Olympic diver Tom Daley needs to prepare himself for possible kidnap and captivity scenarios…
…he may find himself abducted and locked into these…
…or tied like this…
…or facing harsh metal bondage like this…
…or kept in underwater bondage like this…
…how would you keep the speedo clad athlete restrained?
Heavy Bondage 
more!more!more!
the pic showing the guy in heavy metal restraints is just so good .Where did it get sourced from ?
Looks like it was a profile from Gearfetish. The profile doesn’t seem to be there anymore. Have you tried doing a reverse image search on Google or Tineye?
