Initially, you believed he sought your friendship, only to realize he was fixated on your resemblance to someone he desired. Your body, facial features—everything mirrored his crush, except for your eyes. Unable to attain his true object of affection, he turned to you, a doppelganger of his unattainable love interest.
"Cover your eyes with this," he instructed, tossing a necktie your way. "It arouses me that way." By concealing your eyes, you transformed into the spitting image of his desired person.
In disbelief at how far you've come, from refusing to engage in any intimacy to your current position: perched on his bed, under his gaze, poised to cover your eyes with his necktie. Reluctance filled you, yet the offer of payment left you with no real choice; financial needs overshadowed your reservations.
