I restrained this schoolgirl and placed a sex toy inside her panties

After this schoolgirl returned from school, I sneaked her into my bedroom and tied her hands. I then spanked her pussy multiple times. After I spanked her pussy, I placed a vibrating sex toy inside her panties. While the vibrating sex toy was inside her panties, she had multiple shaking orgasms. She begged me to remove the vibrating sex toy, but I refused.
