I adore rabbits its one of my favorite toys, I have Mr Big.They usualy give me the biggest orgasm with having both the penetration and clit stimulation OMG they are an incredible invention.I could kiss the inventor.....no really I could its the best toy apart fom my wands.Mmmmwahhhh!
Let her see and hold the vibe and try the vibrations on her own first just in her hands, so she can feel they are nothing too intensive, often the noise of these can put people off, so let her see all the rotations and vibes.
You never know she may take things from there herself, i did on my first time...eeek all those years ago lol!
I agree with Buddyboy start without anything turned on, (but be aware its easy to press those buttons by accident in the heat of the moment), then turn on just the vibration on the lowest setting.This will set the bunny ears off on gentle but you can still feel the vibes down the shaft a little, then with lube gently work your way in as she is comfortable,
Once inserted try a rotation if your rabbit has one,( i cant remember if the g-spot rabbits have them), but if they do; be aware too I personally always have a direction i prefer, some girls have been known to be uncomfortable with a certain direction depending on their personal anatomy.
Especially as your rabbit is a G-spot version a rotation will be extra pointy and could be uncomfortable, just take things slowly as always.
I prefer one direction, the other doesnt do much for me thats all, so tell her when your going to do this and see how she reacts without using any thrusting movements. Then work your way up the bunny speeds.
I must admit I I dont like my rabbits being thrusted in and out that much while the head is rotating, but thats just me and I generally orgasm within minutes without any movement at all, just with everything on full speed lol!
Good luck and Im sure she will love this toy, i adore my rabbits each one is different. If youve anymore questions just ask, you will always get an answer on here.
