After his little break for science, Leon felt refreshed and eager to finish the RV.
As Leon tinkered away he had a lot on his mind. His wife Miki, her mother, Nila, the twins, that wild blowjob. The prospect of being able to come out of hiding.
"Man, what are we going to do!" He thought out loud to the robots. "Miki needs to get home soon. I can't handle all this overload of libido too much longer. I know the twins are up to something. I know they've been in a sexual relationship with each other, but Nila has done something to them that has changed the dynamic between them, Nila and Myself. Nila has definitely been cooped up too long and has taken our life in quite a sexually corrupt way. I'm not sure it would be a good idea to let them loose on the world unless I get Nila to reverse some of what she has developed before everyone is too corrupted to even think of participating in society. Dammit, I wish Miki was here. I know she had some pretty wild ideas about having the girls join us in bed, but was this what she really had in mind? I don't know if I could take it any further without her. But these new toys Nila made will definitely complicate things. If there is more than one, chances are the twins are involved. Why would Miki approve all this?" The robot closest to him shrugged.
"I figured you wouldn't have any incite, but at least your a good listener. I know I'm quite the horndog but lately it's just been surreal. I don't know if it's a good thing or not but the girls seem to have been okay with it for a while. They just aren't into hiding it anymore. I guess I'll just go with it. I mean, the adaptations I've been given are geared towards something deviant and it seems like I don't have much control or say in any of it, other than being their provider and protector. So, I guess I'll have to be that until things calm down, if that ever happens. At least I make some good looking kids and they live their dad, even if it's in a lot of ways that shouldn't be."
He turned to the robot and asked for a small torque wrench to put the panel to the shield modulator into place. He sealed up the panel, then began testing the upgraded systems. "I gotta say, I don't mind all this hot asian pussy running around the house, though. With my libido the way it is now, I guess it shouldn't be a problem, right?" He continued to say to the robot. "Miki was into some wild stuff back when we first got together. We would fuck everywhere. She would even bring her girlfriends into the mix. I remember how she used to love watching me run through them, hanging on my back, watching me ravage them, talking all sort of dirty things. Hell, I may have even got some of them pregnant too. But we left so quickly and quietly that I wouldn't know. Can't be helped I guess. I'm just glad I got the woman I want and that she is as perverted, maybe more so than I am. Not only that, she is a great wife and mother."
He grabbed the diagnostic computer and hooked it up, making sure everything was in working order before he turned on the RV. "If part of Miki's plan is to turn the family into a harem of super hot Japanese geniuses, I definitely won't complain. I just hope the girls don't decide this is all too fucked up for them and change their minds. I would be devastated if our relationship is ruined and they disown me. Or worse, have me arrested."
The engine turned over smoothly and he took the controls to do a test drive around the compound. Everything worked as it should so he flew back to the overhang and parked, then tried out the camp mode. The pylons dropped, walls extended outward and the roof popped up. He returned it back to the drive setting afterward and stepped out of the RV. "Nice." He told himself and high-fived the robots. "If we ever do get free of all this, I guess I would have a good career in the vehicle conversion business." He took a walk around it one last time. "Well, I guess it only needs a mount for the hover bikes and we're good! Lets go see what the girls want for dinner."
The twins woke up from their little nap and immediately started checking on their newest enhancements. Luna tried out extending her penis while Lina jerked herself hands free with her new tail. Luna looked over and thought her sister was on to something and did what her twin was doing. They both extended their new tongues and wrapped them around the heads of their cocks as they tail stroked them. Both had succumbed to their pleasure, dropping their heads lower to suck their raging girl-boners into their mouths. After a minute Lina said "Hey, wanna try out how long we can deepthroating each other?"
"That sounds like a challenge! We should probably move to the tub. It will save a clean up and give a bit more privacy." Luna answered. They both jumped out of bed and raced to the bathroom and climbed in the bath tub, With Luna laying on her back, her legs pulled back and spread out while Lina squatted over her. Both twins kept their cocks retracted until they had their mouths over each others clits, rubbing their tongues over them, drawing out the dicks like little genies, filling mouths and throats until they were fully extended. They began swallowing hard and rubbing their tongues along the shafts down the the engorged clits. It took them less than a minute to start cumming like crazy into each others mouths, girl goo shooting from their cocks and cunts. Luna's face was a mess as her twin's pussy drizzled her juices directly onto her orgasming visage. Lina pulled off after a few orgasms and posited "I wonder if we could sleep like this? Just deepthroating each other through the night?" Luna could only nod, her neck bulging and closed off from the ten inch rod plugging it, so Lina dropped her head back down onto the hard-on staring at her, waiting to re-enter her throat.
After a good twenty minutes of pleasuring each other they heard their bedroom door open and Nila calling their names. "In here!" Lina hollered as she momentarily released the dick in her face then slurped back down on it. Nila sauntered into the bathroom and sat on the floor across from the tub and leaned against the cabinets a goofy grin plastered on her face. Lina pulled back off the dick and looked over at her older sister, a quizzical look on her face.
"What's with the "cat-ate-the-canary" look, Nila?"
"I sucked dad's dick!" She cooed with her eyes closed.
Luna threw her sister off her face, causing Lina to squawk and slip in their puddle of cunt slime lining the bottom of the tub, and sat up, the twins having dumbfounded looks on their faces. "Shut! Up!" The said in unison. They saw Nila holding her bloated abdomen then looked at each other, mouths agape.
"Holy shit, look at her belly, Lina!" Exclaimed Luna. They both gripped the edge of the tub, Luna wiping the girl-cum off her face, as they waited for Nila to say something.
"Well?" Lina asked. "How did that happen?"
Nila waited dreamily for a moment before she inhaled deeply and said in one breath "I asked him to take a break so I could do an examination and tests of the modifications I gave him and had him come down to the lab and took measurements and couldn't help myself and asked him to suck it and he fucked my face all the way down to my stomach and I deepthroated him and he dumped his cum right in my belly and came so fucking hard the whole time and I loved it!"
"Fuck! I didn't think dad would go for that!" Lina said.
"Oh, you don't even know! Mom has been priming him our whole lives, apparently." Nila returned. "She is worse than he is. Or hornier, I suppose."
"How big is he?" Luna asked.
"Ya, how big?" Lina echoed.
"Seventeen massive inches." Nila sighed as she stared up at nothing, remembering the pilar of flesh she was lovingly violated by.
"Sheeit! Did you do that to him?"
"Yes, with mom's help, of course."
"Well, fuck, you are one lucky bitch."Lina pouted.
