Lip Service makes a case for the "less is more" approach to adult videos; namely making due with a slim but serviceable story to concentrate on production values and hot sex -- especially if viewers crave more of Jenna, who dominates three out of six scenes with her drop dead loops.

As a 900-line "call" girl, Jenna reaches out to touch Brad Armstrong in a fantasy opener that relies too heavily on post-FX, but it sets the stage for her to audibly witness his murder (by underworld baddies St. Croix and Davis.)

The ensuing "catch me if you can" game is played out fairly effectively. A three-way with Davis and St. Croix in a dark service elevator captures more mood than heat, but Jenna reaches her literal "high point" while engaged in a hot oral session with Vince Voyeur, sucking his dick on a very public fire escape!
