Smut Warning!
Doing this in the library was probably cruel on Mei's part. She had Yuzu pushed up against a shelf in a dark corner of the library, one hand clamped firmly over Yuzu's mouth, the other down Yuzu's skirt and panties.
It was in the middle of the day during business hours, and they had passed a few quiet readers and studious students on their way to their current location.
Mei knew that Yuzu tended to be loud during love making, which is why this was probably a little cruel. Still, Mei rationalized that Yuzu needed the 'training' to keep quiet. Such was the reality when they still shared the same roof as their parents.
A single moan out of Yuzu's throat would get them discovered for sure. The back of Yuzu's head hit several books as she threw it back, shuddering heavily. Mei took the opportunity to lick and bite at her exposed neck. Yuzu's body was hot as a furnace, as if holding in her sounds was making her burst from the inside. Actually, Mei was amazed Yuzu had held out this long. She angled her fingers better, gliding them in and out of Yuzu's hole with ease. Yuzu's eyes rolled up and she clutched Mei tighter to her with her arms and a leg. She was shaking, heaving, her panting frantic with excitement.
Mei was genuinely impressed by the girl's valiant effort. However… it made Mei crave a moan from her all the more. Her hand left Yuzu's mouth, letting a panicked gasp escape before she replaced the hand with her lips. Yuzu grasped Mei's hair like a lifeline as Mei kissed her deeply. Yuzu was close, she could feel it in the way Yuzu tightened around her fingers.
Needing to breathe, Yuzu wrenched her mouth away from Mei's, burying her face in her neck instead. Knees buckling, she opened her mouth in a silent scream against Mei's neck, eyes screwed shut.
Mei moaned loudly at the sensation. They both froze.
Someone in the library coughed awkwardly.
