Yes! It seems all of a sudden a new sub-sub-genre. I think I saw two different vids with the same setup just last few days.
In 1Pondo-092415-159 - Aoi Shirosaki, the film was set up as a documentary style with her arriving at an apartment/office. An assistant offers her a selection of drinks or snacks and a document. She scanned the doc and have a conversation with an off-camera male. Judging from her tone and manners, I speculate the conversation was a discussion of making an uncensored AV. And she was just agreeing to the general terms and condition of the job when a totally nude man quietly emerge from behind the sofa and climb onto the sofa, and she only noticed his presence when his weight tipped the cushion she was sitting on. She could barely register his appearance out of nowhere when he already manhandled her body to pull her skirt up and panty down and insert his nearly-fully erect penis into her vagina. It was so quick that she had barely finished the first yell of surprise to a loud moan of having something forced into her orifice. For the first half minute or so of fucking, I think she was so befuddled by the situation that it must feel like suddenly having some one pinching your little toe very hard, in the middle of a business meeting! it probably did not register as sex at first.
I was watching it when my partner was next to me playing some farm game on her phone. Normally she would keep playing the game until either she finish the "chores" or the on-screen sex gets really hot (which for the typical AV this might well be 45 minutes). But not this time, she got in the mood quickly (close-up shot of a big fat cock pistoning a shaved pussy without mosaic can do it for her) soon we were having sex. After that I fell asleep and she finished watching the video. The next morning she made it a point to tell me how the actress really had a good time (wasn't faking the orgasms).
So: four thumbs up!
