My heart pounded in my chest as the scene unfolded before me. I was hidden behind a bush, watching through the cabin window. It felt like a twisted dream, yet there was no escaping the reality of what was happening.

"Say it again, louder this time," Roy demanded, his voice dripping with arrogance. He lay on the bed with Lisa, still fully clothed in his boxers and t-shirt while my wife was completely naked beside him.

"I want to feel your cock inside my married pussy," Lisa repeated, her voice trembling but somehow more forceful than before. I couldn't understand why she was acting so submissive towards this older stranger who seemed to hold nothing but contempt for both of us.

As I watched, unable to tear my eyes away or take control of the situation, I found myself caught in a web of conflicting emotions. Jealousy gnawed at me, but at the same time, a strange arousal awakened within my deepest desires.

"Good girl," Roy sneered, his condescending tone making my blood boil. "Now let's see how well you can submit to a real man."

Despite my anger, I couldn't help but be entranced by the sight of Lisa's naked body, her black hair cascading down over her shoulders and her curvy figure displayed like an offering to this undeserving man. My mind raced, wondering how far she would go under Roy's influence and feeling both excitement and dread at the prospect.

"Please, Roy," Lisa whimpered, her vulnerability stirring something primal within me. "I need you inside me."

"Ah, such a desperate, little slut," Roy taunted, clearly relishing his power over her. "But first, you'll have to earn it."

The raw intensity of the situation held me captive, even as my thoughts screamed for me to intervene. But as much as I wanted to save my wife from herself and this despicable stranger, I was paralyzed by my own tangled emotions and perverse fascination.

"Are you going to fuck me, Roy?" Lisa asked, her voice thick with need. "I've never been with anyone but Paul."

"Of course, darling," Roy replied, smirking at the mention of my name. "But not before I teach you a few things first."

And as the scene continued to unfold, I found myself unable to look away, caught in a whirlwind of lust, jealousy, and sheer disbelief.

My heart pounded in my chest as I watched the scene unfold before me. Roy was relentless, and Lisa seemed powerless to resist his commanding presence.

"Turn over," he ordered her, a wicked gleam in his eye. As she obeyed, he reached out and smacked her smooth, round ass with a loud crack that echoed through the small cabin. "You want this cock? You're gonna have to beg for it."

"Please, Roy..." Lisa's voice trembled, but there was an undeniable lust in her eyes that sent a jolt through my body. She tried to talk dirty, her face flushed with embarrassment. "I need your big cock inside me... Please fuck me hard."

"First things first," Roy said, grinning maliciously. "If you want my cock, you'll have to suck it."

Lisa hesitated, then admitted softly, "I don't really know how to give a good blowjob."

"Looks like we'll have to change that, won't we?" Roy replied, sitting on the edge of the bed. He ordered her onto her knees, and I could see the nervous anticipation in her eyes as she reached up to pull down his boxers. A moment later, his huge cock sprang free, making her gasp.

"Open your mouth and use your tongue," Roy instructed as she tentatively began pleasuring him. I felt a strange mix of anger and arousal while watching Lisa trying her best to please this stranger with her mouth, learning to give a blowjob under his watchful gaze.

"Use your hand too," Roy commanded, and she complied, stroking him while taking more of him into her mouth. The sight both repulsed and excited me. As she worked, Roy degraded and humiliated her, calling her names and belittling her efforts. And yet Lisa persisted, determined to satisfy him.

Roy said "good girl" whenever she did something right and "bad girl" when she disappointed him. I could see her face reddening under his harsh critique, but at the same time, I could tell she was growing more aroused by the attention.

The humiliation heaped upon her turned me on almost as much as the sight of Roy's huge cock inside her pretty mouth.

"Enough," Roy finally said, pulling her off of him. "On all fours, now."

Lisa obeyed, and Roy smacked her ass again, leaving a red handprint on her creamy skin. "I'm going to fuck you now, Lisa. You've never had anything this big inside you, have you?"

"Never," she admitted, her voice breathy with anticipation. I couldn't believe how much she seemed to want this.

"Good," Roy replied, slapping his cock against her ass as if to emphasize its size. "But first, I think I'll fuck this tight little ass of yours."

"Wh-what?" Lisa stammered, clearly shocked by the turn of events.

"Please, Roy, don't fuck my ass," Lisa begged, her voice trembling with fear. "I've never done that before. It'll hurt too much. Please, just fuck my pussy."

"Fine," Roy said, grabbing a handful of her ass cheek and slapping it hard. "But you're going to need to get used to taking it in the ass if you want to whore yourself out to strangers like this." He spat on her tight asshole, making me clench my fists in anger at the sight. My arousal was undeniable, though, as I watched helplessly from my hiding place.

Roy spat on his cock, coating it in saliva, then slid a finger into Lisa's puckered hole. She cried out in pain but didn't try to stop him. "You're so fucking tight, Lisa. I can't wait to stretch you out."

"God, please be gentle," she whispered, trembling with anticipation. Her submission was driving me mad, but I couldn't look away.

"Relax," Roy said, positioning himself behind her. He pushed the head of his massive cock against her tight entrance, making her whimper. The sight of him trying to enter her sent shivers down my spine, my conflicting emotions warring within me.

"Ow, ow, ow!" Lisa cried out as he attempted to push deeper, but her body wasn't relenting. Roy grunted in frustration, withdrawing his cock momentarily before trying again. Each failed attempt only seemed to spur him on, and I hated that I found it arousing.

"Sorry," Lisa gasped, panting from the effort. "Do you have any lube?"

"No," Roy snapped. "If you're going to be a slut, you should come prepared when you spread your legs for strangers."

