Hey everyone, this might be a long shot. But does anyone know of a vintage porn movie from 70s-80s about (something along the lines of) a woman who somehow stumbles into the wrong apartment. The apartment is home to a lesbian couple. She's straight, but is seduced by them. Does anyone know of this movie or a similar one?
Also if anyone has a story like this as well. Thank you! I could have sworn I watched this!
