So this is the thing Mimi was talking about

"Alright.", Alex said and started to increase his pace and depth while moving his hips. Gradually their movement became faster and faster. She orgasmed many times and moaned without care. He started to hit her womb with his penis at a rapid pace and she moan at a high pitch. The collision of flesh reverberated around the room and her eyes were rolled and her body spasmed many times. At last, the lust began to build up like never before in their nether region and their movement became much faster. Alex started his last sprint and stabbed his dick continuously in her womb. They reached the limit and Alex penetrated his big dick inside her womb. The grip and suction of her womb were so tight that he started to pour his seed inside her womb, he couldn't move his hips at all, he was stuck.

On other hand, Milly felt so heavenly that she rolled her eyes, droll, and convulse her body. Both of their body started to glow. Soon, the glow started to faint and golden-brown smoke started to come out in their connected region. They observe the process, the smoke started to subside and a golden mixed with brown dragon tattoo was slowly formed slightly above her pussy. It was a life-like tattoo, which glowed for the last time and dimmed down. Milly soon lost consciousness and fainted looking at her tattoo at last. She was still caressing her tattoo with love when she fell asleep.

Alex kissed her sleeping lips and waited for some time still his dick lodged inside her pussy. Alex rolled to the side and closed his eyes for some minute. He got up and carried her to the bathtub and waited for the reaction to start. Soon the black substance started to come out with the black smoke which smelled very disgusting. Alex endured it and observed from the side the entire time. The fat in her body started to melt and her skin tighten at the same time. Her hip and boobs were still the same sizes after losing her fat though. Her change was dramatic and looked like a beautiful black statue at this time. After the reaction subsided, Alex started to scrub her body without any care. He had already cleaned her two times than she slowly opened her eyes. She was sitting on his lap naked and her pussy was still touching her pussy. After becoming red with embarrassment, she finally noticed the black substance and her condition.

"So this is the thing Mimi was talking about.", Milly muttered and started to clean herself.

"Yes. It's the cleaning of your body's impurities.", Alex replied while scrubbing her boobs. She looked at him and lust began to build up in her unknowingly and touched herself beside her pussy and caressed her tattoo.

"Thank you for accepting me.", Milly said and felt the connection between them. They could feel their feeling for each other without telling each other. He can sense, how much she loved him and she can feel the same if they had a wired connection to their feeling. Knowing each other feelings, their bonding became more firm at this time. They couldn't hide any emotion from each other at all. Knowing these feelings, they fell in love even more.

"Why are you thanking me? I know what you are thinking but you are the same as my other wives now. Don't feel inferior to anyone, is that ok?", Alex caressed her body and assured her. She felt more love and she put her head on his chest and closed her eyes for a second with complete satisfaction on her face.

"Okay husband.", Milly became very docile and pampered all of a sudden. After letting her rest and finishing the cleaning process. Alex carried her and dried her with the towel. He took her to the bedroom and put her on the chair.

"Don't you wanna see the change in your appearance?", Alex asked while kissing her lips.

"Oh. Okay.", she replied and started to touch her body. She widened her eyes when she felt the smoothness of her skin. She ran toward the mirror and got shocked. A tear came out of her eyes and hugged him immediately.

"Is that the bad thing?", Alex asked to misunderstand the situation.

"No. I never thought that I will become this beautiful. Thank you, son-in-law.", Milly kissed him all over his face and lips and said.

"Still son-in-law? Alright, whatever. Then that's good. How are you feeling in terms of health?", Alex asked.
