#396871 - The now constantly orgasming Dog vibrated and shook with every violent ejaculation he sprayed from his spasming organ, both his dong and the bulb that trapped it in my boy-womb bucked and writhed as if it were a separate creature imprisoned in my guts! My heart kept racing; I could feel each increasing blast of hot sperm pushing his foaming flood of Canine DNA deeper into my colon by the moment. I was cumming so hard all I could do was moan and flop every way my Dog-Master and his shaft pushed or pulled me, with each wave of ecstasy I added another load of milky-white goo to the puddle forming beneath my open legs. My heart thundered in my ears as I knew the Monster contained in me was threatening to erupt my asshole open and burst my flooded belly in two.
