Karyn just studied Jon. He wasn't at all embarrassed about having just used his diaper in front of her. It was perfectly normal for him to be sitting here on his bed in just a t shirt and a very girly, pink diaper.
"So what do you wanna do Karyn?" Jon asked while casually rubbing the front of his diaper. Karyn thought about it for a minute and suggested they just play some video games while they waited for dinner. Jon was keen and he jumped up off the bed to turn on his console. He picked up a controller and was walking back to hand it to Karyn when he paused for a second. Karyn watched Jon squatting down and grunting ever so slightly. She knew he was using his diaper once again, this time pooping in it most likely but Jon didn't seem to be giving it any thought. He quickly stood up again and handed Karyn the controller. As the game loaded up Jon sat down again beside Karyn.
"Hey Jon, did you just use your diaper again?" she asked him, holding back a smile. Jon just shrugged his shoulders and said, "I dunno Karyn. Don't think so. Cmon, let's play."
They played a round of a fighting game but Karyn couldn't concentrate. She was starting to get a faint smell coming from Jon. She decided to press the issue with him. "Eh Jon. I think you might have done a poop. I can smell it."
Jon paused the game and felt around the back of his diaper. He didn't miss a beat and just said, "Yeah, I think your right. I pooped. Just gimme a minute, I'll get changed."
Jon grabbed a clean diaper and a pair of wipes from his dresser and lay down on the floor beside Karyn. He didn't think it at all odd to be doing this in front of a friend. Karyn asked if he needed a hand but he refused saying," I can manage. I'm a big boy Karyn. Not a baby."
Jon removed his diaper and wiped himself all over. Karyn was grossed out by it so turned away. While Jon was distracted she pulled out the device again and looked through the options. She found a menu for changing people's minds. She saw an option for arousal and decided to ramp up Jon's arousal as well as he own. With a few presses of buttons she had fired the device at BOTH Jon and herself, increasing both of their states of arousal by about 50%. She turned back to look at Jon. He had cleaned himself and was putting a clean diaper under his butt and starting to close it. She saw Jon's dick had grown extremely hard since her latest alteration. She also felt her own arousal increasing and couldn't take her eyes off his boner. She felt her nipples growing hard inside her bra and was now finding it hard to concentrate on anything except Jon.
Jon had finished putting on his clean diaper and had tidied everything away. Karyn caught his eye and the two teens stared at each other for couple of seconds. Karyn started to flirt with Jon a little bit. "Jon, that diaper is so cute. It makes you look really handsome." She leaned back on the bed and adjusted her top a little bit to make it better show off her impressive breasts. Jon just stared at her. He was standing up now and had a very clear bulge in the front of his diaper. He walked slowly back over to the bed and sat down beside Karyn, his diaper making a crinkling sound as he did. Karyn leaned over towards Jon and ran her hand up his bare leg, stopping just below the elastic leg hole of his diaper. Jon just sighed a lustful sigh and leaned in towards Karyn. Their eyes met again and in seconds they were passionately kissing. Jon moved one of his hands up to squeeze and rub Karyns breasts through her top. He took his other hand and grabbed Karyn's hand an dolaced it right on top of his diaper, right where his erection was straining against the thick padding. Karyn started to squeeze and rub Jon's dick through his diaper and then leaned back further so she was lying on the bed. Jon adjusted himself so that he was lying on top of Karyn. She opened her legs slightly to make it more comfortable for Jon and he was now leaning over her on his knees. Jon started to dry hump Karyn on the bed, the soft material of the diaper rubbing against Karyns pants. It made a crinkling sound with each thrust Jon made. He sped up a bit and kept kissing Karyn. Jon could feel an orgasm building quickly. He didn't know it but his lack of toilet control also meant he couldn't really do anything to hold back an orgasm. Jon didn't worry about it. He just continued humping Karyn at this pace and after a few seconds he felt himself explode in orgasm and filled his diaper.
