"Hmm," Mark thought to himself, "I'll have to widen the range of the machine to wherever it may be. I just hope it doesn't cause even more problems."
With a sense of urgency, because he was concerned for his friend, Mark set to work, recalibrating the machine. After about ten minutes he was done, he rigged it to go and set it in motion.
Meanwhile, over at the gym, Sean was on the bench press in just Mark's jock. As he raised the bar over and over, the taut muscles Roger had been adoring earlier as Tara flexing against his smooth tan, the jockstrap was pushed into the bottom of his balls as the waistband slowly rode up over his hips. Roger was appalled at what he was going through, and even more appalled at the way he seemed to be hugging Sean's rather large package. Although he felt stretched all over the place it felt as if he had his arms wrapped tightly around Sean's waist and Sean's cock trapped between his legs. Yet he knew he didn't as he could feel the stretched softness of the fabric he'd become against Sean's heaving and sweaty skin. Sean's body odour, which just hours before would have seemed so attractive to Roger now was a stench that pervaded him as he felt he had his cheek on his sweaty balls.
Suddenly, he felt a familiar tingling all over and blacked out briefly. He came to hearing a gasp and loud clang but still felt as if he'd got Sean's cock between his legs and his arms pinned around his waist.
"What the fuck?" Sean gasped.
Roger strained to try to look up to see what had happened...and was surprised he could. He could move his limbs too. He was human again! Then he felt a sense of shock run through him. He actually had his head on Sean's washboard stomach, his arms around his waist and Sean's monster cock between the calves of his legs as he had them curled up under him. Panicking he pulled his arms out from under Sean's now naked body and rolled back off him.
"What the hell's happened?" Sean cried, "how did you get on top of me in here, and where's my jock?"
