Yes. You fuck Shelly.

“After that amazing blowjob, it’s only fair.” You tell her.

Your dick is already getting hard again and pressing against Shelly’s stomach, making her giggle. She wastes no time, lifting her hips but keeping her chest pressed against yours. She takes your erection in her hands, moves her panties out of the way and guides it towards her entrance. She rubs the head against her labia a couple of times, looks at Vivian and Norah, who give her tired, consenting smiles. Shelly licks her lips and lowers her hips on top of your cock. You feel yourself penetrating her incredible pussy, and your heads spins from the pleasure.

Since Vivian gave her consent to your relationship with your sister, you’ve been fucking non-stop. In a way, you’d say you know her more than you do Vivian and Norah. The sister with which you had such a terrible relationship as kids in now one of the people closest to you, and you love her with all your heart. You know that Shelly likes to be on top, but that’s because she loves it when you thrust from below, so you do just that. You pound into Shelly’s cunt, and she screams in ecstasy.

“God yes! Fuck me brother! Fuck me hard! Fill my pussy with you marvelous cock!”

The sounds of slapping flesh echo in the room along with Shelly’s loud cries of pleasure. Still a bit tired from her orgasm, Vivian leaves your embrace, positioning herself to have a better view of your cock disappearing into your sister’s cunt.

“How is it, Shelly?” She asks with an excited tone and quick breathing.

“It feels fucking amazing! He’s so good, Vivi! Fuck me more, John!” Shelly lets out, euphoria taking control of her words. “I love his cock!”

Meanwhile, Norah takes advantage that her daughter is too busy watching and moves to monopolize your mouth, slipping her tongue inside it once more. She moans in delight, relishing the simple joy of being connected by your tongues, even as your cock is inside another woman. She then breaks that kiss and offers her breasts to you, cupping them and taking them close to your mouth.

“Remember, my tits are yours to play with as much as you want.” She says with lustful eyes. You immediately take her invitation, groping one and taking the other’s nipple in your mouth, swirling your tongue around it. Her blissful moans are an indication that she loves it.

“Sucking Norah’s tits while pounding my pussy this good…” Shelly whispers with a ragged breath into your ear. “You’re quite the multi-tasker, brother.” She nibbles your earlobe sexily, sending shivers down your spine. “Such a magnificent stud.”

That does it. You stop giving attention to Norah for now, and wrap your arms around Shelly’s waist, pulling her tightly against you. You thrust even harder and faster than before, and you know this was exactly your sister’s aim. She knows the effect her words have on you and has no qualms about talking dirty to get you to shift gears.

“YES! YES! RIGHT THERE BOTHER! DON’T STOP! GIVE IT TO ME! FILL MY PUSSY! CUM INSIDE MEEEEE!!”

You shoot your load in the depths of her pussy. Your body shivers from the pleasure and you feel Shelly doing the same in your embrace. Her body goes limp on top of you, even as you keep pouring more and more semen into her.

“Oh my God, it’s overflowing!” Vivian exclaims excitedly.

“It’s so much… I might actually get pregnant,” Shelly laughs tiredly. “God, I can feel it pouring out of me.” She goes for a kiss, but lets out a surprised yelp and her head jerks back towards her ass. Curious, you look there too and Norah does as well.

“Vivian!?” Shelly exclaims.

Vivian is, without restraint, licking and sucking your cum out of Shelly’s pussy. She doesn’t pay attention to any of you, just keeps licking your sister’s pussy, drinking all the cum she can.

“W-Wait…! Ah! Ah! Mmmh! I’m still too sensitive…!” Shelly protest, but still moans at the sensation.

The sight is enough to revive you cock once more and you know you’re ready for a third round.
