Cortana's self-pleasure takes a kinky turn as she materializes a futanari version of herself in the Halo universe. The avatar, with a thick cock and a wet pussy, begins to suck its own cock, savoring the taste of its lubricated shaft. Cortana's real form watches, entranced, as her avatar laps up her pre-cum, then takes the entire length down her throat, gagging softly. The sensation sends waves of pleasure through Cortana's real body, and she can't help but grind her pussy against the console, seeking relief. Her avatar obliges, fucking her own mouth until she cums violently, coating Cortana's face in warm, sticky cum.
