Finally

Grayfia leans down and licks Millicas dick with her wet tongue. She massages his balls with one hand and grabs his dick with the other and licks his dick from all sides.

She then takes his dick in her mouth and starts moving up and down. She makes slurp sounds when she takes her son's dick in and out of her mouth.

"Haa!!!~~~" Millicas' breath hardened as he felt his mother's mouth on his dick. He likes her hot mouth.

Grayfia didn't continue to suck his dick for too long. She is not gonna make him cum with her mouth tonight.

She let go of his dick and moved up and sat on his dick. She rubs his dick between her pussy and looks at Millicas.

Millicas looks at Grayfia with expectations. He can't wait to see what will happen next.

Grayfia is feeling very, very happy inside. She can finally be with the person she loves. Even if it's her son she doesn't care. She only knows that she loves him and will be with her from now on. She is also going to take her son's virginity.

She takes off her ring from her ring finger and puts it on the table. Millicas looks at this with a smile but inside he is jumping.

She looked at Millicas and said "Mother loves you the most in the world. Mother will become your Queen, both body and soul. Do you love your mother too?"

Millicas nodded his head and said "yes mom."

Grayfia smiles and lifts herself up. She set his dick on her vagina hole. She looked at Millicas and said "from now on you are a man."

She sits on him slowly as his dick goes inside her vagina hole. She sat on him completely and his dick also reached the back of her pussy and hit the womb.

"Umm!!!~~~~" both of them moan at the same time.

Millicas feel like his dick will melt inside her. It's very hot. Grayfia also felt his hot rod in her pussy. She smiles, feeling her son dick inside.

She looked at Millicas and said "welcome home sweetie."

Grayfia then start to move her hip up and down while she tightened her pussy muscles. Both of them moan. The sound of thrust and moan echo in the room.

Grayfia didn't hold back her voice and continued to move her hip.

"How is it, baby?" Grayfia ask.

"It's very good, mom." Millicas Replied.

"Do you like mommy's pussy?" Grayfia ask again

"I love it, mom. This is the best." Millicas replied with closed eyes.

Grayfia giggles and starts moving faster and give her son more pleasure.

After she moved for five minutes Millicas said "mom, you now lay and let me move." Grayfia smiled hearing him.

She nodded and changed their position in a single swipe. Now Millicas is on top of her. She lay in M with Millicas between her legs.

Millicas lean towards her and start sucking her breast. He bite one light and pinch the other one.

He then start to move his hip and start fucking her pussy. He thrust harder and hit the back of her pussy with his every thrust.

Grayfia moaned again, feeling his hard thrust and hit on her womb.

Millicas then talked with Yuki and said "Yuki buy the vibration skill."

[5000 point deducted, skill "vibration" is added]

[Vibration: can generate vibrations with any part of the body.]

With the description lots of new information about the skill used, filled in his head.

Millicas smirks inside and uses the vibration on his dick. His dick starts to vibrate inside Grayfia's pussy.

"Ahhh!!!~~~~"

"Um!!!!~~~~" "what is this?" Grayfia moans loudly, feeling the sudden intense pleasure. She cum immediately.

Millicas didn't reply to her. He then increase the power of the vibration little more and start fucking her pussy.

He leaned over and licked her nipple and used the vibration on his tongue too. She moan again and grab Millicas head. She wrapped her leg around Millicas and pulled him closer.

"I will die from this much pleasure." Grayfia said as she cum again.

Millicas didn't stop moving his hip. He use different rhythm of vibration inside her. Also lick her nipple with it too.

Grayfia almost rolled up her eyes feeling the intense pleasure. She never Knew sex can be this much pleasurable.

She praised herself for making the best decision of her life. She not only gets someone she love and now her lover is best in something she never actually no can be this much fun.

Grayfia tightens her leg around Millicas and said "sweetie, don't move too much. I am too sensitive already. Please let me relax for a bit."

Millicas stop moving and also decrease the intensity of a vibration to the lowest. He didn't completely stop it.

But he sucked her nipple with continuous vibration.

Grayfia breathed heavily and said " I want it to be memorable for you but instead it became memorable for me."

Millicas lifted his head and looked at Grayfia and said "It's already the best gift. So let's enjoy it together." Grayfia smiled and asked "how did you do that?"

Millicas kissed her and said "it's a secret." Grayfia pouted and said "but I am your mother, wife, Queen and peerage member too. And you don't want to say it to me."

Millicas looked at her pout face and smiled. He kissed her lips and said "you look so cute when you do this." He then complained "Most of the time you look serious."

Grayfia giggles hearing him. Millicas then again increased the intensity of the vibration and said "it's a skill I created myself. And only I can use it. When I will become proficient in it you will see what else I can do with it."

Grayfia moans again, feeling his vibration dick inside her. Millicas again start moving and fuck her pussy with hard thrust.

After a while he looks at grayfia and asks "mom if I cum inside then, can I drink your milk?"

Grayfia pussy tightened hearing his question. She looked at Millicas and said "do you want to drink my milk so much?"

Millicas nodded his head and said "yes"

Grayfia smiled and said "okay then if you cum inside. But I am not sure if you can make me pregnant on the first try."

Millicas smiled hearing her answer. Of course he is not gonna impregnate her this first. He will after he finished all his plan and add others in his harem.

Millicas then gives her a few more hard thrust and cum directly inside her womb entrance.

"Mom, I am cuming inside you."

Grayfia also cum again feeling her son's hot liquid inside her womb.

"I can feel that sweetie."

Millicas lay on Grayfia with his dick inside and took a deep breath. Grayfia also smiled, blessed fully and hugged Millicas.

Millicas use sperm control and D skill on her. Of course he is not gonna let anyone else other than him see her. As a devil they care very little about showing body but in another world he is human so he has human greed and selfishness too.

Grayfia feels very good and also has a little expectation for another baby with her son. She hopes to become a mother again and this time with the love of her life.

Millicas lay on Grayfia with his head on her breast and moved his finger around her other breast nipple and said "mom, can we go to the human world with aunt Rias and live with them there?"

Grayfia combed his hair and said "you want to live in the human world?" Millicas pressed her nipple and said "yes, we here we always stay in the house also there is nothing fun to do. I heard that the human world has many fun things and also many different foods to eat."

Grayfia continued to comb his hair with her finger and said "okay, I will talk with your father. You can also go to the school there."

Millicas lifted his head and looked at Grayfia and said "thank you mom." And kiss her lips. Grayfia is happy as long as her son is happy.

Millicas then again started using vibration on his dick which is still inside her pussy and said "okay then, let's continue to make baby."

"Umm!!!~~~" "yes sweetie, tonight mom is in your care." Grayfia moanthe and Replied.

Millicas smile and start another sex. Both of them decided to enjoy tonight to their fullest.
