She's using superglue on her tits to ensure the clamps stay in place. Nothing wrong with that. If it's both scary and exciting, it's most likely a total thrill. Plus I'm pretty sure she had the superglue disolver nearby otherwise she would have major visible scars in her other videos.
I'll bet she really regretted the super glue. Those clover clamps are pretty intense without gluing them on. Like the way she tugged on them while bouncing on the fat dildo. The sensation is incredible! I would really love to know this adorable little slut's name.
