The summer assignment was to construct and demonstrate a helpful robot. Entirely bored by the prospect of assembling a dishwashing robotic maid, I wanted to make a robot to satisfy my libido. I went for the gay robot format and decided to test it on myself. The assignment, of course, was not easy, but I had already made a robot capable of mowing the lawn. All I had to do was construct another robot for a different function, to have sex with. Being I'm a gay scientist it would follow an anatomically correct male robot. I formed this robot out of metallic sculpture to look pleasing to the eye. It's look would be of the athletic build with a chisled face and broad shoulders. I made him look more like a superhero with avocado green skin and a body that looked like it was encased in green tights. He formed no male bulge but when excited a tubular dick would emerge from a hidden door right between his legs. Instead of a belly button I gave him a suctioning hose compartment that could spring out and give an oral massage. The day came when it was ready for testing in my personal assembly shed and I stripped naked in front of him who I call Reamer 1 or R1 unit. When I threw all my clothes off I noticed a slight movement from the strong jaws I wasn't ready for but thought it was my imagination. I reached for the remote to program the unit for the amorous stage. It awakened and walked to me, and smiled with the rubber face I gave it. It took me in it's arms and went through the program of casual courtship I taught it. It held me and began to kiss me on the lips. This felt pleasantly pleasing since I made him two inches higher than me which made him feel more dominant. His hands, programmed for love, reached down behind me and caressed my buns. Then he manually turned me around and his rubber dick appeared out of the compartment and nudged me. With the end of the dick spurted precum lubricant which sprayed me well before he thrust himself to enter without hesitation. With both his hands he bent me over and held me as his dick began the fucking motion. I never felt a round long tubular thing like that being maneuvered by a machine but I heard it groan which I had not programmed it to do, but perhaps picked up with visual tutor. Then it grabbed me around the waist and continued to hump me in strong fashion as if he were enjoying it. All of a sudden I felt like I had no say. The remote was too far to reach and he held me firm in his grip as his masculine sculptured hips were reaming me. Then I heard him speak saying, "yea", & " come on baby." Very unusual. Like a frantic dog in heat his strong legs behind me slapped my bottom. I could feel the contour of the perfectly formed replica of the human dick deep inside me, as this well muscled robotic top was loving every minute of it. Then I realized another problem. This machine would not stop as easily as an ordinary human as it was programmed for lovemaking without premature ejaculation. I tried to reach for the remote but it was too far and he had a solid hold on me. Then, for some reason, I could feel his strong feet spread my feet which made my legs open wide. Soon I was bent over on the workshop table being heavily reamed by a non orgasmic bit of muscular strength. Then he pulled out and then teased me that it was over as he slowly began to reinsert his well oiled tool, and fucked me slow. That throbbing tube felt close enough to be the real thing as it fucked me like a captured dog. His strong muscled legs reaping it's reward, when he pulled out and let out a jet stream. Resting his still hard 8" member on my back, I heard him give a "whew!" We both fell on the couch as he pretended to smoke a cigarette from the lovemaking tutorial. Just when I wasn't expecting it, and right after he said, "that was nice", he said, "let me make it up to you", as the suction oral masturbator sprung from his belly holder to commence giving me a blow job.
