Once I had my fill of his very sensitive chest, I brought my lips up to the side of his neck, giving him kisses, light sucks, tongue flicks and gentle bites. Each action just keeps on making him utter lewd sounds involuntary.
My actions made him realize that it won't help him one bit even if he tries to keep his lips sealed or as he bites his lower lip to keep himself silent. The more he tries to keep himself quiet, the more it encourages me to do naughtier things to him to get stronger reactions from his body.
I made sure to explore both sides of his neck and even bit his earlobes for fun. I continued as I went down to his shoulders and then his chest again as I left hickeys of different shades and sizes on his skin as I went down on his body slowly. I bit his nipples gently one after the other to tease him further. He groaned in surprise at the slight pain that it must have given him.
