Possibly her fist "Nip Slip" on her new VDay set. Posting the set in a minute on the main thread so go take a look over there.
Just my thoughts on it.
-It's very subtle so might not even be a nip slip.
-It's definitely not a pastie or not a part of her Ribbon Outfit.
-In my opinion, she doesn't let a real "Nip Slip" slide during her editing time, so I think this is her "Testing the Waters". I know for a fact her previous sets that she blurred heavily did NOT do well.
-If she did actually let this "Nip Slip" slide on purpose it's a good sign for future sets.
-Discuss away my fellow perverts
