From one slide, down another (HR) (Patreon)

At the bottom of this water slide a second slide awaits you!  Instead of cold, hard metal its soft moist flesh. At the very end of this second slide there's a nice heated 'sauna' to relax in for a while, possibly a long while!

Raeth-rex is a friendly sort as we know, so how long your stay will be is totally up to viewer interpretation, as well as whether you digest or not.
