If you have three minutes
Mona's Obsession gives you 3:13 before the paywall, more than any series bar one, and its premise needs no explaining: a woman who cannot stand her stepbrother and cannot keep away from him either. Private Lessons gives you 3:11 with Mia Malkova as a yoga instructor whose one-to-one sessions get personal. Under the Boss, at 2:56, is the office one: a new temp, a boss who fixates on her and an assistant who is having none of it.
If you want the newest
Forgive Me, Father and My Wife Hired My Nurse both arrived on 2 October, a day after My Step-Sister's Bachelorette Party!. New series have been getting tighter, with free episodes close to a minute each, so these three give you between 2:03 and 2:24 to make up your mind.
If you came for a performer
Riley Reid has three series and Mia Malkova one. Riley's openings are among the shortest on the platform, under two minutes for her dormitory and wife's-best-friend titles, but they are built around her rather than a plot, which is what most people opening them want. Mia's is the opposite case, one of the longest openings anywhere.
If you like a long story
YES MA'AM runs twenty episodes and Mona's Worst Enemy fifteen, which gives their stories time to change direction more than once. Both give you more than two minutes free, 2:15 and 2:44. The price of the length is in tokens: 216 and 156 to reach the end.
