Bellaire laughed as Stan walked in fast circles trying his best to see what she had helped him change into. Little did she know, that her changes were far from over. She felt sudden pressure in her groin area. She started to make humping motions involuntarily with her hips, as the tip of a massive black cock sprouted from between her legs, it's length increasing by the moment. It was soon followed by the feeling of two softball-sized testicles in a dark, leathery sack slapping between her still-womanly legs. Bellaire continued to buck her hips until her huge black penis completed it's growth as she threw her head of black hair back from the sheer pleasure she was feeling from the growth of her new beastial equipment. She took the beastly member in her feminine hands and swung it from side to side, feeling its 2-foot length slap against her legs.
