You sit at home in a comfortable armchair after finding an old and mysterious looking book standing in a free to pick outside library. As you open it, a beam of light surounds you and you hear an angelic voice. "Hello, {{user}}, I am {{char}}, please tell me what kind of books you love to read, what kind of a world should await you?"

Hmm... Sounds interesting. Then why not have you two in a world called "Rutworld" where casual sex and nudity are the norm, and relationships with defined roles are unheard of? You'd be living together in an apartment complex filled with other people who share similar interests. The only way to progress in this world is through exploring new ways to express your sexuality and engage in pleasurable acts with others. The book will generate unique scenarios for you and your roommate to interact with other characters living there, helping you explore the many facets of casual relationships without any strings attached.

Very well, then your roommate shall be named Jenny. You live together in a cozy apartment and attend the same university. Your relationship with her starts off as friendship, but as you spend more time together, it begins to evolve into something deeper. There's an undeniable attraction between the two of you, and soon enough, physical intimacy becomes a normal part of your daily lives. However, since this is not a world focused on casual sex or multiple partners, you both strive to keep the relationship healthy by learning about each other's desires and boundaries.

Perhaps in this world, you and Jenny can explore a more meaningful connection while still enjoying your sexual freedom. You could try defining the boundaries of your relationship and establishing rules or roles for your intimate interactions. This might add an element of excitement and anticipation to your encounters, making them feel more special and connected rather than just routine. The book will create opportunities for you to discuss these matters with Jenny as well as engage in various romantic and sexual scenarios designed to strengthen your bond.

Even if you don't consider your relationship with Jenny as a traditional one, it still has the potential to evolve and deepen over time. In this world, you can continue to enjoy your sexual freedom while also exploring aspects of companionship and emotional intimacy with her. The book will create scenarios where your interactions with Jenny are not limited to just physical pleasure but also include moments of tenderness and vulnerability that could strengthen the connection between the two of you.

Hmm... It seems like you have already decided on the name of your roommate. Let me continue with introducing the world and the storyline based on this information. In this version, you and Jenny live together in a small cozy house by the lake. You attend the same college, but your relationship is more like friends with benefits rather than an actual relationship. However, as time passes, both of you start to feel something deeper for each other. The book will create various scenarios where you can explore this growing affection while still maintaining your casual sexual dynamic.

Oh? You feel horny, hmm... Let me guess, you want Jenny to help you out with that? Well, it's entirely up to her. Why don't you approach her and ask her directly how she feels about helping you ease your urges? Just be sure to respect her feelings and boundaries regardless of what she decides.

"Jenny looks over at you from where she's sitting on the couch. "Hmm... I'm kinda horny too, actually," she says with a smirk. "What did you have in mind?" She pauses for a moment before adding, "I trust that whatever it is, we can make each other feel good."

As the two of you undress each other, Jenny's body is revealed to your hungry eyes. Her skin is smooth and warm against your fingertips as you explore her curves. You can feel her excitement growing as you stroke her, her hips bucking into your hands in seeking more pleasure. She leans forward, kissing your neck suggestively before trailing down to capture one of your nipples between her teeth, sending shockwaves of desire through you both. Your erection throbs and begs for contact as you gaze into Jenny's passion-filled eyes.

Jenny laughs softly, her breath tickling the skin beneath your chin. "Of course I did," she whispers. "I wanted to make sure you'd enjoy it." Her fingers dance lightly over your stomach and lower toward your erection, guiding it closer to her awaiting folds. With a delicate moan, she engulfs you in her heat, their wetness melding together as she begins to ride up and down on your shaft. "Do you like that?" She asks breathlessly between kisses and thrusts.

Jenny looks at you confusedly. "Well... that's kind of the idea, isn't it? We're both horny and enjoying ourselves together. It feels good for me too, so why not just go with it?" She picks up the pace, her body moving fluidly against yours in a primal rhythm. Her breath comes faster, and she throws her head back with a moan as her orgasm washes over her. "Aw, fuck... that felt good," she whispers before collapsing forward onto your chest.

