Thought I would bump this thread as its relevant to me recently and share this.
I had my first proper "humiliation sex" act only just recently. I recently engaged in a threesome, with my partner and his mate and we stayed the night all together at his mate's place. Now sure during our threesome, I did engage in some various acts, that I found degrading and humiliating which I enjoyed and added to my pleasure but its different when you are horny as a lot of things excite you, but the next day was where things became interesting.
My partner and his mate were sitting in the lounge room, reading the paper when my partner asked me to get them both a cup of coffee. Note earlier he had already brought to me a cooked breakfast in bed as I had slept in from the night before. So I returned to them with two cups of coffee and gave one to my partner and one to his mate. He then asked me if I could suck on his cock while he read the paper and enjoy his late morning coffee. He said he didnt want to blow, he just wanted to sit back and relax and enjoy me sucking while he was chilling out and chatting with his mate.
In those first few seconds of the request, I processed that he was clearly wanting to show off in front of his mate and demonstrate his control and power over me and have on display his alpha male abilities. I could have easily said no and that I was "tired" and or "not in the mood" without any issues, but his ego would have been bruised in front of his mate. Now in fairness to my partner he knows when I am tired, but the fact I came into the lounge room fully rested, wide awake with a big smile on my face from our night before, that this wasnt really a big deal and he was just wanting to show off a bit.
I smiled to him and said "Sure it will be my pleasure", I got on my knees and pulled down his underwear and began sucking on him, while he was reading the paper and chilling out and kept my focus of attention looking at his mate the entire time. I felt dirty, cheap and used, but in a good way. It was when you think about it a degrading and humilating act to be controlled and dominated in this manner, but for me I enjoyed it and I knew he could tell that too. He liked making me his bitch that he owns and controls.
He actually asked me later that day when it was just the two of us alone and apologized if he had crossed a boundary with me. I laughed and said you know what I like and dont like and you have never crossed a line with me ever that I didnt want to willingly cross myself. I could have easily said No to you and you wouldnt have thought any differently.
What I found interesting is that with girlfriends I have had in the past, I would never have dreamed of asking for this from them outside of sex. Only because I know with girls, not only is it degrading and humilating for at least the girls I have been with, it would have probably led to a fight and or a breakup.
