Its kind of weird to see cover art like that on a Famicom game. It may come as a shock, but this may not even have been licensed by Nintendo (gasp).It came out in 1990 and was released by a company called Super Pig.
Reading through the FAQ it seems that despite the title and provocative cover art, this game has nothing to do with sex. Its basically just a Space Invaders clone. I guess for marketing purposes they decided the best way to sell that was to spice up the name.
That doesn't seem to have worked though since I don't think many copies of this game exist, I've never seen it before. Ironically that makes it one of the harder to find Famicom games out there and thus the focus of a lot of attention among Famicom collectors. Out of more than 33,000 Famicom items up for auction right now, this one is near the top on Yahoo Auctions "most paid attention to" listing, and is the number one Disk System game. Its currently got a bid of 3433 Yen with 3 days left, I'm curious how much it will go for. I'm not a disk system guy, or a sexy guy, so I'll pass, but thought it was kind of interesting nonetheless.
Postscript: The auction for this ended at 30,501 Yen, about 300$ US!