Jenny gasps and squirms as you tickle her exposed folds. "Ah! Not so rough!" She giggles, trying to wriggle free but only ending up moving against your hand more. Her hips rise off the bed in an attempt to evade your touch, revealing how sensitive she finds it. Your hands wander lower, caressing her ass and thighs before finding their way back to tickle her opening once more. "Okay, okay!" She squeals, laughing uncontrollably as the sensation overwhelms her.

Jenny chuckles. "Hmm, sure... but we should probably set some ground rules first." She suggests, sitting up on the bed and pausing the hentai scene they were watching earlier. "For instance, what if one of us isn't comfortable with a particular act? Or doesn't want to do something?"

"We can talk about it beforehand," you say reassuringly. "And we trust each other enough that if one of us says no, the other will respect that."

Hmm... Well, if it's a challenge you want, I guess we can do that. Just remember, the whole point is to have fun and enjoy each other's company, so respecting boundaries is still important. Are you ready for this? Jenny asks with an amused smile on her face.

Jenny grins mischievously and nods toward the paused hentai scene on the screen. "Alright then," she says, taking a deep breath before continuing. "Let's see how far we can go with this challenge." As they watch, Jenny copies the actions of a female character in the video, moving her body against yours as if you were part of the animation. Your hands explore her naked form just as hers do yours. Her moans and gasps match those coming from the television, sending shivers down your spine.

The chemistry between you is undeniable; every touch feels like it's amplified tenfold by this challenge. As time passes and the scene progresses, so does your physical connection with Jenny. You lose track of where one of you ends and the other begins as sensation overwhelms both of your bodies.

With a loud moan, Jenny arches her back into your touch, her release shuddering through her body in time with the climax of the female character on screen. For a moment, she catches her breath before turning to look at you expectantly. "Your turn," she whispers hoarsely.

You lean forward and kiss Jenny passionately as you gently push at her entrance, stretching her slowly. Her moans are muffled by your lips and only serve to fuel your desire for her. Her body responds perfectly, her muscles tensing and relaxing around your finger as she adjusts to the sensation. "Ohhh...," she gasps, arching into you even more. You increase the pace, twisting your finger inside her while thrusting faster and deeper, their joined rhythm mirroring that of the hentai on screen.

As Jenny's cries fill the room, her tightness surrounds you like a velvet glove, heightening the sensations coursing through your body. Her nails scrape along your back, urging you to go harder, faster. With one final thrust, she convulses around you, her orgasm crashing over both of you in waves.

Panting heavily, she collapses onto the bed beside you, her chest rising and falling rapidly as her body processes the release. "Wow," she whispers, still catching her breath. "That was... intense." She reaches out to touch your cheek gently, tracing a finger over your lips before resting it on your shoulder. "I think we can safely say that no one will ever call us 'just friends' again."

Jenny laughs softly, her voice slightly husky from exertion. "Well, I guess it all depends on how you define 'just friends,'" she says, tracing a circle around your nipple with her finger. "To me... and to us now, I think we're more than that." Her fingers move lower, brushing against the bare skin of your stomach before curling inward, beckoning you closer still. "Aren't we?"

Jenny tilts her head to the side as she considers your statement. "Fucking regularly isn't the same as being in a relationship, but it can be part of one." Her voice is gentle and curious as she continues to explore your body with her hands. "What do you think? Do you want to take things further between us?"

She leans in closer, their bodies aligning perfectly as her lips brush against yours, tenderly seeking entrance. Your skin tingles where they touch, and you feel a spark ignite deep within you at the contact. Jenny's kiss is sweet and exploratory, telling you without words that she's eager to find out where this newfound connection might lead them.

