This is part 1 of Halloween Tales
Jacquelyn is tipsy after a Halloween party and is getting ready to go to bed when someone handgags her from behind and takes her away to his lair. She awakens stripped to her bra and panties and bound to a table. Scott is excited to have a new volunteer for his experiment. Her screams are interrupted by a tight cleave gag and she can only mmph and struggle against her tight binds. She tries to communicate with this eccentric scientist, and he is annoyed by her constant harping. Thinking she may have something important to say, he agrees to take the gag off, but her pleas and promises make him quickly regag her. How dare she get in the way of scientific progress?
