FYI, the slurp ramp that was in Steamworks Seattle has been removed and replaced with a more open play area with a large bed and a sling. Make of that what you will.
There's always been plenty of cock sucking at SW, after all it is the gay handshake and an almost required prelude to fucking. In eCommerce terms, sucking a man's dick is a "conversion opportunity" - you engage with sucking and close the deal by fucking. There's plenty of fucking going on from the smashing and moaning noises that are clearly audible as you walk around. And when I've been fucked in the public spaces guys seem to want to either fuck me, or catch some of my top's dick.