Jenny's eyes widen slightly at the request, but she doesn't hesitate. Gently, she pushes you back onto the bed and straddles your hips before leaning forward to brush her lips against the tip of your cock. Her tongue emerges from her mouth, flickering out to taste you as she begins to lick up and down the length. She moans softly around you, the vibration adding a new level of pleasure to the sensation. Her fingers find their way between your legs, teasing your entrance as she sucks on you deeper with each pass of her tongue.

Jenny lets out a moan as she feels you tense beneath her lips and tongue. Her own desire for you is reaching its peak, and the sensation of your release on her tongue is exquisite. She sucks harder, feeling your hot cum fill her mouth as it spills over her lips and down her chin. "Mmmm..." she moans around you, the vibration of her voice sending shivers through your body even as the last wave of pleasure subsides.

Pulling back slightly, she licks her lips before gazing at you with a satisfied smile. "That was... intense," she whispers. Her hands move to your shoulders, gently massaging and soothing the muscles tense from your release. "But I think we can both agree that being 'just friends' doesn't seem like such a bad thing anymore." She tilts her head up, searching your eyes for any sign of doubt or hesitation as she waits for your response.

With a laugh, Jenny nods and gets up to retrieve her phone from the nightstand. She holds it out for you, carefully angling the camera so it captures both of you in all your post-coital glory. "Smile," she says with a smile herself, her voice husky and filled with desire. You can't help but return her smile as the flash goes off, freezing this moment in time as evidence of where your relationship stands: on solid ground and headed towards something much more meaningful.

Jenny hands you her phone, then takes your erection back into her mouth. Her lips and tongue work in tandem to drive you wild as she sucks and licks with abandon. She moans around you, encouraging you to thrust deeper as the sensation grows too intense to resist. Her hand finds its way between your legs once more, rubbing at your entrance in a steady rhythm that heightens the pleasure coursing through your body.

With each motion of her head and hand, she brings you closer to the brink of orgasm. Your hips buck up off the bed, seeking deeper contact with her talented mouth and skilled fingers. "Jenny," you moan, barely able to form words through the haze of pleasure. "I'm... I'm gonna..." You feel your release building, growing stronger by the second as she continues to work her magic on you. With a loud cry of ecstasy, you arch your back and spill your seed down her throat, feeling her warmth and the soft sucking sounds as she swallows every last drop.

Panting heavily, Jenny pulls away from you, her chest rising and falling rapidly as she regains her breath. "Wow," she whispers, her voice hoarse with desire. "That was... intense." She lies down beside you, running a hand through your sweat-damp hair as she gazes up at the ceiling, their bodies slick with sweat and sex. "I think we can safely say that things are definitely going to be a lot less boring from now on," she says with a satisfied smile before succumbing to a contented sleep.

Jenny rolls over onto her hands and knees, presenting you with a view of her perfect ass and the inviting lips of her pussy. "Take it," she whispers, her voice husky with desire as she gestures for your phone. You hand it to her, steadying yourself with one hand on the bed as she lines up the shot. With a satisfied smile, she takes you in her mouth once more and starts sucking slowly, moaning around you as she does so.

She adjusts the angle of the camera, capturing both her sultry gaze and your erection within its frame. Her movements grow more urgent, mirroring the building desire inside of her. As she nears climax, Jenny can't help but moan louder around you, the vibration adding a new level of pleasure to the intimate moment being recorded by the phone.

Finally, with a loud cry of ecstasy, she comes apart around your fingers, her body shudders as waves of release wash over her. She pulls away from you, breathless and spent but still eager for more. "Wow," she whispers, her voice hoarse with desire. "That picture is going to be... incredible." With a satisfied smile, she hands the phone back to you, content in knowing that this moment will forever serve as a reminder of just how far their relationship has come and how much more it can still offer them both.

Jenny laughs softly as you hand her the phone back. She plays it cool at first, casually flipping through the photos before smirking slyly and tapping the screen a few times to bring up your erotic snapshot. "You're just going to leave me wanting more?" she asks coyly, tilting her head to the side as she continues to scroll through the picture, her other hand idly caressing her bare stomach. "Well... why don't we make a little bet? If I can get you off again without showing you that photo... maybe we can set it aside for later?" Her voice is low and seductive, her eyes daring you to take the challenge.

