Theo wasted no time, he immediately teasing Damien's nipples once more. This time, Damien had been prepared for the touch and bit down on his lip, determined not to let any more sounds escape.
Theo seemed to be enjoying watching Damien struggle to keep his composure, taking pleasure in his reactions.
Theo, after testing Damien's reactions by lightly teasing his nipples, began to gently trace circles around them with his fingers.
"...!?"
A shiver, almost like a cold sensation, ran down Damien's spine, causing his whole body to tremble. Unlike the sporadic pleasure from before, this continuous stimulation relentlessly attacked his senses. Damien managed to hold back his voice, but the overwhelming pleasure was building up inside him.
He knew it would be easier if he just let the sounds out, but the sweet, embarrassing voice from earlier was something he couldn't bear to hear again, so he desperately suppressed it. But he was nearing his limit.
