My hubby and I talked about this question and pretty much were in total agreement on why we enjoy enemas.
First, it is having your partner nude and in total submission, seeing all the curves of the body, the firmness of the butt, and the opportunity to do just about anything to pleasure your partner.
Second, we both occassionally like to take enemas while being across the lap of the giver. Both he and I enjoy the carressing touches during the application of the lubricant, the massaging and the feel during this process.
Third, the insertion, especially when a larger (but not too large) as nozzle is used. I love when he inserts, plays with me, and brings me almost the climax, while he enjoys having the nozzle moved, pulled partially out and re-inserted, played with and having me touch his most sensitive areas, without bringing him to climax.
Fourth, enjoying receiving the liquid, usually not an overbearing amount, but enough to take some time and provide enjoyment to the recipient.
Fifth, when we pleasure each other out of doors, we'll sometimes administer to each other before taking relief of ourselves ... if I receive first, I administer to him, etc., ... then we both use the outdoor privy, a two-holer. There's something unique about being with your partner when you're relieving. We'll even do this for the second or third enemas ... it is a real kick, if you know what I mean.
What is the appeal of giving or receivng an enema? I think I've pretty much explained why we get so much pleasure out of this recreation. How about you?
