I'd say it's about 50/50. A lot of models get on cam multiple times a day, every day and only cum when they get the tips they are asking for. Folks like that have TONS of videos posted, many of which don't have the payoff. Then there are the folks that only cum in private or as part of a ticket show. And the people that pay for that tend not to be the ones sharing with the rest of us lol
Whatever is posted here, cum or no cum, are mostly requests that people wanted...probably with the hope there would be the ultimate payoff but at least knowing that they included things they wanted to see (bulge, dick, balls, etc).
All things - what is a crazy ticket show??
