"It's fine, Abi." He seemed to have thought that she only had some minor problems with what he said that could be solved with some words from him. "I know that you're scared that the paint will be stuck to your skin and you'll have a colourful butt for the rest of your life. So, I'll make sure that we use paint that can be easily washed off."

"That's not what I'm worried about!!" She exclaimed, even though what her son said was a thought she also had in the back of her mind.

"Oh, so you want to choose the colour I paint your asshole?" He thought of another problem his daughter might have. "Well, I did want to choose the colour myself. But since you insist so much, I'll let you do it...It's even fine if you choose to make it colourful and turn it into a rainbow, as I'm pretty sure the print of your anus would be beautiful no matter what colour it's in."

"That's not it either, Daddy!!" She didn't know where her son, who was so docile earlier, got so many perverted ideas. "I just want to know why we have to do something as shameful as colouring in m-my bumhole, when we can just go to the park and paint some beautiful scenery there."

"I didn't suggest us to paint, just so that we could make a beautiful painting together." He admitted. "I did it so that we can specifically make a real-life image of your behind, using your orifice as a stamp."

"Why would you want to do something as perverted as that?" Her son's explanation still didn't make sense to her.

"Well, when I was playing with your asshole, I realised that even though you've had it for all your life, you never would've actually seen your asshole yourself." He said, which made sense since it wasn't necessary for anyone to see their own hole. "And even if you tried, you wouldn't be able to, since it's in a place where your eyes can't reach."

"So that's why I thought that if we applied some paint to the inside of your butt and you squatted down on some paper, we would be able to get a perfect print of your asshole?" He said like he was trying to preserve the image of her anus in the most elegant way possible.

"Can't I just see it in a mirror if I turn around and look back?...O-Or couldn't you just show it to me by taking a photo?" She didn't deny her willingness to do what her son said immediately and wanted to know more about his thought process and procedure, since she was kind of interested in what her son was talking about since it involved art, time with her son, and the tingling feeling she got whenever her son laid hands on her, which she all loved.

"I mean, wouldn't it be much more easier that way, Daddy?"

"I mean, it would be easier, and I could probably spread your cheeks towards the mirror in the bedroom and show you how your anus looks right now." He said, which made her asshole twitch like it wasn't ready to be gazed upon. "But a picture or seeing it through the mirror wouldn't be as real as seeing it with your own eyes, and it wouldn't be able to capture the true beauty of your orifice."

"How can you call it beautiful when you've never seen it yourself?" She blushed at the sudden compliment, which she had never heard before.

"How can I not call it beautiful when it belongs to you, Abi?" He said, while deep into her eyes and poking her anus, like he was making sure she knew what he was talking about.

"From your anus, which probably looks like a pink chrysanthemum, to the two tender petals you have down below, which are likely blushing like your cheeks right now, I'm pretty sure that any part of my daughter's body is as beautiful as she is."

"And considering how picturesque your mother's view is down there, to the extent that I sometimes get lost while gazing at her deep hole, I'm pretty damn sure that you're not that far off from her." A sly smile popped up on his face, like he wanted to make two prints with his wife and daughter and frame them side by side to see who's anus looks the best.

"Stop comparing the place I poop out to Mommy's, Daddy! It's embarassing!" She exclaimed in a flustered manner and gripped the tip of her finger that was about to enter her anus.

"And how would that area even reach the paper? It's impossible."

"You don't have to worry about that, as your father has his ways." He said, as if he already planned out how the exotic painting session would go in his head and was ready to carry through with it at any given moment.

"We'll talk about that later, Daddy." She neither denied or accepted what he said. "We first have to focus on the task at hand."

"Oh right. I was just about to stick my finger up your ass." Her son said, which made her realise what they were doing and made her regret reminding her son of it.

And once he was reminded about what he was just doing, he poked her anus once again to see if it would budge. But just like before, it was shut tight and didn't seem like it would let his finger in no matter what.

And even though her son was only poking her hole; like he was using a stick to provoke an animal, she was already feeling it throughout her entire body, as each time his slender finger touched the soft skin of her anus, it would send jolts of electricity throughout her body and would make her jiggle her ass unconsciously.

Her son didn't mind her holding him tighter and tighter every time she could feel something trying to creep into her body, and was trying his very best to get in by wriggling his fingers through the narrow hole.

His middle finger was like a worm who's only way to get back home was through her whole and was trying its very best to enter by thrashing around the outside and trying to stick its head into the crack. And if that didn't work, it would directly try to pierce the hole, which would only make her jolt up and whimper and absolutely do no damage in trying to open her up.

And just when she thought that her defenses were invulnerable and was feeling proud of herself from keeping her son's from entering her, her son suddenly took out one of his hands from her hands. She thought that he had given up and was feeling relieved that he didn't go any further since she was feeling a little too good with what he was doing and she didn't want to get addicted to that sensation.

But out of her expectation, her son didn't simply let her go like she thought he would and brought his hand towards his lips.
