I'll get excited more

She was using all of her energy and technique to ride it. She already drenched his dick and crotch with her pussy juice and she became even more violent. He was having a hard time too since the pleasure was too much.

"Hann… sweetie, can I put it in… Hann… I cannot hold it any longer… Hann", she moan and said. She suddenly changed her attacking pattern and rubbed his tip with her pussy hole aggressively.

"Ah! No, mom. You'll get pregnant. Don't do it.", he got startled and tried to reach for her but she suddenly dropped her body against his chest. While huffing she directly kissed him and sucked his tongue. Her pussy hole was working against his tip continuously but she suddenly picked up his dick with her pussy hole by its tip and moved her body backward. His tip directly sunk into her pussy while their kiss was muffled by his word.

"Hann… Don't talk or I'll get excited more… Hann.", she moved her body even faster and sunk his dick even deeper. She instantly felt heavenly pleasure and get excited even more. She kissed him all over his body and started to move her body side to side too. She moved her body so much that she was almost completely drained of energy and she was huffing on his chest but still moving her hip while her vagina milked his dick continuously.

Seeing the tired body of his mother, her effort and intense pleasure from her vagina, in his mind something suddenly broke while his mind buzzed. He remembered the system's recommendation at this time "Don't be bound by the old rules of your world" and this was one of the oldest rules of all. He was always thankful for his system and he do not want to go against it. Did the system already know what was going to happen? Maybe it's his destiny. There is nothing to hold back now. The intensity of pleasure between mother and son was beyond what he could comprehend. Normal sex was nothing compared to incestual sex in terms of sexual pleasure. His eyes suddenly started to blur and he was starting to turn into a beast.

"Ugh… Mom, I can hold it… Huff.", he suddenly flipped her down and started to thrust his dick inside her pussy. He was still alright at this time so he was going slow at first but his speed became faster and faster.

"Hann… Yes… Hann… Fuck me… Hann.", she immediately got stimulated vigorously and her sex drive climbed to the roof. It was an otherworldly pleasure all of a sudden which she never experience and soon she orgasmed.

"Hann… I'm cumming… Hahh", her eyes rolled and her body twitched while her mind turned blank. She did not know what happen after that for a second but when she regained her composure, she was getting pounded even harder and deeper. Her orgasm just subsided started to spike up and something even bigger started to build up inside her. His body became uncontrollable and he kept sucking her nipples while pounding her pussy. He was using a controlled-sized dick first but it automatically became bigger and longer according to what she needed for full satisfaction. When he touched her womb's mouth, he felt extreme pleasure that it tickled his testicle to produce more semen.

"Hann… Yes… Hann… My God… Hann… My womb… I'm cumming….Hann.", she immediately orgasms when he started to poke around her vagina. She moan the loudest and started to squirt her pee drenching the bed. Her body spasmed and her eyes turned white while her mind went blank with pleasure. Her hair was already in a mess and her boobs were jiggling non-stop with pleasure.

She orgasm many times until this time and their body was already drenched with sweat and juices. She blanked many times and every time she woke up, he was pounding her body hard and she felt an earthquake around her body. Her ass, her boobs, and her body was trembling when he was pounding. Despite that, she was not angry at all but excited. Even if there was some pain, the pleasure was exponentially big. Her vagina celebrated the happiness while vibrating itself and sucking his dick even more, her womb stimulated to take anything that is coming inside to welcome it.

"Hann… Sweetie… Hann… cum inside me… Hann… Fill me with your semen… Hann… Hurry.", she was on the verge of collapse so she started to stimulate him with words. Her voice was almost horse after screaming many times but it was sweet to him.

"Huff… But, you'll get pregnant…Hann", he regain a rational mind for a short period of time and said while still pounding hard.

"Hann… Yes… Hann… Make me pregnant… Hann…", she demanded even more while moving her hip with him while her vagina clamped his dick even harder.
