I am guessing that the company is listed on the stock exchange as 'Girls with big Bazonkas corp.' but has a rather more mudane corporate title. I suggest that when you write your résumé you use the plain name.

It's also worth pointing out that there are varying degrees of pornography. Playboy, for example, is unlikely to spark much controversy. An on-line publication featuring borderline illegal hardcore is less likely to get by on a CV.
At the end of the day any job pays the bills and you may end up with some valuable experience that you can use in other jobs further down the line.
