The Tell-Tale Cock

Zack lay on his back, catching his breath, his face glistening with sweat as his mind swam, the images of his imagination fading away in the light. He didn’t even hear Heather’s question, too preoccupied with what he had just done, wondering if he had really just done it. It was one thing that he’d fucked his maybe half-sister, at her request, it was another that he had came inside of her, again at her urging, with the intention of impregnating her, but the massive cherry on top, weighing down everything else was that he had imagined she was his mother. Imagined she was his mother, imaging planting his seed in his mother, his batter filling up her womb just as it currently was in Heather.

He was pulled from the realisation that it had all really happened, or rather dragged, by Heather rolling back atop him, the sudden, unanticipated pressure winding him in his already breathless state. Though it wasn’t all bad, as her naked form settled against him, her mound pressed upon the base of his semi-hard cock, softened from the recent climax but already beginning to stiffen again at the sticky, silky sensation of Heather’s hairless lips on the underside of his cock. With a gasp, he rolled his head towards her and looked in her eyes, catching her curious and determined gaze.

“Where did that come from?” Heather restated, this time confident that she had his attention.

“I-I don’t know what you’re talking about,” Zack said defensively, unsure exactly what Heather meant but not prepared to give anything away.

“Usually blindfolded people are more hesitant and passive, but that was **** and domineering. And that’s not normal. I know because Ashley would have told me if you were an alpha cave man type,” Heather deduced, her eyes twinkling with brilliance. “That leads me to conclude that whatever you were thinking about while blindfolded brought this on.”

“What? No!” Zack half-shouted, a little too quickly, horrified that Heather had put so much together so quickly. “I wasn’t thinking of anything in particular.”

“Oh, come on, you can’t kid me. I know a fantasied induced fuck when I see it,” Heather insisted, leaning over Zack, her face close to his as her large, warm tits squashed against his chest. “Tell me who it was…was it Ashley? Do you miss her already?”

“Uh…” Zack hummed, contemplating saying yes just to end the conversation.

“No, I think it would need to something more to get you so riled up,” Heather pondered, gently grinding herself against Zack’s cock. “Maybe Lisa. Thinking about her in an orange jumpsuit, alone in her cell…maybe fucking her through the bars, Mr. Warden?”

“I…I think you watch too many pornos,” Zack stammered, though somewhat amazed at how quick Heather’s mind could conjure these things up.

“Sure, deflect, that won’t tell me I’m close,” Heather replied with a smirk. “But maybe it’s not about the person. It’s what they represent. Something you want but can’t have. Like Lisa in prison, out of reach, or Chloe, who’s cut you off…or Victoria, the best friend of your ex-girlfriend. Feeling guilty about wanting to move on so quickly? Maybe you didn’t break-up with Ashley because Victoria told you what she’d done with Gavin. Maybe you broke up with Ashley because you realised you might finally have a shot with your old crush?”

“No, that’s not true at all. I couldn’t trust Ashley anymore, and I didn’t constantly want to be looking over my shoulder, wondering where she was and with who,” Zack shot back defiantly, too upset that Heather would think he’d do such a thing to realise he was simply limiting Heather’s options for her. “And how did you know I had a crush on Victoria?”

“It was plain to see to anyone with eyes and half a brain,” Heather remarked, biting her lip. “But I believe you. But I still think I’m on the money with someone you want but can’t have. But maybe it’s even closer than I think.” Zack swallowed hard as she whispered in his ear. “Maybe it’s me.”

“I…I…” Zack couldn’t even get the words out. She was still wrong, of course, but the mere fact that she had moved on to his own flesh and blood made him start to panic.

“I thought I’d have to convince you, but it seems you’ve got more in common with me than I guessed. Must be in the blood that **** just turns us on.” She let out a breath across his jawline as she felt his cock throb against her mound. “Hm, bingo. There’s the reaction I was looking for.”

Zack swore inwardly that his body had betrayed him. But there was still time to do damage control, he decided, as he said, “Y-yes. The thought of fucking you, even though you might be my sister, just made me want to grab you and throw you down and sink my dick in you. So that’s what I did.”

“Yeah?” Heather asked, licking her lips as she rubbed harder against Zack’s hard cock, leaving a trail of juice along his length. “You like the idea of fucking your little sister?”

“L-little sister?” Zack choked, looking down at Heather’s heaving chest, squashed between them. “We’re the same age.”

