Jackson and Alexa

John figured that maybe if he asked his kids how they felt, then maybe he could know how he should feel. He went back across the hall, still naked, and stood in the open doorway of Alexa's room. They had clearly just finished as Jackson's dick was still hard and Alexa's tits were covered in his cum.

"A little late Dad, but I'm always up for another round. I'm sure Jackson doesn't mind watching." Alexa says, winking at her brother.

"Thanks for the offer but I'd rather talk if that's okay. With both of you." You say.

"We aren't in trouble are we? It was her idea, she **** me." Jackson says, panicked.

"No, no. Nothing like that. I am actually curious why you guys did what you did. How did it start?" You ask.

"Obviously today was the first time. I had never looked at Jackson in that kinda light before. But after those changes you made to the app, I thought why not? I'm always horny and I'm stuck in this house with this ankle monitor. Jackson is 18 so I can rightfully assume he is horny 24/7. It just fit." Alexa answers truthfully.

"Wait, you guys know about the changes I make in the app?" You ask, puzzled.

"Kinda. It's hard to explain. I know about the app and the rules in them, and I know when they come into effect, but I don't really think about a before and an after. If that makes sense." Alexa says.

"So you know about the changes as I make them, but you don't really consider them new as you don't compare the rules of now against the rules of the past." you ask.

"I guess that's a good way of putting it. If you make a change shrinking Jackson's dick to 2 inches, I won't be comparing it to his current 7 inch dick. I will know that it was changed, but I won't really know what it was changed from."

"Hey, leave my dick alone. You seemed to be enjoying it earlier." Jackson says teasing.

"Okay. And the brother sister stuff? It doesn't bother you?" You ask.

"Not really. The app made a change where we can be horny in the house. If it's normal to be horny, why can't we be horny together?" Alexa adds.

"I guess that makes sense. I guess I should stock the house up with a lot more condoms. We probably don't want a bunch of deformed babies running around here." You say.
