My post featuring Miss Nikki in her schoolgirl uniform received a great response so I felt I obliged to put her in another situation.
I kept things nice and simple, wanting to put the emphasis on the connection between her and her 'teacher'.
I went back-and-forth on Nikki's headgear trying gags and blindfolds until settling on her gas mask for the definitive version as it played against the title giving the silhouette of a puppy's muzzle. I couldn't resist going for full heavy rubber for both ladies in the final alternative version.
Fun to draw - the final version as seen here I actually flipped the whole image at the last minute as it felt like it gave 'teach' more dominance in the scene.
