Sex Education

'Carl is just a young boy, and an absolute virgin. He is completely clueless that he's fully erect right now. What a helpless kid.'

"Are you having a hard time controlling your puberty, Carl? I saw your thing last night, and it was just as erect as it is today," Lyra said softly as she walked closer. As his older sister, she felt it was her duty to show kindness and help her younger stepbrother.

"Stepsis..."

"What is it? You don't need to be shy around me. I know this stage of life is really tough for you," she reassured him, her soft fingers wrapping around his shaft and starting to stroke it before he even realized what was happening.

He had literally just woken up, and now Lyra was actively stroking his rock-hard dick!

'Jesus... ahh, what a wicked hand technique! Fuck this, this is a thousand times better than filming an adult movie!' Carl stood on his tiptoes as her palm worked its magic in a way he couldn't even put into words. If Clair's handjob last night was comparable to a top-tier adult film star, then Lyra's skill was on a whole different level entirely!

'Oh shit, I can't control my own dick!'

Stroke... stroke... stroke...

"Don't be shy, Carl. Morning wood is completely normal for a boy who's going through puberty," Lyra murmured, using her thumb to gently cap the sensitive tip of his dick while her hand continuously stroked up and down the shaft.

"Ahh... Stepsis..."

"Does this feel good for you right now, Carl?" Lyra asked softly. As the acting mother figure of the household, she convinced herself that this was entirely natural.

An older sister should always help her younger brother—there was no taboo in helping an inexperienced, virgin boy ease his tension.

"Y-Yes, Stepsis... ahh, it feels so good."

"Would you love it if I did this for you every single morning? I don't know what's been going on with you lately, but I can definitely help you relieve this stress." She gently cupped and massaged his testicles. Since they were hanging loose, her delicate touch felt like a burst of pure pleasure.

"YES, Stepsis... I desperately need your help...!"

"Haha, good boy. Then you can go ahead and cum for me." For the first time, Carl felt like his entire body was being completely squeezed dry.

Spurt! Spurt! Spurt!

"Oh my, look at that. This proves you're completely healthy. Look at how much morning cum you produced, Carl," Lyra noted, watching his heavy load spill over her palm and drip down onto the wooden floor after she capped the tip to catch the initial splash.

"Ahh... Stepsis..." Carl was utterly bewildered as to why she was handling him so assertively.

"You don't need to say another word. I'm going to take good care of you from now on, okay? Whenever you feel overwhelmed, just come tell me—I'll help you out."

"O-Okay..."

"Just promise me you won't do these kinds of things with anyone else, alright? I know what happened between you two last night, so don't do that again." She carefully wiped his dick clean with a hand towel before scrubbing the puddle of cum off the floorboards.

"What are you saying, Steps—"

"Shh, I heard the noise last night. It's difficult to manage your overflowing hormones when you're hitting puberty so hard. As the eldest sister in this house, I'll take full responsibility for handling it. Got it?" She offered a sweet, reassuring smile as she gathered the dirty bedsheets into her laundry basket.

"Hmn..." Carl nodded stupidly. Lyra literally knew everything that had transpired between him and Clair the previous night!

"Now go on downstairs—breakfast is already set on the dining table. Silvia mentioned that you need to stretch your body today, so she plans to take you outside with her for a light workout."

"Yes, Stepsis..." Carl nodded, feeling as though he were completely exposed and served up on a silver platter.

"I don't know what secrets you're hiding, Carl, but you can always rely on me." She smiled warmly, closing the bedroom door behind her as if nothing unusual had happened at all.

...

"What the actual fuck just happened...?" Carl stood frozen, his brain struggling to process the rapid turn of events. Lyra had made him explode in less than thirty seconds flat! And to top it off, she was completely aware of yesterday's incident, like it was no big deal.

"What the hell? Now this is definitely not something I expected to see." Carl was entirely speechless as he stared at the system text hovering directly in front of his face.

An actual Sex Education course!

"Does this mean I can't even make a single move on Clair or Silvia while we're inside the house?"

[ System Notification ]

Restriction: The host requires at least 75% progress in Lyra's Sex Education course before you can make any romantic or sexual moves on other family members inside the home.

"So the rule only applies inside the house. That means no sex under this roof until I level it up." He still couldn't wrap his head around how absurd the system rules were.

"But... honestly, it's not a bad deal at all. That touch, the precise way she used her fingers... without a doubt, that was the absolute best handjob I've ever experienced in my life, even back when I worked in adult entertainment." Carl couldn't disagree with the quality—her technique was genuinely on another level.

"Carl, what took you so long up there? Did Lyra do something to you?" Silvia called out the moment he walked down.