“You’re older by a month, aren’t you?” Heather teased, as she lifted her ass, pulling her pussy from Zack’s cock and allowing space for his dick to rise and point directly upwards. “Would my big brother like to stick his big cock in his little sister’s little pussy again?”

“Ah, ah” Zack moaned as he was given little choice in the matter; Heather lowering her pussy back onto his cock, this time with the head aiming directly for her hole.

“Ah, ah,” she sighed delightedly, feeling her lips spreading around his bulbous helmet and resting upon her entrance, at the precipitate of slipping in or sliding up between her asscheeks. With gentle **** and pivoting her hips, Zack’s cock pushed inside his half-sister for the second time within the hour. “Aaah, yeeeaasss.”

Zack rolled back his head as he felt Heather impale herself on his cock, enveloping inch after inch in her warm, wet hole until her lips were wrapped snugly around the root of his shaft, just above his balls, her ass resting upon his thighs. Holding him there, tight inside her, she lifted her face to look him in the eye, pausing for a second before lowering her mouth to his, softly, gently kissing him. He was slightly taken aback, expecting another fast-paced, lustful rut like before, but after a moment he kissed her back, feeling guilty about misleading her.

Her tongue snaked out from her mouth, and he opened his lips to accept it as Heather began to move on his cock. She luxuriated over his cock, taking her time raising her hips until his cockhead was just peeking from her hole before sliding back down, all the way down, taking the whole length in one glorious motion. She repeated the motion, continuing to consume his whole cock with her pussy but with increasing speed. She took him faster the second time, her cheeks slapping noisily as they made contact with his thighs again. Again, same motion, a little faster, louder, the bed beginning the creak beneath their union.

Gasping, Zack felt Heather’s mouth leave his and opened his eyes to see the brunette staring back at him, looking curiously at his face while her hips continued to work up and down his cock as if one were acting independently of the other. She plunged herself down on his cock again, filling her hole, and stopped. With both hands on his chest, she raised herself up until she was sitting vertically on his lap, cock still inside.

“It’s not me, is it?” She said simply, not annoyed or accusing.

“W-what?” Zack tried to think, but the beautiful cheerleader sitting on his cock made it difficult. “I just said…”

“I know what you said,” Heather replied, narrowing her eyes. “But you lied. And you’d only lie if you were still trying to hide something…something I was getting close to. Your cock…I felt it move when I mentioned ****, not me.” Heather chuckled as she felt his member twitch inside her once again at the mention of the word. “I don’t think it’s Taylor…and that only leaves…” she smiled as she said the words, “mommy dearest.”

Heather’s eyes bugged from her head as she felt Zack’s cock stiffen inside her again, this time almost feeling as though he had grown another inch in both length and girth, her hole tingling as it stretched to accommodate the new size. His head knocked directly against her cervix, the lewdness of the situation causing it to open slightly, ready to take another load from Zack’s balls, even though it was full to the brim from the last one.

“Yeeeeasss, that’s the ticket,” Heather moaned as she began to ride Zack’s full thickness once again. “While you were fucking me, you were thinking of fucking your own mom.”

“Shit,” Zack growled, raising his hands to cover his face. He dropped them then, to look up at the dark-haired cheerleader now vigorously riding his cock. “You can’t tell anyone.”

“Of course, I won’t tell anyone. In fact,…” Heather laughed as she slammed herself down on his cock. “I just thought of the perfect way to pay you back for knocking me up. I’m going to help you make that fantasy a reality.”

“Noooo,” Zack groaned as he watched Heather’s bouncing tits. “I can’t.”

“Can’t…but you want to, right?” Heather grabbed his hands and brought them up to her breasts, cupping them in his palms.

“Of course, I want to; that’s the problem,” Zack complained, as Heather stroked his forearms while his hands massaged her firm, round tits. “I shouldn’t.”

“Could, would, should; they’re all just words, but when your cock is this hard just thinking about it…” Heather’s eyes rolled back as her head hung over her shoulders, back arching thorough the tremors of a miniature orgasm as she slammed loudly down on his cock again. Regaining her composure, she asked, “Don’t you think your mom deserves to feel this thick, hard cock? To hear how it makes her moan? To feel how deep a son’s love can go?”

“Yes, but-” He began, however, Heather interrupted.

“No buts…” She grabbed his hands from her breasts and brought them to her ass. “…but this butt. Do you want it?”

Against all better judgement, he muttered the word, “yes”.

“Then plant your seed in me, and I will make it so,” Heather made the deal.

