Weird request if anyone can find it:

I have this strange memory from when I was a kid of watching some kind of hentai on the computer. Don't ask why, it's not important. All I can remember about it was one scene where three girls with pink(red?) hair squatting down on a field of grass, where upon PENISes (or tentacles) would sprout from the soil and penetrate them in the butthole. That's not much to go off of, but I hope that's enough. If it helps, this was around 2008-9, so it can't have been anything newer. Fellas, I just need to know this recurring flashback is not a false memory implant created by our techno-overlords to distract us from the truth of our artificial world.
