My Girlfriend's Mother is an AV Actress - Chapter 78

What’s Done is Done, Can’t Be Helped.

After school, we borrowed a room in Isogai-san's older sister's karaoke box and were preparing for the party. We spread light meals and snacks from the food menu across the table. Hitomi-chan and Isogai-san were already wearing see-through sexy underwear and erotic outfits, ready to be ravaged at any moment.

"Sorry I'm late... I got caught by the teacher."

"Oh, you're late. For now, strip off."

The last one to arrive was my younger sister, Erika. Ordering her to strip out of nowhere might sound crazy, but Erika obediently began to disrobe. Her slender rather than glamorous body was gradually exposed.

Forcibly stripping my sister butt-naked and thrusting my sex-education dick into her vagina—which had only experienced a strap-on before. Normally, this would be a mouth-watering situation, but for me, who has experienced an unbelievable amount of abnormal sex, it falls within the range of normal mode.

"Did you masturbate and get wet on the way here?"

"I pressed my pussy against the bicycle saddle and stimulated my clitoris while waiting at red lights. Just as sister-in-law instructed, I prepared it into a meat hole ready for immediate insertion."

Erika answered nonchalantly. Still keeping up that attitude even after coming here... hmm, as her big brother, I must discipline her. I also started stripping until I was butt-naked. Naturally, my dick was rock hard.

"Erika, sit there and spread your legs. Beg for my dick."

"...Ngh, yes. Please let your younger sister's pussy swallow Big Bro's male dick. I want you to give me immediate, raw creampie sex."

Gasping for a second, Erika obediently sat on the floor... and then spread her legs wide into an M-shape right in front of me to display her pussy. I reached my fingers out to the lewdly soaked slit and pulled it open wide.

"Ngh... Big Bro... ah..."

"Look how soaking wet you are already. A perverted sister who craves her brother's dick needs to be punished."

I signaled to Hitomi-chan with a glance. In moments like this, our eyes speak minds. Kneeling in front of my dick, Hitomi-chan gave me a blowjob to coat it with her saliva. In no time at all, it transformed into a slimy, obscene meat rod.

"Erika, speak up clearly about what you want and where you want it."

"In my pussy... I want... Big Bro's male dick. I want to commit incest... and become a sex-processing hole slave."

"Well said. Then here's your reward. I'm going to shove my raw dick into your super horny pussy. Where do you want me to ejaculate?"

"Of course, creampie, please. But if you want to cover me, feel free to dirty my face or hair, anywhere you like."

"Good for you, Erika-chan. Even as siblings, you get to have Shota-kun's dick. Let's get along as dick-sisters from now on♪"

"Yes, sister-in-law❤️...What are you doing, Big Bro? Hurry up and shove it in to make me lose my dick virginity."

You... this girl is pretty bold too. Can't be helped; as her brother, I must discipline her with this extra-thick rod... I applied the glans to her vaginal opening and shoved it in without holding back. Since she had already lost her virginity to a strap-on, there was naturally no hymen resistance. Smoothly, welcomed by the vaginal walls, the shaft invaded my sister's pussy.

"Whoa, they're really doing incest..."

Isogai-san raised her voice in complete disbelief. Well, normally that would be the reaction, but since Erika has lesbian tendencies and has no intention of getting a boyfriend anyway, it should be safe. I smoothly pulled the shaft out and showed it to Erika.

"This is proof that I shoved it into your pussy. Lick it clean once."

"Yes... Please let me lick and clean my own pussy juices."

An surprisingly obedient response. Given that Hitomi-chan's pussy juice is the ultimate nectar, she doesn't seem to mind love juices much. Opening her mouth submissively, she began licking my shaft.

"You've been made into a woman by Big Bro's dick."

"That's right. I'll make sure she learns the taste of semen, too."

Forbidden incest... yet in this sex party, it's merely an appetizer. In fact, Hitomi-chan, having finished setting out drinks and food on the table, was pressing her breasts against my back while nibbling my earlobe and playing with my nipples. Isogai-san had also started a lesbian kiss with Erika.