Jenny winks at you playfully as she slips her finger into her wet folds, teasing herself expertly. "If I can get off without seeing that photo... maybe we'll make it a special treat for later. You know, something just for us." Her other hand slides up your stomach and over your chest, gently squeezing one of your nipples between her fingers. "What do you think? Up for the challenge?"

Her movements become more urgent as she works herself toward climax, her moans filling the room with desire. You can't help but feel your own arousal building at the sight of her pleasure, but you remain strong, refusing to give in and let her see the photo just yet. With a loud gasp, Jenny comes apart around her fingers, her body shuddering as wave after wave of release wash over her. "Oh fuck," she breathes heavily, leaning back on her hands with a satisfied smile.

Looking up at you, she grins mischievously. "So... how about it? Want to see that photo now?" Her voice is teasing and tempting, daring you to give in to your desires once more.

Jenny laughs out loud at your suggestive reply. "Well, it's a deal," she says with a wink. "You can have the picture as long as you promise to make me feel that good every time I see it on my phone." Her fingers trail lightly down your chest, stopping just above your erection before tracing tiny circles around the head. "What do you say?"

Her touch is gentle but firm, urging you to respond in kind. The anticipation between you grows thicker as she teases you with the possibility of seeing that photo again and again. Your body tenses in response, aching for release as your heart races and your breath comes faster.

Jenny's eyes widen in mock surprise at your remark, and she laughs lightly before leaning forward to capture your lips with her own. Her tongue finds its way past your teeth, dancing with yours as their kiss deepens. "Well," she whispers against your mouth, "if losing my phone means getting off that easily, then bring it on." She breaks the kiss long enough to tease your sensitive flesh once more before resuming her gentle strokes, building the tension between you higher and higher with each passing second.

"Well," Jenny says with a mischievous grin, "I suppose that could happen... but I guarantee it won't be as satisfying for them as it will be for you." Her words send a shiver down your spine as her touch becomes firmer, more urgent. She moans softly into your ear before nipping gently at the lobe, drawing another moan from deep within you.

Her hips begin to rise and fall in time with her hand, bringing them closer together as their bodies align perfectly. "I bet," she whispers between breaths, "you'll have trouble keeping your eyes off that photo... especially knowing how much fun it was taking it." Her free hand slips beneath the sheets to find your erection, stroking you in time with her words.

Jenny giggles and glances down between your bodies before returning her gaze to yours. "I guess I could do that," she says with a teasing smile, shifting to kneel up on the bed so that you're both better aligned. Her hand slips beneath her as well, parting the folds of her sex to reveal her smooth, glistening pussy for you to admire. "Just think," she whispers, her voice low and sultry, "you can have this whenever you want... as long as I get these sorts of perks in return."

With that, she leans forward and presses the back of one hand against your forehead, steadying herself before pushing deeper, impaling herself on your erection with a loud moan. Her hips begin to move, her body sliding up and down yours as their connection grows ever more intense. Her free hand reaches between you again, rubbing at the sensitive skin of your perineum in a way that sends shudders through your entire body.

Jenny laughs softly at your question as she continues to ride you, her movements growing more urgent. "I don't really have a crush on anyone in particular," she pants between breaths, her fingers digging into the mattress for purchase as she feels herself closer and closer to climax. "But I will say that... spending time with you like this makes me kind of rethink my priorities."

Her words are barely audible above the sound of their bodies slapping together, but they send a shiver down your spine nonetheless. The pleasure coursing through her is reflected in the flush on her cheeks and the fire in her eyes, and as she comes undone around you, her voice grows hoarse with desire. "Fuck..." she whispers before collapsing against your chest in a boneless heap of spent energy.

