Naughty Mature Playing on the Stairs

I had been shopping and when I came back to my apartment the Lift was Broken so I had to climb the stairs in my Heels, I dont know how many flights but a Lot! and when I got to the top I realised I had forgotten my key, so I went and sat on the stairs and as I was feeling Hot & Horny I decided to strip off and play so off came my top then my skirt revealing my sexy new lingerie, but my Bra was soon off and I started playing with my tits and tweaking my nipples, then I slowly removed my panties and started to rub my clit then finger my wet juicy pussy, I was really getting excited and finger fucked myself fast and hard until I reached Orgasm then sucked all my cum from my fingers then picked up my stuff and went back to wait by the door but I pushed it and it opened, I must have left it on the latch.
