Amy decided she needed a hot tub.
Naturally, the whole group shows up to break it in. Even Katie, whose sexual tension with Marcus leads to something else being broken in, and a few mischievous voyeurs enjoying the show.

After what happened at the concert, and the rollercoaster of sexual exploration Tessa never thought she'd experience in her wildest fantasies, they start planning a bucket list (like group sex every weekend wasn't exciting enough). And although they've each got their own ideas of what's worth chasing, it's only fair that Amy goes first, after buying them all a hot tub.
