Haruna's entire body stiffened. A deep blush exploded across her face, turning her cheeks bright red. She could clearly feel the heat and hardness of my erection rubbing against her rear.
Because her mother and older sister were sitting right there, she didn't dare say anything. She simply bit her lower lip hard, trying to suppress any sound.
I wrapped my arms around her waist from behind, holding her securely. My hard cock twitched again, pressing even more firmly between her soft ass cheeks.
Haruna's breathing became shallow and quick. She squirmed subtly in my lap, which only caused my thick erection to slide slowly up and down between her ass. The thin fabric of her clothes did almost nothing to hide the sensation.
Kasumi, sitting to our left, noticed Haruna's flushed face. "Haruna? Are you okay, dear? You look really red…"
Haruna stammered, her voice slightly higher than usual. "I-I'm fine, Mom… It's just… a little warm in here…"
