At last, feeling herself close, Lara reared up on her haunches, her arms going around Finn’s neck, her hands on the back of his neck as she held herself against him, sliding her distended anal ring up and down on his pistoning cock.
Finn held her to him, his cupped hands holding her breasts as he thrust into her, with Lara pushing back against him as he jammed himself into her, wanting him to fuck her harder, faster, to ream her out; he could actually feel her wanting coming off her in waves, that low-grade telepathy siblings share on rare occasions for a few seconds telling him that what he was feeling from her was real.
Finn slid his arms down to wrap them around Lara’s waist, urging her forward. As she leaned forward, her hands flat on the bed to support herself, her rear tilted up, squeezing his cock even tighter. Finn groaned as his cock hardened to an almost impossible degree as he pumped in and out of her tight hole, ramming into her in a frenzy of need.
Finn suddenly released her waist and urged her forward onto her stomach, following her down so now she was lying flat on her stomach as he reared up over her, his hands planted on the bed next to her as he pistoned his cock into her tightest hole. Lara could feel him speeding-up, telling her he was on his short strokes, and she was almost there herself, the act of her lovely brother laying her down and sodomizing her so perfectly almost overloading her already dazzled inner-self.
Finn froze with a deep, heart-felt groan of release; his pumping cock suddenly stilled inside her as jets of hot spunk once more burst from his pulsating cock, bathing her insides with his hot tribute.
That was enough to trigger her own release, and Lara screamed as orgasm flared and swept through her, her body shuddering and quaking with the force of it, her eyesight dimming and her ears popping as wave after wave of pleasure pulsed from her centre, bathing her entire body in their hot glow. She shook and trembled for long seconds, mewling with the intensity of her final release, her clawed hands digging into the bedclothes as she pushed her rump back at him, taking him fully into her depths as he filled her with his seed.
Lara froze, holding position for long seconds as aftershocks flared and rippled through her, her heart pounding even as her convulsing rectum rippled powerfully, milking every last drop of sperm from her brother’s twitching, pulsating cock. At last she slumped back down on the bed, Finn’s cock sliding out of her as she disengaged, even the act of pulling herself off him triggering yet more powerful aftershocks as orgasm once more spun and ricocheted through her.
Finn collapsed on the bed next to her, as winded as she, both of them too blown to do anything except lie together, gently touching and caressing each other until the world came back into focus.
At last, Finn raised his head and kissed her neck tenderly, his arms once more tightening around her as he hugged her to him.
“Oh Christ all-fucking-mighty, that was amazing!” he murmured, “I want to do that again with you, Sissy, that was the best thing I ever… I mean… oh Sissy, you were… Jesus, that was so good!”
Lara sighed and nestled back against her brother, pulling his arm more comfortably around her, enjoying his warmth and feeling safe and protected in the circle of his arm.
“Oh Finny, that was just… incredible… I never thought anything could be like that, it was just so… so wonderful! I love you so much, Finny!”
Finn nibbled her ear, making her shift and giggle, and his hands shifted slightly, to once more cup and squeeze her breasts.
“I love you too, Sissy, I’ll never stop loving you; I want to keep on doing this with you forever! I don’t care what mum thinks, or what she says; you’re mine now, and I’m keeping you, so there!”
Lara reached up to stroke Finn’s cheek.
“I don’t think mum will have much to say, not now I know what she’s been up to!”
Finn was intrigued by that cryptic statement, but too blown to follow it up; other things were on his mind just then.
“Come on, Sissy, shower-time!” he grinned, gently pinching her delectable bottom. Lara reached down and lightly dragged a fingernail along his scrotum, Finn gasping as she did so.
“Will you promise to do all my bits this time?” she smiled tiredly, and Finn gathered her in, kissing her even as he once more squeezed and jiggled her taut buttocks.
“I’ll wash anything you want, as hard or as fast as you want it done, that’s a promise, only come on; you’re starting to doze, and we both really, really need a shower!”
After an enjoyable, relaxing hot shower, Finn and Lara retired to bed once again; Finn wasn’t sure what the exact time was, but his internal clock told him it was long after four in the morning, and they barely had the energy to climb into bed, but when they did, they slept like dead things.
