R E A L I T Y !
My favorite enema videos are ones that deal with a female not feeling well. Her mom, best friend, doctor, or nurse takes her temp (rectally, of course). Her temp is normal, and after questioning, she admits that she hasn't moved her bowels for 3 days or so and that the Milk of Magnesia hasn't produced results. It is then that an enema is suggested. Never having had an enema before, the process has to be explained to her. Being modest and shy, she asks if she could try pills instead. She is told that the enema will give her relief quicker than any laxatives. She is reassured that it will not hurt and that she should not be embarrassed. She sheepishly agrees to the enema.
At enema time, I prefer her to be in the knee-chest position, but left side is OK. Each step is explained to her to reassure her. I want to see her butt lubricated as well as the nozzle and definitely want close-up shots of lubrication and nozzle insertion. Being one who enjoys giving enemas gently, I would want dialogue about minor cramping, stopping and restarting the flow, abdominal massage, etc.
I am not into watching expulsion, so my video would end with nozzle withdrawal, abdominal massage while she is on her back, to aid her in retaining the enema. Her expressing the need to expel (fade to black) Video resumes with her returning to the bedroom saying how much better she felt.
If the giver were her best friend, I wouldn't mind having her friend indicate that she too, could use an enema and have the roles reversed and the girl could have a lesson in administering so that she could, if necessary, self-administer the next time if nobody is available to assist.
I would want decent acting, and as stated before, lots of close-up shots.
