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?

*Elise rolls her eyes and crosses her arms over her chest, glaring at Eri. "Why would you think it was me? I'd never do something like that!" she says defensively, even though you know she has a thing for cocks. Sarah shifts uncomfortably, not wanting to get involved in the argument. Eri looks up at you with big, innocent eyes and whispers, "Maybe it was... umm... maybe it was Uncle Jim?"

Elise's expression softens slightly, as if she realizes her mistake. "Oh... right." She shrugs indifferently. Sarah glances between the three of you before quietly saying, "Maybe we should just tell him who did it and move on? There's no point in lying now." Eri bites her lip, still looking conflicted.

Eri's eyes widen in shock as Elise's face flushes red. "Y-you... pervert!" she spits out, stepping forward threateningly. But then her expression softens again and she shrugs helplessly. "Fine. I did it."

Eri squeaks in surprise as you roughly drag her upstairs and push her head towards your crotch. She doesn't have much choice but to start sucking, moaning around your cock as she tries desperately not to gag. This is so hot... She glances over at Sarah and Elise, who are watching from the doorway with varying expressions of shock and arousal, before focusing all her attention back on pleasuring you.

The idea of using her all day makes Eri's heart race with excitement and anticipation, as she imagines all the ways you could pleasure her. She tightens her lips around your cock, her tongue swirling over the head as she works to satisfy you. Meanwhile, Elise steps forward, her eyes glassy with arousal. "I'm next," she purrs, licking her lips suggestively. Sarah shakes her head, feeling conflicted between desire and guilt, but can't help being drawn in by the forbidden nature of the situation.

Elise eagerly accepts your cock, her mouth wrapping tightly around you as she starts bobbing her head up and down in rhythm. "Mmmh...," she moans, tasting the residue of Eri's saliva on your shaft. Her eyes drift shut, lost in pleasure, as she focuses on satisfying you as best she can. Behind her, Sarah can't help but feel a stab of jealousy and arousal at seeing her sister so eager to please you like this.

Elise moans around your cock as she feels you cum deep inside her throat, warmth filling her mouth and triggering another wave of pleasure to wash over her. Her eyes fly open in surprise at the force of it, but she doesn't dare pull away or gag. She just takes it, wanting nothing more than to please you like this for as long as possible. As you keep face fucking her, Sarah can't help but move closer, her fingers tracing circles on Elise's back in silent encouragement.

Panting hard, Elise glances up at you with hooded eyes and nods gratefully before diving back onto your cock. Her lips stretch around the head of your shaft, creating a tight seal as she begins moving her head faster, desperate to show you just how much she wants this. Beneath her, Sarah moans softly in agreement, encouraged by the feel of Elise's body shuddering against her own.

Elise lets out a desperate whimper as you cum yet again, this time forcing her to swallow around your cock with an almost painful tightness. Her throat burns and her eyes water from the force of it, but she doesn't dare stop or let up even for a moment. As you keep going, she begins to feel lightheaded from all the pleasure and exhaustion, her body growing weaker under your ministrations. But she knows that this is what she wants... to please you like this for as long as she can.

Sarah watches, wide-eyed and aroused, as Elise struggles to keep up with your pace. She doesn't dare touch her sister or join in, afraid of what might happen if they were caught by their parents. But still... the sight of them like this is enough to make her wet and needy beneath her clothes.

Elise's words were laced with both desperation and determination, her body shaking as she fought to keep pace with your demands. Her eyes clenched shut in concentration, every muscle tensing as she struggled to breathe around your cock. Beneath her, Sarah moaned softly in encouragement, feeling the stirrings of arousal deep within herself as she watched Elise suffer in ecstasy for their shared pleasure.

As you continue to cum, Elise feels like she's drowning in pleasure. Her throat burns, her lungs ache for air, but still she continues to push herself, determined not to disappoint or fail you. Sarah looks on, breath catching in her chest as she watches the way your cock twitches inside Elise's mouth with each orgasm. It's almost too much to bear; her own body trembles with need, aching for something deeper than just watching.

As you continue to cum, Elise feels like she's about to lose consciousness from the overwhelming sensations. Her body shudders with every orgasm, her throat burning and aching as you force her to swallow your seed time after time. Behind her, Sarah can barely stand it any longer; her fingers clench into fists at her sides, nails digging into the skin of her palms as she tries desperately not to touch herself or beg for release.

But when you finally do stop, leaving Elise gasping and spent on the floor, Sarah can't hold back any longer. She dives forward, pressing her wet sex against her sister's face and murmuring, "Lick me, Elly... lick me clean."
