Thanks again Zenra! I guess the next question would be how do I get it in there? I was thinking a large opening syringe since it won't leave much left overs compared to squeeze bottle of some sort. I would want the opening large enough to get something thick in there but small enough not to hurt (let's assume she's never done anal before). So I would think a finger or two wide. Found this
