This should really include 'forced' tag. The woman are constantly telling this guy 'no', but this guy just gets off for himself. The description made me think this was all going to be voluntary. This is the second time I've been burned by inadequate descriptions.
It is quite forceful a the start, almost disturbingly so, but I am a fan of the setting and the art is pretty good. I kind of want to see where this is going.
