This page is for the Cowsandra Conspiracy route, which means that Cass is a "willing" (read: coereced) slave and you use the milk pumps on her.

The scene you describe is part of the submissive route where, if you're Rosa and obtain them, Cassandra will use them on you (though I don't remember why or how often).

Note: to get the milk pumps, you need a willing slave Cassandra or be on the submissive route as Rosa.

The scene you outlined is exclusive to Rosa, it is not possible to access as Dan (unless you grab a gender change potion).
