Stepbrother Desire (Erotica)

“It’s okay,” Rachel clarified. “I just… Duncan and I have learned to take our time getting started. I’m surprised that it’s not the same with you.”

“Well, your sister is tighter than everyone else, but she’s not nearly as tight as you are hun,” Duncan said, brushing Rachel’s hair out of her face.

“Really?” Becky asked.

He smiled, nodding. He felt Rachel’s pussy pushing down on him, and noticed a little dribble of her wetness, probably mixed with a little of Paul’s spent seed on the head of his cock. She reached down and wriggled a bit, but then frowned.

“Need me to wet it?” Becky asked.

Rachel frowned again, wriggling around, then nodded, backing up.

Duncan watched, surprised as Becky leaned over and kissed the head of his cock, her soft lips pushing into the dollop of pre-cum lubricant from her sister, and cum from Paul, then sliding her mouth over it and spreading it around. Rachel watched it, then looked up, winking and grinning at Duncan’s surprised expression.

“Y’all are much closer than people know,” he said, smirking.

Becky giggled around his dick, then lifted up as Rachel moved back into place.

“Well, we don’t like weirding anyone out,” the older sister said, “but we’re pretty relaxed and comfortable with each other.”

Rachel nodded. “We’ve had so many threesomes with Mark that it’s kind of stupid to get bent out of shape over some incidental touching.”

Becky giggled, reaching up and brushing Rachel’s hair over her ears.

“Plus, it’s not like we’re eating each other out or anything,” Becky said. “I mean, the most we do is kiss and fondle each other.”

Duncan still found that he really liked the idea and smiled widely at the two. He looked down as he felt a little pressure, Rachel’s pussy back where it was before and pushing down on the head of his cock. She was wriggling downward, trying to force it in.

He winced slightly as it bent at a weird angle, and Rachel stopped, covering her mouth. “Did I hurt you?” she asked, a concerned look on her face and her hands on his chest.

Becky looked up at him as well, concern on her face.

“No,” he said, trying to comfort them. “It just… bent oddly. You’re good to keep going.”

Rachel smiled, but Becky nudged her. “Be careful!” she admonished. “Guys can actually break their dicks, you know.”

The younger sister frowned, and went slower, reaching down and adjusting the two a bit, then gently pressing down.

Duncan felt his cock slide just inside the cusp, and Rachel’s face went tight, then she looked up at him with the same look of quiet alarm that he’d just been describing.

“Fuck that looks so good,” Becky said, scooting down a bit and leaning over to get a better look.

Duncan was again, struck by how incredibly tight Rachel was.

“Oh my fucking God,” Rachel said, wincing and clutching at Duncan as she slowly moved down, centimeter by centimeter. It took the better part of five minutes for her to adjust completely, but she finally got to where she could accommodate his immensity, and was looking at Becky with an almost worried, frantic look.

“Fuck, Becky,” she whimpered, “God, he’s so fucking big.”

Becky smiled, caressing her sister and kissing her cheek.

Rachel groaned, grinding hard against Duncan, who moaned in pleasure as the diminutive blonde’s incredibly powerful vaginal muscles rippled and squeezed on his cock.

“Fucking Christ,” he groaned, his head rolling back.

“You okay?” Becky asked, moving up to her knees and looking at him.

He nodded. “She just flexed her muscles,” he explained.

Rachel moaned, then flexed them again, causing Duncan’s head to drop back to the couch as her powerful cunt flexed and rippled on his iron shaft.Content rights by NôvelDr//ama.Org.

“Holy crap,” he grunted, unable to think of anything clever.

“Jesus,” Becky said, watching the two. He saw her hand moving between her legs, and knew she was masturbating at the show the two were putting on.

Grinding slowly, forcefully, Rachel moved achingly slow down his cock, driving her tight little cunt hard against his shaft, one hand clutching at his chest hair, the other squeezing her sister’s hand.

“Oh my God,” Rachel groaned, her eyes closing and a single tear running down one cheek.

Becky seemed to understand that it was just a tear of happiness, and moved over to hug her sister, sensing how vulnerable she was in that moment.

Again, she ground her vice-like pussy against his steel tower, then flexed her Kegels and sent the two of them swearing and groaning in pleasure.

“Beck,” Rachel whispered, clutching and pulling her big sister close. The sisters stared hard at each other, Rachel’s gyrating thrusts and grinds slowly going faster. Duncan was barely able to watch, the pleasure almost causing him to black out as blood rushed to other parts of his body.

