Unfortunately, I don't have any sisters, just a brother.
Now, I'm an 'E' cup, so they're out there. I like to show off cleavage, because normally I'm a city bureaucrat, middle management, so I get to be about as sexy as a black bra. On weekends, though, low cut bodysuit, tiny skirt, some nice 'FM' heels ... now if I could only save up enough to pay for that final 'snip'. Maybe I'll do the medical tourist bit and go down to Cuba ...
