That's a scene in Grand Theft Auto V where you can go to a strip club, sit down, and watch a digital person wave her parts at you for as long as you want. The point isn't whether or not I jerked off to a digital stripper in Grand Theft Auto; no one's on trial here and this is a judgment-free zone. The point is this also happens in Metal Gear Solid V.
If you hang out in your helicopter for long enough with the character Quiet, she'll start waving her butt and boobs in your face. The games I've listed, at least, have the dignity to pick a girl for you -- the franchises Mass Effect, Dragon Age, and The Witcher all have "romance" side quests that are basically mini-games that reward you with whatever genre of light porn you want: "Do you wanna whack it to blue alien butt, elf tits, or a naked brunette on a unicorn? Your call," says the game, to you, the player.
Again, there's nothing inherently wrong with this. I have no problem with you being porn, video games. You do you. All that I ask is that if you are porn, please let me know so I can hide you when my mom comes over.
