Sorry for the delay, i was away for a while. And for your question, yes and no. The girl in there is both in a hentai episode and a hentai game. She's from the "Hawaii vacation" game iirc. From Meet & Fuck. And another one, called Beach with Erin or something like this. My memory is kinda fuzzy right now, but you should be able to find more about her with those informations.
