Dave had been drooling over Bob's new stepmom for months. They knew each other like the backs of their hands, so Dave knew that Beth's big titties had also caught Bob's eye. They both enjoyed watching them wiggle as she walked around the house in her skimpy outfits, flirting with her young men, as she called them. There had been more than one occasion when one or both had to excuse themselves to go jack off, usually when they were trying to scheme a plan for the next time Bob's dad was out of town.

Man, your mom is so hot," Dave said as he and Bob were playing video games.

Bob was perturbed by the same old topic his stepmom, Beth, but they had been best buds since grade school, so he cut Dave some slack. "Shut up, dude! And she's not my mom," Bob replied.

"Okay, she's not your mom, but you can't tell me that you wouldn't slip her the sausage if you had the chance.

"I said shut up, man!"

"You said yourself that you've been having dreams about her by the way she struts around here in her mini skirts and bathing suits. Come on, Bob. I bet if you caught her messing around with someone, she'd let you fuck her to keep your mouth shut," Dave said, getting himself hard thinking about being the "someone."

"Fucker! I hate it when you do that!" Bob growled as he walked to his room, trying to hide the bulge in his pants. Dave took the opportunity to rub one out in the bathroom as he fantasized about Beth catching him and giving him a hand. That one worked for Dave every time, and he made it back to the sofa before Bob knew that he was gone.

A few days later, Bob's dad, Gary, said that he was going out of town for a couple of days. "Bob, I want the lawn mowed and raked before I get back so we can go to the cabin this weekend. And before you ask, Yes, Dave can come if he helps you with the yard work."

Gary left early the next day, and the boys put their plan into action. Bob told Beth that he had been called into work but that Dave would come over and take care of the yard work. That way, he wouldn't impede Beth's flirty behavior with Dave. He drove around the block and waited for Dave to call. Dave was supposed to call and leave his phone on so Bob could hear what was happening.

Beth began flirting with Dave the second he showed up. She came out of the house in a yellow bikini, asking Dave if he could help her inside before he started the lawn. "You should really make Bob do his chores himself. He really needs to start carrying his weight around here. Besides, wouldn't you rather be inside with me on such a hot day," she said while toying with the string on her bikini top.

"Um, okay. What would we do if I stayed inside with you?"

"We could do a lot of things, but most of all, you could do me."

Beth tugged hard on the strings of her top, untying it to let her tits come into view.

"You're punking me, right?"

"Come on, Davey boy. You know how this works. While the cat's away, the mice will play. You didn't think I noticed you checking me out every time I walked through the room. I like having you look at me, but we are alone, so no one will ever know," she said as she led him upstairs.

Dave admired Beth's as he followed upstairs and into the master bedroom.

"Sit on the edge of the bed," she stood between his legs as she flaunted her tits. She teased him by keeping her tits just far enough away that he couldn't touch them.

She watched the bulge in his shorts grow erect as she tweaked her nipples. "Take your cock out," she said as she reached for some flavored lube from the nightstand. Beth stroked Dave's cock as she sank to her knees. The warmth of her tongue felt amazing as she swirled it around the head of his penis. "Now, don't you cum too soon," Beth cautioned him as she took his seventeen-year-old cock into her mouth.

The whole time, Bob was listening intently to what his stepmom was doing to his friend. The slurping sounds of his stepmom sucking cock had him so aroused that he couldn't resist the urge to drive back home. Bob decided to park a few houses down so Beth wouldn't hear him pull into the driveway. He snuck into the back door, waiting in silence until he heard the distinct sounds of sex coming from his dad's room.

"You like that, Huh Davey boy?" Bob heard Beth ask his friend. He slipped his shoes off and crept up the stairs as quietly as he could. Peeking over the top step, he could see his stepmom's head bobbing up and down in Dave's lap as his friend's moans echoed through the hall.

Beth slipped her hands under Dave's butt so she could yank his shorts off. "Are you ready for this, sweetie?" Beth asked as she stood and removed her bottoms. She squirted a bit of lube onto the tip of his cock before she climbed on top of him.

Beth grabbed Dave's throbbing dick and started to guide it into her cunt. "Wait." Dave stopped her. "Shouldn't we use a condom?"

"Oh, sweetie. I'm on the pill, so there's no need for that. I'm certainly not going to get pregnant by Gary."

Beth plunged onto Dave's cock, taking him deep in a single blow. She started to hump the high schooler clenching his cock tightly with each stroke. "Remember what I said. Don't you cum too soon and wreck it. You let me know so I can pinch it off and keep you from squirting."

