Shoesession

I have only fucked shoes a hand full of times. It feels amazing and nothing turns me on like it. But ive never been able to finish properly. I am afraid to cum in them because i dont know how to clean them off so that the soles arentbsticky or stained. I know that a lot of you find that leaving a mess is the best part, but im too afraid ill get caught. Could someone please tell me how to clean cum out of different kinds of shoes (flats, flip flops, high heels, etc) so that its like it never even happened?
Thanks
P.S Keep in mind that you helping me means more pictures and videos for you in the future.

I usually ask my boyfriend to keep my shoes cleaned after our (his) games. Sometime he forget to clean my shoes ("forget"....) but if I'm present, I ask him to use some cleanex or adsorbent paper (like kitchen paper). If you want to do a perfect work, put a little bit of water on the paper and clean again. For the outside you need the soft cotton (your T-shirt?), to remove every matt spot...
