A few years back, I was dating a girl who was willing to experiment sexually. We spent a lot of evenings trying things and sharing fantasies. It turned out that we had several fantasies in common involving the exchanging of power. She was very dominant sexually, and I was more than willing to allow her to experiment on me, because the rewards were always more than worth it.
One night, she told me about a fantasy she'd had since junior high: She fantasized about hypnotizing her class and then making them do things for her amusement. One particularly vivid image that stays with me today is one involving her teacher. She imagined making her teacher believe that she was a horse, and attaching reins to her nipples. Then she would climb on her back and ride her around the school while all the other students, her slaves, followed obediently.
I was floored. First, the idea of giving conscious control away was something I'd always found attractive. Second, the fact that she was having such sexually explicit fantasies when she was twelve years old!
I agreed to let her hypnotize me, and we started that night. It turns out that she had a small library of books dedicated to hypnosis and methods of induction. The first night, things were pretty tame: She just had me relax and she guided me through a few (sexual) imagination exercises. I don't think I was hypnotized deeply, if at all. But it felt great.
Over the next few weeks, she experimented with different types of induction. The one that seemed to work the best was to imagine that I was walking slowly down a winding stone staircase into darkness. The sound of the echoes of my footsteps in my mind, the darkness, the moving in circles, they all combined to help distance me from the room around me. After a few weeks, she felt she had me deeply enough to try some experiments. Some worked, some didn't. When she told me that I was thirsty, I spent the rest of the afternoon drinking down water like a fish. When she told me to forget my middle name, it didn't work at all. I think the problem was that, while I really wanted to give her control, she would have to take it from me. I wasn't willing to just hand it to her without any fight at all.
On saturday afternoons, we usually went for a bike ride. We would ride out 10 miles or so, rest, and come back home. I loved riding and she did it for exercise. One saturday before our ride, she told me that she'd like to hypnotize me. This brought about the usual physical responses: quickened heartbeat and breathing, erection, and me saying "okay!" almost before she finished asking.
She put me into a trance slowly, repeating the deepening suggestions over and over, bringing me back to concentrate on her voice, and then releasing me into the swirling darkness again. I have no real gauge of how deeply I was under, but it *felt* deeper than usual. While I was under, she gave me a single posthypnotic suggestion: When we were out on our ride and stopped at the midway point, I would become very aroused. As soon as I was aroused, I would be desperate to make love to her. I would ask, and if she refused, I was to get down on my knees, take off my shirt and begin to beg her to allow me to please her. I would beg her until she agreed or ordered me to stop, but I would be desperate to please her until she allowed me to. She then told me to forget everything that happened while in trance, and brought me back out.
Well, the amnesia didn't work. I of course remembered it all. It was exciting to think about, but I was sure it wouldn't work.
We went for our ride, and at the halfway point I was waiting to see if anything happened. It didn't. I didn't get aroused (but I *wanted* to!) and I didn't beg her to let me give her pleasure. We were both kind of disappointed, and she even talked about giving up on hypnosis. When we got home, she went into the bedroom to get ready for a shower while I put the bikes up in the living room. As I turned toward the bedroom door, I caught sight of her naked body as she stepped out of her shorts. As always, the sight of her filled me with desire.
That's when something weird happened. Suddenly, I absolutely had to make love to her. I couldn't think of anything else. I walked into the bedroom and asked her if we could make love before the shower. She was tired and a little peeved that the hypnosis hadn't worked, and she refused. Suddenly, without any conscious awareness of it, I was taking off my shirt. Slowly, I fell to my knees and began begging her to let me please her. I was promising her anything. I was absolutely in tears with the need to please her.
If I didn't realize what was happening, she caught on immediately. She made me beg for a few more minutes, making me lick the sweat from her armpits, making me clean the bottoms of her feet with my tongue, before she lay back on the bed and allowed my tongue to obey the commands she'd given to me earlier.
Even after she'd come, I couldn't stop. I began begging her again to let me please her again. The only way she was finally able to stop me was to let me come inside her. Once sated, the desperation had somewhat faded, but I still felt a need to nuzzle and lick her body. She was eventually able to get me into the shower, which was a "real" enough activity to break the spell.
I still hadn't realized that I was following her orders, but in the shower, she reminded me of what had happened. I remembered myself ripping off my shirt and falling to my knees, almost as if it were someone else doing it. We never really knew why the suggestion didn't work when it was supposed to, but that afternoon convinced us that hypnosis worked!
Okay, like I said: tame stuff. No zombie slave rays, I didn't become her mindless obedient body slave for the rest of her life. We eventually split up and I haven't (explicitly) played with hypnosis since then. But a man can dream...

j*j
...and thanks to soforia for giving me an excuse to send this.
i must warn you that, by the standards everyone is used to seeing in a.s.s. and a.s.f.s, this will be very tame. it doesn't involve any Mind Control rays or will-weakening spells. it's a true story of an experience i had with hypnosis with my girlfriend.
