The witch was named Viena. She came to the city of Trihea to find rare herbs and ingredients from the dungeon.
Obviously as a high ranking witch she was very proud. She also came from a more developed and bigger nation so she was quite dismissive of the city.
But then inside the dungeon she met with strong adventurers and had her first taste of awesome dicks. She found that experience to be noble but nothing more than that and was even planning to punish those insolent adventurers if she got the chance.
But that chance never came instead Viena got fucked almost everyday. Soon she had become addicted to those amazing dicks.
But then suddenly, those adventurers stopped coming to fuck her. This made Viena almost mad with lust and desire. Finally her pride lost to her lust.
She went to various adventurers who had previously fucked her, but got a cold shoulder from them. Seeing her sad and despairing expression one kind soul asked her to come to a certain room that night.
Viena really wanted to go back to her previous relationship with the adventurers so she went there right on time and found all the adventurers who had fucked her their with new ones too.
There she was told that, in order to get the adventurers' dick she needs to become their sex slave. Obviously Viena was not willing to do it.
But all the adventurers then took out their dicks and the scent of it made Viena go into overdrive. Her pussy was flooding with juice and her mouth was leaking saliva.
Soon she once again felt her insides being filled with the dicks. It was such a comfortable feeling that she felt like it was her natural state.
So when she heard that by becoming their sex slave she would be able to enjoy such bliss everyday and she would get many comrades, her pupils turned heart shaped and she accepted their proposal. Viena became a slutty witch and she also used her great talent to create many perverted pills and potions.
The adventurers who were the part of the family never need to buy any potion and they all could use Viena's potion for free. But there were still quite a few adventurers, especially male adventurers who were not part of the big group and they also needed potions and other medicines.
So for them, Viena officially gave some potions to the guild, and Vivian was tasked with bringing them to the guild.
-----
After reaching where Viena was living Vivian knocked on her doors and declared -
"I'm Vivian, an adventurer guild receptionist. I'm here to collect potions for the guild."
After waiting for a moment the door of the house opened slightly and a violet eye peered at Vivian. As soon as their eyes met both of them immediately understood that they were comrade and part of the same group.
Any type of suspicion disappeared from the eyes. The door opened a little more and a sultry voice told her to come in. Vivian entered the house without hesitation and the door closed behind her.
Upon entering the house a strong scent of herbs and medicine entered Vivian's nose. But that scent was mixed with the smell of sex. Vivian really liked this special perfume.
Then when she looked forward, she saw a beautiful dark skinned lady was getting fucked from behind by a strong looking man. This man beckoned Vivian to come to him with his hands and she obediently followed his order and went to him.
Then this man hugged Vivian with one hand and started to play with her boobs while kidding her. Vivian kissed him back and pressed her body tighter with him.
Then the man gave Viena a creampie and took his dick out of her pussy and told Vivian to taste the dick juice from Viena's pussy.
Vivian did as she was told and started to eat Viena's pussy while sitting down. Taking this chance, the man penetrated her pussy and gave Vivian a good pounding while she was busy tasting the cock milk. Then the man left after giving two tight slaps to both Vivian and Viena.
-----
After the session together Vivian and Viena had become very close. Currently a naked Vivian was lying on a naked Viena's lap while drinking her breast milk. Viena was also giving her pussy some rubs while letting her drink from her milkers.
"So Vivi chan, will you help me with it ?"
"Sure, sister Viena."
Actually Viena had just created a drug that could make a woman produce milk. She had tested it on herself and it was successful but she needed data from more girls. She was also trying to see if the produced milk would have the same or different taste depending on a person.
Vivian got injected with the drug and Viena started to suck on her nipples. Soon Vivian started to leak milk from her boobs. After testing it she found the taste to be different from her own.
So to be doubly sure, she asked Vivian to taste her own milk. Vivian took her nipples in her mouth and tasted it and exclaimed -
"Wow, it's really different. Your milk had a more complex and sophisticated taste to it but my milk is a lot sweeter."
"Hmm, that's interesting. I guess the taste really depends on the individual themselves. Let me call some guys to check it just in case. Just wait a bit, okay Vivi chan."
Then Viena went to use a magic item to ask the guild to send a few men over. It was a deal she had with the adventurer guild. Soon four men appeared.
Four of them took turns to taste all four nipples and gave their honest impression of the milk. They also took some with them to share it with other adventurers. Then after releasing their own cock milk inside both girl's pussies, they left.
Viena quickly wrote down the experiment results and asked Vivian for a favour. She had a researcher friend in the city who was also an alchemist like her.
This girl was also their comrade and a sloven hussy. So she wanted Vivian to go to her and hand this experiment result to her. Viena had more items to make, so she did not have the time right now. Vivian had reason to reject the request and accepted it.
Then she left witch Viena's house with a magic spacial bag filled with potions. She first went to the adventurer guild to report to the guild master about the completion of the assignment. Then after delivering the potion and getting her ass pounded by the guild master she left the guild to visit researcher Laura.
