Karma Rx is visiting her sister for the first time in a year and is eager to meet her husband, Markus Dupree. What becomes abundantly clear to Karma Rx, though, is that Markus Dupree – seemingly prim and proper – is wildly attracted to her, a fact crystalized when she catches him masturbating to sneaky pictures he snapped of her ass. It turns out that Karma Rx likes what she sees in her new brother-in-law, and despite having to go to extreme lengths to avoid getting caught by her hawkish, conservative sister, Karma Rx eagerly gives up her ass to make that oh-so-important perfect first impression.
