You take a deep breath and tap your screen, starting the video. Clearing your throat, you look into the camera on the tripod.

“Hey babe… are you enjoying your trip with your friends? Anyways, you might think why is your lovely girlfriend is recording a video in her room completely butt-naked? Well... it’s about our relationships. You, me and… of course my little sister! You always were… afraid? Hesitant? I’m not sure, to be close to my little sister. It’s such a shame. If you had spent more time with her you knew she was special… different…”

You let out a chuckle, then a long lustful groan.

“Oh god yes.. she so is.. I know, I know it doesn’t make sense… It’s best I show you.”

You turn the camera towards me, showing off the enormous bulking figure, clothed in only yoga pants, sitting smugly in a sofa, grinning widely at the camera but remaining silent. You can’t help but let out another lustful moan.

“Mmmm yes… my little sister has been growing up real good! Just look at her! Her biceps are bigger than my thighs! Fuck… compare that to your twigs… the difference is night and day! Just looking at her makes me…” You let out a shuddering moan. “Makes me want to lick and kiss her body all over.”

Not wanting to resist further, you crawl up to me and start kissing me all over, between your mocking taunts.

“Mmm every muscle… Is bigger than your equivalent, her strength tenfold of yours… Mmm.. her biceps… her eight pack… fuck… she’s shredded!”

Grinning at me, not visible to the camera, you slide down to my legs, rubbing my well muscled leg, right next to a certain python.You turn back to the camera, smiling mockingly.

“But what’s this? What’s this enormous bulge running down her right pant leg… it reaches down to her knee!”

You can’t help but laugh.

“Yeah babe... my little sister has a cock… and a monstrous one at that!”

Leaning down, you start sucking and kissing the outline of my cock, occasionally looking up to stare into the camera.

“This enormous bulge, unlike yours, isn’t stuffed! This monstrous girl-cock is just that fucking huge!” Moaning, you turn to me, saying “Fuck… I need it… let me get it out there sis!”

You pull down my yoga pants with fervor, only to have my cock spring out and slap you across the face with a loud fleshy slap, leaving a red mark on your cheek.

“Ouch!” You laugh. “Sis, be careful! Your cock is deadly weapon! It’s far bigger than my boyfriend’s little worm…”

You hold my cock and let in hang, putting her face up against it.

“Oh see babe, see how her SOFT cock dangles over my face. Marking it with its sweat and musk. Drooling its thick pre-cum down my back. Yeah… I thought you had to see this… it was the only way to show you that when you finally do get back that things are different now.”

You look up at me, giving me a loving and lustful smile, then turned to the camera.

“I’ve been claimed by this bull… this shebull.”

You begin to kiss my cock, the wet smacks loud and clear against my long veiny meat.

“She’s turned every single night into a theatre of pure pleasure for me, making me scream in ways you never did. Fuck… You only made me moan… she made me scream my guts out, making our neighbours call the cops on us. Guess the face they had when the cops realized that it was this monster of a cock that made me scream…”

You take my cock and start to slap yourself with it, the wet saliva left from your own mouth sticking and leaving strands between the cock and your cheek.

“Fuck… just look at this cock… not even hard and already over a foot long. It’s been stretching my pussy, I don’t think I would even feel you anymore.”

You can’t help but scoff and give a dead stare to the camera.

“Not that you will get the chance…”

You start to lick, suck, and kiss my cock throughout your talking.

“You see, she’s an Alpha… a true bull. And like one she’s claimed ALL my holes. Just be reasonable honey… you will never measure up to her godly size. She’s bigger, better and stronger than you. Besides that…”

At that, I took your hair and pull you onto my hardened cock, grinning. You look up at me, eyes wide for the camera.

“Oh sis I’m not don…”

The sound of your talking was quickly replaced by loud gagging and choking noses as I decided to skullfuck you for a bit. After a delicious bit of oral, I pull you off my cock. Your mouth makes the loud vacuum pop, followed by a slap from my cock and loud gasping. You try to recover, breathing deeply.

“Fuck… fuck… sis... you can’t… just…” I slap you with my cock, the pre flinging onto the ground. “Ah… yes… yes… goddess... let me just suck on your huge nuts…” You latch onto my fitting bull balls, moaning, “Oh god yes… I’m your little cumslave, yes I am!”

You start to worship properly, moaning, kissing, and sucking.

“Your balls are just so huge! I can’t even fit one in my mouth! Oh and they stink too… just all your shebull musk just running through my nose…. Fuck it’s making woozy!”

I decide that enough is enough and force my cock down your throat again.

“Mmmm I… GLLKk!” The worshipping words are replaced by gagging and choking, going on for a bit, sometimes gasping and some swearing. I push in very deep, my cock visible through your neck, and start to cum, filling you up with ease. You start to gulp exaggeratedly, sucking down my shebull cum.

“Mhmmmm!” There is a loud pop as I pull you off my cock, followed by gasping and gulping. “Oh my… sis… you STUD! Fuck…”

You turn to the camera, rubbing your stomach with glee.

“You see my belly babe... My little sister just shot…” You take a moment to gasp, “easily a gallon, if not several, of cum down my throat… just look at my belly… its completely swollen! That’s a big difference to your little trinkle, isn’t it honey…”

Giggling, you hug your belly and shake it gently from side to side, the sloshing of my thick cum audible. You look up at me then smile at the camera.

“Just think about how much cum she has pumped away in me. She flooded my pussy so many times I must be pregnant by now… her virile shebull sperm would probably eat the birth control for breakfast… I’m her new mate.”

Smiling sweetly and mockingly to the camera, you wave at the camera.

“Goodbye now babe. Hope you have a lot of fun on your trip. My little sister and I are going to get serious now.”

Giggling, you get up, walking over to the camera, making sure your stomach was in the frame the whole time, sloshing away. Once you cut the recording, you bound over to me, throwing yourself into my lap. I wrap my arms around you as you do what you can to imitate. Leaning my head down, I whisper into your ear.

“Are you happy now?”

Looking into my eyes, your own sparkle with mischief and lust.

“More than ever.”
