College student Mia feels completely inexperienced in romance until a daring impulse drives her to seek guidance from Ashton, her best friend's handsome older brother. Knowing he is strictly forbidden territory, she proposes an undercover arrangement where he teaches her physical intimacy under rigid boundaries: zero kissing, zero emotional attachment, and absolute secrecy.
What starts as clinical bedroom practice quickly spirals into overwhelming lust each time their private sessions turn intense. As Ashton drops his detached facade, Mia must decide whether confessing her true feelings is worth fracturing a lifelong friendship and losing him entirely.
