We went together to a sex shop to buy Poppers but when she saw the dildos, she was attracted to them, so I looked with her several and we bought one which allows to introduce a liquid inside in order to make it gush into it.
She has already used it several times (it must be said, that it is much larger than my little tail) but we have not yet tried to put the liquid inside.
As for the sexy outfits to go to the sex shop, you should not offer her: she loves it!
