I was initially hesitant about messy anal and dirty ATM, but it turns out it's a huge turn on for both my girlfriend and me, to the point that we now only have sex when she is full. My cock is usually absolutely covered with her shit and she loves it. Dirty ATM is a core part of her submission.
Not me, imI hate the smell. It’s an instant turnoff if I smell shit. And there’s no extra joy if there ‘s shit on my cock when she sucks it. It ‘s feels just as good while it’s clean.
