I'm looking for a scene from the early to mid 90's. The scene has Alex Jordan in it, but she does not have sex in it. She acts more of like an evil Mistress. As I recall she is leading a woman and two men on a tour where they encounter some sort of glass tube.
The other female goes inside and Alex mentions something about a pneumatic dildo pump. Then out from the floor it comes. The gal gets fucked silly with it and then is finished off by the two guys. I'm thinking I saw it in a compilation video of fetish scenes. Don't know if that is enough to jog someones memory, but thank you in advance.
