Â He had been collecting female clothing for a few months now. Sissy Gabby was a cute little sissy boy in yellow panties and a yellow nightie. When I spoke to her I was immediately taken by that soft voice. I knew Mommy had to push her further. She wanted so badly to be Mommyâ€™s sweet sissyÂ boy who would be taught in time to be a big girl. Before that, she was to be trained as a cuckold. Training started last night.
