She's hesitant but willing

"Mark, what's going on?" she asks, uncertainty clear in her words. But before her husband can respond, Derek's hand closes around her wrist, pulling her gently but firmly towards him. Sue's breath catches in her throat, her body instinctively leaning into Derek's touch.

"Sue," Derek says, his words low and husky. "Your husband and I have been talking." Derek's fingers tighten around Sue's wrist, his other hand coming to rest on the small of her back, pulling her flush against him. Sue's breath comes in short, quick gasps, her body betraying her as it presses against his. "We've been discussing you... and your desires, Sue," Derek murmurs, his lips brushing against her ear.

"And how much you want this. How much you need it." Sue's eyes flicker to Mark, her husband sitting there transfixed, his body rigid with arousal and uncertainty. Derek's gaze follows hers, a satisfied smile spreading across his face as he watches the internal struggle play out in Mark's eyes. "Isn't that right, Mark?" Mark's breath catches in his throat, his gaze locked on Sue's body pressed against Derek's. He swallows hard, his Adam's apple bobbing as he struggles to find his words. "Y-yes," he finally manages, his face a mask of arousal and hesitation. "That's right, love."

Sue's chest rises and falls rapidly, her B-cup breasts straining against the fabric of her blouse. Her skin is flushed, a sheen of sweat glistening on her collarbone as she processes the scene before her. Derek's hand slides down her back, coming to rest just above the curve of her ass. "You want this, don't you, Sue?" he murmurs, his lips still brushing against her ear. "You want us both. You want to be shared, to be used, to be filled by both of us." Sue's breath hitches, her body quivering against Derek's as his words wash over her. She glances at Mark, seeing the lust and hesitation warring in his eyes. When she speaks, her words are soft, uncertain. "I... I do want this."

Derek's hand tightens on her hip, pulling her even closer as he feels her resolve crumble. "Good girl," he purrs, his words dripping with approval. "That's exactly what I wanted to hear." Derek's lips brush against Sue's neck, his teeth grazing her sensitive skin as he feels her body shudder against his. His free hand slides up to cup her breast, thumb rubbing teasing circles over the nipple that's visibly hard through the thin fabric of her blouse. "You've been such a good girl, Sue," he murmurs, his voice a husky whisper in her ear. "Your husband knows how much you crave this. How much you need to be used by both of us."

Sue's head falls back, exposing more of her throat to Derek's hungry mouth. Her hands clutch at his shoulders, nails digging in as she struggles to maintain her composure. Derek's teeth sink into the soft flesh of Sue's neck, leaving a red mark as he feels her body arch against his. His thumb continues its relentless **** on her nipple, twisting and pinching through the thin fabric of her blouse. "That's it, love," he coos, his Welsh accent thick with arousal. "Let go. Give in to what you really want."

Sue's breath comes in short, ragged gasps, her body betraying her as she grinds against Derek's thigh. Her blouse is now soaked with sweat, clinging to her curves and accentuating the swell of her breasts. Derek's hand slips beneath Sue's blouse, his fingers deftly unhooking her bra as he palms her bare breast. He rolls her nipple between his thumb and forefinger, reveling in the way her back arches and a soft moan escapes her parted lips. Mark watches transfixed, his own arousal evident in the bulge straining against his trousers. Derek's eyes flick to him, a wicked smile playing on his lips as he continues his **** on Sue's sensitive flesh. "Look at her, Mark," he murmurs, his words dripping with seduction. "Your wife, so needy, so **** to be used by us both."

Sue's body trembles as Derek's fingers continue their skilled manipulation of her breast, her moans growing louder and more ****. Her head lolls to the side, exposing the column of her throat as she surrenders to the overwhelming pleasure. Mark's gaze is locked onto his wife's exposed skin, his breath coming in short, ragged bursts as he watches Derek claim her.

"She's so beautiful when she's like this, isn't she?" Derek purrs, his lips trailing kisses along Sue's jaw. "So open, so willing." His free hand slides down Sue's belly, unbuttoning her blouse with practiced ease. As Derek's fingers work at the buttons of Sue's blouse, her body quivers beneath his touch. The garment falls open, revealing her pale skin and the swell of her breasts, which rise and fall with her rapid breathing. Derek's eyes darken as he takes in the sight, his hand sliding up to cup her breast once more. "You're so perfect, Sue," he murmurs, his words husky. "So responsive."

Mark's gaze is fixed on his wife's exposed body, his own arousal evident in the way his breathing quickens. Derek notices his attention and smirks, his fingers continuing their skilled manipulation of Sue's nipple. "Touch yourself, Mark," he commands, never looking away from Sue's face.
