REID CALLAHAN has spent his life doing exactly as he’s told, living up to the image crafted by his father, but he’s desperate to find something more. When he signs up for a dating app, the last thing he expects is to form a connection with a man who’s fourteen years older than him. And he definitely doesn’t expect that man to end up being one of his professors for the semester. EMILIANO CERVANTES has been craving connection. At thirty-seven, he’s been the perpetual bachelor, never interested in more than a few dates and a casual relationship. At least, not until he’s captivated by a mysterious man on a dating app. Reid quickly becomes everything Emiliano didn’t know he wanted. Only for Emiliano to realize he’s someone he can’t have. Learn Your Limits is an MM romance with the following tropes: age gap, professor x student, secret relationship, lots of texting, "teach me," and bi MMCs.
