Simon continued to purr and he groaned softly while gently gripping Naoki's hair. "Good boy..." he panted softly.

Naoki thought it felt strange to be called a good boy.. but he just continued, getting in the process to Simon's nipple. Wanting to tease him he bit it rather softly.

Simon actually moaned from his nipples being licked, being surprisingly sensitive there and he found himself arching into the licking.

Seeing that reaction Naoki felt a bit agitated and decided to bite the nipple he was licking few moments ago. Would that make Simon moan too? Being curious creature he always was he needed to check it out.

Simon jumped a little and a more lewd moan escaped him before he could bite it down upon his nipple being bit.

Naoki grinned and leaned over him, his eyes glistening mischievously.
"You like pain?", he teased.

"I do...it's an addiction of mine." Simon replied with a lol of lust at the neko.

"Pain? Really?", asked Naoki, really curious now and forgetting about continuing. "How does it work?"

"Just...keep biting...not in the same spot, just...anywhere. Scratch me too of you want." Simon replied, his voice becoming more heated as he talked and he felt precum spill from his member inside his pants again.

With a small amused chuckle Naoki leaned over and bit into the other nipple. He made sure to make it hard. Though he forgot about his fangs and saw the blood trickling. Quite startled he looked at Simon.
