"Then, what if I were to grope your ass when your husband is right in front of you, Nina?" Kafka lost the gloomy look in his eyes and asked with a devious smile on her face as his hand got closer to the sinkhole hidden in her butt. "What if I were to absolutely tear it apart by digging my fingers into your meaty behind and twisting your rear like I were trying to take a chunk of your flesh?"
"...Would you shout out and ask your husband to help you out, or at least let out a little plea to make me stop?...Or would you keep silent and get manhandled in front of the man you share a vow with, like the good girl you are?"
Kakfa eagerly asked as he finally reached the end goal.
He immediately realised this when he felt his fingers leave the moist part of her inner butt and suddenly touch some sort of ring shaped entrance, which was even more moist than what he had felt before, almost as if the plump ring was filled with a sweet juice.
"I-I would keep silent, Kafka...Haaa!♡~...I-I wouldn't utter a word to my husband and let you play with my b-butt as much as you want to like what you're doing now." Nina exhaled deeply and whispered some words into Kafka's chest.
She was struggling to speak with someone poking at the entrance of her anus with his finger, like he was checking if it were dead or alive.
"E-Even if he were to catch sight of your hand on my ass, I'd make sure that he doesn't pursue the matter...Nnnn!♡~...a-and then I'd make sure to come back right to you so that you can continue doing whatever you want~" Nina looked up at Kafka with teary eyes and said with a look of resolve that was hidden in her flushed face.
"Good girl, Nina~ What a good girl you are following everything I say no matter how humiliating it may be and going even further to please me~"
Kafka wanted to pat Nina on the head for being so accepting of his words, like he was rewarding a kitty who had done an impressive trick.
However, as his hand was already occupied with the task of spreading her ass and drilling all the way to her delicate anus, he simply rubbed his head against hers, creating the illusion of a pair of primal animals expressing affection for one another.
Rub~ Rub~ Rub~
Nina seemed to be much more elated to see Kafka 'butting heads' with her rather than simply get a pat on the head, which was obvious seeing as to how her asshole never twitched when he patted her head, unlike how it was quivering right now.
Twitch~ Twitch~
Kafka, who literally had two fingers on the outside of her ring, which was made of the most soft flesh, could feel the slightest movements of her anus opening and closing, which made him let out a chuckle at Nina's bizzare behaviour and how her hole underneath felt like a cute little animal trying to swallow his finger whole.
"No, Kafka!~ I do want the reward!~ I'll take anything you give me, Kafka!~"
Nina exclaimed when she felt him pulling his hands out of her round bum and to keep them inside her oven like she wanted, she actually tightened up her butt, which made Kafka's hands get stuck inside of her cheeks.
She then used his hands as a hostage, looked up at Kafka with pleading eyes, and said,
"I'll do what you say, Kafka, so please reward me like you said~"
Just like she mentioned, Nina loosened up the muscles in her firm butt, which was round but not too fatty, and let go of Kafka's trapped hand.
Strech~
She then went even further and loosened up her anus as well, which was actually well guarded until now like an airtight seal, and opened up her asshole to her intense embarrassment.
Widen~
The only time the hole underneath had actually opened up for her was when she used the toilet. But here she was letting the rim of her delicate anus widen in shape so much so that the inside and outside worlds became connected.
And who would believe that all this was for the sake of the boy who she was sitting on top of, who she guessed was going to something really naughty, seeing as to how his fingers crept closer to her hole the further it opened up...
"Kafka, t-this should be enough, right?" Nina said as she expanded all the strength in her body towards blooming her asshole and making it open as wide as possible. "I don't think I can s-spread it anymore, Nina."
"Wait, let me check, Nina."
Unexpectedly, Kafka didn't simply accept her words like she thought he would and directly went to check the source, which was out of her expectation.
He moved his hand closer into her ass, and after his fingers were close to her anus, he used his middle finger, which was the closest one to her hole, to probe it by pushing his finger all the way into her delicate flesh...