Rachel suddenly shuddered as a rippling motion went up and down her body, yanking Becky up against her and closing her eyes, another tear falling down as the other Murphy girl stroked her hair and whispered sweetly into her ear.

Duncan felt her orgasm hit and forced himself back to reality. Shaking his head and clearing it as he watched, Rachel’s body suddenly quaking as she spasmed uncontrollably on top of him. She seemed to be unable to speak, her body shivering and convulsing as Becky held her tight.

Weakly, she leaned forward, letting Duncan wrap her in his arms and squeeze her gently. “God,” Rachel said weakly. He could feel the incredible orgasm in the punishing contractions on his cock, painfully squeezing down on his girth and making him wince a few times.

“Are you okay?” Becky asked, sweetly caressing the two and moving back and forth between them to make sure they were okay.

Duncan nodded, but was unable able to speak, Rachel’s mind-ripper of an orgasm driving him to the edge. He groaned, shaking his head and pulling Rachel’s face up.

Another tear rolled down, and she smiled weakly, still caught in mid-orgasm. “I’m… sorry,” she whimpered, clutching at him as he leaned in to kiss her.

He shook his head, then gently rolled her on to her back, his cock never leaving her sheath. Slowly, he began to stroke in and out, causing her to groan and clutch at the blanket beneath her.

Becky moved to lift her sister’s head up, sliding it into her lap and stroking her face and hair affectionately.

Knowing he wasn’t going to last long if he kept it up, Duncan winced and stopped.

Rachel took the opportunity to recover, Becky wiping the streaks of tears from her face and checking on her little sister.

“Are you okay, baby?” Rachel asked, reaching out to him. “You can finish if you’re close.”

He shook his head. “Oh no, gorgeous, you’re not done coming. Not by a long shot.”

Rachel whimpered weakly, smiling as another tear worked its way loose and slid down her cheek.

For the next half hour, while Derrek snored and Dana drooled in her sleep, Becky held her sister while Rachel clutched at Duncan and let him fuck her into the floorboards and then through them. After taking a thirty second break to push his orgasm back, Duncan felt renewed and gently started in on the tantalizing young vixen.

Losing count of how many times she got a spaced out look on her face and clutched desperately at him or her sister, Duncan finally felt spent and kissed her a final time before sliding back and lying against one of the couches.

“Jesus,” he whispered weakly.

He lay there, catching his breath, then felt a warm mouth encircle his cock, a diminutive hand sliding around the base and beginning to stroke.

He looked down and saw Becky, her mouth on the head of his cock, pulling it as deep as she could in her small mouth, slurping rudely at the goo that her sister had left and apparently not caring whose it was.

He groaned, then saw some life from Rachel, recovering surprisingly fast. Coming around, she nudged Becky to the left a bit and the sisters both began to pleasure his cock.

He groaned, seeing the two, very-related women taking turns sucking on the fat head of his cock, both staring up at him with very similar faces.

Groaning, he smiled and just enjoyed the taboo nature of what the two were doing, then moaned in pleasure as they both turned their heads and pressed their lips to the sides of his shaft. Moving up and down, they occasionally met at the head and briefly shared a tongue twisting kiss before one would resume sucking and then other kissing the side.

“God,” he groaned, determined to watch as he came. He felt his mountainous orgasm building and practically whimpered in surrender as Becky repeatedly blossomed her lips over the head and hole again and again, Rachel kissing the shaft.

A great spurt of cum burst from the tip and elicited a moan of pleasure from the older sister, causing Rachel to move back up and take the head, gaining the second spurt of cum instead of Becky getting it. The sisters began to pass it back and forth, their mouths full of cum, faces wet with it. Tongues intertwined as the siblings passionately kissed and passed his load back and forth, swallowing some occasionally. Soon Rachel dropped her face back down to suck the head again, and Becky turned to slurp some from her sister’s cheek.

Weakly, Duncan slid to the side and let the siblings clean him and each other up. A few minutes later, he felt them slide up to lay in his arms, pulling a cover over him as they did.

Kelly

The night before…

Seeing the girls that were still up for some fun descending on her husband, Kelly giggled and waved at him, but saw that he’d disappeared beneath a pile of nubile young bodies. She really hoped that he was going to have a good time and wasn’t wanting to stop.

Snickering because she knew the answer to that, she turned and followed the crowd up the stairs. When she got there, she saw people finishing getting dressed, and did the same, pulling on the clothes she’d grabbed on her way out, but tossing her shoes to a nearby couch.
