She stays standing

Hana fights the urge to move and stays standing as Yamamoto-sensei continues to run his tongue across her pussy and clit. She can feel the strength in her legs buckling as waves of pleasure take over, but she feels too greedy to stop even for a second.

He grips her hips tightly as he pushes his tongue inside her now. Hana gasps and gently grips the hair on the back of his head as he does, urging him to go deeper. He does. His hands slip under her swimsuit and grip her cheeks tightly, forcing her still as she wriggles and squirms at his touch.

“S-sensei~! Haa~!” Hana moans, her breathing speeds up rapidly and her legs are shaking more and more as each wave of pleasure crashed through her body. It takes all her strength and willpower not to collapse into him.

Her moans quickly become less shy now as she feels her body building up to a climax. She’s no longer thinking about whether anyone might hear them, and this only urges Yamamoto-sensei to dig deeper, to taste more of her.

“Aaahhh~~!!!” Suddenly she grips his hair with both hands and lets out a long cry of pleasure, as she cums. “S-stop” she gasps, and he pulls back as she collapses to her knees panting. She leans on him as she catches her breath, burying her face into his neck as he holds her.