"Ngh... ah, if I'm kissing, I'd rather do it with sister-in-law... ngh, ahhn❤️"

"Heh, if you want Hitomi-chan, you'll have to get through me first..."

It seems Isogai-san has the upper hand between the two. As expected of someone called the school prince, her way of doting on girls is cool. As their tongues intertwined, Erika's expression melted. Seeing Isogai-san's serious face up close, she really looks quite handsome. That slightly stubborn look is great, too. Violating a helpless Isogai-san while she glares at me is truly a pleasure.

"Haa... ah, ngh, ah...❤️Big Bro. Inside me... ejaculate raw. I want to be just like sister-in-law..."

Erika must have gotten horny too, as her begging grew intense. Shoving my dick deep into her vagina, I gouged out her vaginal walls without mercy. With impressive sensitivity, her sweet gasps while swaying her side ponytail heightened my arousal. After all, violating one's own sister has incredible ethical destructive power... a failing grade for life is guaranteed.

"Aah, ah, aah❤️... Oh no, Big Bro... wait, I'm coming... ah❤️"

"Don't hold back. Try saying 'My relative's dick is the best, raw creampie incest sex is the best' while you cum."

"How could I say... ah, aahn❤️Big Bro's raw dick is the best. Even though it's wrong, being watched like this... incest feels so good!"

"Well said. Here's your reward then: I'm going to turn your pussy into my semen toilet, so take it all in."

Grabbing Erika's hips firmly, I went into the final sprint. The clapping sound of obscene flesh hitting flesh echoed throughout the room, and she began groaning in a melted female voice unthinkable for siblings. She's actually pretty cute... I made eye contact with Isogai-san, leaned over Erika, and kissed her.

"Ngh❤️... chu, mmm... nnn❤️"

"Erika-chan, you're cute. Big Bro's raw dick feels good, right?"

"Yes... sister-in-law❤️ Ah, aah, I'm coming, I'm coming...❤️"

"I'm at my limit too. Cum from internal ejaculation and declare yourself my female slave while Hitomi-chan watches."

"Yes❤️I, Erika Kagawa... will become Big Bro's exclusive meat toilet slave❤️ Big Bro... aah, I'm cummmming❤️❤️"

The moment she hit climax, Erika wrapped her legs around my waist. Squeezing her vagina tight... the instant her vaginal walls sucked onto my glans, I blasted my semen with all my might.

Squirt, gush, splat❤️

Throb, pour, gush... squirt, spurt, gushhh❤️❤️

"Ah, aah... hot❤️Inside my pussy... so much is being ejaculated from Big Bro's raw dick...❤️"

Erika had an ecstatic look, intoxicated by the internal ejaculation. She fell quite easily... but I was continuously excited too. My heart was pounding. It didn't feel like much while violating her, but once ejaculation was finished, the reality hit me that I had cum inside my sister. If my parents find out, I'm dead in every sense... I mean, even if Hitomi-chan is a green light, being seen by Isogai-san is already dangerous...

"Don't worry, I won't betray you like that."

Hmm? Who was it that sent the video of me having affair sex with Honami-san to Hitomi-chan's phone again? Oh well, if she says so herself. Pulling my dick out, I brought it to Erika's mouth to let her give me a cleaning blowjob.

"Here, it's your memorable first creampie dick. Be grateful and suck it. Hitomi-chan, as a reward, give Erika a cleaning cunnilingus."

"Okay, then Erika-chan, spread your legs a bit more... yeah, thanks. That's so naughty, ngh. Chu, mm, lick, slurpp..."

"Aah, ah, if sister-in-law licks me there... no, I'm sorry... iiiih❤️❤️"

Ah, she squirted. Hitomi-chan's face must be soaked with love juice mixed with semen... As punishment, I shoved it into Erika's mouth, switching to a cleaning irrumatio.

Terrifyingly enough, this was merely the appetizer of this sex party.

To repeat, it was merely an appetizer.
