A Good Boy for Little Sis

I am Roger, most people call me Ram man, I am 21. I am 6 feet tall, I have dark hair and green eyes. I am slim, mostly hairless, with an uncut five and a half inch dick. I live alone in a small house.

Friday night, I am home alone, watching cam models, on Literotica. I have a bro sis role play ready in a second tab. I watch the cams, lightly teasing my dick to it's hardest state.

I lube up and switch tabs, stroking slowly as the scene starts.

A blonde girl convinces her big brother to stay home, by offering her body.

The model looks a lot like my younger sister Kate, a detail which definitely contributed to this being my favorite scene.

My mind drifts to the last time I saw my sis, two weeks prior, on her 20th Birthday.

Images of my sisters cleavage floating through my head.

I am stroking slowly when my phone dings, normally I would have ignored it, but when the girl you are stroking to calls you, well you answer.

"Hey big bro, are you busy?" Not too busy sis I think as I let go of my cock.

I reply "nah what's up?"

Kate asks if she can come over. I of course say yes and begin to clean up.

I close my laptop, stash my lube, and pull on some pajama pants. before heading downstairs to await my sister.

Kate arrives shortly thereafter.

I open the door, inviting her in, noticing she has a small bag.

Kate is wearing a baggy sweatshirt, and sweatpants.

I force my eyes off her bubble butt, as she drops the bag and turns to me. I see my sister's eyes are puffy, it is obvious she has been crying.

"Are you okay sis?" I inquire while opening my arms for a hug.

Kate nods as she falls into my arms resting her head on my chest. Kate is quiet for a moment as I gently rub her soft blonde hair.

"We broke up," She says as we disengage, I look over at the bag.

Kate nods, adding, "I could use a place to crash big bro."

"You are always welcome sis, stay as long as you want" I reply as she begins to smile.

Kate leans into me and kisses my cheek, "Thanks big bro, I knew I could count on you"

Kate manages a weak smile, as she moves to the futon.

I make hot chocolate, as Kate begins telling me what happened.

Explaining how her now, ex boyfriend, had been ignoring her a lot. Ignoring her advances in the bedroom and just not wanting to ever do anything with her.

"All he ever wants to do is play video games, and all I ever want to do is, tease and play with a hard cock"

Kate shakes her head in dismay as I stare open mouthed.

"Sorry bro but Your little sister loves teasing cock." Kate smiles naughtily and continues.

"So tonight was the final straw, I walked into the game room while he was playing his game. Kate takes a breath and continues, "I was wearing brand new lingerie, under my silk robe."

"Whoa sis," I say smiling in an effort to lighten her mood.

Kate smiles, and continues.

"So I walked in, I made sure he could see me, and opened the robe." Kate's eyes are down as she finishes.

"And?" I reply.

"Nothing" She says again shaking her head, "no reaction at all, except, hon I am having friends over."

"Wow" I say, a moment later, adding, "what kind of reaction were you looking for?"

My sis chuckles and replies, "well more of an erection than a reaction." Kate blushes slightly as we laugh.

"Aw poor sis" I say as I open my arms, she snuggles into me, her head on my shoulder, I toy with her hair as we watch TV.

"I would love that sis, if I came home to my girlfriend in lingerie, I have never had anyone do that for me."

I pause for a minute, and add, "Plus you love teasing cock, wow, your ex is an idiot."

I chuckle, shaking my head, adding "I mean most guys would be thrilled to have that happen, and he just ignores you?"

Kate nods, as I continue shaking my head.

"Wow, he really is an idiot" We both laugh as I finish, and I feel Kate relax a bit.

A short while later Kate goes upstairs to settle into my spare room, returning wearing lacy red thigh highs, and a white short silk robe.

I try not to stare as my sis walks back towards me, willing my cock to stop growing at the same time.

Kate notices my stare, she says softly, "I didn't really bring much."

Kate pauses for a sec and adds, "I was thinking, maybe, I could ask you something?"

"Sure hon what is it?" I reply.

"Well, I still have the new lingerie I bought on, and well, can I maybe show you?"

I am trying to figure out how not to sound too eager, when she continues.

"Just so, you know, I can see if maybe I am just ugly, or the lingerie is not sexy, or,"

I cut her off as she rambles.

"It's fine sis go ahead, oh and you are not ugly."

Kate smiles and has me sit facing her as she slowly opens her robe.

I feel my mouth fall open as I look at my gorgeous sister.

A lacy, slightly see through, black bra pushes her ripe young 34c boobs up and out.