Zack sealed the deal with a kiss, gripping tightly onto Heather’s ass so firmly it made her yelp as he pulled himself up, aligning his face with hers. Heather moaned on to his tongue, feeling Zack’s grip on her cheeks pulling her down hard onto his cock while he began to thrust his hips upward, driving himself deeper and harder into her than she had been able to manage by herself. Heather pulled her knees up and wrapped her legs around his waist as her arms hugged his shoulders and neck, her hands reaching up to play with his hair as he properly fucked her, intending to make good on his end of the bargain.

Heather was amazed to see the effect that Zack’s lust for his mother could have on him. Even though she was on top, Zack was the aggressor, ploughing into her so fast and hard, she could do little more than hold onto his body and moan into his mouth. Not surprising though, when she considered how brazen she’d been when she tried to seduce her own father. But when she thought back to the cave, when she and Zack had watched her father and his mother, she thought about how dominated Monica had been. She’d given in to her lust and desire and allowed Robert to take her. Heather couldn’t help but wonder if Zack was picturing himself in that position, not just fucking his mother but taking her, being so wanted that she couldn’t help but give herself to him.

Not that she had much time to think about it, with Zack’s cock driving into her pussy, filling and emptying her only to fill her again rapidly, sending shockwaves of pleasure like a thousand volts ripping through her bones. Her brain tingled along with every other nerve centre in her body, nodes everywhere lighting up with a pure brilliant light until she felt like pure energy. It seeped from her pores and ran down her spine until suddenly, as his cock sank back inside, it was as if he’d flicked a switch and that energy burst forth like a hole in a dam, engulfing her body in torrents of unadulterated pleasure.

Her mouth left his, throwing back her head in a soundless scream, arching her back as the pleasure shot back up her spine. The curvature of her back thrust her tits up into Zack’s face and the young teen immediately wrapped his lips around her nipple. The sudden, new additional sensation sent a second wave of pleasure surging through her nubile teen body, holding his head tight to her chest while his hands continued to pull her ass down against his invading cock, the rhythmic clapping of their bodies echoing thorough out the room like a drumbeat.

“Yes, yeeeaaaasssss,” she moaned, encouraging to suckle harder on her nipple. “Suck on mommy’s tits.”

He groaned into her breast, smothered by her chest and her dark hair covering any light from above allowing Zack to almost pretend that it really was his mother bouncing on his lap, taking his thick cock back where she gave birth to him. The thought made his cock throb as he pushed it deep inside, which, in turn, drew another moan from Heather as she rocked her hips back and forth on his lap.

“Where, oh, fuck, ah,” she began, struggling to form the words amidst her delighted gasps. “Where did you imagine fucking mommy? Did you imagine mommy bent over in the caves?”

“Yes,” Zack admitted, her nipple falling from his lips. “And at home, in my dad’s office, on his desk.”

“Oh naughty,” Heather teased, taking a sharp inhale as Zack crossed to the other breast and took the other nipple in his mouth. “Did-did it make you feel strong to take mommy on daddy’s desk? Did it make you feel like the man of the house?”

“Mmmhmm,” Zack confirmed, muffled from the mouthful of boob.

“Well…you know, the man of house has certain duties he’s responsible for,” Heather said seductively. “How would you like to make mommy’s belly swell with her own grandchild?”

“Fmmmhmmm” Zack moaned deep against her tit, his thrusting becoming more frantic and ****.

“Fuck yes, do it, shoot your seed deep inside me again,” Heather half screamed, almost as loud as the fleshy clap of their writhing bodies. “Oooooh, fuck, just thinking about it is gonna make me cum again too.”

Together, they climaxed. Zack thrust up into her with continued speed and velocity until he felt his cock head open up and spew forth the contents of his balls into her open cervix. Heather’s entire pussy spasmed along with the rest of very other convulsing muscle in her body as one final huge burst of pleasure ripped through her sense. She was only kept from falling from Zack’s ass by his firm grip on her ass.

It was several minutes before they began to slow, their bodies grinding against each other until they felt drained and spent. Zack no longer had the energy to even sit up, his hands falling to his side, releasing Heather’s ass, as he slumped back, supine. Heather, similarly, exhausted and lacking Zack’s hands for balance, followed his body, lying prone atop his chest, as his softening cock slipped from her hole.

“Fuck,” Heather sighed contentedly. “I think that might be enough…until tomorrow?”

“Tomorrow?” Zack picked up on that even in his sleepy state.

“Of course. You have to get me pregnant,” Heather told him, and with a raised eyebrow, added, “You didn’t think that was a one and done kind of deal, did you?”
