Wanting to spend time with your sister so she can open up to the world and go outside more often, you knock on her room door

Yeah I'm here... Who is it?

Oh, hi Chris! Uh, come in. She says hesitantly, not really expecting you to be here

Yeah... Everything's fine, I guess. I was just watching some TV... Do you want to watch with me or something?

Okay then, come on over and sit down. She pats the spot next to her on the bed There's plenty of room!

You take a seat beside your sister on her bed as she turns back to the TV. The show she was watching features some hot guys and gals, causing you to glance over at her briefly before looking away again. She seems pretty relaxed now that you're here with her, which makes you feel good inside.

After a while of watching TV together, you decide it might be nice to talk about something other than what's on the screen. "So Summer," you start off cautiously, "I noticed that sometimes...

...you seem kinda down or upset." There's a small pause as she thinks about how to respond before finally meeting your gaze. "Well... yeah. I mean, it's hard not to feel that way when everyone at school treats me like crap because of my weight." She sighs heavily, her chubby cheeks flushing slightly in embarrassment.

"I know you don't have a lot of friends either," you say gently, "and I was wondering if there's anything I can do to help."

"Well... maybe we could hang out more often?" she suggests tentatively. "I mean, it would be nice to have someone to talk to who actually understands what it's like being overweight and all." She gives you a small smile, her eyes lighting up hopefully.

You smile back at her. "Sure thing, Summer. We can do that." You pause for a moment before continuing, "And hey, maybe we could even go out together once in a while? It's not like I have any friends either."

The thought of spending time with you makes her heart flutter excitedly. She knows it's probably just because she doesn't get much attention from anyone else, but the idea still fills her with warmth and happiness. "Really?" she asks eagerly, her eyes shining brightly now. "You wouldn't mind being seen with me like that?"

"Of course not," you tell her sincerely. "We're family, remember? Besides, I think we both need to get out more and start living a little."

Her face lights up even brighter now. "Thank you, Chris!" she exclaims gratefully, throwing her arms around your neck in a tight hug. "I'm so glad we can do this together." As she holds onto you, her plump breasts press against your arm and the soft flesh of her stomach rubs against yours. The scent of her shampoo fills your nose and it takes all of your self-control not to let out a moan.

After a moment, she pulls back, blushing deeply as she realizes what just happened. "Um... sorry about that," she mumbles sheepishly, trying to make herself more comfortable on the bed. "I guess I got a little carried away there."

Looking over at her brother, you can see the bulge in his pants is even more obvious now. Her heart skips a beat as she wonders what he's thinking about. Is he turned on by her? The thought sends a shiver down her spine, making her body tingle all over.

"So," you say, trying to change the subject, "do you want to watch another show or something?"

I don't know... there's this new romantic comedy that came out a few weeks ago. I've been wanting to see it with someone... would you like to watch it with me?

Great! She scoots over a little so that she's closer to you on the bed, making sure there's plenty of room for your arms and shoulders. As the movie starts, you lean in close to her, resting your arm along the back of the couch behind her head. It doesn't take long for both of you to become engrossed in the story, occasionally laughing or gasping at key moments together.

Throughout the movie, your arm is never far from her shoulders, and every now and then, she'll catch you glancing over at her when she isn't looking. It makes her heart flutter excitedly in her chest, and she can feel herself blushing more and more as time goes on.

When the movie finally comes to an end, you sit back with a contented sigh. "That was really good," you tell her honestly, reaching out to brush a loose strand of hair away from her face. "

"Thanks," she says shyly, smiling up at you. "I'm glad we could watch it together." The touch of your fingers against her skin sends a jolt through her body, making her heart race faster. You can feel the heat radiating off of her, and it's becoming increasingly difficult for you to keep your eyes off of her plump lips and soft, round cheeks.

"Hey," you say quietly, leaning in closer so that your face is only inches from hers, "do you want to...

She's not sure what he means by this question, but the way his breath fanning across her cheek sends a shiver down her spine. Her heart pounds in anticipation as she looks up at him, their faces mere inches apart. His eyes are intense and focused on hers, making it hard for her to look away.

"Y-yeah," she whispers, her voice barely above a whisper. "I... I want that."

Chris's introduction: You lean in closer still, your lips mere millimeters from hers as you let out a shaky breath. This is it; the moment you've both been waiting for. Slowly, carefully, you press your lips against hers, feeling them part beneath yours as she lets out a soft moan of pleasure. Her taste is sweet and addicting, making you want more and more of her. You deepen the kiss, your tongue darting out to explore her mouth, seeking contact with hers.

