Yes, sounds right to me... In addition (if appropriate, LOL), do not just put your hands 1) solidly on her back 2) right next to each other and 3) stand too far away, bent over towards her.
Nope.... You want to 1) place one hand higher than the other on her back. 2) Do it somewhat lightly, because you want to perform some kino with those hands by moving them with a subtle stroke.... For some reason, my preference is to begin the hug with my hands furthest apart, one higher and one lower on her back, and slowly and semi-lightly move them closer together. 3) You want the front of your body to really touch hers. Your toes should be right next to hers, which lines up the rest of you for maximum contact... This upright posture can allow her to really feel the muscles of you back... how good and manly you smell... the electricity of any sexual tension that might be present....
These few subtle things make the difference between hugging aunt Bessie and the HB8 you think you have a shot with.
