Marcus and Claire (Alex Jones and Melody Marks) are a down-on-their-luck couple, having hit a string of bad luck recently which has left them without a place to live. Luckily, their ex-college professor, Frank (Ken Feels), has agreed to let them stay with him at his home. Marcus and Claire feel embarrassed to have to ask this of Frank, but at the same time, it's not like they have a choice. They assure him that they'll be back on their feet in no time. Frank, however, is welcoming and generous, assuring them that this is just a speed bump on the road of life. And besides, he's happy to help his ex-students. insisting that 'mi casa es su casa'. But as the days go by, the couple soon finds that Frank's open-door policy is a bit more intense than they initially expected. Franks seems to always walk in on them when they're getting frisky, and although he acts casual about what he sees, there's a distinct sense that he's almost doing it on purpose. The more it happens, however, the more normal it begins to feel, to the point where Marcus and Claire are totally unfazed by the intrusions and interruptions. But then one day, things get dialed up a notch when Frank walks in on Marcus and Claire having sex in the living room. Frank insists that they continue fucking, even though he remains in the room. Marcus and Claire don't hesitate, continuing to fuck as Frank watches TV next to them. Eventually, however, Frank can't help but ask if he can join. The couple are a bit taken aback, but ultimately resolve to reward their host for his sublime hospitality with a threesome.
