Ria and Billie were watching the two girls as the one was getting felt up by the sales lady. When they saw the girl called Macy walk up and continue playing with her friend's breasts they smiled, but when Macy started sucking on Jess's tit Billie said "I have an idea."
Billie took the device and made a change to Jess so that her breasts filled up with milk. Ria was about to ask what she was doing when she saw the breast Macy was squeezing start to squirt milk all over the place.
At that moment Jess let out a loud moan before getting out a forced "you're making a mess," but her hand went to Macy's head, holding it to her tit so she had to continue sucking.
Both Ria and Billie were enjoying the show when the saleslady came back in. When she started to talk Billie hit enter on the device again only for the saleslady to say "When your finished milking that cow of yours I have brought you some bras that should make her look better."
At that the saleslady looked on as she thought "it's going to be another long clean up session."
Ria and Billie continued watching until Marcy had finished draining Jess's tit as they thought of what to do next.
