The Glass Coffin (2016)

The Glass Coffin (2016) is a horror film from Spain that follows a young woman getting ready for a magical evening. She is dressed up and gets picked up in a limo, but suddenly her phone doesn't work and she can't open any of the doors to get out. A voice tells her to do what they say or things will get worse. Paola Bontempi stars as the trapped girl who unzips her dress at one point to reveal her black bra. She is made by the voice to five head...to her own high heel. Kinky! Finally, we see her buns when someone comes in and takes off her panties. Thank goodness for the "glass" so we can see everything!
