A few years back I was contacted by a guy who said his Mistress had told him he needed to seek out and submit to another man sexually. He'd never had sexual contact with another male but was doing as he'd been told even though it made him a little nervous at first talking about it. After a few emails and phone calls he showed up at my door; nice looking guy with longish hair and a quiet demeanor who didn't seem at all nervous or hesitant. We chatted for awhile and I asked him questions about his sexual explorations and though they were quite involved with women he'd simply never done anything with a guy.
I asked him to undress, which he did silently and then stood in front of me naked waiting for his next instructions. His flaccid cock was huge, bigger than most guys when they're hard. I commented on it and he shrugged his shoulders. I walked over and cupped his balls in my hand - they were amazingly big too and hung low beyond the bottom of his cock. He wasn't aroused at all and just stood there completely submissive and quiet. I fondled him for a few seconds and then asked him to go into the bathroom and kneel over the edge of the tub.
I had prepared a clean two quart enema bag for him and filled it with warm water and a little bit of Dr Bronner's castille soap. He had no idea what I was doing and didn't ask. I explained that I was going to fill him with two quarts of water and that I wanted him to take all of it without speaking and without making a sound. He never looked around behind him to see what I was doing. I inserted the nozzle without lube so that it'd stay in better and then opened the flow and began filling him.
Surprisingly he took the full two quarts without even a moan. Before the bag emptied I refilled it with another two quarts and he took those ontop of the previous two, again without making a sound or saying a word. I knew his guts were churning and cramping at this point because I could see his belly heaving and his anus puckering and struggling to keep the water in. Not a drop of the gallon of hot soapy water leaked out of him though and he just stayed there kneeled over the edge of the tub in silence. I was in awe as I know from personal experience how difficult it is to take a gallon enema, much less hold it in after the filling.
I pulled the nozzle out of him and stood there watching for a few minutes wondering when he'd cave and need to expel. He didn't, so I finally told him to stand up slowly and sit on the toilet. His cock was hard by now and his foreskin pulled back a little over the head. He didn't touch himself - he just sat on the toilet and slowly began to expel with his hardon sticking up between his legs. I told him he could pee if he needed to but he didn't. I stood there and watched him for several minutes as he finished expelling in complete silence. I told him it was OK if he wanted to moan or talk now; he didn't talk but the groans were a clear indication of the discomfort he was in.
When it appeared as though he'd completely flushed out I asked him if he wanted to go another round. He looked up for the first time and said, "If you want me to." His submission was finely tuned and it was obvious he would defer to me no matter what. I had him kneel over the tub again and began the second filling. This time he wasn't able to take as much and we stopped at a little over two quarts. His hardon remained strong throughout. When the second filling was completely flushed I wiped him off and took him into the living room where I had him lay on his belly on a towel on the floor. I spread his legs apart, lubed him and fucked him for almost an hour in different positions, all of which he got into without a word of protest.
When I got too tired to keep going I told him to kneel in front of me and masturbate himself while I watched. Without looking up at me he got himself off and spread a huge amount of cum on the floor between us; his body jerking from the orgasm while still in complete silence. Normally this would be the point where a person gets up, gets dressed and leaves. I had him stay naked though while I cleaned things up and then asked him to masturbate me before allowing him to get dressed and leave. At this point I realized he'd never touched a man's cock before because he did it awkwardly and I had to coach him a little on how to do it. It was obvious he had no interest in my genitals - he was just doing what he'd been told to do. I came on his hand and after my orgasm had subsided I reached for a towel and wiped it off.
We got dressed and then sat and talked for awhile longer. I asked him what he thought of the experience and he said it was interesting and that he had a lot to tell his Mistress about what had happened. I invited him to return if he wanted to but he said that was up to her. And he left. We communicated a couple of times after that but I moved from the area and never saw him again. I'm still in awe of how submissive and quiet he was and how he managed to take a full gallon of hot soapy water without making a sound and without even really knowing what was being done to him. It was an amazing experience to be on my end of it since I'm not a dom and had no previous experience exerting my will on a sub.
