Piper and Michael Collins have it all. They’re in love, both have successful jobs, live in a nice neighborhood, and have a great sex life—that is, up until recently. Over the past six months everything has started to drag. Even though they’ve led an “extracurricular” lifestyle for a long time, things have gotten boring.It’s up to Piper to liven her marriage up, which she does with a little encouragement from her pal Caroline at their weekly STD happy hours. She jumps in without pause and sparks between she and Michael fly. First with hot selfies, office sex, and later with some much needed risk-taking. From there, Piper and Michael make a Top Ten Sex List and start ticking off their wildest fantasies. Piper is fearless, but when they both arrive at Michael's number ten, is Piper really ready?
