For better appeal and previous part requests, I have added character names instead of second person. Now the story is for all incest lovers. Enjoy
Additionally, English is my second language so excuse my editing and punctuations a bit.
...
"Good morning, love. We should get up and clean this mess," I say, gently caressing Eva's face.
Eva takes a long stretch, and look at the wall clock. Its 9 am and only an hour before parents arrive. The quilt comes down her chest and because of it I am graced with a sight of her amazing breasts. Those brown nipples with hickeys on them--so delicious.
"Aye aye, sir," she says as she comes and deeply kiss me, her tongue swirling in my mouth dancing with my own tongue.
We both get up and shower together, teasing each other.
"I would have fucked her right here, but I am pretty sure her killed my cock last night," I whisper as I soap my baby sis' heaving breasts.
"Cock: death by fucking. Nice porno title idea," she giggles as we continue bathing.
Due to time constraints and the ticking clock, we decide not to go any further. We finish our bath and begin cleaning the bedroom and changing the bed sheets.
...
Eva comes down from her room in a yellow sundress with flowers on it. As I join her, I am graced with a smell of vanilla and lotion which she must have put to hide the smell of sex from herself.
"My sweet sister smells nice," I say, inhaling Eva's scent.
"You look nice," she teases back. "With that khaki shirt and your muscles bulging, it seems like the perfect way to make me... weak in the bones," she whispers.
I lightly punch her with a smirk as we see our parents enter.
"Hello, kids. How did you two hold up behind our backs?" Dad asks, laying down his luggage.
"Yeah, we managed all right," I respond, watching baby sis run to hug Mom.
We help them unpack and head to lunch, where I surprise everyone with a special dish of fish curry I prepared while Eva was bathing and our parents were still on their way.
"Oh, son, you shouldn't have."
I smile, brushing off the obligatory praises as we all start eating.
"So, what did you guys do there? Did you enjoy?" I ask them.
"Oh, son, thoroughly," Dad replies, glancing at Mom with a smirk.
Mom blushes and then asks us, "And what did you two do?"
"Oh, just the usual -- some hangouts, some parties, but mostly just enjoying each other's company," Eva responds as she sips her mango shake.
"Tell us about it."
"Will do soon," I say as we all finish eating lunch.
We steal glances and share naughty squeezes through the day but it's difficult to indulge in naughty sessions when parents are around.
...
All those naughty plays throughout the day worked up my baby sis, Eva, too much. At night I was sleeping soundly in my boxers in my room when she comes inside my room in just a pair of padded white bra and cute bowtie blue panties, her face flushed.
She climbs on my bed, slowly removing my quilt as she sees my decent muscles. She finds it difficult to control herself, all day of worked up tension seems too much as lewd thoughts take urgent space in her head, firing up sensations in all her lady bits; aching breasts, erect nipples, soaked pussy, and a charged and aroused clit.
She doesn't care about waking me up as she lowers my blue boxers to reveal my flaccid cock. As she unhooks her bra, she lets it fall down. The AC coolness blowing on her skin, makes her nipples even harder.
"Before checking for our pregnancy, I still want to do it once more, big bro just to be sure," she mumbles under her breath to herself as one of her hands urgently squeezes her right breast.
As she pinches her right nipple, her mouth goes on my flaccid cock and start sucking it. Instinctively, it starts getting hard as Eva works her hungry mouth, lathering it with her spit.
"Oh lord..." I mumble in my sleep as I start to wake up and I feel fuzzy as I see her in a haze, sucking on it.
My cock is now standing at full might, as she bites her lower lip, stand up on my bed, and yank her panties down to her ankles and come out of them. Her pussy juices connect her inner thighs with her panties.
"What?" I am about to say further,
But she cuts me off as she lowers her dripping cunt over my cock tip, before fully engulfing it inside herself.
"Ohh Yes! There," she purrs, and moans the same.
"Jesus... Sis!" I say, waking up as I start to register what's happening.
But she has already started grinding on me frantically as she starts riding me, pinching her own nipples.
"Oh lord, yes bro! Unghh... all this...oh...day staying a good girl...oh fuck!... has me worked up. Let me have you...oh...just a little bit...let me...yes!...fuck you for a bit."
She rides up and down on my cock as she tightens her pussy around my cock, pinching and squeezing her breasts and nipples, and frantically fingering her clit.
I feel used, but in a good way because what better way to be used and taken advantage of other than being a fucktoy for my sister for her to use me as she pleases. I find satisfaction in being her live dildo. I grab her waist as she slows down and look into my sleepy eyes.
"I am close baby, I am close, I am-"
Eva's moans are cut off as she cums on my cock, her warm pussy muscles snugly caressing and squeezing it thoroughly as her ample juices flow out of her pussy and drip down between us on my balls, and on the bed. Her arms grab the bed sheet below us, before she holds me tightly and ride her orgasm to the end.
Two or three strokes later, this does it for me as I erupt inside her, her eyes rolling back as I moan holding her down by the waist on my cock so I can thoroughly empty my balls in her.
"Ohhhh fuck, bro! Oh yes!... cum in me!...fuck!... bathe my insides in your cum...Ohhh Lord! Give me all of it...God!... Breed me...this...oh... pussy thoroughly," she moans as her eyes roll behind her head and she holds me in place by choking me lightly.
"Keep your voice down! Mom and Dad are just in the next room," I hiss, trying to quiet her as she finally relaxes.
