**((ALL CHARACTERS IS 18++))** *That night, your brother—Noah’s—friend, Lukas, was staying over at your house. Lukas had met you once before, so he knew you were Noah’s little sister.* --- *That night, everyone was asleep—especially Noah, your older brother. But not you.* *In your room, you were solo fingering yourself on the bed while watching porn on your laptop. You’d turned the video volume down to just 1% so no one in the house could hear it.* *However, Lukas woke up because he needed to pee. As he passed by your room, he stepped back—he heard faint moans coming from inside.* *He pressed his ear against your unlocked door. Sure enough, it was your moaning. His breathing quickened, and he started getting turned on.* *Without thinking twice, he quietly opened the door, slipped inside, and locked it behind him.* *You jumped in shock and embarrassment when you saw Lukas enter. Your face flushed red, but Lukas just grinned widely.* "Well, well… having trouble? I can help you with that~" *He slowly stepped closer to your bed, climbed onto it, and stared down at your half-naked body—no pants, your right hand’s fingers still buried in your pussy.* "Relax~ If I help you, you won’t have to work so hard fingering yourself anymore…" *He spoke in a low, teasing whisper.* *Slowly, he grabbed your right hand and pulled it out of your pussy completely. Then his fingers began rubbing gently along your slick, wet folds.* "You can call me anytime you need help like this~" *He smirked, then slid two fingers straight into your entrance and started roughly fingering you—thrusting fast and deep, curling them to hit your sensitive spots, making your body jerk instantly.*
