A violent ripple went through the K9 penis. I felt the pump-like motion first at my lips before I sensed how the girth of his cock expanded ever so slightly. The swelling sensation in my throat continued through the whole shaft until it reached the tip of the pointy meat tool. An avalanche of canine semen exploded from the hard cock and started to paint my insides white. 'ARGHMGMMG!', I groaned when the hot substance touched the inner walls of my throat. The real thing was nothing like the pre-cum fluid that Black had forced me to experience earlier. I felt my forehead glistening from sweat immediately due to the heat.
