Pleasurably for both. Although...

Jaune then plunged into her, bottoming out in one thrust. "Mmmm!" Emerald cried out through her gag. Jaune smirked and reached forward to grope both of her boobs as he began to pump in and out of her.

"You're really tight," he said. "Even after having a vibrator in your pussy for hours..."

"Nnnh," was all she could get out through the gag as she clenched her hands. He pussy clamped down as she focused on the sensations of being fucked.

"Speaking of your vibrator," he added, reaching over for it. She blinked from behind her blindfold, before her eyes visibly widened, due to Jaune beginning to press in into her ass.

"Mmmmmmph!" she cried out in a muffled manner.

"Mmmph indeed," Jaune quipped, leaving the vibrator in her ass as she strained against the ropes frantically, barely able to handle all the pleasure.

Jaune pounded into her, and resumed groping her pussy. Despite the gag, she was moaning out loudly, and writhing intensely. Jaune groaned and bottomed out a final time, before releasing his seed into her, eliciting a final muffled cry as she came, her body jerking while her back arched.

Jaune panted a moment, and removed her blindfold. She looked a bit loopy, but very contented. Then, they both froze as they heard Professor Oobleck from outside the classroom, "What the devil is that noise!?"

'Shit!' Jaune cursed as the handle turned, not noticing Emerald had quickly started concentrating.

The door flew open, and the Professor blinked behind his glasses, and scanned the room, completely overlooking the two in their compromising position. "That's funny... I could have sworn I heard something in here..." he muttered, before closing the door.

"...uh... What?" Jaune asked, confused as hell, before turning to see a slightly smug look in Emerald's eye.
