Do you mean mainstream porn or wam porn? If you're interested in the mainstream stuff http://sssh.com has videos like that. It's a site marketed to women so they include more foreplay and actual story lines.
There are a LOT of adult movies on YouTube of the less than hardcore variety. Since my weakness is for Asian ladies I search on the Japanese terms for "erotic" and "fuck" and filter the results by Duration = Long (>20 minutes). That search looks like this: https://www.youtube.com/results?filters=long&search_query=%E3%82%A8%E3%83%AD%E3%83%95%E3%82%A1%E3%83%83%E3%82%AF Click to one that's feature length (say an hour and twenty minutes) and there will be plenty more in the "Recommended" column to the right of the player. Of course YouTube is always taking these down but not fast enough to stem the tide Just as an example (which will surely disappear soon) that search brought up this amusing 1975 hippie love film called "Pickup" https://www.youtube.com/watch?v=mlBFQqme40w (IMDB listing here). Not quite what I was looking for, lol, but the Recommended column is an endless rabbit hole of not-too-graphic smut. When I want to try different search terms, Google Translate is my friend, both English to Japanese and Japanese to English.
Love you, too
I figured WAM was a given, but I'm also looking for non-WAM.
