This image is taken from a gallery entitled ‘Psych Ward’. A better title might have been ‘Plumbing and pipe fitting around the home – it’s easier than you might think.’ That is one large sound. And, without meaning to give offense to the model involved, not a particularly enormous penis to accept it. Although its possibly just being dwarfed by the hardware deployed.
The image is taken from this image and clip collection on the k is for kink site. The domme wielding the sound is Mona Rogers.
