Not wanting to be seen drinking beer by the person at the door Jon quickly put down his beer. At the same time Biff put his own down and got up from the couch to open the door. Biff and Jon recognised the delivery man, it was another one of Biff's old friends, Moose, who must be delivering pizzas in the evenings after school. Moose didn't show any sign of recognising Biff or Jon. He simply greeted Biff and said he had a pizza delivery. As he was saying this he was staring fairly obviously at Biff's chest. The fact that Biff was not wearing a bra must have heightened Moose's attraction to that part of Biff.
Feeling a bit of a buzz from the beers, Biff forgot himself for a moment and seeing the effect he was having on Moose he smiled at him and with a breathy tone said, "Oh silly me, I should have had the money ready. Just a second, my purse is around here somewhere." Moose wasn't complaining. He didn't mind things taking a bit longer if he get more time to get a look at what he saw as a hot woman. Biff saw his handbag on the ground at the bottom of the stairs. He had flung it there in his enthusiasm to get changed when they got home. He bent down at the waist to fish his purse out. He had his back to Moose and Moose had his eyes glued to Biff's butt which was stretching the material of his track pants to their limits. Jon watched on from the couch. He could see Moose standing, slack jawed staring at Biff as he rummaged through the bag. Standing back up, Biff turned around quickly with his purse in hand. Moose quickly adjusted his gaze as Biff started to get his money out. Biff handed him a twenty dollar bill and said, "You can keep the change honey. Thanks." Moose muttered his thanks and turned to leave, trying to discreetly adjust the boner that had sprung up in his pants at the sight of Biff.
Biff closed the door with a sigh of relief. His hips swayed as he walked into the sitting room holding the pizza like a waitress holding a tray in one hand. He placed the box down on the coffee table between him and Jon, opened the lid and handed Jon a slice. Biff grabbed a slice for himself and sat back down demurely. His legs were crossed and he was carefully taking small bites of the pizza being careful not to drop any of it on his clothes. Jon started eating his pizza, very quickly, his hunger amplified by the beers he had drank. He wasn't being as careful as Biff and a piece of pepperoni fell off the slice and landed right on the crotch of Jon's diaper. Jon barely paid it any attention and continued eating the slice, even getting some sauce on his face around his mouth. Seeing the mess Jon was making, Biff picked up a napkin and wet the end of it with his tongue before leaning over and wiping Jon's face with it. Neither thought much of it, nor did they think too much of it when Biff reached down and grabbed the slice of pepperoni from the front of Jon's diaper. Noticing the bulging front of the diaper, Biff said, "Wow, Jon. You've really filled that diaper up again. Must be all the beer. Let me know when it gets uncomfortable and I'll change you again." Jon just thanked him and turned his focus back to the TV.
The pizza didn't last long and as Biff finished his beer he excused himself to go to the bathroom. Jon stood up off the couch to grab his beer and remained standing for a moment, focused again on the tv.
When Biff came back in he saw Jon standing, slightly squatted with a look of concentration on his face. He approached Jon and heard a quiet grunt come from Jon. "Jon, are you ok? Did you just go in your diaper again?" Biff asked quietly. Jon didn't even realise what he was doing but now that Biff mentioned it he knew he was right. Jon looked up at Biff, embarrassed again and simply nodded his head. Biff told him not to worry and before Jon could even get upset Biff had him on his back and quickly removed the diaper. He cleaned Jon and got him into a clean diaper without saying another word. They both sat back on the couch and settled back into their watching, with a fresh beer each that Biff had brought them. When Biff finished this beer he looked over at Jon and saw that Jon had fallen asleep on the couch. He turned off the TV and gently woke Jon so that he could guide him up to bed. He left him in the t shirt he was wearing and helped him in to bed. On instinct he gave Jon a kiss on the cheek. Sleepily, Jon said "Goodnight mummy. Love you." Biff felt his heart flutter as he stepped out of the room.
Biff headed for his own room and took off his clothes, including his underwear. His inhibitions were gone as he was kind of drunk now. He was trying to decide what to wear to bed but he wasn't as determined as he had been earlier. The feminine thoughts he'd been fighting had become louder and giving in to them he quickly selected a pair of panties and a matching baby doll nightie which he put on like a t shirt. Biff was about to get in to bed when he felt the urge to pee again. He made his way into the bathroom and stood at the toilet. He reached down and grabbed the lacy bottom of the nightie and pulled it up. With his other hand he pulled the waistband of his panties and pulled out his penis. He stood and did his business while giggling to himself. How ridiculous he must have looked, peeing the way he was but wearing such a feminine outfit.
Finishing up in the bathroom Biff checked that Jon was ok on his way back to his own bed, where he crawled under the covers and was asleep almost as soon as he put his head on the pillow.
