My son comes home to a free use household.

Things have changed while my son was off at college. Now can fuck his step mom and step sister too.

During the time my wife, step daughter and I started having fun my son had been away at college. He was a couple weeks late getting home for summer break because his boss told him if he didnt stay for a bit longer then he wouldn't hold his spot for him when he came back to school in the fall. I thought it was a shit excuse and my wife wasn't happy at all about it but we couldn't do anyway about it. I texted and told him and said "hey bud you're gonna be in for a surprise when you get home"
"Dad dani already told me about the Jacuzzi" he said.
I replied "who says I'm talking about that? Just text me when ur leaving college and I'll have it ready when you get home."
"OK dad but now you've got me curious as hell." He replied.
I had everyone install Life360 on their phones years ago so if anyone had an accident or their vehicle broke down then we'd know their location and could come and get them. A few days later he messaged and said he'd be heading home that Friday. I told the girls Charlie would be home that Friday and to make sure their schedules were clear because we were gonna welcome him home in style.
Danielle squealed and said "I can't wait for my hunky step brother to get home. I wonder how college sports treated him. High-school wrestling had him lean and cut but I wonder what shape he's in now."
"Well when he gets home you can greet him in that tiny bikini and see how he reacts. I've gotta tell you thought I've caught him beating off to you both before so I think he'll love the new dynamic"
I told her.
I saw the gleam in my wife's eyes and her perverted smirk at the thought of getting a shot at her step son.
Danielle asked "can I bring Julie over that day? She's had a huge crush on him forever."
"Let him get settled in and used to the new family dynamic first and then her bring her over. I wouldn't mind having some more of her anyway" I replied with a grin and then said "if you're lucking we could double penetrate you."
"Damn that made me wet at the thought of him in my pussy while you're fucking my ass and I'm eating momma's pussy" she said.
I reached down under her skirt and found her pantyless and true to what she said she was definitely wet so I slid 2 fingers into her pussy and started finger fucking her.
My wife pulled off my pants and started sucking my dick while I was making danielle cum with my fingers. When I was rock hard I pulled her daughter over onto my lap and she sank her ass down on my cock facing away from me. I stood up with her ass impaled on my cock and held her up by her thighs so her mom could get to her daughter's dripping pussy. I held her up and fucked her ass while her mom worked to see just how many fingers she could get into her and sucked on her clit.
Danielle hollered "OH FUCK MOMMA I'VE NEVET FELT SO FULL! How many fingers is that?"
Her mom let go of her clit and said "baby ive got 3 inside you and im about to try for a 4th. I can feel your daddy's cock slide in and out of your ass through the wall of your pussy."
"Do it momma stretch my pussy some more. I wanna feel your fingers tickle my cervix" she panted.
I felt her ass get a bit tighter and could feel my wife's fingers rub the underside of my cock through the wall of flesh between her pussy and ass.
I said "damn baby how many is that? I can feel your fingers on my cock and fuck its gonna make me cum."
My wife said "ive got 4 im her and I can feel the back on her pussy. Cum in her ass so I can feel you pulse from her pussy."
With that I roared out and came hard in her ass. I pulled out of her ass and my wife sucked my cock into her mouth as soon as it came to bare to clean me off. She pulled her fingers out of my daughter with a wet shlucking sound and right as she was angling my cock to insert into Danielle's pussy my knees gave out and I dropped onto the couch. When I dropped it caused my cock to slam into her pussy balls deep all in one go and jam the head of my cock right up into her cervix.
"JESUS CHRIST DAD ARE YOU TRYING TO GET YOU DICK UP INTO MY WOMB? I know I said I like my cervix hit but damn" She said with a start and bugged out eyes.
"I'm sorry baby girl my knees gave out. It's a good thing I landed on the the couch though since its got some give to it. If we'd have gone all the way to the floor then I might have punch through your cervix all together" I replied
"Yeah that would definitely be a new experience but would certainly be painful" she said.
Her mom leaned forward and spread her daughter's knees open so she could get to her pussy.
She said "I just love how your pussy looks spread open by your daddy's thick cock. Hold that position you two and ill be right back."
