Mike's sister comes home early

A few minutes later, you hear the sound of the door unlocking followed by the footsteps of somebody walking up the hall. A teenage girl who you recognize as Michael's younger sister Carol appears in the doorway. She's shorter and slimmer than her mother, and unlike her, she looks more or less the same as she did the last time you came over. Her hair is still a dark brown, she's still sporting jeans and a sweater, and she's still wearing rimless glasses.

The reason for this is clear; although you've always found her attractive, due in no small part to her perfectly round butt, her breasts don't look any bigger than a B cup. Looking her up and down, you regret that you won't get the chance to have sex with her...

"Hey, Mike," she says to her brother before turning to you. Her eyes and smile quickly brighten. "John...! You have really good timing...!" she exclaims while walking towards you, throwing her backpack on the floor.

Oh, wait a moment. She doesn't have a boyfriend, does she? And how old was she again? 17? 17 and a half?

Stopping in front of you, she unzips her jeans, stepping out of them as they drop to the floor. You pause the game, throw the controller to Mike, and just sit for a moment, face to face with her bright red panties. It looks as though you'll get your wish after all.

She bends over at the waist, undoing your fly and pulling your pants and underwear down, revealing your cock. She promptly takes it in her mouth, sucking gently with her ass in the air and her hands on your hips. Over on your right, her brother picks up your controller, glancing over at you. "Oh yeah, I forgot to let you know...Carol just turned 18 a few days ago, so I guess you'll be breaking her in," he says, signing you out of the game.

Satisfied with how hard and wet she's made you, Carol lets your cock out of her mouth. "I was wondering when you'd stop by so we could do this," she says as slips her panties off, climbing onto your naked lap. "I asked you to drop by during my birthday party so you could fuck me in front of everyone, remember?"

Your dick twitches at the sound of that, images of the supposed scenario burning vividly in your mind. If only Charles had come to you a bit sooner...

"Uh, sorry about that," you say weakly, finding it difficult to defend your absence for events in an alternate reality that you knew nothing of. "I...was busy. I ran into a bunch of other virgins on the way and...uh..."

"That's perfectly fine," she says with a warm smile, genuinely unbothered. "I understand. I know life's busy for you when you've got to deflower every girl in town, right? All that matters is that you made time for me with your visit today, and I really appreciate that."

Her gentle smile still on her face, she holds your shaft in one hand and the back of your head in the other, drawing you closer as she guides you towards her pussy. "Finally," you hear her whisper before she kisses you deeply. You quickly come to your senses and kiss back, your tongues dancing with one another as your cock slips inside her for the first time. She's soaking wet and impossibly tight, but as you place both hands on her waist, you manage to pull her downwards until your whole length is inside her. She breaks the kiss, gasping and placing her arms around your shoulders. "Finally," she repeats as you slowly begin to fuck her, pulling her down and pushing her away gently.

You reach around her with one hand and grope her bare ass while using the other to tug gently at her sweater. She gets the message and quickly pulls it off and tosses it to the side, revealing a red bra and a pair of perfectly shaped breasts. She isn't the fake, built-to-please toy that her mother has become, but that makes her even more beautiful in her own way. You continue to thrust up into her tight hole, your pace gradually increasing as you unclasp her bra, revealing her hardened nipples. Leaning forward, you take one in your mouth.

"Oh God...John...God, yes, yes...!" she exclaims with feverish passion, throwing her head back and biting her lip as she rides you with more and more enthusiasm. "John!" She jerks forward suddenly, and just like that she's cumming, her whole body stiffening as you rock her gently, sliding her wet lips back and forth on your hard shaft.

"Carol, honey, did you want anything for lunch?"

The sound of April's voice accompanied by her footsteps stalls you for a moment with slight surprise as she enters the living room area. Still nude and coated in cum, she holds a bag of sliced bread in one hand while looking towards you and her daughter. She isn't taken aback or appalled by the scene in front of her in the slightest—if what Carol said was true regarding the arrangements for you to take her virginity at her birthday party, she shouldn't be.

"U-um..." Carol's voice trails off as both your movements slow down to a steady grind. "I...just a sandwich is fine, okay...?"

"Okay, hon!" she says as she begins to turn back into the kitchen. Carol, in turn, redirects her attention to you, but has her movements stopped short once again as her mother reappears.

"Oh, and John!" she adds on with a relaxed smile, briefly leaning past the wall separating the living room and the hallway. "Thanks for taking my daughter's virginity! Too bad about the party, but better late than never, right?"

You hear Carol throw a disgruntled sigh as her mother heads back to the kitchen for good. She looks to you with apologetic eyes. "Uh...sorry about that...Mom can be pretty embarrassing sometimes."

As embarrassing as it may have been for her, your erection was quick to go into double overtime during that—hearing a mother and daughter speak so casually about lunch with one another while one of them is being actively fucked does wonders for your arousal.

"Anyway..." she says slowly as she takes a deep breath and brings herself closer to you once more, her glasses barely managing to stay on her face. "We're not finished here. You made me cum, but I've still gotta get it out of you..."

"How romantic," you hear Mike offhandedly comment with a sneer, teasing her sister as he continues playing his game. You had honestly forgotten he was there—with how quiet he was, it only goes to show how natural this all is for him.

"Chances are we'll only be doing this once," Carol continues, completely ignoring her brother's remark. "So why don't just shoot all of that cum inside of me...?"

That's just what you've been waiting to hear. You pull her close, giving her one final, deep kiss as you stop holding back. You thrust into her once... Twice... And on the third, you erupt viciously, pumping your hot load inside her. She moans, clenching your member tightly and pulling you further in. She holds you tightly as you soften inside of her, kissing you again and again.

You hear a chuckle from beside you. "You're going to have to let him out eventually," says Mike, looking over at his sister's naked body as she presses herself against you.

"Yeah, I guess so," she says, slipping off of your cock and gathering up her clothes. "Thank you, John...that was incredible."

"It really was," you say with a nod and a smile, pulling on your own pants as she gets dressed in the middle of the living room. Looking over her figure, a possibility enters your mind. You're not sure how it would go, but after what just happened between you two, would it hurt to try...?

"Hey, Carol," you speak up, body acting before mind as you haven't really figured out whether to try and go down this path yet.

She looks up to you as she pulls up her pants. "Yeah...?"

Still ruminating about what you really want to say, you find yourself unable to speak. She tilts her head in confusion as she buttons her jeans. "What is it, John?"
