my local dollar store sells sex toys! ok...thats a bit of a stretch but i stumbled upon an item that peaked my curiosity. it fits inside a plastic screw top cup as an insert - approx 5 1/2 inches and thin. i like cold play (and coldplay) so this wuz a nice sensation, like a mini ice dildo that doesnt melt and can re-freeze. the temp difference at insertion is quite the chill thrill.
i recommend like anythin, enter at ya own risk.
