If you're looking for a happy ending, 112 massage parlors in Washington State allegedly offer erotic services.

The website EroticMP.com promises to help you "stop wasting time and money on services you don't want." In fact, customer reviews provide fairly specific details on exactly what you would get - for the right price.

A man with the username "absolutelydiscrete" wrote a scathing review of Far East Healthcare Spa in Lynwood, Wash. The man described the sex act he received from a 30-something Chinese woman as "poor," writing that he "told them the service sucked and walked out the door." He goes on to describe his masseuse as "half ugly." But, lucky for him he could charge the $60 alleged act to his VISA.

Another user wasn't so critical of the parlor, calling his service "the best" and recommending it to other users. "Nothing but class," he wrote. "Treat them with respect and you will leave there feeling way more relaxed."

Information provided by users on the site is extremely specific. Reviews typically indicate the provider's age, height, build (slender to chubby) and note whether she had breast implants. There is even a field indicating if the business has parking space for an 18-wheeler.

While the website would be a useful tool for people looking to engage in prostitution, it could be a more useful tool for police.

"I wouldn't say that every massage parlor is a front for prostitution but some are," said Sergeant Rodney Chinnick with the King County Sheriff's Office. "Certainly if they become aware of information through the Internet or otherwise, that there were massage parlors operating in their city limits that were actually fronts for prostitution, yes they'd definitely be interested in investigating."

While King County would be "interested" in investigating the parlors listed on the site, it may not be possible. Their Vice Unit, which would typically handle such operations, was cut due to budgetary reasons, said Chinnick.

"The budget has forced us to carefully evaluate our priorities," he said. "Our main priority is being in a position to respond to 911 calls." He added that if human sex trafficking was suspected in one of the parlors, it would be a higher priority than investigating prostitution.

A Seattle Police Department spokesman said he wasn't aware of the website, or if they were investigating any of the 17 parlors in the city reviewed by the site's users.

Some of those parlors, however, appear to be legitimate businesses.

"Touch of Class Spa" in Seattle is featured on the site, but a user said he does not believe any illegal activity takes place there.

"If you want a relaxing massage, this is an excellent choice," he wrote. "This is a legitimate place, don't try to solicit for any dirty play."

But comments indicate that many of the parlors listed on the site in cities like Tukwila, Federal Way, Bellevue, Everett, Kent and Renton are indeed fronts for illegal activity. One of the most "active" parlors in the state appears to be in SeaTac.

Nature's Gate Healing Center has 49 reviews and the most recent post is just days old. One user recommended that another solicit service from a woman named "Rose" during an extended layover at SeaTac airport.

"She's beautiful with a great bod," he writes. "Does offer amazing FS," which indicates that the woman would engage in intercourse.

The same parlor is also listed on BackPage.com, a Seattle classified service that Mayor Mike McGinn has openly opposed. Some believe the website's personal ads deal in sex trafficking.

Calls and emails to EroticMP.com went unanswered.
