The blindfold settled over his eyes.
For one last moment Alan could still make out the bedroom, the yellow wash of the lamps, the blurred outlines of the two figures. Then nothing. Absolute black.
A faint, almost sly tension closed around his throat. Rebecah’s giggles rang out somewhere close, high and mocking. Nearer still, Madison’s breaths—already shorter, already warmer. No images left. Nothing. Only that complete dark.
He had never felt this kind of control slipping away. And he was not ... entirely at ease.
A first hand came to rest on his thigh.
Alan jerked. The touch was warm, the fingers slightly uncertain. He clenched his teeth but left his arms where they were. He had to let it happen. That was the game.
The hand climbed slowly, stroking the sensitive skin just above his knee, then higher.
Rebecah spoke at the same time, her voice coming from exactly the place he pictured that hand: “You’re already rock hard...”
A second hand found him. On his chest this time. Soft. Sensual. Fingers slid along his ribs, traced a slow circle around one nipple, then drifted lower across his stomach.
Alan squeezed his eyes shut behind the blindfold—an absurd reflex. He told himself it was Madison. That she was the one touching him with that almost tender deliberateness.
Then a voice came, right beside the first, too close to tell apart: “You like that...?”
He couldn’t separate them.
The two voices seemed to rise from the same spot. Or nearly. Impossible to know which one was here or there, which fingers were on his thigh and which were drawing circles over his skin.
Rebecah laughed, clearly entertained by his silence.
“Oh ... he’s already lost.”
Both hands kept moving. One mapped his body with greedy, insistent hunger, nails scraping lightly now and then. The other had slipped lower, found his cock and closed around it.
The strokes began—slow at first, then surer. Alan felt his throat tighten. He could not tell anyone apart. Who was stroking him. Who was caressing him. Who was where.
Rebecah’s voice murmured: “So ... what do you think of your sister’s hands?”
Madison followed, more hesitant, almost shy: “Uh ... does it feel good?”
Again, impossible. Both spoke the same way, with the same quickened breath, the same tone carefully blurring every line.
Madison was playing the game. Completely. Alan could barely believe it.
Silence settled. Only a few breaths. Then Beca whispered: “Try ... to guess who it is...”
Alan never had the chance to answer.
A hot mouth, already slick with saliva, closed over the head of his cock.
Alan let out a rough cry.
His hips rose against his will. He clenched his teeth so hard his jaw ached.
He forced himself not to move. Not to grab that unknown head and shove it down to the root of his cock. Not to lose the thin scrap of control he still had left.
The suction came back harder.
The mouth was hot, ravenous. The tongue circled the head of his cock with almost cruel precision, licked the frenulum, then flattened and dragged the full length of the shaft down to the base. Wet, saliva-thick sounds filled the room. Greedy. As if that mouth had been starving for him for weeks.
Was it Madison?
Or Rebecah?
Impossible to know.
It was too good. Too precise. Too intense.
She pulled off all at once, leaving him in open air, his cock shiny and twitching. Alan heard a breath. A sigh a little deeper, a little rougher. Rebecah’s...?
He never had time to be sure.
A wet mouth pressed against his own.
The lips were full, the kiss deep, her tongue already inside him, demanding. He recognized her almost at once—by the taste, by the way she devoured him, by that slightly too confident way of taking control—that it was Beca.
And in the same instant another mouth claimed his cock.
Madison.
She took him in one clean stroke, all the way to the base, as if she had been holding back from the start, as if she had only been waiting for this moment to devour her little brother. Her throat clamped around him. A wet, muffled sound rose, then she pulled up slowly, leaving a long string of spit, before sinking down even harder.
The contrast made him reel.
On one side, Rebecah’s almost possessive kiss, her tongue exploring his, her teeth occasionally tugging his lower lip. On the other, his sister’s brutal, skilled mouth, sucking him without the slightest restraint.
She was sucking him while Beca kissed him.
He was certain. It was too good to be true. Too wrong. Too perfect.
The strokes on his cock sped up. Every descent was deep, every rise came with a tongue motion that dragged a moan out of him into Rebecah’s mouth. His hips jerked. He could already feel the pressure climbing too fast.
Rebecah broke the kiss first.
She pulled away with a wet sound, then slid downward toward Madison. Alan heard a whisper, a muffled laugh, and in the space of a breath Madison spat his cock out in a thick, filthy, obscene noise. She even moaned, with no fear of being caught—maybe even on purpose, so he would know for certain it was her.
Rebecah spoke again, her voice both mocking and soft: “So, handsome ... do you like it?”
Alan opened his mouth to answer.
A hand seized his cock with sudden, almost aggressive force and started stroking it hard. Tight fingers, brutal rhythm, too fast. The words died in his throat. He couldn’t finish the sentence. He couldn’t even start it.
Rebecah murmured, her voice still a little rough: “I think I’ve found someone more skilled than me...”
Madison answered only with a shy “Hmmm...”, as if she were accepting the compliment without quite daring to claim it.
The next instant Alan’s cock was plunged again into a hot, wet place.
