Proving to sister that I have a big cock incest story

My sister Cora and I were at it again, arguing and bickering like always. This time, she dared to say something about my package. “Trust me, you and your little willy,” she sneered.

That got me riled up. I’m not one to back down from a challenge, especially when it comes to something as personal as my manhood. “I don’t have a little willy, as you put it, stupid bitch,” I shot back, my voice dripping with anger.

But my sister wasn’t one to be intimidated. “I bet you do,” she laughed, a wicked gleam in her eye. “Says you with the small tits.”

Now, I know what you’re thinking. That’s a low blow, even for siblings as close as we are. But I couldn’t let her get away with that. I decided to prove her wrong right then and there.

“Fine, let’s settle this once and for all,” I said, stripping off my clothes and standing there, proud and naked. My cock was long and limp against my leg, the veins standing out and the head a deep purple.

My sister’s eyes widened as she saw me. “Oh wow, I didn’t realize you were so big,” she stammered, her face red.

“You seen mine now? Show me your tits,” I demanded, my voice husky with desire. My sister hesitated for a moment, then slowly peeled off her top, revealing her small but perky breasts. Her nipples were hard and pink, and I could see the outline of her areolas through her thin bra.

“Satisfied?” she asked, her voice dripping with sarcasm, looking embarrassed.

“Not yet,” I replied while stroking my cock, and it started to stiffen at the sight of her bare chest. I stepped closer to her, my cock now fully erect and pointing straight at her.

“Do you think your tight-shaven fanny can take it, sis?” I asked, my voice dripping with lust. My sister’s eyes widened as she saw the size of my cock. “I don’t know, Tommy,” she stammered, stepping back.

But I wasn’t going to let her back down now. I grabbed her by the waist and pulled her close to me, my cock pressing against her belly. She gasped as she felt the heat of my member against her skin. “I think it can,” I said, my voice low and seductive.

I moved my hips back and forth, grinding my cock against her belly. She moaned as she felt the sensation, her hands grabbing onto my shoulders for support. I moved one hand down to her crotch, feeling the heat of her pussy through her thin leggings. “You’re so wet, Cora,” I whispered, my lips brushing against her ear.

She moaned again as I touched her, her hips grinding against mine. I moved my hand further down, slipping my fingers under the waistband of her leggings. I felt the soft, smooth skin of her inner thighs and then the wet, sticky heat of her pussy. “Oh, Tommy,” she moaned, her head falling back.

I slipped my fingers inside her pussy, feeling the soft, wet flesh of her labia. She gasped as I touched her, her hips bucking against mine. I started to move my fingers in and out of her, feeling the slickness of her juices on my fingers. “Fuck, Cora, you’re so tight,” I groaned, my hips thrusting harder against hers.

She moaned again, her hands grabbing onto my shoulders. I could feel the tension building inside her, her pussy clenching around my fingers. “I’m going to cum, Tommy,” she gasped, her voice breathless.

“Not yet,” I said, pulling my fingers out of her pussy. She whimpered as I pulled away, her pussy feeling empty and wet. I grabbed her by the waist and turned her around, pushing her against the wall. I lifted her leg up, spreading her wide open for me.

I positioned my cock at the entrance of her pussy, feeling the heat of her juices on the tip. I looked down at her, her pussy spread wide open for me. “Fuck, you look so hot like this, Cora,” I groaned, my cock twitching with anticipation.

I pushed inside her, feeling the tightness of her pussy around my cock. She moaned as I entered her, her hands grabbing onto the wall for support. I started to move my hips back and forth, sliding my cock in and out of her. She moaned again, her pussy clenching around my cock.

I started to move faster, my hips slapping against her ass. She moaned louder with each thrust, her pussy getting wetter and wetter. I could feel the tension building inside her, her pussy clenching around my cock. “I’m going to cum, Tommy,” she gasped, her voice breathless.

“Cum for me, Cora,” I groaned, my cock twitching inside her. She moaned again, her pussy clenching around my cock. I could feel the warmth of her juices on my cock, the slickness of her pussy.

“Pound my fanny, Tommy!” Cora screamed as she came, her pussy clenching around my cock in tight spasms. I grunted as I felt her cum, my cock twitching and throbbing inside her. I kept moving my hips, my cock pistoning in and out of her pussy. She moaned again as she felt me still inside her, my cock still hard and thick.

“You like that, don’t you?” I growled, pulling out of her pussy and turning her around. I looked down at her, her face flushed and her eyes glazed with lust. I grabbed her by the waist and lifted her up, wrapping her legs around my hips. I pressed the tip of my cock against her pussy, feeling the slickness of her juices on it. “Say you want my cock inside you,” I demanded, my voice harsh.

“Yes, Tommy, I want your cock inside me,” Cora panted, her hands grabbing onto my shoulders. I smiled as I heard her, then thrust my hips forward, burying my cock deep inside her. She gasped as I entered her, her head falling back against the wall. I started to move my hips back and forth, my cock sliding in and out of her with ease. She moaned again, her hips bucking against mine.

I started to move faster, my cock pounding in and out of her pussy. She moaned louder with each thrust, her hands grabbing onto my shoulders for support. I could feel the tension building inside her again, her pussy clenching around my cock. “You feel so good inside me, Tommy,” she whimpered, her breath hitching.

I kept moving faster, my balls slapping against her ass. I could feel my climax building inside me, the tension coiling in my balls. “I’m going to cum, am going to spunk inside you, UNGH UNGH,” I grunted, my voice strained. Cora moaned again, her hips bucking harder against mine.

I felt pressure flowing fast up my shaft as I continued to shag her harder as spunk spurted out of my cock and filled her pussy. She moaned even louder as she felt my cum, her pussy clenching around my cock in tight spasms. I groaned as I felt her cum, my cock twitching and throbbing inside her. I kept moving my hips, my cock still hard and thick. She moaned again as she felt me still inside her, my cock still hard and thick.

“Oh, Tommy, that was amazing,” Cora panted, her head falling against my chest. I smiled as I heard her, my cock still twitching inside her. I slowly pulled out of her pussy, feeling the slickness of her juices on my cock. She gasped as I pulled out of her, her pussy feeling empty and wet.

“That was so good, sis,” I said, my voice husky with satisfaction. My sister smiled up at me, her eyes glazed with pleasure. “I know, Tommy,” she said, her voice breathless.

We stood there momentarily, our bodies still entwined, our breaths still ragged. Then we pulled apart, our bodies cooling down. “I guess I was wrong about your willy,” Cora said, her voice sheepish.

“And I was wrong about your tits, sure there small, but they’re fucking sexy,” I replied, grinning. We both laughed, the tension between us broken. We got dressed and went back to our day, the argument forgotten. But we both knew that we would be back at it again, our desires still strong.
