Make a deal with her
From Torg Adventure
Since Kristen and {lastname} are busy, you move over to Meg. You rub her pussy and clit, whispering, "If you help me give my sister the same treatment she gave you, I'll go down on you for two or more orgasms. But I think if we don't work fast, we'll lose her compliance."
She kisses you, then whispers, "Just keep doing what you're doing, while they have their fun. {lastname} gets crazy and frantic with the need to cum again right after the first orgasm. That's when we'll grab her and you can fill her up. If I'm not mistaken, she's close to ovulating." She has apparently had a lot of sex with your sister. It's nice to have an expert on hand.
So you watch {lastname} grind her pussy into Kristen's mouth, moaning and squeezing her tits. Kristen is rubbing your jizz into her clit as lube, muffled groans coming from your sister's puss. You plug Meg's cunt with two fingers, pistoning them inside her.
"Oh, yeah, right there, Kris. Oh, your tongue is amazing. Just like that first time in eighth grade. Mmmmm. Oh, you're going to make me come as hard! Oh, oh, oh, oh fuck! Yes!" {lastname}'s body quivers and shakes as she stops talking and just moans with her mouth set in an 'O'. Kristen must be sucking hard on her clit, because you can see her mouth moving, and your sister’s moans seem to go up and down with her motions.
{lastname} slumps over, holding herself up on her arms, her breath coming in ragged pants. "I want to come again!" she cried.
You and Meg make your move. "Come on, Kristen, help us," Meg says. You and the brunette lift your sister off Kristen, who scuttles out from under her.
"What?!" {lastname} squeals as she comes out of her reverie as you put her down face up.
"More orgasms, just like you wanted!" Kristen moaned, still overwhelmed by her climax.
"We're gonna breed you, just like you bred us," Meg says with sadistic glee. "And with your brother, no less."
Kristen now takes her other leg as you crawl into bed.
"No, wait! I'm not safe!" your sister screams. They spread her legs wide, making her pussy open up, winking at you. She struggles against her captors.
"That didn't matter when you had him fill us with sperm!" Kristen says with an evil grin on her face.
You line up on her pussy and rub your cock up and down, making sure to grind hard into her clit.
"Oh, god, no! Unh! But he's my brother!"
"Oh, do you think we care?" Kristen asked.
After spilling twice in Meg and Kristen, having her friends hold her down is really getting you going. You move your thumb to stimulate her clit. Your sister immediately moans loudly, her body shivering with pleasure. You tuck your fat mushroom head in her very wet slit, and slowly feed it into her slick pussy.
"Oh, my God! Your cock! Oh, God! Your cock! It's in me!" {lastname} cries.
"I'm gonna make you come again and then I'm gonna knock you up," you say, as you squeeze her tits and pinch her nipples. Your sister arches her back and groans as you push farther inside her slippery cunt. You're now penetrating her with half your cock. You pull most of the way out, and then you thrust all the way inside her, balls deep. A shudder travels through {lastname}'s body and a loud moan growls in her throat. You twist her nipples, and her moan travels up the octave until she screams as her body climaxes on your cock. You moan to feel your sister's cunt ripple up and down your shaft, massaging it.
With her coming, you start to hammer her body, thrusting in and out hard and moderately slow. You want to enjoy fucking {lastname} as long as possible. As you pillage your sister's tight slippery cunt, her struggles wane as her body is caught up in lust. As they no longer need to hold your sister down, Meg and Kristen move to suckle each of {lastname}'s tits.
"Oh, {lastname}. You're going to be so beautiful when you're round with my baby in you. The three of you will make a gorgeous knocked up photo op," you say as she writhes on the bed, moaning and grunting as you fuck her.
What now?
