I'm looking for vids where the guys is fucking and he makes animal Noises, I think its a huge turn on, Especially if he's cumming! And to listen/look and the girls reaction!
If I remember correctly, I think it's in this Samantha Milf Hunter(the one who wears the blue top in the beginning) clip entitled "Clit n Pendulum." During doggy style. He starts swinging his arms and yell like an Opera singer. It's not exactly an animal sound but it's interesting. The only hard part is actually finding the clip.
