Just as you felt like you were about to be consumed by flames, the heat and fire was gone. You open your eyes and see that you were back home in your apartment.
Hope that it was just a weird dream or hallucination were quickly dashed by the feeling of metal around your neck. You grab at at the collar, trying to take it off, but there was no latch or anything. The whole thing seemed like a solid ring with spikes sticking out. You would need a blow torch or haxsaw to remove it.
You rush to the bathroom to look at the collar, but are distracted by your hair, it had changed color. It now seemed to be raven black. Unable to believe what was happening, you check for other changes.
You remove your shirt and discover muscles like you never had before. Your whole body seemed to have become nearly perfectly defined. You marvelled at your well defined pecs and six pack abs. You flex in the mirror admiring your larger body. You had always tried working out, but you never had enough time to make a real difference. Now you look like a model.
Further investigation of your body found your penis was longer than it was when you woke up this morning. It appeared to be at least 8 inches erect and erect it seems to want to stay. Despite the impossible events of the day, you feel so horny and you just want to give your new body a try out.
