Fourteen year old Stan comes home from school early to find his mum fucking their pet dog...

Stan's school boots crunched as he approached his live-aboard canal boat, which was also his home. He left school early, wanting to escape the oppressive classroom atmosphere and get high. Over the years, the boat's vibrant blue color had faded into a grayish shade that blended almost seamlessly with an overcast sky. He was stopped in his tracks as he reached out for the handle of the wheelhouse door. The sound was muffled, erratic and rhythmic, punctuated by moans. He frowned, paused and listened more closely. As he opened the door, the sound became more clear. Now it was clear--his mother, in a guttural and strained voice. Stan's heart pounded, with a mixture of fear and curiosity coursing in his veins. He peered into the cabin and stepped in. It was a surreal sight. The sight that greeted him was surreal. His mother was naked on the ground on all fours. Her body was swaying with the thrusts from their family pitbull. Each time the dog's powerful body hit her, her breasts swung freely. Her face was painted in ecstasy. She had her eyes rolled, mouth open, and cheeks that were a deep red. Stan had never seen her face in such a contorted expression. Her hair was a tangled mess, sticky and damp from sweat. Stan's eyes were glued to this shocking scene. His teenage cock was as fucked-up as he was. His mother groaned with each of the pit bull's rhythmic thrusts. The cabin was filled with the sound of flesh slapping against each other, which bounced off the wood walls. Stan was aware that he needed to leave the cabin, but despite his desire to do so, his body and eyes remained fixed on the scene. The sound of his foot hitting the glass recycling bin echoed throughout the small area, and the world instantly froze. The pit bull stopped mid-thrust. Its ears perked and its head swiveled towards the sound. Stan's mom's eyes opened and met Stan's. Her face was frozen in horror. He said, "Hi, mum," with a voice that was barely audible. She lowered her head, trying to cover her face with hair. But Banjo decided Stan was not a threat, and continued his pounding. She struggled with the dog to remove it. She managed to push the dog away with surprising strength. His massive cock fell out of her body in a wet splat. Stan, what's your purpose here? She gasped as her chest heaved from the effort. She looked at her own breasts, which bounded with each breath, and her skin, which was glistening with sweat. Stan could not help but notice his mother's good body shape. Stan noticed that her stomach was toned and that her legs were firm. He was surprised to find that her clit had been pierced. Her pussy, too, was completely shaved. Stan's gaze shifted from his mother to Banjo who was panting heavy, his tongue dangling out of mouth and his big cock still engorged with his mum's sex juices. She stumbled, her words tinged with desperation as she grabbed her discarded robe. Unfazed, the pit bull licked his own cock while thumping its tail against the floorboards. Does dad know? He didn't understand why he had asked. It was a crazy question. She did not answer his question. Instead, she focused on covering up with a warm blanket. She sat down on the couch and patted the cushion beside her. She said in a trembling voice, "Come on, Stan." Stan walked down the stairs with his eyes fixed on Banjo. The dog stared at Stan, then at his mother, and finally back at him. He looked at him, then back at his mum, and then again. She repeated "Sit Down," her voice now a bit more firm. Stan complied, feeling his legs give way as he sank into the couch cushion beside her. She pulled the blanket up over her lap and tucked it tightly around herself. He began to speak, his voice slightly trembling. What the fuck did that? She muttered, "It's complex," as she tucked behind her ear a hair strand. She took a long breath and appeared to be calming down. You know how people sometimes have... secrets?" Stan nodded as his eyes swept down to the tent inside his pants. As his mother looked at his erection for a fraction of a second, Stan could feel his blood rush to his cheeks. She smiled, a mixture of embarrassment and amusement. Did you enjoy watching Mummy? She asked suddenly, in a tone that was almost playful. Stan's face was hotter than coal in a forge and his throat constricted as he struggled to speak. His mother gently stroked his bulge with her hand. She cooed "It's fine, baby," and said, "You tell me." Her voice was seductive and smoky, in stark contrast to her panic of moments before. Stan stared into her eyes. They were now filled with a hunger that he did not recognize. She leaned in closer. Her breath was warm and sweet. A faint smell of pot that she had smoked mixed with the musky aroma of sex. He could feel the warmth of his skin and her breath just a few whispers away. He managed to shout "Mum" with a hoarse voice. As she began to squeeze her cock into his pants, his protests died in his throat. He was torn, not knowing how to react. His shock and confusion were building inside him. She dropped the blanket she had wrapped around her with a sudden, decisive motion. She was naked and exposed before him as the fabric pooled. Her face was flushed and her eyes were filled with a wildness which both terrified and excited him. Stan stared at the bare breasts of his mother, his eyes drawn to her nipples which stood upright from recent exertion. She said in a low, sultry voice: "Let me show you something." Banjo walked over eagerly to her, tail wagging, after she beckoned him with a crooked-finger. She reached down to stroke the dog’s head while her eyes were fixed on Stan’s. The pitbull licked her neck as soon as he heard the command. His mother leaned into the cushions to allow the dog access. Stan was in a state of disbelief when Banjo's mouth reached her chest and licked her pert nipples. He said "Mum" again, this time with more whine than protest. She whispered "Shh" as she moved her hand from Banjo's face to Stan's cheek. "Just watch, mummy." Katie fell off the couch onto the floor. She was