This is a CUCKOLD story, if you do not enjoy the theme, please don't waste your time.
Thanks for all the feedback, I know this first person narrative isn't exactly correct, but it has a purpose in my head, it's intentional and will remain this way.
This one I submitted without an editor to speed up the delivery, let me know what you guys think, if it isn't that bad or if I should use an editor for part 5.

I woke up from my nap and Rose was gone, there was some noises and a big splash in the water, I checked outside the window It was getting dark, when I got close to the window I saw Rose sitting in the edge of our pool wearing a blue dress, her hair was wet and she and Ben were laughing at Mark which was swimming close to the other edge of the pool.
I heard music and noticed a few cans of empty beer piled in the corner. I was anxious to see If they were up to something but everything looked normal.
But then Mark emerged pointing at them saying:
"Who's next!?" They just laughed.
The water close to him calmed and I rubbed my eyes to see It clearly. I saw a big skin colored thing floating attached to Mark's hips and finally it hit me! Mark was swimming naked and calling them to take their clothes off too. I felt a rush of blood going to my dick and my stomach revolved thinking that either I remained hidden upstairs just looking or, to participate I would have to be naked with all of them and I was the smaller one.
Rose had shown her naked body and done things to both of them but I still neither saw them or was seen naked. I was hoping that they didn't take their clothes off and things remained that way. But then, Ben stood up where he was sitting with Rose, danced a little and downed his shorts showing his semi hard cock. He jumped splashing water on Rose, she acted angry but they all laughed.
Now Ben and Mark were naked and calling for Rose, she denied for a while but finally stood up and danced teasingly untying the knots on her shoulder pretending to pull her dress off, but then she suddenly lifted her arms in the air and jumped dressed in the pool.
She did It in a way her dress remained on the surface of the pool when she dived, she emerged naked but hidden by the water mocking at their disappointed faces. I was excited but nervous. They were all naked in our pool and Rose didn't have limitations anymore, she could do whatever she wanted with them, I imagined a lot of possibilities and finally decided to join them. I would have to deal with my shyness and overcome showing my smaller cock but I needed to be there for the naughty stuff! I freshen up quickly and went to join them.
"Look who's back alive!" Rose shouted and lifted her body on the edge to give me a kiss showing me her perky tits shining from the water. She lived with me for months but never swimmed naked.
"Baby, would you please get us some beers? The guys want me to get It for them but I'm afraid they might see me naked." She pretended to be innocent but I could notice she was tipsy.
I grabbed some beers from the cooler and opened one for myself and laid down on the resting chair.
"Come on, man, join our naked kingdom!" Mark yelled, jumping in the pool again swinging his junk in the air. I laughed but still was nervous about it.
"I'm starving, let me first order some food for us." I gained some time.
"Pizza!" Rose yelled higher than she expected and laughed at herself.
"Pizza It is then! It's on me If I got to pick!" Everyone cheered, agreeing and Mark left the pool and asked for my phone to choose the food to our address. He dried his hands on a towel and I handed him my phone and he stood there close to me with his big junk hanging close to my face. He was bigger and thicker than me, even soft. He took his time standing there making me uncomfortable and after what seemed an eternity finally handed me back my phone and looked for his wallet and handed me a hundred.
He dived back into the pool and Rose and Ben were holding on the edge talking and suddenly Rose yelled in pain, Mark emerged laughing.
"Owch! Not funny! That hurts!" Rose complained and I knew Mark had swum to her and bitten her ass and the three guys laughed and my dick hardened a little.
"I just couldn't help myself with that ass!" Mark said and bitten the air looking at Rose and we laughed and again I felt proud of her beauty.
The night was promising and I decided to drink faster for when my time of being naked arrived.
We drank and talked about many things. Mark asked us about our jobs and big projects and also talked about his company and how great he was doing. I told them about a project I just finished and how my boss would travel to present on Monday and they were proud of me.
Ben was starting to grow in his company too and we cheered for him and Rose told us about how everyone in her office thought she was such a prudish girl.
"Prudish indeed, if she doesn't like something she would just pick her clothes and leave!" Mark provoked her and we all laughed.
We chatted and laughed a lot, everyone was so comfortable and the nudity felt natural, there was some teasing but everything seemed natural and fun.
The pizza guy arrived and I went to get it under protests from the guys who chose Rose to pick It naked. When I returned I heard her saying "the neighbors can't see anything" making a funny voice quoting me. That made it clear she was already drunk but still remembered the Rules.
I dropped the pizzas on the table and took a slice to give to Rose in the pool. When I turned she was standing behind me smiling like a naked goddess with the dripping water shining in the low light. We enjoyed the view for a while and she sat hiding most of herself behind the table and we all ate.
After the pizza, I said, "Fuck It!" I downed my shorts and ran naked and jumped in the pool yelling "Naked Kingdom!".
Rose clapped, Mark and Ben burst into laughter. I swam for a while feeling free. I even floated for some time leaving my dick out on the surface.
"Look Ben, that girl from the Beach responded to my text! They want to meet us at a bar!" Mark showed Ben the text on his phone.
"And you're thinking about going?" Rose was disappointed.
"Well, I have the duty of finding out which one is naughtier!" Mark held his hand on his chest acting like an honorable hero.
"I don't know If I want to go." Ben didn't seem interested.
"Well, I think you should stay here in the naked kingdom." I wasn't sure If Rose was just sad to end the playtime or jealous.
"Come on, man, we can hit the jackpot there, three of them for only two of us!" Mark tried to convince him.
"So I'm just not a good enough prize then!" Rose exaggerated her sad puppy face.
"You are the best prize!" Ben tried to cheer her up.
"But I don't think you can't handle pleasing ALL of us! I am kind of doing this for you, to lighten your burden." Mark used his twisted logic.