"Let me try something," Lisa said, spitting on his cock to add more lubrication. "Maybe if I lower myself onto it, I can control the pain better."

"Go ahead," Roy said, giving her a condescending smirk. "Let's see if you can handle it."

My heart pounded in my chest as I watched Lisa position herself over him, unsure of what would happen next. My wife, Lisa, had completely surrendered herself to Roy, the arrogant older man we'd encountered during our hike.

Unable to look away, I watched as she desperately tried to lubricate her ass with her own saliva. She positioned herself astride Roy, and my breath caught in my throat at the sight of his absurdly large cock juxtaposed against her tiny, vulnerable asshole.

"Come on, you little slut, take it all," Roy growled with a devilish smirk.

I could tell that Lisa was struggling with the pain, but her desire for submission and the thrill of being dominated by this mature stranger seemed to override her discomfort. Each attempt to impale her virgin ass on Roy's thick shaft was met with a stifled moan or whimper, yet she persisted.

"Is that all you got?" Roy taunted her, pinching her nipples and smacking her ass, each strike eliciting another gasp from Lisa. "Your husband must have been a real disappointment if this is what gets you going."

As much as I wanted to intervene, there was something within me that held me back, a perverse curiosity and arousal at witnessing my wife in such a submissive state.

Lisa reached back and spread her asscheeks wide, giving me a view of his big cock pushing against her little asshole. She gasped and moaned as his cock spread her asshole wide. It looked like his cock was about to rip her asshole apart.

My cock was throbbing and hard, looking through the window. I couldn't believe how turned on I was from all this. 

Roy let out a growl as he shoved his cock against my wife's ass. She cried out in pain as his cock almost penetrated her ass.

"No, it hurts! It hurts! It hurts!"

Lisa desperately tried to reposition herself, obviously thinking she could sneak his cock into her pussy instead of her ass. But Roy saw what was happening and quickly tossed her away from him.

"What do you think you're doing?" he spat, his eyes blazing fury. "I'm not here for your pleasure." He roughly grabbed Lisa by the hair and forced her back down on the bed, spanking her bare bottom as she whimpered in pain. "You will learn to obey me."

"I'm so sorry," my wife said. "It's my fault. I did this to myself. I'm such a whore." She got down on the floor, sitting on her ass. Roy stood in front of her, cock pointing towards her mouth again. Lisa opened wide, and he pushes his cock straight down her throat.

"There you go, you little slut," Roy said. "Show me what a pro at sucking cock you are."

My wife gagged on his big cock again. He grabbed her hair and began to fuck her mouth. Lisa kept her mouth wide open as he fucked her mouth. She still had tears in her eyes, but she wasn't resisting. She looked defeated. She reached her hand down and rubbed her little married clit on the floor.

I couldn't believe what I was seeing. Lisa was a strong, independent woman; she wouldn't let anyone else in our marriage boss her around, but for whatever reason, she was submitting to Roy now.

"Oh yeah, that is it," he growled before he yanked his cock out of Lisa's mouth. He made her use her tongue on the tip of his cock.

"Oh yes, you have a talented tongue," he said. "And an obedient tongue."

"You're so big!" my wife said when her mouth was free. "I've never taken a cock this big, ever."

"Now, what do you want, little married girl?" Roy asked. "Since you couldn't take it in the ass?"

"I want you to cum all over me!" Lisa whispered.

I could feel my cock twitch. 

"Then say it again, louder," Roy said.

"Please cum on me, Daddy!" my wife begged. "Please show me what a dirty girl I am!"

"You want to be my slut, little married girl?"

"Please, Daddy, make me your slut!"

"Oh yeah, you're Daddy's good little slut," Roy said. "Get on your knees, little slut."

Lisa got on her knees in front of him, exposing her tiny pussy to him. He made her touch her clit and finger herself while she stared up at him. She was panting, desperate for his cock, but he was in complete control.

"What a little cockwhore you are," he said. "You have no right to deny my cock, you dirty little girl."

"I know Daddy," Lisa said. "I'm a dirty little girl who wants your cock."

"That's a good girl," Roy said. "All you want is to be a whore, isn't it?"

"Yes, yes, yes!" she moaned.

My cock was throbbing, knowing that soon he was going to cum all over my wife's slutty body. I bent down to watch it like a hawk, looking through the window. My cock was aching, so swollen and engorged it hurt.

"Put your mouth on it," Roy commanded.

She immediately took his cock and put it in her mouth, bobbing her head faster and faster every time she went back down. Roy grabbed her by the hair and shoved her face on his cock until his balls were against her lips. I could tell she was struggling to breathe, but she didn't resist, instead taking his big cock deeper than ever before.

Then Roy finally pulled his huge cock out of my wife's mouth and growled "Here I cum, slut!"

I watched in awe as he came, the hot white cum spurting out of his tip and coating my wife's face. She gasped and trembled, almost like she was drowning, as he covered her with his seed.

"You're a dirty little married slut," Roy said, as he stroked his cock and aimed it at her tongue. "Here is my cum, swallow it all."

She eagerly took his cock in her mouth again, sucking out every drop of his cum as he groaned in ecstasy. 

I did the only thing I could do. I pulled my cock out of my pants and started jerking it, cumming hard, cum shooting out of me like a firehose.

When Roy had finished cumming, he wiped off his cock in my wife's hair. My wife was in shock but soon found herself aroused by the sensation of Roy's cum on her body. She looked around, trying to take it all in. She looked so beautiful with semen dripping down her body.

"Now, climb back out that window, and let me sleep!" Roy commanded.

"Yes," my wife whispered. "I'm sorry for bothering you, sir."
