The Ultimate Wank...?

trapped in a rubber bondage-bag, with my hyper-sensitive eight inches exposed thru a small opening,,,four fingers curled round my shaft, the thumb slowly 'polishing' the sensitive head, endlessly in a process of orgasm-denial...at some stage I will promise ANYTHING for it to go on, without end...have even been known to defecate helplessly, at the strength of the denial, but as I lie in my own mess, all I can think about is more - always more...just need a control freak to see that happens...either sex, any age weight or appearance...
