Brad woke up on Saturday morning in what he was beginning to learn was his new normal state. His bedsheets were still wet from what looked to be two separate nocturnal emissions, and his cock was hard and dripping. He had been drinking the energy drinks as directed, and had noticed that his muscles were starting to respond to all the stimulation. He got up and showered, still erect, but was so horned up he felt dizzy. He got it together enough to get dressed and make it over to the club on time, and was happy to be greeted by Chris, Josh and Steve.
The three men helped Brad out of his clothes, and were impressed to see that his cock was hard and dripping precum. Chris gave his dick a tug, and grinned as a squirt of precum was liberated from the thick organ. They walked Brad over to the exam room where a harvesting table was set up and ready to accept Brad's muscular body. The men maneuvered Brad onto the table, connected his meaty nipples to the electrodes, guided his penis into the harvester, and started the sequence. The probe began to enter Brad's cock as before, continued much farther into the man's penis, not stopping until the tick part of the probe was in the middle of Brad's prostate, stopping at the same time the anal stimulator settled into it's position, much deeper in Brad's rectum than before.
Brad felt both probes penetrate him, and as the metal slid deep in his body he felt a wave of overwhelming pleasure and satisfaction. He felt as if he was about to orgasm and about to fall asleep at the same time, and the feelings radiated from his pelvis throughout his bound body, making him almost forget he was nothing more than a naked man bound in a cage of metal. As the electrodes started sending pulses through his nipples and pecs, Brad's body started to shake and convulse in an orgasmic rhythm, but Brad himself started to doze off. The waves of pleasure were too intense, and he mentally and physically turned into a cum machine.
The three men watched the machine take over Brad's body. Brad was smooth except for his trimmed pubes, and the men had no trouble seeing beads of sweat form all over the taught body. They watched as the pecs flexed, the abs rhythmically contracted, the back arched and the muscular quads firmed up and relaxed under the stimulation of the machine. After about five minutes of undulating and moaning, Brad tensed up as the probe in his prostate sucked his load out of him almost instantaneously as it was produced by his sexual glands. All through the stimulation and orgasm, Brad just moaned and muttered nonsense -- he was totally lost in the machine's embrace.
Chris slipped an oxygen canula over Brad's nose, and started an IV to keep Brad's fluids up as the machine continued it's harvesting process. In another ten minutes, Chris could hear the machine extracting another load, and he watched as Brad's body flexed even harder than during the first orgasm. Brad had three more orgasms to go, and Chris knew the man's body would respond more violently as it was pushed beyond it's normal level of semen production. By this point Brad was unaware of even his orgasms -- from personal experience Chris new that the man in the harvester just experienced what felt like a long, half hour orgasm.
Brad ramped up to his third and forth orgasms, and Chris could see that his body was showing the strain of such intense stimulation. Brad's breathing was more like that of a man running a marathon, and sweat was dripping of his flushed and flexing body. As the fifth orgasm approached, Brad's moaning became a yelling, and even a scream has the machine reached it's maximum electrical output. Brad's body was flexing in what might has well have been a full-blown seizure, but the probe in his prostate stayed in place, sucking in his watery final load for processing.
The machine clicked off, and slowly reduced the stimulation level of Brad down to nothing. Chris got Josh and Steve back from the gym, and the three men helped remove the electrodes and probes from Brad's body. As they helped the tired man off the table, Josh noticed that Brad's ass was still flexing. Brad slowly started to come to, but all he could do was ask to be fucked. Chris looked at the other men, and said it sounded like Brad wanted to do a double session -- time to bring Brad into a training room. The men helped Brad into the room, and flopped him face down on the padded floor. Chris started to finger Brad's hole, and sent the two other men to shower and get back so they could start working the desperate boy's ass.
Steve was first back from the showers, and quickly got down on all fours behind Brad's trobbing hole. Steve's pierced cock was fully engorged and dripping, and Chris had a good look at the smooth muscular body as it lined up with Brad and started to slip in -- the only hair on Steve being a lush bush just above his cock. Soon Brad could feel that bush grinding between the firm mounds of his ass, and ass Steve started massaging Brad's prostate from within the boy gave a moan of relief and pleasure. Chris moved behind the pair, and started playing with Steve's ass as Brad's legs spread open, allowing Steve deeper access to Brad's ass.
Josh entered the room, and switched places with Chris. Chris rushed off to the showers as Josh continued forcing Steve's hips deeper into Brad. As Brad's moaning started to turn into screaming, Josh put a finger into Steve, and gave his prostate a tap, sending the man into an intense orgasm, filling Brad's tortured hole with cum. Steve rolled off Brad, and Josh flipped Brad over onto his back. Josh moved between Brad's legs, but before entering him, Josh gave him a deep kiss. Josh had never felt anything quite as good as when Brad snuck up on him after that last orgasm with his girlfriend, and wanted to show the young man a very good time. Brad seemed to come out of the machine-induced delirium briefly, and the two men shared a passionate kiss. The moment didn't last for long, and Josh felt Brad's legs opening up again.
Josh was rock hard, and slid gently but firmly into Brad. He started to undulate in the young man's ass just as Chris entered the room. Chris moved between the coupling men, and started to caress both their bodies as Josh started to pick up steam. Chris paid careful attention to stimulating both men's nipples, then stepped back and activated the implant in Josh's prostate. The implant quickly took over, and Josh felt surges of energy flow from his prostate through his entire body, causing him to shake and drill Brad even harder. The implant started to reach new levels of stimulation, it was so intense that the signals in Josh's cock started to leak into Brad, making the tortured man's ass clamp down on Josh's enhanced penis. Josh felt like he was starting to melt into Brad, and as his orgasm finally hit him the waves of pain and pleasure from the implant drained him to the point of unconsciousness.
Chris pulled the sleeping man off Brad, and noticed that Brad somehow had managed to have one last orgasm during his last fuck with Josh. Concerned that Brad really couldn't take any more, Chris had Steve help Brad and Josh to the showers, and then help Brad go home with Josh. Chris was disappointed he didn't have a chance to enjoy Brad's sweaty body this time, but suspected he and Josh would be back at the club soon enough. With a grin on his face, he walked over across the club and strapped himself onto a table, more than happy to let the machine extract a few loads from him as another implant customer started a training session with a boyfriend. Chris really did enjoy being harvested for gay couples.
Epilogue
In the days that followed, Steve started to make more passes at Josh's girlfriend. Steve really was more straight than gay, and Josh's girlfriend decided she really couldn't get enough of Steve. Eventually they married and settled down in the suburbs of Los Angeles. Josh hardly noticed, as he became more and more infatuated with Brad, and with Chris. After more than a year of producing cum for the club and helping other patrons, the three men devoted their attentions to each other, and formed a household together. They now live in a large home overlooking Monterey bay.
