Being together in the gym shower and seeing Jeff standing completely naked—with his muscular body, and his rod still aroused and throbbing in erection—made Nubia realize how manly Jeff had become compared to her ex-boyfriend.
She had always seen Jeff as her gofer or little brother before. But now, to Nubia, Jeff looked like a predator who would devour and ravish her if she ever gave her consent.
And she was almost on the verge of giving that consent, even though he wasn't asking for it yet.
"Aren't you the one who invited me to shower together? So why are you getting shy all of a sudden, Nubia-senpai?"
Of course, she was feeling shy and flustered—she wasn't used to this kind of intimacy after all. But that didn't mean she wasn't aroused and excited, imagining how it would feel to be penetrated by a rod as massive as Jeff's.
However, doing it with Jeff meant they would be cheating on Jess. And Nubia didn't want to be the reason Jeff and Jess's relationship was ruined.
