. "I can take some pictures and send those directly to your phones. No internet and stuff needed. On the condition that we all get some pictures made with us. And a few with all of us, with the timer."

Liz and I were immediately in favor. Sally still frowned a bit and needed some more encouragement, so in the end she agreed.

Dinah took her phone and snapped a few pictures of us, which she showed. They were actually pretty good, although it was really weird seeing myself like that. With my sister. Having Sally in my lap wasn't so weird. It surprised me a bit how I felt, because I'd been fucking my sister with gusto a lot already.

Dinah got down on her knees and took some more pictures, directing Liz and Sally on how to sit, telling them to grab my cock and to kiss me on the cheeks at the same time.

"Now me, " Dinah said, handing her phone to Liz, who got up. Dinah sat next to me, on her knees, and pulled my face between her boobs, while Liz took pictures. Next Dinah leaned over and stuck out her tongue. Liz made pictures of how Sally's mom licked my cock, took it in her mouth, and how she shoved a hand between Sally thighs.

After that, we went wild. I took pictures of the three women together, doing all kinds of stuff to each other. Sally then suggested I should lie on the floor, one of them would sit on my cock and the other one on my face, and then, after some pictures, they'd all change places so they all had had been in both spots on top of me.

By then Dinah had also brought out wine and beer, which made us a lot more relaxed. And after getting off a few times, each of us, also tired.

After the insane photo shoot Dinah did as she'd promised. She sent all pictures to each of our phones, and we all promised to safeguard those shots so none of them would leak out into the world.

Not all the pictures had turned out great, but we kept them all. They were a very sexy reminder of this crazy day.

By then we had to figure out the sleeping arrangement, and the problem was that all three women wanted me in their bed, but none of the beds in the house were big enough to hold all of us.

"That sucks, " said Sally as she toyed with my cock. She was sitting in my lap. Then she looked up. "I got it. Camping!"

"Camping?" Dinah, sitting next to me with Liz in her lap, looked puzzled.

"We still have that huge air mattress, " Sally said. "We could all sleep on that, here in the living room."

"God, that thing must be leaking everywhere, " Dinah said, but she agreed that it was worth a shot, so she made Liz get up, who sat on me again, and walked off.

A few minutes later Dinah called for help. She'd located the air mattress and needed some assistance in dragging it to the living room. I went to help her while Sally went looking for the pump to get the mattress ready for its task.

The mattress was still in good shape, which was a good thing. We all took turns in pumping up the mattress, during which we took pictures of each other again, and soon the sleeping space was done. Sally went to get some sheets and recruited Liz to come and help with some pillows, while Dinah distributed the pictures to all of us again. It was so arousing to see those shots arrive on my phone.

At some point Dinah knelt down and started sucking my cock, with the excuse that I was dripping on the floor, which made me laugh.

Finally the big bed was ready. Then there was another problem. Who would lie where? With three women, I couldn't lie in the middle, which was considered an issue. In the end we decided to just lie down and let things take their course.

The lights went off and semi darkness engulfed us. I lay between Dinah and Liz, which felt incredible.

Dinah said she'd never seen a brother and a sister fuck each other, and definitely not as much as we'd done that day.

I reached over Liz and found one of Dinah's boobs, and gave it a good squeeze. "I had never thought that I'd fuck the mother of one of our friends that much."

She grabbed my hand and held it in place for a while, which felt nice. "I suggest we continue that tomorrow." She sighed. "I'm so glad you got over here. That made my day."

"And mine, " Sally said.

Liz and I agreed that this day had been spectacular. Sextacular, as my sister so eloquently called it.