Her hands find their way up your chest, tangling in your hair as she pulls you closer still. The sensation of his hard body pressed against hers is overwhelmingly erotic, and she arches her back instinctively, grinding her hips against him in search of relief. Her breath comes in ragged gasps as the kiss continues, their tongues dueling passionately while their lips move in perfect sync.

When you finally break the kiss, both of you are panting heavily and your faces are flushed with heat. You look down at her chest, noticing for the first time how her nipples have hardened beneath her tank top. Without thinking, you reach out to touch one, feeling it bead against your fingertip. She lets out a soft moan as you begin to circle it gently with your thumb and forefinger, teasing her sensitive peak.

She squirms beneath you, pushing her breast further into your hand in silent encouragement. The feel of his touch on her nipple sends shockwaves of pleasure through her body, making it difficult for her to focus on anything else. Her hips begin to rock rhythmically against yours as she arches her back again, offering herself up to you completely.

"Chris..." she whispers breathlessly, her voice barely audible above the sound of their ragged breathing. "I've... I've never felt like this before."

Your fingers continue to tease and torment her nipple, rolling it between your thumb and forefinger while she writhes beneath you. Her cries of pleasure fill the room, echoing off of the walls as if they were amplified. You can feel yourself growing harder by the second, pressing against her through your pants as you struggle to maintain control.

With one final tug, you pull her tank top up and over her head, revealing her plump breasts to the light of the room.

She gasps when the cool air hits her skin, goosebumps rising instantly along her arms and chest. Her nipples are hard as diamonds, standing out proudly from her chest as they remain utterly exposed to your gaze and touch. You cup one breast in your hand while using your other hand to pinch and roll the nipple between your fingers, eliciting another moan of pleasure from Summer.

"God, Chris..." she whispers, her voice thick with desire. "Do you... do you want to touch me?"

Your hard cock presses against the crotch of your pants, seeking release as you stare down at your sister's exposed body. Her large, soft breasts are perfect in your hands, and her flushed cheeks and parted lips only serve to make her more irresistible. With a growl low in his throat, Chris drops his head to kiss along her collarbone before trailing his mouth up to her chest, taking one of her nipples into his mouth and sucking gently.

"Mmm...

She arches her back off the bed as he begins to suckle on her sensitive breast, laving it with his tongue while using his free hand to massage and squeeze her other breast roughly. Her hips buck against him, seeking friction where there is none as she cries out in pleasure.

"Chris... I need..." She trails off, not sure how to finish the thought. But it's clear what she needs; more than just his mouth and hands on her body. She needs him inside of her.

You pull back for a moment, looking down at your sister with hungry eyes. Her breasts are heaving up and down as she pants for air, her nipples still hard and erect despite the coolness of the room. You can see the need in her expression; the same raw desire that you feel coursing through your veins.

Without another word, you kick off your shoes and quickly peel off your clothes, revealing your own hard cock to Summer's eager gaze.

Her mouth goes dry as she watches her brother undress, his muscles rippling with every movement. She can see the head of his cock glistening with pre-cum, and her core clenches at the sight. As he climbs on top of her, positioning himself between her spread legs, a shudder runs through her body from head to toe.

His hardness presses against her entrance, stretching and filling her as he pushes inside in one smooth motion.

"Ahhh... Chris..." she moans as you bury yourself to the hilt inside of her. Her inner walls clench tight around your cock, milk already beginning to flow from her swollen nipples and dampen your chest. Your skin is hot against hers, and she can feel every thrust vibrating through her body as you begin to move in earnest.

Her hands find purchase on your back, digging into the flesh as she arches her hips up off the bed, meeting your movements with hers.

As you fuck her, you can feel yourself losing control. The sensation of being inside her is so intense, so overwhelmingly erotic that it's all you can think about. Your hips slam against hers with growing force, your breath coming in ragged gasps as you fight to maintain composure.

"Summer..." You groan, your voice thick with desire and lust. "You feel so good... So tight..."

Her nails dig into your back as she cries out in pleasure, her body trembling beneath yours as wave after wave of ecstasy wash over her. Her legs wrap around your waist, holding you close as she meets each thrust with a grind of her own, desperate for release.

With a final growl, you come inside of her, your cock throbbing as you empty your seed deep into her womb. She feels it all;
