They take it to the upstairs common area.

Mary didn't even wait for Maria's help in undressing Catarina before pinning her against a fainting couch with her body. Her own exposed breasts squished against Catarina's covered ones. Both hands cupped said breasts as their kiss broke, and Mary moved her lips onto Catarina's neck.

Lady Hunt tugged at Catarina's dress a few times, finally managing to hike up her skirt enough to expose her stockings, her garterbelt, and the exposed womanhood between her legs. She grabbed the middle-finger of her glove by her teeth and tugged it off. Hand free, she reached down, and brushed her fingers across her clit. Pleased with the noises Catarina was making, she slid a finger inside her.

Maria stood by, her face red, thighs rubbing together, struggling to keep from touching herself, lest Anne, standing next to her, admonish her for it.
