At home
Leon opened the door and stepped inside. He saw his youngest sister Lily in shorts, happily eating bread at the table. He walked up behind her, wrapped his arms around her waist, and asked softly, "Lily, where is everyone?"
Lily looked surprised, her cheeks turning pink. "Big brother… everyone is out at work. I was bored at home alone."
Leon's hands stayed on her slim waist. "Well, let's play. Come to my room."
He took her hand and led her to his bedroom, closing the door behind them.
Then after two games"
Leon sat on the edge of the bed and pulled Lily close. "Baby, your big brother is having a hard time holding back. Help your brother out, okay?"
Lily lowered her head, flustered and shy, her voice soft. "Brother… I don't know how to lick. I've seen it before, but I don't know how to do it properly."
Leon's heart raced at her innocent words. He gently took her small hand and pressed it against the growing bulge in his pants. "If you don't like it, brother won't force you. Just use your hand for now, okay?"
Lily nodded slightly, relieved yet curious, her innocent face flushed.
Leon licked her small ear and whispered, "Baby, help your brother take off his pants. They're too tight."
"You… take them off yourself," Lily moaned softly, embarrassed.
"If you don't, brother might take yours off instead…" Leon teased, his hands sliding down her fair legs.
Lily took a deep breath, her face red. She reached out with trembling fingers and pulled down his pants and underwear together.
Leon's thick, rigid cock sprang free, throbbing hard, radiating strong masculine scent.
Lily stared at it with wide, curious eyes, her breath brushing against the tip. "Brother… it's so big…"
"It likes you so much," Leon panted. He took her soft hand and wrapped it around his shaft. "Hold it properly, Lily."
Lily's delicate fingers circled him. She stroked shyly at first, then more steadily, her innocent eyes looking up at him. "Does it feel good, brother?"
"So good, baby," Leon groaned, thrusting lightly into her palm. "Use your other hand on my balls."
"Perverted brother…" Lily whispered, but she obeyed, gently cupping and caressing his balls while stroking his cock.
Her small hands felt incredibly soft and warm. Leon watched his 20-year-old innocent sister kneeling between his legs, pleasuring him with pure curiosity and shy obedience.
"Lily, come closer," he said huskily.
She leaned in, her face inches from his throbbing cock. Leon guided her gently. "Lick it, baby. Just like you've seen."
Lily hesitated for a second, then stuck out her little pink tongue and gave the head a tentative lick. The taste made her blink, but she licked again, running her tongue along the underside.
Leon moaned deeply. "That's it… good girl. Lick all over."
Encouraged by his praise, Lily licked more eagerly—long, wet strokes from base to tip, circling the head, tasting every inch of her big brother's cock. Her innocent face looked so pure even as her tongue worked on him.
Leon's hand rested lightly on her head. "Suck the tip now, Lily."
She opened her small mouth and took the head inside, sucking gently while her tongue swirled. Her cheeks hollowed slightly as she tried her best, looking up at him with shy, watery eyes.
Leon groaned louder, hips moving slowly. "Fuck… your mouth feels so good, little sister."
Lily kept licking and sucking, her saliva coating his cock, making it glisten. She licked his balls too, taking one gently into her mouth before returning to the shaft.
Leon felt his climax building fast from her innocent efforts. He pulled back slightly, stroking himself while she licked the tip.
"Open your mouth, baby… brother's going to cum."
Lily obeyed, tongue out, innocent eyes locked on his. With a deep groan, Leon erupted, thick ropes of cum landing on her pretty face and tongue.
Lily blinked in surprise but stayed still, letting him finish. Some cum dripped from her chin as she looked up at him shyly.
Leon breathed heavily, stroking her hair. "Good girl, Lily."
