Author here, as usual every character is above or at 18 as per Literotica guidelines.
Also, I know the last story I published wasn't that good because I was pretty sloppy when writing it. This story should be quite a bit better. Also, this story is solely about sex. Alright, if you don't like pee, freeuse, futa, femboy, orgy, incest, or anything I might put in here, don't read it. That's completely fine. Alright, real quick backstory, in this world futas exist, my futa is women with boobs, cocks(some with balls and some without), and pussies(all fully functioning of course). There are also femboys, boys who have a feminine appearance. Also, in this world everyone can fuck anyone in public as long as they both give consent and peeing on each other is incredibly normal, fun fact they can pee at a much higher frequency than normal! Onto the story!
*******************************************
My name is Alex, I'm a 5'6 femboy with a circumcised 8in by 1.5in cock, nice soft and bubbly ass, pretty pink asshole, squishy but defined thighs, and lightly toned abs. Oh, and also completely hairless and silky smooth beneath my eyebrows. I live with two older sisters(both futa), one older brother(femboy), and our mom(futa). In order from youngest to oldest goes me, then Lynsey(first sister), then Kai(older brother), then Zoey(second sister), and finally mom of course because she is obviously older than all of us.
I felt a teasing tongue against my cock as I woke up. I moaned and opened my eyes to see my older sister Lynsey looking at me happily. I had just graduated high school, top of my class and today my family was having a celebration orgy for me!
Lynsey stopped licking once she she heard my moan and jumped up to her full 6'1 stature in excitement, her perfect upper C-cup boobs and 8in by 1.5in cock bouncing. "Mommy told me to come get you up! It's time for the big orgy and mommy prepared your favorite breakfast!" And she rushed out the door and downstairs.
I quickly got up and followed behind her. Once I got to the kitchen, I saw mommy in nothing but an apron, at her full height of 6'4, perky and incredibly soft E-cup breasts, a voluptuous ass, a 9in by 2in cock, and a warm face with soft green eyes and long brown hair.
Mommy looked up at me and said, "Ahhh, baby, it looks like you haven't had your morning pee yet, hold on for a second, let mommy come help her baby." Mommy could tell because my bladder had swelled to a size that it created a noticeable bulge.
Mommy quickly came over and kissed me before shoving my face in her soft boobs and her soft, tantalizing scent that smells like fruity cum. She slipped my cock into her warm, gentle pussy that gently rippled while her cock rested on my stomach. "Come on baby, let loose inside of Mommy."
"Yes, Mommy," I moaned as I started to spray her insides with my delectable pee. Her pussy rippled with gentle pressure but not enough to where I got incredibly hard and was unable to pee.
I soon finished but Mommy kept me inside her, otherwise my delicious pee would flow onto the floor and we couldn't have that. "Lynsey, would you like to come drink Alex's pee?" Mommy said questioningly to Lynsey, who was sitting at the table waiting for Mommy.
"Of course Mommy!" Lynsey jumped up with her fantastic boobs and cock bouncing in the air and ran over. Lynsey knelt by where Mommy had lodged my cock inside her pussy and waited.
Mommy slipped me out and Lynsey quickly held up Mommy's cock and her mouth went straight towards Mommy's warm pussy and clamped over it. Both Mommy and Lynsey moaned as Lynsey sucked my pee out of Mommy.
After all my pee out of Mommy, Lynsey stood up and leaned down to give me a passionate kiss. I moaned as I found she had saved some pee for me, what a considerate sister! I love her!
Eventually Mommy said, "Alright, let's eat! Kai and Zoey are out shopping and won't be back for a while so we will be on our own," Mommy looks at me, "And come over and sit on Mommy's cock for breakfast, it's your special day after all," Mommy said with a smile.
"Ohh, thank you!" I almost squealed with excitement. I quickly separated from Lynsey and went over to where Mommy was sitting. I eagerly straddled her incredibly soft thighs and felt her diamond hard cock in my ass crack.
