Another postscript. She's now at apartments near the City Centre, so a lot more discreet, but the room was very warm.
She was a bit lethargic at times and I do feel that the effort level has diminished slightly on each subsequent visit, or maybe it's my excitement level, so I may have run my course with her. There were still nice touches as she danced down the hallway, cradled & caressed my head gently as I did RO and some nice eye contact and playful responses.
She is still definitely a very attractive nubile teenager and her attitude & enthusiasm are well above average for the area.
