Most of the time, I only look at porn for inspiration, and I don't coom during that time. I also read a lot of porn on AO3, or listen to gonewildaudio. But for masturbation, I just close my eyes, and imagine a sexy scenario.
For my last fap, i imagined a scenario where the token girl, in my otherwise all-boy friend group, got peer pressured into being our group's cumdump. She lost a penalty game badly, and doubled-down too many times. Although it would have been within our rights, we didn't just gang-bang her there. Instead, we organized allotted time-slots on a literal calendar, specifying which boy she was obliged to see, on what day, and what she was obliged to do with him. We started slow, so that she could get acclimated. Boiling the frog slowly. Week one, first base only. Week two and three, second base only, etc, etc, etc. And that escalated over the months. Before three months were over, we had gotten to the point where we scrapped the calendar, as she had become a free-use cum dump for the group; anything we wanted, any time, anywhere.
