He follows Derek's lead

"Touch yourself, Mark," he commands, never looking away from Sue's face. Mark's hand trembles as it moves to his crotch, his fingers tentatively rubbing the bulge in his trousers. His eyes are glued to Sue's exposed body, her pale skin flushing with arousal as Derek's skilled hands work her over. Sue's head is thrown back, her mouth open in silent moans as Derek's lips trail down her neck, leaving a trail of hot, wet kisses. His fingers pinch and twist her nipple, drawing gasps and whimpers from the married woman. Mark's breathing becomes more labored as he watches, his own arousal growing by the second. He unzips his trousers, his hand slipping inside to grasp his hardening cock.

Sue's body trembles against Derek's as he continues his relentless **** on her senses, his fingers twisting and pinching her nipple with expert precision. Her breath comes in short, ragged gasps, her back arching to press her breast more firmly into his palm. The room is thick with the scent of arousal, Sue's sweat-slicked skin glistening in the soft light as Derek's lips trail down to the swell of her breast. His tongue darts out, tracing the curve before capturing her nipple between his teeth, biting down just hard enough to draw a choked moan from her throat. Derek's teeth graze Sue's sensitive nipple, drawing another gasp from the married woman as she grinds against his thigh. The app's influence heightens her every nerve, making each touch and bite send jolts of pleasure through her body. Her blouse is now fully open, exposing the pale swell of her breasts as Derek's mouth works her over, his tongue swirling around the hard peak before sucking it into his mouth.

Mark watches transfixed, his hand now firmly gripping his cock through his open trousers. His breath comes in short, ragged bursts, his Welsh accent thick with arousal as he mutters, "Fuck, love. You look so beautiful like that." Derek's hand slides down Sue's body, his fingers tracing the curve of her waist before dipping below the waistband of her skirt. The app's influence surges through her, heightening her arousal as his fingers tease along her inner thighs. "Please," she breathes, her hips tilting forward, silently begging for more.

"Please what, Sue?" Derek murmurs against her breast, his teeth grazing her nipple. "Tell us what you want." Sue's eyes flutter open, meeting Derek's gaze before darting to her husband. Mark's face is flushed, his hand still working his cock as he watches the scene unfold. "I want," Sue's voice is husky with need, "I want you both." Derek's eyes darken with satisfaction, his fingers continuing their teasing exploration along the sensitive skin of Sue's inner thighs. He watches the way her body responds, the subtle tremors that run through her as his touch inches closer to her most intimate areas. "That's what you want, isn't it, Sue?" he purrs, his lips brushing against the swell of her breast.

"You want both of us. You want to be filled, to be used, to be shared." Sue's breath hitches, her hips pushing forward, seeking more of Derek's touch. Her blouse is completely open now, her pale breasts heaving with every ragged gasp. Derek's fingers finally move up to Sue's bare sex, teasing along the outer folds of her pussy. A soft moan escapes her lips, her back arching as she presses into his touch. "Yes," she gasps, her words laced with need. "Yes, I want both of you." Mark's hand quickens its pace on his cock, his breath coming in short, harsh pants as he watches his wife respond to Derek's touch. "Please," he begs, his voice eager and thick with arousal. "Let me touch her too."

Derek's eyes flick to Mark, a wicked smile playing on his lips as he considers the request. Derek's smile widens, a spark of approval lighting up his eyes as he nods at Mark. "Alright, Mark," he purrs, his fingers still teasing Sue's wet folds. "Go on. Show your wife how much you want her." Mark doesn't hesitate, scrambling out of his chair and moving to stand behind Sue. His hands tremble slightly as they come to rest on her hips, his breath hot against the back of her neck. Derek watches, his gaze dark with lust as he continues his sensual **** on Sue's sensitive flesh. "That's it, Mark," he encourages, his voice a husky whisper. "Feel how hot your wife is for us both." Mark's fingers dig into Sue's hips, his body rigid as he presses himself against her back. "Fuck, love," he murmurs, "you're so ready for us." His hands slide down to cup Sue's ass, squeezing the soft flesh as he grinds against her. Sue's head falls back, exposing more of her throat to Derek's hungry mouth. A soft moan escapes her lips as Mark's erection presses against her ass, his hot breath fanning across the back of her neck. "Yes," she breathes, her body arching to press her breast more firmly into Derek's palm. "Please, I need more."

Derek's fingers dip lower, parting Sue's wet folds as he feels her body tremble against his touch. Mark's hands knead her ass, his cock straining against his open trousers as he grinds against her. Derek's lips close around Sue's nipple, sucking hard as his fingers circle her clit. Sue's moans grow louder, her hips bucking against the dual **** of Derek's skilled fingers and Mark's insistent thrusts. "That's it, love," Mark gasps. "Let us give you what you need." His hands slide up Sue's sides, cupping her breasts as he nuzzles her neck. Sue's body quivers as Mark and Derek work in tandem, their skilled hands and hungry mouths pushing her towards the brink of ecstasy. Derek's fingers plunge deeper into Sue's soaked pussy, curling to hit that sweet spot as his thumb rubs furious circles on her clit. Mark's cock, now freed from his trousers, presses insistently against Sue's ass as he kisses and nips at her neck. His hands roam her body, tweaking her nipples and pinching her skin just hard enough to make her gasp. Sue's head lolls back onto Mark's shoulder, her mouth open in a silent scream of pleasure as her hips buck wildly against Derek's invading fingers.

Derek's fingers plunge deeper into Sue's dripping pussy, his thumb expertly circling her clit as he feels her body tense beneath his touch. Mark's cock throbs against Sue's ass, his hands roaming her body with increasing urgency as he kisses and nips at her neck. The air is thick with tension and arousal, Sue's **** moans filling the room as she teeters on the edge of release.

"Fuck, love," Mark gasps. "You're so fucking beautiful like this." His hands cup Sue's breasts, tweaking her nipples as he presses his cock more insistently against her ass. Sue's body trembles, her muscles coiling tighter as Derek's skilled fingers plunge deeper into her dripping pussy. Mark's cock throbs against her ass, his hands roaming her body with increasing urgency as he kisses and nips at her neck.

Derek's lips close around Sue's nipple, sucking hard as his fingers curl inside her, hitting that perfect spot. Mark's hands knead her breasts, his thumbs circling her nipples as he presses his cock more insistently against her ass. Sue's head thrashes back and forth, her body arching into their touch as her release builds. The combined **** of Derek's fingers and Mark's grinding cock against her ass pushes Sue to the brink. Her body tenses, muscles coiling tight as a powerful orgasm crashes through her. Sue's back arches sharply, pressing her breast more firmly into Derek's hungry mouth as a guttural moan tears from her throat. Her pussy clenches around Derek's fingers, soaking them as waves of pleasure ripple through her body.
