Eguchi Miki

The third daughter of the Eguchi family. She serves as student council president at Shitama Academy, where she attends.

Among her siblings, she has a natural leadership quality that makes her take charge of situations. Despite being only a few months older than the protagonist, Yuu, she acts like a big sister and constantly meddles in his affairs.

"Yu! Swear that you'll call me big sis for life!"

Miki-nee, who is also the protagonist's classmate. She constantly acts like his big sister, but in reality, she has a significant aversion to oral sex.

However, fueled by her affection for the protagonist, watch the drama unfold as she gradually gets better! Miki's specialty is her affection-filled tail-style oral sex!

She wraps her long hair around his shaft, teasingly flicking it with her tongue at times, coating it generously with saliva all the way to the base, tormenting him.
