Skipping end credits enables extra sex position

Once the final scene is over and the end game credit appears as soon as you skip this, one of the elf queen special sex positions are available. What i did I went to the Chapter 10 mission start up screen and started sex like normal. Keep tabbing after the facesitting position and the sex position is available. Once you exit the mission screen the position isn't there anymore when you have sex with another npc. The position i'm referring to is the standing doggy position with the female laid right on a D-dub sofa/table.

Now in a way it's a cool cheat of sorts as this sex position is only selectable during the final elf queen romp so please d-dub if possible please have it available some how!
