My Dad Married Mandy

In the back seat, Beefcake was still enjoying the blowjob Mandy was giving him.

"Not yet," he said. "Keep driving around some more. I want to fuck her." Mandy let out a moan at this. It sounded like she wanted it too.

I could hear them both laughing and giggling as they re-arranged themselves clumsily on the back seat. I couldn't look as I was changing lanes and trying to get off the freeway, but by the time we had got off, I could hear a loud, rhythmic slapping sound filling the whole car. I looked again, as soon as I could. Beefcake was lying behind Mandy, sort of spooning her, sliding his cock in and out of her pussy with a huge grin on his face. The slapping sound was coming from his balls smacking against her round, tan ass as he fucked her. My own cock was straining against my pants and I really wanted to watch, but another car horn told me I needed to concentrate.

"Oh god!" Mandy kept moaning. "You're so THICK!"

"Fuck yeh!" Beefcake was grunting.

"I'm going to pull over," I said.

"No! Keep driving you little shit!"

I wanted to cry. The car was getting really hot and sweaty and I knew my dad would be pissed if we didn't get home soon. We were close, but I ended up driving around some more so Beefcake and Mandy could keep going.

"Oh god! Don't stop!" she was moaning. "That feels SO good..."

I still couldn't quite believe this was happening. They were barebacking without a condom and I had no idea whether Mandy was on birth control. Maybe she was going to get pregnant? Thankfully though, Beefcake must have decided he didn't want to cum inside her. After another ten minutes or so, he pulled his cock out of her wet pussy and started rubbing it up and down against her smooth, bare ass. Within seconds, he was spewing thick ropes of cum everywhere, all over her legs and her butt. He got a lot on the seats too. It was a really big load.

"Fuckkkkkkkkkk!" he grunted.

When the fucking had finally subsided, Beefcake handed Mandy her panties and shorts to put back on. They were both sweaty and panting and trying to catch their breath. I took us home. The car stank of their sex, and there were large cumshots all over the upholstery. My dad was going to kill me.

When we all got out in the driveway, we must have looked a hell of a mess. Beefcake was sweating and red in the face. Mandy's blonde hair was all messed up and her clothes were rumpled. She had forgotten to put her bra back on, so she quickly stashed it in her bag. My dad didn't seem to notice a thing though. Beefcake smirked broadly as he shook his hand.

"Did you have a good time at the game, son?" my dad asked him.

"Sure," he grinned. "Loser!" I saw him say under his breath.

Mandy said she wanted to take a quick shower before dinner, but my dad said there wasn't time. This meant both Beefcake and I knew she was sitting there at the table with Beefcake's spunk still splattered over her ass and her pussy all juicy and sloppy from their sex. My dad was oblivious to all of this, of course. I don't think he even noticed his wife wasn't wearing a bra. At one point, when she was dishing salad out onto Beefcake's plate I could stare right up her top and see her boobs, nipples and all. Beefcake even ran a hand up her bare leg and squeezed her ass, but she batted him away before my dad could see.

After dinner, we all watched a movie. Since it was an action movie, Mandy excused herself and said she was going to take that shower. Beefcake quickly slipped away too.

"Where are you going?" I asked desperately.

"To take a shit. That okay with you?" he sneered. "What are you, the 'Dump Police'?" My dad laughed at this.

"He's a real good kid that boy," he said to me after he'd left. "You could learn a lot from him you know."

"Yes dad," I said miserably.

15 minutes later Beefcake still hadn't come back so I said I'd go and check to see if he was okay. Unsurprisingly, he wasn't in the bathroom at all. I went up to the first floor and started searching for him. I heard a female moan coming from my dad's room and recognised Mandy's voice. I went down the corridor and opened the door. Inside, Mandy was bent over the dressing table with her shorts and her panties pulled down around her thighs. She was letting Beefcake fuck her again. Both his hands were up inside her top groping her tits.

"Oh shit!" she said, startled, when she saw me standing in the doorway. For a second, she probably thought it was my dad.

"Get out of here you little creep!" Beefcake hissed. "Go and keep your dad busy so we can finish!"

"But..."

"Fucking do it!"

I shut the door on Mandy's moans and the sound of Beefcake's ballsack slapping her ass, and returned to the den. 30 minutes later, Beefcake came down red faced and grinning and said it was probably time for him to be going. He shook my dad's hand again before he left. Behind his back, he mouthed "what a fucking loser" to me.

