"Thanks a million guys. Great to know I can count on both of you." Biff said, a bit annoyed at both his supposed parents and at the situation. He turned to go to his room, intending to change himself.
"One of us better go with him," Sarah said to Jon. They were both worried he'd revert to a toddler again and who knew what that would lead to.
"He's your boyfriend," Jon said, "you must be used to touching his junk." Sarah was not impressed with what Jon was implying but she didn't want to argue. Jon's comment had not been very in character for a wife to say to her husband and he could feel his control starting to slip again. When Sarah reluctantly left the room to go after Biff, Jon figured he better do something motherly if he wanted to maintain control of himself. He finished his coffee and decided to make some snacks to bring to the playground. He never would have planned ahead like that and he hoped that would be enough like something his own mother would do to fight off his compulsions. Jon packed some fruit and some drinks into a tote bag and then washed the few dishes from their drinks. He was deliberately walking with a bit of a sway in his hips to cement his compliance. The tight panties riding a little bit up his butt was a constant reminder to him.
Not wanting to waste the entire day Jon went to find Biff and Sarah to see if they were nearly ready. He stood outside Biff's room to listen before going in. He could hear Sarah talking away to Biff but she was really talking to him like he was a baby. She was deliberately lowering the tone of her voice a bit too. Biff was just giggling and kept calling Sarah "Daddy". Jon went in to the room when it sounded like they were done. He saw Biff lying on his back with his dress pulled up around his waist. Sarah was kneeling beside him and had just finished closing a clean diaper around him. Biff was the first to see Jon come in and he out his hands up and shouted "Mommy" indicating he wanted Jon to pick him up.
Sarah and Biff both shook their heads for a second and their eyes seemed to focus again. Jon looked oddly at then both and Buff was first to speak. He told Jon they both found it too awkward to deal with the diaper as they were so they just let the compulsions take over and went through the motions on autopilot. They were both still aware of what they were doing but it no longer felt embarrassing or awkward, it was just the simple case of a father changing his daughters diaper.
Jon said he was glad they figured out a way to get passed the awkwardness and suggested they head to the nearest park so Biff could play for a while. Biff clapped his hands and said, "Yay. Playground. Playground." Jon and Sarah just looked at each other, neither one sure if he was choosing to act like that or not. Sarah took Jon by the hand and said, "C'mon babe. Let's go." Jon smiled at her and turned to leave the room and Sarah surprised him by playfully swatting him on the butt. Jon just looked back over his shoulder seeing a different side of Sarah. He felt like she was undressing him with her eyes. He put a bit of an extra wiggle into his hips as he walked away from her saying, "You coming or not, daddy?" Sarah felt a twitch in her pants, finding herself much more aroused and much quicker than she was used to.
Biff was standing at the front door, eagerly waiting for both of them. Jon spotted a large pushchair by the front door and suggested Biff get in. None of them knew exactly where they were living now or where the nearest park was so it made sense. A toddler as young as Biff wouldn't be able for too long of a walk. Biff eagerly got in and waited for Jon to strap him in. Jon needed Sarah's help manoeuvring the pushchair out the door and down the couple of steps outside their front door.
When they were all outside the house, Sarah looked around and said she recognised this street. She said she knew the way to the park and lead the way. Jon was happy to have someone taking control of the situation and he happily pushed Biff along in the pushchair, both excited and nervous about meeting some of their neighbours along the way.
