Began making the BDSM minigame (Patreon)

In the next release the game will have a BDSM minigame (only playable by the protagonist, at least for now), it is something that I had thought of in the past (hence the BDSM sexual stats) but never went too deep into it so the game design has actually nothing about it.

The reason is because I do not know anything about BDSM but I researched into it a bit recently and thought of a possible minigame fully knowing it will not be realistic.
I have started sketching the graphics... The "Darker" shade where the woman body stands will be a wooden platform, the straps at her feet are made of black leather, the background will be red curtains and those things attached on her wrists are ropes.

Once I finish sketching her head, I will clean it up, outline, color and shade as usual and then I will move to actually develop the minigame.
