A broken moan slipped from Zhao Bolin's lips. He could not actually describe what he was feeling right now. At first, Lu Yizhou's tongue still retained a hint of warmth as he licked and sucked his nipple, sending sparks of glorious electricity down his spine; but gradually, everything cooled down. Not to room temperature, but the kind of chill that made his teeth chatter.
Goodness, it… it was just like putting a soft ice cube down his chest! What kind of torture was this?!
Not only did Lu Yizhou use the tip of his tongue to tease his sensitive nipple back and forth, he also bit down without any preamble, creating a distinct circular teeth mark around his chest! Professor Zhao was so alarmed that he cried out, "Don't—!" He still had a lot of things to experiment with, he did not want to turn into a zombie who could only think of spreading the virus to humans!