By this time, my own boner felt like it was about to explode. Beefcake had fucked Mandy twice and I had had nothing. I retreated to my room (which I had to myself for once) and went straight to my video game cupboard. Mandy's gym shorts were still there. They were crusty from all the dried cum on them but they were the best I had, so I put them up to my face and sniffed. All I could smell was Beefcake's dried spunk. It didn't stop me cumming all over them in about two minutes though...

--

I must have jerked off into those shorts another 20 times that week. Every night, I would lie in bed thinking about what I had witnessed, remembering how Beefcake's big juicy dick looked disappearing between Mandy's thighs, and the way she had sucked him off in the back seat of the car as I drove them along. I was ashamed and confused to be turned on by what I had seen, but I couldn't help it.

Mandy swore me to secrecy. She said what had happened had been a huge mistake, and that she wished she could take it back, but that I mustn't tell my dad about it.

"He'd be just as angry at you as he would at me," she said.

At school, Beefcake was cock of the walk. He had told everybody what had happened. A lot of people probably didn't believe him, but of course I knew that everything he said was true.

"When is your dad going away again?" he kept asking me. He said he couldn't wait to come over and get some more of Mandy's pussy.

"Stop it!" I protested. "Mandy says it was a mistake! What happened last weekend can't ever happen again!"

"Yeah?" he grinned evilly. "Want to see what she sent me this morning?"

He took his phone out and showed me a photo. It was Mandy, standing topless in front of the bathroom mirror (the same bathroom she and my dad shared). She was taking a selfie, cupping her bare boobs together with one arm and holding her camera phone with the other. Her face was cut off, but I recognised the bathroom at once. Hell, I recognised her nipples - I'd been thinking about them every night for a week.

"She sent you this?" I croaked.

"Yep," he said proudly.

"But... Why?"

He just shrugged. "I told her I wanted a picture of her tits to jerk off to."

I was silent. I could feel my cock getting hard in my pants.

"Want me to forward it?" he offered smugly.

Burning with shame, I nodded.

My dad didn't have another business trip for a while, but Beefcake was too impatient to wait. He wanted to fuck Mandy again. A few nights later, he told me he was coming over and would be staying the night. He was going to try and get her to have sex with him again, even with my dad in the house!

"No way!" I protested. "He'll bust you! Please don't!"

"Don't be such a pussy!" he said. "I bet you 50 bucks I can bone her again without him realising."

"No. Mandy won't do it. She won't take the risk. Please don't try..."

"Haha, sorry Bitchtits. She wants it man, and I'm gonna give it to her!"

That night, I couldn't let Beefcake out of my sight for fear of what would happen. I was so paranoid that my dad would suspect something. Luckily though, his plan to seduce her didn't seem to work at all. Mandy didn't flirt back with him, even during dinner, and she and my dad went to bed together around midnight. I was majorly relieved. Beefcake was pretty mad of course. He told me it was my fault for cock blocking him all evening. He let all the air out of my air bed to punish me, so I had to sleep on the hard floor basically, but I still went to sleep happy. I was sure I was safe for at least another night.

I was wrong.

About 3 o clock in the morning, something woke me. It was the sound of my bed (as in, my actual bed - the one I wasn't sleeping in), creaking and rocking back and forth right next to where I was lying. Blearily, I opened my eyes in the darkness.

"Oh! Oh! Ohhhhhhh! Ohhhhhhhhhh!"

Mandy's voice was right next me, right by my head. She was moaning. With a mixture of horror and amazement, I realised that Beefcake was fucking her in my bed! They were less than five feet away! I could hear him grunting as he slapped away between her thighs.

"What are you guys doing! You have to stop!" I hissed.

"Go back to sleep moron," I heard Beefcake growl.

"But you'll wake my dad!"

"Fuck off!"

The steady slapping continued, louder than ever.

"Can't you at least go downstairs? He's gonna hear you!!"

"It's more comfortable here."

So they carried on, leaving me to just lie there and listen. I could hear how wet Mandy's pussy was. Pretty soon, my dick started to get hard. Fuck my life, I thought.

"Oh god!" Mandy kept moaning. "You're so good! You're so good!"

