It was a momentary relief when he left her hyper-sensitive clit alone, but then his tongue started touching other places--stroking along the inner flesh of her vulva, massaging her entrance where she was tight and stretched around Pete, her skin so taut and sensitive that she could feel the velvet-rough texture, each little bump of his tastebuds harassing her.
"Ah-h!" Linda tossed her head back. Her spine moved without her permission, her hips lifting and dropping, making Pete moan appreciatively as she fucked herself on his cock and her body squeezed tight around him with the struggle not to come. "Oh! Oh it feels so good, mmnn, oh my God I need to come so bad--"
"Shut her up, Pete," Daddy ordered, leaning against the wall beside the headboard. He was keeping a close eye on Linda, his gaze flicking from her flushed face to where her hips were straining up to meet the heavenly torture of Steve's tongue. He grunted in approval when Pete cupped a hand over Linda's mouth, muffling her desperate cries. "I guess we need to work on decorum."
Pete laughed breathlessly. "Linda doesn't have any of that, Dad. Ooh, yeah, that's great--keep doing that, Steve, she's getting so fucking tight--"
Linda whimpered, her vision darkening as her eyes rolled back in her head. She was tight around Pete, her whole body clenched to fight back the climax pounding inside her. She'd never felt anything so irresistible as Steve's tongue stroking her, and it felt like a soul-crushing effort to resist her body's desperate attempts to launch over the edge.
Not that she ever made it through a punishment without getting ruined--Daddy made sure of that--but this was going to be a bad one. The harder she was gonna come, the worse it was when they ruined it...and the orgasm boiling up inside her now felt huge.
She rolled her head to the side and blinked hard, trying to get control of her rolling eyes long enough to gaze up into Daddy's cold, impassive face. Her body twitched and jolted like a fish strung on a line, dangling on the edge of the forbidden release that she needed so badly, and she whimpered out one last desperate, wordless plea, entreating Daddy's mercy.
"Let me guess. You want permission to come?"
Daddy's voice was low and dangerous, and Linda knew it was hopeless, but she nodded anyway.
Daddy sneered "Yeah, I bet, you whore. You want to come like this, riding your brother's fat cock, with his friend servicing your clit like you're some kind of princess? Like you're something special?"
Linda nodded faster and faster, whimpering into her brother's grip. Her vision blurred with tears as it became harder and more painful to hold back the orgasm, to wait for permission that she knew wasn't coming. Her body fluttered inside, little false starts that she crushed back mercilessly, hanging on to the last of her control by the skin of her teeth, because maybe this time--maybe, just this one time--
"No. You don't fucking deserve that," Daddy said, and then patted Steve on the shoulder. "Finish her up, Steve."
Steve hummed in acknowledgement, and slurped his tongue up to Linda's clit again, swirling over it in a firm circle once--twice--three times--
"MMM MM-NN MM-NNN!" Linda cried into Pete's hand, her hips snapping and her spine curling as the last of her resistance frayed and the orgasm crashed over her.
And it was amazing, it was the biggest orgasm she'd ever had in her life--six months of frustration bursting out, caught between her brother's cock grinding deep inside her and Steve's tongue coaxing exquisite pleasure out of her clit, and she was in heaven--
--for less than a second.
Then, the rich pleasure of Steve's tongue vanished. In an instant, it was replaced by Daddy's fingers as he reached down and matter-of-factly grabbed her clit in a punishing grip, digging his thumbnail cruelly into the base of the delicate, spasming organ.
Linda shrieked and thrashed, the enormous climax evaporating into a series of uncomfortable cramps inside her, the pain cutting through and icing every ounce of pleasure. She was barely aware of Pete crossing the finish line himself, the rushing in her ears mostly covering the sound of his gratified groan as her agonized clenching milked his orgasm from him.
No pleasure, no relief for Linda. Only pain and betrayal, a stark emptiness inside her where the release she'd tasted was snatched away. Her mind filled with a heavy static as she struggled to withstand the pain and disappointment, the shaking spasms of her muscles as her body tried to make sense of it all.
Semen splattered hot across her cheek, bringing her back. Pete had let go of her mouth at some point--had she blacked out?--and she was sobbing raggedly. Steve was still kneeling on the bed in front of Linda, rapidly fisting his cock as it jerked and spat up at her face, an expression of supreme satisfaction on his face.
