Bun in the oven

As Karyn watched the dress that was here friend several days earlier the gloves, heels, and veil began to disappear into the dress which was slowly taking on a more pink hue. As she watched the train began to shorten and become a more cotton-like cloth. The sequins and lace began to dissolve, turning into flower patterns all over, the neckline began to recede, becoming a pair of straps. As the minutes went on she quickly watched as the wedding dress became a much simpler looking flower pattern sun dress. Taking a closer look she also noticed within the dress was a matching set of pink panties and a pink nursing bra. Looking at the choice of form questioningly she shrugged, stripping down and placing the clothing on her body once again.
"Karyn?" She heard Jon say.
"What's with the nursing bra Jon? Few better choices of underwear I could think of."
"Well..." Jon said pausing for a moment, "I wanted to try something, do you mind?"
"Go ahead, I trust you Jon."
No sooner had Karyn said that than she began to feel an odd sensation in her stomach. Standing in front of the mirror she watched as she stomach and breasts slowly began to balloon out, the realization of what Jon was doing slowly coming to her as she began to take on more and more of a maternal look. Sitting down on the bed as suddenly the weight change began to hit her it stopped, making her look to be a good 8 months into pregnancy, her breasts having swollen with milk in the process.
"This feels weird," Jon said.
"You're telling me, feels like I weigh a ton."
"I can feel it too Karyn, I'm literally tied to your senses."
