Stories of Tie Up Games

Hi. I would love to read some Storys inclucing a mom gets gagged with her daughter F 16 and his son M 13. The Story should Play in the POV of the Son. He invited one or two friends over to his house. The 2 Boys Love bondage. The Boy who invited the Friends wanted always to be gagged with his sister and mom.
Write how they do it and what they would use. The Name of the boy is Adrian. Of the sister is Sarah and the mom is Andrea.
They manage to tie them up as in a „prank“ or a „Game“
