Looking for a older cinemax afterdark, showtime, or hbo movies from the 80s to 90s. One is about a weathly to-do couple and the husbands nephew, who is about 16 years old, comes to stay and the wife ends up seducing the nephew and taking his virginity on the couch in the library/study. Might take place in London? The next movie has a sex scene by a large water fountain and the persons engaging in the sex are dressed up in victorian attire and are attending an victorian/masquerade party. I have been trying to find the names of these movies and have to such luck... They are bold in color and I'm pretty sure they are from the 80s if not 70s. Thanks!
