Hide! Quick!

Hearing sounds of someone approaching, Adrien simply does the first thing he could think of. Showing Marinette into his locker with him and closing the door behind them before she can protest.

The locker was dark and extremely cramped with the two people in there, he couldn't help but feel her body pressed against his. In fact, a very pressing concern was that Marinette's butt was very firmly pressed against his groin. If she hadn't noticed the bulge in his pants previously, it was obvious now. Both teenagers were holding their breath and trying to stay as quiet as possible, but Marinette couldn't help wiggle her bottom against Adrien's hardon slowly. 'Is this really for me?' she thought.

"Marinette, please..." Adrien whispers. Trying to make her understand that they need to be quiet. Unfortunately, she is so focused on his dick that she misunderstands this as a request for her to do more. With her face against the backwall of the locker and Adrien behind her, she can't see the horror on his face as she starts to slowly move her ass up and down against his groin. Neither can believe what is happening and both are blushing bright red, but Marinette still believes that this is what Adrien wanted her to do. That he is only hiding her in exchange for her pleasuring him and she can't take the risk of getting caught, so while listening to several guys in the room outside, Marinette and Adrien both try to stifle their moans as they slowly grind against each other.

There is so little room inside and Marinette wonders if she would be able to reach back and remove his pants...
