Nick fucked himself on Megan's dildo until he was utterly exhausted. He hadn't even noticed when Megan left the room. He'd quickly lost count of the number of times he had cum but finally he had to admit defeat. His legs were so worn out by that point that standing and walking to the bed were nearly impossible. He collapsed into an heap on the bed and didn't move.
Megan returned to the bedroom a little while later to check on Nick since she hadn't heard him moaning in pleasure in a little while. She had masturbated watching Nick fuck himself for nearly an hour before she had needed a break, but Nick had kept going not even acknowledging her when she'd returned later asking if he needed anything. The room smelled strongly of female arousal. The dimming light from the window was just enough for Megan to see her twin stretched out naked on the bed. She was breathing the deep, regular breaths of someone fast asleep.
Megan knew that when he woke up, Nick was going to be really thirsty so she got a glass of water for him and put it on the bedside table where he would find it when he woke up.
Several hours later, just as Megan was thinking it was about time to start getting ready for bed, she heard Nick stirring in the bedroom. She heard him stumble sleepily to the bathroom and a few seconds later start swearing. Megan smirked knowing that Nick had just been reminded about his current body's inability to pee standing up. That thought made her wonder what it would be like to pee standing up herself. She looked at the clock and realized that it had been 12 hours since she had used the medallion so, if the note was correct, she should be able to use it again. She thought it would be nice get these ridiculously large breasts off of her chest at the very least.
Megan waited until a few minutes after she heard Nick get back into bed before she crept silently into the bedroom. The medallion was right where she'd left it on Nick's dresser. She grabbed it and a pair of Nick's underwear from the top drawer and then made her way to the bathroom. She looked at herself in the mirror and smiled when she thought about what she was about to do. Megan quickly slipped the chain of the medallion over her neck and then pressed Nick's underwear to it. The tingle immediately told her it was working.
Megan watching as her medallion enlarged breast quickly diminished. Soon she could see her feet again and then her groin came into view and what she saw there was truly fascinating: where she was used to seeing just a patch of pubic hair and a slit she now had a small penis and testicles that were both quickly growing to their full size. Soon Megan's reflection looked exactly like Nick's had until very recently. She smiled at her new reflection as she put the medallion in her jewelry box then made her way over to the toilet. Then, for the first time in her life, Megan peed standing up. She was thrilled by the new experience.
After brushing her teeth, Megan made her way back to the bedroom, nearly tripping over the dildo still suction cupped to the floor, and climbed into bed naked as her boyfriend was in her body.