Bob waited until his stepmom started moaning before barging in on them. "What the hell, Beth. Dad goes away, and the first thing you do is fuck my friend," Bob said, trying to sound convincing.

"It would have been you, but you got called into work. You're not mad. You're just jealous that it's not you. Tell you what. Get out of those clothes, and I'll suck you off while I fuck Dave."

"It's gonna take more than a blow-job to keep my mouth shut."

"Come on. Hurry up, and you can fuck me next. I promise."

Bob stripped out of his clothes and climbed onto the bed. "Other side, honey," Beth said when he stood next to her. Bob didn't understand why, but he moved to the other side of them.

Beth sucked Bob's cock into her mouth, rolling it around her mouth as she began to ride his friend. She rode Dave's cock for another five minutes before suggesting that Bob should get a chance to fuck her too.

"No. I want your ass now," Bob said. He grabbed the lube and squirted some on Beth's anus as he pushed her forward. He then climbed into position behind his stepmom. He pressed his cock gently into her sphincter until its head slipped in. Once the tip was in, he scooted closer so he could slam the whole length of his cock up her bum.

Beth began to moan in ecstasy while being pleasured in both holes. Her moans began to increase in intensity and duration, turning to grunts that she was cumming really hard. Suddenly, she began to scream for Bob's dad, Gary.

"Gary, get out here. Oh, God, I'm cumming so fucking hard. Gary, get out of the closet and stick your cock in my mouth.

Bob and Dave looked at each other in wonderment at what she was saying, but then the closet door opened to reveal Bob's dad had been watching through a two-way mirror in the closet door. Gary got onto the bed and knelt where Beth could get his cock into her mouth.

Gary grabbed Beth by the neck as He shoved his cock down Beth's throat, making her go airtight as she took three cocks at once. Gary and the two boys thrust and fucked Beth into oblivion. He would pull his cock out long enough for his wife to gasp in some air before slamming his cock back down her gullet.

"Dave. You've been in her the longest. You go ahead and cum in her whenever you're ready. Bob, hold on a little longer cuz you're next," Gary said as he kept thrusting into Beth's throat.

The feeling of Bob's cock thrusting into Beth's ass was so intense. Dave groaned, "I can't hold it any longer. I'm going to cum!"

"Do it, Dave. Cum in her cunt. Fill her fucking slut hole," Gary growled as Dave pumped his wife full of cum. "Your turn, Bobby boy. Get your cock in there and fill your mother's cunt!"

Bob pulled his cock out of Beth's dumper and shoved it up her cunt even before Dave got his cock out. Beth squealed gleefully at having two cocks in her pussy. Bob grabbed Beth's hips and pounded his cock into her, forcing Dave's whithering cock out at the same time.

Bob and his father watched other's cock slide into Beth's openings as they spit-roasted her. "Go ahead, Bob. Fill her cunt. Cum in your stepmom. I know you want to," Gary said like a man possessed.

Bob slumped forward as he unleashed a barrage of semen into Beth's vagina. "Mommy," he whimpered as he dumped his load into her twat. He'd hoped in vain that no one had heard him, but they all had.

"That's my boy. Fuck your mommy!" Gary laughed.

Gary extracted his cock and stooped to kiss his wife. "Ready, Baby?" he asked as he rolled her onto her back away from the others. Gary got between her legs and slammed his cock into her, and pounded her for all she was worth. "Take it, baby. Take it, you fucking cum slut!"

"Moooore, Daddy," she begged.

"Ahhhh, Fuck, Beth! Here it comes! Ahhh! I'm cummming!" Gary leaned down on top of Beth, sucking her nipples hard while he, too, pumped a load of cum into his wife. Gary flopped onto his back next to Beth as he gasped for air.

"Thanks for the assist, guys," Gary gasped.

"What the fuck, Dad!"

"It's hard to keep up with her in bed, and when we overheard you two talking about her, we thought it would be better than some stranger. Besides, she wants a baby, and with my vasectomy, I can't give her one. If you guys can keep your mouth shut about this, you can keep fucking her until she gets pregnant. It's a fifty-fifty chance that it will have my bloodline.

"What?!" Bob yelled.

"Shut up, Bob. Bob, shut up, and we can keep getting laid. Shut up, Bob," Dave repeated under his breath.

"You guys think you can keep this up all weekend?" Beth asked as she slipped a pillow under her ass and stuck her legs in the air.

"The answer is yes, Bob. Say Yes, Bob. Ya dumb fuck, say yes." Dave whispered again.
