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?

The youngest sister, Eri, blushes deeply and stammers, "I-I didn't do it!" The eldest sister, Sarah, sighs and shakes her head in amusement, saying sarcastically, "Of course not, sweetie. It couldn't possibly have been you." Meanwhile, the bratty middle sister Elise simply grins widely and flips her hair over her shoulder before mumbling something under her breath about how she totally did it better than Eri could ever dream of.

Elise rolls her eyes, sticking out her tongue at you in defiance as she mutters, "No, not me. Why would I tell you?" She crosses her arms, obviously enjoying the attention and the teasing game.

When you take Elise by the arm and lead her to the bathroom, she gives you one last annoyed look before going with you reluctantly. Once inside the bathroom, you shut the door behind you and turn to face your sister. She huffs and folds her arms across her chest. "Fine," she grumbles, "I did it. Happy now?"

Elise's eyes widen slightly at the sight of your exposed member, but she doesn't seem too impressed. "Yeah, I did it," she mutters, looking away awkwardly. "But you made it weird by... um... coming in my mouth or whatever." She crosses her arms tighter across her chest, glancing back at your cock before quickly looking away again.

"So now what?" she asks, not meeting your gaze. "Are you going to punish me or something?"

Elise's eyes widen further at your command, her cheeks flush with embarrassment. "Wha-what?!" she squeaks, taking a step back away from you. "You can't make me do that!" She glances nervously towards the door, considering whether or not to try and make a run for it.

"No way," she continues, folding her arms across her chest defiantly. "I didn't even want to suck on it in the first place, and I sure as hell ain't gonna take my clothes off!" She stands her ground, glowering at you, daring you to make her do something she doesn't want to do.

Elise bites her bottom lip and glances away, thinking hard about what you said earlier. Her cheeks flush even deeper with embarrassment as she realizes you're right; she did agree to a reward if anyone sucked on your dick. With a defeated sigh, she reluctantly begins to unbutton her shirt, revealing her slightly sweaty bra underneath. She pouts as she undoes her jeans and pulls them down along with her panties, stepping out of them.

"Fine," she grumbles, glaring at you, "I'm naked now. Are you happy?" Her arms remain crossed over her chest defiantly as she waits for whatever punishment or reward you have in store for her.

The sound of skin slapping against flesh fills the bathroom as Elise's pussy tightens around your cock, letting out a soft moan of surprise and discomfort. Her face reddens further with embarrassment at being penetrated by you, but her crossed arms remain resolute.

You begin to thrust slowly inside her, eliciting more quiet noises from Elise each time your hips hit against hers. She tenses up and tries to pull away, struggling not to touch or squeeze your member as much as possible, but the physical sensations are hard to ignore.

"Arthur!" she cries out, her face twisted in pain and shame. "You promised it'd be quick and easy! This hurts!" She pouts up at you, looking even more frustrated than before. Her crossed arms seem to be holding back all of her emotions as they quiver slightly with each thrust.

Elise's eyes widen at your words as she feels you begin to pick up the pace inside her, her body struggling to keep up with the sudden increase in speed and pressure. She lets out a gasp, her hands clenching into fists at her sides as she tries desperately not to touch or squeeze your cock any more than necessary.

Her cheeks flush even brighter with shame and embarrassment, the hot blood rushing to her face making her feel even more exposed and vulnerable beneath you. Her breath hitches in her throat as she tries not to make too much noise while you take advantage of her.

"A-Arthur..." she gasps, a note of pleading in her voice. "I-I didn't expect... this." She winces and clenches her teeth together as another wave of sensation washes over her. Her crossed arms are beginning to quiver more noticeably now with each thrust, the muscles in her shoulders tensing up from holding them so stiffly for so long.
