Mantis, Cicada, Oriole: A Triple-Cross Bondage Saga by Liya

In a meticulously planned act of deception, Hayasaka Ai, while assisting Kaguya with her studies, employs a drugged handkerchief to render Kaguya unconscious. She then secures Kaguya's legs in an M-shaped spread, using intimate toys to induce multiple orgasms.

Unbeknownst to Hayasaka, a third party has been observing. They incapacitate Hayasaka, leading to both women being bound. Their captors then engage in further play with both subjects before absconding, leaving the women unconscious and their socks as the only trace.
