The usual veggies and nobody mentioned an extra large saltwater fishing plug (with hooks removed, duh). Use an extra strong latex condom (Trojan Magnum etc) for insurance in case you need to recapture it having gone to deep,,.
Seriously be extremely careful and use common sense. A
disclaimer is needed here as I have
never tried the the last one and I don't know if its a safe idea so please if there are any young impressionable people here this is
not an endorsement just a thought. Probably very unsafe!
I just wish I could find a place to stash my toys as I keep having to purge my collection every time I move.
