What are the sexiest moments in mainstream gaming? By mainstream gaming I mean events that happened in game or during cutscenes of commercially released and marketed games on console/ PC. Mods, porn parodies, hentai games, fan art and creations, and dating sims don't count.

The absolute sexiest moment is obvious:

But what are other possible runner ups?

The GOW games all had steamy sex minigames. From memory I think GOW III and Ghost of Sparta had the best ones.

GTA San Andreas had Hot Coffee. Originally Rockstar claimed it was a mod but the data was on the disc so they lied.

Who could forget the first time Samus took her clothes off (spoilers)

Who could forget the first time Mario took his clothes off?

WWE Smackdown used to have Bra and Panties matches

What else? Remember to keep it Safe For Work!

Fear effect 2 the elevator lesbian scene and also parasite eve 2 the shower scene.

It's difficult for me to view pixels and polygons as sexy so, I can't think of anything. Maybe some of the girls in Night Trap?

Not really much to go on, but PN 3 had some good animation.

I don't remember the scenes exactly, but I'm pretty sure Catherine had some nice ones.

Since someone mentioned PN3, we can't go on here without mentioning its younger cousin, Haydee:

But Haydee is probably the opposite of mainstream gaming, so it probably doesn't qualify for this thread. Can't really think of anything mainstream at the moment...maybe the sex scenes in Wolfenstein: The New Order? The fanservice in Final Fantasy XIV? Getting into some non-consensual action with a muscular russian woman in Alpha Protocol? Pyramid Head raping some mannequins in front of James on Silent Hill 2? Yea, lemme just stop here...

Also OP, can't post sexy Raiden (I totally agree with your choice, good lad) without this extra add to that whole sequence:

The scene in FFXIII where Snow is shirtless in bandages : 

The introduction of DmC: Devil May Cry:

Well if you read the OP....
