Most men's magazines have surveys that indicate most heterosexual respondents have had one or two homosexual experiences in their life. I had one which I'd like to relate to you, as it stemmed directly from my first heterosexual experience, which I will tell first. I was in a Boy Scout troop with my friend Curtis. We were about to leave for summer camp, and had to get our physical exams. Curtis's mother, a good friend, was a doctor, and agreed to give my a physical. I went to her office one afternoon, a "naive" 15-year-old. His mom greeted me, and we went to an examination room. She closed the door and told me to sit on the examination table. His mom, an attractive divorced woman of around 35, opened my file folder and looked over my records. "Okay, let's get started now, shall we? You'll need to remove your clothes." Since his mother was such a good friend, and had been my doctor for so long,I was not embarrassed or aroused to have her see me naked. It seemed natural,and I was soon nude. His mom seated herself at a chair and engaged me in chit-chat as she looked over my file. Her legs were attractive, and her short skirt rode up high on her thighs as she crossed her legs. She also wore a white doctor's smock. "How have you been feeling?" she asked, and I replied that everything had been fine. "Okay, this exam won't take too long, as I know you're going over to meet Curtis and play some ball this afternoon." His mom had to reach behind her to get a blank form from a shelf, and as she did so, her legs opened, giving me a splendid view of her pussy that was showing through her sheer panties. It caused my cock to stand straight out almost immediately. She turned to ask me something, then noticed my boner and where my gaze was riveted. She said, "Don!" and quickly closed her legs. However, my dick remained at attention. Red-faced, she got out of her chair and brought a thermometer over to me and placed it in my mouth. The air was rather tense, which only added to my embarrassment and arousal. Three minutes later, she took the thermometer out of my mouth and recorded the reading -- it must have been through the roof! My erection remained as stiff as ever. She placed her stethoscope in her ears and came over to me and began to listen to my chest. To avoid looking in her eyes, I look elsewhere, and my eyes fell upon her cleavage. She never wore a bra, which I had known for several years. Curtis and I had always gotten a kick out of our little game of voyeurism, watching through her bedroom window as she changed. I had never seen her naked from the front, but had gotten several views of her luscious ass. As she listened to my chest, and I stared at her tits, I guess she noticed the change. My cock was now throbbing in erection. She removed the stethoscope from her ears and sighed. "Don," she said. "I obviously can't take any decent readings while you're breathing this way." "Well, I'm sorry..." I stammered, and blushed deeply. I wished I could make my hard-on soften. "That's quite all right," she said. She looked down at my boner, then quite suddenly and unexpectedly, she reached out and cradled it in the palm of her hand. My boner surged and throbbed in her hand. "It's quite a nice one for such a young man." My boner, even at age fifteen, had reached a length of seven inches. "We can't get anything done regarding this examination as long as your excitement messes up the readings, so...." and she dropped to her knees,closed her eyes, and began kissing and licking the shaft of my erect cock. She nibbled on the head with her lips, and engulfed my boner in her mouth. This was my first blow job, and I was very excited. I had never experienced an orgasm other than with my own right hand, so the sensations were so new and exceptional that I spurted my cum into her mouth in about thirty seconds. She smiled and said, "That was a good one. Did you enjoy it?" I nodded, and at the same time, we both noticed that my boner had only softened slightly. "My," she said. "I can't believe you're still hard. We'll have to take care of that." She went over and locked the door, then removed her smock. She lifted her skirt and pulled her panties down to her ankles, then stepped out of them. She smiled at me and said, "I know of a way to help you. I'm not going to let you fuck my pussy this time, as I'm having my period. However, there is another way you can fuck me." Being very inexperienced, I had no idea what she was referring to. I was to find out very quickly. Curtis's mother opened a cabinet and got out a jar of Vaseline. She smeared a blob around the head of my cock and the upper part of the shaft. She then got on her hands and knees and I watcher her smooth another blob onto her pink asshole. I was astounded. This was something I had never thought of doing! She walked over to the sink on her knees and washed the Vaseline from her hands. Then she came back over to me and put her head on the ground, her ass waving in the air. She then moaned, "Put it in my asshole, Don. Go slowly, though, because it's not like a pussy." I stammered, "B-but, I've never done it to a girl's...I mean down there. I don't know what to do." She looked back at me with wide eyes. "You're a virgin? Well, Don, later I'll teach you how to do it to my cunt. For right now, what you need to do is gently -- very gently -- push the head of your dick against my butthole until it goes in. Then stop for a couple of seconds until I get used to it. Then I'll tell you what to do." A few minutes later, the head of my cock was inside her ass, and she was ready to continue. She instructed me on the proper method of motion for