Chiyuki's nipples were aroused when she saw Arthur giving love to Yuuki's nipples she did not produce a drop of breast milk.
She wanted to feel the intimacy that was shared in making love to the three of them, making her body unconsciously move to hug Arthur's naked body.
"Master Arthur, have you forgotten about me?" said Chiyuki to tease Arthur who was focused on giving a loving kiss to Yuuki's nipples.
Kruuukkk...
During the situation filled with intimacy and sexual desire, a hungry stomach growled and indicated that someone was hungry.
"Is that from your hungry voice, Yuuki?" Arthur stopped his small movements that gave love to Yuuki's nipples.
"Master Arthur, I just had lunch. I'm not that greedy to be hungry again after enjoying lunch outside," replied Yuuki while shaking her head.
