worked in a nursing home for a couple of years quite a while back.
did the majority of my shifts with a pleasant, (seemingly) straight-laced middle-aged woman, she had two teenaged kids, would have been mid-40's.
we always got along well, she was very supportive while I learned the job and would also occasionally give me a lift home after work.
from time to time she would also compliment me on my looks, but in a very subtle way, so that I couldn't be sure if she was flirting or just being nice.
this went on for about 18 months, and very slowly over time she became slightly more forward in her flirtations.
one evening all hell broke loose; she paid me a compliment and I returned it, telling her I thought she was quite attractive (she was ok).
one thing led to another, and before I knew it she was on her knees in a darkened, *but occupied* nursing home room (there were two highly dependent oldies in the room, asleep, but even if they weren't they weren't exactly with it, dementia is a bitch ..)
from that moment on she routinely surprised me with her willingness to take risks in order to satisfy whatever desires she had - we would meet briefly before work and she would blow me, she would blow me at work quite regularly too.
finally one night after we had completed most of our duties she just looked at me intently and said 'come on' - she then led me up to the toilet, dragged me in, dropped her pants, sat me down and rode me like cowgirl.
it was pretty daring as any other staff member could have walked in at any time.
in the end I left the job, but not without some regret, as she wasnt the only chick I had some success with there - so, in summary, I suppose she was 'strange' (thus fitting the criteria of this thread) as she seemed so Mumsy and nice, but in reality was a raving knob fiend.
nice lady.
sounds like fun
