Ray held his rod with his right hand and brought its tip in contact to the entrance of her cave.
Since it was already completely wet, he decided to drag his dick up and down, sliding it against her pussy's entrance without entering it.
Then he brought both his hands to her breasts and grabbed them with his palm, kneading them.
"Ahh… Ahhh…"
Isis was drowning in anticipation imagining if she could fit that huge thing inside her.
While she was wondering, Ray gave a mischievous smile, and penetrated her pussy in one full powerful thrust.
"Ihiiiiiiii! Ahhhhh!..... Ohhhh! It's….ahh tooooo bigggg!"
The wildest scream escaped her throat. No one could expect the gentle and innocent looking empress could scream in such a vulgar tone.
Her son had been extremely gentle with her until now, and she expected him to continue doing it the same way.
Never had she imagined that he would thrust that entire thing inside her in one go.
She felt her insides burning in response to the sudden invasion.
She felt her mind going blank but what scared her was that the moment Ray penetrated her roughly… she felt more aroused than ever.
Ray grabbed both her nipples with his fingers and started rubbing them.
"Ahh… its…ahh… too big…"
Isis moaned while she kept saying the same thing.
Slowly pulling back his hips, Ray took his rod out almost entirely but…
*Thwack*
Pounded back in, thrusting with power, entering deep in her in one go again.
"Ahhhhh! Againnn! Ahhhh! It's too … ahhh... Big!"
He pinched her nipples, twisting them and pulling them as he wished, and in the meanwhile…
*Thwack*Thwack*Thwack*
He kept pounding her with his full length, slowly getting faster.
"Ahh!...Ahh! Slower… slower…"
"I told you. Stay true to yourself. You promised me right?"
"Ahh…Ahhh!..."
*Thwack*Thwack*Thwack*
*Thwack*Thwack*Thwack*
Ray kept pounding her faster and faster while he watched as her huge breasts bounced wildly all over the place.
With every thrust, Isis moaned loudly.
The sounds of Ray pounding Isis, and Isis moaning in pleasure filled the room.
After a few seconds of pounding Isis, her moans changed slightly.
"Ahhh… yes….yessss… more…..ahhhh!"
The moment Ray heard that, he stopped pounding, and looked at Isis with a devilish smile on his face.
"Oh? You want more?"
"Ahhh…. ye-I mean… ahh… noooo…"
Isis didn't know why her son had stopped pounding her when she was about to climax once again, and looked at him who was teasing her again with anticipation and fear in his eyes.
'Last time he did this… he asked me to almost beg for it… I'm sure he is planning something again.'
"Mom! Let's make a bet!"
"Haa… haaa… what?...haaa…"
"Let's make a bet. You have already cum thrice, while I haven't cum a single time…"
"…haaa….haaa…"
Isis kept panting while she suddenly knew that her son actually hadn't cum even once, and her ears started getting hot in shame and embarrassment.
"So let's make a bet! If I cum before you, I'll never tease you again and do whatever you want from today on…"
"…"
"But if you cum before me, you have to listen to everything I say from today on!"
"..!"
Isis didn't know what her son would make her do if she agreed and lost the bet, but while her rational mind was telling her to reject it outright, a weird sense of anticipation wanted her to accept.
Seeing his mother hesitate, he started convincing her again.
"Come on, I was still a virgin until a few minutes ago, and you have already cum twice…"
Isis suddenly remembered that her son was a virgin until then. The expert and masterful way he pleasured her had made her forget. And right then another thought struck her.
Ray had given her his virginity!
A sense of happiness and pride spread within her and she was immediately compelled to accept.
"You came twice already, and I am also extremely close to cum… you have a pretty high chance of winning! What are you worried about?"
"…Alright!"
Isis accepted the condition and decided to try her best to control herself.
Ray smiled. Then activated all his aura and sex skills at once and thrust into her again. At the same time he pulled her nipples twisting them.
"Ihiiii! I'm cumminggggg!!!"
Seconds after Isis decided to control herself, one single thrust sent her over the edge.
"Oh my! Looks like I won! You won't go back on your words, would you?"
Before letting her reply, he thrust into her again.
*Thwack*
"Ahhh! Nooo! Its sensitive! I just came! Ahhh!"
But Ray wasn't having any of it. He knew Isis possessed both Self Regeneration and Stamina Restore skills, as such; she could go on for a lot longer.
*Thwack*Thwack*Thwack*
Ray held both of Isis' legs, before lifting them and placing them on his shoulders. Bending her body slightly, he pounded her deeper than ever before.
Isis could feel the tip of his cock touching the entrance of her womb.
"Ahhh… too deep! Too deep! Ahhh!..."
*Thwack*Thwack*Thwack*
After a few seconds of intense pounding and Isis' moaning, he felt the walls of her cave tighten around him, and his cock throbbing wildly.
"Alright, I'm cumming!"
"Not inside… ahhh.. it's not a safe day… ahhh…"
Ray smiled.
"That's all the more reason to do it inside."
*Thwack*
With one deep thrust, he released huge amounts of his white seed inside her, painting her insides white.
At the same time Isis reached climax, and her eyes rolled up as her tongue lolled out to one side.
"Ahhh! It's filling me up! It's filling me up!!"
Pulling out his dick he looked at Isis in satisfaction.
She lay on the bed, her whole body twitching, legs spread apart as his cum kept dripping out of her pussy.
'Yep. That's the Empress, my mother!'
Ray thought he would go for a few more rounds, after all he came just once, but then changed his mind.
'Nah, her mind is already under a confusion spell and she came five times… furthermore… she was pretty tired… I'll let her rest for the night.'
'Besides I cant go too rough the first time, I'll have to slowly get her accustomed to it!'
"Alright mom, I think that's enough! Are you okay? Do you feel alright?"
"Haaa… haaaa… yes… I'm…haaa...alright…"
"Sigh…"
Shaking his head, he lifted her naked body up, pulled the wet bed sheets away from under her, made her sit on her desk, where she weakly sat holding the chair, panting.
Ray then changed the sheets, picked Isis up, cleaned her up using his mana, laid her down on the bed and put a blanket over her naked body.
"Alright then… good night mom!"
"Goodnight!.... and Ray?"
Ray was walking away while he heard his mother call him back. Turning back he saw her looking at him, with only her eyes raised above the blanket.
"I love you!"
She immediately pulled the blanket to cover her head, hiding herself completely.
"I love you too!"
'How cute!'
With a smile on his face Ray left the room but before he closed the door, he said, "Sweet dreams!"
And closed the door.
Under the blanket, Isis closed her eyed and fell asleep with a happy smile still etched onto her face.
She had never felt that happy in her life before.
