Crazy horny for mother in law

It started off really innocently, didn't really care much for her or had any feelings for her.. As her main job involved cleaning, i thought the best win/win situation would be if i got her to clean my flat and still pay her. When she started she used to wear shoes, then slowly moved into flipflops... she always used to carry around her big bag full of crap, i then noticed a few times she brings her shoes, only to take them off for a full view! (see below).
I can't believe my luck, she is in the kitchen singing while cleaning, i carefully peak out of my room and keep watching like a meerkat, making sure she doesn't suddenly walk out in the hallway. i grab one of the shoes, the left one in this instance, i then scramble back into the room, sniffing the fuck out of her shoe, it smells good, she looks after her feet well, she has wide shoes, perfect for a full face submerge. My boner is massive, i whip out my cock while sniffing her delicious scent and i cum, it was so overpowering i had to try so hard not to grunt! I stand there almost dropping the shoe, i grab my cock so hard while pushing it back down into my pants and my cum won't stop, it keeps pumping, i can feel it dripping down my leg. My heartbeat is so hard/fast i can feel it pumping out of my chest/head/ears, my arms are shaking and i quickly place the left shoe down on the right shoe (more or less as i saw them) and then take a photo of them with my phone.

Meanwhile, she has no idea, and was still singing while cleaning in the kitchen ;)
