Cal returns to his room with the two glasses of orange juice. He wakes Mark, who is groggy, and slowly sits up. "I brought us orange juice. My sister is making coffee." Mark turns to Cal, and Cal reaches the glass over to him.
Mark gives a low, deep growl, and takes the glass. "Thank you"
Cal finishes his glass and climbs back into bed, next to Mark. "If your happy, I don't want to change again."
Mark waking up quickly after the glass of OJ says, "We have this time to share before Katy leaves. It might be best if we makes lots of changes to see what we like. Once Katy leaves, we can't change anymore."
Cal nods, "I saved the file. Just pick out what you want, and I'll adjust to fit. I trust you."
Mark nods back, "Thanks buddy. How about I change into a twin version of you?"
Cal nods, and Mark reaches over and puts on the collar, and slides off the bed, then steps over to the computer. Cal joins him with the dildo. A few minutes later, Cal is looking at Mark, and is unable to talk.
Cal's mom knocks on the door, "Breakfast is ready boys."
Both Cal and Mark laugh, as they don't fit the 'boys' description at all, but more like supermodel athletes who have hermaphrodite canine sex organs.
Mark followed Cal out of the bedroom and into the kitchen to sit down at the table. Cal's dad could not stop staring at the huge rack that the two busty women now possessed. Cal's mom and sister even could not stop staring.
Karen smiled at the two, "The two of you make a cute couple."
Katy asked, "Which one of you is Cal and which one is Mark.?"
The two former boys looked at each other and smiled. "And in unison said, "He's Mark, and I'm Cal."
The whole table erupted in laughter. Afterward, Karen said, "It doesn't matter, you ladies need breakfast." The table conversation was surreal to Cal, his family had never been as open to discuss such topics, and now it was ordinary.
At the end of Breakfast, Karen announces, "Kids, your father and I will be going a way for a couple of days. We have a lot of sex we need to work though. We will be back to spend a day with Katy before she goes back."
Mark smiles, "You can bet we well too."
After breakfast, Mark and Cal were in Katy's room, both were interested in swimsuits as they all three were heading to a local water park. None of them liked wearing clothes, but the tight, stretchy fabric felt almost as good as nothing at all.
