I did sockjob and footjob on my biggest dildo which is 20 cm ! First I played with it in my socks and then slowly took them off and started doing it without. I hope I'm doing well ^^ because I'm still practicing and as you know practice makes perfect! Of course, I didn't forget to moisten it properly and spit on it so that if it was your dick it would surely be much more enjoyable for you. Hope you like it !
