Sweet Little Unforgettable Thing (слэш)

Peter, upon his acceptance to MIT, turns to online sex work in order to make tuition, selling an explicit Snapchat - among other things. One night when Tony is mildly drunk and feeling lonely after his split with Pepper, he purchases the Snapchat, unaware that it's Peter's. But instead of confronting the boy, Tony remains silent on the subject, consuming Peter's content voraciously and spoiling the boy like crazy, while he remains completely unawares that it's really his mentor/crush who has been spending seemingly all his cash on him.
