Couple seeking beautiful slim young F

I will be in San Francisco March 12-14 on business and I want to surprise my female friend with a female play toy. She is stunning, sweet, very slim, mid 20s, blond and has longtime fantasies about being with a similarly proportioned young girl. Must be young, thin and genuinely interested.  Submissive a plus. I am VGL mid 40s professional and we have are seeing each other after a prolonged absence.