I can just see the outline of her puffy areola, her torso is bare, her skin glows like silk.

A red frilly garter is around her waist and attached to her stockings. Her legs are long and supple.

Black lacy thong panties finish her ensemble.

"Wow sis" is all I can manage, as I stare at my sister's perfect boobs. I feel my cock grow to it's full five and a half inches instantly.

"You like?" Kate asks, smiling as I nod, my mouth still hanging open.

"Up here bro," Kate is giggling as she speaks.

I force my eyes away from her boobs and up to her face.

"He is an idiot sis" I repeat myself.

Kate, just laughs, and much to my dismay closes her robe.

Kate comes over to the futon, glancing down at my obvious tent as she sits.

"I see I got that erect, er I mean, reaction after all big bro."

Kate smiles at me cheekily, while I blush and stammer.

"Yeah, I um, Fuck sorry sis."

Kate just giggles and rubs my head softly, "It's okay big brother, my ego needed that."

Kate continues, smiling still, "So you approve of the lingerie obviously," Kate giggles as I nod.

"Can we find a movie or something?" Kate changes the subject.

I nod, relieved. Kate finds an old western flick, and we stretch out beside each other.

We cuddle quietly for a few minutes as I try silently and unsuccessfully to will my hardon away.

I am laying on my back, my head on a pillow.

Kate is beside me, curled into me, her head on my chest with her left hand draped across my belly. Her fingers are making soft little circles on my skin.

I am trying to focus on the movie, but having my gorgeous sister laying on me in lingerie is just a bit distracting.

I still have an obvious bulge, and every few minutes Kate's hand seems to be just a bit closer to it.

The feeling of the weight of her breasts, combined with the soft silk robe, is not helping at all. Her soft little hands, are just idly caressing me.

My hand is on her shoulder, toying with her soft hair.

"That feels nice big bro, I love when guys play with my hair, like that."

Kate lifts up and smiles at me for a moment.

When she turns, her hand is even closer to my bulge, now just above my belly button.

Her fingers again exploring, toying with the soft fine hair on my torso.

I feel a strong surge through my hard cock, and try to pay attention to the movie again.

Kate sits up a minute or two later, she is looking at my shirt, picking at something near my chest.

Kate explains, "there is something on your shirt, it keeps scratching my face, can you just take it off please?"

I sigh, sitting up as Kate smiles, I remove my shirt while she waits.

"Thank you big brother," Kate gives me a soft kiss on the cheek before we return to our positions.

Kate's hand feels good on my skin, her fingers making little circles on my tummy.

I resign myself to being hard for a while, chuckling inwardly as she idly plays with my belly button.

A few minutes later her hand is resting against the hem of my pajama pants, just above my obvious hardon.

I let out a little moan, causing Kate to turn her eyes towards me.

Kate smiles, "you're still hard big bro," her smile becomes even bigger before she adds, emphatically.

"For Your Sister." Kate giggles while I blush and stammer.

I collect myself a bit, looking down where her hand is.

I reply "Well fuck sis, I am only human."

Kate sits up as she replies.

"Sorry bro, I just can't help myself, once I know a guy is hard for me, I, just well."

Her words trail off as she sighs and again kisses my cheek.

"You do seem to like it," Kate says softly as she again settles into my chest, her hand now back around my belly button area.

I can't help but laugh a little, I sigh and rub her head softly, leaning closer I kiss her soft hair.

A few minutes later I am squirming again as Kate's little hand is on my thigh now.

I am having trouble stifling my moans."Kate, I," I begin but she cuts me off.

"Shh big brother, it's okay, just let me."

Kate says, as she turns to me, leaning in, she kisses my cheek softly.

Kate whispers in my ear, "just relax," before she snuggles back into my chest.

Kate is very good, my dick is soon leaking for her.

A visible wet spot just above my twitching cock head. I am squirming again as Kate giggles. Her fingers running up and down my thighs, across my belly, closer and closer to my throbbing dick.

Kate is leaning over me, her finger is tracing a path around my bulge, inches from my dancing cock.

I am squirming and moaning, mumbling softly.

As I mumble again Kate sits up. She turns to me smiling reassuringly, her little hand is resting beside my boner.

Kate's tone turns stern as she says, "Roger let your sister tease your cock, stop squirming, and just enjoy your teasing."

Kate looks at me sternly, her eyebrows raised, awaiting my agreement.

As I nod, Kate smiles and snuggles back in.

A minute later, Kate says, "I will only tease Roger, don't worry."

