And to make matters even worse for her, he decided to take it a step up, and firmly bit onto her tongue like he was holding it prisoner, and then used his tongue to play with the tip of her's inside the cage of teeth in his mouth. It was like her tongue was a prisoner of war that was strapped down on a table, and his own tongue was the torture specialist who was in charge of extracting information from her.
And the way he was torturing her was by thoroughly harrassing her tongue, which couldn't escape, and abusing it inside his mouth until she even started whimpering to make him stop.
"Hnnnn!~"
"Mmm!~"
He used his tongue as a whip to thrash her tongue around, and slapped it from side to side while making sure that she could feel the roughness from both tongues colliding every time they touched. And then he pushed her tongue against his teeth like he was provoking her and would suck on the tip of her tongue until it got red whenever she tried to push back, as if he were punishing her for retaliating.
And not only was the front of her tongue getting played with, he was also lightly gnawing her tongue that was caught in between his teeth like it was a piece of gum, which made her feel extremely ticklish. She even started to kick the ground with her feet, because she was struggling to fight the urge to laugh and was only able to calm down after he cupped both her cheeks in his palms and pulled her face closer in.
And of course her son's lips weren't idle as well, as they constantly enveloped the area of her tongue that was lying outside and dragged them back towards him, like they were trying to wring out the moisture in her tongue, which felt sensational, as if her tongue was getting a warm and firm massage.
"Haaa~..."
The front, middle, and back portions of her pink tongue were all getting attacked in a vehement manner, which sent tingling sensations throughout her entire body that she thought she could never feel with just having her tongue played. It felt so stimulating to have her tongue treated like a piece of cloth that was being torn up that her eyes started to roll up as she looked at her son's amused expression, and she even started to drool from her bottom lip since she was in a lot of ecstasy and forgot to swallow the saliva that had built up in her mouth.
Luckily, her son noticed this and quickly wiped it with his thumb, or else she would've made an embarrassing scene of drooling right on to her clothes while her son sucked off her tongue. Well, he was wringing out all the wetness her tongue had every time he squeezed her tongue with his lips and was turning her tongue drier by the second, while at the same time swallowing all the saliva that was on her tongue.
He didn't seem to mind that he was drinking his mother's fluids and looked to be happily pouring it down, as she could see his Adam's Apple moving up and down while he had a satisfied expression on his face, like he was chugging down a refreshing pint of cold beer.
Although she was beyond embarrassed and her body was steaming hot, to the point you could cook an egg if you were to break it on her smooth abdomen, she wasn't really thinking about the morality behind her son swallowing her saliva like it was a delicacy and was more worried about how it tasted and hoped that her son wasn't disgusted by what he was taking down. But judging by the look of satisfaction on his face, she felt a sense of relief that he didn't mind the taste of her bodily fluids and even looked like he was enjoying his mother's taste, which made her completely ignore the taboo situation she was in.
"Hnnn~..."
She was so lost in the current scenario that she even stopped trying to pull her tongue back out in fright and was trying to shove more of her pink flesh back into her son's mouth so that she could get a better experience and a better taste of her son's mouth. But her son, on the other hand, was rejecting her advances, as her tongue was already quite deep in, and if it went in any further, their lips would touch.
But his mother didn't seem to care, as she only seemed to want to give herself to him, and tried to push her tongue and continue to barrage his lips with violent movements and was swishing her tongue around like a snake that was caught and wanted to be free. Only this snake didn't want to escape the trap but actually wanted to fall deeper into it so that it could thoroughly experience its son's insides and bathe itself in its son's fluid.
"Hmm!~"
But her son had no intention of giving her way and actually lightly bit her tongue with his teeth, which made her feel a stinging sensation on her tongue that made her aware of how shameless she was acting right now and made her close her eyes since she didn't want to see her son looking down on her behaviour.
She also did this so that she didn't reveal the look of excitement in her eyes, as when she felt that sharp sensation as if someone poured salt water on an open cut when her son bit her, she couldn't help but feel aroused from that feeling, and she actually wanted her son to bite down harder on her tongue so that she could feel that rousing painthat made her bite her lips even after he stopped playing with her tongue.
Her son also seemed to have noticed her abnormal behaviour that was unbefitting of her status as a mother and didn't seem to want to bite her once again, in case she tried to pounce on her lips in a flurry. So he decided to wrap up this strange kissing session that was supposed to be his compensation for his daughter lying, but in the end, it turned out to be her who enjoyed the punishment the most, to the extent of her body shaking and feeling jittery all over.
