Walking down the hallway from her room a little while after everyone went to bed, Eris silently crept to Osiris's door and knocked as softly as she could muster.
When she saw the door open, her eyes lit up in joy when she saw Osiris smiling face greet her before he spoke.
"You couldn't sleep again huh? I guess it can't be helped, come in".
All Eris could do was smile as she walked into the room, but her smile stiffened on her face when she walked past Osiris and was met by the sight of Aria already sitting on the edge of the bed in her pajamas.
Osiris closed the door before Eris turned to him and spoke with unknown emotions flickering in her eyes.
"Why is Aria here in your bed".
And Osiris calmly walked into the middle of the room between Eris and Aria and spoke.
"Me and Aria have decided to enter a loving relationship with each other"
He spoke while looking over into Aria's silver eyes with a loving look, but behind that look was a budding all consuming sense of possessiveness which Aria could feel when she looked back with the same loving look and a smile.
Osiris then turned to look into Eris's matching silver pupils with a serious look before explaining.
"And i have asked if it would be alright if she shared me with you, to which she said only if you agree".
"So I'm asking you now, Eris, I believe I have fallen in love with you".
"Would you do me the honor of being my wife".
And when Eris heard him, a sense of joy coursed throughout her entire being when he said he loved her but she didn't let it show as she asked for her own clarification.
"So basically you want to marry both me and my sister, and probably other woman in the future if you're already greedy enough for two".
She asked while staring back into his eyes, to which he promptly nodded, Eris then turned to Aria.
"And you're okay with this?".
To which Aria nodded and said with a smile.
"Yes, I've fallen in love with Osiris and am ok with sharing him as long as you agree and he does not show favoritism, including future women".
Eris then stood there with her head down for a while thinking it over, before eventually she looked up at Osiris and smiled, followed by a nod.
"I accept, as long as you love both of us the same and never neglect us, I will love you with all of my heart".
Both Osiris and Aria beamed with smiles at hearing her response, Osiris then walked over to Eris and stood in front of her.
With their whole 1 foot height difference ,with Osiris at a whopping 7'0ft and Eris's 6'0ft, Osiris had to look down at Eris while she looked up.
When Osiris got close enough for Eris to feel his hot breath and smell his manly scent, she blushed as she looked up at him and Osiris spoke.
"Truth be told, you never truly had an option to run away once we had shared the bed that night, after all I wouldn't let just anyone share my bed".
"Now how about we seal this deal with something I think we have both been wanting to do".
Eris heavily blushed and closed her eyes when she saw him leaning down towards her, her heart speeding up like a marathon racers.
When their lips met, it was that same explosion of pleasure that happened with Aria, an unexplainable phenomena.
Only this time instead of tasting like a ripe citrusy orange that Arias lips tasted like, Eris's lips tasted like sweet cherry's freshly picked from a tree.
Osiri's arms snaked around Eris thin waist, bringing er into a deep and warm embrace as her own arms wrapped around his neck, pulling him deeper into her.
Eris, just as inexperienced as Aria was when they had their first kiss together, was just as quick when learning as she quickly got the hang of it.
This went on for a couple minutes until they both heard Aria clearing her throat and caught their attention.
As they broke their kiss and turned to look at her, Aria said.
"I think it's been long enough, I'm really happy that everything worked out and all that but I'm truly tired and ready to sleep".
Eris blushed at realizing her sister was watching her the entire time, but wasn't too embarrassed as she and Osiris both laid down in the bed.
Osiris in the middle with Aria on his right towards the door and Eris on his left next to where the bed met the wall.
'I need to get a bigger bed in the future'
Osiris thought while wrapping both of his arms around the girl's waists and they got comfortable, laying their heads on the left and right sides of his chest respectively.
'But it's not all that bad i guess'
He thought with a smile on his face as he closed his eyes and drifted off to dreamland.
Early next morning, Eris and Aria both seemed to wake up at the same time inexplicably, smiling at each other as they had both found the man they were going to spend the rest of their lives with.
They both then looked up at his sleeping face and Eris commented.
"I'm actually kinda happy we both found a loving man who could take care of both of us, since i couldn't picture my life being seperated from my sister"
"I'm happy Osiris found us too, it feels as though it was meant to be".
Aria responded before she looked down at his body, just as fascinated and aroused as Eris was on the first morning, but as she looked further down her face suddenly froze, her eyes widening as she stared at something.
Seeing her sister's reaction, Eris got confused at what would make her react like that, when she looked down as well and immediately blushed, seeing Osiri's gigantic 10 inch member in all its glory, poking straight up as if challenging the heavens to its might.
"He is a strong, healthy man after all".
Eris spoke shyly as Aria nodded her head absentmindedly, never breaking eye contact with the huge beast that seemed to have slipped out of Osiris pants and was set free.
And unlike Eris's shy nature, Aria's curiosity got the better of her as she reached out and actually grabbed it, slowly stroking it as she felt the heat radiating off of it and the bumpy veins that ran along its length.
Seeing her sister's actions, Eris quickly voiced out.
"What are you doing, how could you do something so erotic to Osiris while he's asleep, what if he wakes up".
And hearing Eris panicked whisper, Aria smirked while saying.
"He is our husband now, and it is our duty as his wives to take care of stuff like this, and we were going to do it eventually so I see no problem with it".
"Why don't you join me, I know you're curious at how it feels".
And Eris, though hesitant, was persuaded by the devil in her ear to ignore her self conscience and touch Osiri's member at the top, while Aria got the bottom half.
Together they explored Osiris manhood, stroking it in different ways as they noticed different reactions from it as they fondled.
They were so caught up into the action that they both failed to notice Osiris awake, before saying.
"Well i wasn't expecting to wake up to the scene of my wives giving me a handjob".
Aria and Eris both jumped slightly when they heard his voice, Eris even going as far as accidentally tightening the hand around Osiris penis considerably, which led him to wince a bit and said amusedly.
"Easy there, if i wasn't as strong as i was, you might have just crushed my penis".
Realizing her mistake, Eris loosened her grip as she apologized embarrassedly.
"Sorry you startled me, and i hope you don't mind us touching you while you were asleep"
"I don't mind at all, i love my wives being proactive, and it feels very good to say the least"
He spoke with a loving tone which sent Eris and Aria crazy, making him take turns making out with them while they both worked together to make Osiris reach his limit.
And 30 minutes later, Osiris suddenly spoke out.
"I'm about to come".
To which Aria surprisingly leaned down and wrapped her lips around Osiri's penis and started licking the tip and sucking.
Making Osiris blow his load even harder as he came in her mouth, and Aria sucked and swallowed every bit of it up, not letting a drop go to waste.
Once he finished cumming, Aria broke her mouth off of Osiri's penis before cleaning him off and looked into his eyes while saying.
"How's that for being proactive".
Eris stared at her sister dumbfounded, while Osiris looked at Aria with love hearts in his eyes, saying.
"You are never escaping me"
Before Aria laughed and replied.
"I never planned on it".
they all got up and headed their own ways, Aria and Eris went to their own rooms to get changed for the day, and Osiris went to the bathroom to take a shower.
Later, they all went to the dining table and spoke about what they planned for the day.
