While she's not for everyone, Nat at myasaingfe has been the only one who has been able to aggressively DT to the hilt with me. When she's in the right mood, she will facefuck herself and ram that last inch like nobody's business.
Nikki from AL was able to get there, but with more caution on the last cm or 2. Haven't tried Hara though. Need to see her soon.
