Take Nicole up the ass

You hesitate for a moment. This is THE chance to test the serum and her state of mind further. You want to do something audacious, and you haven't had anal sex since college. Linda would never go for something like this. Well, unless you use the serum on her and tell her the same thing you said to Nicole, of course.

You lean in again to kiss the petite blonde, cherishing her taste.

You: "I want to see you naked. Right here, right now. (pause) And then I want to fuck your asshole."

You hold your breath watching her reaction. To your relief, her eyes widen, and her dull smile even grows.

Nicole: "I've never done it like this before."

Nicole flings the blue tank top over her head, revealing a cute pink bra underneath. She bites her lip.

Nicole: "I can't wait to feel you inside me. Inside my ass."

She kisses you again, more eager than before, if that's even possible, while her hands move behind her back, fumbling with the clasp of her bra. As soon as it flies off, she wraps her hands around your neck again. She kisses and licks her way down your neck. You're almost afraid you won't be able to keep up with a young thing like her.

She leans back and pulls down her skirt, together with her panties. You use this moment to adjust the car seats, creating as much space in the back as possible. There is enough room for what you have in mind.

Nicole turns to you, running her hands over her own body.

Nicole: "Do you like me?"

You: "Are you kidding? You're a dream."

Nicole: "No, you are."

Nicole shakes her head in disbelief.

Nicole: "You're the most amazing man I've ever met."

She gets up and crawls in the space between the seats, kneeling on the back seats, looking back at you. You hurry up and open your pants.

Nicole: "I've never felt this way before, Adam. I..."

Your cock springs free, already hard and dripping with pre-cum. Nicole lets out an audible gasp as she looks down.

Nicole: "Is... is it going to hurt?"

You wrap your hand around your erection, stroking it gently.

You: "Now that you mention it..."

You reach over to the passenger seat glove compartment and open it. You can't really look inside from your position, but you feel around for the box. A few months back, Linda had to take some medication that dried out her lips as a side effect, so she used Vaseline at that time to keep them from falling apart. Apparently, it was the only thing that helped. Thankfully, you never got around to throwing the box away. There it is, a cube with rounded edges that fits in your hand, almost forgotten.

You: "We don't need to worry about lubrication, that's for sure."

Nicole (giggles nervously): "That's great! I can't wait to feel you in there."

While you apply the lube, Nicole looks back at you and smiles with flushed cheeks. It's a beautiful sight, and an insane rush of power. Thirty minutes ago, you were a stranger to her, just some dad of her friend, who helped her out in chemistry. Now she kneels naked inside your car, eager to get your dick inside her butt. You are her biggest crush, her ultimate sexual fantasy, her whole world.

You: "There we go. Now, I'm gonna start nice and slow, alright?"

Nicole: "God, yesss!"

Without further ado, you spread her butt cheeks and slowly slide your dick inside her backdoor. Her tightness envelops you, causing you to let out a groan.

You had forgotten how good this feels. You start slow, sliding in and out, getting used to the tighness.

It's clear this isn't her first sexual encounter; her body language shows you that she knows how to act in this context. The way she moans, looks back at you, and moves her body tells you this one isn't as innocent as she looks. One of her hands wraps firmly around your base, stroking in time with the movements of her head, creating a perfect rhythm.

You: "Fuuuuck."

Turning her head, she peers back at you through her eyelashes. Her lips are glistening.

Nicole (huskily): "Do I feel good? I want to feel good for you."

Before you answer, you slide in, taking her deeper. So deep, you can feel her marble ass pressed against you. A loud moan escapes her as you **** your cock further, testing her limits.

You: "I fucking love it. Oh my god!"

One of your hands slips beneath her legs, rubbing her pussy as she resumes moving, finding a new pace that works with this deep penetration.

You close your eyes for a moment, enjoying the feeling and listening to the college girl's moans.

When you reopen them, you see Nicole's turned head, she's panting, her lips slick and parted, pupils blown wide with arousal.

Nicole (gasping): "I can't wait to feel you cum for me. Want you to… fill me up…"

She moves her hips again to take you deeper, her hole still endlessly tight around your glistening cock. Your head starts spinning. It's a good thing she wants you to cum, because you can't possibly hold out much longer. It just feels too good.

You (breathless): "I'm- I'm close..."

Nicole (groans): "YES! Please cum for me!"

Her pace turns relentless, her cheeks smacking against your groin as she takes you impossibly deep, squealing in delight and/or pain. The contractions of her intestines push you dangerously close.

You: "Shit, I'm gonna-"

You can't even finish your sentence. With a final, shuddering groan, you pump your load down her ass, pulse after pulse.

Nicole becomes undone, screeching like an animal as her orgasm hits her.

She holds still, your cock buried deep inside her hole as she milks every last drop from you.

You see stars and, for a moment, feel so light you think you might faint. It's unbelievable! Once you regain full control over your senses again, you pull out - slowly.

She rests her head on her hands, panting heavily. When she turns around again, her blue eyes meet yours. Her cheeks are flushed, her makeup smudged, but her grin is triumphant.

Nicole (breathy giggle): "Wow. That was… amazing!"

She crawls back to her seat, and your hands gently caress her slender body as she does.

You (panting): "It fucking was."

Nicole (softly): "...Wanna do it again?"

You laugh. You can't even stop, the euphoria of the moment catching you off guard. You laugh uncontrollably for half a minute. Once you finally catch your breath again, you look down at the eager blonde.

You: "Later. I... I need a break. But this was... Wow!"

Nicole smiles from ear to ear, preening proudly.

Nicole: "I'm so glad you liked it. I'll do anything for you, Adam. Anything at all."

You stare at her, knowing she means it. And now that your sexual urges are satisfied, your mind is flooded with serious questions. What are you going to do with her now? What are you going to do about Linda and Ashley? Should you keep this a secret or use the Serum on Linda and Ashley? Where the fuck do you go from here?

You peek out the window. The street is still deserted, but that doesn't mean a random person could walk by any second. Clearing your head, you come up with some logical next steps.

You: "Let's get dressed first. This isn't the best place to sit naked in a car, I guess."

Nicole nods, looking slightly disappointed.

Nicole: "Okay."

She bites her lip and crawls out of the space in front of you, and towards the passenger seat. You can smell the arousal from her wet pussy and consider eating her out, before- No, Adam! Focus!

While the two of you are getting dressed, you can't stop smiling, and neither can she.

You: "You were amazing."

Nicole (grins): "You can keep saying that."

You: "I think I will."

Nicole: "So, what do you wanna do next, lover?"

You check your watch. There is still time.

You: "I need you to do me a favor, concerning Ashley."

Nicole raises an eyebrow, then she blinks rapidly.

Nicole: "Oh my god, I'd totally forgotten that you're her stepdad!"

You: "Uh, well, yeah... Is that a problem?"

Nicole puts her hand on your thigh.

Nicole: "Of course not. I don't care about any of that. All I care about is making you happy, Adam."

You see that dreamy smile again, like you're her messiah.

You: "Good. Now, here's the plan..."
