Probably … damn, so many … but probably eating a man’s ass.
Like the others have said, I love an orgy during which everyone is in the mix, not having any idea with whom they are having sex. I’m a voyeur and love to watch but I’m also an exhibitionist who loves to put on a show. Men standing around jerking off watching me have sex. The eroticism of slithering my arm upper buddies ass. The intimacy of unloading my sperm up a mans ass. My arms and legs enveloped around him as we passionately kiss and make out. This silent whispers of what we are feeling and doing and want to do with each other. All that is a huge turn on.
But when a man pulls open his ass crack and proudly shows off his hole, and let me get very personal and intimate by sticking my tongue up his hole, that sends shivers through my balls and up my spine and very quickly helps me build up to the point of no return.
