Those two girls were brought at separate sales so they don’t know each other but their master has put the two of them together as they are destined to be show girls rather than bedroom slaves. Their function is to put on lesbian shows for their new owner and his friends but first they have to be turned into lesbians so they are leashed together and made to kiss. This is only the first part of their training, they’ll have to get used to being very intimate with each other before they get their own collar and leash.
