Sean ground a little bit, as he reached under his loincloth and feel his leathery balls with the size of orange.
"Derrick, it feels so good to be here, isn't?" Something in Derricks mind tell him thats wrong, but a louder voice say, that is what it feels.
So both sit down and start eating the food that bull offer them.
Derrick eat a lot, but his dad eat more and it seams that he start to get more muscular while he eat so much food. Bull look like he smile, as he see sean to try to stand up. but it isn't possible for the now muscle man. all he can do is to go an all four. the loincloth doesn't fit the big muscle butt of him any more. And so Derrick could see the black leather ballsack of his father and the big dark human cock too.
Derrick don't know why, but it make him get an erection. He starts to rub his cock thru his loincloth. He shack his head. "What do i do" he think as he realize that he mustrubate by the view of his fathers balls and cock.
When he look to bull he see that the minotaur strip of his loincloth and stand with a full erect bull cock. it only take two steps of bull to stand behind Sean and pull up the rest of the backside of the Seans loincloth.
Sean begin to moo as the minotaur to stick a hooved finger in his hole. first in pain but than in lust.
Derrick couldn't belive what he see, but than he realize he mustrubate again. and he don't stop it. he see that his dad anus get black and big like a bull anus. He stand up and go to bull and his dad. he knee down and start licking the testical of Sean. Seans Moo get louder while he get more sexy crasy. Derrick could see another change on his dad ass. At the end of the spin directly above the his butt cracks a tail starts to grow. black and dick lick bulls tail. as it full grow, bull put his finger out of Sean and go to the front of Sean. He help the man to stand up.
"Wow", thats beautifull, Moo, i have my own tail. Do you see it son. do you see how good it looks?"
"Dad" shout Derrick out in panic. "You are not human anymore!!"
"Yes. Moo. I become a real man. Moo" Sean say enthusiastic. Derrick was shocked about the reaction of his father. But on the other way his father looks awesome now.
Bull look at Derrick and grount. But Derrick shook his head. He was not so far like is dad to become more bullish. So Bull look at Sean and moo to him. Sean knee down in front of bull and start licking the cock and ball of the minotaur. The minotaur start pre cumming and Sean lick it off the dick. Thats start an new change on him. his ears get longer and pointed, so that they look like bull ears. and thats not the only change. Sean stand up by a sign of bull and liftet his loin cloth.
Derrick look at his dad new bull sheath and the big bull testicals that hang low. Derrick feels a explosion in his own balls, as he shoot a big load of cum into his loincloth. That his dad become so bullish make him cum and wish he feel this dick in his mouth.
Bull snout again and his hand show to a fresh pile of hay.
Both, father and son walk over and lay down. it don't take long and the fell asleep.
In the morning Derrick is wake up by bull. he look around but couldn't see his father.
"Where is my dad" he ask the minotaur. but the only thing bull do is to put is arm up and sign to the other side of the cave. Derrick see that his father sit ther and mastrubate a bull dick, that his dads dick become to. he also get hard when he see that. he try to stand up, but bull hold him in place. With a loud Moo, Sean shoot a big load of cum over his upper body and chest. Bull leave Derrick alone and go to sean. he starts rub the cum of sean into the feet and toe of him. And Derrick could see that the toes of his dad fuse together into big cloven hooves.
"No dad, you have to stop him. he change you into a minotaur like himself" "Moo?" thats the only thing that came out of Seans mouth and Derrick knows that his dad lost his human voice. Derrick would try to stand up and leave the cave, but like the same that happen to his dad yesterday he couldn't stand up only stay on all four.
in horror he see that his dad get up on his new hooves and come to him, on his side bull. he can smell the fresh cum on this dad and get hard. he try to resist as his dad offer him his bull cock, but Derrick have no choice, he start lick his dads dick and taste the bull cum. than he feel that bull starts to manipulate his ass. he had tears in his eyes, because he know that he will have a bull anus and tail like his dad.
But he also know, that he would love it, same like his dad. It only take seconds, then he feel the change of his anus and feel his new tail. his dad take a step back from his son and Derrick blow his fist "Moo" to the world. he take the second step to his own way to be a minotaur.
He look up to his dad and see that his dad also change a little bit. the legs of his friend Sean, no that is his dad, become darker and fur starts to sproud.
he stand up and go to the table that bull bring in with lot of food. he start eating and couldn't stop. but that doesn't matter, the food make his muscle grows and soon he was a muscle beast like Sean.
they all rest for a while and than Sean bent over to Derrick and moo into his ears. that moo fill derricks mind with the wish to fuck sean. and he get hard again. As Sean see the passion in Derricks face he stand up, go to the middle of the cave, bent over and show Derrick his naked ass, he lift up his tail and so derrick has the good view to Seans bull anus.
Without to lost any time Derrick follow his dad with his hard not really human cock swipe arround from side to side. When he stand behind his dad, he push his hard cock into him. he fuck the man in front of him and don't realize that his cock change to a bull cock and that the man in front of him get the hind legs of a bull. And he forget that this was his father. He only remember, that this changing man is his friend Sean. He shoot a big load deep inside this man and than he pull his dick out of him.
he didn't hear that bull stand behind him, and when he go back the minotaur go behind sean and push his bull cock inside the bull ass of the young man. all below the waist of sean was that of a bull, nothing recognize that this looks human yesterday. Derrick go around the couple and see that Seans face change into a muzzle and he grow horns. When bull shoot his load into Sean, the change is fullfill. their are not a human fuck by a bull man, their are only two minotaurs.
