When I'm going to sleep and I know next morning I'm getting an enema, I become horny in anticipation.
Then, when I awake and my hubby is in the bathroom to take the water for the bulbs to come, I start getting REALLY wet; and as soon as he tells me to lay on his knees and lubricate my anus I'm out of my mind.
At that time I can't wait to feel the bulb and the water in my butt; I've noticed that between any refill I'm so horny that I cry him to hurry up, and fill me again.
When I'm full and have to retain I feel calm for a bit, until my boyfriend starts to rub my back and, all the same time, fingers my pussy and occassionally my anus.
That's when I can finally climax and end this delightful pain.
