You try to apologize to your brother, but it doesn't go as planned

An hour or so later, you stagger back into your apartment to face the music, feeling rather like a dead woman walking. You're kind of shocked your Dad isn't blowing up your phone already telling you how disgusted and disappointed he is. Part of you wouldn't even be surprised if the police were waiting to put you in handcuffs and drag you away. Sure, Nick is overage, but....you still took advantage of him, took advantage of your sweet, innocent baby brother in the worst way possible. Only, the apartment is quiet as you slide the door shut and slip off your shoes. You just hope Nick hasn't gotten rightfully spooked and run off somewhere for fear that you'd just jump on him again like last night. You need to talk to him, need to try and apologize at least.

You shuffle into your living room with a hoarse sigh, then promptly freeze in utter shock at what's waiting for you there. Nick is on all fours, cleaning up some of the pizza crumbs his grungy friends left last night with a brush and pan. Normally that would be a welcome sight, but he's also still totally naked! His cute round butt is up in the air towards you, wiggling quite adorably from side to side as he works. Just like that, your massive cock stirs between your legs. You bite your lip, hard, as your suddenly hungry gaze drifts over those two smooth, pale cheeks, your mind boiling over with memories of how it felt to spank, squeeze and fuck your baby brother's girly bottom.

It's a close thing...and you feel yourself teetering on the edge of ripping down your pants and just shoving your iron-hard erection back into that soft, tender hole, but the sickening regret you still feel holds you back. Why the fuck is he still naked? He's not covered in your dried cum anymore, so he must have washed himself. Why didn't he get dressed as well? You're breathing hard, feeling your cock press tightly against your pants once more. Nick must have heard something, because he lets out a rather girly squeak of shock and hurriedly turns. His big grey eyes find you, and he smiles widely, an utterly adorable blush coloring his pale cheeks. Hold on...smiling? He's not...disgusted with you, even after what you did?

"Hey...um, Lucy." He wriggles up off the floor, standing there with his arms by his sides, totally bare and exposed like he doesn't even know what that does to you. Your lust-filled eyes drift over his cute chest and pink nipples, then down his soft belly. His pale thighs, so smooth and round, draw your hot stare, the tiny dickie between his legs even cuter now it's all limp over his little balls. "Hehe.." He giggles, preening under your hungry glare. "When I woke up you were gone, so I thought I'd surprise you by cleaning up the mess I made...like this. Do you like it?"

"Nick" You growl his name, your voice thick with lust. Somehow you're holding yourself back from pouncing on him, drawing on reserves of willpower you didn't know you had. Reserves you wish you'd somehow found last night instead. An average New Female's sex drive is utterly vicious when roused, yours even more so, and your entire body feels like it's burning up with the urge to **** him to his knees and shove your hard cock back where it belongs down his throat. "We need to talk...can you get dressed please?"

"Okay." He nods, lips curling into a disappointed pout. Still, he meekly obeys in a way you'd have once thought he'd never do for you again, scurrying off towards your bedroom and giving you another welcome glimpse of his cute, jiggling butt. You're biting your lip so hard you can taste blood as you waddle awkwardly over to the couch and sit down, your throbbing cock pressing against your leg. The living room...isn't entirely clean, but Nick's still made a good attempt at it while you were gone, gathering up the rubbish his trashy guests left. Now...if only it were that easy to toss out what you did to him as well, bury it somewhere deep where you never have to think of it again, but you're going to try all the same.

Nick returns a couple minutes later, wearing a thin t-shirt, a pair of tight little briefs and nothing else. For a moment you just gawp at him again, admiring the way the filmy fabric of his underwear clings to the cheeks of his adorable butt. There's a vague snapping noise from between your legs as your straining erection rips its way through another pair of panties and presses against your trousers. Fuck...he's almost more tempting like this. Why isn't he wearing bottoms? You want to snap at him to dress himself properly, but the way he's gazing back at you with those huge, grey eyes and adorable little smile you find you can't.

"Sit down please, Nick." You pat the couch next to you with a trembling hand instead. Fuck, you'll just have to deal with him this way. At least he's not entirely naked anymore, right?

"Not...in your lap?" He giggles, wiggling his butt from side to side. The thought of those plump cheeks bouncing on top your straining erection makes you moan hoarsely, but you can't.

"No." You growl, the edge of boiling lust in your voice sounding almost feral. Fuck...control, Lucy, control. You're starting to feel like this was all a mistake and you should have just texted him to leave before you even got home, but you can't stop now. You have to apologize! With a little nod and hot blush, Nick darts over to the couch and plants his plump butt down right next to you, close enough his soft, bare leg brushes against your own. He turns to look expectantly at you, pretty fixed on your face. There's not a trace of the fear or anger you were expecting to see on his face, instead he just stares at you with trust and...love. "I need to..." You begin, your voice breaking as another wave of sickening regret sweeps through your body. How could you have done this to him? Your own baby brother... "I...have to...I'm sorry, Nick. I'm so, so sorry." He pauses, biting his lip in obvious surprise.

