Touching and rubbing wasn’t enough anymore.
I started pinching, licking, sucking… on various places I won’t specify.
I had read in erotic books that normal skin only tastes like sweat and salt… and yes, that was true, but… because it was my sister’s taste, it felt different somehow.
Her scent… not just sweat, but something fragrant and sharp that hit the back of my nose… yet it felt strangely pleasant, and I kept sniffing and inhaling it deeply.
The same book said that a woman’s scent smells good to men… I think this is what it meant.
I got bold and stripped her completely naked.
Her flawless white skin… seeing my sister’s nude body after so long made my cock painfully hard inside my pants.
Since touching her quite firmly didn’t wake her, I spread open her tightly closed slit and looked inside carefully… smelled it… and did the same to her back hole, observing it closely.
When I slid a finger inside her pussy, it squeezed tightly around me while the inner walls were soft, warm, and incredibly pleasurable… it felt like it was sucking my finger deeper.
If a finger felt this good, how amazing would it feel with my cock…?
I tried her back hole too.
The tightness was even stronger than the front… so strong it felt like it might bite it off… but inside it was also warm and soft.
When I moved my fingers around inside, she only let out a small “Nnh…” and twisted her body a little, but still showed no sign of waking.
Even with two fingers, then three, it was the same.
At this point, I was rolling downhill faster and faster with no brakes.
Of course I stripped her completely naked, and then I started changing her positions and poses however I wanted to make her easier to see and touch.
I took off my own pants too… and jerked off right there.
Naturally, with my sister’s naked body right in front of me, my cock was rock-hard, so I came after just a few strokes… but it wasn’t nearly enough.
Once, while straddling her sleeping body and jerking off, my aim slipped and I came directly on her instead of the tissue.
I panicked.
I quickly wiped it off and destroyed the evidence, but I wasn’t sure if I could completely hide the smell and feeling… that day I was scared out of my mind wondering what if she noticed.
But the next morning and the day after, there was no sign she had noticed at all.
After that, I got even bolder and lost all restraint.
Just watching and jerking wasn’t enough anymore… I started rubbing my cock against her naked skin, sliding it between various places.
Paizuri of course, thigh fucking, crotch rubbing, assjob, armpit job… I pressed it into her hand and made her grip it for a handjob, but since she didn’t move, I held her hand myself and stroked.
Because I was so hard, I kept exploding and spraying or smearing cum all over her, but as long as I cleaned up properly with wet wipes afterward, she never noticed.
It also helped that the sheets and duvet covers in her room were made of material that didn’t stain easily.
Even when some cum spilled onto the sheets, wiping it left no trace.
I later looked it up and learned it was special material.
While relieved, thinking that she probably bought these special sheets for sex with her boyfriend made jealous, lustful feelings surge up again that I couldn’t suppress.
Eventually, I started getting completely naked too, sliding my cock against her crotch and ass under the covers and cumming that way… …And today, I finally decided to cross the final line.
Today was a holiday, so during the day my sister had invited her boyfriend over for a home date.
I stayed in my room pretending to study while listening to music (actually nothing was playing).
As soon as they started, I went to peek.
Just like that other day, I watched his cock thrust deep into her pussy, pounding in and out… and finally saw him unload thick, white, sticky cum deep inside her without holding back.
Apparently my sister was on the pill for contraception.
I had overheard her telling her boyfriend the other day that they didn’t need condoms and he could cum inside her freely.
And just as she said, they were having raw, creampie sex.
I wanted to run to the toilet right away, but I held back.
Then night came.
After confirming my sister was sound asleep, I sneaked into her room.
Just like always, I stripped her naked and spread her legs.
Her tightly closed pussy was clearly visible.
I pressed the tip of my cock— which had been repeatedly getting hard and soft since daytime— rock-hard and throbbing, against her entrance.
I pushed firmly and forced it open.
The moment my tip entered, it was enveloped in a warm, soft, sucking sensation… I had done this much before— just the tip, then pulling out and cumming outside when I couldn’t hold back.
But today… I thrust my hips forward powerfully… plunging all the way inside her, to the deepest part in one go.
My thick virgin cock stretched her tight, velvety walls inch by inch, feeling every ridge and fold of her inner flesh gripping and rippling around my shaft as I sank deeper.
The overwhelming heat and wetness swallowed me completely, her pussy clenching rhythmically as if trying to pull me even further in.
“Nnh…!?” The strong stimulation of being pierced deep inside must have been intense; her body twitched hard.
Her breathing became slightly rougher, but she showed no sign of waking and continued her steady sleeping breaths.
