Porn scenes with matter of fact sex

I'm looking for scenes where sex is not the main focus, it happens, but the participants are talking about something else, they are not pretending enjoying it immensely, there are no fake moans, etc.

Note that I'm not interested in anything scripted, the scenes should be 100% real, not some reality porn where they pretend it's real, but it's not (fake castings, etc.). Also, I'm not looking for porn blooper compilations and such. I'm interested in scenes where sex happens, but it's mainly a side activity while the actors are chatting normally, not acting.

Here's an example of what I'm thinking of. I mean the first scene of this video where one of Rocco's pals has sex with a girl, but it's some between scenes shot, so there is no pretending and they are chatting about something else: the girl is explaining why she does not enjoy sex in porn scenes:

Do you know similar scenes which fit the above criteria?
 
Here's an other such video. It's a bangbus like situation, but there is no pretending of finding a girl on the street, etc.. Instead Gianna Michaels and a guy goes with a bus and the only instruction is they must have sex in public. And they do, but they are chatting during the act, making jokes, etc. even walking naked in a store. At the end Gianna swallows naturally like it's part of the job. She even says it.

Pretty girl does an interview and then does the gloryhole, swallowing each drop from multiple guys one after the other:

Can you identify the actress? Here they call her Starla, but I'm looking for other names to find more videos of her.
