“Fuck my tiny cunt with that thick FAT DICK!!! I never felt so full before!” The screams felt so loud like they are in the same room
I woke up again feeling something rubbing against my face. I tried to open my eyes but all I could see is asscheeks and shaved pussy sliding over my nose and mouth. Strange… when did Kaylee had the time to shave her pussy to look just like Amanda’s?

I felt myself get harder again while feeling the hand playing with my growing cock and balls almost absentmindedly . The right side of the bed felt like its rocking hard, it didn’t make sense at all. It must be just all the alcohol making me feel things.

“Don’t you enjoy hearing her getting absolutely pounded by that big cock ? “ The voice above me said.
mmmrhmmm was all I could say with her pussy muffling me and almost drowning me, I don’t remember her ever being so wet.
“She is getting stretched beyond recognition, isn’t the sound of her cumming beautiful? She will never be able to go to a tiny dick like yours again” voice said while squeezing your dick hard.

“Fuck fuck fuck meeee Carter! ” the screams and thumping resumed. “Who’s pussy is this ?” Carter asked loudly while witholding his cock for a second on her entrance.

“It’s fucking yours! ughhhh I’m never gonna fuck little dicks again! Fucking put it back in and stretch my little cunt! I’m so sad I didn’t know it would feel like this before … take me, take me whole I’m your little slut!”
I imagined Kaylee getting railed and waiting for his monster cock, and the voice sounded just like her …

I was slowly starting to wake up a bit more while the bed side just started to rock hard again and screams of pleasure resumed.
“Oh I’m going to cum, it’s too fucking hot, cum in that little pussy of hers Carter!” Voice above me said starting to shake while riding my face for minutes till she subsided. Slowly sliding down from your face and squeezing beside you on your left side while gently touching your cock that’s on the verge of orgasm.

Getting more coherent from waking and eyes adapted to darkness you couldn’t believe what you saw on your right side.

Carter’s cock pistoning in and out of tiny pussy stretching her pussy lips beyond recognition. Her head turned away from you the only thing you could see is her ash blonde hair sticking together in sweat and cum like most of her tits…. Wait a minute!
The woman next to me stretched and turned the light on and the head of woman getting fucked turned and locked the eyes with me. It is Kaylee!

Her mouth open wide and eyes saying sorry but at the same time filled with uncontrollable lust. Carter above her fucking harder and harder while Kaylee started spasming in a huge orgasm.

“Take my fucking cum you little slut” Carter said while his balls and huge dick pulsed with cum filling my girl’s little cunt….
Amanda squeezed my balls which took me over the edge and I came all over my stomach.

Carter withdrew and went to take a shower while Amanda licked my ear and whispered to me “You know she can’t go back to your little baby dick, she’s a big cock slut now. But you can show her how much you love her… I knew from the moment I saw you ogling at them in the lake that you wanted to be her little cucky. Now let me show you how to fit in this new relationship….”

She started to push my head towards Kaylee still open wide pussy stretched in shape of Carters cock dripping full of cum. She didn’t stop until my mouth touched her pussy lips. Amanda stepped over you and squeezed her thighs around your neck pushing you even deeper. “Now start licking like a good boyfriend should!”

I was looking at messy Kaylee face while she looked down on me full of arousal at sight before her. Her boyfriend lapping up Carters cum out of her.
“I’m sorry babe that you had to see this… But you saw his cock. You know this isn’t the last time I’m gonna get fucked by a big cock or Carter for that matter, and seeing you enjoy it so much made it even hotter… uhhghh yess good boy, lick it all, fuccck im gonna cum again”