PART 4: THE SECOND DAY
Finn woke suddenly, unsure what it was that woke him. A small tremor from Lara, spooned against him, alerted him that something was wrong, and as he put his arm around her, she turned a tear-stained face to him. Finn was nonplussed; he hadn’t seen her cry since she was a little girl, but he knew that something must be very wrong to upset her like this.
“What is it Sissy, why are you crying? Please don’t cry baby; tell me what’s wrong.” he murmured. Lara looked up at him, confusion and guilt in her eyes, and suddenly he knew why she was crying.
“Finny, what have we done?” she blurted out, tears thick in her throat. “This was wrong, I was wrong, I was so, so wrong! I tricked you into coming here because I wanted this, and it’s all my fault; you’re my big brother, I’m not supposed to do this with you, I’m not supposed to seduce you like this, I’m so sorry, Finny, now I’ve gone and broken everything! Please don’t hate me, Finny, please, I’m sorry, I’m sorry, I couldn’t help it, I just… I wanted you so much, oh Finny…!”
Finn held her close; right now she didn’t need a lover; this was big-brother time, the way it used to be long ago, before they’d grown apart. He held her close to his chest, letting his heartbeat soothe her, the way it did when they were younger and she’d come crying to him over something or other.
“Shh, don’t cry, it’s alright, Sissy, it’s all alright, don’t cry, baby-girl, shh!” he crooned softly, gently rubbing her back as she cried softly against him. “Everything’s alright, Lara, I don’t hate you, I’ll never hate you; this is me, it’s Finny, all I’ll ever do is love you, remember? I promised you I’d love you forever, and I will, only you, Sissy, no-one else!”
But even as he calmed her, his own guilt began to churn inside him; supposing she was right? He was her older brother; he was supposed to look after her, not sleep with her, and certainly not do the things they’d already done. Maybe she was right to feel guilty, because right now all he could see was a yawning chasm of problems for them; of all their friends, would anyone accept them as a couple? What about mum and Uncle Mike? They would be mortified, they’d be tainted by what he and his sister had done; incest was illegal, people went to prison for that, so how could they keep this secret, or go back to living ordinary lives again? How could they live with an elephant this big in the room with them? Could he and Lara live as outcasts, cut off from their family and friends, their past, everything that made them who they were? Everything came with a price; how high a price would they have to pay for what they’d done?
He became aware of Lara’s eyes on him, and with that came the certainty that she’d shared every one of his musings. As he looked into her eyes, over and above everything else, he was still aware of just how beautiful she was, tear-ravaged face or not. Her eyebrow quirked up and Finn answered the unvoiced question.
“Maybe you’re right, Sissy, maybe this was all wrong; perhaps we should go, just get out of here and try and pretend this never happened?”
Lara leaned up on her elbow to look into his eyes, her beautiful eyes huge and luminous, and her expression set and serious.
“If I thought for one second you really mean that, Finn Elliot, I’d kill you myself! I’m allowed to have five minutes of cold-feet, and that’s gone now; what I can’t do is forget how I feel about you, or pretend I never loved you; don’t ask me to do that, because it’s just not possible! Everything that comes after this weekend, we’ll handle, OK? I’m not letting you go, no matter what. I think we can have a life together, a good life; it’s a gamble I’m willing to take. There are no real certainties in life, Finny, but I’m certain of one thing, from the top of my head to the tips of my toes; I love you, and I’ll always love you; you belong to me, and I’m not giving you up; my life for you Finny, and only you!”
Finn felt his eyes pricking as Lara opened her heart for him, and gave up everything for him. It stunned and humbled him that she was willing to give up everything, her whole life, to be with him. She’d said things he didn’t know how to say, stirring him inside, making him understand properly just who she was and what she meant to him, and what he meant to her.
She leaned closer and kissed him once, softly.
“I know I can’t be your sister anymore; this whole “Sisterfest” thing has taken care of that; so that leaves two other choices; you can be my lover or my best friend. I already have a best friend, so I guess that leaves my lover, so that’s what I choose!”
Finn looked closely at her, unsure how to describe his thoughts and fears for their future, if they even had one, but as he made to speak, Lara touched his lips, silencing him.
