Pleased at first, then you panic

You wake slowly, finding your body wrapped in a warm cocoon of satisfaction that makes you smile. For once, you don't have the aching morning wood that insists you jerk off before doing anything else with yourself that day. Instead, your heavy balls feel nice and drained, and your cock is soft, drooping down between your legs. Your nose wrinkles at the scent of cum and sex filling the air, and for a moment you wonder if you had another wet dream. Then the warm, soft body lying in the crook of your shoulder stirs with an adorable little sigh, and you glance down to see your baby brother resting there beside you, drenched in dry cum.

For a moment, you pause, as all the blissful memories of what you got up to last night rush through your head. You spanked your baby brother's naughty butt, made him submit to you the way he always should have, then used his sweet holes to drain every drop from your aching balls. The thought makes you smile faintly, and you reach a gentle hand over his sleeping body to give his cum-covered butt a firm, affectionate pat. He stirs a moment, murmuring something under his breath, then relaxes back into your shoulder, still blissfully asleep. What a cute boy he is. This was just what both of you so desperately needed, you feel like you see that now. All Nick's naughtiness was just a cry for the kind of attention he secretly craved from his older sister and your own struggles with boys because the perfect one for you was so nearby all along. It just makes sense in your head, like a perfect picture, until it suddenly doesn’t.

It's a sudden, idle thought of your Dad that brings the whole thing crashing down around you like the roof just fell in. A sharp gasp of shock escapes your lips as you finally wonder just what he would think if he stumbled into your bedroom right now and found his two beloved children like this, naked and draped over each other. His eldest daughter, the calm, responsible one he could always rely on, just finished fucking her baby brother, the very boy she was supposed to be guiding and looking after and protecting! He'd be utterly horrified! And he'd hardly be the only one either. Somehow in the haze of lust and need that you allowed to utterly control you last night, it slipped your mind that incestual relationships aren't exactly tolerated, least of all when there's a more than ten year age difference between the horny New Female and her brother she took advantage of.

You're breathing hard all of a sudden, all that warm satisfaction slipping through your fingers like grains of sand. How could you have done this? It was a mistake, the biggest mistake you've ever made in your life. A sickly feeling of guilt and settles in your stomach like a cold pit. You feel trapped in this room, like an animal with its leg in a snare, only everything was your own fucking fault! Nick's warm, slumbering smile, the way he nuzzles into you so tenderly in sleep, each feel like an even worse mark of your betrayal of him and your family now. You took advantage of him, in the worst way possible, and it makes you want to vomit now.

You can't stay here. You've got to get out of this fucking room, away from the stink of sex which burns in your throat like acid. It's madness, you know. Your head screams at you to stay, wake up Nick and at least talk through what happened, but you can't. Not right now at least, not with your heat and gut twisting round each other inside you, leaving you gasping with the agony of it. With the gentleness you always should have handled your dear little brother, you lift him off your body, careful not to wake him, and lay him on the sheets beside you. He makes a muffled moan of protest, but doesn't stir, slipping back into an adorably deep sleep. You stare at him for a few more panicked moments, each one like another scar across your soul. He's so cute, so delicate....so ****. No wonder he tried so hard to please you when you **** him into sucking you off, he must have been just **** to get his kind older sister back!

With a **** gasp, you rise from the bed, tears in your eyes as you run for the bathroom. You taste bile, your stomach clenching. The sight of yourself in the mirror makes you feel even sicker. In all your life, you've never hated yourself more, you've never hated that thing between your legs more, no matter that the true blame lies in your head for not controlling your ridiculous New Female lust and choosing to do the unthinkable. All you can pray for is that Nick stays asleep until you can shower, get dressed and get yourself out of this fucking apartment and away from the evidence of the worst mistake you've ever made. You just want to run away, forget this...but you know you can't, you know Nick can't. But at least you need to calm yourself down first, before you can face him and apologize...somehow for the terrible things you've done to him.
