Several years ago I had to undergo some dental surgery. My orthodontist decided that it might be less painful for me if he administered Nitrous Oxide, which is sometimes called 'laughing gas' or 'sweet air'.
Little did I know what might happen when I inhaled the gas. It seems that in the real world some people become 'high' leading to, at times, erotic thoughts and uninhibited behavior even though the person inhaling it is still conscious.
I'm horny 24/7/365.
My orthodontist's female assistant was a beautiful and most desirable young lady who turned me on instantly just from observing her, even though she was wearing her clinical garb which couldn't hide her lovely and tempting body shape. Just looking at her for a moment, even before the mask was put in place for me to breathe the laughing gas, my cock became aroused and stood at attention. She and I exchanged some cordial, innocent, and friendly words before the laughing gas was turned on.
Nitrous Oxide, at least on me that day, worked swiftly.
Through the haze in my mind I heard myself telling her how horny I was and that I hoped she would provide me with some relief. I guess she saw the huge bulge my hard, and by now throbbing cock, was making in my trousers and knew that I was being truthful. I heard her ask my orthodontist if if was OK with him if she jacked me off. He said that it was OK with him if she really wanted to.
I guess she really wanted to, because she did, and I thoroughly enjoyed it. I think my orthodontist did too, because when I shot my hot load he laughed and said he hoped my cum didn't ruin any of his expensive equipment that my cum had splattered on.
