I've had an enema from a male Dom I visited a while back. Once I was naked he bent me forward over a massage bench and started to penetrate me, first with thumb then with a long double-ended dildo. After doing that for a while, and let me tell you it was very nice!, he said that I needed cleaning out, so laid me back on the table and put my heels in stirrups so my legs were spread and anus accessible. Then he filled me with two large bags of water, left it for a few minutes while he caressed my cock and nipples, then as I started to get cramps moved me through to the bathroom. There I sat on the throne and simply evacuated for minutes! While I was doing this he stood in front of me, playing with my nips with the crotch of his briefs in front of my face. It seemed natural to slide his briefs off, then take his half erect cock in my mouth and suck and caress it to hardness. It was the first cock I'd sucked and was wonderful. He didn't let me suck him off, but made me clean up, then we returned to the massage table where he brought me off by electro stim. It was an amazing experience.
