as mark finishes his transformation into a great dane he feels a lick at his new rear end.
"Dont do this boy..." Mark Barks
"But you wanna be best friends forever right?" butler responds
"not like this!" Mark Barks in disgust
"dont worry, ull like it soon enough" butler wispers in your ear.
Butler then proceeds to move around to your ass where your moist cunt stares him in the face. with a large jump the great dane slides his body over his former master.
"are you ready Mark?" asks butler before slamming his 7" doggie cock deep inside the awaiting Great Dane Bitch.
"Noo!!.... oh.... butler.. thats... fantastic..... UGH.." Mark begins to feel the thrusts going deeper and deeper into her cunt. "ugh... nice.... more... i want more!" screams mark pushing his ass back into butlers crutch.
"see thats ... ugghh.. the spirit... ugh.. now TAKE MY SEED BITCH!" and with that butler removes his cock completely from mark only to slam it back into her until it is fully hilted into her cunt
Mark groans as she feels the seed spread to her womb.. undoubtably starting her pregnancy.
"thats it! we shall start a family together mark.. you and your best MATE forever" and with that the collar that was around marks neck changed to look the same as butlers.. with a new dog tag that read "Maid"
