Choppiri M na Shirubii Senpai Part 1

 After a small office party, mentor Silvi invites herself into her junior’s room and the mutual crush neither of them had named becomes a night they cannot walk back. What starts as clumsy, wanted sex slowly tips into rope, toys, and the soft masochism she had not admitted out loud. Realistic 3DCG, full voice, and a novel half that keeps the office relationship in the frame.

Summary (about 200 words): Silvi is the junior’s training senior: beautiful, easy to talk to, and someone he already respects more than he lets on. After they close a large job, a small drinking party leaves her bold enough to ask for a bed. She half-pushes her way into his room and, as a “lodging fee,” hikes her clothes and offers her breasts. He refuses, more confused than unwilling, then says what he has been holding back: he likes her, and he does not want alcohol to wreck the working relationship. She smiles and answers that she is not doing this because she is drunk. She has liked him for a while.

That night they sleep together because they both want to. From there the relationship deepens fast. Early scenes stay close and ordinary—missionary, oral, cowgirl, side—while the novel tracks how a respected senpai and her junior stop pretending the attraction is one-sided. As they keep meeting, tastes neither of them had named start to surface. Rope, restraints, and toys enter the sex. Shame and a little pain get tied to pleasure, and the power between them shifts without the affection dropping out. An extra scene brings a vibrator to her company desk. The package pairs a Windows story app (free mode and scene jump) with MP4s of every novel and sex scene, including separate files for the H scenes alone.