My dad was only down the hall. I couldn't even imagine what would happen if he found out about this. He'd go fucking nuclear! Yet I couldn't stop thinking about how horny I was getting listening to Beefcake pleasuring Mandy so good. It was really turning me on. I could hear him talking to her as he fucked her, telling her what a wimp my dad was, and how she should just fuck him from now on. I'm ashamed to say this just made me harder than ever.

There was nothing for it... I reached down into my boxer shorts...

"Stop a second. What's that sound?" Mandy whispered after a while, obviously worried they were about to be discovered. There was a pause as they both listened. Then Beefcake started laughing.

"I think it's Bitchtits!" he sniggered. "It sounds like he's stroking his little salami! Hahahaha."

"Sammy that's gross!" Mandy said.

But I couldn't stop. They both started giggling.

"What a pervert!" Beefcake kept saying. "I told you he wished he could fuck you!"

"Stop it!" Mandy giggled again. "Don't be so mean!"

The truth was I did want to fuck her. I was lying there, choking my meat, imaging it was me, not Beefcake barebacking in my dad's hot young wife's wet pussy. I was so jealous.

"You know he stole a pair of your gym shorts" Beefcake sniggered some more. "He sniffs them every night and thinks about your ass getting all sweaty and shit and beats off to it!"

"Ewww!"

I could tell Beefcake was really getting off humiliating me in front of Mandy like this. His pace was picking up. He had started really pounding her now. It felt like the whole room was shaking.

"It's true isn't it Bitchtits! Say it! Tell her it's true!!"

There was no use fighting it...

"Yes it's true!" I admitted. "I do! I jerk off thinking about you!"

"And?" Beefcake teased. "What about her ass? You think about her ass getting all sweaty and shit, don't you?"

"Yes!" I groaned in defeat.

"You wish you could smell it don't you?"

"Ohhh godddddddd..."

Beefcake started laughing again as I began spurting cum out the end of my dick, all over myself.

"So fast pee wee?" he teased some more. "I'm still going strong up here y'know!"

I had to hand it to him. He really was. It took another ten minutes boning her until he was ready to climax. I could tell it was coming because his strokes were slowing down, becoming more deliberate. Mandy seemed to sense it too.

"You have to pull out! I'm not on anything!" she told him.

"Uh uh!" Beefcake grunted back. "I wanna cum inside you."

Next thing I knew, they were both groaning with pleasure and Beefcake was shooting his load into her! I had to pinch myself to be sure this was really happening.

"Holy shit you cum a lot!" I heard Mandy telling him when he had finally pulled out and rolled off her.

"Plenty more where that came from!" he joked back. I saw him sitting up in the darkness, smirking over the bed at me. "Told you I'd fuck her!" he said.

"You can't tell your dad, okay?" Mandy whispered. "You have to promise Sammy! Our little secret, okay?"

"I guess," I bleated, pathetically. "But please! You have to go now!"

I could see Mandy standing up and start looking for her panties amidst the sheets. She was just wearing the little t shirt she always slept in. I couldn't help looking at her pussy. Beefcake's sperm was streaming out of it. It was running all down her thighs and, by the look of it, down the crack of her ass as well. She was right, he had really plastered her. I wished I knew how to spunk like that. Eventually she slipped out of the room and tip toed back down the hall. I didn't hear the shower running, so I guess she must have gone back to bed with my dad like that - still full of Beefcake's cum.

--

They went on fucking each other in secret for weeks after that. To this day, I don't think my dad ever realised what was going on behind his back. I guess in some ways Beefcake was proved right - my dad was a bit of a dumbass after all.

I continued my descent into the role of pervert and voyeur, jerking off like a crazy man whenever I had the chance to listen to them going at it. I think Beefcake got a real kick out of knowing I was doing that. Even when my dad was away on business, and he and Mandy could fuck in private in the master bedroom, he would make a point of leaving the door open so I could hear exactly what he was doing to her. He loved to make me jealous. He even encouraged Mandy to give me used pairs of her panties to sniff while I jerked off. Mandy said she thought this was gross, but I think secretly she got a thrill out of knowing how obsessed with her I was.

Eventually, Beefcake went away to college. He hasn't come back since. Last I heard, he was doing pretty well on the wrestling team and was banging a lot of cheerleaders. I went to college too, but dropped out after my freshman year. I'm still a complete pervert, and have never been able to get a steady girlfriend. I just have to accept what I am, I guess, and part of me sort of feels grateful to Beefcake for showing me in the first place.
