The four men stripped and neatly folded their clothes. Roy was rock-hard again, and his cock was already dripping pre-cum in anticipation of this next phase of Eric’s training. The other men were in various states of semi-arousal, and provided quite an array of masculine sexuality.

Bob’s lean, tight body was nearly hairless, and he had a thin seven and a half inch cock. Roy had seen each of the men naked during the times they’d gang-banged each other’s slaves, and he always wondered if Bob’s fascination with stretching Jose’s foreskin had anything to do with the fact that the doctor was circumcised. He never bothered to ask, though. Each man had his own turn-ons, and each man had his own unique way of tormenting his slave. Roy was into whipping and brutal fucking; he loved using his monster cock as an implement of torture. Bob, of course, was into stretching limits (and body parts).

Ted was the oldest of the four, and the smallest physically, but he was in great shape. At 46 years old, and standing only 5’8, he still made quite an impressive appearance in the expensive suits he wore to court. The most classically-handsome of the four, he had jet-black hair and green eyes that could go from warm and trust-worthy to cold and merciless in an instant… in other words, a typical lawyer. Standing naked in Roy’s dining room, Ted still made quite an impressive appearance. Though not nearly as muscular as Roy, Ted had almost as little body-fat as the massive cop, and washboard abs that rivaled those of the boy being held captive in the basement. He had a sprinkling of chest-hair curling along his pecs, then a line of hair running down his abs to his pelvis. His cock was the shortest of the four, barely over 6 inches, but it was almost as thick as Roy’s, and despite being the oldest, he was always the first one to get hard again after an orgasm. He was also the last one hard at the end of their gang-bang sessions. Ted could come 5 or 6 times a night if he was really turned on, and his slave’s jaw often ached all night from sucking his master’s thick cock multiple times during an evening. Ted was a master of electrical torture and fist-fucking, and he became even more efficient at those activities once he had a doctor available to tell him just how much he could safely do. He couldn’t wait to introduce Eric to those new sensations.

Mike was 40, and had the natural beefy build of a person who’d worked hard in the construction business for 20 years. He was 6’1, and 210 pounds, with love handles and a bit of a beer gut. He wasn’t handsome, but was so masculine and rugged-looking that he oozed sexuality from his rough, calloused fingers to his worn leather work boots. He had Robert Redford’s coloring… Golden blond hair, and blue eyes, but thick, dark fur covering his chest and forearms. His cock was slightly more than average width, but 9 inches long, and he had huge, low-hanging balls that created an impressive bulge in the skin-tight jeans that he always wore. When he went out to bars, Mike always wore a leather vest with no shirt and a pair of jeans worn down to practically white at the crotch. A black hanky was always dangling from the left rear pocket of his jeans, announcing to anyone that looked at his big, beefy ass that he was a top into heavy S&M. He never had trouble picking up hot young men looking to be a slave to a real, masculine daddy-type, but he’d longed for a slave he could truly make his own. Mike’s slave had undergone the most profound change of them all, but we’ll talk about that later. Right now, the men were ready to head downstairs…

Bob had left Eric bound to the bed. Figuring the kid’s training session would last most of the night, and that nobody would want to stop at any point to let the kid piss, Bob had unwrapped the burlap, then catheterized Eric before he went upstairs, so that his bladder could be emptied at any time, anywhere in the basement. Roy had never done anything like this to the kid, so the catheterization was a whole new experience for Eric. He screamed at the top of his lungs as it invaded his piss-slit. Bob’s cock twitched in his pants as he forced the catheter all the way in, then taped it in place. He then pinched off the tube with an alligator clip on the tip of the boy’s tortured cock. The kid looked so hot, Bob wanted to rape his mouth right then and there. He’d have to wait, though… This was Roy’s slave, and he would be the one to take the boy’s oral cherry. Bob adjusted his stiff cock in his pants, and went to join Roy for their workout and dinner.
