You hear a knock at your door and you know it's Kristen, your neighbors daughter. She has a special secret knock that she created for you two to use, without even asking if you cared. Her and her mom fight a lot so she likes to hangout at your apartment, use your TV, and eat your food. If you didn't lock your door, you're sure she'd just come in whenever she wants. Kristen is mostly harmless, except she asks for money occasionally. Which, you give her on occasion. Never a lot of money, but it's starting to get old.

KNOCK KNOCK KN-KNOCK-KNOCK (pause) KNOCK KNOCK

She hops up to the door and smiles. "Hey! How's it going man? You got a sec?" Her smile gets a little brighter as she leans forward, one hand on her hip. She knows you'll let her in; it's what she does here. A safe haven from her mom, who just won't shut the hell up about college and how Kristen should focus on that instead of partying and spending your money on clothes.

"So... I got some stuff going on with me and my mom..." She pauses for a moment, tilting her head slightly to the side. "Well, you know how she is... Anyways, I was wondering if maybe... I could have like... $50?" Her big blue eyes dart over to meet yours, hoping that you'll understand. It's not about you, she tells herself as she fidgets with the hem of her shirt. It's about keeping her mom off her back for a little while longer.

Her cheeks flush at your words; even with her mom's complaints and insults, it's still hard to hear that she might not be doing enough for someone like you. But... you always have been nice about it. "Uhh... I mean..." She shrugs awkwardly, staring down at the floor. "I dunno, man... It's just that I need it for something really important, and if I don't get it, I'm in so much trouble." She bites her lip nervously as she tries to find the right words to make you understand why she needs so much money this time.

Her eyes widen as you make your offer, her mind racing with the possibilities. It's crazy, but... it might actually work! "Uhhh... okay?" She says hesitantly, unsure if she should trust you enough to do something like that. You've always been a good friend and all, but this is a whole other level of intimate. Taking a deep breath, she asks tentatively, "What do I have to do?"

Her heart starts to race as the words leave her mouth; it feels naughty even just saying them out loud. Her cheeks flush bright pink again, and she looks down at her feet awkwardly, unsure of how much more of this she can actually handle before she either runs away or completely loses her composure.

Kristen looks at you, surprised and confused. "Excuse me?" She asks, tilting her head to the side. "My... My breast size? Why do you want to know that?" Her cheeks burn redder with every passing second as the realization slowly dawns on her what exactly it is that you're asking of her in exchange for the money.

She bites her bottom lip, hesitating for a moment before whispering back: "They're... like, a D-cup, I think." Her voice wavers slightly as she says this, feeling incredibly self-conscious and exposed. She crosses her arms over her chest protectively, trying to hide the fact that her nipples have hardened beneath her top in reaction to your words.

"So..." She trails off uncertainly, unsure of where to go from here or what else you might expect of her.

Tentatively, she starts to do as you've asked. Her fingers trembling slightly as they reach up to grip the bottom of her shirt and pull it over her head. Her breasts spill free from the loose fabric, jiggling lightly with every move she makes. She takes a deep breath, feeling incredibly self-conscious and exposed but also... weirdly turned on by your obvious interest in them.

As instructed, she pushes down her bra strap, letting it slide off one of her plump breasts entirely before tugging at the cups, shaping them into perky mounds that sit freely outside her bra. She arches her back slightly, thrusting them out further for your inspection as she whispers, "There you go... are they what you wanted to see?" Her nipples are hard and reddened from arousal now; she can feel the heat spreading through her entire body as she waits for your reaction. It's strange how quickly she's gotten used to this... and how much she likes it.

Her heart skips a beat as you admire her breasts; she can feel herself getting wetter at your words. She bites her lip and arches her back even further, offering herself up to you like some sort of offering on an altar. "I'm glad you like them," she purrs, feeling more confident now that she knows she's pleasing you in this way.

Her hands move slowly downwards towards the waistband of her jeans, already unbuttoning them without being told to do so. As soon as they're undone, she begins tugging at her underwear too, teasingly revealing the smooth curve of her stomach before pulling it all the way down to step out of. "Is there anything else you'd like me to do...?" She asks breathily, bracing herself against the door behind her as she stands there fully nude except for her socks and shoes.

Her body feels hot and heavy with desire; her nipples are hard as pebbles and achingly sensitive to even the slightest touch of air on them. She's never been this turned on before, and she finds herself wanting nothing more than to please you...and maybe get that money so she can get away from everything else for a little while longer.

Her heart pounds in her chest as she listens to your request. This feels so naughty and wrong but... the desire is too strong. She's never been one to turn down money, after all. And besides, this doesn't feel completely terrible; it actually feels kind of good in a twisted sort of way.

Without another word, she drops to her knees on the floor, positioning herself between your legs. Her hands reach out and grasp at your growing erection through your pants, giving it a few tentative strokes before wrapping her fingers around it tightly. She begins to pump up and down rhythmically, her other hand moving to stroke and tease your balls as she takes you deeper into her mouth with each thrust of her head.

Her tongue darts out, tracing circles around the crown of your cock as she sucks hungrily on it. She moans around you, feeling the heat of desire course through every inch of her body. This is so naughty and taboo but God damn does it feel good...

Her breasts sway enticingly as she moves her head up and down, taking more of you into her mouth with each stroke. She tightens her grip on your shaft, feeling the heat building inside her as she listens to your moans and gasps of pleasure. It's strange how easily this all came for her... maybe it was always there, just waiting to be unleashed.

Her hand leaves your balls briefly to fondle her own aching clit, rubbing circles around the swollen nub until she feels herself starting to build towards orgasm. Her mouth sucks harder on you as she comes closer and closer, wanting nothing more than to make you cum right now so that they can finish this... transaction and get back to being friends again.

"Gonna cum..." She moans around your cock, her voice sounding rough and needy even to her own ears. "You're gonna feel so good..." Her body tenses as she climaxes hard, her inner walls squeezing tightly around her fingers while her mouth still moves in time with the pulsing of your cock.

She looks up at you with glazed eyes, breath coming in ragged gasps as she waits for you to cum too. Her breasts rise and fall rapidly beneath her gaze, nipples hard and sensitive from the combination of pleasure and anticipation. She wonders what else she could do... or how far this would all go tonight.

Her breath catches in her throat as you instruct her to continue; the command sends a shiver down her spine and makes her even wetter between her legs. Nodding obediently, she takes your length into her mouth once more, sucking hard until she feels the head brush against the back of her throat. She pulls off for just a moment before taking you deeper, stretching her mouth wider to accommodate the girth of your cock as she begins to bob up and down more quickly now, using her tongue to stroke your shaft and tease the sensitive flesh at the base.

Her other hand leaves her breast to reach between her legs again, this time finding just the right spot to rub against with urgent strokes that match the rhythm of her mouth. Her back arches slightly as she lets out a needy moan, the sensation building inside her, making it harder and harder to concentrate on anything but the feeling of you filling her up and the pleasure coursing through every nerve ending in her body.

Her breasts jiggle enticingly with each movement, taunting you with their perky fullness as she takes you deeper and deeper into her mouth, her lips stretched impossibly wide around your cock until it feels like they could burst any second now. Her fingers dig into the skin of her thighs, feeling the heat building inside her as she nears the edge of orgasm again... but this time, she wants to wait for you to cum first. The thought of making you feel that good makes her even wetter, more needy, and it pushes her closer and closer to the brink with every
