"Nng… do we really have to do this?"
"Of course! Skinship between siblings is important. Especially now that we're sisters, how better to bond than to wash each other's back?"
"No… uh… how is groping my breasts skinship?!"
Hatsumi has been unrelentingly pursuing my boobs ever since we got in here. Like a perverted old geezer, she's dead set on copping more than just a feel.
"S-stop, ahh!" I slap away hand after hand.
"I just don't understand why they're so large. Someone you like has been rubbing them, is that it?"
"Why— no! How did you even come to that conclu— uuuwwwah?!"
She rubs the underside of my breasts with soap and slips her fingers under my arms. This… this is not how skinship is supposed to work.
"Have you made a decision about what to do about school?" Hatsumi asks, her fingers slowly retracting from my chest.
I dread the inevitability of being found out. I know the longer I keep this a secret, the harder it'll be to reveal later. What's worse is the shuugaku ryokou. If I have to sleep with a bunch of guys in the same room during our school trip, there's no way that isn't turning into a gangbang.
The result would probably remain the same being in a room with a bunch of girls, too. Having Mio there makes that doubly worse.
"I talked to Kana about it. He's kind of against it. How do you think the school will react?"
Hatsumi works her fingers into my hair and scalp, turning my brain into mush. I never knew a head massage could be this incredible.
"They'll absolutely adore you, of course! Look how cuuuutteee you are!"
"When you put it that way, I'm less inclined to go through with it!"
Hatsumi, giddy as a child, climbs into bed after me. "Hehe! It's like grade school again. Except, you won't be wetting the bed this time, right?"
"Don't make me change my mind about sleeping together."
She grabs me and pulls me under her chin. "Ohh, I'm not letting my little Saeko go~"
Being wrapped in her arms in bed like this gives me a huge dose of nostalgia. All the times we slept together, stayed up together until we passed out, precious childhood memories of a worriless past.
Those times passed us by so quickly, and I'm the next to hit adulthood.
"I talked to Kana about college. He's going against his parents' wishes on Todai to go to Tsukiji instead. What do you think?"
"I think he's right to do what he wants. That should be the same for all of us." She purses her lips, likely recalling her past circumstances.
"What if what he wants to do is being externally affected, erm, by someone."
If I never turned into a succubus, Kana and I never would've had sex, and he wouldn't have confessed as a result of it.
"You're looking at this the wrong way," she says as a matter of factly. "People can't help being affected by one another. Sometimes, someone comes along and shows you a choice you didn't think of. Is it so bad? Haven't you met people who are like that for you?"
I think back to the unlikely company that I've met in the past week and say, "You have no idea."
"You can't know if Todai or Tsukiji is better for Kana. That's for him to decide. But I'm sure thanks to that someone, he's starting to think seriously about his future."
She's right, of course. Kana has been stuck on the path towards Todai for as far as I can remember. According to Hatsumi, I simply opened a new path for him.
That's good, right?
Am I the same way for Hatsumi? That can't be. Our parents paved the road for her, threatening to cut off her allowance and not provide any financial help to her unless she chose Tsukiji. All because they needed her to be my guardian in their absence. I was an impediment to her dreams.
How could you love me so much even when I was rejecting you?
As my nose begins to itch and eyes well with hot tears, it dawns on me how much she's sacrificed for my sake.
She took care of me nonetheless.
Hatsumi's a great cook, dependable, and hard working. The more I think about it, the more I see her as an ideal girlfriend. Heck, she's got the qualities for the perfect wife.
Growing up together, it was easy to see how she began to develop. The amount of times I'd seen her naked made it difficult to continue looking her in the eyes. The easily stimulated teen that I was— am, didn't leave much else to the imagination.
Thinking back… it seems like Hatsumi let me peek at her on purpose. I can't forget all those times she tried to invite me to bathe with her either. Tonight, too...
While we were bathing, I was never more glad to be a girl, without a dick to embarrass myself in front of Hatsumi with.
She's every definition of the word beautiful. Growing up, the boys around me always teased about introducing them to her. Of course, that made me jealous. Even though I tried to avoid Hatsumi's affection like the plague, deep inside I know I enjoyed being the only one to receive it.
I took for granted how lucky I was to have someone like Hatsumi.
Hatsumi puckers her lips. "How about a goodnight kiss like old times?"
"Awh, but families do this all the time. Just one quick peck!"
My mind is swirling, conflicted over her suggestion. All I can think of is how her breath smells like mint.
I never gave it much thought before, but Hatsumi has pretty pink lips.
"Fine, but you have to close your eyes."
Hatsumi screws her eyes close and leans closer. "Hehe! I love you~"
"I… I love you, too, sis." I close my eyes as well and crawl in to kiss her.
"Mmh, chu. Chu. Kiss— shllrrp, aahh… shhllurrrp… kiss!"
What begins as an innocent kiss is made passionate by Hatsumi's tongue slipping into my mouth. Her tongue and lips are so soft, it's like kissing a cloud or the surface of water.
