OMFG, I used to fuck the same kind of vacuum, it gave unsurpassed head sucking my Irish mushroom dickhead to never-before-or-since-seen proportions, thrashing it all around in there, flapping it against stuff totally turbulent environment if I chose a particular angle. Else it just relentlessly sucked and I could ease it in and a little back out my shaft was vibrating at super high frequency as the air rushed by my skin. That fucker swallowed every gallon of cum that it pulled from my pisshole daily!!! Plus, I had a wet or dry shop vac with a 3 or 4" dia hose that itself flopped around beating my dickhead around slower and longer strokes. It guzzled my piss and cum whenever I wanted. Sure was noisy lol
Somehow I want to lay on my back under you while you're fucking that vacuum, maybe just have the hose near my asshole and you fuck it - whichever hole you want and piss in there for me
LUVED IT !!!
