The Big Sister I Admired Was an Otokonoko ~The Daily Life of Crossdressing Siblings~

Left alone in the vast mansion while our parents were away on business, it was just me and my sister.
The quiet mansion gradually filled with a sweet yet dangerous atmosphere.
Even she, who was usually cold toward me, showed a different side of herself on those nights alone together.
Her adorable sleeping form, wrapped in loose pajamas. The soft curve of her chest peeking out from the hem, her smooth white skin—everything about her sent my heart racing.
Every time I felt her vulnerable, sweet breath, the forbidden desire I had suppressed deep within my heart began to stir.
“I can’t take it anymore…”
Overwhelmed by uncontrollable feelings, I finally break the taboo of sibling relations and resolve to claim my sister as my own. However, during this summer vacation, not only my sister but also the attractive girls around me seem to harbor secret feelings for me. A one-month limited cohabitation—can I suppress the throbbing of my heart tainted by sin?
The period is just one month. The forbidden sibling cohabitation begins now—♡

One day, Taiki finds himself living under the same roof as two older women.
They look down on him, dump all the chores on him, and treat him like their personal errand boy.
"How long is this going to go on...?"
Nursing his frustration in silence, Taiki one day hears a strange rumor.
— That there exists a device capable of influencing a person's consciousness and "tuning" their behavior.
When he gets his hands on one through a shady mail-order site and puts it to the test, his quiet everyday life changes completely.
Hidden instincts beneath a tough exterior, an overprotective maternal side, and a terrifyingly sharp business sense—
The true selves the two women had kept buried deep inside begin to surface, one by one.
And in that moment, humiliation begins to give way to a sweet, dangerous reversal of control.
