help! can't remember the title of this lewd manga! (4some between girl, brother, half wolf and cute guy)

[rlrl2603]

I read it around 2024, on pivix. It was by a Japanese artist. It's a foursome beautifully drawn lewd af manga and I can't remember the name for all that is good in the world. Please help! The story goes like this: In a world where people were reliant on magic, this girl couldn't conjure much. She has a hot af brother, not blood related and she befriends this hot half wolf guy later on. Later, a stranger did something which knocked the girl unconscious with a high fever. It was unveiled that her parents were a witch and demon (I think). The stranger unleashed the tremendous power inside the girl that was suppressed by her mother (possibly to keep her safe). There was a mark on her body that required the girl to receive semen or she'll die. So... in order for the fever to subside, her brother stepped in and gave her sweet nectar. Then the half wolf guy also helped out. It went on to be a threesome hehe. She needed sex everyday if not her fever would come back. As the story progressed, they visited a castle where this cute guy lives (I think he's a prince or something) to seek some magic books, in hopes of finding a cure/answers. While the cute guy and girl were studying, the girl's fever acted up again and she jumps the guy. More progression, and the brother, half wolf and cute guy came to an agreement where they'll help the girl because they love her. They have sweet sweet sex. But the next morning, the brother and cute guy woke up to find the half wolf guy almost half alive, coz the girl was taking a lot of nectar out of him. It was an ongoing manga so that's all the chapters released at the time. Please help if you know the title of this manga! Thank you
