The Tight Shoelace

I like bdsm and especially haveing my cock tied up..while i masturbate i like to tie my cock and balls up tightly with a shoelace once i have i well lubed and hard. then as it thobs away i can stroke it and pet it while the tension builds. when you cum its like its about to break the binds off and its quite intense. even more so if you are doing some anal stim as the same time.
