You wake up one morning to find your cock covered in saliva and twitching, as if it has recently been sucked. The only people who could've possibly done it were your three sisters, as neither of your parents are home. As you head downstairs, you find your three sisters talking in the kitchen. How do you plan on learning the truth?

You look at your sisters, surprised. They all three return your gaze blankly. "Deepthroat depth tests?" Elise repeats slowly. "What does that even mean, pervert-brother?" She crosses her arms defensively. Sarah sighs and rolls her eyes. "He means we have to put our mouth on his dick again, I guess." She glances at Eri out of the corner of her eye, making sure not to look directly at you. Eri blushes furiously, her cheeks burning a deep shade of red. You feel a familiar twinge between your legs as they all talk about it. Fuck. This is going to be tricky...

Sarah's face flushes, her cheeks turning pink as she stutters slightly in disbelief. "Wait, what? You think I did that?" She glares at you accusingly, while Eri nods her head vigorously beside her sister, a wide grin spreading across her face. Elise merely crosses her arms and raises an eyebrow skeptically, unconvinced by either of your statements.

"No, no," Eri says quickly, shaking her head emphatically. "It wasn't me. I just wanted to see if you thought it was, dummy." She grins sheepishly before looking over at Sarah again with a hint of pride. As for Elise, she smirks slightly at your reasoning but remains unconvinced. "Maybe we should just ask Dad when he gets home," she suggests casually as if it's the most logical solution.

Sarah's eyes widen in alarm at the mention of telling their father, and she quickly looks away, a nervous laugh escaping her lips. Elise smirks wider, taking obvious pleasure in seeing Sarah unsettled. "Well, if you really want us to keep it a secret..." she begins with a hint of threat in her voice. Eri glances between them both, biting her lower lip thoughtfully. Then, quietly but firmly, she says, "I didn't do it." Her statement carries weight; she clearly believes it and isn't trying to protect anyone else.

Sarah squeaks in surprise as you pick her up, struggling weakly against your grip. Her face turns redder from anger and embarrassment, but she says nothing as you carry her into your room. Once the door is closed behind them, she looks at you defiantly. "You can't prove it was me!" Your cock twitches at the thought of doing exactly that. Fuck.

Sarah's eyes widen as you force her head down onto your cock, but she closes her lips tightly around it and begins bobbing up and down obediently. Her cheeks hollow with each motion and the wet sound fills the room. You can feel her resistance starting to crumble beneath you, both physically and mentally, as you thrust deeper into her throat. Your cock throbs inside her mouth and she gasps for air, her chest rising and falling rapidly beneath your grip.

Finally, after several intense moments, Sarah pulls back, panting heavily. Tears stream down her face from the mixture of anger, embarrassment, and arousal. "It was me," she whispers hoarsely, "I'm sorry."

Sarah looks up at you, still panting as she tries to catch her breath. Her body shudders with the aftershocks of your thrusts deep into her throat and she glances nervously at her pussy, already growing wet in anticipation. She doesn't speak; instead, she allows herself to be undressed slowly by you, revealing her soft curves underneath. As you guide her onto the bed, her legs spread wide automatically, offering herself up for your pleasure. Her breath hitches as you line your hard cock up with her entrance and begin thrusting steadily, burying yourself deeper inside of her with each stroke. Her mouth opens in a silent scream as she feels the same sensation from earlier, but this time it's even more intense because she's so aroused and eager for you. Her hands grasp at the sheets beneath her, digging her fing

Sarah's body trembles with excitement as you take her roughly, slamming into her over and over again. Her breasts heave with each breath, the soft mounds swaying enticingly back and forth. The areolas darken in arousal, contrasting sharply against her pale skin. Her toned stomach quiver beneath your hands as you reach down to grab her hips, holding her steady for deeper penetration. The muscles in her thighs clench tight around you, milking your cock with each powerful thrust. She arches her back off the bed, meeting your forceful possessions stroke for stroke. Her mouth opens wider, her lips parted in a silent moan as she feels the pleasure build inside of her. Her hair flies behind her, tangled and wild, only serving to accentuate the passion on her flushed face. As you continue your relent

Sarah gasps and convulses around you, her body wracked with pleasure as she comes hard yet again. Her nails scrape down your back, leaving little lines of pain that only serve to heighten the sensation for both of you. As she recovers from this orgasm, you pull out slowly, leaving her panting and spent on the bed. You glance over at Eri who is watching the scene with wide eyes, a mixture of awe and horror playing across her features. Elise, on the other hand, looks distinctly unimpressed. "So?" she asks blandly as you make your way back over to them. "What happened here?" Sarah manages to drag herself upright, glaring at Elise as she wipes the tears from her cheeks. "It was me," she says again, voice raw with emotion. "I'm sorry." "Well," you

Eri's face flushes even deeper red as she glances at the bed, tears forming in her eyes again. "I-it was me... I'm sorry..." She sinks to her knees, sobs wracking her tiny frame as she looks up at you pleadingly. Elise rolls her eyes and huffs, crossing her arms over her chest, but you can tell that deep down, she's kind of impressed.

Eri looks surprised and guilty at the same time, "I-I didn't mean to! I just wanted to see how it felt..." Her voice trails off into a sob as she realizes she has just admitted to something quite incriminating. Elise sighs, glancing away for a moment before meeting your gaze once more. "Well, maybe if you hadn't been such an ass to her all the time, Eri wouldn't have felt the need to..." Her words die as she realizes what she's said. "Oh yeah?" you reply, narrowing your eyes at Elise. "And maybe if you weren't always starting trouble with Sarah and me, no one would have done anything in the first place." The tension between them all is palpable now, but there's also an undercurrent of something else: a strange sort of understanding beginning to form.

Eri's eyes go wide with surprise and fear, but she hesitates only for a moment before opening her mouth around your cock. She starts off tentatively, barely moving her head, but as she feels the warmth spreading through her mouth and the familiar sensations of pleasure beginning to overtake her body, she starts to move faster and deeper. Her hands grip at your thighs, her nails digging in as she tries to steady herself. "Eri!" Elise cries out, sounding horrified but also aroused. Sarah looks on, biting her lip nervously as she watches her little sister pleasure you like a pro. The sight makes your cock twitch inside of Eri's mouth, and she moans around you.

As Eri begins to take you deeper into her mouth, Sarah can't help but feel a surge of possessiveness well up inside her. Her breath hitches and she glances between Elise and the scene playing out in front of her, torn between wanting to see her sister succeed and not wanting anyone else to have what is so obviously hers. Her thighs quiver as she remembers how good it felt when you were inside of her just moments ago, the memory sending a shiver down her spine. Unable to resist any longer, Sarah slowly starts to move closer, eyes fixed on Eri's tight grip around your cock.