Kate turns her attention back to my dick, now combining soft kisses on my tummy, with her gentle caressing. Her eyes are glued to my throbbing cock and the ever increasing wet spot.

I moan steadily, my hands again in Kate's soft hair, as I live out my fantasies.

I am loving this attention, yet still somehow scared of it.

As the movie winds down Kate has one finger just barely inside my pj's, just under the hem.

Kate's finger is barely an inch above my cock head, as she runs it slowly left and right.

Kate's other hand runs up and my thigh.

My dick is visibly twitching, as Kate's fingers get closer and closer. Just when I am sure she is going to touch my aching cock, the movie ends.

Kate removes her finger, she lifts, my pj's slightly, she looks inside, as she whispers, "poor big bro, if only it was longer."

Kate adds, a second later, as she releases my pants, "all those old westerns are too short."

Kate giggles, while I blush.

Kate sits up, she kisses my cheek, before heading to the washroom.

I take advantage of the few minutes, trying to collect myself, and wrap my head around what just happened.

I would turn down sex with most women, right now, to go jerk off for my sister.

I pull my pj's forward for a second or two, now sitting.

"Wow," I mouth silently as I look at my aching cock.

A minute later she returns, Kate softly kisses my cheek. "I am going to bed big bro."

Kate pointedly moves her eyes to my bulge and then back to my face.

"Want another look at what you are about to jerk off to?" Kate says in a sultry voice.

I just blush and mumble with my eyes lowered, as Kate giggles.

Kate lifts my face to hers, and says, "It's okay to want to look at your sister. I just want you to say it."

I look up, saying, "I would love to see my little sister in her sexy lingerie." Kate smiles in approval

Kate stands and slowly opens her robe again, She lifts it and slowly spins, allowing me to see her gorgeous round ass in her thong.

I cannot stifle a soft moan as a wave of pleasure shoots through my aching cock.

Kate giggles as she turns, "You like your sisters ass bro?"

I nod again, unable to speak. Kate poses, facing me for a couple of minutes affording me a nice long look.

My eyes wander her perfect body, pausing every time I see her supple perky breasts.

"Wow sis you are gorgeous" I say in amazement.

Kate smiles and walks over to me, she moves her eyes to my tent.

"We have stuff I want to talk about big brother, but I need to sleep, and you need to jerk off, we will continue this though okay?"

"Yeah sis" I mumble as my mind whirls.

Kate again looks at my bulge, she smiles softly as she leans into me, "Don't be pulling it all night, er I mean an all-nighter," I blush brightly.

Kate giggles before kissing me softly.

She moves her mouth to my ear and whispers, "don't feel bad big brother, lots of boys get boners for their sisters."

Kate smiles brightly, as I sit paralyzed by confusion.

"Goodnight, thanks for the ego boost," Kate says.

She kisses my cheek softly, before heading up to bed.

I wait a few minutes and walk up the stairs, my small hard cock leading the way.

I crawl into bed after undressing and grabbing my lube.

I close my eyes, moaning softly, as my hand wraps around my pole.

The first orgasm comes way too quickly. I am so turned on though, I stay hard and manage a nice long slow stroke session.

Remembering how sexy my sis looked in her lingerie, I stroke nice and slow.

After my second orgasm I drift off to sleep.

The next evening, I arrive home from running some errands, as I walk into the living room, I hear "Surprise Big Brother."

My jaw hits the floor, as I see my sister standing in lingerie.

I feel my cock harden, as I take in the view.

Kate is again in her stockings, this time paired with a low cut, red satin teddy.

She twirls smiling, and raises the hem of her teddy so I can see her Ass again in a thong.

"Well you said no one had ever done this for you big bro, and well you have always been so sweet to me, do you like?" Kate asks.

Kate is smiling brightly as I reply, "Wow yeah sis fuck you look amazing."

I am frozen in a mix of fear and lust as my sis slowly walks toward me. Her pert boobs bounce as she moves, her cleavage is breathtaking.

Kate places her hand on my chest and looks down at my boner.

She purrs into my ear softly, "I think that's what they call an instant reaction."

She giggles softly as I blush, "you are a cock teasers dream big brother."

Kate runs her hand down my chest, over my belly, stopping when she reaches my belt.

"Um, are you kinda small?"

Her eyes are locked on my twitching little pole as she asks.

My eyes widen and I feel my cheeks redden.

Kate smiles softly, her hand gently caressing my chest. She again whispers, "it's okay if you are Roger, I love small cocked boys."

