I wanted to find out what it was like to have sex with another man. I like to look at nude pictures of men but I never actually think of any men I meet in sexual terms or fancy them. So eventually I decided to answer an ad from a man offering what he called « first experience services » . He said my situation was common among curious men. Getting started is the hard part, he said when we made our appointment to meet at his flat. My only rule is that you must do everything I tell you without question. Believe me, I know what I'm doing, he said. Trust me. I was very, very nervous and had to force myself to go through with it. He opened the door wearing a short, light bathrobe and was obviously nude underneath. I was led into the living room where he dropped the robe and told me to undress while he poured drinks. I let my clothes fall and found myself naked with a naked man I'd never met before. Of course I'd been around nude men before in locker rooms and the like but never like this. Relaxed ? he asked. I discovered I was though Id expected to be nervous. He had a pale, muscular body and a small cock that was still flaccid. He reached out and squeezed my cock and told me to do the same to him and I obeyed. Naturally, another guy's cock feels just the same as your own in your hand. That's the hardest part when it's your first time, he said. Now we'll shower. He had a big shower cubicle with a bench seat along one said. He switched the water on and while it sluiced over us, ran his gelled hands all over my body. At the same moment that his fingers found my bum hole, he kissed me, his free hand clasping the back of my head so that I couldn't move free of his mouth. My nudity and his, the sensation of of hot water washing over my naked body, the finger gently probing my anus and his spontaneous insistence immediately overcame any resistance I might have contemplated. I surrendered to his mouth which felt and tasted no different than a woman's. We kissed like that for long minutes, each feeling the hard cock of the other against his belly. Then pulling apart, he forced me down on my knees and thrust his cock into my mouth. It felt huge and I tried to get free of it but his hands clamped my head so hard that I couldn't move it. He began to move his cock in and out rhythmically and I realised that he was using my mouth as if it were a vagina, fucking me in the mouth. I thrust back so that the head of his cock jammed itself deep in my throat with each stroke until at last I felt myself inundated with the burning greasy bitterness of his cum. Afterwards, we lay on his bed while he masturbated me and I him. He kissed me again. Will there be a second lesson ? He asked. I grinned. He turned me over, pulled my buttocks apart and examined my anus. It's pretty tight, he said. We'll have to a bit of work there before you're fuckable. How about same time next week ?
