Scarlett closes the autumn quarter with all As, buoyed by Dr. Carlsen’s plus in computational biology. She credits therapy with Sam for her calm about minor grade nuances. Tension with her roommate Maryam persists after a drunken outburst, but Scarlett lets it slide. Lukas spends the night, leaves early for practice, and they plan to brief Zach on their project.

At the library, Lukas pulls Scarlett into a single-stall restroom and brings her to the brink before denying her climax, asserting confident control and instructing her to go ahead to the meeting. During the update with Zach, Scarlett struggles to focus through arousal while fielding casual questions and presenting her neural network. Lukas praises her model’s markedly better accuracy, and the meeting concludes uneventfully.

Immediately afterward, Lukas returns to the restroom and, moved by how impressed he is with her work, gives Scarlett release. He quickly pushes her over the edge, then continues until she rides multiple orgasms, encouraging her to endure “one more minute,” which she consents to and manages, reinforcing their negotiated power dynamic.

Finally, Lukas keeps Scarlett kneeling while he masturbates, denying her request to reciprocate because he prefers to control the interaction. He frames her as his willing, cherished partner, using praise and ownership language, and finishes by coming in her mouth. The encounter leaves Scarlett affirmed both by his approval and by the success of her model, entwining academic validation with their deepening D/s bond.
