Most of scenes from book one in Four elements trainer. Both the love and slave route have great scenes. It was the first pron game i played so probably a little nostalgic bias
There are a few porn stars in real porn movies that I'm very impressed with and admire their pussy, I go back to their scenes over and over again. Does that count?
The older one with the brunette woman leaning over the table taking it from behind before she's a good girl and swallows his load... it's old enough that it legit feels like they were in an office.