"Wait… Hatsumi— chu! Mmmpph….nnnh— kiss! Haahh..."
She doesn't let up. She's got her lips fastened against mine. Her tongue takes the lead in my mouth, guiding it through a whirlpool of delight.
At this rate, I won't be able to control myself…
Hatsumi and I are going to end up— !
A hand slithers into my pants, it deftly parts my cunt and slides a finger into me. When I think that's the extent of her skill, a thumb brushes against my clit.
Why is she doing this? I never charmed her. Could it be my aura…?
Damn it. This is exactly what I didn't want, but it's… Hatsumi's so good at using her hand...
Her saliva is beginning to taste sweet, or maybe it's my own?
Not wanting to lose to my sister, I push back with my tongue. She's happy to receive it, opening her mouth wide to suck on my tongue.
Suddenly, she pulls away and giggles. "You used to stare at me so much, Saeko. Did you ever masturbate to the thought of your naked sister?"
"Hau—!" Another finger pushes into me. "Y-yes! I did… I used to… a lot…"
Hatsumi pulls out and licks the fingers dripping with my juices. Then she dangles them in front of my face, using my confession to take this further.
"A-aahh…haumff!" I clamp down on her slender fingers, savoring the taste of her saliva.
I catch a twinkle in her eyes before she drops down between my legs, pulling my pajama pants along the way. Her tongue caresses my already soaked thighs, and every warm breath teases my senses.
"Oh, it's quivering. Are you getting excited by your own sister?"
"Hatsumi, don't you think we're taking this too far? We're siblings— nngh?! Uunnaaahh!"
My mind flashes white as Hatsumi kisses my clit. Her tongue makes circles around it, and I'm losing my mind and reasoning to how good it feels.
Chu. Chu. Shllurrp. Lick!
"Haau… guh, Hatsumi— aaaahhh!"
"Saeko, you've been naughty playing by yourself." I look down to see Hatsumi licking a purple vibrator.
"W-where did you get that?"
I know I don't own sex toys... no. I do now. She must have found Hana's box—
She plunges it into me and grins with wicked intent.
"I'm not ready for this—"
"HHAAAUUuuuu— nngggaahh!!! Hatsumi, gah— aaaahhhh! Haaaahhh!"
I can't take it. I'm losing strength in my legs to the vibrator and Hatsumi's tongue-play. How is she this good? Has she had sex with other girls before?
My body tightens, I grab a fistful of her hair and push her head against my clit. Hatsumi continues to nurse on it even as an earthquake of an orgasm takes hold of me.
"I'm cumming, sis! Aahh— nnnhaaaahhhhhhhh!!!"
The vibrator slips out of my pussy. Hatsumi turns it off and shoves it down her throat, sucking every bit of my juices on its way out.
"Hehe, my adorable wittle sister is so delicious."
Hatsumi unbuttons her blouse and rips open my shirt. Without giving me a chance to catch my breath, she plants her lips down on mine. She wraps her arms around me and rolls me on top of her, then says, "Want to be a good girl and try eating out your big sister?"
With my mouth still dripping with her spit, I crawl down between Hatsumi's legs. She spreads them open to a pussy just as soaking wet as mine.
Above, Hatsumi looks at me with lust in her eyes, pinching her erect nipples. When I press my tongue against her clit like she did to me, a sharp yelp erupts from her.
"Ooh, Saeko… make me crazy with your tongue!"
I spread open her slit with my tongue and push into her pussy. The walls around it clamps down, quivering for more.
If Kotaro is being unfaithful, who cares? I just need to make her forget about him. Hatsumi belongs to me, and I belong to her. Family stick together, even if it's like this—
Mio said it's normal for succubi to have sex with their sisters, in that case…
"Nnh… mmmh! Your tongue is… aaaaahhh!"
Her legs squirm on either side of me, kicking the sheets off the bed in her writhing.
I never knew I could make Hatsumi feel this good. This could be considered a reward for her treating me so well.
"I'm cumming, Saeko— ooh… aaaaahhhaa, aaaaaaahhh!!"
I leap back onto her, shoving my tongue down her throat and rubbing my knee against her crotch. Her body continues to tremble from the aftershocks of her climax. I dry hump on top of her, rubbing our breasts and erect nipples against each other, gyrating my hips to knead our clits together. It's enough to kick us into another orgasm.
"Mmmmh! Mmmhmmppp, haaahhh!!"
Hatsumi moans into my mouth with the sweetest voice I've ever heard. Seeing this new side of my sister makes me want to do more…
"Hehe. It's your turn, Hatsumi."
I'm awakened to birds chirping outside my window.
It is twenty minutes to seven. Another peaceful school day Monday to look forward to.
I fucked my sister.
"Gusu… " I weep into my hands.
Just as I get up from the bed, the door swings open. I'm faced to face with Mio who has the biggest shit eating grin. I know what she's about to say, and I'm powerless to stop her.
"You fucked your sister!"
"ARGH. SHUT UP!"