When she came back she was holding a video camera, my digital camera and some baby oil. She squirted the baby oil all over Danielle's pussy to give it a good shine and set up the video camera aimed at our position and turned it on.
She set off to the side and started directing us so she could get some hot shots. "Chris reach down and spread her pussy lips open as far as you can so I can see just how far she's stretched open. That's it baby and pull her clit hood back." She clicked a few pics and said "now baby started riding ur daddy nice and slow so I can get some pics with him pulled most of the way out."
She backed off and danielle started to ride me slowly and took over holding her lips open and and started rubbing her clit. I could feel the cum i pumped into her ass pooling on my lap and mixing with her wetness into a gooey mess. My wife loved how it looked. She had me lean back and pull my step daughter onto my chest and let my cock slipped out of her while still holding her lips open wide to get a few shots of her gaped open pussy.
I couldnt take it any more and drove my cock up into her and leaned her forward before instructing my wife "baby take off your clothes and get up here so she can lick your pussy. We can take still from the video."
She hurriedly stripped, stood in front of danielle and pulled Danielle's face pforward into her dripping pussy while I fucked her. We went like this for a while until I pumped her pussy full of cum.
I pushed my wife away and leaned back again so my cock could fall out of her pussy and the camera could get a good look at her well fuck ass and pussy leaking my cum. I pushed her off to the side abd pulled my wife back over to fuck her in the same position. She end up full of my cum and showing it off for the camera as well.
After our fun we cleaned up the mess and went to editing the video and pics to play when Charlie gets home.
Over the next few days while we waited danielle was naked in the house and constantly dripping wet in anticipation of her step brother fucking her. The house became free use and we fucked all over the place.
Friday finally came and Charlie sent me a text saying "hey dad I'm heading to gas up the truck and then ill be on my way home. I can't wait to see everyone."
"OK son we're excited to see you. The girls most of all" I replied back to him.
We spent our time making sure the house was cleaned up and prepping the Jacuzzi. I noticed his position on Life360 was getting close and said "OK girls go put on your skimpiest and sexiest bikinis and lets get out in the Jacuzzi." Danielle put on her tiny bikini and my wife pulled a micro bikini out that was so skimpy it the top only had triangles big enough to cover her nipples and a string of beads on the bottom that covered her pussy slit but left everything else open to view. I was rock hard when I saw it and told danielle "damn baby girl ur mom is sex given form. We need to find one of those for you."
"Why Chris? After today I'll be naked whenever I'm at home anyway" she said with a sexy grin and pulls her tiny bikini bottoms right up between her pussy lips and rubbed it against her clit. When we got outside I pulled danielle onto my lap and replaced her bottoms with my fingers. When my son got home and rung the doorbell, I sent my wife out to great him with a sexy smile.
She opened the doors and saw his arms were full with bags and his eyes nearly popped out of his head. He looked her up and down and she said "well are you gonna stand there gawking all day or are you gonna give me a hug?"
He dropped everything in a heap and scooped her up in a tight hug. She stepped back and started feeling his muscles and said "damn boy you were ripped when you left but you're built like a brick shit house now. Go put your bags up in your room, get your trunks on and join us out in the Jacuzzi."
He didnt take long to get out there and damn did he ever pack on the muscle. Danielle jumped out and grabbed him in a tight hug. "Holy shit my hunky bro went to college fit and came back with even more muscles."
She started feeling him up before grabbing his cock through his trunks making him jump. She dropped down pulling them with her and immediately sucked his half hard cock into her mouth and started in with a mind blowing blow job.
My wife spoke up and said "baby girl you better leave some of that stud for me." she stool up and I pulled her micro bikini off and my son's eyes bulged ever more and seeing his hot step mother naked. I shove her over the edge and slipped my cock into her pussy from behind. She motioned him to come closer after telling danielle "OK baby let me have some. You can't hog all of him."
When he was close enough she grabbed his cock and said "like father like son. Us girls are very lucky. Two big thick cocks in the house to fuck us." She looked up at him and asked "do you like your surprise?"
"Hell yeah I do but when did this happen? And why is dad OK with this?" He asked.
I told him "its been a thing for a about a month or so now and we've become a free use household. Only select few outside the family know about this so keep it to yourself. You can fuck any of the girls whenever you feel like. You dont even need to ask just come up and start fucking them."
