This is definitely happening

 

Ted liked having his cock tied with rope, and there was the lead that Dave could pull on. Their playing was going fine, and Ted was definitely offering up a hard cock as evidence. But then Dave pulled away a black square of silk and suddenly there was a small guillotine in the room -- and the rope lead was being pulled slowly but firmly toward the blade. An outburst of screams didn't change the master's intense look that began to show a glimmer of a smile only as Ted's cock approached  the device. In a few moments, Dave confidently pushed down on the handle, and the blade separated Ted from his cock. Dave picked up the cock, quickly cinching off the bleeding end so much of its original blood-engorged hardness would remain. Next he ran his lips up and down the shaft while quietly moaning. He knew it was just a hunk of meat, but he also believed that a man's sexual power found its way into the nerve endings of all cocks over the years. Dave had had made a kind of rubber jockstrap with an oversized pouch, and put Ted's cock in it where it could share its energies rubbing up against his own cock. Some days, Dave might have as many as four cocks sharing space with his own. Of course, disconnected cocks stay fresh for only a short period. And the amped-up sexual power Dave was feeling would soon need to be recharged. Dave already had his mind on his next "play partner."
