The knock on the door came as he was struggling with his ass, trying in vain to find a speedy method of ridding it of the ungodly amount of cum his mother had deposited there.
"What? I'm kinda busy in here..."
"I know," came his dad's voice. "I think I got something here that might help."
He waddled over to the bathroom door, trailing a thin drizzle of cum behind him. He opened the door, peeking his head out. "Fucking stuff won't drain, it'll take me hours to get rid of it..."
His father laughed. "Yeah, you gotta learn the technique. But I think you'll find this helpful..."
Terry looked at the object his dad was holding out to him. He really WAS way down the rabbit hole... "is... is that a dildo?!"
It was short - about 4" - but thicker than what he expected a dildo to be. And - it had a large hole running through its length... what the FUCK?
His dad nodded. "Well, sorta. It's actually a plastic cast of your mom's cock, have been getting them custom-made for years. Made this one especially for you... well, if you want it."
Terry guffawed. "Jesus! You guys are serious about this thing!"
John shrugged, looking slightly embarrassed. "There ARE a lot of logistics you have to take into consideration... though, I dare say it's a bit more complicated for the ladies..."
'The ladies'... he was going to fuck - well, be fucked BY - his mom and his sister, apparently on a pretty regular basis (his mom, anyway). He'd better learn how to deal with all the 'Logistics'... He reached out and took the fat appendage. Damn, his hand couldn't even reach half its circumference...! He smiled, thinking about the original, his mom's mammoth cock, throbbing inside his body...
His dad smiled, recognizing his smile. "It was good, wasn't it?"
Terry looked up at him. "Dad, it was the greatest feeling in the world...!" He hesitated, then said, a little embarrassed: "you know, ever since I saw mom fucking you... I always remember the expression on your face. It was like you were, like you were in heaven or something..."
His dad smiled, putting his hand on his. "I was. 25 years, and every day was like this..."
They looked at each other, smiling like idiots - very HAPPY idiots. His dad sighed. "Damn, kid, I envy you... A whole new world to discover." He cocked his head. "Well, I hear your grandma's car. You'd better finish up." He put his hand on his son's. "Hey - your sister is dying to fuck you, don't let her in or we'll never get to dinner. There'll be time enough for that afterwards."
Terry's eyes opened wide with excitement. His sister was here! After years of teasing, she would finally have her way with him! He was all for it - he had spent most of his teens jacking off to pictures of his mom and sis, about fucking time he had a taste of the real thing! - but his anus was still sore from the pounding his mom gave it, and he needed some recuperation time... "I'll try, dad, but you know how she is..."
His father sighed. "Well, she IS a strong-willed girl..."
"...AND super-strong..."
"AND super-strong, right. But you've got to stand your ground." They both cocked their heads as they heard the main door open, downstairs, and the excited voice of a 21 years-old futa. "Well, she'll be here in a minute. Just remember you DO hold some power in this..."
"Power?! What sort of power?"
His dad shrugged. "Well, you'll learn. Remember: this is all about give-and-take..." there was the sound of someone running up the steps - 180 pounds of toned futa muscle, heading their way. "OK, lock it and don't open up! And that thing - it's very intuitive to use..."
Terry locked the door, and stood, listening, his hand at his back, playing with the plastic mom-cock. Did he dare push it in? It somehow seemed too... well, weird.
He heard a squeal as his sister reached the top - less a 21 year-old girl, more like an elephant in heat, he thought, amused (and a little excited). He heard two dull thuds - his grandmas' suitcases, he guessed, hitting the floor, and then a deeper thud - his sister picking up their dad and slamming him against the corridor wall. There was a short silence - some smooching, as was to be expected - and then, after a minute, the sound of his sister's voice.
"Woof!! I missed that. Hope mom's been keeping you limber, dad..."
His dad, sounding out of breath: "well, she's doing her best..."
"I bet she does, I BET she does!"
Terry smiled, recognizing the Monty Python reference. He felt his pulse quicken. Up until today, he was kept out of all those activities, only catching glimpses or sounds - he was now going to be in on this! He felt his dick stiffening a bit. Man, he wanted so much to see his sister!
"OK - where's the half-pint? Got some business with him before dinner..."
"Now, Sara - we don't have time for this, dinner is at 8, don't..."
"Relax, dad, just want to see the little fuc... err, my little brother, say hi. Don't worry about it. And you better go down and say hi to grandma. Grandpa has been getting on her nerves the whole trip, she's NOT in a good mood..."
Yeah, that would do the trick. "Seriously, Sara - he has gallons he needs to get rid off till dinner, don't go putting any more in there!" His voice faded as he went down the stairs. He heard his sister's steps coming near, then - a knock on the door.
