Pete found Biff, Jon and Karyn in Biff's room. The 2 babies had been changed and were both sitting patiently watching Biff get himself ready. His dress had gotten food all over it from dealing with the mess Jon and Karyn had created so he had take that off. He now stood in his bra and panties, looking in his closet for a new dress to wear to the mall. It was warm outside so he wanted something summery and not too heavy. He had just made his selection of a long summer dress with a floral pattern and very short sleeves. Taking it off its hanger he turned around just as Pete came in to the room.
Under normal circumstances Biff wouldn't have been caught dead being seen standing around in women's underwear but in his current role he was just a young mother getting dressed in front of his 3 daughters. He didn't even feel the need to hurry up and cover himself. He took his time, laying his chosen dress out on his bed while talking to Pete.
"That's a lovely outfit honey," Biff said to Pete as he adjusted his own bra straps to make it more comfortable. He stepped into his dress and pulled it up over his shoulders. It had a zip on the side which made it cling to his side and another zip at the back which made the top sit snuggly on his back and shoulder. Pulling up the hem and adjusting his panties he turned his back to Pete and asked him to help him close the back zipper. Pete was happy to help and as Biff dropped the dress back down Pete ran his hands along the smooth material and down across Biff's butt, making sure the dress wasn't creased and looked OK.
Neither guy was embarrassed by the intimacy. Biff just thanked him and turned to Jon and Karyn and enthusiastically told them he was ready to go and asking them to be good girls for him in the mall.
