Zoe yelled from behind Jon, "We'll go too!" Before he realized it, Jon suddenly had no body; his head was pulled into the air by Zoe, and a moment later he felt an entirely new body underneath him. A little boy's body with a vagina and a woman's breasts which looked ridiculously large on "his" small frame. A made-up goth girl's head and a teen boy's head were together on "his" unnaturally wide shoulders.
"Zoe, Jon, that's so nice of you to come!" Their mom's head spoke from the strange body, as Zoe controlled their shared little boy body and put both Jon's arms from his old body under their current ones. What were his dad and his little sister Sally doing during all this?
He was distracted from these thoughts by the bouncing of his, their, enormous tits as Zoe took control and walked along behind Mom and Mikey. Zoe seemed completely relaxed, as if she wasn't currently a huge-breasted little boy with two heads and four arms, and Mom and Mikey were taking it just as well. Everyone stared as they went to the store, Mom/Mikey's lower arms wrapped around his/her waist while the upper pair drove, Zoe just keeping both sets of arms at their side. No one seemed particularly horrified; it was as if they'd seen it before but hadn't quite become used to it.
Zoe and Jon just walked along, occasionally grabbing things from the shelf and sneaking them into the basket, while Mom/Mikey grabbed things with all four hands and conversed. Jon just kept quiet. Everyone in the department store - they'd decided in the car not to go to the mall - was steering visibly clear of them, as if they could pluck things off their bodies as well. Jon was getting more and more embarrassed, and heaved a sigh of relief as they checked out and headed home.
