A very interesting slug variant shaft beast.

I imagine the arms are completely retractable into those pussies. But the interesting concept here for me are the pussy-nipples. This is probably the first time I've seen them not atop female breasts. I imagine having them atop muscled pecs would make them several times tighter. Flexing/pumping such pecs must feel amazing.