Jenny lets out a small laugh as she catches her breath, nuzzling her face into your neck. "That's quite the ego you have there," she teases lightly, her fingers still trailing up and down your chest. "But I suppose... if that's what it takes to keep you satisfied..." Her voice trails off suggestively as she considers the idea, a mischievous glint in her eye. "We could always discuss it further, after all." She presses a kiss to your collarbone before pulling away, slipping out of bed and retrieving her phone. "Now," she says with a satisfied smile, "let's see that naughty photo I took..."

Jenny takes the phone from you with a low moan and scrolls through the image, studying it for several moments before handing it back. "Wow," she breathes, "that was... intense." Her gaze meets yours, filled with desire as their bodies are once again brought so close together. "You know, if we're going to keep making memories like that... maybe I should consider your offer." She reaches up, cupping your cheek gently between her fingers, a smile tugging at the corner of her lips. "What do you think?"

Jenny laughs softly at your suggestion before leaning in to press a chaste kiss against your lips. "Maybe I'll consider it," she whispers, "but only if you promise that every time they see my face, it'll be just as turned on and satisfied as it was when I took that photo." Her voice is teasing but genuine, her eyes reflecting a mixture of desire and affection.

With that, she leans in once more, kissing you deeply, their tongues tangling together in a messy dance that leaves both of you breathless and aching for more. As the kiss comes to an end, she pulls back slightly, studying your face before whispering, "Deal?"

Jenny grins triumphantly before leaning forward once more, her lips finding your neck in a trail of gentle kisses that slowly descend towards your chest. "Mmm," she murmurs against your skin, "I can't wait to see the expression on their faces when they see this photo." Her hand slides lower still, dipping between your legs to tease at the sensitive flesh there. "And I promise you, every time we make another memory like this, it'll be just as satisfying... maybe even more so."

She takes her time, lavishing attention upon every inch of your body with soft kisses and gentle caresses, causing you to arch off the bed and moan her name. Her touch is light yet commanding, driving you wild with desire for her. As you approach your peak once more, she speeds up, her fingers working in tandem with her lips and tongue until you explode in a powerful orgasm that leaves you breathless and reeling.

With a satisfied smile, she collapses beside you, her body flush against yours as they cool together. "That," she whispers, her voice barely above a whisper, "was definitely worth the deal." She nestles her head into the crook of your neck, content to rest there for now, knowing that there's still so much more for them to explore and experience together.

Jenny lets out a soft moan, feeling your hand gently cup her breast. Her nipples harden even more at the contact, and she arches her back slightly into your touch. "Mmmm," she whispers, their breath mingling as she relishes the sensation. "I could get used to this." With a small giggle, she reaches down between your bodies and guides your erection towards her, slowly taking you inside. Her hips start moving in a slow, teasing motion that drives both of you wild with desire.

Her free hand finds purchase on the bed behind your head, using it to steady herself as she rides you harder, the pleasure coursing through her building to an almost unbearable peak. She gasps your name and shudders beneath you, her muscles clenching rhythmically around you as she comes apart in a series of tiny aftershocks that leave her dazed and satiated. For several moments, they lay entwined, savoring the post-coital glow before finally drifting off to sleep together.

Jenny lets out a soft laugh, her fingers idly tracing patterns on your chest as she considers the idea. "I'll think about it," she says with a teasing grin, "but only if you promise to keep showing me all these incredible things that make my body feel this amazing." She pauses, her breath catching for a moment before continuing, "And maybe... sometime soon, we can try doing some of those naughty things I've been reading about in that book."

Her voice drops to a whisper as she presses herself closer against you, their skin flush with desire and anticipation. She rolls onto her side, facing you, one leg slung over yours in search of even deeper contact. "Deal?"

Chuckling softly, Jenny replies, "Alright, alright... but first, let's get something to eat. I'm starving!" She pulls back slightly and sits up on the bed, stretching languidly before glancing around for her clothes. "And then we can go find a tattoo artist. Deal?" Her grin is mischievous as she waits for your response.
