Sandwiched Between a Mean Senpai and a Big Kouhai for a Simultaneous Attack!? ~Teased Above and Below Until I'm Melting~
Ijiwaru Senpai to Ooki na Kouhaki ni Hasamare Douji-zeme!?

Kojika is an office worker with little experience in romance and a secret hobby: writing self-insert fantasy stories online. Her steamy threesome fiction features two popular colleagues, Kosaka, the company’s top salesman, and Inukai, a sincere and well-liked junior who attended the same university as she did. When Kojika goes drinking with the two men, their conversation turns candid. Kosaka suddenly recognizes her writing account and confronts her about the stories starring him and Inukai. Her secret exposed, Kojika finds herself caught up in an encounter that resembles the fantasy she had imagined, even as she wonders whether she will really go through with it.
