Alan awoke, struggling to remember. A residual sense of urgency troubled him as his mind cleared. A chill breeze brushed across his face and then, dreadfully, it all returned. Alan sat, restrained, facing the perverse scene. There were two forms, naked, on a twin bed. His younger son, nineteen year old Toby, lay just in front of him. His older son, twenty five year old Felix, loomed over his brother. Felix took Toby's legs and lifted them up and back, bending his younger brother in half. He pushed Toby's knees down until they were pinned to the bed, just under Toby's armpits. His strong grip held the smaller boy in place, with his bare ass exposed. Felix's cock arched up from his fuzzy groin, hard with arousal, and hovered tantalizingly over Toby's pink pucker.
"He likes what he sees," the masked man said from behind Alan. The invader had his arm around front, groping at Alan's crotch. Alan fumed, his wrists straining at the bonds. He was furious at this hellish position in which he had placed his family. His massive debts had come due and he was unable to pay, so his masters had sent this fucked-up stranger into his home as punishment.
Felix had moved away years ago and Toby had headed to college this past fall. Alan was surprised to find himself rather lonely in his empty home. But winter break had just begun and Toby was back home, and Felix had come to visit for the week. With a full heart, Alan was looking forward to spending some quality time with his sons.
But just as the little family was setting down for the night, Alan heard a commotion coming from Toby's room. He poked his head in, only to find his two sons, stripped down to their underwear and hogtied on Toby's bed. Alan glanced around the room, frantically trying to understand what was happening. His son's were writhing and mumbling urgently into their gags. Alan saw that the window was open and the blinds were messed up. Before he could react, a strong arm wrapped around his chest from behind and he felt a needle prick his neck.
"The money was due yesterday, Alan," the stranger said. "I'm here to collect the collateral." Those were the last words Alan heard for a while. He drifted off into unconsciousness.
And now, here in his son's bedroom, the masked stranger was making the brothers engage in outrageous sexual behaviors and Alan was forced to observe everything. This was Alan's punishment for defaulting on his debts.
The invader wore a black domino mask that covered only the area around his eyes. Alan could make out what might be youthful features hidden behind premature aging and a five o'clock shadow. He could imagine that living the rough life of an underworld goon would be tough on both the spirit and body. Despite the man's lined face, Alan believed that this stranger was no older than Felix's twenty five years. His tight shirt and slacks showed that he was quite a bit more powerful than either himself or his sons. Although the man cut a trim figure, the firm curves under his clothes spoke to a well-muscled individual. Alan knew that he and his boys would have no advantage in a physical confrontation.
"Keep going," the stranger called to the brothers.
"Dad?" Felix questioned, looking towards his father with helpless worry in his eyes. He was poised in a position of lust, ready to pounce on his younger prey and grant sexual satisfaction to them both. But this wasn't willing participation. He didn't want to fuck his little brother. The stranger had ordered them to do this foul act, but Felix still hoped it was a bluff. Even then, as both brothers had been stripped naked and their bodies coerced into this repulsive arrangement, Felix still expected his dad to take control and save them all.
But Alan had no choice. "Do it," he said, defeated. The alternatives would be worse.
"But... Dad..." Toby protested weakly. "He's my brother..." Toby was smaller in frame than his older brother. He looked so defenseless there, held tightly under Felix's power, who was in turn beholden to the stranger's wicked desires.
"You have to do it," Alan repeated. "You have to fuck your brother, Felix. Toby, you have to let Felix do it."
Felix turned back to Toby, heart sinking. He gazed down into the frightened kid's face, then down between their long, slender bodies at the place where his hard cock rested along Toby's ass crevice. He rubbed the underside of his cock along the floor of the forbidden valley a few times before pulling back, allowing his cock-head to drag down the cleft. Finally, the older brother's bulbous, swollen knob made direct contact with Toby's winking, rosy bud. His curved pole was already greased up at the stranger's insistence, but the copious precum that seemed to flow freely from his cock-slit might have provided enough lubrication by itself. He wished that he wasn't so hard and that he wasn't so horny, but the pill that the man had given them had really got the boys worked up. Toby, too, was at full-mast, his tool fully engorged and a red knob shiny with pre-cum. Felix's cock drooled another dollop of clear slickness onto his brother's anal ring. Damn, Felix thought, I'm really about to fuck my little brother.
Alan watched, powerless to intervene, as Felix's slim, fit body flexed, adding pressure to the place of forbidden connection. Toby's smaller body jerked when Felix's cock-head slipped past his tight ring. His young face twisted into a mask of pain.
"Push out, Toby," the stranger suggested. "Push out when your brother pushes in. It'll make it so much easier on you. Isn't that right, Dad?"
"Yes, Toby. Listen to him." Alan was so ashamed at being forced to coach his sons on the proper techniques of anal intercourse.
Felix proceeded very carefully, ensuring that any pain that Toby would experience was reduced to mere discomfort. He didn't want to hurt his brother, but he had to keep pushing forward. Toby's body gripped Felix's cock-knob so incredibly tightly, he didn't know how he was going to work his entire shaft into the teenager. After a moment, allowing Toby's virgin hole to adjust, he lowered himself, sinking more of his cock inside. Inch by inch, the hot flesh tunnel stretched open around his girth, accepting his stiffness.
Toby's head was swirling. He continued to push out as instructed, but that only allowed Felix's big rod to enter him more deeply. He didn't want that, but he figured that it would be worse if he resisted. The searing heat he felt when Felix's helmet first slipped inside had faded. Opening himself up to the invading pole did seem to drastically reduce any further agony. He capitulated, giving up any hope that this would stop. Toby accepted big bro into his body. God, Felix was so big. How could he possibly take it all inside? As that impossibly thick meat stabbed deeper, so very slowly filling up Toby's rear channel, there was a strange, gratifying irritation that radiated from that place where the brothers were joined. The smallest embers of a new emotion, a new awareness, were fanned within Toby.
