Advice on couples vibrator?

Hi.

My girlfriend and I want to buy a "couples vibrator", but we're having trouble deciding on which and wondered if any of you had any experiences to offer.

We're considering amongst these, but maybe there are others?

She usually requires both internal and external stimuli to have an orgasm. We have tried some normal vibrators, but she would prefer not having to hold it in place - having her hands free.

Does anyone have any advice to offer?

 

Get a realdoe and put the small end in your rear and DP her

 

We have a cock ring with a bunny on the end that vibrates, when ifuk her an she's on top she just gets crazy and fuks me real hard. She just totally looses control an just goes for the pleasure which is a turn on seeing her eyes close an watching her orgasm
