Gabriel had come to the underworld to check on Sullivan. It had been quite a while since she had seen him.
She could feel that the core of the universe became stable, which meant Sullivan had done a great job.
Gabriel came to Gremory Castle and went straight to Sullivan's room and that's when she heard a strange noise coming out from his room.
And when she heard that strange noise, she knew right away that Sullivan was doing something to his woman.
"Hum, my nephew is really good at seducing women. Just like his father."
Gabriel came inside the room and witness Sullivan was fucking Yasaka.
After Sullivan finished his duel with Riser, Yasaka asked him to help her, and he, who had decided to become her lover, immediately agreed to help her.
Who could refuse her when she asked them seductively?
He thrusted his dick deep inside her pussy from behind and released his thick semen inside of her again and again.
Yasaka dig her claws into the bed as she received Sullivan's semen inside her womb.
She gained a lot of power from having sex with Sullivan.
Her belly swelled after being injected with semen into her vagina.
She screamed with lustful emotion.
"Make me pregnant now. Inject your sperm into my pussy again, Sullivan!"
Hearing that, Sullivan did as she wanted. He fucked her harder before cumming inside her again as she wanted.
Yasaka was feeling very full after receiving Sullivan's semen again.
She passed out after that, her stomach swelled like a pregnant woman.
She was addicted to the sex that Sullivan gave her.
"Are you satisfied, Sullivan?"
Gabriel spoke as she approached Sullivan.
She expressed interest in Sullivan having sex with Yasaka.
"Aunt, what are you doing here now?!"
Sullivan was shocked too see her after he had done fucking Yasaka, but he quickly calmed down.
He didn't know what his aunt was doing here now, but he couldn't help but feel embarrassed.
His aunt smiled before going straight to grab his cock and stroke it, causing his cock to harden again.
"What are you doing, auntie?!"
Sullivan never expected his aunt to do something like this.
"I've been wondering for a long time what it feels like to do that, but I never wanted to do that to anyone else until I saw you do that to the fox."
"Eh?"
Sullivan was confused and he understood. His aunt was a goddess and had never had sex with anyone before.
When he saw his nephew having sex with his wife, she started to want to try it.
For her, he should be good enough for her.
But aren't they both aunt and nephew?
"You don't have to think too much about us being aunt and nephew. We're not actually related by blood, we were just created by the lord father."
Sullivan gave a wry smile. He had only recently come to terms with his feelings about his harem.
This time, his aunt wanted to join his harem?
"You are such a thinker. Can't I join your harem just because I'm your aunt? I know what type of woman you like, you're just blinded by your common sense. Let loose and do to me what you did to her."
Gabriel said it as if it were normal. Sullivan understood that she had no common sense.
He looked at his aunt's soft hands, she was starting to perform sextual actions on him, and he couldn't refuse her anymore, as he had released his semen onto her hands after she had jerked him off.
"So, this is my nephew's semen…"
Gabriel was curious and ate it. She felt that the taste was quite delicious.
Gabriel then pushed Sullivan down onto his bed before she mounted him.
His cock was extremely hard and it was touching her panties.
"Aunt"
"Let this aunt handle it herself. Just lie still."
Gabriel immediately thrust his cock into her pussy. Sullivan's cock was able to penetrate her vagina.
It was the first time Gabriel felt this way. She blushed and felt weak. She collapsed into Sullivan's arms before taking a deep, lustful breath.
"Fuck your aunt, Sullivan. Treat her like that fox."
Gabriel asked for it and when Sullivan heard it, he gave it to her.
He fucked her in cowboy position. His fucking was really amazing for her.
Sullivan fucked her until he was about to cum. Gabriel knew he was about to cum and tried to put her womb against his cock.
"Don't pull it out. Come inside your aunt. Come inside me!"
Sullivan hugged Gabriel tightly before he came inside her, making her belly bulge like the Yasaka he had fucked earlier.
Sullivan fucked his aunt and it felt so good.
Sullivan didn't know that while he was fucking his aunt and Yasaka, Rias and Akeno, along with everyone else who wanted to join his harem, were masturbating.
Everyone heard the sound of him fucking Yasaka and Gabriel.
