Sibling talk.

You and Shelly go to your bedroom and casually begin to undress, making conversation as you do.

“Do you think that went well?” You ask her.

“Absolutely. It was a bit awkward, sure, but if we think it’s only going to improve from here, we’ll be alright.” She tells you, removing her shirt.

“By the way, good job on winning Norah over. I was worried for a moment.” You praise.

“Thanks! I was worried, too. We’d spoken before, but we aren’t actually close. I knew she’d have reservations about me in particular. I’m sure you talked her into accepting our relationship.” She removes her skirt, shoes and socks, leaving only her bra and panties. Seeing her half naked, her voluptuous, curvy body right in front of you never gets old.

“I tried my best, but you sealed the deal nicely.” You walk behind her and help her unhook her bra. She finally takes off her panties and turns around, embracing you and kissing you, slipping her tongue inside your mouth lustfully. Her breast press against your naked chest, and your cock forms a tent in your boxers, your last piece of clothing.

“So, little brother? How does it feel to have three girlfriends?” She asks, caressing your dick through the boxers.

“I can’t believe it’s happening. It doesn’t feel real yet.” You admit, taking your hands to fondle Shelly’s big, soft tits. She moans and kisses your neck.

“Even though you’ve already fucked all three of us?” She says with a teasing grin between kisses.

“Have I really? In some ways it feels like a dream.”

“You have. You have three women hungry for your amazing cock, little brother. Of course, that includes me. I want you so much.” She licks your neck and rubs her chest against yours, knowing how much you like it. “I want you to ravage me every single day. And luckily, we have permission.”

It’s true. One of the things you discussed with everyone was what to do with impromptu sex, when the mood was right and you just went and did it with any of the three. Shelly herself raised the question of what would happen if you had sex with her every night since you sleep together. The consensus was that, if it didn’t impede you from satisfying everyone and didn’t have bad consequences on your health, there was no reason to say no. And as you’ve found, your sex drive is so high that you can do it several times a day. You just need to build more stamina.

“I’m all yours now. All you have to do is say the word, and you can have me whenever, wherever, however you want.” She says sultrily.

“However I want?” You grin teasingly. “Even your ass?” You grope her ass, for emphasis.

Shelly gives you a complicated expression. “Not yet. I’ve never done it there.” She admits, though her face lightens up right after. “I did buy a butt-plug the other day, though. I’ll start wearing it tomorrow, okay?”

She leads you to bed, and removes your boxers. She licks your hard cock teasingly and asks.

“So how do you want me, brother?”

“I’m tired, sis. Would you be on top today?” That’s a lie and you both know it.

Shelly grin excitedly. “Of course. Let me take care of you.”

You lay on the bed and Shelly is quick to straddle your hips and lead your cock inside her pussy. She lowers herself on your shaft, holding her breath as she does. When it’s all inside her, she gives a satisfied, ecstatic moan.

“Yeeeess! My brother’s wonderful cock! The cock that enslaved three women! I love it so much!”

“Sis, enslaved is a bit too much…” You say.

“Shush! It’s hotter when I think about it that way!” She frowns angrily at you, but her smile soon returns. “Just lay there, brother. Your loving big sister will make you feel really good.”

Shelly begins to playfully bounce on your cock and you can clearly see it going in and out of her burning pussy. She moans loudly every time it reaches the depths of her tight cunt. She leans back, holding your legs for support and goes even faster.

You can’t help but groan and moan at the pleasure, and Shelly likes it.

“How is it, brother? Does your sister’s pussy feel good? Am I pleasing you?” She gins excitedly as she asks. She knows you’re loving it.

Her bouncing tits over you are mesmerizing. Shelly’s ecstatic face only makes you harder. Her long, blonde hair bounces along with her tits. She makes for an amazing sight. She said she wants you to ravage her every day. Well, good thing you actually want to ravage her every day.

You lift your legs and hips, making shelly yelp as she loses her balance and falls on top of you. You hug her tightly, kiss her passionately and begin to quickly thrust upwards. Shelly’s screams of pleasure are muffled by the kiss.

You explode deep inside her and she is quick to follow. You share the forbidden pleasure of an incestuous orgasm once more, knowing that there are many more to come.

“Not fair.” Shelly says, tired. “I was supposed to take the lead today.”

“I’m sorry. You’re just too hot. I couldn’t help myself.”

Shelly shakes her head and chuckles. She kisses you tenderly, her body still pressed against you from above.

“I love you John. My brother. My boyfriend. My lover. I love you so, so much.”

You fall asleep making out with Shelly, savoring every moment of contact.
