Chapter 69 Finally In
She wanted to question him further to get a proper answer, as she really wanted to know how he knew all about this. And if he did have past partners in his life, she wanted to know more about them. She didn't know if it was because of her motherly nature to know about her precious son's relationship or because she was jealous that her son had such an intimate relationship with another woman other than her, but nonetheless, she wanted to know the answer to her question as she simply didn't understand why her son was so good at anything that involved turning her on. But before she could ask anything, she heard her son's head perk up and say, with excitement in his tone, like he had caught a prize-winning fish on his hook,
"It's opening, Abi! It's opening!"
Chill~
That thrilled voice she heard from her son was the last thing she heard before she could feel her anus that had been closed all this while opening up a little after overexerting itself. She wouldn't have normally noticed her anus opening up, as it wasn't common to do so, but because it was exposed to the cold air outside, she could feel a chill in the inside of her butt, where her forbidden hole had decided to reveal itself.
On instinct to the chilly sensation of the outside world, her asshole naturally started to close in on itself, like it had more than enough outside air and wanted to close shop for the day. But just as the fleshy outer ring was tightening up and contracting, it felt something jabbing it from the outside.
"H-How is Daddy? D-Did you fit it all in?" She asked, as she could feel her anus trying to close, only to be blocked by her son's thick finger.
"Fit it all in?" He chuckled. "My finger hasn't even gone in half way through."
"What?! It isn't even half way in!?" She exclaimed in shock, which made her anus tighten up on her son's finger. "T-Then does that mean you still have to push it a bit more in?"
"Why didn't you just shove it all the way in at first, Daddy?...Now, I have to slowly experience the feeling of you slowly creeping up my butt, while I stick my ass out for you." She cried out and complained, as she had thought that it would be a quick process, where his finger would enter her without her even feeling it too much, and didn't expect that she would have to go through and feel each and every single moment of it. "Well, I was going to shove it all at once at first...But as I was pushing my finger in deeper and deeper into you, your asshole started to open up and expand in front of my eyes, and it exposed its inner lining, which was such a pretty colour." He explained how her anus had revealed its inner membrane of fleshy skin around the finger that he pushed in. "And because I was so fascinated by the change in colour, I had to stop and admire it for a second, like a flower in a garden."
"Stop it, Daddy! I told you to stop comparing that place to a flower!" She exclaimed at her son's ridiculous behaviour, even though she was slightly pleased with the compliment. "And what colour difference are you even talking about? Is my butthole not a light shade of purple like you said?"
She couldn't help but think of her underwear, which was also purple in colour and wondered if they were the same colour.
"Well, the outside of your anus is a purplish-blue colour like a morning glory, with streaks of wrinkles on the sides of your rim that are in a darker shade." He described her anus in detail, which allowed her to picture the sight and made her ears turn warm and red. "But the inside of your anus, that is, the inner lining of your hole, is actually a bright blood pink that resembles a Camellia plant, which looks so eye catching that it made me stare at it in a daze for a second."
