"Welcome back to Build-a-Babe miss."
"Thanks! How's she doing?"
"She's nearly integrated. It's just her head left to assimilate, then your new mannequin-babe will be ready for you to collect."
"Just the head? She finished faster than I thought."
"Well, she was rather eager to have her new body. That helps the process along."
"Even when the changes are so substantial?"
"We find it's especially fast in these cases. The new object knows what it wants, and are happy to cast of their old body."
"I guess I can see that. Still, I'll miss the sex."
"We've got a record of get old body. Would you like a silicone copy?"
"Wouldn't that be disrespectful to my new girlfriend?"
"She's a toy now. She can't/won't care."
"Huh... Nah. Though can I see some other hunks to get a doll of?"
"Certainly, this one will be inanimate though, unless you know if other willing materials."
"Inanimate is fine."
"Right this way, by the time you're done picking your doll, your mannequin should be finished."
