Have you found that there's simply not enough "tactile feedback" in your porn games? Japanese adult game Huge Breast Fantasy aims to remedy that, coming bundled with two giant squeezable breasts and a G-cup bra.
Yeah. I'm kind of finding myself at a loss for words, here. At first, I was wondering if perhaps the pair of squishable "oppai balls" (oppai, of course, being the Japanese word for "titties") were included as an optional control method. You know - plug them in to your computer via USB, squeeze them, watch the in-game girl react to your lascivious groping.
But no, as near as I can tell, the oppai balls have nothing to do with the actual game. They aren't part of the interface, they're just part of a special bundle for Huge Breast Fantasy for those who feel that the simulated touch of synthetic human flesh is worth ¥11,000 (US$123). Even more perplexing is the fact that the included G-cup bra seems to suggest that these are meant to be worn. Presumably by the player themselves.
I guess that's an entirely different kind of "Huge Breast Fantasy," to be fair.
I bet this game was secretly made by Team Ninja.
