Jess was about to push the other girl away but instead of pushing her hands stopped on the girls hips as she grabbed them and then started returning the kiss.
While they were kissing she heard a girl say "It looks like the cow has a new girlfriend" but it did not bother her.
It just so happens that the boy with the Chronivac had made Jess want to return the kiss and was about to do something else when he also heard what the girl had said and smiled as he started making another change.
Jess continued kissing the other girl not caring as she felt her breasts getting even bigger and then with every squeeze her kisser made her shirt got soaked with milk.
They continued kissing for a while until the other girl broke the kiss as she said "See you later" then she looked down at Jess's breasts, "but I think you need to get to the cafeteria."
Jess finally looked down at her shirt which was soaked so badly that it had become transparent. She reached up at her new milk filled H cup breasts and knew that whoever had the Chronivac must be using it.
