His hand was on the rail on her side while his other hand grabbed her glass and finished her wine before putting it down.The way his Adam's apple moved with his every violent gulp made her feel a tickling heat around her nape.When he brought his attention back to her, he licked his lips to wipe off the trace of wine.“How shall I make it up to you then?” he asked with his deep voice, like a seductive devil asking his victim how she would like to be killed.
