Rectifying the Situation
Kirk manages to get himself turned into a girl for 48hrs or so, and of course once he’s been deemed healthy he runs off to have some fun, alone, in his room. Spock walks in later to find Kirk frantically finger-fucking himself but not quite able to get himself (herself?) to orgasm… it is only logical that Spock rectify this situation. Multiple times. After making Kirk beg for it. Perhaps he will then allow Kirk to fuck himself on his cock and finally let him get off by himself.*
