"Why the hell is Brent wearing a maid's apron?"
The four siblings started to crack up laughing when their father, Stan asked that question. The parents had just walked in and caught them all relaxing and talking amongst each other, which would have been normal except for the fact that they were all sitting around naked... except of course Brent who was in the apron. The parents sat there staring at them until they all had managed to catch their breaths.
"Nice to see you all thought that was funny," Carol, their mother spoke up. "Something tells me that you all just finished having a little fun."
"They still haven't answered my question yet," Stan said walking into the room.
"Well, me and Beth caught him being naughty," Sasha said with a playful grin. "So we decided that he needed to be punished."
"Were you sniffing the girl's panties again?" Carol said eyes narrowing as her son's face turned red. "I told you they would find out."
"Hahaha!" Sasha started laughing. "And here you were worried about mom finding out."
"I wasn't worried about mom," Brent said looking at Stan. "He's never going to let me live this down..."
"Oh you bet your ass I won't," Stan said.
"So since we got that out of the way I think this is a perfect time for all of us to have a little talk," Carol said walking over and putting her stuff down on the coffee table in the middle of the room. "Why don't you four go put something on?"
"Actually mom...," Sasha said with a smile. "Since this is all coming out and I don't have to worry about it anymore I'm going to come out and say I'm pretty much a nudist, when I'm alone I wear very little to no clothing, so I am going to stay like this if you don't mind."
"I feel the same mom," Marcus said. "We're all comfortable being around each other naked, I don't see it being a problem unless you two do."
"Me too," Beth added. "I like it."
"Um, I guess that's fine," Carol shrugged. "It's how me and your father were mostly before you all were born."
"So another thing we all have in common," Brent said with a smile.
"And I think since we're all naked that you and dad should be too," Sasha beamed.
"Uh, I don't know about that," Carol said.
"Well I think that's a fine idea," Stan said right before he started to undo his tie.
"Here let me help you," Beth said bouncing up to her mother, breasts bouncing with her.
"Thank you but I don't...," Beth wasn't listening as her mom started to speak, instead just going work on Carol's buttons.
"And I'll help dad," Sasha moving up to their father and starting to help him undress.
Beth was amazed at as she started unveiling her mother's body, slowly helping the woman out of the shirt. She saw that her bra for the day had the clasp in the front and wasted no time undoing it, marveling at the sight of Carol's breast, at least a whole cup size bigger than her own. She then moved to her mom's waist, undoing the zipper on her skirt and sliding it over her hips and generous round ass.
"God mom," Beth said taking a step back. "You're so gorgeous."
"Thank you sweetie," Carol said with a smile and a blush.
Leaning down to give Beth a kiss on the forehead, surprise cascading over when Beth lifted her mouth to her mothers. Everyone watched as they kissed intimately, Carol reacting mostly out of shock, but she also couldn't deny how turned on she was. The kiss lingered for a little while until Beth pulled her lips away smiling at her mother. She was about to lead her to the couch when she suddenly excused herself saying she would be back.
Sasha giggled before turning back to their father. She pushed Stan's pants down and smiled at his half hard cock, giving it a soft stroke. She motioned for him to lower his head and whispered something in his ear before giving him a kiss on the cheek. He chuckled softly and nodded before walking over to where his sons were sitting, whispering something to them. It was then that Carol came back in, carrying six towels.
"If we're all going to be nude then one of the first rules I want to establish is that we will be sitting on towels," Carol said handing one towel to each member of the family. "You will not be leaving stains on my furniture. Understand?"
"Yes ma'am," the rest of the family nodded quickly placing towels underneath them.
"Now I realize that this is all exciting, that we've all realized how much we love each other," Carol started again sitting down on the couch between her daughters, Beth on her right, Sasha on her left. "I do want to make sure that everyone is being safe."
Carol waited and saw that everyone nodded agreeing with her.
"Are you girl using protection or on birth control?" Carol asked.
"I've been on birth control for year's mom," Sasha said with a smile. "I have an IUD I got replaced last month."
"Dad brought me to get one of those a few days after me and him started," Beth said with a slight blush.
"I think I know the main thing you want to make sure of as well," Marcus said. "That no one feels like they're being forced into any of this. I think that I speak for us all when I say that we're not."
"Yea," Stan said speaking up. "Everyone knows about me and your mother, how we had started having sex with some of our family members right? While most of it was fun not all of it was. We ran into issues with a lot of people, so we made a few simple rules."
"And now that we're doing the same you think we should adopt those rules?" Brent asked looking up.
"I think we should adopt at least a few," Carol said. "First is as it should be with any relationship is openness and honesty. Example of that is that me and your father are swingers. We have many lovers outside of this family and we don't hide who we've been with. Now for all of you, while I'm sure we'll all be having fun for a very long time I know and encourage you to find other partners if you haven't already."
"Which would bring us to rule two," Stan said. "Absolutely zero jealousy. If you cannot accept one of us being with someone outside this family, then we should not be doing this. We love each other, that will never change, but we shouldn't prevent ourselves from finding someone else, maybe someone you could legally marry and have kids with someday. We having this relationship should never prevent you from finding that."
"Rule three," Carol said. "We will all be going tomorrow and getting blood tests done. We will get them done once a month. I'm not worried about us all, but it's still good practice when involved with multiple partners."
"Four," Stan said. "Protection must be worn when with partners outside this family. You no longer have only your own health to worry about, but that of your brothers and sisters. There are exceptions of course. Going back to if you decide to have a steady partner and want to just be with them is one example."
"Since this started has anyone been with anyone outside the family?" Carol asked.
"I've been with a few while out on the road," Marcus said. "I always use protection unless it's someone I've been actually dating though."
"I have a few friends with benefits," Sasha said. "I also use protection."
"I don't have any right now," Brent said. "Luciana comes back during breaks. We've been using protection because she's not on birth control."
"I haven't been with anyone else yet," Beth said with a blush.
"You don't have to feel pressured to find anyone else either hun," Stan said to his daughter. "If we're good enough for you right now then we're here for you."
"Is that everything you wanted to go over mom?" Brent asked smiling at her.
