I'm not aware of many specific stories with exactly that title. But in general, in the realm of gay literature, there are stories that explore different power dynamics and relationships between older and younger gay men. These often focus on the emotional journey, acceptance, and the unique bond that forms, rather than a particular act. For instance, the works of some emerging gay authors who are trying to break taboos and show the real and complex nature of gay relationships.
There are some works that may contain elements of this. However, it's not easy to find directly titled stories like that. Some gay short story collections might have stories that deal with the dynamic between an older and a younger gay man, which could potentially include some aspects of what you're asking about, but it's more about the relationship and emotional connection rather than just a'suck' story in a vulgar sense.
