Option 5: Kokoro Ayase, 18 year old

With a twinkle in his eye, your grandfather introduced you to a group of five renowned JAV actresses, all of whom were under contract with your family's adult film studio.

They were as varied as they were vibrant: Hitomi Tanaka, a seasoned professional at 36 with her large, natural breasts and curvaceous figure; AIKA, a vivacious 32-year-old with a tanned body, green contact lenses, fake lashes, fake nails and dyed blonde hair; Ai Uehara, a playful 30-year-old with with her small stature, petite frame and expressive eyes; Eimi Fukada, a youthful 24-year-old with her idol like appearance; and Kokoro Ayase, a bright-eyed 18-year-old with an youthful face and curvaceous figure.

Upon entering, Hitomi Tanaka looked at your grandfather with an amused smirk, teasingly asking, "So, are we here for one of your infamous private parties, old man?" The room filled with giggles.

A crimson flush rose on your grandfather's cheeks as he sheepishly explained to you that these 'private parties' were, in fact, sex parties he hosted for himself and other powerful men. The actresses were paid generously to attend and have sex with your grandfather and his guests.

Your face turned into a grimace at the revelation, but AIKA was quick to reassure you, her voice soft yet confident. "Don't worry, kiddo. I actually enjoy these side gigs. The boss pays us quite handsomely, and the parties are always top-notch."

Just as you were about to respond, Ai Uehara chimed in, her voice teasing as she nudged your grandfather, "Hey, boss, who's the cute guy over there?"

With a proud smile, your grandfather patted your shoulder and declared, "Ladies, meet my grandson and the future torchbearer of our family legacy."

The room was immediately filled with a symphony of surprised gasps and a flurry of excited chattering.

Eimi Fukada, not to be outdone, coyly asked, "So, do you have a girlfriend, future millionaire?"

Your face burned as you shook your head, "No, not currently."

Your grandfather, seizing the moment, dropped another bombshell. He announced that he had assigned you the task of continuing the family lineage, promising a handsome reward to the lucky woman who would mother your heir.

The room once again exploded into a chorus of gasps and excited chatter, with each actress playfully arguing why they should be the chosen one.

Hitomi Tanaka, with a twinkle in her eye, takes the lead. "Well, I've got years of experience on my side," she declares, her hands on her hips, "and they say wisdom comes with age, right?" Her comment elicits a round of laughter from everyone in the room.

AIKA, next in line, steps forward, grinning widely. "True, Hitomi, age brings wisdom, but I bring the perfect balance of youth and experience. Plus, I'm a hit at parties," she adds, sending another wave of laughter through the room.

Ai Uehara, ever the radiant one, nudges AIKA aside playfully, batting her eyelashes at you. "Boys, they always like the youthful ones, don't they? Plus, I have been known to make people laugh. A sense of humor is crucial, wouldn't you agree?" She gives you a cheeky wink, causing you to blush.

Not to be outdone, Eimi Fukada, the youthful 24-year-old, steps forward with a confident stride. "Well, I may not be the oldest or the youngest here, but I'm at the perfect age to embrace both adventure and responsibility. Plus, I know a thing or two about keeping things exciting," she says, her eyes twinkling with mischief.

Finally, it's the turn of the youngest, Kokoro Ayase. She stands up, her cheeks a light shade of pink, and smiles shyly at you. "Well, I may not have as much experience as the others, but we're the same age. We could learn and grow together. Plus, who doesn't love a fresh start?" Her heartfelt words were met with warm applause and approving nods.

Amid the merriment and friendly competition, your eyes kept finding Kokoro Ayase, the actress who shared your age. There was a certain connection, a familiarity that felt comforting amidst the chaos. In the end, you chose her to be the mother of your child and future heir.
