Jessica nailed down Ruby's puffy tits to a wooden beam with some thick and long decorative pearl pins. But after that a little happy accident happened. When Jessica ordered her to stand up she just fell down on her tits lol and all the beautiful pins got broken and they needed to get pulled out. Since Ruby ruined her beautifully decorated tits she deserved a punishment. After pulling out the broken pins from her tits Jessica nailed her nipples down with some real nails and then she whipped her while her tits were fixed to the wooden beam. In the end Ruby was so knocked out that she collapsed but Jessica did not let her relax, she grabbed a vibe and pushed her to have some pleasure and then Jessica herself also had a huge orgasm. I have added some behind the scenes moments to the end of the movie, you have to see how Ruby fell down on her tits. After we made sure that she was ok, we hardly could stop laughing.
