Buy the accessories at once because they not expensive and so you save the cost of transport.
Speed controller is mandatory because this vibe is so powerfull, and like you know sensuality start always slow and soft, this beast start strong and wild, you not.
Here an idea about the different accessories available:

Another "game" when she is riding him, she can shove a sort of dildo mounted on the vibe in her ass, him will be massaged by her hole tightened vagina, she have control of his feelings, seeing him on the edge and then feeling cumming inside herself, just imagine what you can share and offer to your partner.
This is not publicity for an e-shop I use this shop because they have nice pictures and a large choice.
