I am a very hetero woman. I've never had any interest in any form of sex with another woman. It's just not my thing. However, although all of my fantasy's are male oriented, one of my fantasy's since I was in my 20's was to have an e-nurse come to my home or I'd meet her somewhere. In some cases she was a very pretty woman dressed in a short white nurse dress with stockings and a white lace garter belt. She'd always have a great appreciation for enemas so she'd know what to do. She understands the sexual arousal and in some cases asks if I'd like to use a vibrator. In some cases she hands it to me and in others she inserts the vibrator for me very gently and lovingly but not sexually. Of course since she is an enema lover as well, she knows all of the key words and phrases to use to send me over the edge. It would be a nice long session and very pleasurable but that's as far as it would go. I never had any desire for it to go any further than that. In some versions of the fantasy there would just a be a more stern woman that was not sexy at all. Again, no sexual activity between us. I love the intimate, erotic pleasures of an enema. That's my main interest however, there is an aspect of it that I enjoy now and then and that's the humiliation of it. I think this fantasy combines both of those aspects in a way.
With that said, it is a fantasy. If the opportunity presented itself and I had the opportunity to make the fantasy real... I would.
