He isn't even sure why, but he has the impulse to put on the necklace. Before he can think about it, he is closing the clasp behind his neck. Just as the circle was completed, he felt a very strange wave of cold prickly energy, then a surge of warmth, a feeling of calm, and a feeling of surrender. His thoughts started to melt together and he found himself feeling female -- whatever that meant! Suddenly, he realized that he was being emasculated. The physical emasculation had already taken place down below -- and he was suddenly aware of "feeling" his ovaries nestled in his abdomen, and his uterus and vagina...softening and getting wet at the moment. But this was different - this was a mental emasculation. No! Feminization! He/she realized that being a girl wasn't the absence of testicles or anything so simple -- it was another thing entirely. He was becoming FEMALE in his thoughts. At the same time, a feeling of acceptance swept through him. Hard to describe, though. It was definitely not a feeling from him - it was a feeling being forced into his brain. But he could no longer resist. His mental resistance totally collapsed, and he realized he was a girl - inside and out. His manhood suddenly felt like a lifetime ago, although in reality it had only been minutes. But, with his manhood, his resistance had left him. He was totally female and couldn't even conjure the feeling of anger or frustration. Acceptance flooded his thoughts. Forced-acceptance, but acceptance nonetheless.
He looked down at his chest and marveled at how suddenly his breasts had developed and yet how unnaturally comfortable he already was with them. His focus shifted further down. He saw the utter flatness - the unmistakable small mound of womanhood safely concealed under his binkin bottom. He could absolutely feel the unmistakable feeling of flatness -- of womanhood -- of his clitoris, suddenly his vagina and uterus and ovaries. Just as he thought about how strange, and yet acceptable, it was to have ovaries, it was as if he felt a little "pop!". He *knew* what had just happened. He had ovulated! He was going to have a period in a few days.
The thought of a period briefly terrified him -- but was immediately smothered by that forced acceptance.
He started to cry. He wasn't even sure why. But he knew he was totally female -- and he was convinced that was going to be his condition henceforth ...for the rest of his life.
Again, his mind fought back -- thinking of girls he wanted to penetrate - the feeling of loss that he could never do so again. But then the feeling that he was so lucky and happy to be this girl.
