But Alan kept rising.
The first kiss landed just above the soft swell of her mound. A light brush, almost chaste, like a promise deliberately withheld. Madison’s sharp, plaintive moan slipped out before she could swallow it. Through the haze clouding her eyes she caught the briefest smile tugging at her little brother’s mouth. Then it vanished.
His hands moved downward at the same time, stroking the length of her calves before gliding back up her thighs, while his mouth continued its slow, relentless climb toward her chest. The contradiction of those movements threw her off balance. It felt as if two different men were touching her at once—one tormenting her with deliberate slowness, the other rising without pause toward her breasts. When his mouth finally closed over a nipple he groaned, a low, masculine sound that vibrated straight into her skin. Madison’s pussy clenched hard. A thicker trickle of slick slid between the cheeks of her ass. That sound had aroused her more than she wanted to admit.
He took her other breast in his hand and kneaded it with possessive pressure while his tongue and lips worked the first. Gentle and demanding at once. Madison’s hips began to roll on their own, seeking more contact, unable to stay still. Alan placed a firm hand on her thigh and eased it back down to the mattress. No words. Only that silent, commanding weight that said: stay down. Don’t move.
It was agony. Sweet, exquisite agony.
She was soaked, thighs parted despite herself. Alan savored every second. Her breasts were perfect under his tongue—warm, heavy, nipples tight and hard. He could feel how close he was to losing control; if he let his breathing slip, if his own arousal climbed too fast, he might come untouched just from sucking on them. He forced himself to stay measured, deliberate, breathing steadily against her heated skin.
His hands rose to her hips. He gripped them hard, fingers sinking into the soft flesh, and kept moving upward. When his face hovered directly above hers the moment seemed to stretch and hold. He looked her straight in the eyes. One hand stayed on her, thumb tracing slow circles on her hipbone. Madison trembled. She had no idea what he would do next. She didn’t know anything anymore. Tears welled in her eyes—not from sadness, but from the unbearable pressure coiling in her throat and low in her belly. She was right at the edge. He could feel it.
Then he lowered himself again.
He brushed her lips with the lightest touch—just enough to steal her breath—before settling into the curve of her neck. The kiss he gave her there was slow, deep, wet. His tongue dragged a hot line along her collarbone.
Madison came apart.
It wasn’t a simple moan. Her body arched sharply, hips lifting against the hand pinning her down, and a broken, strangled cry tore from her throat. Alan kept kissing her—neck, collarbone, the hollow at the base of her throat—slow to understand. Only when he felt her muscles fluttering in rhythmic waves, heard her cries climbing and fracturing, did it hit him.
She was coming.
From this alone. From his mouth on her breasts earlier, his kisses, the steady pressure of his hand on her hip. He hadn’t even touched her cunt.
Alan stilled, genuinely surprised. He lifted his head just enough to see her. Madison lay panting, face twisted in raw pleasure, eyes glassy with tears. She met his gaze with something defeated yet blazing with naked, hungry need. She had just come. Because of him. Without him going any further.
His hand rose to her cheek on instinct, thumb gently brushing away the tear that had slipped toward her temple. She didn’t move. Completely pliant now, offered, her body still rippling with small aftershocks. When he let his palm settle on the lower curve of her belly, just above her mound, Madison jolted hard—as if lightning had struck her. A moment later a long, low moan escaped her, sounding almost like a wordless plea.
She wanted him lower.
She wanted him there. Now.
Alan allowed himself a small, satisfied smile and finally went to work.
Alan found himself between her spread thighs. He lay flat on his stomach, face only inches from her sex. He didn’t even need to reposition her: Madison parted her legs wider on her own, by pure reflex, as if her body had already accepted what was about to happen.
She was playing along. Letting him do it. Yet deep inside she burned to touch herself, to slide her own fingers where he was still taking his time, to make herself come a second time if she had to. But she didn’t move. She waited.
Alan placed a hand on her first, palm flat against her lower belly, just above her mound. Madison jerked violently, as though a live wire had touched her. Her hips bucked despite herself. Then, seconds later, a long, low moan rose from her throat—almost a silent plea. She didn’t speak. She didn’t need to. That sound said everything: there. I want you there.
He began by stroking her with two fingers, slow, gliding along her soaked folds. Everything was already wet. Her pussy glistened under the room’s dim light, and every caress produced an obscene, wet sound. Madison bit her lower lip to keep from moving. The pleasure was too strong, too direct. She was holding herself back with everything she had.
Then Alan leaned in and licked her for the first time.
A long, slow stroke of his tongue from bottom to top, gathering everything she had already spilled. He took his time. He didn’t rush straight to her clit. He circled it, barely grazing, tracing lazy circles around it, licking the folds of her lips, drinking from her as if he’d been thirsty for hours. With his hand he kept stroking her, fingers sliding easily through that viscous heat. He was skilled. He knew exactly where to press, where to breathe, where to let his tongue linger without giving her what she wanted right away.
Madison was losing her mind.
Every pass of his tongue dragged a shiver from her. She felt his hot breath against her sex, his lips kissing her there the same way they had kissed her elsewhere—with the same cruel slowness. He teased the edges of her clit, circled it, brushed it with the tip of his tongue without ever taking it fully between his lips. Not yet. Not until she was completely lost.
She moaned louder. Her hips started moving on their own, seeking more contact. Alan placed a firm hand on her belly to hold her in place and picked up the pace slightly. His tongue grew more insistent, broader. He was licking her now with quiet greed, swallowing everything she gave him, and when he felt her clit swollen and hard under his tongue, he finally took it between his lips and sucked gently.
That was it.
Madison came for the second time.
