Jon had returned, diaper in hand. He was babbling away to Biff as he came back in but Biff didn't really know what he was saying. He didn't want to push it with Jon so he just kind of went with it. Jon climbed back onto the bed beside Biff and lay on his back. Biff took the diaper and sat up onto his knees. He pushed his hair behind his ears. As he reached over Jon his breasts swung low over Jon's face and Jon had to fight the urge to grab them. When biff straightened back up he placed the diaper down beside himself and adjusted the hem of his nightie to cover his panties a little bit. As he did this Jon caught sight of his panties and noticed the smoothness of them and the lack of a bulge. Jon asked Biff, "Did you change more Biff? Are you a woman now?" but it actually came out as, "Mommy, you girl now?" It was hard to get the tone of voice to sound like a question as everything Jon said now came out as a sort of chirpy squeek but Biff understood enough. Biff looked down at Jon and in his own softer voice said, "That's right honey, Mommy is all woman now."
Biff soon had Jon's diaper removed and was wiping him clean. As he wiped around Jon's penis, he was sadly reminded of his own changed anatomy. He squirmed slightly on his butt when he thought about it feeling the empty void in his panties once again. Not wanting to risk Jon wetting the bed, Biff soon had a clean diaper fastened on to him. It was a warm morning so he decided to leave Jon in just a diaper for now.
Biff didn't have much planned for today so he decided to just put on something comfortable to laze around for the morning. He was supposed to go to Laura's at 5 so he wouldn't have to get dresssmed up until 4pm or so. He stood up from the bed and stretched his arms high above his head. Jon took this opportunity to study Biff's body further. Then his arms went up they pressed his breasts together, creating a substantial cleavage inside his nightie. The bottom of the nightie also stretched up giving Jon a clear view of Biff's panties, the front of which were smooth and followed the curve of his crotch before disappearing neatly between his legs. Biff felt comfortable around Jon. They were in this mess together and had been growing closer all week. Biff grabbed the bottom of his nightie and pulled it up over his head. He sauntered over to his dresser in just his panties, with his butt rocking back and forth with each step. Biff pulled out a matching black bra and panty set. He placed them on top of the dresser and pulled his panties down his legs, keeping his back to Jon for now. He stepped out of the panties giving Jon a brief look at his bare ass. Jon was amazed at how round and juicy it looked. Biff pulled up the clean pair of panties and pulled them up tight over his ass and around his hips. Next he put the bra, something he hadn't gotten much quicker at.
Jon was loving the show. He felt his penis stiffen at the sight of Biff in his undeniably female body, casually walking around in a bra and panties. Jon was for once thankful for the diaper as the padding hid his erection. He casually reached down and gave it a quick rub through the front of the diaper. Biff didn't seem to notice as he was busy looking for an outfit.
In the past a casual outfit for Biff would be a pair of shorts and a t shirt but he didn't have too many options in that respect. He didn't really want to wear any jeans or shorts as akk the ones he had available now were in a female cut and would have shown his smooth crotch to the whole world. Instead he settled on a casual sundress. It was very simple, a dark blue colour and would come down to just above his knees. He wasn't quite ready to put it on so instead he sat down cross legged on the bed , wanting to talk to Jon first.
