Hot Spot Kiss

My boyfriend's 'spot' is on his ears. So, when we make out, I start off by kissing his lips, then kiss along the cheek until I reach the side of his head, kissing and nibbling at his ears. This gets him real excited. Then I kiss my way back to his lips, continuing our "necking" session.
Whatever your partner's 'spot' is, I suggest incorporating that area into your kissing.
