Anna looks up with a serious expression then her expression softens. "Good job," she says approvingly. "Okay, you have earned a reward." She unbuttons the rest of her white shirts buttons and slides it off her shoulders. Zack's breath hitches in his throat the moment Anna's shirt falls open. His eyes lock onto her hands watching every movement with an intensity that makes the air between them feel electric. "Fuck, you are serious," he breathes out, his voice dropping to a low, hungry growl. He sets his math paper aside completely, giving her his full attention as if she is the most important thing in the room. His own breathing becomes heavier as she reveals the delicate lace of her bra underneath. Zack's hands clench into fists on top of his thighs, fighting the urge to reach out and touch her right then. "Keep going, I want to see everything you promise me," he commands softly, his gaze darkening with desire. He leans back against the headboard of her bed, making space for her but not taking his eyes off her for a second.
Anna slowly moves the strap of her bra off her shoulder; her movements are seductive and teasing. Zack's knuckles turn white as he grips the light purple comforter beneath him, his entire body tense with anticipation. The way he fingers hook into the strap of her bra, slowly sliding it down her shoulder– it is torture in the best possible way. "Goddamn it, Anna. You are killing me here," he rasps out, his voice strained with barely contained lust. His tongue swipes across his lower lip involuntarily as he watches the fabric slip further, exposing more of her smooth skin. The sight of her pale shoulder contrasting with the dark lace sends a jolt directly to her groin. "Take it off completely, I want to see those perfect tits bouncing while you ride me later," he demands softly but urgently. His hips shift restlessly on the mattress, betraying how badly he needs this reward after finishing his mathematics assignment perfectly for her.
Anna unhooks her bar and lets it fall onto the bed. Her nipples harden as they make contact with the cool air. She cups one of her breasts. "Do you like what you are seeing?" she asks seductively. Zack's mouth goes dry at the sight of Anna's bare breast cupped in her hand. His pupils dilate as he drinks in every detail– the way her nipples pucker and darken in the cool air, the gentle swell of her curves framed by her arms. "Like what I see?" he repeats hoarsely, shaking his head slowly. "Anna, you are fucking perfection. Those are the most beautiful tits I have ever seen in my life." His voice cracks slightly as he speaks, his gaze fixed on her chest like a magnet. Without conscious thought, his hands reach out toward her automatically before catching himself and balling into a fist against the mattress. "You have no idea how many nights I have jerked off thinking about these. Fantasy does not come close to reality," he admits roughly, his breathing growing heavier. He shifts forward on the bed again, closing some of the distance between them but stopping short of touching her just yet.
Anna smiles then she moves back and off the bed. She spins around to face him, seductively she unzips her black miniskirt and lets it fall to the floor at her feet, so she is only wearing her black laced panties. Zack's green eyes follow the black miniskirt pooling around her ankles, his jaw slackening as he takes in the full view of her standing there in just her black lace panties. The contrast between the dark fabric and her pale skin makes his cock throb painfully against his jeans. "Holy fuck," he breathes out, his voice rough with barely restrained hunger. He stands up abruptly from the bed, unable to sit still anymore while she stands there looking like a goddess sent to torment him. His hands flex at his sides as he fights the urge to cross the room and pin her against the wall immediately. "You are trying to kill me, are you not?" he accuses playfully, taking a step toward her. "First the shirt, now this- you are driving me absolutely insane." His gaze drops to where her thighs meet beneath the lace trim of her underwear.
"Do you want me to stop?" Anna asks teasingly. "Because I could put my clothes back on…" Zack's green eyes widen on genuine panic at her threat, and he immediately shakes his head violently. "Don't you dare fucking stop," he growls, closing the remaining distance between them in two long strides. His hands shoot out to grab her hips possessively, pulling her flush against his chest so she can feel exactly how hard he is for her. "Put you clothes back on, and I swear to god I will rip them off you myself." His forehead presses against hers, their hot breaths mingling as he looks down at her with desperate need. "Keep going, Anna. Show me everything. I need to see every inch of you before I lose my mind completely." He said grinding his teeth. "But it might distract you… you still have to do your English essay," Anna says softly, swaying lightly with her hands behind her back. Zack's head snaps back as if she had slapped him, his expression shifting from raw lust to incredulous disbelief. "My English essay?" he repeats, like the words themselves are foreign to his current state of mind. He lets out a short, sharp laugh that has no humor in it. "Are you fucking kidding me right now? With you standing there in nothing but those tiny black panties, you think I can focus on fucking Shakespeare?" His hands tighten on her hips, fingers digging into her soft flesh as he pulls her even closer. The hard ridge of his erection presses instantly against her stomach through his jeans. "Forget the fucking homework," he says, his voice dropping to a dangerous whisper. "I am not doing another assignment tonight. My only priority is getting those panties off you and making you scream my name until your sister comes upstairs to check on us."