"For...what, Lucy?" He asks. You let out a strangled gasp...isn't it obvious? "Oh, you mean...um, spanking me like that." He giggles again, the silvery sound tingling in your eyes like birdsong. "It's fine. I really um...deserved that. Actually, I was kind of thinking...it was pretty hot." His lashes flutter, his adorable blush darkening as your stare open-mouthed at his pretty face. "Not at the time, but thinking about it now I um really, really like the idea, how you just took control like that and punished me. If I'm ever naughty or maybe if you just want to, you can...do that again." He's breathing a little harder, his butt wiggling on the couch beside you.

"What the fuck?" You stammer helplessly. Not only is your baby brother apparently not at all upset that you took advantage of him, now...he's telling you he liked being spanked! Of course you loved spanking him too, but that was supposed to be a punishment for him!

"And of course...what you did afterwards was even better!" He continues happily, hardly seeming to notice how stunned you are. "I never knew your cock was that huge. I mean, I knew New Females had big ones, but yours is just massive, bigger than the New Female pornstars even, and I love it so much! When you shoved it in my mouth, and after, sucking your balls like that, it felt so amazing. You've got to do that to me again. And I've never cum before like I did when you were fucking my butt! It just felt so good, way better than using my own dick! In fact...I was kind of hoping we could do that again, right now, if you want to, Lucy?" He leans into your shoulder, breathing hard and you suddenly notice the little bulge tenting the front of his tight, tight briefs. Fuck...he wants you to fuck him! Right now!

"Stop, Nick...I can't!" You gasp out somehow through the haze of desire, a little shocked you even found the strength not to just give in.

"Why not?" He asks, frowning slightly. "You were happy to last night!"

"You're my brother, my little brother!" You stammer, tears suddenly stinging in your eyes. The silly boy finally seems to notice how tightly wound you are and lets out a shocked little gasp. "It was a mistake. The worst mistake I've ever made! I never should have done that to you! I'm sorry, Nick!" A few tears drip down your cheeks as he stares at you open-mouthed.

"Lucy I...." He swallows, his pale throat tensing. "I...no, it wasn't a mistake!" He shakes his head with a firm pout, his usual stubbornness returning at the worst possible time! "I've wanted you to do that for ages! I promise, for over a year now, it's all I've thought about." His plump lips tremble as he holds your gaze. "I've been...touching myself just thinking about it! Even when I was with other girls, you were the one I really wanted! It felt so good to know you felt the same." He wriggles up against you, leaning up towards your face. For a moment you're convinced he's going to kiss you, and then you'll definitely break.

"No!" You grab him by the shoulder and push him away, rather firmer than you intended, the shove sending him sprawling across the couch on his back. You almost pounce on him, almost cover his body with your own and smother his lips with hungry kisses, but...somehow you hold yourself back. You're hardly even sure why anymore. "I can't Nick." You stammer, staring down at his wriggling body. He's so cute...so pretty, so needy, and if you just reached out now and took him, you could make him yours entirely, but he's your baby brother too. "I just can't, I'm sorry. You're going back to Dad's today, and we'll...never mention this again. That's final!" You snap the last words, silently praying he'll give in to you one last time. At this point you don't even care if he goes back to being surly and sullen afterwards, so long as he stops tempting you like this, stops making it so hard to resist.

"I'm not leaving." He stares back at you, a hint of challenge in his grey eyes. Fuck, you liked him better when he was mewling and meek. Already you feel a growing urge to put him back in his place joining the boiling temptation to shove your cock in him just out of lust. "I already called Dad and told him I was staying. He's not coming to fetch me anymore and I'm not leaving. I'm enrolling here, at this College, and I'm going to live with you. It'll save money, I said, and you'd make sure I kept on track with my studies. I'm not leaving, Lucy."

"Damn it." You spit, anger and lust fighting inside your shuddering body. Maybe you really should should drag him over your lap, pull down those adorable briefs and spank his bare butt good and hard until he's sobbing and begging for mercy again! That'll teach him to listen to his older sister like he should! Only it'll end with your cock in his holes just as surely as it did last night. You desperately try to think of another way to fix this. If your Dad thinks Nick is staying here anyway...you can't just kick your baby brother out onto the streets! And he does need to go to college, to sort his life out like you've always wanted him to! But you can't touch him again, you just can't! "Fine!" You snarl at him, your voice thick with lust. "You can stay longer if you have to, you spoiled little shit! But that is still never happening again! Never, you hear me? And as soon as I find a place in the dorms for you, you're moving straight out, if I have to toss you over my shoulder and carry you there myself!" The delicious image of Nick naked on your shoulder, his bare legs dangling over your chest as you carry him off like a prize, sends another pulse of pleasure through your shuddering body and you can't stop yourself from moaning. This is feeling like a losing battle more and more, but you can't do that to him again! With a strangled gasp, you rise from the couch. "I need a shower." You snap. A cold one, no, arctic. Anything that can help calm your throbbing erection before you strip your baby brother bare and bend him over the couch. As you turn and stagger away, you're almost certain you hear him mutter something under his breath in a sullen voice.

"Never? We'll see about that..."
