Initially he was not going to be picked, but due to his reward from the system, her eyes gravitated towards him and he was picked as the sacrificial goat, so to speak.
Anyways, back to the present case.
Tristan was extremely uncomfortable and awkward. He sat as far away from the big sis as he possibly could, and tried to make the short period of silence less awkward.
"So… W-what's your name?" Tristan asked awkwardly, this was the best thing he could think of. Delaying the quest was not smart, but Tristan couldn't think logically right now. Wasn't it a bit hot in here? Is the AC turned off?
"Fufufu~ I love it when they ask such innocent questions, why are you sitting so far away? Big sis isn't going to gobble you up if you sit a little closer~ How about~~ In my lap?~" She slowly scooted towards Tristan, who was pushing against the door in sudden terror
She approached the terrified Tristan and slowly stroked his head. Ruffling his hair. She was marginally taller than Tristan, and she had mistaken him for an innocent child due to his height. The innocent part is correct, but he was actually 20.
She picked up the struggling Tristan with ease and set him in her lap. Tristan instantly stilled and his mind went blank.
'So soft!'
"Fufufu~ Not so scary, am I?" She seductively giggled.
"Now, then, you still want some candy, right? Do you want me to show you the 'tool' that you will use to extract this sweet candy?~"
Tristan wanted to shake his head so hard that his neck broke, but looking at the ever ticking timer, he could only nod reluctantly. He fully accepted that this situation was unsalvageable.
"Oh my~ So courageous! Very well~" Her nimble fingers zipped past his defences and traveled down his hairless stomach, before arriving at his zipper and unzipping it in one motion. Did she have 99 dex?! What is this skill!?!
Tristan tried to offer futile resistance instinctively, but against such determination and skill, what could he do? Absolutely nothing. That's what!
The unnamed big sis reached into his pants and grasped his slowly stiffening rising dragon! She was merciless!
"Fufu~ Do you know what this is called? It's called the penis! This is used to mine for some sweet juice called 'lube'. Would you like to know where you can find this sweet mineral? I happen to know of a local mine, very close by." She didn't give him a chance to answer, she was slowly stroking his length to full power, while her other hand caressed his chest through his thin shirt.
'W-woah! How is this thing so big? They're usually much smaller? Could he be naturally gifted? Or is this related to his ability?' She mumbled to herself, but then she just decided to take it for granted and let the lust cloud her mind again.
His dick was at full length finally, and she decided to educate this young soul on the matters of what happens between adults. He should be grateful, right? For the opportunity of learning such things from an attractive big sis, like herself.
She lifted him off her lap, and Tristan just remained silent. He had no idea what was going through her mind. Did she seriously think he was a little kid? He definitely looked old when he checked in the mirror in the morning, so wha-
The system.
His charm had originally been 8, which means he looked below average. However the system boosted his charm to 13. Which rejuvenated his skin, and with his short stature it also made him look more childlike. His aura of likeability also probably had something to do with the misconception.
Tristan decided to just shut up and let this pervert take out her urges on him. Better him, than an actual shota, right? His spirit of self sacrifice is truly powerful.
