As Katy and Cal walked into the door, both of them knew something was odd with the three waiting for them. Cal closed the door.
Mark asked, "You went out in that? I hope you made them use a condom."
Katy smiled, "He did. He was very popular. He makes a fine spandex slut for the guys."
Karen looked at Jim, and shook her head, "That's your son."
Both Karen and Jim were covered in bath robes, but had human legs, feet, heads, arms, and hands.
Both Katy and Cal walked over to the couch. Cal looked over to Mark, "What did you do?"
Mark gave a loud laugh.
Jim spoke up, "What makes you think Mark did anything son? I told you I liked the form I had. But you were right about being able to go to work. And your mom was freaked out when she saw me and Mark here."
Karen join in, "It will be hard to shock me after tonight."
Jim stood up, and turned to Katy and Cal, and slipped off the robe. Staring at them was a human male with the reproductive parts of an anthro canine hermaphrodite.
Cal noted "You kept both parts, that's cheating."
Karen stood up and dropped her robe, revealing a matching canine herm's organs.
Mark stood up, showing that he was now a herm too.
Cal looked unhappy, "Mark, not you too..."
Mark walked over to Cal, "I can fix you too. You'll like having a cock again."
Cal looks up to Mark, "I was fine with me being the bitch and you as my alpha male. How does it work if we are all herms?"
Jim and Karen look at each other, then Jim says to Mark, "You handle this one, we are off to bed. Thanks again boy." Cal watches as his parents walk off to their bedroom, noticing the tails that each one has.
Mark smiles, "Oh yea, they love the tails."
Katy gets up, "I'll leave you two alone. I had fun tonight Cal. Thanks," as she makes her back to her bedroom.
Mark sits down beside Cal, "Your mom was a very pretty Collie. I had a tough time getting your Dad to let me change him, but your mom put him in his place. She liked his idea of being herms, but not anthros."
Cal turns to Mark, "I thought we were a couple Mark. You with the cock and me with the pussy. Your way doesn't feel like that."
Mark responds, "Your parents don't think so."
Cal sighs, "And I don't like sharing you."
Mark grins, "That's the human talking. You know canines aren't monogamous. How many men did you screw tonight?"
Cal turns from anger to embarrassment, "seven" he says softly.
"Your my little slut Cal, and I am OK with that." says a proud Mark.
Cal wraps his arms around Mark. Mark answers by wrapping his arms around Cal. "I want to get married and have kids, and live a normal life Mark. And since we have changed, I want to marry you, and to have our kids."
Mark sighs, "You got a strong dose of the maternal instinct. It's made you think like a woman."
"Mark, I love you, and I want to be with you the rest of our lives. I feel that we won't be that strong together if we are both the same." says a depressed Cal.
"Hey, I will always be at your side. I want you to have our kids. This way, I can help. And if you change your mind and wanted to change back, you would have your cock." notes Mark, trying to persuade his dear friend.
"You promise me?" states a serious Cal.
Mark looks into Cal's eyes, and says, "Forever, it's us first."
Cal nods his head, and sighs, "OK." and then smiles to ask "I see you all three got nearly the same thing. Did the suggestion idea work before removing the collar?"
Mark shakes his head, "No, it wasn't that easy, but there was a lot of trial and error experimentation. Let's go back to your room and I will show you. We have a all night to get it right."
Cal gets up, "So you can reverse it too?"
Mark nods, "Sure can."
Cal thinks, "Make me an anthro dog like my dad was, since we will be experimenting."
Mark shows Cal his human feet with his canine paw pads, "Just a little something." Mark stands up and follows Cal back to his bedroom.