I directed danielle up on the deck so I could fuck her and left my wife for charlie. I had danielle give us a sexy little strip show that left Charlie with his jaw dropped as she ended it by spreading her pussy lips open so he could see just how wet she was.
She gave him a sexy grin and said "after your dad fucks me I want you to come over here and fuck me. You have a thick cock just like him and it stretches me oh so well."
Charlie just rapidly nodded his head unable to speak. I set her down on her back and pushed her knees up by her ears ao I could get in deep just like she likes. She must have been really excited for her step brother to join in on the family fun because she was so drenched I had no trouble sinking all the way in til I nudged up against her cervix. I started fucking her hard and she didnt take long to orgasm and was so horny she squirted juice all over both of us. I kept going through 3 more gushing orgasms before cumming in her pussy and switching to her ass. I sunk in balls deep before fucking her hard and deep.
She was moaning like crazy and saying "oh yeah Chris keep fucking me until you've cum in both my holes. I wanna show bro how I look with cum pouring out of both holes before I have momma clean me out for him to fuck me."
I looked over and Charlie was fucking my wife on the side of the Jacuzzi while sucking on her tits and playing with her clit. I asked my wife "how's our boy doing honey?"
"Holy shit if I knew he could fuck like this then I'd of fucked him long ago. He eats pussy like he's starving too. Like father like son he's long and thick" She said.
"How's she feel son? I've seen you checking her out many times." I asked my son.
"Damn dad even though she's ur age her pussy is still tight and these tits are incredible. I'm feeling like I'm gonna cum already" Charlie replied.
My wife spoke up and said "I've had my tubes tied so cum inside me son. I wanna feel you fill me with your cum."
He sped up a bit and then buried himself inside her and pumped a huge load into her. Next I saw was my son flop over backwards and my wife climb out to start sucking him hard again and clean him off for danielle. Seeing him cum in my wife pushed me over the edge as well and I filled my daughter's ass with cum. I slipped back into the pool after that to wait for my wife to finish. I told her "hey baby danielle is ready for you to eat my cum out of her."
My son and wife both stood up at that. My wife to move to clean up her daughter and my son to see Danielle's condition.
Danielle saw him staring and spread her pussy lips for him before saying "bro ive always though you were hot and have fantasized about you fucking me and leaving me looking just like this."
"So have I dani. Ive always thought you were a babe and all my friends and teammates agree with me. I've snuck peaks at you whenever I could but I never imagined just how hot you really were or how much of a freak in bed you are. I can't wait to test out every fantasy I've had about you and your mom before I go back to college in the fall" my son replied.
"Well then come over here and fuck my tight pussy nice and deep big brother. Momma's done cleaning me up and I want you to fill all my holes with your cum. Don't worry about knocking me up, ive already taken care of that" Danielle said.
My wife entered the Jacuzzi and we repositioned ourselves to be able to watch our offspring fuck. My wife sat herself down on my lap and inserted my cock into her pussy. I could feel my son's cum still in her pussy prelubing it for my entry into her depths.
While we fucked we watched Charlie fuck danielle like a wild man and she moaned out instructions now and then. It wasn't long until she was cumming and my son right along with her. She rolled them over and made out with him while he was still buried in her pussy. She lifted off his cock and positioned her ass over his cock before slipping it inside. He grabbed her hips and spun her facing away and called my wife over to lick his cum out of Danielle's pussy while he fucked her ass. I sideled up behind my wife and put my cock back inside her pussy. We all fucked as a group until both girls were fucked full of cum.
We all rested in the Jacuzzi while playing here and there. For the rest of the summer there wasn't a single day that someone wasn't fucking someone else randomly in the house. I came down one morning for break fast to find my family naked and Charlie plowing his step sister on the table. On another time me and Charlie double teamed danielle. She loved having both her pussy and ass full of cocks and feeling us cum in her.
At the end of the summer break Charlie went back to school with promises to come back more often to fuck his sister and mother. We started posting anonymous pics and videos online of us all fucking each other so we can look back on our favorite moments together later. Danielle also said she'd bring julie over for one of those visits too.
