Well, if you know the game, you already know the plot. But finding it out the first time you played through, without cheats ... talk about your slap in the face.
There are NO watersports in this chapter. Don't complain about the code not being included. Seduction of someone with their pants down that just used the bathroom - yes. That's different.
Seriously, one thing that the modded version of Skyrim had that I played when I wrote Legacy of a Legend was bodily functions. Your character (and the NPC's) would every so often quite literally have to go. Which seriously brought back the old rhyme to me.
In days of old,
When Knights were bold,
And toilets weren't invented,
You left your load,
Beside the road,
And walked away, contented.
Yeah, I know - pretty crappy, right? [rimshot}
