In 1975, Severus was unfortunately attacked at the Shrieking Shack and transformed into a werewolf. His embarrassing new identity leaves him with only one choice: to become Lucius Malfoy's dog, trading his dignity and future for survival and revenge. Faced with this situation, as an opportunist, Lucius naturally decided to temporarily abandon racial discrimination and instead use it to attack political opponents in order to maximize his profits - what he meant was that as Severus's sponsor and guardian, he wanted to seek justice for his boy - and Narcissa supported him 100%. In fact, as long as she didn't need to exchange her life for Malfoy's son according to the marriage contract, she didn't care even if the other father of the Malfoy heir was a dog.
So, this was the beginning of the plastic relationship between the three of them.
Warning: It's a threesome between a man and a woman, and the rest of the CP is the same as the original. Contains a large number of secondary designs and essential magical creature literature. If you don't wash the snake, you won't be a black lion, but there are circumstances where decent people are being persecuted. If you feel it is biased, please point it out. I am deeply influenced by the otaku and notwolf, so any similarities are entirely my fault.
Premise: Malfoy has serpent blood flowing in his body, which makes their reproduction process a completely different form of asexual reproduction from humans. This process requires the participation of at least three people without causing casualties.
Narcissa was engaged to Lucius in 64, and they married in 73. According to the marriage contract, she would be another mother to Lucius Malfoy's son. Severus accepted Lucius's patronage in 72 AD. According to the sponsorship contract, he would be another father to Lucius Malfoy's son.
Purpose: Blood discrimination is unacceptable
