Fucking brilliant. The thought had crossed my mind as well.  I know that the owner made or designed many of the features at the club, but the swing HAD to be a custom job.  If you're building a playground for adults, you want everything sturdy so it doesn't break in the throes of passion and cause injury.  But at what point do you look at a 'marital aid' and not say to yourself "Fuck it, I'll just toss a sleeve of oreos into a tub of mayo and have the fatties gorge themselves to orgasm instead."
