Gunma is in the news because the prefecture's mascot won the Yurukyara Grand Prix. Hearing that the wife's crotch is loose, he picks up a couple in front of Takasaki Station, and just like the mega-sized pasta, a local B-class gourmet food, her crotch also has a mega-sized orgasm. The next day, he goes on an adult field trip to Tomioka, home to a silk mill that has recently been registered as a World Heritage Site, with the wife, who loves sperm instead of silk. The two are both masochists, and they spin semen into his mouth with a tearful deep throat. Also included is a special episode of the amazing squirting wife who ends up incontinent during sex!