fucking her ass, and it was not long until I was pumping at her butt and shooting my cum inside her as she finger-fucked her pussy. After I finished, I pulled my wilted dick from her ass, and she got up.She went over to the sink and wet a rag, washing her ass. She rinsed the rag and came over to me where she proceeded to clean me up. "That was very nice, Don. I'd like to continue this again, when we can do it in a real bed. You certainly have a big cock, and you need someone who can teach you how to use it properly." She finished the examination and gave me a kiss on the cheek, squeezing my crotch at the same time. I signed the payment form at the desk and went on over to her house to visit her son, Curtis. Curtis was a year younger than me, but knew more about fucking than I did, as he had fucked two or three of the girls in the neighborhood. He greeted me at the door, and we went up to his room to get some baseball equipment. Curtis started removing his clothes to change into some grubbies that were laying on his bed. He was down to just his shorts when he spoke again.I also had stripped to change into some grubby clothes I kept in his room. "So did you get your examination for summer camp today?" he asked. I didn't answer right away, and my hesitation and blushing must have aroused some suspicion. "What happened at the doctor's office?" he asked, sitting on the bed. I related the story, and when I finished, I noticed that both of us had big erections poking our underwear out. Curtis spoke first. "Wow, I didn't know my mom ever did it any more. You know, she hasn't fucked anyone since the divorce last year." His voice trailed off, and I noticed then that we were staring at the bulge in each other's shorts. Curtis reached over and squeezed my dick through my shorts. I reached over and returned the gesture. He stood up, pulled his shorts down, then pushed me on my back and pulled my shorts down. He sat down again and reached over and began stroking my cock. Not wanting to appear shy, I reached over and began stroking his boner, a shorter one, which was around five inches long. Curtis spoke again. "I've got a better idea. Lie down on the bed." I did,and he crawled over me, positioning his face over my boner and shifting so that his cock and balls were above my face. He began sucking my cock as I played with his balls. Recalling what his mom had done to me, I lifted my head and inserted his stiff boner in my mouth and began tonguing it swiftly. I was rapidly reaching my climax, and just as I was thinking this,Curtis grunted and his cock squirted hot sperm in my mouth. I unloaded my wad into his mouth, and he fell back, panting. "That was really neat," he said. I wasn't too sure a guy could do it with another guy, but now that we know what to do, we can try some other stuff." Still naked, we walked down to the kitchen to get a Coke. A neighbor girl, whom I recognized as a freshman from school, ran through the side yard past the sliding glass doors. We ducked, and she went on by without seeing us naked. After fixing our drinks, we went back up to Curtis's room where we dug out some Penthouse and Hustler magazines and began thumbing through them. Soon we both had hard-ons again. I began absent-mindedly stroking mine while looking at the Hustler Beavers, when Curtis grabbed my hand and stopped me."I've got an idea," he said, and disappeared down the hall. I stood up to follow him when he returned. In his hand he had a jar of Vaseline. "I figure if you could fuck my mom's asshole, we could try it with each other. Why don't you get on your hands and knees and let's see." I dropped to my hands and knees and he placed a blob of Vaseline on my asshole and on his cock. He positioned himself behind me and his cock slid easily into my ass. I thought his mom's blow job and assfuck was fun, but this was just as enjoyable. He pumped and fucked until his cock exploded in my ass. He fell to the floor and said, "Wow! Did I ever cum good that time!" After a couple of minutes of heavy breathing, he got on his hands and knees and said, "Okay, now it's your turn." I proceeded to grease us both up, and soon I was behind him, sliding my hard cock in and out of his butthole. I pumped slowly for about ten minutes as I reached around and stroked his cock, which was hard again. Soon I was reaching another orgasm and suddenly I could feel my cock squirt its load of cum into his butt just as my stroking caused his cock to squirt his cum all over his chest. After I finished, we dazedly made our way to the bathroom and took a shower, soaping each other. Of course, we both ended up getting boners again, but we took turns dropping to our knees and giving each other a blow job before getting out of the shower. We dressed in the grubby clothes and went to the softball field. The girl who had run by the house was there, and Curtis said he would get her to come over the next time we did something like that. He said she would let us fuck her in the cunt. It was about three weeks before he could arrange it, but she was the first girl my own age that I fucked. Since that day, Curtis and I, in addition to dating and fooling around with girls, would manage to blow each other at least every other day, and would do some ass fucking once or twice a week. His mom would let me screw her whenever we were alone together in the house. All in all, my relationship with them went very well, and I was sad when we moved to a different part of town. I never had any other homosexual relationships, and I wouldn't have one if the occasion came up, but it was interesting, enjoyable, and I learned a lot in the process.
