My girlfriend has had a kink I suppose or interest in feeling a bit like prey, one of the parts is being salivated on, is there any way to salivate more like on command? I think of how much spit I get when I feel really nauseous and obviously I don’t want to feel nauseous but being able to produce that much saliva on command would really make her day I’m sure. Any suggestions on how to produce more saliva on command? Thanks.
