Nothing happens and I use more of my mom's clothes

Nothing happens, no matter how strange it is. I expected to hear my mom scream or something, but nothing happened. I thought it was weird, but I decide to use more of my mom's clothes. I start sorting through the laundry basket and find her panties. They were black in color and they smelled really bad! But despite this, I held my breath and gradually began to pull them on my legs. As soon as they were in their place, I felt a familiar shiver in the area of my groin and my ass. I went to the mirror and looked into it. I could see the bulge on her panties gradually begin to decrease, and the pressure to ease. After a few seconds, the panties already looked about the same as they looked on women. But the trembling didn't stop. It gradually began to rise to my stomach. Apparently, something was changing inside me. And it was... Pretty painful. But it didn't last very long. When the shaking stopped, I turned around and looked at myself. The lower half of my body completely matched my mother's body. I gradually lowered my mom's panties down my legs and saw that now instead of my penis, as expected, there was my mom's vagina! She was clean-shaven and well-groomed, despite her age and the fact that her husband had long since disappeared.
