"No!" shrieked Jeff, as he pounded on his glass prison's walls. He could feel something happening to his cock and balls. It felt like they were melting and getting stirred up, but them they felt great.
Jake stood and massaged his bulge. Damn, Jeff couldn't help but moan in pleasure. Jake pulled down his underwear. Jeff stared. Jake was huge. No wait. Jeff's junk had merged with Jake's junk. No wonder it was huge.
"Now the fun begin," Jake said. He clapped his hands, and the unbreakable glass cage walls retracted into the ceiling. Jeff lunged for the Chronivac, but fell back on to his bed.
"Oof! What the-?" Jeff gasped as he lay stunned on his bed.
"Oh, I added one of those invisible fences, but it only works on you. I can pass through it without difficulty."
"Why?"
"To see how far you will go to experience an orgasm," Jake said looking down.
"You merged my junk with yours?" Jeff asked licking his lips.
"Our junk, as you call it, needs attention. Now how badly do you want to make me cum? Blow job? Or will you take it up the ass, Jeffy? I set your sex drive at maximum and your inhibitions at minimum, but each person has their own threshold. Surprised you're not slobbering all over it. Well, I see you are drooling. Maybe you can't make up your mind? Heads or tails? I know!"
Actually, Jeff would have been all over Jake's cock, if he wasn't suffering from the paralytic effects of the invisible fence. He couldn't move his limbs. Now Jake was typing again. Ah, yes, movement is returning.
