Just in time for #MilfMonday, Doc Johnson and Vicky Vette's VNA Girls Network have released MILF in a Box, a collection of signature UR3 strokers featuring star MILFs, Julia Ann, Francesca Le and Charlee Chase.

Each UR3 Pocket Pussy includes a discreet, travel-friendly, reusable and washable box so fans can take their MILF in a Box anywhere they please.

"We spent a lot of time developing MILF in A Box, particularly the discreet, travel-friendly box," Doc Johnson's COO Chad Braverman said. "We anticipate the collection will be a smash hit with fans. Unlike some other masturbators on the market, the new MILF in a Box products are easy to pack and take with you on the road."

To celebrate the launch, each of the girls will be giving away two of their debut MILF in a Box realistic vaginas to their Twitter fans.

To enter the contest, fans must follow @TheOriginalDoc, @TheRealJuliaAnn, @Charlee_Chase and @FrancescaLexxx on Twitter, and by March 10 must tweet out "the best thing about having a MILF's vagina in a box," contest organizers said.

To qualify, the tweet must include @TheOriginalDoc and at least one of the girls.

Winners will be chosen and announced on March 11.

Doc Johnson Enterprise:
Doc Johnson was born in 1976 when Ron Braverman purchased a very small company that sold adult toys along with gag novelties and rubber fishing items. When he realized that adult toys had a huge demographic without any real central supplier, he renamed the company Doc Johnson and worked towards becoming America's most imminent producer of adult products. Since then, the Doc Johnson brand has grown and evolved. We started with a handful of employees, and now have a team of over 500 people in our factory in North Hollywood, California. The adult novelty industry has grown and evolved, but one theme that has remained constant at Doc Johnson is our strong commitment to American manufacturing. Today, we are the largest adult toy manufacturing company in the world with a facility that has six buildings that cater to every department from conception to shipping - and not only do we produce the majority of our products in America, but we also strive to create the most high-quality, innovative, and body friendly products on the market.
