Step-sisters tights/pantyhose (true story)

this happened about 2 years ago when i met up with my step-sister who i hadn't seen for a number of years but we got in touch via a social media site. she's 31 now and a few years younger than me. before we met i told her about my crossdressing which she was aware of and she was fine with this and said i could take a change of clothes to hers. we went out for a meal and a few drinks then went back to hers for some more drinks and i got changed into a dress, tights and heels. later after some more drinks i managed to persuade her to change into a skirt and pair of black opaque tights for a short while and i was able to rub her legs in her tights for a bit (she hates people touching her feet so i couldn't do this unfortunately as i love feet in tights!). she also gave me to take away a pair of sheer black pattern tights with ribbons up the back, 3 pairs of sheer silk french knickers and a black silk nightie as well so needless to say i have enjoyed wearing them on numerous occasions.
