I've been an anon cumdump plenty of times at mid town NYC hotel rooms and airbnbs . While I love the experience of being alone in the room and have guys pound my ass one after the other as I sniff away on poppers, being blindfolded the entire time, an interesting addition to the experience can be sometimes if I find a voyeur top to oversee the whole thing.
It's hot, adds another person looking after my safety , I don't need to take off the blindfold for ANYTHING, and if the voyeur is someone who enjoys facilitating more and more guys coming in, sometimes they start calling more guys just to see me get fucked by more meaty monsters. It's not something that always works out in terms of timings and logistics, but when it does, it's fucking HOT.
