Megan
“I slept with Millie last night,” you say matter-of-factly. You don’t want to stir up rivalries, just want to inform. Surely Megan guessed that after the show right now. But you still have to give her the opportunity to catch up. And she takes hold of it immediately. Without losing another word, she grabs you, pulls you on her and immediately starts to destroy your boxer shorts.
“We have twenty minutes until Millie is finished,” you squeeze out, then her lips capture your mouth. With flying fingers she frees you from the last remnants of fabric. She is so fast and greedy that you can hardly follow her. First her hands are in your hair, then on your chest, then again on your cheeks, then they clasp your butt. At some point you are able to wring your sister down and tame her so far that you can look at her for a brief moment. Her looks and laughter are almost hysterical when you grab your cock and push her roughly back into the pillows. She yells happily and throws her arms up as you literally jump between her legs. You’ll have to thank Dad later for the big bed. Sure, of course…
Megan laughs full of anticipation as you push her thighs apart and come closer and closer to her opening. She wraps her thighs around you and is already out of breath while her legs press your pelvis hard against hers. She opens her eyes and mouth wide when you boldly enter her and smiles at you triumphantly.
“Oh God finally!” Her eyes are wide open to be able to absorb every fiber of your body every second and every movement you make. It’s a wonderful feeling. Both you and Megan had other partners and you throw all caution overboard when you enter her and push between her legs. Her walls wrap around you and seem to pull you further and further into your waiting Sister.
Megan supports herself with her hands, lifts her pelvis and meets your trust with animalistic pleasure and a mad grin. Your bodies bang together and it is loud enough that someone could hear it, but you don’t care. You pull Megan close to you and she clings to your back with all her might while your trusts make smacking noises in your girlfriend’s lap and send shivers through her entire body. Her legs wobble beneath you and try to find a hold. You smash into her faster and faster and your sister has to bite her tongue to avoid screaming in ecstasy. Her face shows the look someone could interpret as pain but you know it is the joy of being with you, under you. She comes closer to you again and after a long and greedy kiss, you feel a sharp pain in your shoulder, but don’t really feel it when your hands run over her neck and turn back to her wonderful round tits.
This time you are not so tender and with a shrill but suppressed squeak you pinch and pull them with a wide grin. It has the desired result and Megan, trembling and twitching, comes to a climax that turns her face red and from that you fear it may cause permanent damage. It does not matter for her. Go on now! Her mouth forms silent words of tribute to you and your skills which only spurs you on even more. You can’t count the years on two hands in which you wanted to do all of this to her. Long, bitter Years of waiting, silently longing for her. So many days in which you wanted to touch her even more. To show her your feelings. And now, on this glorious day and thanks to your dearest princess you can have it. The moment that counts.
You fuck your sister even though she falls weakly on the pillows with widened eyes and open mouth. Without words her hands spread her pussy for you and you keep ramming into her for dear life, driving her into the sheets until her head has disappeared into the mountain of pillows and blankets. Again, you pull her nipples, even more vigorously, and her arms flick up and squeeze out onto the mountain of bedding. Megan screams her next orgasm as loud as she can, luckily muffled by the fabric. Those were two orgasms so close together that you think Megan would have felt them to be one. She kicks her legs and shrieks under the pillows. Her body rears up and you still smash into her with all you have while her taut but soft stomach cramps with tries of breathing while she screams out her love for you. Driven to make her come as often as she might have fantasized. She is completely silent now. You don’t see her face, but all the muscles in her body are tense to the point of tearing. You still push on, driven by an incredible desire to let this girl come as she has never come before. To make all the years worth waiting. She needs it, deserves it. You need it as well. You want her to come more than anything in this moment. You want to give her an orgasm which she will never forget.
Her hand’s clench, almost panicking for something to hold on to. You give her your arms and she almost tears them off your shoulders. Her knuckles are pale as ivory but she’s still lifting her pelvis for you in rhythmic trusts. Her cunt is so tight that you can push in with all your strength and feel everything.
Finally, she breaks and screams again louder than ever and that takes all remaining strength away. Then, finally, you come, moaning, in her too. For twelve, thirteen, fourteen strokes you flood your sister’s cunt wit your hot seed and it feels like the best thing to do. Like you were born to do this. You form a bind with her and she accepts it with love and passion. Her fingernails run over your forearms and leave red marks on your skin. Her legs twitch uncontrollably in the bedsheets and her body is shaken as if under high voltage. It’s so awesome that you forget to breathe while zour wombat comes a third time. When you finally emptied your balls completely, you collapse over her and also fall into the mountain of pillows and blankets. Only your panting is heard, then Megan moves and painfully slowly pulls the pillow off her face. She leaves it lying next to her without strength. Her face is covered in sweat and her hair sticks to her everywhere. Her head is bright red and her lips are white because she squeezed all the blood out of them and you are sure that you look the same. You two look at each other, almost shocked by the intensity of your encounter.
Noises are slowly entering your world again. You sit on the edge of the bed with trembling knees and look over your shoulder at your bedmate, who is still lying crooked in the sheets. You smile weakly. It takes you a few minutes to collect yourself, then Millie comes through the door. Freshly showered and with her hair still wet, she looks like a stylish and new car compared to a Ralley car that won the Baja California. Her eyes alternate between you and her beloved big sister and she is a bit shocked by the sight of her. Then you all have to laugh.
You put on your shirt and find your boxer shorts on the floor. While you get dressed your sisters eye you and when you bend over Megan gives you a big slap on the butt. You only look at the two meaningfully, but don’t care about it anymore, while Megan musters your body like a piece of meat.
“Help me up,” she says after you’re done laughing and you pull her forward. Millie helps you and after your sisters have dressed, there is a strange silence between you. The girls see themselves naked more often than you do, which is natural. But from now on that’s something that will change drastically you notice.
And with that a dark shadow creeps onto your mind.