on her knees and faced the pitbull, who stared at her with expectation. She gently stroked the thick cock of Banjo with her hand. Stan's mother bent down and licked the tip of Banjo's knarled penis. She took Banjo's cock in her mouth with a hungry look. The dog let out an obscene whine as his tail beat against the floor. Stan watched as his cock strained against his pants, while his mother's bobbed her head up and down and grew longer and longer. She never looked away, her eyes dripping slightly as she tried to deep-throat the thick shaft. Her eyes were glistening with arousal, and they fluttered shut each time she sucked on the knob of the dog. She would pull back her lips and strings of saliva would connect to Banjo's cock. Then she would slurp back down, making a sound that could be heard throughout the cabin. As he approached the climax, the dog's hips thrust. His movements became more urgent. Stan's cock pulsed in time with the bobbing of his mother's head. She swallowed the clear liquid, her throat clenching around Banjo's head. Stan's thoughts raced. Stan's mind raced. It was his mother on her knees, taking care of their pet as if it were the most natural thing. His body revealed his thoughts, and his hand reached out to free his erection. Mum smiled knowingly when she saw his movements. She released Banjo’s cock and turned towards Stan with her eyes sparkling with excitement. Do you want Mummy to help? She asked with a low, sultry voice. Stan nodded, still with his hand wrapped around his cock. She crawled to him, her breasts bouncing with every movement. Stan gasped as she wrapped her warm hand around Stan's cock. She leaned in, her hot breathe tickling his ears. She murmured "Let me mummy," her voice thick with desire. She did the unthinkable - she leaned down, took his cock in her mouth. Stan's world spun when his mother's mouth engulfed him. He felt her lips gently brushing his sensitive skin as her tongue swung around the head. As she began to bop up and down with her mouth, his eyes rolled in his head. It was an indescribable feeling. His mother, who had held him as a child, kissed away his booboos, was now sucking off like a naughty pornstar. Her fingernails tickled and teasingly rubbed over his sensitive teenage sack. He got goosebumps. As she played with him, each touch set his nerves on fire. He was amazed as she sucked him into her throat and her tongue reached out to lap his balls. He felt her nose nipping at his pubis as she sucked in all of his length with her bulging throat. The saliva dripped from her mouth, mixing with his afin to form a wet, sticky mess around the base of his shaft. Saliva dripped out of her mouth and mixed with his afin to create a sticky, wet mess at the base. Stan was in a trance, watching as Banjo, the family pitbull, moved behind Katy. He mounted her, his powerful back legs straddling her thighs and his furry body pressing into her firm, round buttocks. Katie let out a low groan and pushed away. Stan's eyes were glued to the sight, his hand still on his own cock, and her wet, welcome pussy. Stan was glued to this sight. His hand was still on his cock and his mother's lubricant was lubricating him as he stroked his cock faster and faster. Stan had never witnessed anything so primitive, so raw. And yet, his mother was being fucked. Katie's fingers worked her clit in a blur as her hand frantically moved between her legs. Banjo's thrusts became stronger and his knot grew larger, causing her moans to grow louder. Stan could feel his orgasm growing as she was so close. Banjo's knot stretched Katy wide as it slammed her into the wall. She screamed, her nails digging deep into the couch cushions. Katie shook with such force, that her whole body shook. Her pussy was clenching on the knot, trapping her dog. Stan watched with fascination as the body of his mother spasmed around the animal. She squished her eyes shut, threw back her head, and her chest heaved while she rode her orgasm. Banjo's pumped her seed, filling up her with his hot, slick, dog cum. Stan's hand remained still on his cock, as he sensed his release. The dog was becoming more frantic until, with a final, powerful push, he stopped, his knot growing even larger, and enclosing him within Katie. Stan's orgasm rushed over him with a groan more animalistic than human. He was amazed as he watched ropes of cum shoot out of his cock and arc through the air, landing on his mother's twisted face. She opened her lips to try and catch some, with her eyes closed in ecstasy. Katie's body shook and convulsed as her climax drained the last drops of Banjo's cock. She opened her eyes as her orgasm subsided and stared at Stan with a smear on her cheek. The pitbull tried to pull out but his knot stuck and kept him inside her. Banjo and his mother were caught in a thick knot of fur and skin, their bodies tangled ass to ass. She seemed to get more pleasure every time the pitbull tried to pull her away. A masochistic grin played on her lips. She stared over her shoulder, her eyes filled with lust. She pleaded, her voice strained from exertion. Stan's cock was still spasming after the intense orgasm that he just had. She took a minute to admire the cum ropes that she had used on his chest and stomach. She leaned forward with a sly grin and began to wipe him with her tongue, flicking it out to catch every drop. Stan was in awe of the way his mother's mouth wrapped around his cock and her eyes were locked on his. Her movements were deliberate and slow, as if she was savoring his taste. Her tongue swirled around the tip of the sensitive tip making him shudder. She was slow and deliberate, never taking her eyes off of him, as though she were challenging him to turn away. Katy whispered "This is our secret", her voice a sultry sigh that sent shivers down Stan's spine. She drew back, briefly connecting the two with a cum before snapping them apart. Stan's mind was racing as he nodded. Stan's mother just told him something taboo, incredible and taboo. He was eager to learn more. Katie's voice was full of promise as she murmured: "We can do this whenever you like."
