It had been three weeks. Selina as been going back to the city two times a week to get what she would need to make more of the chemical formula to use wanting to change others into cat women by other means than sex. She had made some more and tested it on a male mountion lion that got out of the zoo a week ago which she caught. It had turned into a female anthro lion with six boobs which she then had mated and impregnated by a male human who was changed into a futa by the new breeder's cum. Selina had learned by it that the formula turns males into breeders and females into futas while their cum will the opposite, males into futas and females into breeders
She was on her way back when she saw two girls being knocked out in a alleyway and taken to a van by four men. She decided to take the girls and dropped down and attacked the men with her claws cutting the off the head of one and a arm of another. The other two tried to fight back but were too slow as she bit the neck of one and tore it off and slabbed the other in the heart with her claws. She killed the one who she cut his arm off and took the women with her to the Den as she been calling the bunker. She put away what she got and found May the new futa. "Which one do you want?" Selina asked her. "I'll take the blonde." May replied after she saw Selina eyeing the other one who had blue hair knowing that Selina wants to turn the two girls into new breeders.
The two took the girls to the breeding room. Selina picked up a pair of injectors off a table. The chemical formula in them is to make the girls horny. After that they were injected they were tied up and their clothes removed before smelling salts were used to wake them up. "What the? Where?" The blond girl said waking up and found herself tied down. Her panic woke up the other who had blue hair. "What? Yang what going on?" She asked her friend. "I don't know Dawn I just found myself like this." Yang answered her. Dawn then saw the two cat women. "What the hell are you?!" She said drawing Yang's attention to them. "Your new mates." Selina said as she and May walked up to the human's faces. They took their cocks and thrust them in the girls' mouths.
The cat women fucked the girls' faces for several minutes before they came in their mouths. Dawn and Yang were dazed from the musk of the cat women's cum and are now horny. "Well want us to mate you two?" May asked them. "YES!" Both of them said that the same time. The two cats went to their chosen girl's pussy and thrust in."OH!" "AH!" The two girls moaned. May thrust in fast making Yang scream in pleasure. Dawn was moaning from the hard slow thrusts from Selina. The women were thrusting into the girls who are now enjoying being mated and started to grow fur. The two girls were cut free with Dawn on her legs and arms being taken from behind. Yang was on her back and thrust up into with May rubbing and biting her breasts. The cats thrust harder and faster hitting the wombs of both girls who's their new boobs were growing. The new breeders had finished changing when their wombs were violated by a hard thrust and cummed in being impregnated. "NYA!" "OHH!" They black out after that. They were moved to a new rooms and place on the beds.
Hours later Selina had finished making more of the formula in gas form and made a bomb that lets out the gas. Now were to use it?