I just nod bashfully.

Kate kisses my cheek, she says softly "Go change into pajama pants, nothing else, and nothing under them."

"We can cuddle and talk. while I tease your little cock," Kate adds grinning.

I stand frozen in shock until she adds, "you want to be a good boy for me right big bro?"

I move to the stairs in a daze, my legs shaky. "Good boy" she says as I return in my tented pajama pants.

Kate has folded out my futon, and a ballgame is on tv the volume muted. "Lie down on your back," she says smiling.

"Okay" I reply as I lay down.

Kate smiles, she leans in and softly kisses my cheek, curling into me with her head on my chest.

"You are so compliant big bro, do you like being teased?" Kate asks in a soft sexy voice, her hand gently wandering my chest.

"Yeah I really do sis" I reply softly.

"Do you like when the girl takes control?" I just nod, my eyes down as I blush.

"Is the teasing even better cause I am your sister?" Kate turns to look at me as she asks.

"Um I err," I stammer, feeling myself reddening.

Kate giggles softly, adding "We can get back to that, I have other questions."

We lie quietly for a minute, Kate is running her index finger around my belly button as I moan softly.

She giggles in delight every time my cock twitches in my pants.

Kate turns to face me again, "Do you edge, when you jerk off?"

"Um yeah sis I do," I reply.

Kate grins, and says, "You jerk off a lot, don't you big brother?"

I just nod blushing again.

"There is nothing wrong with that" Kate says softly as she turns her attention back to my dancing dick.

For the next few minutes.Kate's hands feather my body, wandering up and down my thighs, around my belly button, closer and closer to my throbbing dick.

My soft moans and Kate's giggles the only sounds. Kate leans down and kisses my tummy softly before turning to me.

"I had an ex, last year, who was really into taboo stuff, he loved taboo porn and role playing."

Kate smiles as she continues, "I played his 19 year old, teasy little sister a lot, our fetishes worked well together."

Kate smiles at the obvious interest in my eyes.

"He kinda thought you might have a crush on me Roger, I mean at the time I dismissed it but now, I am not so sure."

Kate slides her finger under the hem of my pants as she finishes, eliciting a loud moan from me as she giggles.

"Was he right big brother?"

I blush again, not sure what to say, "We will get back to that" she says as she again lays on my chest.

A few minutes later, Kate reaches down to my drawstrings, loosening them, as she says softly "Here this will be better."

Kate slides her hand under my pj's resting it on my inner thigh, as she continues.

"I was thinking about this when I masturbated last night Roger."

I squirm at the thought, as Kate continues.

"I had a couple of friends in college, who loved being teased, and well I kinda had an arrangement with them , that you might like."

"Um okay," I reply, obviously intrigued.

Kate continues, "well I made them friends with partial benefits, or as I like to call them my snuggle buddies."

"Do you want to hear more?" Kate smiles as I nod eagerly.

"Well I would tease them, like I am teasing you, make out with them, wear lingerie, cuddle with them and role play."

My sis grins as she explains further.

"I would tease them gently about their little cocks. make them edge for me, and fill their spank banks."

Kate grins as she asks, "would you like to be my snuggle buddy big brother?"

"Wow fuck yes little sis" I reply, as she giggles, nodding.

"First rule I am a tease, the only one who will be stroking your little cock tonight is you, do you understand?"

"Um yeah sis I reply, nodding as I speak.

"Good boy" Kate says softly.

She lifts my pants up, loosening them even more, Kate slides her hand back under my pj's and onto my thigh, pausing as she reaches a pool of pre cum.

"I knew you would be oozing for me, have you ever tasted yourself?"

I shake my head as she scoops up a good amount on her fingers, "well you are about to."

Kate lifts her hand to me, offering me her pre cum soaked fingers.

"Taste how horny you are for your sister, good boy" she whispers softly as I obey.

"You might as well start getting used to the taste of cum," Kate giggles as my eyes widen.

Kate turns again laying on me as her hand slides back under my pj's.

Kate adjusts my pants, sliding just the back and sides of them down.

My twitchy little cock is barely contained, as my sister's fingers explore the uncovered areas.

"My two snuggle buddies were into taboo too," Kate continues softly, while her fingers drive me wild.

"That's how I know just what to say to drive a big brother crazy."

Kate beams before demonstrating.

"Did you ever think your little sister's hand would be so close to your little cock Roger?"

Kate has her hand resting beside my boner as she asks. I moan as she giggles softly.
